J'ai donc décidé de modifier mon FT817ND pour qu'il charge la batterie dès que je le connecte à une source d'alimentation externe, notamment via un système de panneau solaire quand je suis en portable.<br />
Il est donc en charge constante à 250mA, sans timer. Il faudra alors surveiller soi-même la durée de charge.<br />

La modification est très simple: si suffit de shunter le transistor de commande de charge. En mettant l'émetteur du transistor à la masse, on valide la charge. La commande du timer est alors inutile.<br />

Il faut se concentrer sur le circuit Main Unit, la partie bottom. Il faudra démonter la carte Main Unit complètement, car la zone n'est pas accessible. Attention les nappes sont très fragiles.<br />

Je pense que je suis arrivé à la version la plus simple qu'on puisse faire.<br />

Pour cela il faut imprimer les pièces, les fichiers sont disponibles ici:<br />

Nous avons imaginé et élaboré un jeu qui consiste à manipuler correctement les lettres à la pioche.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://2.bp.blogspot.com/-sFGuSgVypeE/WZiT9XZjLWI/AAAAAAAA65M/hwgqeHrgo0EBecNajQWX6aprBD0bKnIdQCLcBGAs/s1600/morse3.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="669" data-original-width="1268" height="168" src="https://2.bp.blogspot.com/-sFGuSgVypeE/WZiT9XZjLWI/AAAAAAAA65M/hwgqeHrgo0EBecNajQWX6aprBD0bKnIdQCLcBGAs/s320/morse3.jpg" width="320" /></a></div>
<br />
Alain F5RUJ a fait le plus gros du travail dans la programmation de l'arduino.<br />
Le principe est simple: on manipule une pioche et les lettres s'affichent sur une matrice à led.<br />
<br />
Un article est disponible dans l'un des numéro de La PIOCHE de l'UFT en 2017<br />
<br />
Comme je vais utiliser cet équipement à l'extérieur, pour des raisons de visibilité, j'ai préféré faire l'affichage sur un écran LCD Alphanumérique. La tonalité sort du haut-parleur.<br />
<br />

Le circuit s'alimente avec une pile 9V, via un régulateur 7805. C'est un arduino mini-Pro que j'utilise et des écrans LCD de récupérations. L'audio sort par un GPIO de l'arduino, un signal carré à 700Hz. Une résistance série avec le GPIO, et potentiomètre de 10kOhm logarithmique atténue ce signal carré. C'est un module audio à base de LM386 CMS qu'on trouve sur EBAY qui fait un amplificateur pour le HP de sortie de récupération.<br />
Au fur et à mesure de la manipulation, les caractères ALPHA NUMERIQUES s'affiche sur un écran LCD 2x16 caractères.<br />
Pour optimiser l'affichage, il n'y a pas d'espaces entre les mots. <br />

<br />
<br />
C'est un prototype qui a des bugs:<br />
- Quand le contact de la pioche est trop longue, le logiciel plante. Il faut attendre un peu, sans manipuler. ça se remet tout seul.<br />
<br />
-
La fermeture du boitier n'est pas vraiment optimisée, j'ai fini par
coller le couvercle pour m'éviter des vis qui dépasses. Mais c'est pas pratique en cas de mise à jour<br />
<br />
Sauf si je trouve à l'utilisation que ces bugs sont très gênant, je ne compte pas les corriger.<br />
<br />
En tout cas, ça fait un bel atelier de démonstration et de jeu pour les plus jeunes.<br />
<br />
Je vais utiliser ces appareils dans des ateliers Radioscoutisme.<br />
Ces ateliers seront agrémenté d'un support disponible ici:<br />

<br />
A base de "Transmitter Module 433MHZ TX5" acheté sur ebay.<br />
Il s'agit d'un TX 433 MHz, à base d'un quartz 13,560MHz et d'un SYN115 (PLL*32).<br />
<br />

Ce TX 433MHz fait de l'ASK, et pour mes applications le tout ou rien ne m’intéresse pas, car je vais chercher la balise avec un portatif UHF en FM comme par exemple à l'aide mon récepteur de radiosonde (<a href="https://f4egx.blogspot.fr/2011/03/desensibilisons-un-puxing-px-777-uhf.html">https://f4egx.blogspot.fr/2011/03/desensibilisons-un-puxing-px-777-uhf.html</a>)<br />
<br />
Elle va émettre constamment. Attention, il ne faudra pas mettre d'antenne performante sur la balise, car c'est uniquement en dessous de 1mW de p.a.r qu'on a le droit d'émettre constamment. Avec les 10 mW p.a.r. on ne doit pas dépasser un coefficient d’utilisation de 10%.<br />
<br />
Il faut donc moduler en FM l'indicatif de la balise. Le signal BF proviendra d'un arduino. <br />
Je vais jouer sur le quartz 13,560MHz, avec une varicap. Je sors mes fonds de tiroirs.<br />

<br />
J'ai un bout d'une vieille sangle, ça fera l'affaire. Et un petit coup d'<a href="http://www.openscad.org/" target="_blank">Openscad</a> et hop. <br />
<br />
J'ai imprimé deux pièces en PLA pour mon K2. J'ai mis les fichiers à disposition sur thinkiverse.<br />
<a href="http://www.thingiverse.com/thing:1497454">http://www.thingiverse.com/thing:1497454</a><br />
<br />
<a name='more'></a><br />
Il faut que la sangle ne soit pas trop épaisse (1mm max) et la pièce a été prévue pour de la sangle de 26mm grand max.<br />
Pour la longueur, c'est à votre convenance.<br />
<br />
Avant de mettre la sangle entre la pièce imprimée et le poste, je l'ai préalablement préparée. La zone de la sangle qui sera sous la pièce imprimée a été traitée avec de la cyanoacrylate pour coller le maillage du tissus.<br />
Puis j'ai percé deux trous dans la sangle, dans cette zone au fer à souder, à basse température. Les vapeurs de cyanoacrylate ne sont pas agréable (toxiques), ne les respirez pas!<br />
<br />

