lots of mechanical noises. The vast majority were mechanical calculators.

Summer of Synth-DIY – week 12

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…)

A combination of Tip Of the Pops wheelbarrow sound system, and my crazy homebrew synthesizer:

I also contact mic’d my 4-track for no good reason. Sounded awesome, though:

Summer of Synth-DIY: Week 11

Lots of progress on the Cigarbox- added a three input diode mixer, a four input additive mixer (i.e. passive resistors), a proper 1/4″ output (so no more needing to hook alligator clips up to the amp), exposed Vcc and Ground points, and a CD4077 quad XNOR module for pseudo ring modulator fun!

I’ll have to add some more modules and features soon – probably some CD40106 oscillators, maybe a starve pot for Vcc, and who knows what else?

I’ll add pictures (and who knows, maybe a video?) soon. For now, imagine it looks like it did last week, but with a lot more screws sticking out of it ;-)
