Update: IR Controlled Lighting

April 26, 2010 by Mike Szczys 11 Comments

[Muris] is back with another infrared controlled lighting hack. When we checked in with him last year he was showing off an IR controlled dimmer module. Now he’s back with this device that is CFL friendly. Because standard CFL bulbs are not dimmer compatible he’s adapted the project away from dimming and toward switching. The new design still uses an infrared remote but now it can turn two devices on and off again or toggle between them. Our favorite part of the build is that the PIC based device can learn the codes of whichever remote you choose, rather than having to rely on one specific type of remote.

Wii Remote Controlled Balancing Wheel chair

April 25, 2010 by Mike Szczys 10 Comments

The Personal Mobility Robot (PMR) has a chair for a passenger and balances on two wheels like a Segway. Now the clever folks at the University of Tokyo have added Wii remote control to the platform in a full-sized version of the Segwii. We understand that adding Wiimote control to anything isn’t exactly groundbreaking at this point. That being said, if using stock hardware can increase the quality of the user interface on something like a wheelchair, while decreasing the production cost at the same time, we’re all for it.

Custom Controllers For PlayStation 3

April 25, 2010 by Mike Szczys 22 Comments

[Matlo] worked out a way to use a PS/2 Keyboard and USB mouse with a PlayStation3. The hard work is handled by a Teensy board, which is becoming a popular choice with controller hacks. It interfaces with the keyboard and mouse, translates their input, and sends joystick button commands to the PS3. He is limited to mapping the inputs from a PS3 controller but that is still enough options to work beautifully with first person shooters, especially if you’re used to gaming on a PC instead of a console. If you want to give this one a try, head over to the google code page to download the source code.

RF Transmission In The 9 KHz Band

April 25, 2010 by Mike Szczys 31 Comments

[W1VLF] is on a quest to communicate over long distances with a 9 kilohertz transmitter. He built this giant coil with that in mind. A round concrete form was used as a base and wound with magnet wire by hand. We’d recommend building an automated winding device, but this method seems to have worked. Operating at 50 Watts on the air-core coil at 8.97 KHz he was able to pick up the signal at a distance of 5 kilometers. It’s not breaking any overall distance or portability records, but on a project like this the quest is where the fun is at.

Rendering And Blendering In A File Cabinet

April 24, 2010 by Mike Szczys 39 Comments

The Blender Foundation has just received a new render farm. It came in the form of a four-drawer file cabinet something akin to the popular Ikea clusters. Each draw holds four motherboards, power supplies, and hard drives and the whole cabinet will eventually add up to a 16-node cluster. Join in on the geeky excitement by watching the delivery and unpacking video after the break. We love it when organizations share the details on the hardware they use.

Apple IIe Twitter ticker

April 24, 2010 by Mike Szczys 18 Comments

A hand input bootloader and a custom communications protocol are what bring the Apple IIe Twitter ticker to life. [Chris Yerga] bought the decades-old machine for $20 at a flea market. Having just completed his TweetWall he decided to adapt the idea for the 1 MHz machine. He manually input a 50 byte bootloader that would let him dump programs into memory via the joystick port. From there he rigged up a connection with a USB FTDI cable. Now the images and text are processed by a modern-day machine and fed to the Apple IIe at 3600 baud. See this in action after the break.

Driving The Car Without Going Anywhere

This video game controller is a factory fresh VW. Much like the racing simulator from earlier in the week, the video game data is being displayed on the instrument panel. This takes us to a much higher level now because control for the game is taken from the car’s CANbus using and ODB-II connector. If you don’t speak in automotive jargon, that means that the sensor readings from the steering wheel, shifter, and pedals are being picked up and exported as joystick commands to the PC running the driving game. The only place the experience uses a substitute for the real thing is the sound, which is being played through speakers instead of emanating from under the hood. Looks like you just need to add a projector and screen to your garage in order to turn it into the hottest new gaming device.
