  • Hacking was done:
    • Could not find driver for stepper, although a Nema 17 stepper was located which looks good
    • Ed prototyped tipper device.
    • Ian used an aquarium air value / servo combo which worked to dispense soft drinks with a gravity feed. Tube was quite thin, so flow rate was low
    • Mouse failed to lasercut a peristaltic pump thing
