Problem:
Using the BMR co-pilot shelf, I mounted
my video camera in the middle of the
shelf since my GPS Nav-II is using the factory BMW mount. My Problem: I
purchased a Canon ZR700 Digital Camcorder that is small and light weight since
my previous camera was much larger, heavier and analog. The Canon ZR700 works
great and includes an option to record in wide screen, which for motorcycle
videos is a great option. Unlike my older camera, my new Canon only provides 60
minutes of battery power at the most. This caused problems during my first test
ride since I had to continually turn the camera off and on to save power. This
action was annoying and caused me to miss some shots waiting on the camera to
power on. To eliminate this problem I designed and made my own DC power supply
for less than $11. A third party 12V power supply was $79 and very bulky not to
mention would look stupid hanging on my bike.
My Solution:
My solution is very simple. I purchased a voltage regulator (LM78xx voltage
regulator) that reduces 12 volts to 8 volts (required by the camera) and
maintains that voltage level to the camera. This part was a whopping $0.59 along
with the small din plug at $0.69. The most expensive part was the cigarette
lighter adapter at $7.45. This solution allows me to leave the camera on all day
when riding without worrying about the battery dying. Maintaining the voltage at
7.5 volts also allows the camera to continue charging if needed.

Individual parts prior to assemply. I choose low voltage wire to
keep the adatper harness small and thin.
