Boot Camp… I Give Up

UPDATE: I’ve solved my issues click the “Continue reading” link.

I’m sure you saw the news of Apple releasing the Windows bootloader Boot Camp yesterday. My current desktop machine is a Core Duo Mac mini so I figured I’d give it a shot (so I could run four folding threads, naturally). I downloaded the Boot Camp package and upgraded the mini’s firmware. The first thing the Boot Camp install assistant does is burn a driver disc for use after the XP install is complete. Once this is done it shrinks the HFS+ partition and creates an empty partition for Windows. It then asks you to insert the XP install disk (must have SP2). The Windows install proceeded normally and Windows booted. This is where my trouble began: the drivers didn’t apply cleanly. I could have retried but for one serious problem. To get the initial boot device selection screen to appear you have to hold down the “alt” key while the machine is starting. The only USB keyboard I have is a Gyration wireless one. The boot menu only showed up at best 1 in 10 attempts. Apple does provide software to choose which OS you want to boot by default, but since the Windows drivers didn’t install there was no guarantee I could flip the switch back to OS X once I was in XP. I decided the flaky “alt” key detection was probably my wireless keyboard not being fully initialized, so I made a late night run to the Megalomart to buy the cheapest wired USB keyboard they had. I plugged it in and tried to bring up the boot menu; it didn’t work a single time. So, my experiment is over for now since I don’t want to get trapped in XP. Hopefully they fix this public beta so that is has an actual boot menu, with a countdown, like every other bootloader. UNEASYsilence has a video of how this install should go.

Mini-SD And RS-232 Board For Zipit Wireless Messenger

zip it add on

Tom Walsh has been hard at work building an add on board for the Zipit Wireless Messenger “IM Device for Teens”. The board adds a mini-SD card slot, RS-232 (using a mini-USB connector) and a power supply for an EL backlight. I’m impressed that he got everything to fit inside of the case, very slick. A year ago we covered putting Linux on these devices. Have any of you readers picked up one and what fun tricks can it do? I looked around and they still cost over $90. I should probably just resurrect my Zaurus and be happy

The Walking Box

[Ryan Walker] had recently constructed a 16 R/C servo controller board and needed a platform to test it with. He wired 6 cheap TS-53 servos from Tower Hobbies to the bottom of an empty box. He’s got push buttons on the top for direction control. It uses a PIC18F452 for processing and the board was routed on an LPKF circuit board mill. There are videos on his site, but try using these cached links first: walking on a table and walking on carpet.

Brain Assailant

Ugh, I didn’t expect this “sonic nuisance” meme to last past yesterday, but here we are with a different project from [jay]. ThinkGeek sells a device called the Mind Molester that emits a chirp every three minutes making it hard to find but frequent enough to drive you insane. Jay figures ThinkGeek’s markup was somewhere around 1250% and decided to build his own. The device uses a Picaxe microcontroller and emits four different sounds a random intervals.

Sonic Grenade

imakeprojects.com started recently with the promise of delivering one project every two weeks. Yesterday was their second release: sonic grenades! They picked up a couple 110dB personal alarms at the Dollar Store and modified them. Now instead of going off immediately, there is a 5 second “fuse” indicated by a flashing LED; giving you plenty of time to lob it into your roommates space. After a minute of being active, the grenade will start chirping every 10 seconds until you replace the pin which should help you find it. There’s a video demo at the bottom of the page.

Hack A Day Goes Autonomous

cuborg

After declaring our independence last fall, complete site autonomy seemed like the next logical step. Using some clever coding we have developed a system that will let Hack a Day run without any intervention. The first layer in this system is topic selection. All tip line submissions are sent through a series of filters. These look for keywords like “firmware”, “POV”, “microcontroller”, “video”, “linux”, “WRT”, “GPS”, “PCB”, “TLA”. Each submission is given a l33tness ranking based on these words and the best tip is immediately thrown away. The second highest link is then passed through our advanced anti-duping engine that confirms the link hasn’t been posted in the last week. The post text is generated using Markov chains in what top scientists suspect is a miracle. The story is then automatically cut and pasted into Digg without credit. To foster discussion the reader comments are automatically seeded with “first post” and “this is not a hack” on every post. This system is implemented using a large quantity of duct tape (code and literal) on our brand new Linksys WRT54G beowulf cluster. We hope this system serves you well. We’ve been working on an “auto-hacking robot” to generate how-tos as well, but on its test run it instinctively disassembled itself.

Reversing Extension Tube For Macro Photography

extension tube

Reversing the lens orientation is common practice in macro photography. To get even more magnification you can increase the distance between the film and lens by using an extension tube or bellows. [Kevin] built this variable length extension tube by modifying a bunch of cheap used filters. When I say “modify” I mean he “broke the glass out with a hammer”. The base of the extension tube is a body cap that has had the center removed. Glued on top of body cap is a filter ring with the male threads pointing forward to act as the reverse lens mount. You can add any number of additional rings to change the length. It’s very important to be thorough when cleaning your filter rings otherwise you might damage your camera internals.
