I’ll tell you what. Fill a city with these things, and I’ll move there. I can’t think of a greater source of childish delight than a playground full of these things, haphazardly zipping around the asphalt, attracting the attention of every bird, dog, and blogger that passes by.

Apple’s charges of copyright infringement and DMCA violation against Psystar have stuck and, friends, things ain’t pretty for the two brothers in Miami. The problem with Psystar’s approach wasn’t that they were crazy for trying it. It’s that the were selling a counterfeit unit.

Apple contends that Psystar has violated its distribution right by offering and selling Mac OS X on Psystar computers to the public. Psystar admits that it has distributed Mac OS X (Chung Exh. 17 at 4).

But Psystar responds that its conduct is protected by the Section 109 first-sale doctrine. Section 109 provides that “the owner of a particular copy or phonorecord lawfully made under this title, or any person authorized by such owner, is entitled, without the authority of the copyright owner, to sell or otherwise dispose of the possession of that copy or phonorecord.” 17 U.S.C. 109. This provision is a limitation on the distribution right. It applies only to an owner of a copy.

Watching this video, it doesn’t seem very much more than a demo for a rather anonymous-looking little touchscreen device, a PMP prototype maybe. Then you find out that the whole thing is running an 8-bit processor with 4KB of RAM. Touchscreen tricks like scrolling momentum are implemented perfectly well, and there appears to be little or no lag. Pac-Man runs at 60fps, which is more than I can say for the version on my G1.

Apparently Monday is DIY day here at CrunchGear, as we have another project for you. Battery powered USB chargers are nothing new — but building one yourself, that’s something different. Using a few components from your local electronics store and a 9v battery, you too can solder together your own little frankencharger.

It’s amusing to me how sometimes how I’ll be considering a particular subject and then randomly find a DIY project related to that subject. For example, I’m been considering getting a medium format film camera, just for the experience of shooting in that format. Apparently I’m not the only one, because Peter J at the Medium Format Camera Project has been building his very own camera.

I’m a sucker for clever desks and organization objects. Sometimes you don’t need a massive Pottery Barn desk to email your parents pics of the kids. All you need is a place to sit and two little shelves from Ikea. (and some handyman skills)

This fun little DIY device is labeled as a “crystal radio circuit in a jam-jar.” But that description doesn’t even to begin to do it justice. According to Tesla, this electronic wonder allows you to hear the disembodied, ethereal voices, of the, well, ether, I guess.

Tired of the hoodlums destroying your pumpkins? Looking for a little payback? Here’s a project that will allow you to get some vengeance. Plus, it’d be fun to shoot silly string at the older kids that show up on your front step this Halloween.

I know, I know. Water rocket. Whatever, right? Been there, done that, it’s cool and all, but it’s kinda like the diet coke & mentos thing. It’s been done to death. Well, this ain’t your daddy’s water rocket, let’s put it that way.

Jeezum crow! This guy has made a fully functional (kind of) Proton Pack from Ghostbusters including a trap, ecto goggles, and some coveralls. He added a few lights controlled by an Arduino board.

The best part? He added lasers to the blasters. Now he just needs to remember not to cross the beams and that your halloween party can be a promotional expense so you should invite clients instead of friends.

One CD-ROM drive: $18.99
Some wire and electrical tape: $2.50
Installing a CD-ROM drive to use as a CD player in your car: priceless.

Well how do you like that? An old Sega SC-3000H from 1983 has been given new life as a fancy keyboard PC. An enterprising modder named Cuzza over in the TechPowerUp forums laid out $4 for the old-timey computer, rolled up his sleeves, and got to work.

So let’s say you need a new clock. Sure, you could go spend $19.99 (or less) and just go buy one, but wouldn’t it be more fun to bust out the CNC machine and build one yourself? Alan Parekh of Hacked Gadgets thought it would be, and he just happened to have a new CNC machine lying around.
