A page concerned with spark transmitters, early radio etc. Being fascinated by the development of wireless technology which took place over a hundred years ago, I decided to attempt to replicate some items of early wireless equipment, beginning with a spark transmitter and induction coil.
Favourite links on a variety of subjects.
At the moment, only one item, though if you make your own telescope mirrors, possibly useful. The quick and dirty method to find the focal length of a concave mirror in the rough ground state.
Currently (24/12/06) disabled due to over 300 spams a week. Hopefully back in early 2007.
