Glitchstorm is an Arduino powered byte beat generator. Arduino, if you are not familiar, is an open source hardware programming platform. Rather than surf the web and send email, you can use Arduino to open your garage door, and flash your favorite color of LEDs, or in the case of Glitchstorm, output quasi musical audio.…
Here’s another epic pedal build. The Lovetone Doppelgänger is a phase shifter with lots of extras. It has 4 phase shift stages and two LFOs and options for all of this. The Quadratron is not a direct clone of the Doppelgänger. It’s faithful to the original but makes a few changes. Both are four stage…
Been working on this Eurorack drum module. This is a pretty epic kit : https://weston-precision-audio.myshopify.com/products/ad110-analog-drums-panel-pcb-set
RunOffGroove.com is one of my favorite sites for original stomp box inspiration and innovation. I built my first projects using the schematics and layouts there. The ideas presented are innovative. I’m very impressed with the UBE Screamer and 22/7. You can find PCB projects for those here! The Ruby and other projects are DIY staples!
Just got some new boards from PCBWay.com. These are RunOffGroove’s 22/7. This is a Big Muff built around MOSFet inverters in place of the Bipolar transistors used in the standard Big Muff. This is a great sounding Big Muff. If you’ve built Big Muffs in the past you should try this one. The tone control…

After my last couple projects rehousing new circuits in Boss enclosures I was left with several DS-1 PCBs. These were populated with some or all of the parts! I decided I couldn’t let these go to waste! If you’re interested to see what was rehoused in Boss enclosures check these out: 1981 DRV Burns Buzzaround…
This is a 6 voice analog drum module based on the Boss/Roland DR110. I saw this thread over on Mod wiggler. It looked like a fun module that I could get some use out of. Weston Audio has a few interesting Eurorack modules. They offer the AD110 as a kit! The kit comes with three…

Here is a build of the Morbid Fur fuzz. There were a few errors in my first version of this PCB. All my fault. I had these boards manufactured at PCBWay. com. They do great work and have many options to choose. Like solder mask color. I wrote about their service in more details in…
I have been planning to work on some Eurorack projects. Turns out it’s hard to find the correct jacks, or at least the PCB mount variety. I got a few on Aliexpress to experiment with I’ll talk about these in a future post. Turns out Thonk has the jacks I’m looking for. I had to…

I entered my PCB design in the PCBWay design contest vote for me! https://www.pcbway.com/project/shareproject/Super_Frequency_Harmonic_Square_wave_distortion_1.html This is a PCB for Tim Escobedo’s Ugly Face. Anyone that hasn’t built one of these you should try it. You won’t play it on every song but you when you do people will notice! Here’s a picture of the board…

I designed this PCB for Tim Escobedo’s Ugly Face and had it manufactured at PCBWay. I used Eagle PCB to design the board. The process was not hard with a little research. I started by finding the PCBWay Eagle DRU file. This tells design rules that PCBWay will accept. This includes the minimum trace size…

Demo of the Green Russian clone. It’s got a lot of bass! Built this from a Madbean PCB.
