Stir plate question

[shaw26]

Hi all,

Been looking at making my own stir plate as it seems easy enough but then I found in the cupboard an electric protein shake mixer. It's like a mini blender that you can charge with usb cable.

My question is would it be ok to use as yeast stirrer?

Yeah if you want to send your yeast into outer space.

Speed that bad boy rotates at you'd have no chance.

Ok fair enough just thought I'd ask

Couple of reasons why not:
1. It will damage the yeast.
2. It isn't designed to run for hours on end and will burn out.

Making your own is relatively cheap and easy.

As it's just after Christmas you may even have an old Quality Street plastic box to use as per one shown on the Forum.

When making your own Stirrer a few things to remember are:
1. Cheap stuff from China can take weeks to arrive. (My magnets took six weeks!)
2. Be generous with the room you require. (Which is why I very much liked the Quality Street box conversion.)
3. An old 12v battery makes an ideal power source. (I use two old ones from a disability scooter; they can both keep the stirrer sunning for 48 hours.)
4. If you go the 12v battery route you will need a Battery Charger.
5. Check out the writing on my own Stirrer. I nearly threw a Spinner Magnet into today's brew!

Enjoy

Nice one Dutto.

There is also a thread about making one for less than ten quid - https://www.thehomebrewforum.co.uk/threads/how-to-build-a-stir-plate-for-less-than-ten-quid.65471/

I made mine out of an old PC fan, one of these https://www.amazon.co.uk/dp/B00Y2AV4G8/?tag=skimlinks_replacement-20 , an old plastic box, and use an old PC power supply to power it. The power supplies have a handy 12V rail you can run the fans off of

This is what I did, and it works a treat. I'll be firing it up tonight to build up some Wyeast Trappist High Gravity 3787.
