Mini 7-Segment Clock V3

While I waited for the Mini 7-Segment Clock v3 PCBs to arrive, I got to work on designing an enclosure. First, I exported the PCB from EAGLE to SketchUp. I then assembled a complete 3D model with all the necessary components. With the 3D model complete, I could then design an enclosure to house the PCB and know exactly what it's going to look like before printing it. I even incorporated a little cable strai ...

Large 7-Segment Clock, Part I

I was extremely satisfied (and proud) of the way that the enclosure turned out for the rework of my 7490 Clock. The electronics on the other hand, is another story. Since it was one of the first things I ever built, I decided to put it in an enclosure of its own and consider it too as a finished product. The problem was that the prototype never ran properly. It worked, just not as well as it should. Needles ...

Arduino 7 Segment LED Display and Counter – Tutorial #8

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push button increment of the counter from 0 to 9. The whole circuit can be powered from a standard 9V PP3/6F22 battery, or from any suitable Arduino power adaptor.The seven segment display is infact a very simple d ...
