Best PCB so far

This is the printed circuit board for the ultrasonic down-converter I wrote about in January. Silk screen made with toner transfer came out particularly nice on this board.

I left the circuit board (with the paper stuck to it after ironing) in water over night. After peeling off the paper and drying the board there were still some white paper fibers visible. I found out that they can be easily removed with a soft pencil eraser. The result isn't perfect though and I still would trust this technique for etching, but it is more than good enough for the silk screen.
