Log from An Unfortunate SMD Project
As the misery spreads, it seems only fitting that we should recognize those who are unfortunate enough to suddenly complete the SMD Challenge. To be included in this club, you must submit photographic evidence (or link thereof) of a working SMD...

We're crowdfunding!
Log from uECG - small open source wireless ECG sensor
Finally we got to post on Hackaday! We're back from Makerfaire - it's been a very busy time. Lots of people (20+) tested our device in the field, so to say, and ironically, it could be considered a stress testing for our device, though we couldn't measure...

Write-up
Log from ESP32 Game Console
To be honest, i started this project because I did not want to pay about $80 for console and shipping to Czech Republic. If I look back, it cost me much much more, but it would not be such a fun & and some frustration. It took me about 1,5 year to finish...
