Making PCBs

Posted on April 19, 2016

So, I’m ready to progress with my AudioFreeze project, and move from breadboard prototype to permanent module. I didn’t relish the thought of transferring the circuit to Vero board, it would be possible but fiddly. I toyed with the idea of fabricating my own (see, but a friend made me aware that you can get very low (10 or so board) runs of unique PCB designs factory manufactured for around £25, so roughly £2.50 a board.

I downloaded Eagle Light Edition, PCB CAD software. It’s free for non-commercial hobbyists to use (with a maximum board size 100mm x 80mm, which is fine for my needs). To say it has a steep learning curve is an understatement, its UI is rather non-standard, thankfully I had someone very patient to mentor me and get me started (thanks Jason!)

It took me a couple of iterations, but the board design is now finished, let’s hope it works! Just a 3 week agonising wait for them to be delivered from Hong Kong!
