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!

[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.

[Thomas] promised nearly a year ago he would give the community code and schematics of how he made his LED Multi-touch panel, but we would have to wait for his next version first. Well its finally here, bigger and better then we could ever have imagined. His new version is organized as a 48 by 32 matrix of 1536 LEDs, but he’s gone further by placing it behind a stripped LCD to make a multi-touch display. It doesn’t seem nearly as fast or accurate as the original, but potentially could be more portable than ones we’ve seen before. And yes, this time around he included how his LED matrix is made.
[Vlad-Andre] used some of his free time to build an alti-variometer. He does some para-gliding near restricted air space and wanted a backup altitude warning that would help keep him below the mandated altitude. His solution uses the SparkFun Weather Board in conjunction with their BlueSMiRF dongle to measure altitude and transmit it via Bluetooth. From there, he wrote a program to grab the transmitted data with his cell phone and display the information. His application also has the ability to set altitude warnings and log changes over time.
Using this system he is able to get altitude data with 3.5 inch accuracy. Because the capture application is written in Java it should be easy enough to make this work on other cell phone models. The project is clean and works well but we estimate the cost of the parts to be between $250-300, making it out of reach for those who don’t have a specific need for these types of measurements. This is especially true for paragliders who have much less expensive options available to them.

[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].
[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]
Ever wish your iPod touch or older generation iPhone had GPS capability? Now it can by using a Bluetooth GPS module along with the roqyGPS app.
In April we saw a pretty creative way to add GPS to an iPod by using a homebrew accessory. The new app is a better solution because it utilizes the larger screen and more functional UI of the iPod touch. We’re glad to see this come along because we’d rather not upgrade to the iPhone 3G just to get GPS support. roqyGPS has a fairly long supported hardware list, which should make it relatively inexpensive to pick up a GPS module either on sale or second-hand.
We’ve got a video of the release candidate after the break. As always, we’d like to hear from anyone already using this so please leave your thoughts in the comments.
