 ======================
 
-+ Peristaltic Liquid Pump (12VDC / 300mA) with Silicone Tubing
-+ 12VDC Adapter (leftover wall adapter) to power the motor
-+ Programmable device to control motor activity:
-+++ [Option 1] Raspberry Pi Model B
-+++ [Option 2] Arduino Uno (Or Similar) 
-+++ [Option 3] Your alternative controller of choice.
-+ Some way of routing power to/driving the motor:
-+++ [Option 1] L293D [ http://www.ti.com/lit/ds/symlink/l293d.pdf ]
-+++ [Option 2: Arduino Only] Seeed Studio Motor Shield (or other shield)
-+++ [Option 3: Raspberry Pi Only] Gertboard 
-+++ [Option 4] Power Transistor
-+ [Optional] Momentary Push Button/Switch for manual fluid delivery
-+ [Optional] Something to house the components (I like OpenBeam or MakerSlide)
