Currently on Kickstarter where you'll find additional details and some videos.
"The goal is to develop a catalog of experimental instruments in order to evolve the electronic music production scene. The project will deliver new ways to interact between digital, analog and the physical environment."
The campaign starts with four proposed devices: an analog mono synth, analog drum synth including eurorack modules, and envelop module, and a analog controller that is already developed. There are a few other prototype pics further below.
Some details on each starting with the Thundervolt MK1 analog mono synth:
"The second prototype, a monotone lead synth, is called 'Thundervolt MKI'. It features two oscillators, an Attack-Decay-Release envelope, a special one pole filter and several stages of distortion. The synthesizer is able to create sounds ranging from industrial and percussive sounds to harmonic bells, interplanetary pads and distorted basses - and numerous further electronic moods."
