FRUKU Evi – DIY Build

FRUKU Evi - DIY Build

One of our favorite manufacturers, FRUKU is at it again with the release of his Evi module. In only 2HP, the FRUKU Evi is an envelope follower and signal inverter, meaning that you can plug any audio signal into the module and you will output an inverted envelope. What can this do? 

Well, it can add some spice to your signal routing and bring some flare to those beats you oh so desire. As one of our first builds of the fall season, the Evi was a perfect module for us to get our hands on. Let’s get on with the build.

FRUKU Oktra – DIY Build

FRUKU Oktra - DIY Build

As the fall season is upon us, we found ourselves going through our backlog of modules and came across the FRUKU Oktra. We have had this kit for some time, and now it was finally time to bring it to life. The Oktra has four independent outputs which can be controlled simultaneously with one knob (Macro Knob).

The four outputs all feature an attenuverter and two output sockets. If you also plug in an external signal, the macro knob is then bypassed and the module will function as a attenuverter/multiple. Sounds fancy eh? Let’s get on with the build shall we?

FRUKU B0B – DIY Build

FRUKU B0B - DIY Build

While there are many 808 Kick modules on the market, none are quite like the B0B from FRUKU, a designer out of the Netherlands. The B0B is FRUKU’s first solo module and all we can say is that it packs one hell of a punch.

Now, you might be asking yourself, where have you heard the name FRUKU before? A few months back, we built and featured the Veratrum, a new module by Reverse Landfill and guess who… FRUKU! 

The B0B is unique in that even though it is an 808 kick drum, it has a clipping parameter that accepts CV to control the amount of grit you want to add. The module features a decay, tone and volume pot as well. It’s black panel mimics that of the Veratrum and a lot of the modules produced by our friends at Reverse Landfill.

BEFACO KICKALL Eurorack Module – DIY Build

BEFACO KICKALL Eurorack Module - DIY Build

Befaco Kickall Packaging

As we head into the summer months here at fiN Studios, we take on our second build of the month … the Befaco KICKALL Eurorack Module. 

The KICKALL is a 6HP compact synth voice that features damn near everything you need to make a big fat KICK sound. This module is a powerhouse. It contains a VCO that tracks voltage per octave, an aggressive wave shaper and has the ability to use CV to control envelopes and pitch.

CV is controllable from Sine to Square wave shaping and the envelope decay for the main VCA is also CV controlled. So, what does this mean?  It’s a badass kick drum synth! 

What about that design?

Before we get into the logistics of the build, we want to take a moment to appreciate the Befaco KICKALL dual PCB layout. As a pretty complex and time consuming build, the two PCBs, once joined are a tight fit.  One would question how they did this so well, but designers uncanny knack to make each piece integrate with the other is amazing. You have to take a step back and appreciate its ingenuity and design.

This can also make for a difficult time for the novice DIYer. You have to be precise with your soldering points. Even as a more experienced builder, we took the time to finesse the module PCBs together.  The main thing here is that you want to make sure that you have no high tips in your solder points as they can short the boards or cause unwanted issues.  With all that being said, let’s get onto the build…
