Regrets: Seb P

Agenda: Project status & progress, design talk, hacking things

Summary

• Ian showed automation for plunger with car window winding mech as motion generator!
• Michael on phone described status of carbonated drinks dispenser
  • One lid made
  • Awaiting pressure test (ready, just need time to do it)
  • Awaiting components delivery
• Ed showed an automatic soap dispenser unit from sainsburys
  • £5 on sale, £9 is what Ed paid
  • Cannibalize to dispense small quantities of lemon/lime/tobasco etc?
• Mouse talked about interaction with EMF organisers
  • They're totally cool with us doing our thing
  • There will be another barbot there!
  • They might even be able to help us with buying booze!
• Mouse described what Seb said on Monday
  • We discusses the carousel, motor sizing
• AGM is next week, so maybe just a quick meeting after AGM

Hacking

• Ed hacking soap dispenser
  • needs a head of pressure to dispense non-viscous fluids, but not viscous ones
  • can mechanism switches wires which can be used to control motor (should be simple for arduino)
• Ian helping Mouse with stepper motor control for testing carousel turning mech
  • Stepper and controller from reprap seemed to have enough power to turn it
  • Mock up probably wasn't heavy enough, but it might just work!
  • Slipping of motor on mock wheel was a problem but with a belt drive that should be alleviated

Action Items

1. Mouse: meeting write-up
2. Mouse: to succeed to laser-cut peristaltic pump parts (deferred)
3. Seb P: produce design for optic delivery device
4. Seb P: continue with carousel!
5. Michael E: pressure test of carbonated drinks dispenser

Outstanding Tasks

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

Next Steps

• Next meeting: next Thursday (2014-05-15)
