The HackLab Bandwidth Display displays our current bandwidth usage on two 4 digit 7-segment displays.
Project Status
- 2013-06-28: Doh, thought this had been submitted but missed it. Submitted to OSH Park w/ express shipping.
- 2013-06-01: Decided that building all the digit boards on perfboard was going to be too much of a pain, designed/schematicized/laid out a dedicated control board for each digit, takes +5, +12, and I2C, and controls the digit. Will get 8 of these made to drive all the digits. Next step is reviewing the schematic/layout tomorrow before sending off to OSH Park.
- 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. Tried to add the anode control, blew up the Arduino putting +12V into an I/O line. Next step is to redo the anode control stuff on the first digit and complete full testing of that before building the other 7 digit boards.
