Check out this visual hardware guide from deviantART member [Sonic840]. It has everything from memory modules, to bus sockets, to power connectors, to an entire array of CPU sockets that have been used over the years. You’re bound to see something in there you didn’t know existed.

TechEBlog has posted a few pictures of a student constructed coil gun. It’s bolt-action and includes a six round magazine. The gun only has a single stage to accelerate the projectile. While not as impressive as the portable coil pistol, it’s still more fun than most shop projects we’ve seen. You can find a video of the device below.

A friend recently commissioned us to install OSX on a netbook. We advised him to purchase the Dell Vostro A90. It’s essentially a rebadged Dell Mini 9, a model that has been discontinued, but is well suited for OSX. It’s only available with a 1.6GHz Atom processor, 1GB RAM, and 16GB SSD. Depending on what deals are available, it’s $250-$300. We also had him purchase a 2GB stick of RAM which is the upper limit supported by the BIOS.

Having read Gizmodo’s guide earlier, we knew that process would not be too difficult. The install has actually gotten even easier in the last few months. We followed the DellEFI guide hosted on mechdrew without many problems. The only equipment we needed was a retail Leopard disk, a Mac, and our trusty USB/SATA adapter attached to an old 120GB laptop drive. We copied our image of a legitimate 10.5.6 retail disk to the harddrive and then used DellEFIBootMaker to make it bootable. We copied the DellEFI 1.2a5 program and the 10.5.7 cumulative update to the drive as well. With this, the drive had everything we needed to complete the install.

Plugging the drive into the Vostro A90 we dropped into the BIOS setup to turn on USB legacy support so we could boot the drive. We found that we’d often have to go to BIOS first, then exit in order to give the drive time to spin up and appear in the boot menu. After partitioning the laptop drive, the installation is identical to any other Leopard install. The process froze on us on two separate occasions before we got a complete install. It was just a matter of try, try again to get it to work. We think it may have been the fault of the drive we were using. After that completed, we were able to boot our brand new OSX machine and install the 10.5.7 update. We used DellEFI to install the permanent bootloader.

Everything seems to work fine and it’s a lovely little machine. We highly recommend the DellEFI single USB drive method which was Version 3.02 at time of writing.

In the video above, [conquerearth] is using a theremin to control Super Mario Bros. Moving his hand toward and away from the vertical antenna increases the theremin’s pitch. The computer monitors this in real time and moves Mario left and right. The loop antenna controls the theremin’s volume and acts as the jump button. The controls seem to work well, much better than the sound of one man flailing at a theremin.

The Irregular Incurve is a robotic instrument built by [Xiaoyang Feng] as part of his ITP thesis work. It’s a MIDI instrument with an array of 12 strung bows mounted to a curved shower rod. The end of each bow has a tuning key. The strings are each picked using independently mounted arms. One servo controls the downward motion of the pick while the other controls the rotation of the shaft. A damper is also attached to each arm. The string vibrations are transferred to a spruce soundbox under the bridge. Below you can see a video of Gizmodo playing with it at the ITP show. Check out [Xiaoyang]‘s Flickr set for images of the build process plus some early videos of the mechanism.

Installing OSX on commodity PC hardware has advanced a lot since the early days of OSx86 when Apple switched to Intel. With the advent of netbooks, a new target platform has emerged; one that doesn’t have an official Apple equivalent. The small subset of models means that it’s easy to find someone else that has the same machine as you, but it still takes some forum walking to bring all the pieces together. Gizmodo has done this and compiled a comprehensive guide for the Dell Mini 9. The Mini 9 is a very nice machine and according to Boing Boing Gadgets’ chart, one of the most compatible with OSX. Earlier this week you could purchase a new one for just $200.

For Gizmodo’s install, they used a Leopard retail DVD with [Type11]‘s bootloader. They’re breaking the EULA, but at least it’s not piracy. They had to use both a DVD drive and a USB hard drive because device recognition was flakey. Despite this, the actual install process doesn’t appear to be too difficult. They say all the hardware works, “The Mini 9 is a beautiful OS X machine.” Check out this Hackit to learn about netbook OSX experiences from other Hack a Day readers.

Gizmodo has done us all a favor by wading through many forum posts and condensing them into a handy guide to installing Ubuntu on your Playstation 3. It covers some of the caveats of going this route. You have to backup all of your game data before starting since the system repartitions the drive. Ubuntu installs without any problem, but because the cell processor is a PowerPC architecture it means not everything has been ported to it. There are a few things you need to install to get the Sixaxis controller to be recognized as a joystick. Super Nintendo emulator SNES9X is available and works, mostly. It doesn’t support fullscreen and cries if you reconfigure the buttons.

