I am a real newbie (~1 year) to electronics and just have the basics, but having recently enjoyed building a few cheap Chinese radio kits and also enjoying survival/camping stuff, i also have several ferrocerium rods of various diameters and lengths. Then (uh-oh!) i started wondering if they would work..?? Anyone know, please? Just plain curiosity, but i am also looking at building my own breadboard radio based on the TA7642 chip. Thanks!