<tr><td class="tr-caption" style="text-align: center;">La zone qui va être percée au fer à soudée, a été traitée à la cyanoacrylate pour tenir les fibres de la sangle</td></tr>
</tbody></table>
<br />
<br />
Les vis sont du M3, mais la pièce est prévue pour du M4.<br />
Ne pas oublier de coller l'écrou qui sera dans le poste: si ça se dévisse, attention aux court-circuits! J'ai simplement bloqué avec de la colle chaude.<br />
<br />

I do not want to be dependent on a PC or a smartphone to learn Morse code. There with this electronic assembly, I have it in the pocket, I turn ON and the exercise is directly available.<br />
<div>
I thought it was much more convenient to me, to make a little Arduino board to learning CW with ajust speed capabilities. The Morse tutor Kit by Dan M0TGN is perfect for that!<br />
<div style="text-align: left;">
</div>
<br />
I discovered the wonderful book by Carlo IK0YGJ. It is for this reason that there is no display, because we use the book to learn Morse code.<br />

I modified the Arduino M0TGN program so that the Arduino send exercises Morse code of the book . The main difficulty was that all exercises fit into is in Arduino.<br />
Thank to Fred F1UIH helped me. We discovered the use of PROGMEM, and its reading method "pgm_read_byte_near"!</div>

<span class="" style="cursor: auto; margin: 0px; padding: 1px 0px;">Après quelques jours à la base Port-aux-Français, je vais probablement marcher 30km à pied, jusqu'à la cabane de Cap Ratmanoff. </span></div>

<span class="" style="cursor: auto; margin: 0px; padding: 1px 0px;">Mon activité radioamateur sera secondaire par rapport au travail scientifique.</span></div>
<div class="" id="magicdomid44" style="font-family: Arial, sans-serif; font-size: 12px; line-height: 16px; margin: 0px; padding: 0px; white-space: pre-wrap;">
<span class="" style="cursor: auto; margin: 0px; padding: 1px 0px;">Pour avoir une petite idée des conditions, et du trafic radio, je vais être isolé durant des semaines avec uniquement une vacation radio VHF journalière et non radioamateur avec la base Port-Aux-Français.</span></div>
<div class="" id="magicdomid45" style="font-family: Arial, sans-serif; font-size: 12px; line-height: 16px; margin: 0px; padding: 0px; white-space: pre-wrap;">
<span class="" style="cursor: auto; margin: 0px; padding: 1px 0px;">FT4XU est principalement activé pour donner de nos nouvelles à mes amis radioamateurs tout autour du monde, dans l'esprit "si tous les gars du monde" :) Il n'est pas prévu de faire des QSO du style contest.</span></div>
<div class="" id="magicdomid46" style="font-family: Arial, sans-serif; font-size: 12px; line-height: 16px; margin: 0px; padding: 0px; white-space: pre-wrap;">
<span class="" style="cursor: auto; margin: 0px; padding: 1px 0px;">Dans la cabane, je vais vivre avec d'autres personnes dans un espace confiné et mes collègues n'ont probablement aucune connaissance de ce loisir. Ils vont surement devoir endurer le bruit du poste de radio et ce bruit est une source potentielle de dérangement après une longue et difficile journée de travail.</span></div>
<div class="" id="magicdomid47" style="font-family: Arial, sans-serif; font-size: 12px; line-height: 16px; margin: 0px; padding: 0px; white-space: pre-wrap;">
<span class="" style="cursor: auto; margin: 0px; padding: 1px 0px;">J'ai l'espoir d'avoir l'opportunité de présenter à mes collègues, le meilleur du radioamateurisme, avec d'agréables conversations avec des radioamateurs sympathiques mais disciplinés.</span></div>

Malgré que mon anglais ne soit pas particulièrement bon, j'ai de très bons souvenirs d'excellent long QSO avec l'Australie, la Nouvelle-Zélande et l'archipel de Crozet lorsque j'étais FT5YI en 2008. Je reproduirai ce schéma, mais mes conditions de trafic seront largement plus difficiles.</div>

<span class="" style="cursor: auto; margin: 0px; padding: 1px 0px;">Mes conditions de trafic seront: un FT857, 50W, avec un dipole installé à hauteur d'homme, et une alimentation sur batterie 12V. Le log sera sur papier, il n'y aura pas de PC prévu pour le log. </span></div>

<div class="" id="magicdomid2" style="margin: 0px; padding: 0px;">
<span class="" style="cursor: auto; margin: 0px; padding: 1px 0px;">My work will bring me to south hemisphere for a scientific mission at Ratmanoff, 30km northeast of Port-aux-Français, Kerguelen archipelago .</span></div>
<div class="" id="magicdomid3" style="margin: 0px; padding: 0px;">
<span class="" style="cursor: auto; margin: 0px; padding: 1px 0px;">My scientist job is to maintain measuring instruments whose electronics works in very rough conditions and to prepare equiment requirement for future missions. </span></div>
<div class="" id="magicdomid4" style="margin: 0px; padding: 0px;">
<span class="" style="cursor: auto; margin: 0px; padding: 1px 0px;">In the same time, I will also studies king penguins with colleagues and help them in their work.</span></div>
<div class="" id="magicdomid5" style="margin: 0px; padding: 0px;">
<br style="margin: 0px; padding: 0px;" /></div>
<div class="" id="magicdomid6" style="margin: 0px; padding: 0px;">
<span class="" style="cursor: auto; margin: 0px; padding: 1px 0px;">I will leave France at mid-November to Réunion Island, and there get on board of "Marion Dufresne", the supply ship of the french austral territories. It will take approximately 10-15 day to reach the Kerguelen archipelago with a stopover at Crozet archipelago. After few days at Port-Aux-Français station, I'll have to probably walk 30km to the shelter at Cap Ratmanoff, carrying my stuff on the back with heavy rain and strong wind. That is why I will try to travel as light as possible.</span></div>
<div class="" id="magicdomid7" style="margin: 0px; padding: 0px;">

