13. Radiolight


An old traffic lights kit modded to a 3 output sequencer. 4017 is doing the sequencing in this one, original circuit was two traffic lights (green, yellow and red) slightly modded to get more interesting output.

12. Nurse beats


A drum synth and sequencer using 4000 series logic. 4069 as filter, distortion, mixer, 4046 vco, 40106 doing six oscs modulated with four XOR gates in 4070 for noise. Four 4052 sequencers for 4 drum sounds, each can be slowed down individually.Triggerin
can be 1/step or multiple also outputs triggers (snare,bd) for syncing external stuff. Atari style joysticks can be used as controllers for live playing

11. Ammobox of APC

Ammobox project is one of those projects that allways keep coming back. It was started by me round 10 years ago. I was supposed to build a small modular synthesizer, but only got one astable multivibrator module made. IMG080.jpg Case was a bit overkill for single unit, thought it did look good live, like in this photo at Taidehalli La-bas 2003. taidehalli-labas723.jpg After that ammobox was forgotten to the shelf for couple of years, untill Daniel found it round 2007. He ditched the multivibrators and build Atari Punk Concoles. After that ammobox had 4017 controlling relays giving power to four Atari punk consoles with selectable capacitors. In this form it was used on numerous concerts, installations and recording sessions. At some point it did eventually break, and it was forgotton to the shelv again for couple of years. 2011-11-23-_MG_9550.jpg In 2011 Harri found it, repaired it, and desided to add external clock input, so now it is ready to be used in 101 sequencers project.
