Duckin Fummy's Guide to PIC programming: CODA PCB

[gordo]

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.

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.
