There’s nothing wrong with portable NESs, Super Nintendos, N64, or even a portable Sega CD. What about a portable version the oft-maligned Atari Jaguar, though? [Evil Nod] pulled it off, and it looks great.

The build is fairly standard for a portable console. A PS1 screen is used for the display, and a cut up and re-wired controller provides the input. From what we see on the build log, moving the 104-pin cartridge slot onto ribbon cables was an exercise in patience. The case is absolutely phenomenal with a textured finish we would expect to see on an early 90s console. Of course, [Nod] kept the numeric keypad; there was space left over anyway.

We can’t rag on the Jaguar or [Nod]‘s build. It’s a great execution and there’s an impressive library of games that include Worms, Rayman, Doom, and Myst. Still, we wonder what the build would look like with the Jaguar CD-ROM attached.

[Rossum's] still coming up with great ways to use his microtouch hardware. This time, he’s taken his inspiration from Amazon’s announcement that a full-color eBook reader (and movie player) is on the way. Judging from the video after the break, his fully functional reader is a big win for the device.

You’re probably familiar with the hardware, an ATmega644-based board connected to a touch sensitive LCD screen. You can make your own or buy one pre-assembled (but currently out-of-stock). The board has a microSD card slot making it quite easy to add books to the device. At the start of the project [Rossum] thought he might be able to read ePub files directly, but the embedded images, and unzip function needed to open the package file is a bit too much for the 8-bit processor’s restrictions. One simple step does the trick. A helper script can be used to format the files before transferring them to the device. This does the unzipping, scales the images, and repaginates the text into a format friendly for the display size.

Now if we only had a nice little case to house the hardware we’d be in business.

[Retro Brad] has come a long way with his 8×8 gaming device which he calls Super Pixel Bros. The newest rendition has a fab house PCB and freshly rewritten code. The game is still played on an 8×8 LED matrix, but it looks like he’s sourced a version with square pixels, which is a nice touch since he was inspired by the block-based Super Mario games. Also new in this version is the character LCD screen which displays score, level, and life information. But it’s not just the shiny new hardware that’s different, he’s rewritten the software in Swordfish Basic to run on the PIC 18F4550. The new code allowed him to tweak how levels are loaded and stored. He’s even written a level editor and has finished 20 levels thus far.

The demo after the break does a great job of showing off the hardware and the game play. He’s added a lot, including enemies, the ability to shoot fire, and of course the common moves of jumping and breaking blocks is all there. He mentioned that the fab house he used is selling boards for around $5 and he’s looking into the possibility of getting a kit service up and running.

His progress since we last checked in on the project is quite impressive.

Here’s an unbelievably real-looking R2D2 replica driven by a PS2 controller with an Arduino inside that plays sounds from the movies. Too bad we couldn’t find any more details about it. [Thanks Bill]

Server build time-lapse

[Justin] and his colleagues spent five days upgrading their server by building a 29-unit cluster. Lucky for us they set up a web-cam to capture the process.

Cockroach computer

Behold this working desktop computer, complete with monitor and mouse. We’re not sure how it was done, or what it’s for, but worth a peek just because of its size. [Thanks Harald via Dvice]

Modelling self-assembling viruses

A 3D printer and magnets were used to build this model of a self-assembling virus. Shake the jar and it falls apart. Shake a bit more and it’ll rebuild itself… it has the technology.

Tardis cufflinks

[Simon] is exercising his geek chic with these Tardis cuff links. The Doctor Who inspired accessories were made from a model railroad telephone booth.

[Luke] wanted an arcade-style controller that he could use for some gaming at home. He decided to use a portable game emulator as a base and then added his own joystick and buttons along with a custom case.

The donor hardware is a Dingo A320. It’s a nice little handheld with a 2.8″ screen, and plenty of potential to emulate games like Donkey Kong seen above, or to play homebrew. It’s even been the target of some RAM upgrades we looked in on in the past. The best part for [Luke's] project is that it includes a video out port.

In the clip after the break you can see that [Luke] now has a compact controller with a huge arcade joystick, four buttons on the top surface, and the rest of the controls all around the edges of the enclosure. The video out option is selected in the menu system, so he preserved the original LCD for use during configuration.

