Critique my first PCB
carl0s:
Another weird thing is that R1 footprint.
It's a metric 1608 (should be same as an 0603) from the Cern Altium library. The footprint looked like an odd size in the end though and I've actually put an 0805 resistor on there. I've done two of the boards now and it seems to fit OK. All the caps are 0805 anyway. Sort of figured there might be less chance of tombstoning with bigger bits / more paste etc.

That has worked out remarkably well for a first PCB. In the future I would suggest using thicker traces in the switching regulator area, and keeping everything as short as possible there but it seems it has worked out ok in this case.

Thanks for the tips. Yes I'm pleased! :) I did burn up one of my LCDs mind you. Thankfully just as $25 one.
I really do need to get a current limiting PSU that doesn't take up half a desk.. I might look at those modules that Dave reviewed some time ago. Those all over eBay.

Last pic, cos I'm super chuffed :D

That looks really good, it's always very exciting when a complex display like that actually works. That would make an interesting analog style desk clock or weather station, I've always been fond of analog dials.
