Pulse Width Modulator. Check.

Ian rocks the pulse width modulator (insert sound of punk rock guitar here). Thanks Ian! Shown below are Lumia's inner workings. On the left is the board that holds the panes of glass and the bulb mounted on the backside (bosco is building the LED configuration). On the right is a prototype of the gear box which will also eventually hold the reflective pinwheel on one side and the motor on the other. In the middle of these is the green and mysterious pulse width modulator. It allows us to slow the RPM down 50%. The gears will do the rest. Dave is in charge of the math for this. By the way, it's me Jenny doing these recent postings. Dave has been busy building! But pretty soon I'll be busy painting ...
