The HackLab Bandwidth Display displays our current bandwidth usage on two 4 digit 7-segment displays.

Project Status

  • 2013-05-11: Built up shift register/transistors for cathode drives on a proto shield, mostly working. Built up most of the first digit except for the anode control transistor, also working. Next step is to finish the anode control stuff on the first digit and complete full testing of that before building the other 7 digit boards.

  • Arduino Uno
  • Arduino Ethernet Shield
  • Proto Shield w/ 74LS164 + connectors
