Entry 2 - Previous Eagle CAD Files & Ubuntu

Before getting into the files, I attended a meeting to go over some git stuff for the Unity and AR project for Dr. McColgan's group. Good refresher on git, but still painful... I hope we won't need to use it much for this project.

Parts for circuit b (audio-frequency transmitter):

  • 4 x 2kΩ resistor
  • 1 x 12kΩ resistor
  • 2 x 10kΩ resistor
  • 1 x 1kΩ resistor
  • 3 x 47kΩ resistor
  • 2 x 1nF capacitor      (1nF=100pF)
  • 1 x 100kΩ Potentiometer
    • 1 - V_in
    • 2 - V_out
    • 3 - GND
  • 3 x LF411 Op Amp
    • 1 -  unused
    • 2 -  - (end)
    • 3 -  + (end)
    • 4 - unused    [+ (side)]
    • 5 - unused
    • 6 - out (tip)
    • 7 - unused    [- (side)]
    • 8 - unused
  • 1 relay (HE700)
    • L - 20.14mm
    • W - 7.62mm
    • H - 5.82mm

Parts for circuit c (receiver):

  • 1 x 330kΩ resistor
  • 1 x 330Ω resistor
  • 2 x 15kΩ resistor
  • 1 x 370Ω resistor
  • 1 x 150kΩ resistor
  • 1 x 2kΩ resistor
  • 1 x 1.5kΩ resistor
  • 2 x 10nF capacitor
  • 18nF capacitor 
  • 3 x LT1007 Op Amp
  • 2 x relays

  • "The wires from the arduino connect to solder pads, but the bundle of wires sometimes disconnect. Consider replacing some of the solder pads with headers."
  • Make sure all labels are on the same top layer
  • Capacitors on circuit c don't match footprint on the PCB - check library file
  • Relays do not fit the footprint on PCB - check library file

**so i never actually got this to work, hopefully i'll get it soon.