<div class="" id="magicdomid8" style="margin: 0px; padding: 0px;">
<span class="" style="cursor: auto; margin: 0px; padding: 1px 0px;">About my hamradio activities: They will be secondary to scientific work.</span></div>
<div class="" id="magicdomid9" style="margin: 0px; padding: 0px;">
<span class="" style="cursor: auto; margin: 0px; padding: 1px 0px;">To give a little idea of this activity, I will be isolated for weeks with only daily local marine-VHF non-ham radio-communications with the Port-Aux-Français base. </span></div>
<div class="" id="magicdomid10" style="margin: 0px; padding: 0px;">
<span class="" style="cursor: auto; margin: 0px; padding: 1px 0px;">FT4XU is primary to give somes news to hamradio friends around the world, like ham-spirit. :) It's not intended for contest-QSO style.</span></div>
<div class="" id="magicdomid11" style="margin: 0px; padding: 0px;">
<span class="" style="cursor: auto; margin: 0px; padding: 1px 0px;">At the shelter, I will live with other persons in a confined space and my colleagues will have probably no knowledge about this hobby. They will maybe have to endure the traffic audio noise and this noise will be a potentially disturbance for them after a long and harsh working day.</span></div>
<div class="" id="magicdomid12" style="margin: 0px; padding: 0px;">
<span class="" style="cursor: auto; margin: 0px; padding: 1px 0px;">I hope to have the opportunity to present to my colleagues the best of hamradio as a pleasant communication, with friendly but disciplined OM.</span></div>
<div class="" id="magicdomid13" style="margin: 0px; padding: 0px;">
<span class="" style="cursor: auto; margin: 0px; padding: 1px 0px;">Although my English is not particularly good, but I had nice memories of some great long QSO with Australia, New zealand and Crozet Island when I was in Antarctica as FT5YI in 2008. I want to replicate this scheme, but my working conditions will be even more difficult.</span></div>

<div class="" id="magicdomid15" style="margin: 0px; padding: 0px;">
<span class="" style="cursor: auto; margin: 0px; padding: 1px 0px;">My working conditions will be : FT857, 50W and a dipole antenna which can only be installed at human height, battery powered. There will be no PC for logging, only paper log. Logs won't be sent while activity because of no internet connection.Our camp will have no electricity, so i will have to work with batteries. They will be charged with solar energy when not needed by the scientific work.</span></div>
<div class="" id="magicdomid16" style="margin: 0px; padding: 0px;">

<div class="" id="magicdomid17" style="margin: 0px; padding: 0px;">
<span class="" style="cursor: auto; margin: 0px; padding: 1px 0px;">QSLing: I will give my log to Jean-Luc / F1ULQ who will handle cards AFTER I come back, don't ask for correction before. QSL card will be designed with travel photos and printed AFTER also. As I'm not member of national bureau, only direct exchange will be possible.</span></div>
<div class="" id="magicdomid18" style="margin: 0px; padding: 0px;">
<span class="" style="cursor: auto; margin: 0px; padding: 1px 0px;">Sked: It will not be possible to organize skeds: My only way to contact the world is my hamradio equipment. No internet or no phone connection. </span></div>
<div class="" id="magicdomid19" style="margin: 0px; padding: 0px;">
<span class="" style="cursor: auto; margin: 0px; padding: 1px 0px;">Band operations: don't ask for specific bands, there will be no low bands or magic band activity. I can not carry a lot of material. For weight and volume reasons, I have to take only the minimum and necessary equipment.</span></div>

Vélux qui reste alors ouvert lorsqu'il pleut dehors.</div>

Vu qu'il est ouvert, ça aère, c'est chouette le bon air frais! </div>

Mais alors il pleut aussi sur mes pauvres bouquins (d'histoire de marins?)...</div>

<br /></div>
<div>
Faut que je me rappelle lorsque je sors de la maison qu'il faut que je ferme ce *$#%§ ! de vélux.</div>
<div>
Un truc pratique, genre une led qui clignote est suffisant, et qui fonctionne à pile.</div>
<div>
<a name='more'></a><br /></div>
<h4>
Le capteur</h4>
<div>
J'ai installé un interrupteur à lame souple (ILS, magnet switch) sur mon vélux (ce n'est pas le plus compliqué). </div>
<div>
Quand la fenêtre est fermée, l'aimant est proche, l'interrupteur se ferme.</div>

<div>
<br /></div>
<div>
<br /></div>
<div>
<br /></div>
<div>
J'ai donc fait chauffer mon fer à souder.</div>
<div>
<br /></div>
<h4>
La commande</h4>
<div>
Première étape, il faut que le montage consomme le moins possible au repos (switch fermé).</div>
<div>
La seule solution est d'utiliser un montage avec une résistance de valeur la plus grande possible.</div>
<div>
4,7MOhm est largement suffisant (sous 5V, ça fait en gros dans les environ de 1µA).</div>
<div>
Un mosfet est recommandé, car il n'y a aucun courant qui circule dans la gate. J'avais un IRF540 sous la main.</div>
<div>
Les diodes et la résistance de 10k sont là pour protéger le montage.</div>
<div>
<br /></div>
<div>
Quand la fenêtre s'ouvre, le switch s'ouvre. La gate se retrouve à VCC, ce qui fait conduire le mosfet. C (le signal de Commande) se retrouve à la masse.</div>

