  • Here’s an Arduino project that uses these large digits with high(er) current sink shift registers: tpic6a596

    The board (that’s made) can be used as a general purpose 1-4 Digit display driver for these large digits!

  • What if we want a greater RFID distance than just a few inches? Would love to build a low(er) cost timing system like the one they use at races; Chips (velcro'ed) on the leg and gets marked/taged when one runs over a mat (rfid antenna?)
    You mentioned 2 tags can cause issues… no mention how how to get around/fix this?
    Thanks for a great video!

No public wish lists :(
