Far beyond simply open-sourcing the schematic, Eric Archer posted a full step-by-step for recreating his Mini Space Rockers drum-synth kit on protoboard. Hmm â€¦ I get the feeling he really wants us to build these =] – very awesome.
Included with the project is a list of 25 variations for achieving a wide range of different sounds, all the way from “Thump Bass” to “Space Hawk” –
First choose which sound youâ€™re going to build. [â€¦] Thats how you determine what values to use for capacitors C1, C2, and C3. What they do: C1 and C2 set the pitch range and affect the pitch envelope. C3 determines the decay time of the sound. Iâ€™ve tried up to 100uF here, which gives some looooong sweeps.
So build a wee space rocker, won’t you? – and be sure to post some audio of the results.
YouTuber datenkrieger75 built quite an excellent technobox featuring a patchable circular sequencer, a Gakken SX-150, and Mini Space Rocker circuits. Things start to sound prett wild (and eerily voice-like) around the 1m30s mark.[via Create Digital Music]
