Another one of my own designs. I was in need for a master clock that would display the BPM and could be adjusted with a knob. There aren’t that many out there that fitted my needs. So I made Littleben. It started out as a simple clock with 4 clock outs and 4 reset outs. Running on a Arduino mini the firmware grew and now it can do a lot more. It can divide clock, calculate a incomming clock and I’m still not finished in releasing firmware for it. I have plan for more functions. If you want to know more be sure to check out the menu on Littleben. If you want to build your own you can find it in my shop.

Another one of my own designs. The original design is made by Mutable Instruments and called Grids. It’s a drum trigger sequencer. When starting into eurorack I started out with a lot of drum modules. But had nothing to trigger them. I designed the Nanogris of the Grids schematics but used all thruhole parts and a Arduino Nano. It was quite the journey. I did some pcb’s design before but this took a while to get right. And even when I got it right I still could do somethings better. The Nanogrids is now on version .041 and I think I got all things correct now. More info about this module on this site (see menu) and of course if you want to build your own it’s on GitHub and in the shop
Well I can write a lot about this module, but I already did on different parts and topic on this site. I made this module myself based on Hagiwo design. Used his schematic, changed the DAC chip to a thru-hole type and made pcb’s and panel for it. It’s a nice little quantizer with slide function. You can find more information on it on this website. If you want to build your own be sure to check out the shop. It’s fully open source if you want to make the pcb’s and panels yourself.
I started out my eurorack with drum modules. It was more a drum machine then a synth. But when the hexinverters clap failed to startup and the snare wasn’t what I tough it would be I started building other modules. But I found myself always looking for more drum sounds. The snare and clap where missing quite a long time from my setup until Weston released the AD110. This would surely fit my needs for a good clap and snare, and it did. The modules also comes with a bass drum, cymbal and hithat. It’s a all in one drum machine. Based on the Korg DDM-110. It has some modifications but sound oldskool and good. The manual is well documented.
Difficulty to build: Medium, some may find it hard. Has multiple pcb’s, can take up some time but well ordered and spaced
I bought this module a few years back. It’s a great digital oscillator with a few trick up it sleeve. It has a Teensy on the back loaded with the firmware. I bought it when it was still made with thruhole parts nowaday it comes as a SMD version. I should still be possible to build by hand. If your looking for a new osccillator be sure to check this one out and not be fooled by being on the market for some time now.

Newer version are all SMD parts.
I don’t buy that many modules (unless it’s MFB) but this one I made a exception. I needed a good way to combine my rack with my DAW and this module is in my opinion the best to do so. I bought it second hand and only scratched the surface so far but recording my rack has never been so easy. The quality of the recordings is just amazing. I planning on using it to make some recording for the website while doing reviews of modules. I cost me quite a few buck but worth every penny.
Difficulty to build: No DIY
I just finished one of these. I found his post by accident on modwiggler. After seeing it I went into a rabbit hole for a few days. This baby is a small Daisy patch and open source. If you don’t know what a Daisy patch is… well these days a lot of modules come out that use a Daisy on the back of them. Daisy is kinda like a Arduino nano but build for audio DSP. This makes it a great miniature computer to program stuff on. I just build mine and still need to load some code on it. This module can be anything you make it to be, a FX unit, sampler, ADSR and more. Just about anything. It can be used in Guitar pedal be a complete synth or a eurorack module. It is used by Noise engineering, Knobula, PedalPCB and more. For more information on the Daisy just visit electrosmith.
Recursinging made a open source small module for eurorack. I can’t wait to program this puppy. Mainly as a FX unit or a sample player.
Difficulty to build: Hard mostly SMD. I used a SMT assembly when ordering the board.
I got this filter from a friend of mine. He just send the pcb’s and panels and a link for the bom. As we where both building it we found it had some error’s. After he emailed Cagey we discoverd he accidentally uploaded the old files and our board where made based on that. Knowing what the problems where we finally could build it. I was quite interested in this filter. It uses a chip that not many filters use and is used in some great sounding machines like the Synton Syrinx and Crumar Spirit. The filter it self is quite nice. It doesn’t go into that oscillation mode on resonance. I would even call it quite calm, smooth and subtle. But that can be very nice sometimes.
It inspired me to have a better look at the chip used in this baby and make my own filter. I’m waiting on the pcb’s to arrive so maybe more on that.
Difficulty to build: Medium/Hard
Well oh well this is a special one. It’s also still in the prototyping fase. The module is a random acid generator and can (also) be used to create basslines. I’m testing this module out and want to thank Budgie for sending me one of these. I still want to do a full build report and review on it. Hopefully I can find the time for that somewhere.
Some explanation and demo can be found here

I got this filter from a fellow designer. It’s still in the prototype fase and I’m one of the lucky ones to test it. It’s a really nice filter. It resemble the MS-20 filter when listening to it. It have to double check with Budgie is it’s based on that design. It has low pass, band pass and high pass output’s. It can overdrive the resonance quite a lot. I like this one and when it hits the stores be sure to check it out. Don’t know exactly why it’s call Greenfinch but I think Budgie names it’s modules after birds.
