Formers for winding inductors

On the way back from GQRP Mini convention we stopped off in a couple of service stations and to the probable puzzlement of the travelling companions Henning and Clive I collected a few items each time.

Back in the shack I have started to look at different coil formers for use in homebrew so will add them to the ones I already have.



From left to right they are straws from Burger King, Starbucks, Costa Coffee and wooden stirrers from Little Chef. The largest is the Starbucks clear straw.

More info to be updated after testing.
