From the album: MIDIbox ASIDITY
The front panel is finally working! It's not entirely done--we have to get the LED displays and LCDs working, but the matrix works! -

I had wanted to wait to show the case until it was all done, but after a day in the metal shop (back panel and top section of front panel), this photo was too good to pass up. :) -
From the album: MIDIbox ASIDITY
We finally finished soldering the SIDFB module boards! Each board contains two SIDs and their shift registers; a CD4052-based digitally-controlled filter capacitor switching circuit, 4 pairs capacitors per SID; LM1973-based digitally-controlled audio attenuators controlling feedback to self, feedback to other SID on the board, feedback to SID on next board, external audio output, and master L and R outputs; and the mixer circuit for all the feedback inputs (and external input) to each SID. The boards are custom-manufactured. The total across all four boards: eighty ICs, 248 resistors, 224 capacitors, 24 transistors, and sixty connectors, for a total of 2600 soldered holes! -
From the album: MIDIbox ASIDITY
This is one of the four SIDFB module boards that will be in MIDIbox ASIDITY. It contains two SIDs and their shift registers; a CD4052-based digitally-controlled filter capacitor switching circuit, 4 pairs capacitors per SID; LM1973-based digitally-controlled audio attenuators controlling feedback to self, feedback to other SID on the board, feedback to SID on next board, external audio output, and master L and R outputs; and the mixer circuit for all the feedback inputs (and external input) to each SID. The boards are custom-manufactured. The board contains twenty ICs, sixty-two resistors, fifty-six capacitors, six transistors, and fifteen connectors, for a total of 650 holes.
