C64 Interface For Your Computer

January 23, 2010 by Caleb Kraft 24 Comments

Before we get started, lets just point out that this C64 was broken. He did not take a functional C64 out of operation for this. What he did do, was to build a hardware interface for for his VICE system. For those unfamiliar, VICE is a cross platform C64 emulator. [Simon] points out that the old games just weren’t as much fun without the original hardware. Having a broken C64 lying around, he put it to good use. It now acts as the interface for all the original fun stuff.

If you are a fan of the hardware, but just want to interface it as a normal USB keyboard, that is possible as well.

Bike Controller For Xbox 360

January 13, 2010 by Mike Szczys 11 Comments

ProjectExciteBike is on its second iteration of an exercise bike controller for Xbox 360. The controller takes pedal input from the cranks of the exercise bike. The sensing is handled by a ring of five hall effect sensors that detect a passing magnet attached to the crank. The sensor data is collected and processed by an Arduino which connects to a wireless Xbox 360 controller for output.

This version of the gaming device includes a fine adjustment widget. It uses a row of LEDs to represent the speed of the pedals and has a slider to adjust how much of an effect this has on the game. This is what we envisioned for the trainer computer we saw yesterday. Take a look at some game play video after the break and dig through the code if you have an exercise bike waiting to be recommissioned.

CES: Laser Instrument

January 8, 2010 by Caleb Kraft 1 Comment

This instrument caught our eye. It is a Laser device that looked like it could do midi input of some type. We played a little bit, but really weren’t too impressed. You know why? We’ve seen better.

Reverse Engineering The Telly Terminator

January 6, 2010 by Mike Szczys 17 Comments

[Oliver] received the Telly Terminator as a gift and decided to take a closer look at it. This key fob has two buttons; one shines an LED like a flashlight and the other turns off televisions. Sound familiar? Yeah, it made [Oliver] think of the TV-B-Gone as well.

He cracked open the case to find just a few components. The brain behind the IR signals is a Helios H5A02HP. Only a few pins are used for outputs so he connected a logic analyzer and recorded the signals. His writeup covers the process quite well. He takes a known IR transmitter protocol and compares it to the capture from the logic analyzer. It turns out that the fob generates 46 different signals and with further analysis concludes that there’s a chance the code used here is from an older version of the TV-B-Gone source.

Arduino Traffic Light

January 5, 2010 by Mike Szczys 28 Comments

[Rockwell] sent us an update on his traffic light hacking. Dedicated readers will remember seeing this legally attained traffic signal controlled through a parallel port from back in 2005. The new update swaps the old port for USB and adds several autonomous functions which are demonstrated in the clip after the break. The update includes a nice UI and some notifications for things like email, IMs, Reddit posts, etc.

He’s given control of the hardware over to an Arduino. Instead of building the board into the project he’s included just the parts he needs; an AVR running the Arduino bootloader, a crystal and filtering caps, and an Arduino serial to USB module for connectivity. The AC load switching is handled by three relays. The relays he links to are 12VCD rated coils. We think this should have pointed to 5VDC coils as that’s the voltage that the logic circuit are running at. Be careful with switching these AC loads, this traffic light isn’t a toy.

Make Your Own 3d Monitor

Don’t let this cruddy video fool you. [Sprite_tm] has done an amazing job here. He has put together a fairly simple way of creating your own 3d monitor at home. The basic principle is easy to get. You have to supply different angles of an object, on the screen, at the same time. [Sprite_tm] has done this by using transparency sheets, printed with a pattern to only show specific pixels. As you move your head, you see a different set of pixels, and therefore a different image. It’s simple, but it works. The system isn’t really new. Traditional 3d with polarized glasses uses a very similar setup. This system however seems like it is lacking in stereoscopic view however. When you move your head, you’re looking at a different angle, but still a 2d image of it. It would be really cool if he could somehow present each eye a different view, without polarizing filters and glasses. We’ve seen others do that with multiple screens, but that gets so clunky and can give most people a headache pretty quick. We also think we are about to see a flood of face tracking perspective modification, especially with project Natal and similar technology emerging.

The Harlequin Project

December 11, 2009 by Caleb Kraft 15 Comments

This impressive little mod is quite fantastic really. [pakkei] has constructed the Harlequin, a home-made version of the Microsoft courier. This was a stock Dell mini9. Now, coupled with a display link touch screen monitor that happens to be identical in size and resolution to the original, it has become a new device. He has loaded Windows7 and is currently working on a case that can hold all the bits a little more organized than what you see above. We can’t wait to see this finished.
