Show HN: Replacing $5K industrial signal towers with a webapp [video] https://ift.tt/GaRAcM2
Show HN: Replacing $5K industrial signal towers with a webapp [video] I built SignalTower, a web app that recreates $5K industrial signal tower functionality using just a browser. Demo: https://signaltower.netlify.app The demo uses your phone's flashlight to prove the concept, but the same Web Serial/WebUSB APIs can control real PLCs and signal towers. Traditional setup: ~$15K (HMI panel + signal tower + licenses) This setup: $15 Raspberry Pi You can test it standalone or install it in GnokeStation by typing "install [signaltower-url]" in the terminal. Current state: Working proof of concept. Looking for feedback on the industrial control approach and potential production use cases. https://www.youtube.com/shorts/t-ROd1hx20I December 31, 2025 at 11:33PM
