Here’s the coolest Arduino clone we’ve come across. It’s a Metaboard clone, which is an Arduino compatible board that does away with the FT232 USB to UART IC, and instead uses the software bit-bang USB bootloader USBaspLoader.
The design was laid out onto a single layer in Eagle. It was printed out on a sheet of paper, and wires were bent into shape based on the paper template.
Transparent epoxy??
That is so cool! I also hope they epoxy it. Looks like 2 layers to me…I bet you could do many more layers without much additional difficulty (although this looks really hard to begin with).
