When an unsuspecting person walks up to [Rob Ray’s] ATM machine, they are greeted with a surprise that doesn’t involve giving them their money. When they insert their card, the video above plays followed by a game where you control a beaver trying to save money during a recession. Surprisingly, people usually found it humorous and didn’t immediately freak out that their card was in a machine that wasn’t their ATM. His site has all kinds of pictures of various users as well as the construction of the project.

Phototransistor Multitouch With A Twist

multitouch

[Alex] sent us this project he’s working on where he’s building a phototransistor based multitouch input system. Though many people have built systems with phototransistors, most of them are quite large and very sensitive light and dark variances. [Alex] has done some fancy background subtraction through software. He believes his is the first to do this. As you can see in the video after the break, it seems impervious to the lamp he is moving around, and still fairly sensitive to his hand. We’re curious to see where he takes this one.

Remote-Exploit.org is releasing Keykeriki, a wireless keyboard sniffer. The project is both open source hardware and software. you can download the files on their site. Right now you can’t get a pre made board, but they plan on releasing one soon. The system can be upgraded with “backpacks” or add on modules. One of these is going to be an LCD that displays the keystrokes of the keyboard you are sniffing. Another is supposed to serve as an interface to your iPhone. Right now it has the ability to decode Microsoft wireless keyboards, but the Logitech pieces should be added soon.

glove

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.

Evil Mad Scientist Laboratories has released the 2313 target board. A business card sized development board for working with ATTiny 2313 microprocessors. We saw them at the Maker Faire, and thought they looked familiar. You may recognize them due to their similarity to the Atmegaxx8 family board. As usual, this is released as creative commons and source files are available on their site.

Electronic Stethoscope

[Vik] sent in this simple little project. He purchased a $3 spy ear, a simple 3 transistor amplifier, and attached a stethoscope end. Little modification was necessary, mainly just scraping a bit more space in the microphone tube. The end result is a super cheap electronic stethascope that can be hooked to a computer or other speakers for multiple people to listen to.

pikachu_goggle1 (Custom)

These nifty looking goggles are actually an instrument. The guts of a pikachu doll have been splayed and mounted to the goggles. The controller is an external box that allows you to make all kinds of changes to the pitch and sample section. You can see a video of it after the break. We don’t really find this to be great music, but find watching the guy fairly amusing.
