# davidmonterocrespo24/velxio > Open-source multi-board microcontroller emulator and circuit simulator: write Arduino C++, MicroPython, ESP-IDF or Python, compile and run it against real CPU emulation with 150+ electronic components right in your browser. - Magnitude: 2.2 out of 10 — Steady - Stars: 3,105 total · +3 stars measured 2026-10-08, 10:59–11:52 UTC, ≈ 11 by evening - Star trust: star growth looks organic - Category: Hardware, IoT & robotics · Language: TypeScript · Created: 2026-03-03 · Last push: 2026-10-05 - GitHub: https://github.com/davidmonterocrespo24/velxio · Homepage: https://velxio.dev · Page: https://gitnova.dev/en/r/davidmonterocrespo24/velxio ## Useful for - Test an Arduino Uno or ESP32 sketch without buying hardware - Build a circuit with sensors and a display on the virtual canvas and run it - Self-host the emulator via Docker for teaching or CI ## Why it’s here - Star-counter measurements on 2026-10-08 (UTC), 10:59–11:52: 3102 → 3105 stars (+3). This is the change over that interval. - Estimated end-of-day forecast: about +11 stars, using observed gains and the previous day. - Over the last two days the pace is 1.7× that of the previous week and a half. - GitHub Trending TypeScript today: #16, +36 stars. ## Star trust Star growth looks organic. Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer. ## Numbers - Forks: 319 - Issues and pull requests: 380 - Watchers: 24 - Average over the last week: 14 per day - Usual pace: 10 per day - Stars in the last hour (measured): 3 - Latest release: v3.0.5 (2026-09-02) ## Stars per day, last 30 days (oldest → newest, today is partial) 2026-09-09 … 2026-10-08: 8, 12, 4, 10, 11, 13, 13, 9, 9, 10, 2, 12, 10, 11, 7, 7, 8, 10, 18, 16, 8, 11, 10, 11, 6, 9, 14, 20, 27, 3 ## Spotted in now - GitHub Trending TypeScript today: #16, +36 stars ## Similar by description 1. **facebookincubator/muse-gadget-sdk** — 5.4 · Cooling · Hardware, IoT & robotics · C · +105 stars measured 2026-10-08, 00:02–11:46 UTC, ≈ 187 by evening SDK and firmware for building your own Muse gadgets on ESP32 or Linux: displays, buttons, sensors and audio that pair with the Muse app on iOS and Android. Full card: https://gitnova.dev/en/r/facebookincubator/muse-gadget-sdk.md --- Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score. Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast. Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
