"VU-PERC-RELAY MANUAL (MAY 2022)

_ABOUT:
The vu-perc-relay is a drum sound module for eurorack that uses a vu meter to hit something (in this case a copper strip and a LED leg) that is connected to a piezo element.
And a relay is triggered and amplified via another piezo element.

_IMPORTANT:
Stripped tubing from a electrical wire is put over the tip of the vu meters hitter, this prevents the vu meter from making direct contact with the spring.
If the hitter makes direct contact with the spinge there will be a large click, because its sort of short circuiting a bit.
So make sure the hitter is hitting the spring in the correct position.

_VU METER CENTERING:
There is a trimmer potmeter that you can use to set the center position for the vu meter,
the vu meter moves left and right to hit the different metal parts.

_CROSS FADE TRIMMER
There is a small trimmer on the board that holds the relay and the vu meter, this can be used to croos fade between the vu meter and the relay,
it does not really cross fade the volume that much, it will just make one less dominant in how sharp it sounds.

Gieskes 4Swing

4 Step Swing Sequencer with many features

3 different versions available.

https://gieskes.nl/eurorack/?file=4swing

via the user manual

"A module that has multiple functions, VCO/VCLFO (1v octave), sequencer, clock divider, swing..

The 4Swing refers to "for swing" and it has 4 steps. The module can do quite a bit of different things. It can be a clock divider, VCO, VCLFO, sequencer with swing or without.

I developed it because it wanted a DIY version of the Doepfer A-147, a module I use allot. But then in combination with a simple sequencer/clock divider, basically a setup i use almost always but then in one module, a bit like this module i used to use allot. The Motor Bin module uses a binary clock divider, but the 4Swing uses a 4017 (decade counter/step sequencer), so it's a bit different. The reason for this is that i wanted swing (i used to use Groove allot in LSDj, i think it would be great to have more swing in my eurorack) and you cannot have swing with a binary clock divider.. i think.

Gieskes Starving binary + Vu-Perc

video by ggijs

0:00​​ Starving binary trigger's vu perc's, in the second part the square wave output form the Doepfer LFO goes into the cv input of the Starving binary.

1:00​​ A more complicated patch where I control the whole sequence with the offset of the CV input of the Starving binary. The CV input of the Starving binary is connected to one of its own outputs.

Gieskes VCOFan

0:00​ VCOFan audio out to VCOFan volume CV input, and then Doepfer LFO to VCOFan volume CV input of the first VCOFan.
0:00​ VCOFan audio out to VCOFan volume CV input,
1:28​ Doepfer LFO to Starving Binary clock in, Starving Binary outputs to VCOFan volume and pitch CV inputs.
2:28​ Phone light to VCOFan module (it clips of the excess volume created by the phone light)

I was watching the news on TV and they were talking about Coronaparty, showing kids hiding in the forest between the trees, some had tie wraps around there wrists, it spoke to my imagination.

Triangle/Sine waves the natural sounds on the ground and the digitaly created signals in the tree tops. (Controlles on the tree trunks)."

Sounds like a bird chirping with spring reverb. Curious if the marble does anything or if it's just going for a ride.

Reverse DC Motor (eurorack module)

Published on May 3, 2019 ggijs

via geiskes

"CV OUT: Rotating right gives positive voltage on the CV output, and rotating left will give a negative voltage, no rotation will give 0 volt.
The faster you rotate the higher the voltage will be.

AUDIO OUT:
The faster you rotate the higher the pitch and the higher the volume will be. But the volume is clipped by diodes to never go over around 5v peak to peak.

POTMETER:
Adjust the range of the output signal. on the audio out it will also set the amount of clipping by the diodes (distortion)."

More oddness from synth gear maker gieskes.
In short, the little paper blocks a laser shining on an LDR (light dependent resistor), which in turn causes the reset pin on the Gameboy to activate. I just like looking at it.

I'd include the specs here but apparently gieskes uses gifs for each letter on his descriptions. Really.
