Raspberry Pi LED display board
Jeroen Domburg, known online as "Sprite," was given a very interesting piece of hardware to bring back to life: a dual-color 224x48 LED display board that had previously been used to display information for some kind of transportation system. In a rare occurrence, he was also given all the necessary power supplies and the industrial computer to drive it.
Right in the middle of Jeroen's project documentation you'll get a glimpse into the art of computer hacking. The computer boots up, gives him the hardware specs, then goes to a blank screen. His task was to find out how to get access to this computer and gain full control over the network in a few minutes using publicly available tools.
Once he had the display working like it was originally intended, he had to take it a step further. This is where the Raspberry Pi comes in. With its power, network access, and gpio pins, it was a perfect fit to drive the display. Jeroen loaded a linux distrubution and video client on the board and got the results you see above. Note that the flickering is due to the refresh rate of the screen and the refresh rate of the camera overlapping -- it doesn't have this issue with the naked eye.
Thanks for sharing these cool projects. Coming off of our hugely popular Raspberry Pi hands on workshops at DESIGN West 2014, we're already organizing our sessions for next year. These projects inspire me to think outside of the box on what we can provide for attendees to build.
Some nice little tutorials on these pages. The word is books are being written as teaching material on the Raspberry Pi as platform for a variety of subjects, so hopefully we're poised to see it take off in computer science classes.
This is really cool. I am very impressed by all of these projects. It's wonderful to see that people are doing such innovative and creative things with Raspberry Pi. I especially love the retro phones stereo control, the Atari emulator and, of course, the R2D2 (who doesn't?)
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
