What inspired you to do this?
Once i've learned to built oscilators based on the integrated circuit CMOS 40106, and knowing that you can build up to six oscilators with the same chip, i knew i have to develop a multi-oscilators sound machine. Next thing was the low pass filter addition and the instrument was closed.
How long did it take to make it?
We take 2 weeks to build one from scratch.
How long have you been doing things like this?
We have been building noise machines fron 7 years now, but they weren't this smooth looking and sounding at the begining. We keep improving our products year after year.
How much did this cost to do?
About 80 dolars.
Have you done other things like this?
Yes, we do have another items we designed based on the same architecture.
Are there plans available to make this? Do you sell this?
We do sell this kind of instruments. We don't have much documentation about it but we do give workshops to teach interested people to know how to make it and other electronic instruments like it.
Nicholas Collins "Handmade electronic music" book, Hackaday.com blog's "Logic Noise" series, "Synth DIY for non engineers" facebook group, Modwiggler forum and many nice people who share they knowledge over the web.
