Electronics Projects
Alongside product testing, this channel documents original electronics projects from first principles: schematic design, PCB layout, firmware, and assembly, built the same way a working engineer would approach them, with the mistakes and debugging left in rather than edited out.
This category is the home for those builds: microcontroller projects, custom PCBs, test equipment builds, and one-off tools designed to solve a specific problem on the bench. Where a project uses a downloadable schematic or design file, it’s linked directly from the video’s page.
SDG #365 Reverse Engineering NAD D7050 OLED Replacement for IPS TFT
Decoding the NAD D7050's obsolete SSD1355 OLED protocol with a logic analyser, then driving an SSD1351 OLED and ST7735S IPS TFT as replacements.
SDG #360 Zero Crossing Detection and PCBWay 3D Prints
Testing PCBWay nylon PA12 and clear resin wall mounts for a Waveshare 4in ESP32-S3 touch dimmer, plus lower-power zero crossing detection options.
SDG #357 RGB Meteor Shower LEDs Build using ESP32 and WLED
Custom meteor shower Christmas lights built from WS2812 LED PCBs, ESP32 controllers running WLED, acrylic tubes and 3D printed weatherproof caps.
SDG #349 Testing of WLED to LED Lighting reverse engineering
Reverse engineering ArcDot garden LEDs: why the ESP32 UART can't do 9-bit data, and how a dsPIC33 DMX bridge makes WLED drive them.
LED Garden lights shenanigans #electronicscreators
Progress update on a DIY LED garden lighting install: 74 lights wired in, the controller protocol reverse engineered, and a custom PCB coming next.
SDG #348 I bought over £30k of LED Lighting to reverse engineer
Teardown and protocol decode of Pulsar ArcDot2 LED pixels and the ArcDotDriver80 controller, including an RS485 repair and auto-addressing capture.
