Dual simple AD/AR Envelope – LMNC Design
The layout I use is based on LMNCs design, but I found that he put up some extended designs on his page: Here Info: Sadly I don’t have a schematic for this build. If I get around I’ll try to draw one.

Gate2Trigger – transistor design
This module like the other has a lot of uses.
4046 Squarewave VCO
I did a bit of tinkering on this one but sadly didn’t document it too well. For now this was my starting point and I’m sure it is not far away from my final build. The Mod input makes it a pretty freaky FM kinda VCO. Have fun with it. Link to CuSis Youtube Video […]
Bongo Drum Module – NLC Bong0
I really like the sound of this twin-t drum module. Idk if it is too useful for a lot of electronic music imo but it’s an intermediate build that should make you somewhat proud when you’ve done it. Link to the NLC project page: Here
6 Channel Trigger Sequencer – Hagiwo Build
This Arduino Nano Sequencer is working like a treat and I can’t recommend it enough. Link to the original project page: Here One rotary encoder and a button to interface with the tiny oled display a clock input and 6 channel outputs. ///—————-ライブラリの読み出し————————— //EEPROM用ライブラリ #include <EEPROM.h> //エンコーダ用ライブラリ #define ENCODER_OPTIMIZE_INTERRUPTS //エンコーダノイズ対策 #include <Encoder.h> //OLED用ライブラリ #include<Wire.h> #include<Adafruit_GFX.h> […]
Cheap Dual VCA – Transistor based VCA
This more or less passive design is from Bummbummsteffen. He designed it for his drumrack and it works okay but using his words ‘Theres some distortion in the output. Furthermore the design doesn’t work with negative voltages.’ I built two of them on one protoboard and even built one more for the portable setup.
Gate2Trigger – Dual G2T
This is another Bummbummsteffen Module that has served me well over the last months. I use it currently for my drum modules and sometimes for envelopes or to ping filters. A really neat addition to any system I believe. stripboard layout
A/D Envelope – Thomas Henry design layout by Eddy Bergman
This neat design works with a NE555 as well as with a 7555 IC – tested by me. Link to the great documentation of Eddy Bergman: Here! How to make it better? Maybe add a looping stage with another opamp? Maybe an inverter circuit?
2144 VCF – electrosmith submodule build
Like the others here’s the link to the electrosmith submodule page: Here The VCF has a cutoff and a resonance pot as well as cutoff and resonance CV jacks and the signals can be attenuated. Two signal inputs and one output make it a really versatile lowpass filter imo.
Dual VCA – electrosmith submodule stripboard build
This pretty easy build uses the electrosmith submodule : This
