Gorgeous Portable N64 Built To Order

January 25, 2010 by Mike Szczys 59 Comments

[Hailrazer] is at it again with a new portable N64 build. He’s done the impossible by improving upon his last design. The LCD screen is now mounted flush for a cleaner and smaller case. The controls draw from a lot of different sources; a gamecube stick for durability, a 3rd party N64 controller for buttons, and a PlayStation controller for the shoulder buttons that serve as L, R, and Z (either hand). There is a breakout box that allows two controllers to be plugged in. Combine this with the TV out feature and it acts as a console or a handheld. His in depth demonstration is embedded after the break.

The build log (linked above) details every part of the hack so that you can try to do this yourself. The relocation of the expansion slot requires patience and solid soldering skills. The case work is an art in itself. We speculate that this commission comes somewhere close to $1000 but it’s hard to put a price on quality craftsmanship. We’ve seen smaller, but these features and finished look can’t be beat.

AVR Tetris

January 14, 2010 by Mike Szczys 16 Comments

Tetris, the timeless classic, is one of those concepts that someone will try to run on every conceivable hardware platform. I took on the challenge of programming a Tetris clone from the ground up using hardware I had on hand. At the heart of the build is an ATmega168 microcontroller. The game displays on a KS0108 128×64 LCD module with five momentary push switches to provide directional, rotational, and input controls. You can see the resulting monochrome action embedded after the break.

I had several goals in mind while writing the code for the game. I wanted the code to be portable so that the size of the board and type of screen used could be easily changed. With that in mind I developed the trunk for a Nokia 3595 cellphone screen and a parallel branch for the graphic LCD. Originally I was working with an ATmega8 but upgraded so that I could operate at the 3.3v the cell phone screen required.

The firmware for the graphic LCD branch compiles to just over 6 kB which means it can still be run on a mega8. Also, the ATmega168 is the same processor used in the Arduino Duemilanove so another Tetris port is not out of the question. I just got a hold of my first Arduino so we’ll see if I find time to start a new branch in the code.

CES: Glove Input

January 9, 2010 by Caleb Kraft 8 Comments

The peregrine looks like it could actually be a useful tool. We’ve seen several people make glove input devices over the years and this looks like a quick and easy way to get one going. It touts over 30 touch points that are user programmable. Really, it works more like a keyboard wrapped around your hand than any kind of motion or flex sensing. It could probably save you some time if you are headed that direction, but at $250 you might just want to build your own.

[James] – For those looking to make your own, Adafruit offers both flex sensors and force sensitive buttons that could help you work on something like this.

Update: More Pink Wireless-terminal Hacking

January 6, 2010 by Mike Szczys 13 Comments

[Dave] poked around inside of an IM-ME wireless toy and compiled his findings. He read about the device when we covered it in November and picked up a couple to see what he could do. He patched into the debug port in the CC1110 processor and enabled it by performing a chip erase. He then began mapping out how the processor connects and communicates with the qwerty keyboard, the wireless radio, and the LCD screen. The board is full of test points which make the hardware easy to access. [Dave’s] experiments show that this hackable device is full of potential so let’s see what you can do!

TI-nspire Hacked

December 31, 2009 by Mike Szczys 17 Comments

The regulars at the United T1 forums keep them coming, this time hacking the Texas Instruments Nspire graphing calculator. We enjoy seeing the exploits that unlock the backend of these types of devices. The difference this time is that the hacking continues even though Texas Instruments has shown that it intends to protect the security of their devices using the DMCA. The Nspire thread linked above discusses the DMCA concerns just a bit but it seems obvious to us that running your own code falls under the umbrella of the act. The exploit package hasn’t yet been posted, but if you want it make sure you check back regularly before the take-down order comes in from TI.

PS3 Wireless Visual Interface

December 29, 2009 by Mike Szczys 26 Comments

[Technott’s] at it again, this time extending the Playstation 3 with a wireless interface. This handheld isn’t actually a PS3. It provides a wireless connection to your PS3 to receive audio and video, as well as to manage controller data. Think of it as a wirelessly tethered handheld that allows you to play Playstation when your wife is watching the Real Housewives. This is similar in size to his Xbox 360 WVI but the case shape and appearance are a big step up (not that we disliked that one). We’ve embedded a video tour of the device after the break.

Composite Video Output From Chumby

December 29, 2009 by Caleb Kraft 4 Comments

[bunnie] posted this pretty slick way of getting composite video out of a Chumby. The Chumby is an open source connectivity device that has already seen some decent hacking. This modification, done by [xobs] isn’t too difficult. It only requires patching into some pads on the motherboard and loading a custom kernel to support the external output.
