How to be smart hardware programmer: hardware

That feeling when you see the magic smoke come out of your board and you don't have a spare.

LOL that's so right! I have to but several if I buy from ebay etc. The quality is not guaranteed. The only guarantee is buying more and testing them. Here is a tester I made to test out all arduino nano clones pins (analog and digital), RTC modules, SD card breakout boards, 10ODF boards, and ADC boards. Some of these boards are just bad. If I don't test and solder them somewhere, I'll be kicking myself when the boards tend out to be bad.

Just curious, what's in your V A drawer? You intended to open it but stopped short? Drinks? Secrets? :smiley:
