Who's doing what
- Michael E: Investigating servo pinch valve
- this will be timed rather than measured so calibration of each valve is required per ingredient
- one valve per ingredient bottle
- Tower Pro SG90 9g Servo - have one for prototyping - DX bulk order - cheap
- laser cut mech
- 6mm soft silicon tubing - check HS consumables -
- find reliable local supplier
- for long lengths we don't need the nice stuff - just cheap plastic tubing is enough - need connectors though. http://www.wilko.com/fish/wilko-aquarium-airline/invt/0121966?VBMST=aquarium
- pets at home (expensive but local)
- Arduino servo control shield and code
- bottle interface
- cork/bung with hole - cheap pourers with silicone sleeve
- bottle is inverted
- bottle needs holder of course.
- Bottle holder: hose clamps/rapstraps, presentation aspects, changeability,
- Michael: investigate peristaltic pumps
- can be as cheap as pinch valves
- very controllable
- https://www.thingiverse.com/tag:peristaltic
- lasercut parts
- continuous rotation servos or steppers - can use single stepper and gearbox
- spills and mess, hygiene and cleanup
I now have 2 types of 6mm tubing: cheap plastic from wilkos and some more expensive silicone tubing from the Range -- Michael Erskine 1 April 2014
I have ordered a cheap 2l bottle fizzy drink tap from a HK ebay seller - these might be a cheap answer for carbonated mixers -- Michael Erskine 1 April 2014
