A Flat Panel Display Controller

November 15, 2011 by Chris
“Raster-scan displays, like a TV, require a number of synchronization signals to operate. The display is addressed as multiple, consecutive, horizontal lines, which scan from left to right, displaying a large number of pixels on the line as it advances. At the end of a line, the display begins to scan the next line from left to right until the entire frame (consisting of many lines) is displayed.”

It might seem like overkill and it is, but here's a t-shirt that lets you know how many new e-mails you have waiting in your inbox. The system is designed using the Lilypad 'clothing mod' technology and some off the shelf wireless modules.

The V5Z80P @ Retroleum

September 8, 2010 by Chris
This is a cool little board designed with a Xilinx Spartan FPGA at its heart. It's meant to be a single board computer and I thought everyone would get a kick out of it. The specifications are enough to do some impressive stuff and there's even an archive of great documentation if you wanted to build your own!

PICAxe Serial Keyboard

September 30, 2009 by Chris
The PICAxe serial keyboard was built to interface with a XENIX computer. It is fairly custom when compared to the way keyboards work now-a-days. However, I felt the project was noteworthy enough to take a look at. Hardware schematics & software are available for download.

WMD Case Mod

July 21, 2008 by Chris
Although it doesn't have anything directly to do with electronics, this case mod is just too unique to not take a look at. A case mod specialist had the bright idea of making a terrorist-looking WMD computer case. Read the write-up for a full description & more details.

Minimig – An Amiga in an FPGA

July 3, 2008 by Chris
From the project write-up: "Minimig stands for Mini Amiga. Minimig is an FPGA-based re-implementation of the original Amiga 500 hardware." It's definitely worth a look for anyone interesting in how emulation of hardware & software on FPGA is done.

This is a very helpful little guide for mod'ing an old printer so that you can print to it via WiFi. It's very straight forward with a lot of pictures and helpful tips. The example printer used is an old laser-jet printer.

The “K’nex-ITX”

March 22, 2008 by Chris
You might remember K'nex from your childhood days, it's pretty much like a plastic erector set. This setup is a small case for a little embedded linux box. Honestly I'd imagine it would melt after a few hours of running, but a novel idea in the least.
