5×7 LED Dot Matrix Pong
Here’s a LED pong game played right on the breadboard. The LED dot matrix is driven with time multiplexing. The columns are displayed one by one in rapid succession, giving the illusion that they are all lit at the same time. Source code and some photos to get your started. Link.
I was looking for something else, but then found this and figured it might come in handy for something- here’s how to control the parallel port with Perl using a module called Device:ParallelPort. Device::ParallelPort is a Perl API that allows low level access to the parallel port of most computers. It does this by using a number of drivers, which can be customized and added to, including Linux (direct and parport), Win32, Script, Dummy, and more. It also contains a number of direct access devices including an example printer and a relay controller card.
This DNA kit is for kids, but might be fun for all ages (and for some potential projects). It says you can view and map real DNA, do experiments as well as extract DNA from vegetables. It comes with a Centrifuge, mixer, electrophoresis chamber and other parts to perform the tests. Some bad news for Canadians, two of the 10 experiments included in the kit require the “Lambda DNA” which does not ship to Canada.
Mike Sandman has a page of gadgets you can buy that are powered by your phone line. They’re described as Consumer products that get their power from the Phone Company, instead of the Power Company– I’m thinking that I can convert a couple lines here to power some gadgets, outlets are a precious commodity. I couldn’t find any resources for doing anything like that so perhaps I’ll just tap in to it and see the best way to get that 23 to 80ma of power.
Clever! I wonder if this would allowed on a plane. This is a tale of my new daily-use computer. It’s a full-function pc, running Windows XP Pro, with an amd athlon xp 3200+ cpu, 768 mb of ram, 3 monitor ports, plenty of usb ports, and a built in 10/100 switch. And it’s a suitcase. It has a handle. It has two latches. I take it to work with me every day, and take it home every night. All it doesn’t have is a CD Drive. Here is its story. Thanks Chris!

Finally, all those OmniSky, PointCast, COMDEX and piles of other shirts in that bottom drawer can be used to make a huge quilt. I just gave a bunch of shirts, but I think I have enough to make a quilt. And here’s a
