"Crum Drum is a 4-voice drum machine with built in randomisation and probability based sequencing designed by NYSTRÖM

Rhythms can be created and manipulated using the internal random sequencer or externally via MIDI USB. Press the beat button to generate new rhythms, adjust the probability to create continuous variations, and increase the randomness to modulate the sound of your beats! Generated sequences can also be sent out via MIDI and Crum Drum can also sync via analog clock in and out.

Albert Nyström Made a Drum Machine for $70

video upload by Albert Nyström

"Here's a Drum machine I designed and built over the last 3 months using a Teensy 4.1 as the main brain.
The total build cost was about $70, 30 of which was the Teensy itself.

I'm pretty happy with how it turned out and I´m considering making a 2.0 version in the future that will be for sale!

Here's a link to the Code, Schematics and more information about the project:

Tiny Bug - a mini glitch Synth!

video upload by Albert Nyström

"This is a little synth I recently built.
It´s kinda based around an Atari punk console, but I added a few bits and pieces to make it more fun and experimental.

Pretty fun to just mess around with and make some noise!"

Spaces - a DIY-Synth live session!

video upload by Albert Nyström

"This is a live recording using only my homemade synths. all sounds you hear comes directly from my own synths, except some reverb and delay. The only equipment used that I didn´t build myself is the Digitakt that acts as a sequencer as well as an audio interface.

The modular system plays the arpeggios & all percussion.
The analog Monosynth plays all bass stuff.
The Guitar-synth plays all lead sounds.

Hope you enjoy!"

Some additional details from the comments:

On parts: "My best estimate is around $180 USD, ~70 of which was the Keystep that I used for the keyboard."

On design: "I built everything myself, but took inspiration from exsisting schematics. The filter is based on Mortiz Kleins vactrol VCF, the envelopes are based on Thomas Henrys 555 envelope and the VCOs are built around the AS3340 chip! The effects are the only part I didn't build myself, Search for 'dsp 100 reverb' on aliexpress!"

Homemade analog Synth-Guitar!

4:04 Walkthrough

"Fully analog, fully homemade guitar-synth
Built from scratch, based on a few different schematics aswell as a few own designs for some of the functions.
The pitch is controlled by two soft-pots tuned a 4th apart, just like a guitar.

The body is mostly made of stained plywood and the knobs are made of dowels that i cut and sanded to size!

The synth is accompanied by a couple of beats I made on my digitakt!

Hope you enjoy!"
