Cristmas tree
Yuri Vorobets Nov 19,2025
The WS2812D-F8 is a high-tech, digitally programmable 8 mm RGB LED that’s individually addressable in daisy chains of up to 255 devices. In this 3D Circular Christmas Tree Project, 36 of these devices can be controlled externally or by an onboard Arduino Nano ESP32. The light effects are astonishing — you can’t miss having this illuminating Elektor kit for the Holidays!

Audio reactive glow LED wristband/bracelet with NFC / RFID-Tags
Loeffler Nov 19,2025
A rechargeable glowing wristband that reacts to music, powered by a thin LiPo battery. The TPU band has 15 LEDs inside. The animations are driven by audio analysis and controlled with an ATTiny85 processor.Why did you make it?I like electronic music events and festivals and my wife likes to dress up so I wanted to bing this together. I enjoy the synesthetic aspect of sound and light in a good club and so am I always trying to make the lights dance.Technical detailsAdjustable diameter: 5 - 8...

ILDAWaveX16 | StanleyProjects.com
StanleyProjects Nov 17,2025
ILDAWaveX16 is an open-source, high-resolution, wireless laser DAC with SD-card playback, network control, and ILDA output.Traditional laser DACs are often expensive, proprietary, or limited in flexibility, especially for those who want to experiment with laser systems, build custom projectors, or interface with low-cost driver kits.The goal of this project is to create the "Arduino of laser DACs" - a flexible, hackable platform for makers and enthusiasts that can serve as a foundation for any D...

SirenSense Ambulance Detection System
TKR Nov 16,2025
Project Overview: SirenSenseCheck out my youtube video to understand better how the device works ! https://youtu.be/NpQYkkEUuDsI live in a busy city where driving during rush hour is a daily reality. I noticed that when an ambulance is nearby, I often only realize whether it is behind or in front of me a few seconds before it passes. Many of my friends face the same issue; because our roads are congested and filled with buildings and tunnels, sound echoes become a major problem. This is the prim...

How to Make a Digital Clock on a Vintage B&W TV using Arduino
Pavleski Nov 07,2025
These days I accidentally came across this small retro Black and White TV with a built-in Radio, so I immediately decided to make some simple useful device with it. Of course, first I decided to check its current condition and functionality.  Let's examine the Radio receiver. As far as I can see, this part of the device is functioning normally and the only thing that needs to be cleaned is the volume potentiometer, possibly with some contactor spray.Now let's move on to the TV receiver...

3-axis stepper motor controller with CNC pendant connectivity
Curious Scientist Nov 07,2025
In this article, I show you the updated version of my motorized microscope. In one of my older videos, I introduced my motorized microscope and explained all the principles. Now, I show you the updated version. The main feature is that I incorporated the recently introduced CNC pendant into the system. Since the CNC pendant operates at 5 V and it also has a lot of wires, I decided to expand my previous board and make it compatible with the pendant. Apart from this step, I also did other things t...

Xbox Controller with ESP32
Arnov sharma Oct 31,2025
Greetings everyone and welcome back. here’s something I’ve been really excited to share.I’ve been working on a simple but powerful setup that connects an Xbox controller to an ESP32-C6 DevKit over BLE and displays all the input data live on an ILI9341 SPI screen. It started as a way to visualize controller input—buttons, triggers, and analog sticks—in real time. But once I saw how responsive it was, I realized this could be much more than just a visualizer.The real reason behind this build is a ...
