Rockit 8 Bit Synth Kit

I just stumbled upon this cute little monster, the 8 Bit Rockit Synth… and, as I know how much work it is to just solder an existing kit or project, I pledge deep respect for someone who is willing to invent a new synth without having a company or sth. similar behind him. Matt Heinze just did this, and it actually sounds like fun!! There might still be some additional work to do, but I do really like the idea of starting his own company with this project just from scratch.

so check out the Rockit 8 Bit synth, there might be more to come soon…?!

More info about his project can be found here:

DIY Project: the NXT-606 LEGO Drummachine

Just found this on de:bug: a fun little DIY project from Peter Cocteau, built with LEGO, the great colored plastic toy for children… as I loved LEGO when I was a kid (especially technic-LEGO) I really digg this great invention… maybe I will build this in the near future?!?

Have a look:

Roland Trigger out for the MB-808

As an add-on to my MB-808 I have built this small circuit to trigger the internal sequencer of a SH-101 as well as the the arpeggiator of a Juno-60. The original trigger signal of the Roland TR-808/606 and some other Roland instruments has a square waveform with a duration of 1ms, and a minimum of +2,5V, while the trigger signal from the MB-808 circuit is way shorter; With the friendly help of some people at the german synthesizerform I built this small circuit, grabbed the two trigger signals from the shift registers of the Midibox Sequencer, activated these two external triggers in the Midibox firmware and led the two trigger signals to external jacks on the back. Quite easy, and a lot of fun!
