Project 10 Disco Ball
Build the circuit shown on the left by
placing all the parts with a black 1 next
to them on the board first. Then,
assemble parts marked with a 2.
Connect the two blue jumper wires to
the snaps on top of the disco motor
(DM). Install three (3) “AA” batteries
(not included) into the battery holder
(B3) if you have not done so already.
Place one of the disco covers on the
disco motor shaft. Note that both sides
of the support bar are “D-fit”.
Turn on the slide switch (S1) and watch the
show. Place in a dark room for best effects.
You can make the disco cover spin
more slowly in projects 83-87, 142,
and 200-202.
Project 12 Reverse Disco Ball
This circuit is like project 10, but the disco cover spins
in the opposite direction.
Use any of the three preceding circuits, but
replace the disco cover with the other one
included in this set. Compare the patterns on
the ceiling. Place in a dark room for best effects.
Project 13
Disco Ball with
New Pattern
Use any of the project 10, 12, or 13 circuits, but
remove the two blue jumper wires. Now the lights do
not work, so you just have a spinning disco cover.
In this circuit we
reversed the battery
connections to the
disco motor (DM), so its
shaft spins in the
opposite direction now.
The connections to the
LEDs in the disco motor
were not changed.
Use the preceding
circuit, but remove
the 2-snap wire
between the slide
switch (S1) and disco
motor (DM); connect
the end of the blue
jumper wire directly to
S1. Place in a dark
room and look at the
pattern on the ceiling.
The disco cover does
not spin.
