According to Hitchins and May in From
Lodestone to Gyro-Compass
(2nd edn 1955, p. 84-5), the first suggestion of a liquid-damped
compass came from a German called Ingen Housz in 1779. The earliest
example they found of one actually being tried was a liquid compass
made by Gabriel Wright of London for Capt. Sir William Chaloner Burnaby
in 1781. The earliest patent known was taken out by a watchmaker,
Francis Crow of Faversham in Kent, in 1813 (no. 3644), Source: Gloria Clifton, RGM.

In 1890 Lieutenant Joseph Peichl of the Austrian Navy proposed a transmitting magnetic compass
system that required fewer wires than F. Jenkin's design. A contact on
the compass card remained between two contacts in the bowl, and when it
touched either energized a follow-up motor, which drove round the bowl
until the contacts were again parted. While the bowl was rotating two
wires were supplied with current alternately and, energizing two
electro-magnets in turn, operated a repeater by a pawl-and-ratchet

remote-controlled model submarines
Helmut Huhn and Heinrich Kistenich have developed a batch of
remote-controlled model submarines steered by means of a compass
needle. The inventors placed a cheap pocket compass' magnetic needle
inside a voltmeter's coil frame rotated by means of a remote-controlled
servo-motor to set the ship's course. The needle's rotation is limited
by two lateral stops. Located above the needle's north end, an LED
casts its shadow onto two phototransistors (s. pics below). As long as
the latters receive a differential amount of light they activate the
ship's propellers until the hull is on course and the needle exactly
between the phototransistors.
