Open source automatic blast gates
Assembled electronics + gate https://preview.redd.it/r85jwkdtyqsh1.jpg?width=4416&format=pjpg&auto=webp&s=f370bc10a1f95078883017ce7e723c3699e77514
This is more woodworking adjacent, but I checked with the mods first.
I've just released my opensource (hardware and software) automatic blast gates, "HonkLock". https://github.com/TemuWolverine/HonkLock
* 3d printed ball valve gate design
* Non-invasive tool detection using magnetometer to detect current
* Using cat5/5e/6 to connect the sensor (data+power) to the brainboard allows runs up to a theoretical 30m - I've only tested up to 10m - allowing the gate and sensor to be far apart. It's just using the cable, not actually ethernet.
* Custom PCB for sensor and brain boards - kicad https://github.com/TemuWolverine/HonkLock/tree/main/PCBproject & gerber https://github.com/TemuWolverine/HonkLock/tree/main/productionfiles provided.
* Uses a cheap ESP32-S3-SuperMini for the microcontroller
* Fusion 360, STEP https://github.com/TemuWolverine/HonkLock/tree/main/CAD and 3MF https://makerworld.com/en/models/3370684-honklock-automatic-blast-gate-with-tool-sensor#profileId-3833561files for the gate (currently 5" to match my system, but thats what the F360/STEP files are for!)
* Currently HonkLock uses HomeAssistant for coordination of gates, which has the benefit of allowing any remotes/switches (like Ikeas zigbee/thread remotes) to be used for manual opening/closing.

It turned out better than I expected - not only are the gates more airtight than I thought they'd be, the sensor response is crazy fast - finger was still on the power button on my combo machine and the gate was already open.

This HonkLock project looks super practical for a workshop setup! How does the tool sensor integration work in practice?
