Hi there. I'm John. I have a 300in1 electronic project lab in my lab, and I am slowly making my way through the projects as part of my electronics hobby. The various projects are listed in the sample manual and duplicated in the projects section below. There are some admin notes for John's use.

Notes

Long leg (anode) positive.

Short leg (cathode) negative. (Line/band near cathode).

Emitter - Collector - Base
