Heart Spark V2.0!

June 17, 2013mrericboyd No Comments »

I’ve finally managed to make more Heart Spark V2.0s! It’s been a lot more trouble than I anticipated – basically, I had some beginners luck with soldering the 0.4mm pitch pins on the ATTINY24, and once that luck ended, it took me a long time to get it working again. New paste, some layout changes, spending more money on better quality boards, and some new techniques – these were all required. Even so there is a tiny jumper on these new V2.0s, on the back – you can all marvel at my soldering skills :-). Anyway, if you wanted one from before, now is your chance – I have 12 for now, $79 each: Heart Spark V2.0 order page.
