While the rest of the world is preparing for super sportsing, I’m taking the opportunity to tinker. This post is a continuation of the GaSiProMo challenge I took part in a while ago.
Today’s update brings in the next stage of that project with my OsRAM LED display: better packaging.
The goal here is to reduce the amount of “rat’s nest” wiring from the prototype to a more manageable amount of cabling for better display of the pretty blinky lights.
So I harvested an old Shuttle micro PC for its hard drive cables, which are nicely bundled. The first step was to make a breadboard carrier for the OsRAM.

I chose sockets for wire-wrapping. I’m a big fan of wire wrap. It’s old school, but very rapid for prototyping.


Next up was to make a mapping of the pins from my Arduino to a breadboard. This took a while to derive the most optimal routing of wires.

No to my surprise, the HDD housing has one pin blocked. So I had to Dremel this out.

I have a serial port terminal working so that I can type in any message from the PC and have it show up on the OsRAM:
