Hi guys,

Nice effort Slider.

If you want to try other minerals with the cat whisker,  you could use things like boronite - zincite - hematite - galena - molybdenite and while not a natural mineral,  you could also experiment with a piece of pure silicon.

And.....for that out of this world experience....(pun) you could even use a small piece of meteorite.

One thing to keep in mind about this circuit as well as the raudive circuit and untapped crystal radios in general is that their designs are intended to be used with high impedance earphones / headphones.

If you want a cleaner / clearer sound you might want to think about using an impedance matching transformer like the Bogen T725.

Good Luck,
