    Pretty cool project, although I'm not sure why anyone would install this internally. Surely the Trinket M0 is a better fit for that since you won't be able to use the main feature of this, which is the battery.

    Awesome job, man. I'll be purchasing one from you via Tindie.

    Its built to be easy to install internally, if you want to install internal you would use the version without the battery backpack. It just boils down to using one or the other, they should perform the same, but yes m0 is more readily available and not limited quantity. It would probably be the preferred method in that case.

    Hey, nice to see you again! I have seen your build and it looks great. Is that a reset button glued at the top there? I was trying to figure it out, that's all I could come up with.

    Power button. Cuts voltage from positive Cr2032. I'm going to build another one this weekend and provide a tutorial perhaps a complete video tutorial from start to finish if I can get my wife, camera woman, to cooperate.

    Got it, thanks! I bet that video would be popular, I hope you get a chance to do it. Canna also had some pics of his project, we should make a thread for everyone's mods and DIY setups, it would be great for ppl to be able to see all the different ways that it can be set up. Even I've got a trinket soldered to a backpack that I could snap a shot of - pretty basic compared to yours, but it works!

    You want to start a thread to showcase everyones DIY builds? I've got a cheesy one I can post, and xeswitched has a much nicer one similar to what you did.. I would start the thread myself, but I'm busy messing with boards! :)

    I just put mine up - read it and weep, buddy! I had to solder BOTH of those wires myself, and learn how to use double sided tape without injuring myself - Boom!

    Pro-tip: Just don't grab the soldering iron by the shiny side, and you'll be off to a good start.

    Hmm, that seems quite high. I wonder if some power could be saved by disabling some of the systems of the SAMD21 that aren't needed for this process?

    For your LED, you could always just stick it on a PWM output and dim it that way so a hardware change isn't needed. Then the user could set the brightness to whatever they like when compiling the UF2 :D

    Supercaps are super rad for sure, but there are a lot of "gotchas" I wasn't previously aware of and a bunch of math involved I had to learn. It's definitely not the best solution for every project. It was fun for me but I'm a huge nerd. :P

    The cheapest I've found the DotStar-2020s at a legitimate dealer is $40/100 at Mouser which is quite expensive still. The APA-102 chip takes around 1-2mA at idle so I'd really like to ditch it. I found this little guy on LCSC (my new best friend) for dirt cheap:

    https://lcsc.com/product-detail/Light-Emitting-Diodes-LED_FM-B1515RGBA-HG_C113717.html

    It costs 3 cents in quantities of one and if you only want one color at a time, you can just put a single 660Ω resistor on the cathode and run it directly off of the output pins of the ATSAMD21. You might even be able to get away with 2 colors at a time at a slightly reduced brightness.

    But... so shiny...


    Ow.


    Worth it.