<div>
A ce moment là le multivibrateur à transistors se met à fonctionner.</div>
<div class="separator" style="clear: both; text-align: center;">
</div>
<div>
<br /></div>
<h4>
L'oscillateur</h4>
<div>
J'ai choisi des capacités de faibles valeurs, 100nF, histoire de ne pas gaspiller trop d'énergie à les charger/décharger.</div>
<div>
Pour garder un clignotement visible, il faut forcément que le couple R*C soit raisonnable: hop 2,2MOhm (F=1/(0.7*2(2,2M*100nF))=3Hz). </div>
<div>
Il ne faut pas trop pinailler, la fréquence est dépendante de l'alim, et des doigts qui traînent sur le montage.<br />
J'utilise des transistors bipolaires d'utilisation courantes, mais avec un grand bêta (stature avec peu de courant dans sa base) : des BC549.</div>

<div>
<br /></div>
<h4>
La Led</h4>
<div>
La led que j'ai choisie est une HLP-CM1A-450DD. Je l'aime bien, elle est verte et extrêmement lumineuse. Mais surtout avec très très peu de courant, 100µA, elle s'allume avec la même intensité lumineuse qu'une vulgaire led verte à 20mA. </div>
<div>
Je vous invite à regarder sa datasheet <a href="http://www.avagotech.com/docs/AV02-2228EN" rel="nofollow" target="_blank">http://www.avagotech.com/docs/AV02-2228EN</a></div>

Je me suis fait peur: un petit court-circuit et un fil s'est dessoudé par la chaleur. J'ai bien compris qu'il ne fallait pas faire le malin! Dès que je peux, je coupe tout ce qui dépasse. C'est vraiment dangereux!</div>

La partie gestion de l'énergie, avec des voyants à LED indiquant le niveau de charge. Dans mon cas toutes les leds étaient éteintes, ce qui n'est pas de bonne augure... On voit aussi les deux fils pour la thermistance pour le controle de température. Et une bonne nappe souple qui va au connecteur se branchant sur le PC portable.<br />

Et le pire c'est que ça marche! Je vais voir dans l'avenir quelle autonomie j'ai avec ces accu de récup.<br />
Mais d'abord il faudra les charger. On trouve très facilement des chargeur pour des 18650 sur ebay, et pour pas cher du tout.<br />Je conseille quand même d’être toujours à coté du chargeur, pour des raisons de sécurité, si ça se passe mal.<br />
Quand ça se passe mal, ça a tendance à faire des belles flammes, alors attention!<br />
Bon hack!<br />

I connect the 2 jack wire (orange-RIGHT, white-LEFT), on the input pad of the pot, with 2x100nF X7R.<br />
The GND bluetooth module is soldered closest to ground power supply of the penguin circuit, to limit interfering noise.<br />

L'une en utilisant la prise de charge sur le côté du poste. Le poste est alors immobilisé.<br />
L'autre en enlevant l'accu et en le plaçant sur le socle de charge. Dans cette seconde option, pendant que l'accu déchargé se charge tranquillement sur son socle, il est alors possible de mettre un accu chargé dans le poste. De cette façon on peut continuer à se servir du poste.<br />
<br />
Voici une petite modification du socle de charge de l'UV3R, qui assez curieusement est une boite vide...<br />

Si on ouvre le socle de charge de l'UV3R on constate qu'il ne contient aucune électronique.<br />
Or se socle se branche directement sur une alimentation 5V. Il n'y a alors aucun contrôle de charge. Ce n'est pas génial pour la lipo.<br />

J'ai donc décidé de mettre un petit circuit dans le socle du chargeur.<br />
J'ai choisi d'utiliser un MCP73812t qui coute bien moins d'un euro.<br />

Il est dispo chez Farnell (novembre 2012).<br />
<a href="http://fr.farnell.com/microchip/mcp73812t-420i-ot/ic-li-ion-li-poly-charger-sot23/dp/1627187">http://fr.farnell.com/microchip/mcp73812t-420i-ot/ic-li-ion-li-poly-charger-sot23/dp/1627187</a><br />
Sa datasheet est ici: <a href="http://www.farnell.com/datasheets/77596.pdf">http://www.farnell.com/datasheets/77596.pdf</a><br />
<br />
Il suffit simplement de suivre la datasheet et ce montage fonctionne super bien.<br />
Le courant est à 200mA en début de charge pour un accu très déchargé (sous sa limite de sécurité), pour atteindre 450mA en fin de charge.<br />
Une fois l'accu chargé à 4,2V, le courant de charge tombe à 0mA et des poussières.<br />
<br />
Vu que dans l'UV3R ce sont des accu de 1500mA, la charge à 450mA devrait se faire en moins de 4h. En toute sécurité et sans s'occuper de rien.<br />

J'ai fait un montage à l'ugly comme j'aime les faire, que j'ai protégé avec de la gaine thermorétractable.</div>
<div class="separator" style="clear: both; text-align: left;">
Au centre du circuit imprimé, prendre un foret de 6mm et l'utiliser à la main pour enlever une pastille.</div>

A cet endroit le composant actif sera collé avec de la colle cyanoacrylate. </div>
<div class="separator" style="clear: both; text-align: left;">
En prenant du brin d'un fil électrique multibrin on relie la patte du compostant sur une des pastilles d'un circuit à prototypage. C'est la manip la plus difficile.</div>
<div class="separator" style="clear: both; text-align: left;">
La résistance de 2k est dans son format standard pour relier la patte 2 à la 5.</div>
<div class="separator" style="clear: both; text-align: left;">
Les condensateurs de 1uF 25V sont en céramique cms 0805. Chaque extrémité du condensateur étant sur une pastille différente. Aucune difficulté à souder!</div>

