Update: Most Interesting Game In 64 Pixels

February 19, 2010 by Mike Szczys 25 Comments

[Brad] has continued working on the Super Pixel Bros game. We saw a glimpse of this a few months ago but he’s added a lot since then. The game now has enemies; one type is similar to Bullet Bill, another type drops from the sky and walks toward you, kind of like a Goomba. Game play is quite responsive and it’s amazing what he has accomplished with such low resolution. In the video after the break [Brad] mentions that a friend is working on sound effects for jumps and block breaking. We’re assuming that the audio track in the background is already coming from the LEDBOY speaker.

Which reminds us, if you haven’t checked out the hardware, do so now. That enameled wire mess makes us shudder just a bit. There many be a kit version coming that will save you the point-to-point soldering madness. If that’s part of the fun for you keep an eye out for the forthcoming release of the hardware schematics.

Leapfrog Didj: Followup

February 3, 2010 by James Munns 25 Comments

Yesterday we mentioned the Woot! sale of the Didj, and we had some comments and emails from readers who had purchased one. We couldn’t resist either, and ordered a couple to take apart and modify. We will probably be following the work laid out by [Claude Schwarz], who seems to be one of the leading hackers on the scene. [Claude] has done some work in porting the GP2x libraries to the Didj, which gives a tremendous head start to anyone looking to have a working game system any time soon. There will also be a build log for everyone to follow along at home, and contribute what you want and have, as well as a follow up How-To when a working system is attained. Happy Hacking, everyone.

Leapfrog Didj: Handheld Linux On The Cheap

February 1, 2010 by James Munns 64 Comments

Today our good friends over at Woot! are selling the Leapfrog Didj, a low cost educational toy aimed at little kids. Lucky for hackers out there, the Didj is actually a linux device, and gaining serial console access is as easy as soldering two wires. The documentation out there is a little outdated, with a number of broken links and stale wikis, but $25 for a portable linux device is a hard deal to beat. A list of sites which might be helpful are listed after the break, as well as the hardware specs of the Didj.

Let us know if you have played around with hacking the Didj before, and if you have any tips for other readers. Don’t forget to tell us what you do with the Didj as well!

Thanks to [Mark] for the tips and the hardware details.

IM-ME Screen Reverse Engineered

February 1, 2010 by Mike Szczys 3 Comments

[Dave] figured out the command set for the IM-ME terminal. It took a bit of sleuthing to get this pink plastic peripheral to give up these secrets. He used an oscilloscope to sniff out the SPI connections, then used a hacked IM-ME to capture the traffic from a factory-fresh unit. He managed to extrapolate how write data was being sent but he still couldn’t figure out how commands were differentiated from that data. With the info at hand he searched around the interwebs to find that the screen uses an ST7565S controller. Now he’s got custom firmware to make the LCD display do his bidding and we’re wondering what’s next?

Add A Bluetooth Terminal To Your Kindle

January 31, 2010 by Mike Szczys 6 Comments

This is an Amazon Kindle DX with a Sparkfun Bluetooth Mate stuck in it. [Darron] hacked the two together in order to have a wireless serial terminal on the device. There are three big pads in the middle of the Kindle PCB labelled GND, RX and TX, making it easy to figure out those connections. Getting voltage was a bit more difficult. He managed to find 4V coming off of one side of the Kindle’s wakeup switch which works well because the Bluetooth Mate has a voltage regulator on board. To protect the Bluetooth module he modified it to pull-up the TX from the on-board regulated 3.3V rather than the 4V coming in from the Kindle.

He’s also been doing some software work on the device now that he has easy access to it. Along the lines of the Ubuntu-on-Kindle hack from September, he’s compiled QT for the Kindle and written a couple of programs such as Sudoku to show that it works.

Nanotouch: A Tiny AVR Media Thing

[Rossum] is at it again. This time, he has created a super tiny media device to get us drooling. You might recall him from the 8-bit device we showed you before. The Nanotouch is roughly the dimensions of a 96×64 OLED screen(slightly larger than a quarter), with about 1/3 to 1/2 of an inch of stuff packed behind it. The screen itself is mounted atop 4 buttons. This allows you to depress the screen edges for navigation. He does mention that this design needs a little work to prolong the life of the screen, but we really like the intuitive way of navigating. At its heart is an ATmega32u4.

We thought his last version was fantastic, but this one has us enamored. He states he’ll publish schematics and code, as he did before. We just didn’t want to wait to share.

[thanks Joakim]

Palm-sized Atari 2600

January 26, 2010 by Mike Szczys 9 Comments

[The Longhorn Engineer] is working on a portable Atari 2600. Instead of taking the old gaming system and cramming it into a portable form factor he’s designed his own circuit board in a new-hardware initiative he calls Project Unity. The handheld will include everything you need to play, including video, audio, controller buttons, paddle control, and a cartridge connector. For the demonstration, embedded after the break, he’s using the Harmony Cartridge to store his Atari ROMs but do note that the system is designed to use cartridges rather than work solely as a game jukebox.
