An interesting diversion for me, right now, is looking at a decent sine wave inverter - we're getting too many outages in the area, and with the weather patterns getting more extreme, ...

 

A reputable dealer had a high powered unit on a "what's left in the warehouse!" sale, and so grabbed one ... bad news is that it died, completely, on a trivial load for its size - making all sorts of spluttering noises, now - so, today, back to the shop, .

 

The point is that it was supposedly "pure sine wave" - and one of obvious uses of this was to trial music systems running off  'poor' power - but haven't even got to first base yet ...  .
