[simpits-tech] Altimeter mod

[Craig Rochester]

I've modified a Kolisman altimeter to operate on compressed air.  I've reversed the operation by puncturing
the internal bellows, relieving the vacuum, and then resealing the bellows with solder.  Now the altitude
value indicated by the needles decrease with increasing pressure.

I've hooked the altimeter to an I/P(electronic pressure regulator).  By varying the voltage to the I/P I can
control the altitude reading.  Here's a short avi movie:
