You could just run it off of 12 volts.  it will make half the heat it had at
24 volts.  some pitot's get pretty hot, yours might make enough to melt some
of the ice.

Another thought, some pitot's have replaceable elements.  Check and make
sure yours can or cannot.

I've seen Chuck's pitot, looks like it is gold plated to match his paint, it
would be a shame to scrap it.

| Looking for any ideas out there.  My Velo has a 12v system but a 24v
pitot,
| which was installed prior to my involvement.  Is there any way of jumping
| from 12v to 24v to drive the pitot, which draws a few amps.  The reverse,
| 24v to 12v, seems to be able to be done quite easily.  But going from 21v
to
| 24v seem problematic and I haven't discovered any great solutions.
|
| A second avenue of exploration is this Velo is equipped with two (2), 12v
| batteries.  Is there a way of taking the 24v from the two batteries
without
| having a totally jerry-rigged system whose failure could potentially make
| both batteries inop?  The dual battery, even though I've never had to
switch
| to the second unit, is a degree of redundancy that I would not like to
| compromise.
|
| Why not change out the pitot?  Well, the previous one was plated and
fitted
| for the plane, right on the pointy end of the plane and I kind of like it.
| Changing it out with a 12v unit would be a last resort.  Ideas?
