Most DIY projects stay on the workbench because they look like science experiments. The OG DIY Smartwatch is the result of a nine-month engineering journey to prove that 'DIY' can mean 'Daily Driver.' After seven mechanical revisions to master SLA resin tolerances and light-bleed, I’ve transformed a bare ESP32-C3 circuit into a sleek, open-source wearable. It features a 350-nit IPS display, custom LVGL-based OS, and phone-synced navigation—all built for a fraction of the cost of a retail watch. We built it cheap, but we wear it proud.

I built HALF PILL a smart Wi-Fi enabled Pill Reminder using the Seeed Studio XIAO ESP32-C3 and their beautiful Round Display for XIAO.

This project demonstrates a long-range smart home control system built using RYLR998 LoRa modules, NodeMCU ESP8266, and Arduino Uno. Unlike traditional WiFi-based home automation systems, this project uses LoRa (Long Range communication) technology to enable wireless communication up to 5KM range under line-of-sight conditions.

By combining a vintage radio's sensitive front-end with modern SDR technology, I created a powerful hybrid receiver that offers both the nostalgic feel of classic hardware and the precision of modern software.

Project #12: Robotics - Web Server - Mk32

By combining the vintage aesthetics of a CRT oscilloscope with modern ESP32 hardware, this project proves you don't need dangerous high voltage to enjoy the classic look of a vector clock.

Project #28 – Sensors – Tilt Switch – Mk28

Project #12: Robotics - Camera - Mk31

its good

The simplest way to make a relatively powerful stereo Vacuum Tube audio amplifier with components that are easily available.

Weather Crow is an ESP32-S3 based weather station featuring an E-paper display that shows current weather conditions and forecasts. This initial release provides a complete solution for monitoring local weather with minimal power consumption through efficient deep sleep cycles. the project is under the MIT license, so you can modify or chage as you want!!
