Project:

A video transmitting helmet attached to a Motocross racer.

Description:

I've found combining two hobbies can generate an incredible amount of new interest. Amateur Television (ATV) introduces an exciting new perspective that may not have been seen before. So ATV and Motocross racing is a perfect match! Several of my coworkers are Motocross racers. They ride motorcycles on closed loop dirt tracks with hair pin, sweeper, and jump turns. There's bumps, straight-a-ways to gain ridiculous amounts of speed, and jumps over 70' long! Certainly this hobby isn't for the faint of heart but with an ATV system mounted on a riders helmet we can enjoy the action.


Some Technical Information:

The small ATV transmitter package consists of an 100 mw 1.2 GHz FM transmitter (1300MT) with rubber duck from PC Electronics, bullet camera (GM-200K-STD) from Resources UN-LTD, and 12 volt 600 mAh Nickel-Metal Hydride pack (GP-600 AAH) from E.H. Yost & Company mounted onto a Motocross helmet visor (32-3397) from Dennis Kirk Inc. The receiver end consists of a Bensat satellite receiver from PC Electronics, 2414LY 14 element loop yagi from Directive Systems, and TV/VCR combo.

Conclusion:

This project was easy to put together and worked very well the first time. The ATVers and Motocross racers both had a blast. The video was a P5 picture a majority of the time. I love it when a plan comes together!
