Fancy LED Invitations

INVITE

We would be thrilled to get something like this in the mail. What you are looking at is the inside of probably the coolest invitation ever to be mailed. This LED array was enclosed in a mirrored box so all you could see were the lit LEDs. This was then inserted into a hole all the way through a catalog. You’ll have to see the pictures on their site to get the full effect. Only 40 of these were sent out, so we probably won’t get a chance to play with one ourselves. They mentioned that the first prototype was soldered by hand, just to make sure everything worked.

GPS Logger With Wireless Trigger

gpslog

[Matthew] sent us his group’s final project, where they built a nice GPS logging system. Not only can it simply log the GPS coordinates on a predetermined interval, it can also be triggered to make an entry by a wireless device. In this example, they use a camera. This allows them to then upload all the GPS information and pictures to places like Google Earth.

They are using an ATmega644, with an LCD, SD card, and GPS unit. They had to do a little hacking on their camera to add the wireless transmitter, which triggers the logger. You can see not only the cost break down and source code for the project, but also a map with lots of geotagged photos. This is the kind of thing we can almost see as a standard item in the future.

Home Made R/C System

[dunk] sent his home made Radio Control system. It is constructed from a Playstation 2 controller, an Atmega 2561, microcontroller, some RF modules and various servos and motors. It seems to work pretty well. You can get all the schematics and source code on his site. Several people have submitted a similar project which involves an iPhone and a helicopter, but that one is a bit dubious, mainly due to it’s lack of detail.

Nove Bit: A 9 Bit Memory Recorder

Nove Bit looks like a pretty cool toy. You press sequences into the 9 buttons and it plays them back. We think it would be cool to play with. The artist [Nick Hardeman] states that the project is to allow you to save memories in 9 bit configuration instead of the traditional 8 bit computer method. Why don’t artists just say they did it because it looks cool? We want one of these, but We really think that recording our memories has nothing to do with it. You can see a video of it working after the break.

Roomba With Dustpan Style Grasper

Remember El-E, the service robot that would retrieve things that you spotted with a laser? The creators of El-E are doing research into other methods of making assistance robots. Their latest contraption is an iRobot Create, basically a Roomba, with a custom grasping hand. Instead of complex multi DOF assemblies, they have made something that works on the same principle as a dustpan. It has a thin wedge and a sweeping arm that loads items onto it. As you can see in the video, it is quite effective.

Fart Intensity Detector

farts

When we ran the story about the office chair that twittered your flatulent activity, many people commented on the fact that it had no method of determining intensity. Well, here’s the solution to that problem(is this really a problem?). These students built a fart intensity detector for their final project in ece 476. It measures the sound and temperature, as well as the composition of each fart. They really added some bells and whistles on this project. Not only will it display your statistics on and LCD screen after a reading, it will beep and, if your fart was intense enough, blow it away with a little fan. You even have the option of playing back the audio recording of your most recent glory.

WhereAVR APRS Tracker

WhereAVR_Board

We posted a story about someone doing some APRS tracking recently. This is old news to some, but new fresh stuff for others. If you want to build your own tracker, here’s a great writeup on one. The WhereAVR is low cost, low power and has plenty of I/O. With all of the schematics and PCB files available on his site, you should be able to get one working in quickly. He does need a little help building a nice simple configuration tool to work in windows, anyone want to volunteer?
