Pulse Modular Music Fest
I’ll be hosting a DIY workshop at the Pulse Modular Music Fest where you can build the VCF-1 from kit. Entrance for the event is 10€, the workshop is an extra 25€, which includes the kit (PCB, Front panel and all components) So if you’re in the area, don’t hesitateRead More
VCF-1 – Vactrols
I’ve been asked if I could do a workshop about synth building. While there are no solid plans to do so yet, I was thinking about what to build during such a workshop. It would be cool to have something to take home you’ve build yourself during the workshop, andRead More
Percussion – Metal-o-tron
This one is a re-build of one of my first ‘designs’, if you can call them that way. Nevertheless, It’s a percussive module designed for all kinds of metallic sounds; cymbals, hihats, gong, bells, plate hits, cowbells, trash cans, … you name it. Since I’ve build the first one I’veRead More
Spring-reverb
It was totally unintentional, but in the mess of old broken gear I stumbled upon the remains of my very first guitar amp. It was a Hohner SP55 I bought 2nd hand somewhere in the 90ties. A pretty unremarkable transistor based amp which never really tickled my pickle so toRead More
Power supply
I’m slowly working towards a project, it’s still not ready to be disclosed though, but it needed a dual rail power supply. I’ve always bought Doepfer DIY kits for my Eurorack needs, but I needed a +14V/-14V for this project. Since I could use an extra +12V/-12V supply as wellRead More
Envelop Follower – Follow Moe
This is an envelop follower. Since I build an input module I kinda wished I had one of these so I made it a little project, fun for the whole family well, not really, but anyways..)Read More
Buffered multiple
A very boring yet crucial part of any setup. A buffered multi always comes in handy and it’s pretty easy to build as well. Since I was building one myself I added a few leds to indicate signal and it’s polarity, that way I got some indication what’s going on.Read More
Input module
It shouldn’t be all weird stuff, sometimes one needs some simple building blocks. After a bit of experimenting with sending audio from the mixing desk to the modular I found myself short of a way to amplify a line level signal to the audio levels used in a modular. Hence,Read More
The Oscillator One – update 1
I’ve put some updated schematics for the oscillator one online. Changelog: Changed Linear Ramp output volume so it’s in line with the other ones (R59 to 20k instead of 10k) Changed the sensitivity of the coarse and fine knobs (R10 and R11) Used an LM4040 to create a 5V referenceRead More
Crusher
I was one of those guitarists who spend more time with his effect pedals, then with his guitar. I ended up exchanging my guitar for synths when it came to music making. Not really a surprise there, but my love of piling effects together into a huge unpredictable pile isRead More
FML – 4 operator FM percussion drone module
While doing research for the oscillator I stumbled – seems to be a common theme — upon these IC’s. The ICL8038 promises to be a stable oscillator with very few external components. It’s an obsolete product, but I could get a few of them via Ali-express cheap enough to experimentRead More
VCO-1 – The Oscillator One
Since Coolaudio started reissuing old IC’s used in various synths I always eyed the V3340, which is a reissue of the CEM3340 chip as used in many classic synths such as the Roland SH101, Prophet 5, Memory Moog and plenty of others. It’s, in essence, a fully featured 1V/oct oscillatorRead More
