?* Sony wm-F3050

video upload by Gijs Gieskes


?* is almost the same as the Zachtekind & ?Kind.
A walkman with extension circuit that is powered by the walkman itself, controlling the Walkmans playback speed with buttons linked to the potmeters next to them. It is a simple device that makes it possible to playback tape in very slow speed and switch between selected speeds, intuitive and playful.
it is stereo. Has a build in radio (AM/FM, no extra controls over this radio are added).

- input cv in for playback speed control -5v to +10v (example: 0v = low pitch, 5v is high pitch, so it is in reverse from normal).
- amount of CV can be adjusted with a potmeter.
- output audio out from walkman.

- 5x pot for playback speed per push button momentary switch.
- 1x ON/OFF toggle switch for 1st playback speed pot switch override.

- 2x AA battery, The range of the speed control pots is different when powered from a battery.

New Gieskes Klok Eurorack Module

video upload by Gijs Gieskes

via Gieskes

"This is a eurorack clock module with features related to a clock. On the left you have the audio output that is the sound that the clock makes, it is amplified via a piezo, the piezo is gated via a vactrol witha build in envelope. The clock can be advanced interlay via the build in LFO, but it can also be advanced via a external gate signal. There is a volume pot for the volume of the clock.

The center input goes via the volume potmeter above it to the vactrol, here you can put in external signals, these will be mixed in with the sound of the clock and gated with the vactrol.

Then there are two outputs for the LFO, they are one square wave and one sort of triangle wave. The potmeter above them sets the speed, when turned all the way to the left the LFO will stop oscillating and hold its state.

+12v (Power consumption should be not much, maybe 100ma)
-12v (maybe 20ma?)
Width is 12HP"

Vu Perc Relay

video upload by ggijs

VU Perc Relay

Percussion with a VU meter and a relay for eurorack

via the user manual


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.

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.

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.

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

video upload by ggijs

4 Step Swing Sequencer with many features

3 different versions available.

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.

"During corona allot happend in the world, one of the things of importance is finance. My knowledge of finance is very limited, but I was interested and started looking at videos on YouTube, I stubbled that I find interesting. I watched allot of his video’s (and other’s), this turned into the instrument called Insolventunclesam.

The landscape line represents the comes in for the rescue. Drunk Insolvent Uncle Sam is holding a bottle with dollars and is dressed as , it’s rib cage is a where you can plugin different insolvent oscillators that represent . The FED chairmans are kept in a box called 40106RESERVE. The starving oscillator is controlled by one knob but also by the 3 other oscillators that represent household investors. When they invest there arrow glows, the arrow is the shape of a house and are also pointing up because they push the frequency up. Around Insolventunclesam there are buttons labelled ELECT where the decisions can be influenced.

The is a HELICOPTER delivering in dollars and euros, when they fall down they can turn into bitcoins. The HELICOPTER gives bursts and can dominate all by pushing all signals up.

Lo-fi Mellotron Style Sampler with a Gieskes DIY hacked Walkman ( Zachteman )

Sound Provider

"A friend lent me a Zachteman for a few days and I took the opportunity to record a lot of stuff with it. The Zechteman is a kind of DIY Mellotron made from a hacked portable cassette player created by the genius Gieskes.It has a keyboard, a vibrato and even a Cv input that controls the pitch and a Gate input that controls the vibrato (Perfect to use it with my Eurorack Synth).
For this demo, I used my Aiwa Cassette Recorder to record a single note with my Analog Synthesiter Moog Werkstatt for 5 minutes and then I used the cassette with the Zachteman to create a melody.
For the last part I added some effects with the Zoia of Empress Effects and I took the opportunity to make a quick Beat with sounds I released on Sound Provider( Analog Now & Techno Now / ) with Maschine Plus of Native Instruments, it allowed me to see that the sample banks of sound provider also works well with the Hiphop 😊😉

Modular Synth Music // Gotharman's anAmoNo X #TTNM


"Gotharman's anAmoNo X is a modular synthesizer workstation with analog filters, digital oscillators, audio samplers and granular effects in a small convenient box. Of course the first thing to do with a modular synth is to patch up some bleeps, bloops, analog filter pings and ambient noises. It's just so much fun and especially lovely in stereo! No samples were used, only the internal synth engines, and no external effects, apart from a little EQing and compression during video editing. As a visual treat you get some of Gieskes' 3TrinsRGB+1c analog video synthesis."