Console hacker [techknott] has a skill set that is quite possibly second to none. We do love [Ben Heck] and think that his portable consoles are beyond awesome, but you’ve got to check out this portable GameCube [techknott] put together.

While the construction details are pretty sparse, the video below shows off the bulk of the portable ‘Cube’s best features. Far smaller than his Flip-Top GameCube or Dreamcast portables we’ve featured in the past, his new handheld sports a wider screen and is completely disc-less. While the legality of booting backup copies of games from an SD card is something we won’t delve into, we do like the concept.

The console itself is probably only about one and a half times the width of a standard GameCube controller, and while it doesn’t sport an internal battery pack, we wouldn’t turn one down. Besides, who wants to play GameCube outside? With one of these in hand, we are more than happy to keep our pasty selves indoors, thank you very much.

The only complaint we have here is the lack of build details. [techknott’s] handheld consoles are pretty amazing – we just wish that we could see how the magic was made!

Be sure to check out the video below to see the console in action.

[Thanks, Dave]

If you’ve ever thought the Kindle keyboard was a bit cramped you’re not alone. [Glenn's] been working on developing an external keyboard for the Kindle for quite some time. It may not make easier for everyone to use, but he’s motivated to improve usability for his sister who has Cerebral Palsy.

We see a lot of keyboard hacks that solder straight to the pads under the buttons, but for a compact device like the Kindle this would really mess things up. Instead of going that route, [Glenn] sourced a 20-pin Flexible Flat Cable and breakout board that match the internal Kindle connector. The prototype seen above uses a TS3A5017 serial multiplexer chip to simulate the keyboard button presses. That multiplexer is driven by a Teensy++ microcontroller board which is monitoring a larger set of buttons on the V.Reader seen above. Check out the video after the break for a brief demonstration, then look around at the rest of [Glenn's] blog posts to view different steps of the development cycle.

Although Hack A Day is no stranger to console conversions, this portable N64 build is worthy of note. The article itself is in Spanish, but for those that don’t speak the language, the steps and components necessary are well documented in pictures. There’s even a video of the finished product after the break.

What is especially interesting about this project is the professional looking build quality of the finished product. One might think it’s a custom injection molding job or possibly 3D printed, but everything is done with only glue, filler, and paint. A controller and console is hacked up to provide the raw materials for this build. An expansion pack is even attached to this console for good measure.

Power is provided by a 6800mA battery, and the console features a generous 7 inch display. A good wiring schematic is also provided in this article, so maybe it will inspire other quality console hacking in the future.

Additionally, here’s another N64 portable console hack if one isn’t enough.

There’s very few users out there who actually have their hands on an Open Pandora Console. But the ones who do might find this hack useful for getting TV out up and running. It’s actually not hard at all, but if you don’t want to alter the hardware on the device you’ll first have to find a cable plug that will fit the EXT jack. This proved more difficult than it needed to be, since TI carries the connector but only sells them in multiples of 2200. A group buy was organized and we’d bet you can still get in on that action.

The connector in question carries TVout1 and TVout2 conductors. These correspond to the Luminance and Chrominance signals needed for the S-video protocol. But [MarkoeZ] wanted to use a composite connection. Turns out that’s not hard either, he hooked up the ground from the plug to the ground of the RCA jack, then connected both video lines to the center conductor, making sure to add an inline 470pf capacitor on the Chrominance side. Check out the demo video embedded after the break to see the final product.

Instructables user [flapke] has a Kobo eReader and wanted to add some solar cells to it in order to charge the battery for free. The modification is similar to others we have seen recently, though his work was done so well that it almost looks stock.

He started out by sourcing a pair of solar panels from DealExtreme that purported to supply 5.5v @ 80mA. Like most of us are inclined to do, he tested them before use and found that they actually put out around 50mA instead. While the performance was a bit off, they still fit his needs pretty well, as the charge current needed to be at or less than 100mA to avoid damaging the battery.

He opened the Kobo’s case, and carefully removed a section of the back panel to make room for the solar panels. Once they were soldered together in parallel, he wired them to the eReader’s battery through a Schottky diode to prevent the battery from draining.

