I got a germanium disc from ebay, and I did a quick test by and found that pointing a scalpel to it it works as a point contact diode!
It is a bit rough but it works!


I'll try obtaining something pointy and see if I can get better performance.

Nice, I love raw electronics. If you havent seen http://www.sparkbangbuzz.com there's a ton of useful experiments in there. Crystals are awesome :-D
