[sdiy] What;s going on with that dsPIC ?

[Michael Bachman]

Tom asked to see a few pix of what state my DIY project(s) are in...
well, I'm still working out all the bugs on the sound card, but I
uploaded some progress to date and the project I just finished to
Flickr.

Take a look if you are curious.. I'll keep updating that set as I progress.

This PCB is a rough one as it is the "debug board".. there was alot of
talk about proto baords and vector boards etc on th email list this
week.. For me, on something this big, I like to go straight to PCB..
yes it is more difficult to change values, but I don't have to wonder
if it is the design or the proto board when I am debugging.  And when
it's done, it is easy to duplicate it to a "clean" copy and use it in
a synth (I have 6 PCBs)