En effet, quand on est dans une pièce calme, en VHF/UHF c'est quand même un peu fort, même le volume au minimum.<br />
<br />
Cette modif n'est pas compatible avec une utilisation dans un environnement bruyant telle une rue de ville bien fréquentée, car vous n'entendrez plus rien. Elle adapte votre poste pour l'utilisation dans une pièce calme ou en pleine nature pour éviter de déranger. En fait le problème c'est que la plage de réglage du poste en du "bouton volume" n'est pas assez importante.<br />
<br />
<b>Pour avoir une idée: </b><br />
<b>Avec bouton volume au minimum avant modif on aura l'équivalent avec le </b><b>volume à fond après modif !</b><br />

<br />
Nous allons toucher au niveau BF de la VHF et de l'UHF et également le niveau BF de la partie radio FM. Ce n'est pas compliqué, juste des ajustements de résistances cms 0402 (1mm de long, ça paaaaaasse).<br />
<br />
Voyons où cela se passe sur le circuit.<br />
Une fois l' UV3R délicatement ouvert, on peut observer que la structure de l'implantation des composants de ce poste est relativement facile à analyser.<br />
A droite, tout l'étage radio qui commence en haut, à la prise antenne, les filtrages, les commut par diodes, puis les étages de puissance, et en bas, la puce radio V-UHF.<br />
<br />
<h4>
Atténuation de la partie audio</h4>
<div>
Il y a beaucoup trop de gain sur l'ampli audio LM4890:</div>
<div>
A l'origine:</div>
<div>
R43=2k (la plus proche du circuit intégré)</div>
<div>
R15=100k (entre les deux condensateurs)</div>
<div>
<br /></div>
<div>
J'ai modifié la valeur de ces résistances, comme noté dans la datasheet du LM4890:</div>
<div>
R43=R15=22k</div>
<div>
<br /></div>
<div>
<br /></div>
<div class="separator" style="clear: both; text-align: center;">
<a href="http://1.bp.blogspot.com/-C47RRrp3HwU/UGSo6kyUVHI/AAAAAAAAFMI/z24MfYPFJoM/s1600/Photos-1077web.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="256" src="http://1.bp.blogspot.com/-C47RRrp3HwU/UGSo6kyUVHI/AAAAAAAAFMI/z24MfYPFJoM/s320/Photos-1077web.jpg" width="320" /></a></div>
<div class="separator" style="clear: both; text-align: center;">
<br /></div>
<div class="separator" style="clear: both; text-align: center;">
<br /></div>
<h4>
Augmentation du gain en FM</h4>
<div class="separator" style="clear: both; text-align: left;">
Bon, vu qu'on a baissé le niveau général de la BF (et du retour de la tonalité 1750Hz), la partie radio-FM est un peu faible maintenant.</div>
<div class="separator" style="clear: both; text-align: left;">
</div>
<div class="separator" style="clear: both;">
Voyons alors du côté du RDA5802, le chip récepteur FM.</div>
<div>
A l'origine R50=R51=15k, permet de faire le mélange stéréo vers mono.</div>
<br />
<div class="separator" style="clear: both; text-align: left;">
D'après sa datasheet, la sortie du RDA5802 supporte une charge de 32 Ohm, on pourrait presque y mettre un casque!</div>
<div class="separator" style="clear: both; text-align: left;">
En modifiant R50=R51=4,7k l'audio des stations radio FM est bien confortable pour les "chaines nationales". Sinon cela dépend surtout de votre radio FM préférée qui a tendance à sur-compresser la dynamique audio de son émission. A vous de voir. ;)</div>

Le lapin de Pâques est futé, il ne se laisse pas approcher, d'ailleurs qui l'a déjà vu?<br />
Seul quelques traces au sol part-ci part-là. Des petits oeufs sont semés tout le long de son trajet.<br />
C'est parce qu'il est très rapide, et fait des bons gigantesques, et quelques chocolats tombent de son panier.<br />
<br />
Pour éviter des collisions, le lapin s'est acheté une balise.<br />
Nous pouvons l'entendre sur 144.603MHz SSB, elle fait 0dBm!<br />

On peut estimer l'état de la pile indirectement.<br />
Le silence entre chaque émission à été mesuré à 23°C (il est possible que la température influe également, mais avec un peu de bon sens, on devrait retrouver ses billes).<br />

la balise aura fonctionné presque 2 mois.<br />
Maintenant il faut la récupérer!<br />
<br />

MAJ 22/05/2012<br />
Pourquoi la balise s'est brusquement arrêtée?<br />
La pile lithium récupérée n'était pas neuve, elle provenait d'un stock en vrac. Il est donc possible qu'elle était déjà utilisée avant mon utilisation. Bon c'est pas grave, la balise a fonctionné suffisamment longtemps pour le petit jeu de chasse au renard avec les copains radioamateurs.<br />
Mais lors de sa douce décharge en fonctionnement normal, un phénomène s'est produit et a donc accéléré sa décharge:<br />
Lorsque la pile lithium se décharge, sa résistance interne série augmente. Lorsque la balise se met en émission, elle consomme 4mA ce qui implique une chute de tension au borne de la résistance série de la pile. Du coup, nous n'avons plus assez de tension pour alimenter correctement le microcontroleur qui se met alors en RESET. Le RESET, du microcontroleur, éteint la balise. Comme la balise s'éteint, on n'a plus de consommation, donc plus de chute de tension au niveau de la pile. L'alimentation est de nouveau correcte, donc le soft du microcontroleur redémarre ce qui met la balise en émission (TX). TX qui provoque le reset etc...<br />
En définitive, la balise se met à émettre des bips de plus en plus court et rapproché, jusqu'à épuisement de l'énergie. Aucune idée sur la durée de phénomène, mais ça peut être utile pour prévenir d'une mort imminente de la balise.<br />

