Quote:If you want them assembled... Well they'll still be pretty cheap. If you want them in a pretty box, with connectors and plug & play you'll have to wait a bit longer & pay a bit more. I still haven't found an easy way to hack the adapter.
TravisR this site has a lot that may help. I got my pretty box here.

I bought all my stuff here and at digi-key.
Hope this helps. I trying to build the first edition PCB and dwell device.

I was going for a custom CNC simple box to fit it, and epoxy to seal the board from water. I am supposed to be recieving the first built board to test sometime within the next couple of days. I know the company that printed them turned them into a dual sided PCB for better soldering. They also mentioned other tweaks but they were too many to remember.
I'll snap some pictures when I get it.

Sorry to bump this thread but I'm doing this as my last resort, does anyone have the final Schematic and parts list that was posted here which made it adjustable? The pcb layout is still there since they were attachments but the inline images have gone missing. Can someone please post it if they have? For a 1.6 in my case. Thanks!

Unless I'm going crazy* it looks to me as if the original schematic is drawn wrong. The + and - inputs of the op-amps should be the other way around to make each stage inverting. There's no negative feedback. It'll just latch up.
*Always an option.
<edit> No, I take it back. Crazy it is. It looks like the resistor values have been chosen so it can work like a comparator (not a low-gain inverting amp like I assumed). Carry on. Never mind me.
