Waveform Magazine Meow Mixer - DIY Build

Completed Meow Mixer - Front

Every quarter we receive a new issue of our favorite magazine… Waveform. In this issue (Summer 2021 – Issue 6), a small 2HP module called the “Meow Mixer” was featured alongside a new modular case kit (aka. The Mewsic Box) as the featured project. The Meow Mixer is a 3-channel powered Eurorack module that has 3 inputs with attenuation, and 1 summed main output with an output volume control.

As with every DIY project that Waveform Magazine releases, the Meow Mixer was unique in that it could be used in conjunction with other DIY projects that Waveform released. This sounds confusing we know … but stick with us on this build and we will explain everything in detail. So, without further ado, let’s jump right into the build of the Waveform Magazine Meow Mixer!

Waveform Magazine Catwalk Cattenuator - DIY Build

As we tackled the Waveform Magazine Cattenuator, it was now time to tackle the new LPG/VCA. Like the previous build and the Mini Mult Catwalk, these modules take up about 12HP of space in your rack. Their footprint is small and their impact is huge. As previously stated, Waveform Magazine is on point with their Catwalk series. In case you have missed any of the previous builds or reviews, check out the quick links below to learn more.

Project #5 - Catwalk LPG and VCA

Let’s get onto the builds shall we? Building the Catwalk VCA or the Catwalk LPG is relatively easy. The most difficult part of this build is assembling the vactrol or optocoupler as its sometimes called. An opto-isolator (also called an optocoupler, photocoupler, or optical isolator) is an electronic component that transfers electrical signals between two isolated circuits by using light. 

You will be putting together 2 of the optocouplers for this set of Catwalks, so turn on your iron and get ready to dive right in.

Waveform Magazine Catwalk Cattenuator - DIY Build

Issue #5 of Waveform Magazine is hot off the press and is steaming with all sorts of amazing modular goodness. With its reviews, interviews, industry news and modular kits, it is no wonder that so many modular enthusiasts look forward to each issue.

Since the magazines first release, we have been building the WF kits as soon as we get our hands on them. Here are the previous projects that Waveform has released and we have had the opportunity to build/review.

Issue/Project #1: PT2399 Delay

Issue/Project #2: The Gateway Oscilloscope 

Issue/Project #3: The Switchenator 

Issue/Project #4: Catwalk – Mult, Mini Mult and Ribbon 

Project #5 - Cattenuator!

As with all of the previous builds, the quality and the ingenuity continues to get better and better. Waveform really threw everyone for a shocker with their “Catwalk” series from Issue #4, being that neither of the projects took up any space in ones rack (hence the name “catwalk”).

Issue #5 is no different and we are fortunate to have another x3 Catwalk modules (actually 4, the Catwalk Attenuator contains x2 of the same modules). With all that being said and done, let us get on with the builds so you too can see how cool these new Catwalk modules are! If you would like to bypass and jump to a specific Catwalk module, use the quick links below.

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!).
