We’ve been eyeing Seeed Studio’s DSO nano digital storage oscilloscope with a mix of intrigue and skepticism. A pocket-sized $89 storage ’scope? This is a joke, right? Hack a Day reader [Blair Thomson] has written a thorough review based on his experience with one of the beta test units, and it might be a winner after all.

[Blair] feels the unit compares favorably to buying a similarly-priced secondhand analog oscilloscope. The DSO nano wins major points for ease of use, a good range of functionality, and of course the whole portability thing (the enclosure is a repurposed portable media player). Can’t say we’re entirely convinced though. As a single-trace ’scope with 1 MHz bandwidth, the DSO nano may be extremely limiting for anything but basic hobbyist use…which, to be fair, is exactly how they’re marketing it. We can see a place for this the same way there’s a place for $10 multimeters — an inexpensive, toss-in-the-toolbag second ’scope to quickly test for vital signs, something that might complement but not replace a good bench unit.

OpenMoko, the company behind the FreeRunner open-source phone, released their latest product today: WikiReader. It’s a small mobile device for browsing Wikipedia. Rather than use a wireless network to pull data off of the web, it has local copy of the database on a 8GB microSD card. This approach has been used before, and it lets the WikiReader be compact and really cheap. It uses a Kindle-esque touch-screen display that allows it to run on 3 AAA’s for about a year. The device itself costs just $99, but you can choose to receive updates by snail mail for just $29/year. Alternatively, you can just download the +4GB file and dump it on the card.

Like the FreeRunner, this project is also open-source. The code isn’t available yet, but they say it will be released soon. With luck, the device will be really easy to hack.

[Ariel] liked the look of the Muji wall mounted CD player. He set out to build his own, posting a how-to that documents his project. The custom paperboard case contains a portable CD player, two portable speakers with amplifier, and a pull-string switch to turn it on and off. With mp3 players sending portable CD players the way of the dodo, and with the proliferation of powered mini-speakers this is a thrift-store build waiting to happen.

Not content with Nintendo’s current portable video game offerings, fifteen year old hardware hacker [Xteaphn] (pronounced “Steven”) has come up with a series of hardware modifications to make a battery-operated Wii console. The hacked console features a folding laptop-like screen, which apparently includes the IR emitters necessary to make the Wiimote operate properly, as well as a set of tiny stereo speakers. To show how tiny the modified console is, [Xteaphn] provides size comparisons with thirteen- and fifteen-inch laptops as well as with a classic Nintendo Game Boy. The only potential hindrance to its long-term durability, as best as we can tell from the video, is that the battery pack and its associated connecting wires hang crudely off the back of the console like a sort of electric colostomy bag.

Check out [Xteaphn]’s YouTube video after the break.

A month ago, we reported that Nintendo’s new DSi portable didn’t work with any of the current crop of flash cartridges. Things didn’t look good for homebrew. Here we are a month later and looking at the release of the Acekard 2i. It’s the first DSi compatible flash cartridge. The features appear to be identical to previous versions and we expect other manufactures will be updating their product lines in short order. You can find a video of the Acekard 2i after the break.

These carts may exist because of pirates, but we happily use them for homebrew. There are a lot of great programs out there; here’s a list of 24 apps that are dedicated to music creation. You can run Linux on it too. It’s as easy as copying a file to a flash drive. If you have a DS and aren’t using homebrew, you’re wasting it. We’ll be picking up a DSi as soon as they’re in the US (they’re region locked).

[skeezix] has got his hands on one of the first Pandora dev kits to make it out the door and took a few photos. This is 1 of the 20 MK2 devboards that were produced. Although, not final it certainly is close to the version they’ll be shipping. Pandora is a Linux based portable game console. The main chip in the clamshell device is a TI OMAP3530. It has OpenGL hardware acceleration and an 800×480 touchscreen. A QWERTY keyboard is included along with analog and digital game controls. WiFi, bluetooth, USB host, TV-out, and dual SDHC card slots round out the package. The team has already presold 4000 devices.

Evil Mad Scientist Laboratories have just announced the release of the Meggy Jr RGB, a fully programmable handheld console with an 8×8 RGB LED matrix display. Like its big sisters Peggy and Peggy 2.0, the Meggy Jr is driven by an ATmega168 microcontroller and is made up of a bank of fully addressable LEDs. Unlike its siblings, the device boasts six buttons and the ability to be mounted inside of a custom case (or “handle set”) constructed from plastic or wood, drastically altering the look of the console. Using the popular open-souce Arduino environment, users are able to write custom software for the device. While it works great as a game console, of the many possible configurations and suggested uses, we think “disco floor for your Lego minifigurines” is the most amusing.

The latest version of the Nintendo DS, the DSi, has officially launched in Japan. It features larger dual touchscreens, dual cameras, and an SD card slot. The members of GBAtemp.net have decided to tackle the most important question: will it run homebrew? Current DS systems just need a purpose built flash cartridge to load homebrew software (usually stored on MicroSD). Forum members have tested at least 10 different flash carts, and none of them worked. While not completely exhaustive it’s proof enough to us that current generation carts will not work. We hope this is something that can patched with a new firmware. Most carts load their firmware off the flash, so upgrades are easy. The blocking of homebrew maybe a side-effect of Nintendo’s announced region-locking on the DSi.

We hope this gets sorted out soon. Maybe we’ll see hackers figure out how to take advantage of the SD slot instead. If you’ve got a Nintendo DS, there’s no excuse not to be playing with homebrew. It’s as easy as copying files to a card. We’ve had success with the DSTT, which you can find on DealExtreme for just $10.

[acabtp] has already started hacking on his Dell Mini 9. He wanted to add GPS functionality, but didn’t want a dongle or anything external. After ordering the smallest GPS unit he could find, he found a place to wire it in internally. The end result had no bearing on the external looks of the computer. I wonder if he used the modification guide dell released?

Marketed as direct competition for the EEEPC, we’ll probably start seeing a lot more hacks for these. We’ve already seen the EEEPC taken hacked more than we ever expected.

[jon barber] pointed out another great project on the benheck forums that hasn’t gotten much attention. [techknott] built a wireless video interface for his Xbox 360. Think of it as a sort of video game thin client. It has the form-factor of a portable but doesn’t include the 360’s components. Instead it has a 1.2GHz A/V receiver and the guts of a wireless controller. The specific transmitter was chosen because it wouldn’t interfere with the 2.4GHz controller. The power supply is two 2600mAh batteries running at 7.5V with a built in charging circuit. The draw from the screen is ~500mA. The entire unit is 1 inch thick.
