The answer was yes & no....

Yes if there was sufficiently thick insulation around the cold compartment...

In this case that meant that the cold compartment was half the size of a teacup...

Or alternatively, no, unless you had half a tonne or ton of lead acid batteries to supply 4A for 48hrs.

Lithiums weren't sufficiently developed at the time & were vastly expensive.

Like most of these things, I seem to recall that it was exponential... tending to about 5 deg C as a minimum for the LIDL beach cooler thing I was experimenting with.

Yep, exponential and I'm expecting to get down to about zero in the 18C kitchen we have.

How far did you get with playing with that Dragon?

Not very; got as far as it refusing to read the WAV file as program... dunno why yet.

Maybe I'll try writing some of its own code to the pc soundcard & have a shuftie at that...

Or not.

Best of luck, I ran a datalogging program overnight to graph mine out.

Then had to write something to throw away 90% of the points coz I had too many for the graphing s/w to cope with.

Anyway, enough frivolity & fun... time to cuddle the cat again...

She threw up on the window sill behind the tv this morning...

Ho hum.

Byeeeee

I am using a more flexible method. It is called "Open the door every hour and see what the fridge thermometer says and write it down on the bit of paper".

I am using a specialised graphic application called "NickFitz does a nice graph".

I do worry about your cat, you know.

Bye!

I don't know why I do, but I do.

Experiment: a £40, 14 litre mini-fridge from Argos: what is its cooling power?
Switched on at 18:25 in a room with a temperature of 18°C. 5 normal 75cl wine bottles put in there which were also at the same room temperature of 18°C. Total liquid: 3.75 litres. Also a kilo or so of glass bottles.
