Project Description


The purpose of our project is to design a wireless heads up display (HUD) for a motorcycle helmet that will display the rider's speed and engine rotations per minute (tachometer). A helmet with these capabilities could drastically improve rider safety, as the rider's eyes would never need to leave the road. This helmet could be used for everyday street riding, or even at a track in competitive races. To achieve this, we need a way to get the desired information from the motorcycle, transmit and receive this wirelessly, and figure out a way to display this information on the helmet visor. The display would need to be easy for the rider to see and read, yet still be non-intrusive, so that it is not a distraction to the rider.
We will try and design the HUD to be on the visor using LEDs or a similar type of low power low weight device. The rider's gear would be displayed on the left side of the helmet visor, while the speed would be displayed on the right. The tachometer would not be displayed as a number, but rather as a group of colored LEDs. Idle/low RPM would be displayed in green, starting on the top left of the visor. As the RPMs rise, more green LEDs would light up across the top of the visor. When the RPMs reach around 70% of the maximum, orange LEDs would begin to light up. These orange LEDs would be displayed from 70-89% of the motorcycle's total possible engine speed. For 90% and above, red LEDs would be used to indicate that the RPM is nearing the rev limiter.
The transmitter for all of this information would be powered off the motorcycle's 12V battery. A battery stored in the helmet would power the receiver and HUD. We are debating whether or not to try and design this as a rechargeable and/or solar power source or other portable renewable sources.
