Assembly:
1. Place base grid supports on base grids B & C. (Grids B
& C are placed adjacent to make a full-size grid.)
2. Place parts on grid A, and install into base grid supports
on grids B & C.
3. Install remaining parts on grids B & C.
4. Add the mirrors, lined lens, and Q4 attachment.
Turn on the slide switch (S1), and carefully align the mirrors
so light from the white LED (D6) reaches the
phototransistor (Q4); an alarm will sound when you
succeed. Push the press switch (S2) to add light tunnel
(U30) effects.
Project 26
Two-Mirror Circuit
Use the preceding circuit but remove the color LED (D8)
and the light tunnel (U30, and the blue jumper wires
connecting it). D8 and U30 do not affect the mirror-alarm
part of the circuit.
