Pimp his Guitar

Small modification of an active acoustic guitar of a friend of mine: I made the built-in preamp switchable with a nice big toggle switch in Les Paul style. In addition to that I built in one of those small blue blinkies we geeks like so much. Looks nice!

Pseudo Crackle Box "Mimi"

Another nice present for a friend of mine. It's a pseudo crackle box made up with just three components: 2 capacitors and the LM386. Each leg of the LM386 is connected to one of the electrodes.

The housing is - which can easily be seen - made of a reciever of an old telephone. I guess everyone had one of those in their hands for at least one time in their life. Playing it gives you somehow the same feeling like writing a SMS on your mobile phone so it feels quite familiar to touch and use this neat instrument although the audible outcome of your operation might be most unfamiliar.

This piece will be exhibited as part of the exhibition "Technological Singularity" from March 25 to April 23 at PlanetArt, Amsterdam. Come and try it!

Some sounds and noises played with Mimi by Phillip Tesner.

Pressure Controller "Hubert"

This is a small but powerful device to use with your modular synthesizer. On each hand side there is one force sensing resistor turning applied pressure into a steady CV output.

Each channel has three outputs: CV Out, Inverted CV Out and Gate out. Each side is capable of holding the current voltage on CV Out, whereas the inverted CV appears on Inverted CV Out. If a CV is held in the CV Out you still can use the inverted out, even switching from positive to negative voltage as often as you want without disturbing the held CV output.

In addition each of the two channels fires a gate signal every time pressure is applied to the pressure pad. The CV can go from 0V to +/- 8V and can be controlled in sensitivity.

The device seen below is the prototype. The actual layout of the finished controller will be slightly different and of course much more neat. 100% analog power.

Right channel controlling the cutoff frequency of a Doepfer Lowpass Gate, left channel plugged into Wavetable CV input of the WMD Geiger Counter.

Yesterday night I was helping my friend to make a nice Christmas present for her boyfriend. It's a kind of six channel opto-theremin controlled by six LDRs with your hands and fingers. run off a 9V battery. Design by Borelia Borschtsch, a Zauner-Borschtsch Kopro. Fotos by Georg Oberlechner.

Just finished the Christmas present for my flat mate. The tripple-eyed, double-tailed, coin-expelling and in every other way not less interesting noise-musica(n)t Pia.

Chaos circuit with 4 electrodes, 2 antennas and 1 LDR.

Some sounds and noise played with Pia.

Light Amp

Built a small amp into an old broken desktop lamp run off by a 9V battery. Output is 0,5W with a switchable gain factor between 20/200. Ideal for testing coil instruments with low output level but also very suitable as a small guitar amp. 0,5W is more than you think!

Some free guitar improvisation played on the Light Amp with different gain settings.
