That is exactly what this Raspberry Pi object detection project demonstrates. You can build a fully working object detection ...
Control it with your smartphone and view the underwater scenery through a browser. A sci-fi dream realized with an ESP32 and a 3D printer. The ESP-FLY featured in the previous [Kato RC #29] was a $30 ...
Operating systems are great things to have for general purpose computing, but sometimes they can just get in the way. There’s RAM overhead and processor cycles required for all that operating, after ...
This project is a hard drive emulator for your Atari ST using an inexpensive STM32 microcontroller and a SD card. The aim of this project is to be very easy to build, extremely cheap, reliable and ...
An ESP32 client that captures audio over I2S and posts WAV to a server. A lightweight Flask/Gunicorn server that returns JSON transcriptions via speech_recognition. Designed for deterministic embedded ...
The build: → ELEGOO UNO R3 → Arduino IDE for the firmware → Optical pulse sensor reading PPG (Photoplethysmography) off a fingertip → 16x2 LCD (I2C) to show live BPM → LEDs to indicate safe vs. unsafe ...
