Virtually ride indoors with Google Street View and bluetooth bike power meters (Web Bluetooth API)

Open-source Art-Net / sACN (E1.31) → DMX512 gateway for ESP32 / ESP32-S3 / Ethernet. Live web UI shows all 512 channels in real time, flags console conflicts, and drives galvanically-isolated DMX. Flash from your browser, no toolchain.

PN532.js is a JavaScript library for PN532 base on Web Bluetooth and Web Serial.

Web USB Flea-Scope™ GUI/deep-dive UI and general-purpose terminal emulator (well, without actual emulation :-)

🕹️ A collection of awesome Web Serial libraries, resources, and shiny things.

A p5.js library for controlling the AxiDraw pen plotter.

[ThatProject] ESP32 LoRa GPS Data Viewer

Web-flashable Reticulum LoRa repeater firmware for nRF52840 + SX1262 boards — an easy path from Meshtastic/MeshCore to a Reticulum transport node

A webapp to print using the Phomemo M02 printer.

Browser-based Reticulum messaging client — encrypted LXMF chat over LoRa via an RNode (Web Bluetooth / Web Serial) or to rnsd over WebSocket. No build step, runs on GitHub Pages.

A fully autonomous AI agent that runs on a ESP32 microcontroller (S3 and P4) — tool use, persistent memory, cron scheduling, multi-channel messaging, all on-device with modern web UI. Cloud-backed persistence (S3-compatible) protects your data from flash wear and reflashes via transparent write-through replication. Works with any LLM provider.

The Ultimate SudoPad. A programmable RP2040 macro keyboard with OLED.

Agents delivered by light: an LLM compiles a tiny program off-chip and beams it by screen-light to a radio-less Arduino that runs it forever, offline. Live at beam-claw.com

🚀 A free Cloud IDE for Arduino & ESP32. Write code in the browser, compile remotely via GitHub Actions, and flash firmware directly to your board using the Web Serial API. Supports multi-file projects, library management, and live build logs.

URDF, robot arm, voice control, and embodied AI workspace with web visualization and Web Serial control.

TypeScript driver for the LabeLife app printer family — ~95 Aimo/Quyin OEM thermal label printers (Phomemo, Munbyn, Wagtail, 123inkt LW650XL PRO, …) over TSPL II & vendor ESC/POS on Bluetooth, BLE, TCP-9100, and USB.
