I was intrigued after stumbling across the Lunetta threads at Electro-music.com . I had been searching for sequencing options for my circuits and CMOS logic chips held the answer. The simplicity/complexity of the Lunetta concept was just the thing to achieve the ordered chaos I was looking for in my music.
This project will use traditional Lunetta modules but I also wanted to use it to control other devices, such as the sound effects circuits from kids books, circuit bent toys and drum modules. I'm using pc817 optoisolators as switches to trigger other circuits with the pulses from the Lunetta.
I'm kind of new to this whole documentation thing, but I'll try to keep this updated as I go.
One dumpster salvaged rifle case measuring 12"x38"x4.5"
Recycled stainless steel bolts as lugs to attach alligator clip leads
Repurposed PVC fence post material for use as panels
Various 4000 series CMOS logic chips- inverters, multiplexers, dividers, counters, gates, shift registers and switches
Various LEDs, resistors, capacitors and other passive components (bought in bulk directly from China for rock bottom prices).
I'm super busy so bear with me. Gulf Coast MakerCon is in less than two weeks, our makerspace soft opening is a week later and I'm doing the Galileo Hacks project with Make, so my dance card is full. I've made a lot of progress on the Lunettic, but I have not drawn up the schematics or any of the documentation stuff yet. So far I have 6 LFOs, 6 inverters, 1 multiplexer, 2 dividers, 4 10-step sequencers, 2 DACs, 1 optical DAC, 6 square wave VCOs, 6 voltage controlled switches, 2 FMVCOs, 1 voltage controlled stepped tone generator, one slacker melody generator and a four channel mixer with a built in amp and speaker. I'm planning to add 2 of Eric Archers mini space rocker drum modules, a very lo-fi snare module, another four channel mixer/amp combo and a couple of filters. It all had to be stage ready by Saturday, april 5 so I'm starting to sweat. No worries- more soon.
