New game - I'll pay AUS $25 to the person who can come up with the best DC to DC converter design. It should be low in cost, capable of producing at least 10mA @7V (~70mW of power) from a 5V source. Additional, desirable criteria in the design would include: compactness, protection, low component count, efficient, testable & robust.
