Lifter - Elenco Electronics SC3DMEG Instruction Manual

Project 84
Assembly :
1. Place base grid supports on base grid A.
2. Place parts on both sides of the double sided grid B, then install grid B into base grid supports on grid A.
3. Place remaining parts on grid A. Mount the gear insert and the large gear on the orange motor (M9). Place the
magnet in the center of the gear.
4. Mount the Illusion card holder onto the clear motor (M4) and insert string into the slots as shown.
5. Wind the string around the shaft several times to get it started.
6. Tie the other end of the string to a 45 degree vertical snap wire (V2) or base grid support.
7. Place circuit so the motor is over the edge of the table as shown.
8. Place the 45 degree vertical snap wire on the floor and wind the string around the shaft so it is straight.
Turn on the slide switch (S1). The gear starts turning as the red and blue LEDs (D11 & D9) light. When the magnet
passes the reed switch (S9) the 45 degree vertical snap wire (or base grid support) rises then falls and the color2
LED (D12) flashes. Push the press switch (S2) if the orange motor does not start.
If the base grid support does not have enough weight to pull the string down, then tie the string to something heavier.

When the motor spins
backwards it generates a
voltage which lights the
color LED.