<div class="separator" style="clear: both; text-align: left;">

Voilà le soft Arduino pour avoir le RSSI audio.<br />
Il permet de générer des beeps courts de tonalités plus ou moins éleve en fonction de la force du signal et cela plusieurs fois par seconde.<br />

Sur le Puxing, j'ai relié l'entrée validation (PIN 3 ) sur le bouton d'ouverture de squelch.<br />
Quand on appuie sur le bouton, on met cette entrée à la masse, via une diode 1N4148. Apparemment il n'a pas été nécessaire de mettre une résistance de tirage.<br />
<br />
La PIN 6, tone OUT, est reliée sur le potard audio côté injection de signal (ni à la masse, ni sur la broche du milieu du potard), via une résistance entre 1k à 10k en fonction du niveau audio voulut.<br />
<br />
Le signal RSSI est directement relié à l'entrée RSSI (PIN 2)<br />
<br />
L'alimentation est prélevée sur l'alim 5V du uC à proximité. (cf photo)<br />
<br />
La masse est prise sur le plan de masse.<br />

</div>
<div class="separator" style="clear: both; text-align: left;">
</div>
<div class="separator" style="clear: both; text-align: left;">
It's very easy to build a geiger counter from various parts.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
A Geiger counter consists of a power supply, a tube containing a gas that ionizes when a particle passes through it and a speakeror even a galvanometer.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
The first thing to do is to buy a Geiger tube. Do not try to make one.</div>
<div class="separator" style="clear: both; text-align: left;">
<span class="Apple-style-span" style="font-size: large;"><b><br /></b></span></div>
<div class="separator" style="clear: both; text-align: left;">
The main difficulty is that we must supply it with "high voltage".</div>
<div class="separator" style="clear: both; text-align: left;">
To resolve this problem, I bought EL-Wire.</div>
<div class="separator" style="clear: both; text-align: left;">
http://en.wikipedia.org/wiki/Electroluminescent_wire</div>
<div class="separator" style="clear: both; text-align: left;">
Electroluminescent wire (often abbreviated to EL wire) is a thin copper wire coated in a phosphor which glows when an alternating current is applied to it.</div>
<div class="separator" style="clear: both; text-align: center;">

<div class="separator" style="clear: both; text-align: left;">
<span class="Apple-style-span" style="font-size: large;"><b>The first step!</b></span></div>
<div class="separator" style="clear: both; text-align: left;">
On ebay, we can find a EL-wire for under 10€, and it works with two batteries of 1.5 V = 3V!</div>
<div class="separator" style="clear: both; text-align: left;">
With 3V EL-Wire power supply, we are left with 125Vac 1kHz output (remove EL-Wire).</div>
<div class="separator" style="clear: both; text-align: left;">
There remains to add a Dickson multiplier (parallel capacitor voltage multiplier)</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
With the tube that I bought, I need 700V (it's a 6107/bs212 tube).</div>
<div class="separator" style="clear: both; text-align: left;">
The diagram below is enough and easy to build. (Blue: EL-Wire power supply, black: Dickson multiplier)</div>

<br />
<br />
I was advised on my tube, the power to 500V. So I added a 10Meg resistor to load the output of my power supply. I am now below the 650V.<br />
To test my geiger tube, I first started looking at the pulses with an oscilloscope to the legs of the resistance of 10M connected to the case of Geiger tube.<br />
Then I connected a Piezo speaker with resistor 1k.<br />
We hear many clicks! ;) About 5 clicks per minute! The background noise!<br />
It's not a good idea to connect a piezo speaker direct to 10Meg that prematurely ages the tube.<br />
<br />
<br />
<br />
<span class="Apple-style-span" style="font-size: large;"><b>Add an Arduino!</b></span><br />
I remove le piezo speaker and add piezo buzzer and arduino mini pro ATmega168 16MHz.<br />
Now the arduino is programmed as a monostable.<br />
Each ionization, a 50ms beep is emitted.<br />

J'ai donc acheté chez Lextronic une alimentation ajustable Velleman de 3V à 12V pour pouvoir la modifier à la tension dont j'ai besoin. Le problème c'est quelle ne propose pas du 3,3V mais du 3V ou du 4,5V voire plus!<br />
Pour faire une modification de cette alimentation la plus simple, et donc affiner le réglage la tension d'alimentation comme on veut sans trop se casser la tête, le mieux c'est d'avoir une alimentation avec un sélecteur de tension d'origine: Le pont de résistance de régulation sera alors très simple à trouver!<br />

</div><div class="separator" style="clear: both; text-align: left;">Le but du jeu est de modifier la valeur d'une résistance pour pouvoir avoir du 3,3V.

