Midibox SID V2
After completing the QuadSID, I had one leftover encoder. The most obvious use for it besides spare parts? Yep, upgrade my Midibox SID incorporate the simple Control Unit A. After a bit of modeling, I decided to use a single perfboard copper tracks facing up (aka the same approach as with the QuadSID). Difference being, as there is no keyboard frame or such underneath, I can mount the electronics directly to the lower side of the board and use the LCD as mounting support. So, first step.. fashion a piece of perfboard approximately to right size, matching the display element:
Not much to it really after this. Just drop in the parts, cut the copper stripes in appropriate spots and solder in parts & bridges..
..and here are the close ups from the upper and lower sides of the plain control unit board..:
After the board was complete, I drilled holes for the buttons and encoder to the casing, removed the old stickers, lightly sanded the casing (light enough to leave some of the old scratches intact ;) and gave it a fresh layer of red and new set of stickers. The encoder knob wasn’t an exact match color-wise, but maybe I’ll come across a better one some time later.
