My Nerdkit LED Array Continued…

This was the second post for my array.  In this one, I show the cabinet I built to house it.

In case anyone is still interested, as I said I would do, here is the followup to my marquee project.

After a couple of hours of playing with the table saw, router, and brad nailer, the marquee is looking a bit more finished.  I built a nice little cabinet for my marque from some pine lumber I had.  Add a bit of stain and a NerdKit and voilla, its finished. (except for making a back) 🙂


Here’s a view of the back.  I plan to add a thin back and possibly make a more permanant (NerdKit) to stay in the box.

Now I just have to figure out how to make a phrase scroll without sending it via serial.

I made a quick video and posted it on YouTube.  Pardon the mess in my computer room!

This is the most recent full program I have. All the text that is displayed is in the function do_testpattern(). You’ll notice the last time I used it was to wish my wife (Donna) a happy birthday… 😀 Anyway, the main function calls do_testpattern() and the while(1) loop keeps it there indefinitely. If you have any other questions please ask. This program was my first major modification and my 1st full learning experiance with C. So there may be some programming methods used that aren’t quite right, but it works…


Fun times ahead.

    It seems as if nerd kits has gone out of business and I wanted to build one of these led projects, any suggestions ?

      I have my complete build step by step here on my blog. I also have a link to the software I updated to add some extra affects. What questions do you have exactly? I don’t have their guide as I never purchased one of their kits. Plus, from what I understand, their kit was not really much anyway. Do you have a “NerdKit” microcontroller kit? If so, all you need for the array, as they build it, are 120 LED’s, some wire, a piece of cardboard, basic soldering skills, and a lot of patience.
