[Jonathan] sent us a pretty in-depth writeup of his car computer system. This isn’t your typical quasi navigation/media system as you would usually expect with this title. What he has done is made a remotely accessible monitoring computer that can tell him everything from engine data to physical location of the car on a google map. He can start, stop, lock, and unlock the car as well, as long as the car is within a 3g network. This is pretty impressive and we see tons of uses for this, from analyzing your own data to keeping an eye on those pesky teenagers when they borrow the car.

Bender Keg Cooler

December 11, 2009 by Caleb Kraft 5 Comments

What? Another Bender project? This almost went in the trash since it looks so much like the bender brewer from earlier this week, we thought it was the same tip. This isn’t a brewer though. This is a keg cooler, made to look like Bender. You can follow the build process to see exactly how they constructed it. They did a great job, the tap is in his cigar, and the keg resides in his body. Fantastic job guys, now you need some Benderbrau to dispense.

Perspective Tracking With Only A Web Cam

[Johhny chung Lee], eat your heart out. Check out what these guys are doing with face tracking and immersive 3d as their final project in class. They’re using a singe camera and an FPGA to produce the demo you see in the video. Facial tracking is done by skin color, so that might have some issues in some environments, but being able to have perspective shift with you, without rigging up some more hardware is fantastic.

We realize that this is completely different that what [Johnny] is doing. We love [Johnny]’s work and think it is ground breaking to be able to pull this stuff off with a cheap game controller. We just couldn’t help but draw the parallel from the end result.

[thanks Bruce]

Homebrew Kodachrome

What do you do if you can’t find the film that your camera uses? The answer seems pretty simple, you just make it yourself. Making film is not a simple task. There are multiple stages involved and it all has to be done in complete darkness. This project is causing a bit of stir in its respective communities. Though not completely finished yet, it is already an impressive piece. Everyone is waiting eagerly for it to be completed. You can find a few of the discussion groups linked from the flickr page.

Overly Complicated Gas Guage

December 8, 2009 by Caleb Kraft 39 Comments

While this is most likely overkill for a gas gauge, we do thank [VadimS] for sharing the information. He shows us how to build a capacitive liquid sensor using an Arduino, some foil and some wire. He’s basically detecting the difference in capacitance between the foil sheets. As he gets more water in the bottle, the capacitance goes up. At least we think thats what is going on. He has included the source code for the Arduino, both for handling the sensor and running the LCD display shown in the picture above. When completed, this will be used in his dune buggy for a gas gauge.

LEDboy Super Pixel Brothers

We really love this version of super mario brothers that [Brad] is putting together. It is played on an 8×8 RGB LED screen, powered by a pic microprocessor. There aren’t many details on the construction or code yet, but we expect he’ll publish it soon. We’re guessing it is very similar to his other 8×8 game system. If you really want to get a jump start, he has published some great tutorials on working with pic microprocessors.

Pranav Mistry’s Cool Input Devices

This new video about [Pranav Mistry’s] SixthSense project doesn’t bring us much that we haven’t seen before. At least, not on that project. What really caught our eye was the device he shows off at the beginning of the video. Using two old ball mice, he constructed a grip style input device. It is simple and elegant and we can definitely see using this in future hacks. Not only is it cheap and apparently effective, it seems as though it could be constructed in a very short amount of time. all you need are the wheels that spin when the ball moves, 4 springs and some string. Why didn’t we think of that?

[thanks Sean]
