RGBike POV

FIR7XMRFVRRH5S0.MEDIUM (Custom)

[Hazard] is designing this open source POV system for bikes. With the recent release of Monkey Electric’s m464q, [Hazard] was inspired. He found the price tag of roughly $2,000 to be way too much though. He is designing his own and taking us along for the trip. He hasn’t quite reached the Monkey Electric level of features, but he does have image display and simple animation. He encourages others to join him in improving the design. He notes that the image on the back side of the wheel is mirrored, so text would be backwards. Maybe he can pick some tips up from this old project.

Electric VW Mobile Photobooth

[Soren Coughlin-Glaser] runs a mobile photobooth in the Portland area. It’s built inside of an electric Volkswagen bus. The conversion to electric hasn’t been easy though. He’s spent most of the last few months rebuilding it after an electrical fire. Last fall he installed a 9 inch electric motor from Hi-Torque Electric after his smaller one blew up. We really like this project and look forward to seeing it back on the road… once he replaces his stripped transmission coupler.

Custom Motorcycle Display

[fibra] has been slowly building a custom controller for his motorcycle. It’s an automated chain oiling system that varies application based on RPM. The LCD can show wheel RPM, voltage, time, date, air, and engine temperature. A separate driver board has a MOSFET for controlling the oiling valve. The real gold here is the attention to detail. He built a one off circuit board. The case is laser cut acrylic that he then shaped. The box is molded smoothly into the original instrument cluster using epoxy. It’s excellent work that could be mistaken for a commercial product.

Disabling GM’s Manual Skip Shift

GM, in an effort to make their cars slightly more eco friendly, added a feature that puts your car in 4th gear when cruising along in 1st under certain conditions. This is apparently despised by many owners. I is despised so much, that you can buy a commercial product to disable it. That product costs between $20 and $40. Jalopnik has posted a simple solution to disable this feature for under $7 .  All you need is a replacement plug and a resistor. It’s really pretty simple.

OBD-II Automotive Data Logging

[Avi Aisenberg] sent us his final project for ece 4760.  His team built and OBD-II data interface. Even though OBD-II is an industry standard, each manufacturer has implemented it differently. This is where this project shines. They have built it to be capable of talking to any of them. Not only that, but it has a nice backlit LCD screen for diagnosing issues without having to go back to your computer and downloading the data. If you really don’t need all the bells and whistles, you can make one for roughly $15. They even have an OBD-II app for the iPhone.

GPS Logger With Wireless Trigger

[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.
