A team at UNC Charlotte has been working on an autonomous vehicle to drag a cart that has sensing equipment. Starting with a stock Honda ATV, different systems were added to give a Renesas processor control of the ATV.  A model airplane receiver was attached to the Renesas to give remote control for Phase 1 of the project. Basically they’ve turned the ATV into a giant remote controlled car.

Later revisions will incorporate LIDAR, cameras, and multiple GPS units so the ATV can autonomously traverse most terrain with a high level of accuracy. Path planning will become a large part of the project at that point.

Turn your Playstation 3 into Linux-based Lab Equipment

filed under: home entertainment hacks, misc hacks

In a two-part series called “PS3 Fab-to-lab” on IBM’s awesome developerWorks website, [Lewin] explains how to use the Cell Broadband Engine in a PS3 to create an audio-bandwidth spectrum analyzer and function generator. The set up consists of Yellow Dog Linux, an NTSC television, and an external USB sound card to provide the inputs of the spectrum analyzer and the outputs of the function generator. The sound card driver is written to simply capture or send the info in question (audio range only) and the NTSC television as the graphical interface. This hack involves a lot of coding with hardly any example code provided. The article is more of a guide than anything. If anyone gets this working, let us know!

MioPocket 2.0 Release 27

Miopocket Screenshot

GpsPasSion forum member [Ospray] has released a new version of MioPocket. For those of you that don’t know, MioPocket is a great unlock kit for GPS units. It basically unlocks the hidden potential of your GPS so you can access the built-in functionality of a PDA as well as retaining the GPS software. This means you can play music, watch video, play games, read and write office documents, and many other things with the once single-purpose device.

Originally written for Mio brand devices, it has been successfully used on a couple other brands. We’ve seen it on a Navigon 2100 using a modified install. This software can run directly off the SD card, so it can easily be updated or removed.

The fun part is fiddling with the scripts to get the newest releases to work on the Navigon and Magellan devices.

DIY kidney machine saves girl

When the tool you need doesn’t exist, you must make one. That’s exactly what [Dr. Malcolm Coulthard] and kidney nurse [Jean Crosier] from Newcastle’s Royal Victoria Infirmary did two years ago.

When a baby too small for the regular dialysis machine (similar to the one pictured above) needed help after her kidneys failed, the kind doctor designed and built a smaller version of the machine in his garage, then used it to save six-pound baby Millie Kelly’s life. Since then the machine has continued to be used in similar emergency situations.

Magnetic stripe card spoofer

After building a USB magnetic stripe reader, [David Cranor] has found a way to fool a magnetic stripe reader using a hand-wound electromagnet and an iPod. The data on a card is read and stored on a computer, then encoded as a WAV file using a C++ program. The iPod plays the WAV file with the data through a single-stage opamp amplifier connected to the headphone jack. The amplifier is used to drive the electromagnet. Video embedded after the jump.

By no means is this a new idea. There have been a lot of magnetic stripe projects and software. This project in particular references the 1992 Phrack article “A Day in the Life of a Flux reversal” by [Count Zero].

Don’t get your hopes up just yet on strolling through high security installations using this little device. It can only replay the data from a card that has been recorded. If you don’t have a known working card, it won’t get you very far.

How-To: Super simple serial terminal

filed under: how-to, peripherals hacks

This hack shows how to make a dumb terminal out of a keyboard, LCD screen, and an 8-bit microcontroller. From time to time, a portable dumb terminal can be handy for when you have to rescue a headless server that’s acting up or if you are building a minicomputer out of a WRT, or if you just want to learn how to run a keyboard and LCD screen with a microcontroller. This super simple serial terminal will use RS-232 to control a headless linux system. Additionally, you might want to check into some of the command line interface programs that allow web browsing, AIM and IRC chatting and more directly from the terminal, but nothing beats being able to track your pizzas with this device.

The Linux system in question here will be Linux Mint. It’s a young distro based on Ubuntu that’s gaining a lot of attention lately, though the principles can be used for other Linux distros.

The guys at I-hacked put up a how-to on giving your windows mobile phone some iPhone skinned powers, but later in the day they decided to make it login required. Thanks to [Katrina] for the tip. (requiring logins for contributed content just doesn’t sit well with me.)

[chris] sent in his own round up of his personal projects.

[Chris Coleman] let me know about hacktherazr. They’ve got some decent guides on customizing just about everything on the things.

[Ben Heck] got sick of emails, so he’s offering to build one more xbox 360 laptop, if you give him a pile of money.

Staring sunday, I’ll be ripping the hell out of my new house (and re-doing most of the upstairs). Do me a favor and keep the tips line brimming over.

[David] has some interesting ideas involving wireless AP antennas and wireless keyboards. How about a cantenna…

Hack a Day serves up fresh hacks each day, every day from around the web and a special How-To hack each week.
