![]() ![]() Thanks to Alex Simoes and Nan Zhao for starring in the concept video. Thanks to Joe Paradiso and his Location-Aware Tech class, for which this project was constructed. UPDATE: I'm ordering some Arduino FIO boards, XBee series 1 radios, and Parallax GPS modules for the next round. On the other hand, I think the zigboards are really cool and I'd like to contribute to the project if there's a need. It seems that it may be more straightforward to do this with some Arduino Xbees. I would ideally like to have helmet-based mobile transceivers, without base-stations, outputting proximity data that is visualized by some LEDs. I'm now struggling with deciding on next steps for my helmet project, especially as it pertains to the remaining time in the semester. To these questions, Brian explained that the Altoids tin is a completely different platform called Fish River Island (FRI) it's not just a compute module in a box. How did you de-couple the compute module from the carrier? Also, do you have any spare Atoms already encased in your altoids-like boxes? I'm trying to get a hold of some even smaller computers (Raspberry Pi) to run them.Ģ Questions about the Atom (answered later by Brian).ĭo you add a hard drive to it so that it won't need to boot from the USB stick every time? Brian explained that the networking protocol is still a work in progress.Īt any rate, the Mac Pro is too big to strap to a bike helmet! So I set up the Intel Atom to possibly run the Zigboards. Also, when I tried to connect the Zigboard to a USB wallwart, its green light starts blinking and it won't connect. However, the long USB cables don't provide enough slack to really change link quality index or energy detection when the Zigboards are moved around the room. That worked ok, though sometimes there were disconnection issues. Then I attached the Zigboards to the Mac with super long USB cables. I tested the Zigboards using this script, a simple adjustment of the python script on Brian's wiki. ![]() In earlier tests for this project, I tried working with "Zigboards," or zigbee boards with additional control, by Brian Mayton. It's a little spooky to be seeing my tracking visualized. It's sending its position every few minutes. I'm using a GPS data service called InstaMapper. I set up a quick app on my iPod touch to be tracked using its internal GPS module. To-Do: dealing with zero values (which are outputted seemingly randomly at all ranges) and perhaps decreasing frequency of processing. The sketch is also a little noisy at the moment. The sketch can be modified to map up to 200 meters (values of up to 200 from the XBee RSSI pin). Right now, this sketch maps about 5 meters to a 10-LED series (values of up to 50 from the XBee RSSI pin).

I used a couple of Series 1 Xbee radios combined with a couple of Arduino Fio boards. Click to play demo video A light gauge connected to an Arduino Fio.
