Description

Discussion of electronics for beginners and experienced alike. Hopefully we can all exchange ideas, circuits, schematics, and pictures of all disciplines of electronics including both analog and digital.

When asking for help, be specific, please. But don't forget to give us the big picture. Often it's easier to help solve your problem, than help solve your solution.

Also visit the Homebrew_PCBs list for information on making printed circuit boards: Homebrew_PCBs

Please note, this is -not- a job posting board.
