[Judyofthewoods] has hacked together this rollerbar mouse. We’ve heard people talk about these in a positive way, going on about how comfortable they are. We haven’t really experimented with one much to verify. This one looks surprisingly nice considering it is made from scrap. The image above is showing it without the cover that hides the hot glue and optical sensor. There isn’t much of a writeup, but as you can see from the picture, there isn’t much necessity for one either. She seems to have done a great job stating that it is fairly smooth with only minor jittering.

Ok hackers, it is time to show what you are made of. [Michael] has issued a challenge. He is willing to pay for hacked together science tools that meet some accuracy and price requirements. You could win money for doing what most of you are already doing. He needs a few specific things, so go to his site to see what he’s looking for. The goal here is to bring scientific equipment down to a price level that allows a broader audience to access it. Come on guys, it’s for science!

Nes Controller Storage With Security

[Joven] wrote in to show us his unique NES controller mod. He initially thought of just putting some flash storage in his controller like so many others. Then he got the idea to a security feature. You must first enter a code to access the memory. What code? Yes, that one. He chose the Konami code. As he notes, this may not be the wisest choice for security purposes, but it sure is cool. At least it isn’t controlling something that really would require security, like his door. You can see a video describing the project after the break.

32GB Solid State Zune Upgrade

[Andrew] wrote in to show us how he upgraded a broken Zune to solid state. He had one that was giving the Error code 5 when it booted. This means the hard drive is bad. He was able to find a compatible solid state 32Gb drive that, with a little bit of case modification, he made fit. Everything fit back into the Zune and looked completely stock. This was all done for less than $130. He seems pretty proud of getting a 32GB Zune for $150, and we don’t think that’s too big of a deal. We found a bunch of them on eBay for under $100. He even states that he doesn’t see any performance or battery life improvements. So why do we post this? Well, we like to see stuff split open and we actually like the idea of a no-moving-parts mp3 player. We’re hard on our electronics and the thought of that platter getting jarred over and over and over and over really bothers us. Great job [Andrew].

IR Air Conditioner Timer

installed (Custom)

[Tom] has an office job in China. His office is cooled by a small single room air conditioner. In an effort to make his office a little more comfortable, he built this IR timer unit. It cools his office down before he gets there so he doesn’t have to wait for it in the morning. He started by decoding the IR signal from the remote for the unit. He then built this ATiny13 based remote. He notes that the internal clock of this thing isn’t that accurate. power cycling it every day seems to help. It is also pretty cool that he built the unit to not only send the cooling code, but he can switch it to the heating code for the winter.

[thanks Mario]

Portable, Digital Stereoscopic Image Viewer

October 9, 2009 by Caleb Kraft 6 Comments

FSI6C3BFZWXORMT.MEDIUM [madaeon] couldn’t find a digital viewer for his stereoscopic 3D images. He felt that he could probably build one, so he did. He found two identical digital picture frames and made a custom rig to hold the two frames. The method he is using involves polarized lenses, so you do have to put glasses on to see it. Being polarized though, you get full color, like modern 3D movies. We think it would be even nicer to see them without glasses, but some people have a really hard time with this style of 3d image.

Nokia: Destroying Phones For Fun And Profit

No matter how grumpy you are in the morning, this video should make you smile. This is one of the jobs many of us dream of. Take a tour around Nokia’s product testing facility with Engadget. Watch in the video as phones are squashed, pinched, smacked, baked, shaken, dialed, slid, opened, and closed repeatedly. Sure, we don’t get to see any of them obliterated, but it sure is fun to see those machines at work. Each one of these tests will be run until the phones eventually come apart or cease to function. Too bad they didn’t show us that part of it.
