[RichDecibels] wrote in to share a new device he built called the “Sinster Tone Generator”. It’s basically a bass drone synthesizer that uses two pairs of heterodyning oscillators to generate the output. If you swing by his site, he has a long audio demo of the device in action with a bit of reverb and filtering applied to enhance the sound. After listening, we agree that it sounds pretty sinister!
The device is relatively small and handsomely packaged in a plastic project box he had custom cut by Ponoko. [Rich] says that this particular unit is a one-off that he has produced for a charity auction, and that bidding is open through Sunday if you really want to get your hands on it. If you happen to have the time to build one yourself, he has uploaded schematics and layout files to his site (as usual), so feel free to stop by and grab a copy.
Sounds like my farting keychain when the batteries run down.
I freakkin LOVE this! Nice one!
I’m actually more interested on that neat looking casing. I wonder how difficult making similar construction with hand tools (no laser cutter here :/)
his site exceeded its bandwidth already :( I’m too late to the party
found a working audio version here

Ah peas! Sorry about the bandwidth peeps that’ll teach me for living in the third world. My ISP tells me they’ll have it reactivated in “12-72 hours”.

Wow. I like the heterodyning trick with shared capacitor. I’ll try it on my Lunetta(-like) synth soon.
BTW casing is also very nice.
