Project 66
Front & Back Circuit
Assembly:
1. Place base grid supports on base grid C.
2. Place parts on grids A&B, and install into
base grid supports on grid C. Pegs on grid
A should face toward the 4-snap wire
(which on grid C), while the pegs on grid B
should face toward the 6-snap wire, so that
grids A&B are facing in opposite directions.
3. Install remaining parts on grid C.
Turn on the slide switch (S1). The color LED
(D8) shines in one direction, and the light
tunnel (U30) shines in the opposite direction.
Use the preceding circuit but replace either the color
LED (D8) or light tunnel (U30) with the white LED (D6).
You may add the projector to the white LED if desired.
