Here is the current list of parts needed for the clock. Once I am finished, I will add exact quantites for components like transistors and resistors.

Parts List

  1. PIC16F870(microchip.com) $1.80
  2. 0.01 uF Capacitors $0.19
  3. 2x 5uF Capacitors $0.25
  4. 555 Timer = $0.29
  5. 2x Dual 7-seg display @ $0.75 = $1.50
  6. Normally Open Button $0.99
  7. USB A Connector $0.99
  8. MC14514 4-16 Decoder $0.50
