Number Crunching

Today we spent most of the day cost comparing the peggy board against building our own "peggy" board and doing a evaluation to see which would be the most economical for us.

Buying the Peggy Board
Peggy Board: $95.00
LEDS (625count) : $131.00
D Cell Batteries: $7.00
FTDICable: $17.00
Sensor: $15.00
Total Cost: $265.00

Builidng our Own
Arudino: $34.99
Mux Shield: $25.00
Sensor: $15.00
LEDS (200): $63.60
Transistors: $12.35
Board: $10.00
Total Cost: $160.94

Building our own but smaller (if we use the capacity of the arduino, we will save $25 on not buying a mux shield, save money on the amount of leds , and on the amount of transistors we need)

Arudino: $34.99
Sensor: $15.00
LEDs (60): $45.60
Transistors(7):$6.65
Board: $10.00
Total Cost: $105.59
