finally!

Managed to etch this double sided PCB without it going wrong. There was one track that touched another, but it was a tiny blob of ink on my transparency... managed to scrape the photoresist with the end of the pointed tweezers and etch it away. so looks like we're all good to o for the next step of this prototype... well actually its more of a beta ;)

if you're interested, the little devices with lots of pins are the processors and are 10mm square (or near enough).
