Play "Music" with stepper motors Part 1
Grumpy Developer Reading time:about 2 min Date: Language:english
Have you ever dreamed of creating an instrument that combines art and technology? I recently set out to build a motion control project that plays music using stepper motors, and what started as a crazy idea turned into a fascinating journey.
In a world where others had already explored this concept, I found myself without any guides or tutorials. But I'm a DIY enthusiast who loves challenges, so I decided to create my own version from scratch. The result is a system that can play music using midi commands sent through a USB serial interface, and it's all powered by an Arduino microcontroller.
In this project, you'll learn how to bring your creative ideas to life with motion control, and how to create a fully functional music player using stepper motors. From the hardware plans to the software instructions, I'm sharing my entire process so you can replicate it and start creating your own unique soundscapes.

Electronics to trigger Cameras, Flash and other things
Grumpy Developer Reading time:about 5 min Date: Language:english
Are you ready to create breathtaking water drop videos like a pro? I've developed a DIY system that uses an ESP8266 module, WiFi connectivity, and opto couplers to control the precise timing of water drops. With this project, you can create stunning visuals by synchronizing the release of water droplets with camera flashes and triggering high-speed cameras.
The system is incredibly versatile, allowing you to experiment with different LED lights, valve configurations, and even colored waters. You can use it to create mesmerizing effects like "drop-on-drop" or add an extra layer of complexity with multiple valves and electronics.
To get started, I've made the source code and electronics plans available for free on The Camera Trigger repository. If you're ready to unleash your creativity and push the boundaries of water drop videography, check it out!

Get ready to unlock the full potential of your Completely Insane Multi-Device Input (CIMDIT)! The latest update brings partial MIDI support, allowing you to control other instruments and software on your computer via MIDI routing. Imagine being able to play a synth with CIMDIT while also sending notes to your favorite DAW or controlling effects pedals - the possibilities are endless!
But what exactly is MIDI? In short, it's a protocol that lets electronic musical instruments, computers, and audio devices talk to each other in music-making harmony. With CIMDIT now supporting MIDI, you can take your music production to new heights.
Want to know more about what you can do with this powerful feature? You'll be able to send control messages like panning and modulation wheel adjustments, as well as create custom macros using pitch bend and more. Plus, our included profile generation page gives you a head start with some example configurations for all supported MIDI messages. Ready to unleash your creativity? Dive in to learn more about the full potential of CIMDIT's MIDI capabilities!
Creating a custom (car) Radio
Grumpy Developer Reading time:about 2 min Date: Language:english
The luxury of owning multiple old cars has led me down an interesting path - to create a modern radio system that caters to my nostalgic cravings while addressing some common shortcomings of current Bluetooth-based solutions. I'll be building a custom radio unit with features like FM radio, Bluetooth connectivity for hands-free calls and navigation, auxiliary input for external devices, and even DAB+ functionality.
But here's the twist - I won't be using pre-made, high-end components that compromise on design or cost. Instead, I'll opt for more affordable options and DIY it myself, leveraging popular breakout boards like the Si4703 Radio FM RDS RBDS Tuner Breakout Board and a F-6188 Bluetooth module.
The result will be a unit that's tailored to my needs, with a focus on functionality, simplicity, and even a dash of vintage charm. Will I succeed in creating the perfect retro-modern radio system? Only time (and a healthy dose of DIY expertise) will tell!

The author describes four modules of a keyboard project:
1. The brain, which is an Arduino Pro Micro providing USB connection.
2. A rotary encoder board featuring a CD74HC4067 breakout board for analog input.
3. A key matrix module with a 64-button capacity, requiring diodes to prevent ghost buttons when multiple keys are pressed simultaneously.
4. An analog multiplexer board using the CD74HC4067 chip.
The PCB layouts and electronics designs are available on the author's git repository, with updates including corrected schematics and compact versions of the rotary encoder and key matrix modules.
