(But I’m not really tweeting much these days)
4 months ago, I read about Johan’s Nanino on Hack-A-Day, and thought it would be a great way to teach some folks how to etch their own circuit boards. Although I’m increasingly shipping PCBs off to China, being able to etch your own boards is a valuable skill to have. I’ve taught workshops on it in the past, and I’ve described the process on this blog. Today, I set out to make a copy of Johan’s Nanino, but was almost immediately frustrated by the inability to manipulate and print the board file in a way that worked well for my process. In the end, I redrew the thing using DipTrace.
The only change made to the original is the addition of a .1 uF capacitor on the DTR line of the FTDI header. Some of the traces are a little closer together, but they’re still spaced out enough that etching this board is a cinch.
Here are the files:
You can use this PDF to etch directly. No mirroring is needed.
