RGBike POV

[Hazard] wanted a full color POV display for his bike wheel. Adafruit’s SpokePOV is single color and Monkeylectric’s original version didn’t display images. He also balked at the cost and decided to manufacture his own version. It uses 16 RGB LEDs on a single layer board he manufactured himself. It’s an entirely through-hole design to make assembly easy. It uses a hall effect sensor to synchronize the image display. The two main components are an ATmega328p microcontroller, which should make it Arduino compatible, and a TLC5940 PWM LED driver. It’s a very well documented build and certainly a good looking effect.

Bluetooth Motorcycle Control Panel With Arduino

[Bill2009] has made some nice progress on a control panel for his motorcycle over at the arduino.cc forums.  It can show speed, tachometer readings for the wheel and engine, as well as indicate the current gear. He reads the square wave coming off of his tachometer input and pulses from a reed switch mounted on the wheel to calculate all this. To top it all off he can monitor the data via a Bluetooth module attached to the board, which is much better than trying to balance a laptop on your knees while cruising down the highway.  He is working on getting the size down so that he can mount the whole assembly inside of his motorcycle. He also plans to add new software features like wind resistance calculations and0 to 60mph timing.

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.
