Diode Radio for Low Impedance Headphones

Based on a Labs project | October 2011 | Find it here
If you ever look at construction notes for building old detector type radios the type of headphones specified always have an impedance of 2 × 2000 ?. Nowadays the most commonly available headphones have an impedance of 2 × 32 ?, this relatively low value makes them unsuitable for such a design. However, with a bit of crafty transformation these headphones can be used in just such a design.
