This was before I knew what a boost converter was, so I used the Aahz’s Boost Converter design (member of the forum, see here). A blurry schematic (the only one I have!) of his design is shown below.

The only thing I would do differently would be to improve the MOSFET switching, as it gets very hot during use. Something is causing the MOSFET to remain in it’s linear region for too long.
