Pressure Sensitive Keyboard

The Applied Sciences group in Microsoft Hardware have come up with an interesting tool. This is a pressure sensitive keyboard. Our minds went strait to gaming, as theirs did too apparently. They show how this could give you more control in your games based on how hard you push the button. Remember the first time you got to use an analog stick, it sure is hard to go back to a D-pad. We want to know when we’ll get to play with these cool toys made by Microsoft.

Tiny Bluetooth Teardown

The folks at SparkFun were startled by how small USB bluetooth adapters had become so they split one open. They noted a few interesting design features. It has a small folded trace antenna on the board edge. The metal USB housing acts as the RF shield. The bluetooth IC is an AS3620QA. Now we wonder what those tiny Buffalo drives look like inside.

Droplet

[Andrew Rapp] sent in this project called Droplet. He’s been doing work with Xbees and Arduinos together and built this little toy. He describes it as “sort of like a Chumby”. It has built in services for Twitter, Google Calendar, News, Gmail, etc.  You can download the full source code and plans on his site. His next planned revisions include possibly running it from a sheevaplug, making a nice case for it, and utilizing the unused pins of the arduino.

CPU Tachometer

Recently, analog displays have come back in vogue. This is partially due to the common steam punk theme that is popular right now. [Cristiano] has done an analog display, but instead of brass and polished wood, he’s gone automotive themed (Internet Archive Cache) with it. He purchased a cheap tachometer from ebay.  A circuit had to be designed to give the tach the signals needed for it to operate, and you can download the schematic from his site. As you can see in the video above, it works well. We think that “shift” light might get annoying pretty quickly.

Tangible Holograms

As you watch that video, you’ll probably find yourself wondering several things about the tangible hologram project. Why haven’t we seen these simple hologram setups used more often? Where did that cool air puff system come from and why haven’t we seen more on that?  When will this be integrated into the latest Xbox/PS3/Wii? We don’t know the answers to those questions, but we would really love to play with this in person to see how convincing it is.

Defcon Status At A Hosting Company

defcon

[Aaron] has been working at iweb hosting for about 5 years. When he started, the number of servers was small enough that managing them was fairly painless and could be done by just manually verifying that everything was operational. As the number of servers grew, this task became more and more difficult. They employed various methods of tracking problems, but found them all lacking in one way or another. They got an idea to build a Defcon status page based on all of the information collected about their server status. The page was built and all rejoiced. As with most projects, they just couldn’t leave it alone. Next, they built an android app to be able to see the defcon status from their phones. As cool as that was, they felt they needed to have yet another way to keep track. They What you see above is the prototype for the office defcon status display. It is extremely simple, using an Arduino (yes, we know, massive overkill) to receive status updates to change the display number. [Aaron] says that right now it is a mess, and you have to shield it from the light with your hands to see it, but it works. What should the next step be? A giant Alpha Numeric LED indicator? A nixie tube?

Lazy Man’s USB RFID Reader

[Don] had some Serial RFID readers that he needed to work and be powered by USB. He went out and purchased a simple serial to USB converter, but was left with the problem of the operating voltage. He supplies the schematics on his site for his solution. Basically he gutted the converter and integrated it all with the appropriate voltage broken out. The final project is nice, using the serial to USB convert as the project box and even including a nice LED to show when an RFID tag has been read.
