Any interest in a guide to the CODA build? Finishing mine up and it turns out that programming the chip is the easiest part once you get a grip on how to do it.
Yes please
Yes please :)

Yes pls!
I, too, am curious and interested
Absolutely! Thanks
Yup

Yip !!!
Is there an existing ready-to-go PCB from Coda for this? I did a quick search but didn't see anything.
Obviously, I could make one, but I'd rather test the functionality first.
I'd think Haberdasher would etch some. Was thinking about hitting him up for some as well.
How much are the parts. Has anybody made a mouser cart by chance?
I'll go dig up my parts list and post it tomorrow. The relay, pfet, and PIC were all pretty cheap. I've retrofitted a few pedals and it works very nicely. I'm still a fan of the 1776 finish-line board for size. This won't won't do a 1590A.
We really need to change the title on this thread.
Anyway according to my records my Mouser order was:
80-EC2-5NU NEC-Tokin KEMET relay - $1.29
512-LM78L05ACZX voltage regulator - $0.257
757-TLP222AF MOSFET Photorelay - $0.855
579-PIC12F675-I/P - $1.22
Add a few resistors and caps and that's it.

No transistor in this one?
PFET (I've never heard of it either) does all the voodoo. I haven't used the momentary function but it would be fun on noisemaker type stuff.
What are peoples' thoughts on latching vs non-latching relays? From what I can see on the Coda example code, and the EC2-5NU relay used, it's non-latching. That means constantly powering the relay to keep it switched doesn't it?
Is that necessarily a good or bad thing?
Reason I ask is I'm about to do a custom board with relay switching, but I was planning to do a non-latching variety.
I'm going to use an attiny85 for the control chip, mainly because I've done lots of Arduino before and I already know how to hook that up to do the programming.
