Dispensing Ingredients
Getting the right quantity of each ingredient into a glass/shaker/whatever.
Spirits
Spirits are the main event here. Whisky, Vodka etc. In the UK single measures of spirits are either 25ml or 35ml at the discretion of landlords (35ml traditionally being used in Scotland according to wikipedia). We need to be able to dispense fairly precise measures. If commercialised, dispensing volume needs to be stamped by a government agency who test the device.
Methods
- Optics, also knows as "optic pearls" (Daniel, Mouse to do prototypes)
- 25ml/35ml Beaumont style optics look nice. Cheapest price for delivery of one was £12, larger numbers are cheaper
- Other styles may or may not be easier to mechanise
- Pinch values / gravity pinch values
- Concerns about consistent flow rate & dripping
- Peristaltic pump (Michel E to prototype)
- Tippers (any takers?)
Supplies
- Silcone aquarium tubing for making p. pumps
- Inexpensive TowerPro 90 servos SKU: 188549 x6 £12 to drive value
Mixers
- Fizzy & non-fizzy
- Some viscous / sticky may constrain delivery mechanism
Methods
- Fizz drink dispenser
- Postmix system (TODO: find out prices / if affordable)
Ice
- How to dispense?
- How to keep solid etc.