R2 reste fixe. </div><div class="separator" style="clear: both; text-align: left;">VCC est la sortie de l'alim, c'est donc la tension qui est palpée.</div><div class="separator" style="clear: both; text-align: left;">Vout la valeur qui rentre dans le circuit de régulation et qui donc va servir à ajuster le découpage de l'alim et donc ajuster la tension VCC à travers d'un circuit intermédiaire:</div><div class="separator" style="clear: both; text-align: left;">Plus Vout est grand, plus l'alimentation baisse la valeur de VCC.</div><div class="separator" style="clear: both; text-align: left;">Plus Vout est petit, plus elle augmente VCC. C'est comme ça que se régule la tension de l'alimentation. Car l'alimentation cherchera toujours à avoir la même valeur pour Vout! Et pour jouer avec Vout, il faut qu'elle ajuste VCC.</div><div class="separator" style="clear: both; text-align: left;"><br />
</div><div class="separator" style="clear: both; text-align: left;">Et donc plus R1 sera faible plus Vout sera grand. Et avec la contre-réaction, et bien VCC va baisser. Bingo!</div><div class="separator" style="clear: both; text-align: left;"><br />
</div><div class="separator" style="clear: both; text-align: left;">La première chose à faire est d'enlever le commutateur et les résistances qui sont commutées.</div><div class="separator" style="clear: both; text-align: left;">On peut s'aider de la sérigraphie sur le PCB côté soudure. Enlever S1, R14, R13, R15,et R16</div><div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/-saaHU0EHNEE/TigmhWAHLhI/AAAAAAAACuA/as3HPffpTUc/s1600/Photos-0162.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="256" src="http://1.bp.blogspot.com/-saaHU0EHNEE/TigmhWAHLhI/AAAAAAAACuA/as3HPffpTUc/s320/Photos-0162.jpg" width="320" /></a></div><div class="separator" style="clear: both; text-align: left;"><br />

</div><div class="separator" style="clear: both; text-align: left;"><br />
</div><div class="separator" style="clear: both; text-align: left;">On va mettre notre propre résistance.</div><div class="separator" style="clear: both; text-align: left;">Avec cette alim, il a été très facile de trouver la valeur: il faut du 3,6k pour avoir du 3,3V.</div><div class="separator" style="clear: both; text-align: center;"><a href="http://4.bp.blogspot.com/-pMOYi2FmnYQ/TigmisVmmFI/AAAAAAAACvE/CS8nY2BK11U/s1600/Photos-0153.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="256" src="http://4.bp.blogspot.com/-pMOYi2FmnYQ/TigmisVmmFI/AAAAAAAACvE/CS8nY2BK11U/s320/Photos-0153.jpg" width="320" /></a></div><div class="separator" style="clear: both; text-align: left;"><br />
</div><div class="separator" style="clear: both; text-align: center;"></div><div class="separator" style="clear: both; text-align: left;">Et cette résistance de 3,6k la souder sur l'une des pastille sous la sérigraphie S1 (visible côté soudure) et sur la piste commune de toutes les résistances qu'on a enlevé. ça devrait même rentrer pile poil ;)</div><div class="separator" style="clear: both; text-align: left;"><br />
</div><div class="separator" style="clear: both; text-align: left;">Et voilà le tour est joué. Il n'y a plus qu'à fermer le boitier et vérifier si la tension est correcte.</div><div class="separator" style="clear: both; text-align: left;"><br />
</div><div class="separator" style="clear: both; text-align: left;">J'ai effectué cette modification sur 3 alimentations identique de cette marque, c'est reproductible sans problèmes, et en 10mn c'est fait! Pour des alimentations ayant un autre référence ou une autre marque, il faudra réajuster la valeur.</div><div class="separator" style="clear: both; text-align: left;">Et rien n'empêche de faire cette modification pour d'autres valeurs, par exemple une résistance de <b>14k pour faire du 5V</b>.</div><div class="separator" style="clear: both; text-align: left;"><br />
</div><div class="separator" style="clear: both; text-align: center;"><a href="http://1.bp.blogspot.com/-PmhEuRUjLww/TilGIdSIL5I/AAAAAAAACvk/oMqAqLnforg/s1600/Photos-0163.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="203" src="http://1.bp.blogspot.com/-PmhEuRUjLww/TilGIdSIL5I/AAAAAAAACvk/oMqAqLnforg/s320/Photos-0163.jpg" width="320" /></a></div><div class="separator" style="clear: both; text-align: center;">Une association de résistance pour faire 14k Ohm, et donc avoir une sortie 5V</div><div class="separator" style="clear: both; text-align: left;"><br />

