These lights are based on a simple 556 timer circuit driving a pair of 4015 chips for the powercell, and a 4017 for the cyclotron. Any voltage from 6 to 15 volts may be used to power these lights, though higher voltages may cause erratic behavior that can be fixed with a capacitor (see instructions). They are available for purchase.
The instructions for how to use these lights are below or as a PDF here:
