BarBot/Dispensing Ingredients

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")
  • 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
• Peristaltic pump
  • Silcone aquarium tubing: http://www.ebay.co.uk/sch/Tubing-Valves/177800/i.html
• Gravity / pinch values
  • Inexpensive TowerPro 90 servos SKU: 188549 x6 £12 to drive value
  • Concerns about consistent flow rate & dripping
• Tippers

Mixers

• Fizzy & non-fizzy
  • Some viscous / sticky may constrain delivery mechanism

Ice

• How to dispense?
• How to keep solid etc.
