Gaming On An IBM XT Using An NES Controller

December 24, 2010 by 27 Comments

[Frode] felt that using the keyboard for gaming on his old IBM XT computer was simply too noisy. He came up with a much quieter way to game by building an XT adapter for an original NES controller. If you haven’t explored the communication protocol used by the NES peripherals this is a great way to learn. Inside you’ll find a CMOS shift register that captures button states when it receives a latch signal. With that in mind [Frode] came up with a circuit to gather the bits from the controller, and generate input commands using the XT keyboard protocol without using a microcontroller. All of this is explained in the demo after the break.

Most of the NES controller hacks we see permanently alter the hardware. It’s nice to see one used without cracking it open.

Making Music With Tech Stolen From Predator

November 25, 2010 by 17 Comments

This is a second generation Manta, a touch-based controller with visual feedback made to use with Max/MSP. The hexagonal size and the patterns seen in the video after the break remind us of the arm-based computers the Predators sport in the movies. Like the previous generation, this controller can tell not only which of the 48 sensor you’re touching, but how much of your finger is touching it. The sky is the limit on extensibility with this type of data, but for now you can just try out the pre-built plugin and see how it goes. New with this rendition of the Manta is the use bi-color LEDs which adds another lay of interaction with the PC to which this is tethered.

If you don’t mind giving up the touch controllers for good old push buttons perhaps this Harmonic Keyboard is right up your alley. Continue reading “Making Music With Tech Stolen From Predator” →

Chest Freezer Temperature Controller

November 5, 2010 by 11 Comments

[Mikey Sklar] finds himself in need of a temperature regulated refrigerator for fermenting foods like yogurt, kimchi, bread, and beer. After some testing he found that by building his own controller he can get a chest freezer to outperform an upright refrigerator at this task by 2-to-1.

The controller is based around an ATmega48. It includes a remote temperature sensors which you can see connected to the lower left header in the image above. On the back of the board there’s a relay used to switch the freezer’s power on and off. [Mikey] is selling a kit but the hardware and software for the project are both open source so build it yourself if you have the know-how.

A chest freezer is a great place to store Cornelius kegs… we’ll keep our eyes open for one.

SNES Controller Dock For Dell Streak

November 4, 2010 by 9 Comments

The Dell Streak is an Android tablet. [Collin Meyer] wanted to use an original SNES controller to play emulated games on the device. What he came up with is a controller that is a dock for he handheld.

Several things have to come together to make this happen. The Streak uses a standard PDMI dock that connects to a computer via a USB connection. [Collin] repurposed a sync cable by connecting a couple of pins on the dock connector which forces the device to use USB host mode. From there he used a Teensy microcontroller to convert the SNES controller into a USB device (very similar to this hack). The Teensy and shortened sync cable find a new home inside the SNES controller body and, in the video after the break, it looks like he used something like sugru to add a bit of support for the Streak.

PC Game Controller With A Touch Of Class

October 26, 2010 by 23 Comments

The above is a specially designed game controller made by [Giorgos] solely for the RTS game Men Of War (now that’s dedication to a game). [Giorgos] started off with a rough breadboard and 11 buttons. Slowly overtime he included a joystick, countdown timers, and the wonderfully lit case. Under the hood is a couple of PIC microcontrollers multiplexing the switches, LEDs, timers, and also interfacing with the computer via how is it not dead yet PS/2 port. The build log is a very detailed read and well worth it, even if you’re not planning on making a custom controller. [Ben Heck] better watch out, there is a new controller making enthusiast on the loose.

NES Controller Gets A Rumble Pak

October 11, 2010 by 16 Comments

Add some feedback to an original NES controller by making it vibrate. This feature is often known as Rumble Pak, a controller add-on for the Nintendo 64 which vibrated as a game feature. This version adds a small DC motor (in the upper right) with a screw soldered off-center to the motor shaft.

[Andy Goetz] and his friend built this as a robot controller, taking advantage of the latch and clock pins. Normally, nothing happens while both pins are held high, a signal that they easily patched into using an AND gate. This is actually a neat find, as the addition of an internal microcontroller could add bi-directional communication when the latch is high and the clock is strobed.

Making Your Own Lithium-ion Batteries

September 27, 2010 by 23 Comments

You can make your own lithium-ion batteries if you have a source for individual cells and a control board to match your desired voltage levels. [Bill Porter] put together a quick tutorial where he makes a 14.4V 2.2 AH battery for about $10. He picked up a set of cable-modem backup batteries (used to make sure your bundled phone service doesn’t quit working when the power goes out) and tore out the cells. After reconfiguring the connections and swapping out the controller board the original 8V battery is now 14V. This doesn’t take into account any problems with battery life and charge leveling, but that’s a whole different tutorial waiting to happen.

If this type of battery hack is child’s play to you, take a look at a more involved lithium iron phosphate build.
