  1. The Automatic Keg Tap

  2. Not Good

  3. Our Design

  4. The Pump: Reciprocating Arm Motor

  5. The difficulties of recreating a hand

  6. 1st Hand Prototype

  7. Serious Issues

  8. 2nd Hand Prototype

  9. 3rd Hand Prototype

  10. Adding Circuitry 1: Driving the Motor Max Output Voltage: 5V Desired Input Voltage: 12V

  11. 12V Solution:Transistor Switch 5V

  12. Adding Circuitry 2: Turning Pump on and Off Pressure Sensor (14.5 psi)

  13. Problem 1: Sensor decided to stop working

  14. Problem 2:Found new one, but…

  15. Solution (Unfortunately):Timer and Flip Switch

  16. Circuitry

  17. The Bad • Does not sense pressure • Not very portable • Difficult to attach • A bit shaky • Some noise • Loose nuts and bolts

  18. The Good: • Automatic • Minimal Effort (flip a switch) • Can attach to any keg tap • No cutting or invasive maneuvers required • Way quieter • Cheaper • Good flow
