Compaq Motherboard Power Mod

Some companies insist on using proprietary pieces. It can be really frustrating when there is no apparent reason other than consumer lock in. It irritates us to feel like we’re being forced to buy their pieces. This is one of the more popular reasons listed when you ask a hacker or modder what got them started. This project takes us through making a normal power supply work with the compaq proprietary 14 pin plug found in some smaller desktop PCs.

Aside from the plug itself being different, the motherboards require a 3.3v standby voltage. A normal power supply usually only has a 5v. Though there are even simpler ways of bypassing the issue, he chose to put an inline voltage regulator. Schematics are available on the site.

Apple Adjustable Keyboard USB Hack

When [Tom] got tired of the large size of his Microsoft Comfort Curve 2000 keyboard, he decided to hack a recently acquired Apple Adjustable Keyboard for use with Windows. After removing the ancient ADB based control board from the Apple keyboard, he was able to map the keys and transplant the Microsoft keyboard’s USB control board into the Apple keyboard. After soldering the control board into the keyboard with old IDE cables, all that was left was to add some diodes to prevent ghost key presses, and the keyboard hack was complete. [Tom] offers a spreadsheet of the results of his key mapping on his site, and while you’re there be sure to check out his other projects, like his DIY Proton Pack that he made for Halloween last year.

Intel 8008 Clock

July 7, 2009 by Gerrit Coetzee 11 Comments

Every year [Len Bales] designs and builds a new clock. His 2006 clock runs on the classic Intel 8008 microprocessor. The design is definitely not for the faint of heart, but he includes all code, diagrams and a good description on his site. The project is an interesting look into the not-so-distant past of computing. While the function of the project is a clock, it is actually a fully programmable 8008 computer running at 500khz with 16k of memory space and 4io ports. [Len] also links a lot of useful 8008 resources for anyone wanting to tackle a project of their own.

[Maarten] told us about a C64 USB keyboard that was modified to be used as a standard input device. An interesting aspect of the project is the use of V-USB (formerly known as AVR-USB). V-USB is a software only approach to slow speed USB HID. In essence this is a two fold mod, The C64 keyboard is patched to a PC, and an off the shelf AVR is software-hacked to bit bang the USB communications. The author notes an initial problem with multiple key presses that was later corrected in the application. For the other side of the spectrum, we had covered the C64 twittering client, and a commodore 64 laptop.

[Matt Cutts], head developer for google’s anti spam team, describes how to attach a Wii balance board to a linux computer. He even shows how to make a GUI to show the input. The entire project is done in about 200 lines of python.The process assumes that you can already make a bluetooth connection to a WiiMote, but if you can’t, he’s got instructions for that too.

VR Game Gun

Many of you have probably experimented with alternative gaming interfaces. Here’s a well done little hack where they created a gun with a display mounted on it, for video gaming. At a glance you can probably figure out exactly what they’ve done. They’ve attached a gyration mouse to the gun for tracking and gutted a keyboard for the buttons. We have to give them some credit, they seem to have packaged it all nicely. Since it’s a standard mouse and keyboard, it just plugs in and works with any game. As you can see in their version, the screen works very well in this configuration, almost seeming like a giant scope. You can see the wireless version and hear their aspirations for projector based models after the break.

Dell Vostro A90 Hackintosh

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. Continue reading “Dell Vostro A90 Hackintosh” →