While we think his solar modification is a great way to ensure that he never runs out of juice while reading by the pool, we would certainly add a bit of extra charge circuitry to ours to prevent damage to the battery. What do you think?

After about six weeks of testing [Yifanlu] has released a stable version of the Kindle 3 firmware for use with Kindle 2 hardware. Everything seems to be working just fine with the patched firmware. We immediately jumped to the conclusion that the upgrade must run pretty slow on the older hardware. [Yifanlu] addresses that assumption in his post. The Kindle 2 hardware is not as fast as the Kindle 3, but it sounds like the upgraded firmware is no slower than the stock firmware was on the older units.

Since the firmware is proprietary, the upgrade method requires that you own both Kindle 2 and Kindle 3. Three scripts will pull the firmware image from the older hardware, copy it over to the new hardware and patch it at the same time, then copy the fully patched package back to the old hardware for use.

After the break you can see a video of a Kindle DX running 3.1 firmware. There’s also a link to the Reddit post where commenters have linked to pre-compiled versions of the patched package.

We love to see Doom ported to new hardware because it usually means that someone has found a way around the manufacturer’s security measures. But the most exciting thing for us to see this time is that Doom II is played on an epaper display. These are notorious for slow refresh rates, but as you can see in the video after the break, this one achieves an admirably fast page redraw.

According to a translation of the original forum post, the PocketBook 360° Plus boasts a 5″ E Ink Pearl screen, 533 MHz Freescale i.MX35 ARM11 processor, 128 Mb of RAM, 2 gigs of storage, and WiFi. No word on price for one of these babies as it seems they’ve not yet been release. Remind anyone of the green monochrome goodness from the original Game Boy?

[David] recently wrote us to share the portable Nintendo 64 he constructed with the help of the friendly people over at the ModdedbyBacteria forums. We are no strangers to N64 portables, as you may have noticed, but this one was just too good to pass up.

Sheathed in a metallic blue case, this console is an instant standout among the other portable N64 mods we have seen. As you would expect, he trimmed down an N64 console board and some various controller bits in order to fit them into the case, finishing it off with a 5″ PSOne display panel. A small fan protrudes out of the back side of the device, which seemed out of place at first. However, it not only keeps the console cool, but it can serve as a bit of a “kickstand” as well, if the console is placed on a flat surface. [David] also added a dongle for the bottom of the console, which allows him to use an external N64 controller if he so desires.

To be honest, one of our favorite features is that the game cartridges do not stick up from the back of the case when inserted. He included just enough room to allow the game to be completely hidden while playing.  Nice job!

[Hailrazer] found a Game Boy Advance carrying case in his closet and thought he could pull off an N64Boy Advance in a few weekends. Despite the fast build time, [Hailrazer] built something that wouldn’t look out of place sitting on a shelf at a toy store.

This isn’t the first time we have covered an N64 Advance portable gaming system that uses a GBA carrying case, but this hack keeps the original styling of the Game Boy Advance without all the epoxy, bondo and sanding. Inside is a 4.3″ screen, GameCube joystick, N64 expansion pack, and enough Li-ion to get 5-6 hours of play time. The build doesn’t include a D-pad because [Hailrazer] doesn’t use that while playing. It also doesn’t have controller or A/V ports, because he doesn’t, “want to sit around with friends playing N64 on a 4.3″ screen.” A very pragmatic build, indeed.

We love seeing people re-purpose odd bits of plastic they have lying around, so we’re wondering when someone with an Original Game Boy Carrying Case will build an NESBoy. Video after the jump.

There have been a fair share of portable video game console conversions over the years, but few tug at our retro-loving heart strings more than this one. Modretro forum member [Mario] constructed a fantastic looking portable Atari 2600 using a Flashback 2 Atari console clone.

He hacked apart the Flashback board to fit inside a small plastic case, then added a 3.5″ LCD screen, as well as some donated controller bits from other portable game systems. A pair of rechargeable batteries were added along with a small amplifier and speaker for sound.

While the Flashback comes with 40 games built in, he really wanted to add a cartridge port, so with the little bit of space he had left in the case, he did just that. When everything was finished, he sprayed on a few coats of retro orange paint and called it a day. Really the only thing that’s missing is some nice fake wood veneer and maybe some shag carpet.
