Upload Audio to RC-500

I have a Boos RC-500 loop station. It’s great, I have to say. I’ve started my Pico MIDI project to create a MIDI pedal for it. But I digress. One of the things that’s a bit annoying is that it supports only a particular format for the audio files. If you want to upload MP3 […]

Micro Thunder Boost – Noise

I continue working on my micro boost effect. I wasn’t entirely happy with the noise performance from the first take. I wanted to investigate a bit more. How did it go? See the video. Links can be found in section where I’m trying to make sense out of all of this ?. Intro As a […]

PICO MIDI – Expression Pedal

Let’s continue working on Pico MIDI – a Raspberry Pi Pico based MIDI pedal. In my previous posts I covered how to send MIDI commands and how to support footswitch and LED. Today, I’ll use an expression pedal to control Digitech Whammy. In earlier posts I also used RC-500 Boss looper, so make sure you […]

This was quite a long post, especially because it covered how to actually control two pedals. In that previous post I controlled Boss RC-500 looper and Digitech Whammy. It was a […]

MIDI Control Pedal – The Beginning

I’ll call this pedal Pico MIDI because I’m using Raspberry Pi Pico for this. And it’s also of diminutive size ?. I recently posted a teaser, took me maybe a day or two to get that up and running from scratch without really knowing anything about MIDI. While I’d love to brag about this achievement, […]

Clíodhna – PCB Version

All the work is done for our Super Screamer, or is it? What if I do a PCB version of this, just for fun? PCBWay said they’d gonna send me some prototyping boards for free right around the time I was finishing the pedal. So I said why not, let’s design a PCB version of […]

Simple Phaser – Playing with LFO

And in true spirit of overdoing it, after playing with our phaser components, let’s look into LFO. For previous posts have a look here. As usual you can skip to the video and come back later for diagrams. In this article I cover some modding options for LFO, I do some SPICE simulation and then […]

Simple Phaser – Experimenting with All-Pass Filter

This is getting a bit complex for a simple Phaser ?. After a long way coming back to the original schematic, it’s time to do some experimentation. In this article I cover what might be useful to try out modding, I do some SPICE simulation and then I breadboard another version of the phaser so […]

Clíodhna – Demo 1

The pedal was built ?, super screamer is ready to be tested. There are 192 useful options, but in this demo I managed to try out just 5. It is certain that there will be more to follow. The epic journey is documented here. Let’s get down to business ?:
