Hackerboutique DESTRUCTO – DIY Build

Hackerboutique DESTRUCTO- DIY Build

Social media is a place where many things can happen, both good and bad. One can also find some true gems in the rough as they scour the internet for new and exciting modules.  In our continued search to find unique eurorack modules, we stumbled upon a post about a new module called the Hackerboutique DESTRUCTO.

Posted by a gentleman by the name of Luis on a Synth DIY group, this VCF was a module with some serious balls… and we had to have it. 

Quick Link:  DESTRUCTO BOM

DESTRUCTO Glow!

As we were used to building kits, we were anxious to get our hands on this build. This kit was comprised solely of a panel, PCB and a pentode tube, which was unlike any of the other kits we have built in the past. A quick message and PayPal transaction later and we found ourselves anxiously awaiting our panel and PCB to arrive. This build was to be our first “sourced” build, meaning we had to track down all the components needed to build the module (the BOM is located above).

Luckily, we had just completed our Synth DIY Parts Locator, so we had some direction to start in. Luis also created a Facebook group for his Hackerboutique DESTRUCTO builders. This page became our go-to for anything related to the build… (we even gained a few new friends!). 


Synthrotek OBEY – DIY Build

Synthrotek OBEY - DIY Build

OBEY - Completed Front

Coming in hot this month is our build of the Synthrotek OBEY eurorack module. This dual-function module is one half envelope follower and one half attenuverter or offset generator.

On one side of the module, the OBEY can take inputs from piezos, guitars, drum machines and even microphones to trigger an envelope or gate into your eurorack system. The other side of the Synthrotek OBEY can attenuvert voltage sources in both positive or negative values (up to 2x times), giving this tiny module some hell of an impact on your performance/recordings.

Born from the Synthrotek nano series of modules, the OBEYs footprint is only 4HP wide. It has 4x LED sliders that control the various two sides of the module. Now, judging by our description, it seems overwhelming and complicated to use. It is not. Synthrotek has provided a lot of documentation and there are several YouTube videos out and about that show the OBEY being utilized.

NOTE: You can access the build docs and the manuals below in our “Quick Links” section below. 

Let’s get on with the build shall we?

Upon unpacking the module, you will notice that it comes with 2x PCBs and 1x panel. Set the smaller of the PCBs aside (it’s the control board that you mount jacks, sliders, etc to) and pick up the logic board. This is where we will start the build process.

Division 6 CEM3340 VCO – DIY Build

Division 6 CEM3340 VCO - DIY Build

Completed CEM3340 Front

Summer is in full swing and we were craving some new oscillators to add to our modular rack. This need was fulfilled by Division 6 labs and Synthrotek with the new Division 6 CEM3340 VCO.

This voltage control oscillator is based off the famous Curtis 3340 IC which has been around for quite some time and have been utilized in many legacy synths.  Our build of the Division 6 CEM3340 was a quick and easy build and is recommended for anyone just getting into modular DIY. 

What is the Curtis 3340 IC?

Many synths today utilize chips that mimic the famous Curtis 3340. While this chip is no longer manufactured in mass volume, there is a few places that still sell the chip. What makes this chip so special is it is a self contained, precision voltage controlled oscillator. 

NoteThe chip used in this kit is not an original Curtis 3340 IC, but it’s damn close!  

It features both exponential and linear control scales and up to four buffered output waveforms. ( triangle, sawtooth, square and pulse). They do not require a temperature compensation resistor because they provide their own compensation. Multiple control voltages can be mixed within itself.  


Rat King Modular GATES – DIY Build

Rat King Modular GATES - Eurorack Modular Build

As summer draws near and the hot weather rolls into California, it’s an optimal time to stay inside and catch up on some DIY modular kits.

When we heard that Rat King Modular was releasing a new module named GATES, we immediately hit up our friends at Synthrotek and ordered one up as soon as the kits were available. (The module had been released as a fully assembled version about a month prior and we were anxious to finally get our hands on the kit version).

Within a few days, the kit arrived and it was time to get busy building the Rat King Modular GATES!
