Logic Noise Klangorium DIY Glitch Synth by Elliot Williams


via this auction
"On offer here is a PCB to build your own DIY synth based around CMOS chips, it is based on a series on the Hackaday website by Elliot Williams, I made a few of these and had a few boards left over, last couple remaining.

It can be used to make all manner of things, examples include drum machines, drone synths, sequencers and so on, or it can just be built as a playground as intended for further prototyping, it is up to the builder. It can be built as a complete project, or just the sections you require, it can be built into a suitable case as a standalone instrument for example a drone synth, with the controls on flying wires rather than soldered directly to the PCB etc.

It goes without saying that you will need to have a fair amount of experience and the tools and parts required to build this, I would not recommend it to complete beginners. No documentation other than what is in this listing is provided, so if this is not enough then this pcb is not for you.

Parts to complete the build are not supplied, you need to source them yourself and budget for the cost of those, I think it ended up costing me about £15 in parts to build, but it depends on what components you buy and where you buy them from.

NOTE: This is purely a DIY project and I offer no technical support, search for the project page at the hackaday website (klangorium logic noise) - ebay forbids me to post the link unfortunately for some bizarre reason, which is why I had to end the previous listing with the web link.


Klangorium Parts list

Note: This list is what I used, I believe it to be correct, but use at own discretion.
Please note there may be errors, omissions, wrong quantities or incorrect values, although I did try to ensure it is correct the responsibility is your own, and certain parts can be down to user preferences anyway.

Semiconductors
20 1N914 or 1N4148
1 2n3904
2 5mm LED red/green/orange as preferred

ICs
2 cd40106
1 cd4015
1 cd4051
1 cd4040
1 cd4017
1 cd4070
1 cd4069ub

IC sockets optional as appropriate (recommended)
14 way x 4
16 way x 4

Capacitors ceramic all 2.5mm pitch
100n x 18
10n x 7 (6 used in "Six Oscs")

Capacitors electrolytic 2.5mm pitch
10uf x 3
100uf x 2
1uf x 1


Resistors all 1/4 or 1/8w
2 x 10k
3 x 1k
20 x 100k*
5 mixed values for "Six Oscs" I used 100k*, 220k, 330k, 390k, 410k, 560k

10 Alpha 9mm snap in potentiometer 100k
1 Alpha 16mm dual potentiometer 100k + knob as required

Resistor networks 9 pin 8 way common array
1x 100k and 1x 10k if you want different gain on left/right
Or
2x 100k if you want left and right to have same gain


2.54mm pitch female pin headers
2 way x 20
3 way x 18
4 way x 12
5 way x 1
6 way x 2
8 way x 4
10 way x 2
12 way x 2

1 x 3.5mm stereo socket

9v PP3 battery wired connector

2 x tactile switches 6mm

Mixed pack of male to male breadboard jumper cables, flexible type.

I also recommend to mount the board on a piece of perspex or similar along with a solder-less breadboard, there are 6x M3 sized holes, so 6x M3 bolts, nuts and standoffs would be needed.

Use standard leaded solder for best results."
