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.
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.
Horray!! Finished my DIY electro-acoustic-feedback-string-drone instrument Ancellique today. Most of the work was done at the Sommercamp Workstation in the Haus der Kulturen der Welt in a workshop supervised by Halldor Ulfarsson.
The strings are recorded through four self-wound coils. The signals of the strings can be separately controlled by four potentiometers attached to the side of the body. The speaker at the back of the instrument is connected through a 40W power amplifier - also inside the body - with the mixer of the coil/string signals.
So basically all the sound that is recorded on top of the body is played back immediately through the speaker at the back of the body, creating a nice electro-acoustic feedback. Mostly you don't even need to "play" the instrument, it's enough to just turn up and down the pots of the string volumes.
The body is from an old broken guitar, the tailpiece from an old electric violin, the bridge selfmade, nut selfmade, tuners are piano tuners, the fretboard is made out of on of those sanitary tubes and all the way through the instrument there's this curtain pole running for stability.
Here's my SSL Clone, the Zauner Ultratight. Schemos can be found at Gyraf's webpage. Mine has the Turbo Board installed which makes it switchable between stereosum and dual-mono ("true stereo") compression.
Finished my diy 4-way mixer today. Active mixing of four channels with gain and a small level control LED and some nice big knobs from an old broken echo/delay machine. The name is a side blow to all the shitty Behringer products starting with "Ultra...".

Finished my power supply today. It provides stabilized symmetrical voltages at +/-12V and +/- 15V. Artwork by Borelia Borschtsch, a Zauner-Borschtsch Kopro.
