I
have been fiddling with this again ~ it's a very ancient battery charger inherited from my dad...
Newly added level of extra sophistication now comprises of a digital
ammeter, and, a big Zener as a shunt regulator.
With just battery connected...
... then plugged into the mains...
Plus some general tidying up and improvements, such as, a 'P' clip for
the mains lead to stop it twizzling round and round and round.
Only original bits left are the case and the transformer!
