PSP firmware 5.03 has been hacked by Team Typhoon. This allows you to run custom code on the PSP by taking advantage of the tiff exploit. You’ll have to wait to download the hack though, they haven’t released it yet. This means those of you still on 5.02 or still using the little blue tool will be able to upgrade soon.
[Daniel] had to have runaway in his mind when he built this coil gun. It’s hand held, holds 14 42 gram rounds and can propel them at speeds of 110km/h. Of course when it is battery powered, you have a 90 second warm up time between shots. It can also be used while plugged into a wall socket, which reduces the charge time to roughly 3 seconds. Great job [Daniel].

[Windell] from Evil Mad Scientist Laboratories took one of their Peggy 2 kits and gave it a little upgrade. The Peggy 2 is a programmable 25×25 LED display. It’s Arduino compatible and can accommodate big 10mm LEDs. Most people assemble them using just one color, but [Windell] decided to create giant RGB pixels by placing discrete red, green, blue, and white LEDs next to each other in the board. This creates a 12.5×12.5 grid of full color pixels. It’s an interesting effect and you should definitely check out the video embedded below which shows how the transition can be smoothed using a diffuser. Continue reading “Peggy 2 Super Pixels”

Here’s a pretty cool project done with the Lego NXT system. It’s a robot that will draw you a picture. Yes, we know it could be done cnc style, but this is much more fun. You load a picture into the software, adjust the levels so the software can create the vector version more easily, then let it rip. Now they need to add face recognition.

[TokyoDrift] has added mouse support to his PSP. He’s using a microcontroller to interpret for the PSP, through the serial port. You can see in the video above that this provides a functional mouse control, especially useful for first person shooter style games. He’s got lots of details as well as schematics available in the forum posts. We’ve seen other controllers added to the PSP, but this is the first time we’ve seen a mouse.

[Jonathan] sent us his final project for ECE 476. His group built an LED POV display that can be updated wirelessly from a computer. They built it in a somewhat modular fashion, with the LED strip being a simple to replace module. This goes along with their plan to build a 3D version of the display. They have made it able to switch easily from it’s internal programming to direct computer control, allowing them to leave it alone in clock mode, or take control to play with it. The updates seem really quick, you can see them in effect in the video after the break. All source code and schematics are available on the site. We love these final projects, they usually have tons of data and great pictures. Keep them coming.
It’s been many months since the T-Mobile G1 was initially rooted. In that time, the process has been streamlined and tools have been built to make it much easier. Having a rooted phone has become even more desirable with the recent release of the 1.5 firmware that includes an onscreen keyboard along with other improvements. Having a rooted phone means you can do tricks like setting up a 3G/WiFi bridge. [Taylor Wimberly] has written a guide to help you easily root your G1 without having to go digging through forums for software bits. The process starts by using [Mike Moussa]’s rooting app to revert the phone to the RC29 build. You then use the “Android stupidly executes everything you type” exploit to launch telnetd and upgrade the bootloader. After that, the upgrade process is fairly easy. You just flash a new baseband and build. Once you’ve got your new custom firmware, you can do future updates using an app from the Android Market. We recently updated our Android Dev Phone 1 to 1.5 and haven’t had any issues.
