A developer created a tiny game console based on an ESP32-S3 microcontroller that fits inside a 9.5mm antenna plug and connects to a TV via RF modulation, supporting games like Doom with Xbox controller input and PAL audio/video output.
BabyTalk enables offline speech-to-text and text-to-speech on ESP32 microcontrollers without cloud dependency, supporting English transcription and neural voice synthesis. The project runs on ESP32-S3 or ESP32-P4 with minimal memory requirements and works across C, MicroPython, and Erlang/Elixir, making it suitable for offline voice applications like LoRa radios and IoT devices.
A maker designed and built a wearable LED neon t-shirt in just a few days for a company event, using flexible LED filaments sewn onto black fabric with a stiff backing, powered by an ESP32 and various voltage converters. The shirt features a llama design on the back and text borders on the sides, with the filaments controlled through custom electronics housed in a 3D-printed enclosure.
Pluto is a natural language AI system that runs directly on microcontrollers with minimal memory footprint (0.5 MB RAM), enabling users to control hardware through voice commands instead of traditional programming. It supports multiple platforms including Arduino, ESP32, and STM32, and can manage GPIO, PWM, I²C, SPI, UART, and sensor operations without requiring cloud connectivity. The proprietary C++ framework is distributed as pre-configured hardware rather than public software.
