OK, I finished off the last few fiddly bits of the build, so now I can officially say that "It's Done" and more importantly "It Works!"
Full N00B disclosure of the areas I struggled with, include:
-Soldering ANYTHING with a larger ground connection (example voltage regulators) made a solder blob mess, until I adjusted my iron heat setting to ~750 F.
- After much troubleshooting, I realized I had to redo all of the board to board mezzanine connectors between the control surface and base PCBs. I hadn’t made them long enough to to establish good contact.
But, honestly everything else was really straight forward and it’s been a very rewarding experience to work on and play with the results.
I can’t say enough about the collective efforts hat went into the design, documentation, PIC programming, etc. a real community effort (wow).
As I’ve said elsewhere, I’m already working on a big brother MB-6582 project, so I can have multiple instruments playing at once. I know my experience with the sammichSID will come in handy...
...I am left wrestling with an ethical question though...
If I did actually buy a set of Chinese knockoff PCBs, is anyone getting cut out of their commission on them (i.e., Wilba, TK, nILS, etc.)? ...or are the volumes they're selling on eBay likely to be so low that it’s not really a big concern?
Thanks again everyone...
Cheers!
