Yes, first time this year. My fam bought me a dehydrator for my b-day and I have dried peppers, herbs and made beef jerky (delish, btw)
I dried Malegueta peppers and on a whim (because I had so many) I dried pepperoncini (both Greek and Italian). The Malegueta peppers were small and dried fairly quickly, the pepperoncini took about twice as long. I ground them using a coffee grinder. Took the stems off but left the seeds in.
Got the dehydrator at Bed Bath & Beyond with 20% discount coupon.
Here is a picture of it - NESCO brand - wonderful machine:
