Atari Punk Console Kit - Eurorack LoFi Oscillator DIY Kit

After a half hour soldering all the parts in, I plugged it in and turned the knobs and was instantly rewarded with the insanely metallic yet musical chaos that is the Atari Punk Console. I then plugged in two different speed LFOs to the CV inputs and when it scans through the sonic islands, it's like you've slowed down time. Note that not all knob positions create noise, this is normal for an APC. Also, it's only when you turn the knobs that you get the great sync and pitch dynamics, otherwise it's just a fixed pitch pulse wave oscillator, or off which is even more boring. If you're not familiar with APC, it's two 555 timer circuits generating square waves where one sets the base pitch, and the other steals different chucks of time away from the first, creating non-linear pitch and harmonic cycles as you turn the knobs. I wouldn't start with this kit if you've never soldered before, but if you know how to solder and have put a few other step by step kits together, this one is quite easy to figure out. You will want to have a multi-meter to double check the resistor values, and you need to know that the mini-coke-can capacitors and diodes have one direction that is the correct, and the other which will prevent the circuit from working. If you know that, the rest is easy. One last important detail, the CV and the knobs add together, which is a very good thing, but if you're using an LFO to drive this you'll probably want some way to limit the range of the LFO cycle. I can't wait to get a hold of a sine-wave or complex smooth LFO, triangle ones creates nice cycle runs but it's very obvious sonically when it changes direction. Lots of fun!
