Excellent idea.  Thanks, 

But I think I am going to get on e-bay and pick up a proper supply.  I agree
with the sentiment of the list.

The power requirements specified in the 910H manual are 13.8 VDC +/- 15%, 
which is 15.9 V on the high side.  I would not feel comfortable running mine

at that level, however.  I would suggest putting a couple of 100A diodes in 
series with the + side of the power lead to drop it down closer to 13.8.... 
(2 would drop it to about 14.5, which is close to what you might encounter 
in a car with the engine running)
