I wanted to make a widget where you can drag the pointer around and change your lighting color. I am assuming a specific configuration of lights. In particular, I am using 10 DFX VersaPars, all in a 6 channel RGBWAU configuration. I use QLC+ version 4 as my lighting control software. I initially tried using…
I’m working on a wearable heartbeat sensor project using the HW-502 and a Micro:bit. My initial configuration is using the Micro:bit for data collection and display, an Arduino to provide 5v power to the sensor, and the sensor is the HW-502 from the 37 sensors kit. As I was building this, I initially wanted the…
These are my tech notes from running an elementary school talent show with approximately 75 performers. Wiring Diagram Sound The primary requirement for our talent show was an audio amplification system. This consisted of: three wireless microphones, a digital piano, a phone to play music, a mixer, a monitor, amplifiers, and speakers. From my perspective,…
If you want to see the console output in a Linux terminal, you can use the following command: This is because it seems like the output console is bound to that serial port, so can’t be used for standard serial I/O. There appear to be libraries that could provide serial mirroring/pass-through, and would create a…
A digital xylophone with Micro:bit and neopixels! What a cool project! https://www.facebook.com/share/v/16bfPuo8Jy
I’m going to have to test this out later since it looks like what I’ve been trying to do with other LLMs with mixed results. https://byteshape.com/blogs/Qwen3-30B-A3B-Instruct-2507
A long time ago I built a quilt that had switches in each block, and this is very similar, though it looks like it uses capacitive touch rather than pressure, which mine used. Either way, cool stuff! https://blog.adafruit.com/2025/12/29/touch-sensor-quilt-block-the-raspberry-pi-official-magazine-issue-161-rpimagazine
This is just a fun use of a connect four game board as a musical instrument. It falls squarely in line with the original ideas that inspired Engineering Harmony.
I’m planning on building a foot-controlled musical instrument. First, I’ll need some floor switches like these: https://www.instructables.com/Floor-Switches-Mats/ I’ll be using some sort of microcontroller or microcomputer, like A Raspberry Pi or a Micro:bit, but I haven’t made that selection yet. It might be something more like this: https://www.instructables.com/Build-an-Easy-Floor-Piano/ I might use this for capacitive sensing…
