I second this! There are a lot of great PCB layouts buried in this forum. I know I've spent a lot of time trying to find PCB layouts that I KNOW I've seen on this forum somewhere. If there could be a sticky at the top with links to PCB layouts in the forum and elsewhere I could save a lot of time and questions.

[blue hell]

Please go ahead and collect/index the layouts, I'm sure someone will make this topic into a sticky then

This is a great idea. The perfect thread for: well you know I've got at least a dozen or so projects going right now, so I should probably start a few more! Seriously though, excellent idea.

I would be thrilled if you could add a couple of my PCB/kit offerings!

Sequencers:

sympleSEQ -- http://cv.hexinverter.net/?projects=sympleseq-v10

seqSQUARED -- http://cv.hexinverter.net/?projects=seqsquared (technically it is a sequencer expander/programmable switch that turns small sequencers into much larger ones)

Few schematics over at my blog too , well ..it's a blog about schematics
