Eurorack Hardware (EH) Modules - DIY Builds

Spring is on its way and it is the perfect time for new modules to be hitting the market. We were stoked when the gang over at Synthrotek recently announced that they going to carry a new set of modules made by a relatively unknown company known as Eurorack Hardware (EH). 

A total of 5 new modules in all, the OR, E-OR, ATT, AMIX and RING are going to make a splash on the modular scene.  With that being said, we are excited about taking on the new DIY Kits from Eurorack Hardware (EH).

Who is EH? Who makes these new modules?

Eurorack Hardware (EH) has actually been around awhile, you just kinda know them in a different persona. Have you ever heard of Division 6? What about the Dual Mini Sequencer? Eurorack Hardware (EH) was founded by Scott Rise, who is also is the director of Division 6 Labs. Division 6 manufactured the infamous Dual Mini Sequencer and they produce other synth circuits and video game hardware mods.

EH are mainly known for manufacturing hardware for eurorack modular systems. They specialize in various rails, brackets and screws, and pretty much anything you would need to build a custom rack.

Upon partnering with gang over at Synthrotek the world was introduced to the OR, E-OR, ATT, AMIX and the RING. The five modules are described below, each with their own time lapse build, build notes and gallery.

Let’s get one with the builds…

Synthrotek DIRT Eurorack Module - DIY Build

A classic Synthrotek filter, the DIRT is a 4HP module that is a necessity in any modular system. We actually have two of these and forgot to do a build video for the first… so guess what we did? You got it, a time lapse build of our second little module with grit.

What is the Synthrotek DIRT? It is described as a low-pass filter or effect module for eurorack modular systems. It has three knobs all which coinside with different variables of tone/sound. It can be used for filtering, ring mod effects, wave shaping and even harmonic distortion (which you can hear in our audio samples below).

Let’s get on with the build shall we?

How hard was the build?

The Synthrotek DIRT is a pretty simple build actually. It took about an hour to complete with a few stops along the way to change the tunes and grab some knobs for customization. 

One thing you want to make sure to pay attention to is the polarity of the caps (as usual) and the values of the potentiometers. There are only three pots, but all three have different values. The nice thing is that Synthrotek provides a great assembly guide and packed BOM for your reference. When referring to the assembly instructions, you will find that there are actually three different versions of the Synthrotek DIRT. A 9V standalone version (for pedals) and 2 eurorack versions are available. (At the time of this review, PCB version 2.2 is the current version).
