Electric engineer build's Thor's
weapon, Mjolnir which can only be
lifted by him
A replica of Thor's hammer Mjolnir
build by an electric engineer using
powerful electromagnets and a
fingerprint scanner
Only the ones who are worthy can
hold and use Thor's famous and
legendary hammer Mjolnir in Marvel
comics. For the ones who are not
worthy, which is almost everyone
except Thor and the odd someone
else occasionally (an useful loophole
for writers), Mjolnir just cannot be
lifted off the ground.
It is this thing that electrical engineer
Allen Pan, AKA Sufficiently
Advanced on YouTube, made a
decision to reproduce in his very own
take on a "working" Mjolnir.
He decided to use the strong magnets
to make the hammer immoveable, as
that was the best method. He filled a
microwave oven transformer
electromagnet that uses electricity to
produce a magnetic field inside the
head of his Mjolnir. This in turn
produces a strong magnetic pull,
which is so strong that when the
hammer is put on a metal surface, it
feels very heavy to lift.
The handle is attached to a capacitive
touch sensor, which in turn is
attached to an Arduino Pro Mini and
a solid state relay, which works as a
switching device. The electromagnets
switches on immediately when
someone grasps the handle, attaching
the hammer to the metal surface.
However, a fingerprint sensor that is
keyed to Pan's thumbprint can be
used to turn off the hammer. But the
magnets switches on when Pan holds
the hammer. Then it switches off
again when he moves his thumb over
the sensor, letting Pan to lift the
hammer.
Pan challenged unsuspecting
passersby on the streets of Venice
Beach, California to lift the hammer.
One must say it is quite an
impressive prank.
