Summary

• Review of last weeks meeting, progress during the week
  • Michael's optics arrived + soft drinks dispenser thing
  • Ian has a design for some soft drink dispenser
• Michael showed the design of a peristaltic pump design, much of which can be laser cut
• Mouse described Seb's progress and showed CAD drawings
  • Alternative bearing idea: from office chair (good idea Michael!)
• Summary of components left to prototype / design
  • Carbonated dispensers
  • Squirters
  • Pinch valves
  • Lemon slice
  • Measuring mass of drink to control amount of mixers

  • G&T
• Mouse talked about stepper prototype thing
• 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

Action Items

1. Mouse: meeting write-up, finish contact with EMF organisers re: drinkahol
2. Mouse: to assist Michael with laser
3. Mouse & Ian D: get some parts together for prototyping carbonated drinks dispensing
4. Seb P: produce design for optic delivery device
5. Seb P: continue with carousel!
6. Banjoface: continue work on vaporiser accompaniment to BarBot (which is looking amazing!)

Outstanding Tasks

1. Cocktail Research: Make a list of candidate (doable) cocktails to aim for
2. Prototype squirters
