No stranger to AMSAT publications, Gabe Emerson, KL1FI, publisher of
saveitforparts.com is at it again. This month Gabe has posted a 24-minute
video on how to use parts from an old security pan-tilt camera mount to
build an az-el satellite rotator.
The rotator motors are controlled by software based on the Australian
School Amateur Radio Club Network (SARKNET) Rotator Mark I Arduino code.
The software can be run on either an Arduino device or on a PC laptop.
Gpredict is used in this example to track the satellites.
Gabe uses the rotator to steer a small dish but it looks strong enough to
handle a lightweight yagi such as an Arrow or Elk if suitably
counterweighted.
Even if you aren't interested in building this az-el rotator, Gabe's video
is a fascinating look at how an inventive mind and resourceful scrounger
can make something actually useful. Ham radio as it should be! More
