Look at this awesome glove. This awesome glove is used to control tetris. Yes, you read that right, it controls tetris. This was a final project at Cornell in the summer of 2008. They built this glove to do gesture controlled tetris. With all the announcements of the PS3 motion device and Microsoft’s project Natal, it’s nice to look back to our very recent past and see some alternative user input. These people are using accellerometer data only, sent to the computer wirelessly.

[phreakmonkey] got his hands on a great piece of old tech. It’s a 1964 Livermore Data Systems Model A Acoustic Coupler Modem. He recieved it in 1989 and recently decided to see if it would actually work. It took some digging to find a proper D25 adapter and even then the original serial adapter wasn’t working because the oscillator depends on the serial voltage. He dials in and connects at 300baud. Then logs into a remote system and fires up lynx to load Wikipedia. Lucky for [phreakmonkey] they managed to decide on a modulation standard in 1962. It’s still amazing to see this machine working 45 years later. He’d love to hear from you if you’ve used a similar device.

No one will ever accuse us of being Windows fanboys; we’re certainly fans of netbooks though (or anything cheap enough that we don’t care if we accidentally burn a hole through it). We’ve heard from quite a few friends that Windows 7 is actually an excellent operating system to run on a netbook and is a dream compared to XP. Gizmodo has compiled a guide to getting the release candidate on your lightweight machine. It’s available now and will work for free for a year. The image is 2.36GB which you need to dd onto a USB device. They recommend at least an 8GB drive, but anything smaller than 16GB and you’ll have to use Window’s compact utility to save space. Other than these space considerations, the install appears to be easy. Let us know about your experiences using Windows 7 on your netbook.
Got an IBM PCjr laying around? Why not turn it into a twitter browsing machine? [Alex Grant] did this for the Rochester Institute of Technology’s Creativity and Innovation festival. You can enter search terms into the Twittjr and it will display the top 3 results from twitter. Leave it alone for a minute and it will refresh on its own. To make this happen, the Twittjr is connecting to another computer that is utilizing the twitter API to make the searches. The results are then pushed back to the Twittjr for display. All of this is done via the original modem. While [Alex] takes a moment to explain what twitter is, we feel it might be better to explain what a modem is. You see, back when the PCjr was new, we really did communicate via an analog signal over the phone lines at roughly 300 baud.

This project is particularly amusing. It doesn’t have a whole lot of practical use, but it makes up for it in style. They have an SD card with Wikipedia from 2003 downloaded to it. This is accessed with a Parallax propeller microcontroller based system and displayed on a small retro looking screen. We like it. We don’t think we would ever actually use it, but we would definitely keep it around.

[Justin] sent in his 1st place winning project from Northeastern’s Electrical Engineering Senior Design Capstone. It’s an interface that uses electrostatics to detect your hand position above it. As you can see in the video, it has decent resolution and can detect position on all 3 axes. When they uncover it, you can see the sensors arranged in a grid. They point out that each sensor isn’t just like a button, but rather detects a range of motion. They are using a pic 18×4550 to handle the sensors, which then communicates to the PC via USB. This could be pretty useful for musical performances as well as an alternative interface for people who can’t use a mouse.EO
Here’s an interesting bit of research to come out of Microsoft and UCSD. The Somniloquy project is a new type of network interface. It’s a USB device that allows a computer to continue network communications after being put to sleep. By offloading these tasks, machines that would normally stay awake for RDP and file transfers are only powered up when absolutely necessary. The device uses a Gumstix board like the one used in the Tor hardware adapter. The device pictured above has two USB interfaces, but the second is just for debugging and not needed for proper operation. The board runs BSD and creates a USBNet bridge to the Vista host. When the host daemon detects the computer going to sleep, it hands off active communication to the gumstix. They developed “stub” applications to handle the various types of communication. For downloads, they used wget to download only the portion of the data that was still left. For bittorrent, they customized the command line client ctorrent to manage the download. Both programs wake up the PC upon completion and transfer the file off of the SD card.
