This neat accelerometer controlled marble maze adds a level of fun to retrieving a gum ball. You have to first navigate the maze using a controller that has a dual axis accelerometer in it to control the angle of the platform. Though that does look like a wii accessory, there is no wiimote in there. Only after you have completed it will the gum ball machine dispense the candy. [Dan] constructed everything himself, which might explain the lack of “pits” for the marble to fall into in the maze.
More details on the build and source code are available on his page.
We stumbled onto one of [Nik Melton]’s projects, an Omni-car. It is omnidirectional, meaning it can go any direction at any time without having to turn. The body was designed by him, then printed with a 3D printer. The control scheme is what interests us though. He has found a simple way to wire it to get the job done. Sure you can see that it suffers from some pretty bad “drift” when trying to go in a straight line, but overall, we think he pulled it off well.
You might want to take a few moments to look around his project page. This guy has done a bunch of fun stuff like delta robots, strange hybrid wheel/leg robots, tesla coils, and arm mounted flamethrowers. Judging by the videos, he’s pretty young too. We think his guy has a bright future ahead of him.
[Scott Holden] went all out this year and built an amazing Tauntaun costume. The Tauntaun from Star Wars was massive, standing 8 feet tall, and usually carrying a rider. [Scott] wanted to make it the correct size, and ultimately pulled it off. He had to build custom stilts to get the leg angle correct as drywall stilts were too straight. The rest is mainly pvc and fur. We think he did a fantastic job on this. The effect is quite nice, and we can imagine that in person it is even better.
Take note at the bottom of page 3. Apparently, he got pinned in the costume in his workshop and almost had to spend the night on the floor in the costume. That’s pretty wild, at least he was warm.
Introducing the Thingamagoop2! Remember that awkward looking box with two LEDacles sticking out and a bunch of strange buttons and knobs that with some circuit bending synthesized different sounds that kept your neighbor up for hours on end? Well now its back! Smaller and one less LEDacle, but jam-packed with more features – like our personal favorite: the ability to program it via Arduino. Check out a video of the ‘music’ after the break. Read the rest of this entry »
[Aki] wanted to do some stationary cycling to get in shape. Unfortunately, his stationary cycle is located in his garage which doesn’t supply much inspiration or amusement. His solution was to build a VR rig so that he could ride around inside google street view. He has rigged a simple sensor to his wheel to determine his speed and he’s using a vuzix VR 920 as a display and orientation sensor. While he notes that it isn’t perfect, or even reliable, we think it is pretty cool. He can go sight-seeing, while getting in shape from his own garage. We have to wonder if he gets a headache after a while though.
These days, HTPCs are becoming more and more common, however controlling the content elegantly can be a painfully annoying problem. Roteno Labs have come up with a wonderful solution they call the RFiDJ. Similar to the RFID phone we covered earlier, they used a set of picture frame coasters and mounted descriptive pictures as well as unique RFID tags in each one. When a coaster is placed in the sensor area the server begins streaming that particular selection, including local news, This Week in Tech podcast, and other specific albums. Roteno Labs even managed to include a “shuffle” tag which would play content randomly out of a library. The end result is very well put together, excellently documented, and there is even a working video after the break.
Ever sat down from a long day of hacking and thought to yourself “I wish there was a cool video game out there made just for me. Better yet, made by me!” Today is your lucky day with the release of UDK – Unreal Development Kit.
In days of old, the only solution to satisfying your game creation desires was a cheap game making kit, or adding to the millions of Source mods. Epic has changed tables by now allowing anyone to use their engine (non-commercially of course) to create the game of their dreams; who knows, maybe even the next Unreal Tournament.
UDK is currently limited to PC, but plans are in the process for PS3 and Xbox360 development. For those who cant wait, we suggest checking out XNA. Whatever tools you use, ever made a cool game? Tell us in the comments!
We’re pretty sure Apple decided to implement an IR sensor in their Mac Mini line simply to mock the user. For those who are unaware, the built in sensor only works with the standard Apple Remote; unless you happen to have a programmable PDA or similar you’re SOL. An alternative solution would be to install a USB IR receiver. But then your beautiful Mac Mini is forced to sit alongside an ugly black box. Why not have the best of both worlds? [SqueeZe] wrote an (almost) entirely non invasive tutorial for placing a USB IR receiver inside his Mac Mini. Reminds us of a certain hack a while back, but the objective was to get the IR receiver outside of the unit rather than inside. Different people, different worlds.
[Pyrofer] sent in his stereoscopic game project and we are just giddy with excitement. He has hacked apart an old TomyTronic 3D handheld viewer and put new guts in. He’s using a PIC micro to push stereoscopic imagery to twin LCDs. He wrote all code from scratch including the 3d library, wii nunchuck driver, and LCD driver. This thing even has bluetooth so he can play multiplayer if he ever makes a second one. The whole unit is kept alive via a lithium polymer battery so you don’t have to worry about any cords other than the wii nunchuck. This thing is awesome, we would love to play with one. You can see a video after the break.
[Computergeek] made an Arduino Shield in order to use it as an Apple remote. We like the construction technique that he used; taking perf-board and soldering the circuit and using stripped wire to interface with the pin sockets on the Arduino. He’s written the code needed to function as an Apple Remote but this shield has a lot more potential. This is an excellent opportunity to delve into the different IR protocols out there and create a universal remote for all of your random devices. We’d also want to give it a try as a TV-B-Gone.
The parts are easy to find or salvage without putting in an order. We’re not certain about his design, he should probably have invited a resistor to the party the two IR LEDs are having.
