Just the picture of a crystal radio successfully made by myself. It manages to capture several UK channels, most notably BBC Radio 4 and Absolute Radio. For this project I used enameled copper wire BS6811 (British Standard) for the inductor coil, a Schottky barrier diode 1N5817, an a Taiwanese-made crystal earphone. The schematic of the circuit is not fancy at all; you just type in 'crystal radio' in wikipedia, scroll down to the last line and there is the simple schematic i ve been using.
By successfully producing a working radio, i have accomplished one thing in my long list -to-do-before-I-die: Making a radio. Enjoy the pictures.Its not my final destination; instead its just a start to my arduous journey into the world of electronics.
Update (13 June 2012): I repeated the crystal radio design and I managed
to record the AM signal received. Here is the video. I am still using
the same coil with LM386 audio amplifier.The sound was in fact, louder than u will listen from the video.
