====DONE:====&lt;br /&gt;
* Arduino en arduino clones devboardjes programmeren werkend met laptop via arduino ide.&lt;br /&gt;
* 1 Arduino clone aangepast (condensator tussen reset en gnd, programmer sketch erop, kabeltjes naar breadboard) om als programmer te werken voor attiny en losse atmega chips. &lt;br /&gt;
* standalone ATTINY45 op 5V met de &amp;#039;blink sketch&amp;#039; geflashd via de clone programmer&lt;br /&gt;
* morsebaken sketch verder uitgewerkt en op de ATT45 gezet. LEDje knippert nu morseseinen&lt;br /&gt;
* ATTINY 45 op 3.3 V laten lopen zodat interface met HOPERF radiotjes geen gedoe geeft. (3V lithium knoopcel)&lt;br /&gt;
* ATTINY 45 getest met HOPERF radiotje in CW mode. Werkt verbazend goed met prima ontvangst door de hele gang van het gebouw tot op het parkeerterrein met het bakentje op een breadboardje in de klusbunker&lt;br /&gt;
* vossejachtbakentje gemaakt in een verrassingsei. Zie [[RadioEi]].&lt;br /&gt;
* Vervolg RadioEi: ATTINY en/of ATMEGA op 3.3 V interfacen met HOPERF radiotje zodat andere frequencies en modes  (e.g. rtty) gebruikt kunnen worden en hier mee testen: eerste tests zijn wat teleurstellend, minimale shift in FSK mode is erg groot, resolutie van de &amp;#039;werk-frequentie&amp;#039; lijkt ook erg grof te zijn. Moet wel mogelijk zijn om een aantal zendertjes elk op een eigen frequentie in OOK-modus te laten werken.&lt;br /&gt;
====TODO:====&lt;br /&gt;
* Vervolg [[RadioEi]]: verder testen met mogelijkheden HOPERF zendertje.&lt;br /&gt;
* als reference design Meurs Mk2 nabouwen op breadboard? [https://www.kickstarter.com/projects/1733068917/budget-high-altitude-balloon-photos-from-our-strat/posts/1110832?ref=backer_project_update kickstarter pagina] [https://github.com/97Pedrito/high-altitude-balloon code op github]&lt;br /&gt;
* Onderzoeken werkbaarheid seriele interface op ATT45/ATT85 &lt;br /&gt;
* GPS, radio, uController samenvoegen en aan baken software klussen om een pico baken te maken.&lt;br /&gt;
* programmer standalone (losse ATMEGA) en robuuster (doosje) maken zodat dev-bordje weer vrij komt&lt;/div&gt;</summary>
