"keep an eye on randal and his synth cases... he just announced a 40$, stackable solution for frac and euro.
add $60 for PSU. $100 and you're ready for modules! there's a contest too...

further on the horizon, cal-arts and buchla style cases, and a line of ATA carry-ons.

Richard Brewster Ian Fritz Teezer Through Zero VCO

via Richard Brewster's Synthesizer where you'll find more info and samples.

snip...
"This module is a sawtooth-based VCO capable of frequency modulation (FM) extending past zero frequency into the negative-frequency regime. Thru-zero FM provides a much wider and richer variety of sounds than “ordinary” (positive frequency only) FM."

TinyRhythm DIY Drumsynthesizer Overview

YouTube via stereoping
"My TinyRhythm is finished. A little tweaking on it. It is a 8 channel Drumsynthesizer triggered by Midi. It can learn the midichannel it listenes to. Has some individual outputs and two triggeroutputs. The mixer-faders have an led which flashes when the channel is triggered. Each channel is based on a Atmel microcontroller and has as few as possible additional electronic parts. Just a proof of concept for personal learning on µControllers.
The simple "one-Transisor"-VCA concept" in some modules and the very simple mixer with accent-input is shamelessly copied from the dr110. For the Accent I added a 'time' parameter which makes the decay of the levelemphasizing much longer."

TinyRhythm DIY Drumsynthesizer Top 4 Instruments

"Some tweaking focused on the first 4 Drumchannels: 1. Bassdrum based on a lookuptable-envelope and a trianglewave, both sent out by PulsWidthModulation with analog VCA behind. 2. full digital Sid-Style-Snaredrum - very simple, just a tiny13 and a dual opAmp. 3. Hihat is alos very digital - besides shofted noise it can also make some spectra generated by 3 digital oscillators. And 4. TomTom, which sounds more than another Bassdrum. Depending on triggerstrength it can make 3 different pitches."

TinyRhythm DIY Drumsynthesizer Bottom 4 Instruments

YouTube via stereoping
"Some tweaking focused on the other 4 of 8 Drumchannels: 5. Clap which can also make some Guirosounds, Its kind of burst generator triggering 2 analog Envelopes, sound source is digital noise or some multioscillator-spectra running through an analog VCA (quite a copy of the dr110-clap but with with digital brain). 6. is Cymbal which can also make some cowbell-sounds. The sound runs through a bandpass which is frequencymodulated by an LDR + an LED. The mode-dial can set sample/hold, LFO with different speeds, envelope up/down with differen speeds and fixed 5V. 7. is the simple but cute analog Maracas/Clave from Vermona ER-9 and last one can make 3 different sounds, based on triggerstrength: Clave (from CR5000) which sounds more like a nice 'bek' than a clave, another Clave (from TR808) with MUCH more parts and at last an "accidently-coming-out-as-another-Noise- Snaredrum"-Rim-Module from 808."
