Hardware
Consists of:
- Seagate Dockstar (because the raspberry pi SD-cards died several times)
- Arduino
- RGB 16x2 LCD
- OneWire (iButton suport)
- 1 Button
- a 6-Port Network Switch
Software
dockstar linux distro from usb stick
Node.js Server / Database
Arduino code (because there was a spare arduino laying around..)
How
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.
Protocols
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.
