to be honest not sure if its rpm or more likely power % but its at least an indicator that i can use to set the same 'speed' to each time

i assembled all the parts for this. rigged up to test before installing in the box but nothing. my fan has 3 wires, earlier post said that no harm can be done by connecting wrong wires. after various combinations i got a burning smell and a little smoke from the fan hub! i guess I've burnt out the fan motor?

I've checked the out put terminal on the controller and 12v is fine. little led lights up and varies brightness when knob turned.

does polarity input to the controller matter?

shall i just order another fan?

Most fans have polarity protection which means if it's connected wrong it simply won't work, but shouldn't cause any damage. It sounds like yours didn't have protection if it's smoking.

For future reference, I found this with a bit of googling:

If you have a 3 wire fan and you don't know which wire is which, hold the connector as shown in the picture and the wires are:

Tacho at the top (not needed)
Positive in the middle
Neutral at the bottom.

That goes for all 3 wire fans, you can't necessarily tell from the colours of the wires because they are not universal. (source)

Finally gathering parts to build one of these, most parts free from work (Fan, HDD Magnet, 12v PSU) got the PWM and the Stir bar on their way from ebay.

Where is the best place to buy the mounting hardware from, and by best I mean the cheapest

And so I need a 2000ml flask for a decent sized starter or would a 1000ml be adequate?

I only have 1000 ml and I wish I would have gotten a 2000 one instead.

Thanks, I'll go for the 2000 then, to save some similar future extra expense.

Still after some cheap screws and nuts if anyone has a link?

I've had glassware (beakers and flasks) off these guys:
https://www.creamsupplies.co.uk/acad...sk-2000ml-huge

The 'academy' stuff is good (and cheap) and boiled wort can be cooled in sink of cold tap water without the glass shattering etc.

postage is also cheap.

I have had 1litre flasks in the past but just ordered a 2litre one as for larger 1l starters is required.
