  • I've created a PI/python3 code example: https://github.com/MarkFiechtner/BigClock

    It is a 4-digit clock with blinking colon for the second. (third digit is upside down!)

    Added a hardware directory to show how I hooked everything up to the PI. I used lots of Sparkfun products -

    SparkFun Logic Level Converter - Bi-Directional (https://www.sparkfun.com/products/12009); SparkFun ATX Power Connector Breakout Kit - 12V/5V (4-pin) (https://www.sparkfun.com/products/15701); (4) 7-Segment Display - 6.5" (Red) (https://www.sparkfun.com/products/8530); (4) SparkFun Large Digit Driver (https://www.sparkfun.com/products/13279); (1) Jumper Wire - 0.1", 6-pin, 6" (https://www.sparkfun.com/products/10371); (2) Jumper Wire - 0.1", 6-pin, 12" (https://www.sparkfun.com/products/10376); Another 6-pin jumper to connect to the first digit from the level converter (4", 6" or 12", depending on your need)


  • I agree with ShapeShifter's comment. I am not an Electrical Engineer nor an Electrical Tech. I don't wire anything that could hurt me or cause a fire (mains level AC) when I mess it up. For my neighbors and me, my connecting a Raspberry PI GPIO (3.3v) and ground pin is a safer alternative to a completely "roll your own" 110v relay solution. YMMV. I currently use a rPI, OctoPI and this to control the power to my 3D printer and an associated light for the status webcam.

No public wish lists :(
