Please note
The OPITEC range of projects are not primarily intended
as toys for young children. They are designed as a a
teaching aid for Design Technology to encourage pupils
in a range of practical skills. These projects should only
be attempted with the help of a qualified adult. They
are not suitable for children under 3 years of age. They

Instructions
Using the pattern (Page 5) mark out the holes and cut out for the switch on the blank CD (1) . Use a centre nder to draw a
middle line ,the centrs of the holes and the cut out. Finally drill the holes as shown
Note: Drill a 1mm dia pilot holes rst!!
To cut the hole for the micro switch (7) drill a 3mm hole in one corner and insert a fretsaw blade through the hole and saw ot
rhe shape.
Mark out the position for the battery (6) see pattern (Page 5 ) on the front of the CD (unprinted side (1)
Note: Keep to the sizes as accurately as you can! Work on the unprinted side of the CD! Do not use sellotape!
Step 1:
Position Motor (8)
CD-Reverse side
(printed side)
Step 3:
Position Batteriy
holder (6)
CD-Front (un-
printed)
Glue the battey holder (6) with hot
glue on the unprinted side of the
CD (1) Thread the connection cable
through the 3mm hole
Note: The battey holder (6) must
sit exactly on the marked area.
Step 4:
Glue the slide switch (7) in the slot on
the same side as the battery holder.

Step 5:
Insert the resistor (9) to the side of the
switch (7)as shown on the front of the
CD (unprinted) in the 2mm hole.
Step 6:
Insert the two Light Emmiting Diodes (4)
from the printed side into the 5mm pre
drilled holes, glue them in place.

Step 2:
Lay the CD on the pattern(Page 3) so that the printed side is uppermost. The posti-
on of the motor (dotted line) ist can be seen through CD. Now squeeze a worm of
hot glue within the dotted shape Glue the motor (8)carefully with the cable facing
the hole

Step 9:
Stick the reducer (10) into the approx.
ø3mm bore hole from above (see pic-
ture)!

Step 7:
Solder the black cable of the battery holder (6) on
the middle connector of the slide switch (7).
Connect the red wire of the battery holder to the
anode of the motor-sided LED. For this purpose,
cut the red cable, so that it can be soldered to the
anode. Re insulate the cable ends and after that tin
and solder them.
Also solder the red cable of the motor (8) on the
anode of the motor-sided LED. For this, cut the red
cable, so that it can be soldered on the anode. Re in-
sulate the cable ends again and tin and solder them.
Now twist and solder the cathode of the motor-si-
ded LED on the anode of the external LED. Moreover
solder the cathode of the external LED on the upper
leg (see picture) of the resistor (9).
Take a strip of the jumper wire, which is approx.
80mm long, re insulate both sides and solder one
end on the upper leg of the resistance. Connect the
left end of the jumper wire with the outer connec-
tion of the slide switch (7). Solder the black wire of
the motor (8) on the free leg of the resistor (9). To do
this, cut the cable, re insulate and solder it.

Create the center of the base (2) by
drawing diagonals and drill a approx.
ø3mm hole into the center. Glue the
foam rubber sheet (3) on the backside.
Let it dry!
Note: The base plate can also be colou-
red.
Step 8:
Insert the nished shell as shown in
the reducer in the base plate (1).
Last insert a block battery (9V) into the
battery holder.
Done!
