DIY etched boards are the quickest way to get a project up and running. This is just what Noy did with his IR Toy, and CPLD breakout boards. He modified our projects to a single layer design. Used the toner-transfer method to copy the traces, and etched the boards with a mix of hydrochloride acid and hydrogen-peroxide.
I’m a student from Germany and I love this Blog. So a few weeks ago i tried my first etching example. So i needed a small circuit in single sided design. Because I wanted to etch a sensemaking curcuit not only an etching test, I decided to etch your IR-Toy and your CPLD Board. So I routed it to single sided and I did it with the direct toner transfer method. Everything worked great I was etching it with HCL+H2O2 (really fast!! but quite dangerous!!).
You can get IR Toy v2 for $22.05, including world wide shipping.
