Hacking The Myvu Personal Video Player


[jongscx] picked up a Myvu personal media viewer and promptly began scheming about improvements. He decided he wanted to be able to watch any input on the device, not just an Ipod.

After some messing about with different inputs, he eventually calls Myvu to ask some questions. Surprisingly, he gets the engineer who designed the thing. The engineer turns out to be pretty helpful and is happy to help him hack the device. [jongscx] ends up finally getting it to work and posts the schematic for the world to see.

He says his hands are full with some other projects right now, but hopefully he’ll do an official write up with pictures of the final product soon.

[DrNathan] wrote in to note that [RetroPlayer] was responsible for much of the work as well as contacting the engineer.

[thanks, DrNathan]

Acer Aspire One Hard Drive Upgrade


As promised, [tnkgrl] has published part two of Acer Aspire One upgrade. In part one she added Bluetooth and more RAM. This time around she focuses on the storage. The subnotebook comes from the factory with an 8GB SSD. The flash based storage readily unplugs from a small ZIF connector. [tnkgrl] replaced it with a 60GB PATA Samsung drive salvaged from an iPod. It’s a 1.8inch disk and is only 5mm thick, so it can be tucked under the motherboard. Knowing its previous use, it should prove fairly resilient. You can view a video of the swap and more photos on Flickr.

Up next is part three, where she’ll add 3G support.

USB Wall Charger


[rbhays] did this sweet little hack back in 2006. He took a Motorola cellphone wall charger and modified it into a USB wall charger. He needed to charge his iPod, but misplaced the original charger. A replacement would have cost him $30. So he did what any respectable hacker would do, he cut up something else to make it work for him.

He had one sitting around that was equipped with a mini USB end. He checked it out and it was the perfect voltage. Some commenters below the project noted that their motorola charger had a higher voltage rating than his. Those would still work, but would require some extra steps to bring the voltage down.

After some careful soldering, and a bit of super glue, he’s left with a perfectly good wall charger. He can charge most things that only use the juice from the wall. Some things refuse to charge though, such as Zunes. There was another project by [Cvesey] that claims to charge Zunes as well. While wall chargers may be available fairly cheaply now, many of us have some of these cellphone chargers just sitting around. Now we have a use for them.

Nixie Tube VU Meter


[Daniel] sent in his Nixie tube VU meter. It uses 14 Russian IN-13 Nixie bar-graph tubes. He built a custom circuit to amplify, filter, smooth and feed a voltage divider to assign signal levels to segments and finally some high voltage transistors to drive the tubes. The circuit looks pretty big, but it’s repeated for each tube – so he worked hard to keep the cost down as much as possible. Now this just needs to live on the front of a massive tube amplifier.

IPod Laser Pointer


If you thought there wasn’t anything else to shove on the end of your iPod, [Alex] is here to set you straight. He used the DC power that’s available on the iPod’s dock to drive a cheap laser pointer. It’s pretty easy to do – just get a dock connector (sparkfun has em) and add a laser pointer module. If you’d rather access everything else, check out the super dock I put together a while back. Hit the read link if you’d rather see the picture in color.

Upgrade Your In-ear Headphones


I’m a fan of my Etymotic er6i (which have mysteriously vanished…) headphones, so this simple hack caught my eye. [James C] sent in this simple method of upgrading the more affordable apple in ear headphones. The idea is simple, use a small hole punch to cut out the center of some cheap foam earplugs. Then replace the soft surrounds on the headphones with them. I’m guessing that this trick would work for quite a few in ear headphones that I’ve seen lately.
