MiniSpotA spot welder

[rojitor]

Going back to the discussion of sandwich spot welding, I have tested this method to weld copper with the MiniA

The scraps at the left are the aftermath of the sandwich method. At the right is a direct spt weld on copper.
Direct is far superior with this machine. No need for the sandwich. 4-5ms on 3s is enough for 0.05 copper.

It's amazing, and even more so that he left the plans up / AFAIK it's open sources hardware ! I had lots of fun trying to make mine. I just need foil and a bigger battery to test it with [emoji14]

I decided to make myself a challenge and shrink it down to 1cmx10cm with smd so I can machine a pen shaped heatsink... If I did it'll right I'll try to keep shrinking it (for science of course).
