Step 6: Mount the moving mirror
Poke a small hole in the housing right above the lens head.
Stick the wire holding the mirror into the hole until it touches the lens head.
Fix the wire to the head. we used a sticky putty-like glue made for putting posters on walls. A small ball 2mm across is enough. It can also be done with a small dab of hot glue or superglue.
Let it settle for a bit, then carefully move the head around a bit with your finger. The mirror should tilt but stay attached to the head.
If you made the hole too big, glue a layer of strong sticky tape over it, and poke the hole in that.
