The guys over at Zedomax.com designed an airplane joystick that responds like the ps3s six axis joystick. The project is not to useful being in a plane, but the concept can be used in various projects. Read the complete workup at Zedomax.com

The GP2X is an open-source, Linux-based handheld video game console and media player. The device is created and sold by GamePark Holdings of South Korea. The thing that makes this gaming console cool is that the company is trying to do things that the PSP(Very limited portable gaming device, sold by a greedy company named Sony) wouldn’t do with out a firmware hack. the GP2X is designed to play videos, music, view photos, and play games. The console supports emulators including GnGeo which emulates the Neo Geo; gnuboy2x, Game Boy Color emulator; MAME, an emulator of various arcade machines and DrMD, that emulates the Master System, Game Gear and Mega Drive. The player supports up to 2GB of Secure Digital Memory and has a built in TV out. Being a Linux player the GP2X has the ability to support Linux applications, the possibilities are endless.
The GP2X does have its drawbacks. It is still beta, and underpowered, although it can be overclocked. No Games have came out for the system naively, but may games have been ported over from Linux. The price is around ~189.99 and can be purchased at GP2X : Alternative Power Here are some specs:

Small little project with a Cubloc CB280 Start Kit evaluation board. This guy shows how easy it is to put together a simple alarm with board, keypad, alarm, and reed switches. The code looks very simple. I have been trying to get this old ass alarm to work in my house. I think it is time for me to try to make something with a PIC micro-controller. Stay tuned for a write up of my project in the near future.

Here’s one I found on You tube. The fountain is a smaller colorful version of the Bellagio in Las Vegas. The audio sucks.

“Nate True has developed yet another impressive hack using UV strobe lights, luminescent-dyed water, and a timer to create the illusion of water stopping in the air, slowing down the splashes into the pool beneath, and even travelling upward. You have to see it to believe it.”
Cool machine uses UV Leds to give a strobe effect to the fountain. fluorescein reagent powder is used to make the water fluorescent. A PIC micro-controller uses PWM to coordinate the liquid pump with the strobe Leds. By tweaking the electronics you can make the drops appear to be frozen in time or even move backwards. Nate has also started building a few fountains and selling them on eBay.

This unique robot is controlled by cockroach intelligence. The cockroach is placed on a small trackball which controls the movement of the robot. The idea is to create a pseudo-intelligent robot. The cockroach is flashed with ultra-bright leds. The leds provide feedback to the roach.

Surface mounted Electronics are becoming the more and more popular. They are small, cheap and are the preferred method used in most electronics. For the average electronic hobbyist, they also are a challenge to work with. Most the time you need a magnifying glass and tweezers just to handle them. They also don’t fit into solderless breadboards with out a carrier board. When you need to solder them on a PCB you will need some special tools. In the commercial world they’re are reflow soldering guns and reflow ovens. Commercial reflow ovens can run in the thousands of dollars.
Along came this tutorial from Spark Fun Electronics, that converts a cheep toaster oven into a re-flow oven. The tutorial also goes in depth on designing a controller to dial in the temperature on the oven. To the Hack..

Created as a graduate project by Eric Newman. The DrawBot was created to emulate the emulate the movement of the mouse. The DrawBot is controlled via a HID USB interface, using a Microchips PIC 18F4550 microprocessor to control everything. By using the HID interface the DrawBot can be programed to draw premade patterns of different coordinates or it could simply be controlled using a joystick or mouse. The DrawBot consists of five joints controlled by Futaba S3305 servos. The Futuba servos give the arm the stability and movement it needs. Be sure to check out the video on the website.

Tired of staring at those old incandescent lights in your factory car stereo. A blog article written by Jason at yorkspace.com take you through the process of adding super bright leds to your factory head unit. Once the factory face plate is removed, the incandescent bulbs can be replaced with blue super bright leds. With some leds, resistors, an some wire, you could change the overall effect of the factory head unit. This is a slick and cheap hack.

Think about it, you place a glass under the spout select a drink and “BAM”, a perfectly mixed drink. This project allows a user to select a mixed drink from a keypad, the bar then properly pours the right drink out a spout into a glass. The project uses pumps to distribute the right amount of alcohol. A computer built into the bar, which is running a visual basic program that controls the pumps. A video on the site that shows the bar in action.
