Hi Guys and Girls,
I just wanted to show you my "quick and dirty" Payload-Dongle build.
It's mainly based on a trinketM0, which a got from Amazon, using an early version of the firmware provided by mattytrog and is powered by a 750 mAh LiPo-Battery (because I had them lying around); the pushbutton just connects the Vcc from the battery, so you have to keep it pressed for a few seconds until the payload was injected. I haven't come to around to adapt it to the current "multi-payload-firmware" with payload-selection.
I designed the housing using 'Siemens NX 10' (CAD/PLM-Software) and printed it on my 'Tevo Tarantula'... yeah, I know, it's much to large but it keeps the electronics safe and it's very hard to loose because of it's size
I don't use a "classic jig" but I've solder a reed-switch into my right JoyCon (sorry, didn't make pictures of that) which I find to be a very convenient way to enter RCM.
