Part Ninja built on perfboard

Wednesday, January 30th, 2013

JanW built a Part Ninja on perfboard. He used a DIP cased microcontroller and through hole parts. He also replaced the 2.5V voltage reference with the similarly specced  LM385-2.5. The connections were made with enamelled copper wire AWG 28. The lacquer is burned off by tinning it with a very...
