Nice project, DrewPaulDesignsSomeone said they never learned about crystal sets and such at school. I was a physics teacher back in the 1970's and I *did* teach the children the circuit and operation of crystal sets... along with loads of other off-syllabus things. At that time we didn't have Government inspectors breathing down our necks about national curricula and targets. We just had to make sure the kids passed their exams which left plenty of time for *interesting* asides.Incidentally, harvesting RF from radio stations might be illegal in some jurisdictions but this device is on such a small scale I don't see how anybody would notice or care. Wouldn't a metal clothes prop in the garden 'suck up' RF just the same?
