computer hacks
HD-DVD drives are getting closer, but aren’t terribly easy to come buy – yet. [Dan] over at uneasy silence let us know that he cracked open an XBox 360 HD DVD Drive and plugged it into a windows box and a mac. With a light application of some drivers, they got the drive working pretty easily – the snag? You’ll need a mini-ata adapter if you want to mount it internally. (And there’s apparently no HD-DVD software support for mac… yet.)
[you can just use it as a USB drive.]
Ben Heck and I got into converting a mill to be a CNC machine during our podcast interview. Today I found a pair of great write ups at balbots on modding the Harbor Freight mini mill that I mentioned. Part 1 get into all the details of converting the mill to use stepper motors, and adding a cooling system. Part 2 covers upgrading to DC servo motors and replacing the gears with a belt drive system.
I’d call this more of a video mixer with audio inputs, but it’s an interesting way to hack video signals. [brian] sent in the VS001 Analogue Video Mixer. He noted that it’s along the same idea as the Mac SE/30 visualizer, but outputs VGA and can route signal through audio gear for even more interesting permutations. It looks like all the information is there if you want to build your own.
[Alan] sent me his simple rs-232 controlled power outlet. He built it to turn on his laser printer when a print job appeares in the queue. The relay is directly controlled by the DTR line on the serial port. Lots of espresso machine PID conversions use them to run boilers, so he could have avoided the extra mechanical relay. [I can’t pick on him too much, my old laserwriter is on all the time.]
He tied it together with some perl to turn on the printer and get the print job going once it’s had enough time to initialize.
[Jared] sent in inventgeek.com’s ion cooler 2.0. This time the ion cooler is pushing air out of the case to avoid charged air crossing the sensitive components. They kept the cost down and used easily acquired components.
[Ethan] sent in the online skill crane. It made it to shmoocon, but now it’s online for anyone to play. The machine is interfaced to the parallel port and controlled with a C program. It lacks a bit on the tech details, but you know you want one. Playing nets you a video of the results linked via email.

We’ve got plenty of tricks around here, and I’ve got a treat coming up – you’ll hear about it in the next podcast.
[Ronald Schaten] sent me his USB LED fader. ATMega, PWM lit LEDs, he uses it to indicate status on his pvr.
[computerguru365] sent in his cell phone car charger turned USB cable
[steve] sent in this over the top C64DTV mod.
[Everett] sent along his button activated PSP shoulder lighting.Nice tiny soldering work for that on.
[Jorge] sent in his friends latest junk art metal lathe. Not an easy thing to build – Nice!
[gijs] sent me this crazy bent Casio SK-1. We’ve had a few of these on Hackaday before.
[seniorcheez] sent in his iPod shuffle dock with integrated power and tunecast.