Histoire de balises</i></span><br />
<br />
Ce matin, comme il fait beau et que j'avais un peu de temps libre je me suis permis une petite sortie sympathique, à la recherche du lapin de Pâques. Plutôt sa balise...<br />
<br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://titley-scientific.com/images/pic-one-stage-transmitter-01.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://titley-scientific.com/images/pic-one-stage-transmitter-01.png" /></a></div><div style="text-align: center;"><span class="Apple-style-span" style="font-size: x-small;"><i>Les balises VHF pour du <span id="goog_53130243"></span><a href="http://www.biotrack.co.uk/tagchooser.php">radiotracking</a><span id="goog_53130244"></span> sont dans la bande 148-152MHz.</i></span></div><div style="text-align: center;"><span class="Apple-style-span" style="font-size: x-small;"><i>Elles envoient à peut-près une pulse de 30ms toutes les secondes.</i></span></div><div style="text-align: center;"><span class="Apple-style-span" style="font-size: x-small;"><i>La puissance est de l'ordre (inférieur) du milliwatt.</i></span></div><br />
<a name='more'></a><br />
<br />
Pourquoi? bien simplement parce que Luc <a href="http://lpistor.chez-alice.fr/">F6BQU</a>, m'avait dit qu'il entendait chez lui cette fameuse balise de lapin de Pâques. A bon? Elle s'entend apparemment à plus de 15km? Vraiment curieux, d'habitude c'est de l'ordre de 2 à 5km!<br />
"Oui Nicolas, me dit-il l'autre jour, je l'entends sur 148.740 en CW. Et j'ai compté, il y a 48 pulses par minute."<br />
Curieux, la balise dite du Lapin de Pâques se trouve sur 743... Bon disons que c'est la même, c'est à cause d'une dérive en températures etc...<br />
<br />
Jeudi 21 avril 2011 au petit matin en allant au boulot, je m'arrête en voiture sur un bas côté. Je suis assez proche de la balise 743, pour écouter. J'ai compté 62-64 pulses par minute (je ne sais pas compter au delà de 10...)<br />
Donc de forts soupçons commençait à m'envahir la 743 que j'entendais, n'était surement pas la 740 que Luc entendait.<br />
<br />
<span class="Apple-style-span" style="font-size: large;"><i>2. La chasse</i></span><br />
Donc ce vendredi matin, FT817 et une HB9CV 144MHz sous le coude, un VX-7R pour contacter les copains, je pris les chemins de campagnes. Charles F1TZV était là pour me seconder à la radio en cas de besoin.<br />
<br />
<b>2.a</b> premier point sur <a href="http://goo.gl/maps/oRGv">le point haut le plus proche, la colline de Mittelhausbergen</a> le plus proche du QRA.<br />
J'entends bien la balise du lapin de Pâques (743), mais rien de la 740.<br />
Bon je vais me diriger un peu plus à l'ouest.<br />
<br />
<b>2.b </b>deuxième point, toujours sur la <a href="http://goo.gl/maps/CAKD">hauteur de Neugartheim-Ittlenheim</a>, à proximité d'un <a href="http://upload.wikimedia.org/wikipedia/commons/6/67/Neugartheim-Ittlenheim_tour_Chappe.jpg">télégraphe chappe</a>.<br />
Haaaa, j'entends la balise 743, 13km et bien mon lapin, t'es fichu! La direction donnée est bien du côté de Strasbourg. C'est ok<br />
Maintenant voyons voir sur 740. ha? Tiens! En voilà une deuxième... C'est malin, voilà deux lapins... Je l'entends vers le SUD-EST. Je préviens les copains. Marc F6GRH tente de l'écouter en FM. Fabrice <a href="http://f4avi.homelinux.net/">F4AVI</a> l'entend faiblement chez lui en SSB.<br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://upload.wikimedia.org/wikipedia/commons/6/67/Neugartheim-Ittlenheim_tour_Chappe.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="http://upload.wikimedia.org/wikipedia/commons/6/67/Neugartheim-Ittlenheim_tour_Chappe.jpg" width="240" /></a></div><br />
<br />
<br />
<b>2.c</b> Je me dirige vers la colline de Nordheim au sud-ouest, célèbre pour son émetteur de télévisions. Mince <a href="http://goo.gl/maps/hSlz">le coin</a> est plein de vignes... C'est embêtant pour faire de la gonio...<br />
Mais j'entends plutôt bien la 743, et je pointe encore la 740 sur le SUD-EST.<br />
<div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/-uvAHvsrCGc4/TbGINEAGrII/AAAAAAAACcY/T1KdYwa3gl4/s1600/Capture.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="186" src="http://3.bp.blogspot.com/-uvAHvsrCGc4/TbGINEAGrII/AAAAAAAACcY/T1KdYwa3gl4/s320/Capture.png" width="320" /></a></div><br />
<br />
<b>2.d</b> Je vais aller plus au sud sur un <a href="http://goo.gl/maps/Dvtk">petit plateau</a> mince je n'entends rien... Bon je continue à me diriger vers Strasbourg...<br />
<br />
<b>2.e</b> Tiens un petit <a href="http://goo.gl/maps/dro2">point haut dégagé</a>... avec un pylône radio!<br />
Vite un point!<br />
Pas de nouvelle de la 743, mais la 740 se trouve plein Nord!<br />
Hop Direction plein Nord Ittenheim. J'espère que je vais savoir qui porte cette balise!<br />
<br />
<b>2.f</b> En entrant la Ittenheim, je me dis que je devrais mettre mon antenne omnidirectionnelle sur mon FT817, juste histoire de voir si la balise est "écoutable" en roulant. A un feu rouge, je fais en vitesse l'échange d'antenne. Wouah! plein pot! Je me dirige au <a href="http://goo.gl/maps/6P45">centre ville, vers la mairie</a>.<br />
Je baisse la sensibilité du FT817, il faut que j'entende le plus faiblement possible la balise pour pouvoir la chercher. Je pense qu'elle se trouve de l'autre côté du village.<br />
<br />
<br />
<span class="Apple-style-span" style="font-size: large;"><i>3. le signal est très fort!</i></span><br />
Je <a href="http://goo.gl/maps/BW9r">passe devant la mairie</a>!<br />
Tiens, le signal baisse... Non?<br />
Hop marche arrière! Oulà ben oui!<br />
Hop je prends une rue à droite, <a href="http://goo.gl/maps/s3mF">rue de la Mairie</a><br />
Le signal devient de plus en plus fort, même trop fort! Il est impossible de savoir d'où ça vient.<br />
Je me garde à proximité d'un <a href="http://goo.gl/maps/jVg2">coin de verdure</a>.<br />
Et je sors quand même ma HB9CV.<br />
<br />

<br />
Deux chats se prélassaient à l'ombre des buissons...<br />
Mais pas moyen de savoir sur qui se trouve cette balise.<br />
<br />
En discutant avec quelques personnes de passages, il parait que je suis dans une grande zone à <a href="http://www.hamster-alsace.fr/grand-hamster-dalsace-.html">Hamster d'Alsace</a> <span class="Apple-style-span" style="font-family: arial; font-size: x-small;"><img goomoji="gtalk.347" src="https://mail.google.com/mail/e/gtalk.347" style="cursor: move; margin-bottom: 0px; margin-top: 0px; vertical-align: middle;" /></span><span class="Apple-style-span" style="font-family: arial; font-size: x-small;"> </span>.<br />
