KiCAD 7 custom footprints

Sometimes we find ourselves working on a schematic and find that we don’t have a footprint for the part or component we are using. So we think, OK someone elese probably ran into this issue so why not check the internet? Why not? If someone else has done it why re-invent the wheel right? So, you find your part, place your component and then ship your files for manufacturing. A week later you get your boards only to find that the footprint is off.

Microcontrollers: Gate and trigger output signals

Introduction Hey, friends! Welcome back to our microcontroller adventure. In this episode, we’re diving into the world of output signals. We’ve already explored input considerations, and now it is time to start looking at output signals. Today we will cover gates, triggers and some simple LEDs. If you are wondering what these are: Gates and triggers are control signals used in electronic music to initiate and control events such as note playback, envelope shaping, and rhythmic patterns.


UMIDI A couple of years ago, I made a module for my eurorack that allowed me to use my Korg ES2 sampler to trigger drum modules. The idea was that it could have a TRS MIDI input and gate outputs. The module has been incredibly useful, but I want more! The Teensys are not cheap, and this project used a Teensy 2.0++ so I thought why not use an STM32 Blue Pill instead and do it at a fraction of the cost.

Microcontrollers: Input Signals

Inroduction Greetings, from the southern hemisphere! Today we continue our exploration of microcontrollers in the eurorack environment, focusing on the critical aspect of receiving external signals. Why is this important? Well, these signals, whether from potentiometers, buttons, or other modules, serve as our bridge to interact with the programs running on the microcontroller. There is plenty of material out there on hooking up potentiometers and buttons out there. Trust me you don’t have to look far.

Dual ADSR / VCA Combo - Part 2: Build Journey and Retrospective

Introduction Hey, what’s up? Juan here, and we’re diving into the second part of our Dual ADSR/VCA combo module. If you missed the first part, check this link for a recap. Today, we’re not just wrapping up the project; we’re reflecting on the journey. Build Highlights Alright, let’s kick things off with a speedy recap. As you recall we combined an ADSR circuit together with a VCA circuit so that we can run audio and a gate signal in order to shape the audio signal coming out of the module.

Setting Up Your Microcontroller Development Environment

Introduction Hello again! As we gear up for 2024, I’ve got some exciting projects in the pipeline. While I’m waiting for parts to arrive, I thought it would be a great time to help you set up your microcontroller development environment. Having a robust Integrated Development Environment (IDE) is crucial for efficient software development. An IDE, much like our homes, provides us with essential tools and features that streamline our workflow.
