4. SOLDER THE WIRE TO THE TUBE
Bend the top wire around the tube and downward.
Solder the wire onto the outside of the tube and
let it cool (Figure J).
After cooling, manually check the rotation of the
motor to make sure that the wire does not interfere
with the counterweight. If it does, push the wire
away with a pencil.
5. COMPLETE THE MODULE ASSEMBLY
Insert the spring, then the washer, and finally the
cross-pin, which holds everything in place. The
cross-pin can be made from a properly sized brad or
any type of sturdy metal, and cut and filed to length.
6. PREPARE THE SHARPIE PEN
Pull the Sharpie apart (Figure K). Discard the large
ink reservoir. With pliers, remove the writing point
from the nose (Figure L), and set the point aside.
With an i" drill bit, drill out the nose of the Sharpie
to a depth of around 1". Snip the writing point to
about ¼" long, and reinsert it into the Sharpie nose.
Now insert the vibrating module into the Sharpie
M
and snap the 2 ends together. Put the cap back on
(Figure M). When a magnet is drawn near the pen,
or vice versa, it will vibrate.
Neodymium magnets have the best power-to-size
ratios of all magnets, and can be concealed easily.
A drop of super glue can hold one under your hand,
and when you sweep it over the Telekinetic Pen, it’ll
set it off. The magnet can be peeled off afterward,
and any glue remnants will wear away.
NOTE: The Telekinetic Pen will be heavier than
a standard Sharpie, so plan accordingly.
Telekinetic Pen Kit: The Maker Store
( store.makezine.com) is offering a parts kit for this
project, including a cut-to-length brass tube, the
micro pager motor, reed switch, spring, washer,
and pin material.
