[ZodTTD] has released a Nintendo 64 emulator for iPhone. It is available (for a price) at the Cydia store and can be installed on jailbroken iPhones. The video shows Wii Remote support as a control interface that uses both buttons and the accelerometer, an addition since we last looked at his work. There is no word about nunchuck functionality, a must if you’re going to try to 100% Mario64.
[Marcan] picked up this device on the cheap and is working to reverse engineer the controller. This media player is an off-brand Chinese model that can be had for the low-low price of $33.97 with free shipping. That’s worth it just to scavenge the parts for other projects, but the challenge here is to hack the controller because a datasheet was never produced for it. Warm up your logic analyzer, check out the wiki, and you can be pounding away at this ARM926EJ-S based system in no time.
The call to arms comes from [Marcan's] blog. You may remember him as the guy who is working to solidify iPhone sync in Linux or… what else did he do? Oh yeah, he had this little project called the Wii Homebrew Channel a while ago. Get involved and you can learn from some folks who really know what they’re doing.

[Jared] had a bunch of lasers left over from a previous project that he put to use by producing this laser harp. The look of it reminds us of a very small Koto or perhaps an Autoharp (although the chords can’t be changed on this model).
We’re so glad that [Jared] spent the time to produce such a fine looking body for the instrument. The strings that would traditionally produce the sound on a harp have been replaced with laser diodes shining at Cadmium Sulfide photo resistors. When a beam of light is broken, an Arduino detects the change via the CdS cell and plays a sound through an Altec Lansing speaker inside of the case.
Unfortunately there’s no video available but we’re pretty sure it makes a “pew-pew” sound. There is a link to download the source code but it points to the overview page instead of downloadable code. From the fritzing diagram the CdS cells are part of a voltage divider which provides digital logic to the Arduino. That should be pretty easy to replicate even without seeing [Jared's] code and we’re sure you can source other Arduino instrument projects for tips on wave shield or midi functionality.

Thanks to [Josh, Kyle, and Mike], it is now possible to wage (Nerf) war with an Arduino. The turret designed around it is capable of shooting 6 foam projectiles in close succession, between reloads. The faux weapon interfaces with a computer through the Arduino’s onboard serial link (via USB). Software on the PC sends commands to the Arduino, which then executes functions, such as panning, tilting, firing, and rotating the cylinder. The power for the firing itself comes from a 5 gal, 80 psi air compressor. The Java software on the host PC also does smarter things, like show streaming video from the turret’s webcam and even performs basic object tracking (with mixed success). All the code for building the brute is available on [Josh's] website.
…well not quite, but Victorian-styled nonetheless.
In the same vein as his previous creation, [Jake] decided to steampunk his new monitor. However, this time around, he managed to squeeze a full pc into the retro case. A custom aluminum chassis had to be designed and safely house the disk drives and motherboard behind the monitor. Since the 350W PSU was a bit too clunky to mount behind the screen, [Jake] rebuilt the base of the unit around it. The P4, 250GB SATA hard drive, and gold painted cooling fan allow the machine to run Kubuntu “Gusty Gibbon” smoothly. Coupled with a typewriter-inspired keyboard, [Jake's] got a cutting edge antique setup.
[Fun3] wasn’t satisfied with current methods for duplicating Philips Ambilight. He wanted a completely plug and play solution without soldering so he could expand upon it in the future. This meant Arduino, ShiftBright, and (it pains us to say this) pre-made cables. Some of you are cringing at the thought of no real ‘work’ being necessary, but remember, now this is much easier for your “I can’t change the VCRs clock” aunt to set up and enjoy. Plus it’s quick, easy, and most importantly – clean, something a lot of hackers have a problem with.
We’ve seen the Arduino board in charge of some pretty unique tasks in the past. Harvesting locally grown soybeans was not one of them.
[Lance] rigged this beast up in order to automate the monotonous task of driving up and down the vast soybean fields of Iowa. The 15 ton farm combine’s hydraulic steering pump is at the mercy of a team of gadgets, including a GPS, Windows 7 PC, and the omnipresent Duemilanove (which acts as the output card, connecting the PC to the pump). So far, it is reported to be doing a great job, straying only about an inch and a half from its desired, GPS-programmed, path. Even if the Arduino decides to go totally berserk and drive the combine off course, speeding around at 5mph makes it pretty avoidable. A supervisor is also in the cabin at all times, looking out for errors. [Lance] eventually hopes to offload all steering-related calculations to the ATmega328P onboard.
Commenters are welcome to share heavier-duty uses for the Arduino (if they exist).
