I am retired and have been for some time
I am 64 and live in Staffordshire , England . Although I qualified in Metallurgay and Chemical Analysis my hobby is High Voltage Electrics - Tesla coils etc.
I do , occasionally display , talk / lecture on these things
I did pass my Radio Amateurs Certificate in 1983
My maths is very rusty now but I enjoy making spead sheets with macros to help with some of my electrical / electronic calculations
Some of my stuff is on you tube under Sparkfishes
