Twitter Brain Interface

April 20, 2009 by Eliot 36 Comments

Just in time for the influx of sedentary Oprah viewers, [Adam Wilson] built a brain interface that allows you to post Twitter messages. The electrode cap monitors the user’s brain functions to determine where they’re looking. The display slowly flashes each letter in the alphabet. The user focuses on the letter they want and when it flashes the cap can pick up the resulting impulse. It’s a long process and the average user can only do ten characters a minute i.e. 14 minutes to use all 140 characters in a Twitter post. It’s interesting research and shows how far we still need to go with neural interfaces. The researchers note that Twitter’s forced brevity levels the playing field between locked-in patients and normal users. A video of the device in use is available on the NITRO blog.

Space Invader Button

April 14, 2009 by Eliot 36 Comments

[Marcus] saw [Alex]’s 64 pixel project and decided it could be implemented in even less space. Pictured above is his Space Invader button with a bicolor LED matrix. The controller board is all SMD and piggybacked on the matrix. An ATmega164P drives the 24 pins via transistors. In addition to animation, the board can do LED sensing too. It’s a very clever project and [Marcus] has some notes about working with such tiny components. You can see a video of it below. Continue reading “Space Invader Button” →

Spatialized Umbrella

umbrella-1

Reader [Joe Saavedra] sent in his latest project: the spatialized umbrella. The base of each umbrella rib features an LED, speaker, and distance sensor. These are connected to an ATMega168 microcontroller running the Arduino environment. The IR sensor triggers a rain drop sound based on proximity. Shorter distances mean more droplets are played. The sounds are generated using a lookup table and the digital pins. You can see the demo video embedded below.

Using the Arduino environment without the associated board is part of another idea that [Joe] is working on. The MapDuino Project uses the standard Arduino hardware for programming, but then transfers the chip to a more barebones circuit in target project. They based their initial work on the ITP breadboard Arduino. Continue reading “Spatialized Umbrella” →

HAL Suit Going Into Production

When we compiled our list of real life power suits last May, the HAL suit was being pitched as a $1000 a month rental. Cyberdyne has changed their tune for the better recently. Teports suggest that the first 400 unit run of powered exoskeletons will sell for $4200, less than a Segway. The suit can increase the wearer’s strength ten-fold and will run continuously for nearly three hours.

Power Glove 20th Anniversary Edition

Using an original Power Glove, a bluetooth module, an Arduino, and an accelerometer, [Biphenyl] brought the system up to date. As you can see in the video after the break, the new version is wireless and much more useful in the games. Skip to 11 minutes in if you just want to see it in action. There’s a full writeup on Instructables if you want to build your own. We love the power glove and we can’t wait to see a more developed game for it. This beats the Power Glove Wiimote, hands down.

KanEye Tracking System Preview

[Tempt One] is a graffiti artist who has Lou Gehrig’s disease. He can no longer physically produce art, since his disease has taken his ability to control his arms. His friends, won’t let that be the end of it though. They’re building a visual tracking system to let him work by moving his eye. It seems like it would be very difficult to get any kind of a smooth curve out of eye movement, but the short demonstration video, which you can see after the break, does a decent job, at least for something this early in development. The source code isn’t released yet, but they do plan to do so. If you wanted to make your own, you could find some info in a past post of ours. We’re guessing they intend to use it with something along the lines of the laser tagging system.

Daft Punk Costumes

[derektroywest] has posted a detailed step by step breakdown of making a Daft Punk costume. They’ve done a great job, the overall look is very convincing. They include links to where to get each part as well as information on how they pulled it off. The helmets were inspired by the timelapse Daft Punk helmet build. As you can see in the video, they don’t have the entire visor made into a display, but the effect is quite nice, especially because it is multi color.
