I started this project with a view to proving the concept of running from a lower voltage battery pack while using an industry standard IC such as the Texas Instruments TL497A and then replacing this with a PIC processor such as a 12F675 to generate the pulse stream and carry out the simple logic required to regulate the output voltage. These pictures show just such a prototype on this breadboard driving a 1.6Watt LED lamp.
