Hello John.
I hadn't seen the original bull, so thanks for the explanation.
I have one of the 5, ultra bright LED torches which were being advertised
on TV last year at 9 quid.
It's performance is adequate. I am keeping an eye on it's batteries,
though (3 x 1.5V not LIR) in case of leaks.
The selling point of the torch was that it is very low consumption and,
therefore has a long life. That had me wondering about a rechargeable.
I also own one of the 'squeezy' torches. You get light as long as you
sqeeze the lever on the side. O.K. in emergencies but your hand gets tired
if it's more than a few minutes.
I have mentioned before how, in 1966, I built a radio which had a
clockwork motor and charged a bettery from a peculiar lighter. It worked
quite well
one wind on the foldin handle was good for a couple of hours.
There were no rechargeables in 1966, not even Ni Cads, so I could only
make one or rely on just the spring winding down.
I was wondering what the capacity of a LIR 2032 was. It might be worth
knocking up another one, especially as simple radios are far smaller than
in 1966 and tend to be built around an IC not trransistors.
All the best from - Ian, G0TEZ @ GB7FCR
