Almost added a passive LPF to the cigarbox, but then I decided I think I’m going to try to keep it purely “digital” (i.e. all CMOS squarewave-y stuff). I also played the cigarbox on the air Wednesday, and showed it off at Playshop on Saturday. I also started to clean up the power management inside the box (no more internal alligator clips! an on/off switch on the outside of the box!)
I also started on a companion box to the cigarbox synth – my own take on the Beavis Audio Armageddon Processor. Also in a cigarbox. So far, the first module is the VCF section from the MFOS Weird Sound Generator (admittedly, not the best VCF on the planet, but the part count is small, it was this week’s Playshop project, and it fits on a Radio Shack 276-159 board.) I’ll probably be adding some of the Armageddon Processor’s modules as well (the 567 modulator for sure, and maybe the weird LM386->555 creation as well…)
