Hardware documentation

Breadboard aufbau (made with fritzing)
The hall effect sensor + Preamp

There is a hall effect sensor placed right over the valve of the airassist.

This valve is opened to enable a static airflow as soon as a laserjob starts and is disabled when the job ends.


All states are now handled by the embedded system.

The Arduino only displays what the ELS sends it.

The arduino sends ibutton scans and pushbutton events.
