So, I had a surprise delivery this morning… 10 PCBs for the new synthesizer.
These are just two-layer affairs… with the idea being that anyone can manufacture these themselves. The top layer if made at home is done just by covering one side of a double-sided PCB with tape. The other can be done by hand with a dalo pen, using photographic methods or using toner transfer.
One thing I did have originally, and lost when I told Kicad to delete all footprints when re-working the design, is the mounting holes in the corners, something I’ll have to re-add.
I’ll have to pick up some 74HC574s (or perhaps ‘573s, since that’s what the hobby shops sell… won’t matter for this project, either will do) and get soldering this weekend.