Supporting developers through alternate operating systems isn’t new to Sony. With the original Playstation, they released Net Yaroze, a consumer grade dev kit. The Playstation 2 was the first time they officially supported Linux on a game console (our first Linux machine). The ground breaking thing about the Playstation 3 was bundling in Linux support with every single console; no specialized hardware needed. Unfortunately they’re not near as open with the PSP.

The last time we checked in on Pandora it was just being shown in dev unit form. Embedded above is a video of the first case prototype. It doesn’t have any components yet, but it definitely looks like a good formfactor with a lot of potential. The Pandora is a Linux based portable game console with an 800×480 touchscreen.

Here’s another bizarre keyboard mod to add to the pile. Unlike previous typewriter style mods, this one uses Scrabble tiles. All of the tiles were hand beveled and attached to a clicky keyboard. The Num, Cap, and Scroll lock buttons have their letters’ hollowed out so the LED light will shine through.

Have you ever wondered how they inspect high voltage cables without taking them out of service? Check out this video which offers a glimpse into the life of a professional high voltage cable inspector. There are parts of the job you’d expect—namely perching on the cable like a bird, trying to not fall off—but the part of the job you wouldn’t expect is the suit. This suit is made of 75% Nomex, to prevent it from catching fire, and 25% stainless steel thread, turning the suit into a wearable Faraday cage. Of course, because he’s got a Faraday cage mere millimeters from his skin, the cable inspector spends his workday surrounded by half a million volts.  To avoid electric shock, he equalizes the voltage potential between himself and the line before touching the cable.

Depending on your specific phobias, this video might make your job seem really dull… or really really safe.

Hackers are continuing to outpace Apple with feature additions. The team at iMobileCinema has created a flash plugin for the Mobile Safari browser. It’s a beta release and still a bit buggy. This app is only available to people who have jailbroken their iPhones. You just need to add d.imobilecinema.com to your sources in Cydia to get the package to appear. While it can crash from time to time, it’s certainly better than no support at all.

Embedded above is [egyokeo]‘s solution for using MIDI drums with Guitar Hero. He’s playing a DrumKAT MIDI kit. It connects to a PC running his MIDI Hero software, which handles timing and multinote combinations. The PC uses a USB ToolStick microcontroller to send commands to the console using an FPS adapter or soldered into the instrument. It’s a fairly good solution if you’re building a generic controller and need to modify the signaling.

When Rock Band was first released, modders sought to adapt their MIDI drum kits for use with the game. The easiest solution they found was Highly Liquid’s MSA-P. It’s a photorelay based MIDI decoder. You need to solder directly to the brain in the Rock Band drums. If you’re planning on modding any instrument, check the compatibility matrix first. Hopefully you’ll end up with something that can be used across multiple games.

In case you were wondering what industrious hacker [Joe Grand] was doing when he’s not building stuff for Prototype This!, designing Defcon badges, or testifying before congress, it’s this: The BSoDomizer is a VGA pass through device that displays an image of your choice on the victim’s screen. It can do this either periodically or via an IR trigger. The image of choice is a Windows style Blue Screen of Death. It’s powered by a watch battery. The project site has all the schematics you need plus ASCII goatse imagery; you’ve been warned. Embedded below is a demo of the device. We unfortunately didn’t get to see it when it was originally presented during Defcon 16.

Yesterday, Gizmodo published a roundup of wearable gadgets for people who “don’t mind looking like a tool”. It’s interesting to see what has been deemed commercially viable and put into mass production. The list covers HMDs, embedded WiFi detectors, integrated keyboards, tech jackets, speaker hats, and others. We thought you might find some inspiration from the list for your next project. In the past, we embedded a WiFi detector in a backpack strap for our Engadget how-to. The natural choice for wearable projects is the LilyPad Arduino which was featured most recently in the turn signal jacket.

We remember the halcyon days of firmware 1.00 for the PSP. It was wide open to run any code you wanted. Once the handheld game console was released outside Japan, Sony locked it down and began an arms race to prevent any sort of homebrew usage of the device. Nearly four years later and we’re at firmware 5.00. The hackers are on top of their game though. It’s only been a couple days since the official release and a custom firmware has already been published. Sony has traditionally supported development on their home consoles and we hope they’ll take that approach on their next portable instead of this stupid back and forth.
