Ok so I haven't used it in anger yet but here is my latest project, inspired by the many already out there on the web.

thats an interesting website. I wonder if a stirrer could be added to the fermeter to speed things up a bit, particularly in lagers.

Top stuff SOS

Simple but effective. Looks like another project on the list for later :( <_< :)
 
Hi Sosman,

Looks like a good project.
Can you tell me where you got the stir bar?

Cheers

The stir bars are available from lab supply places. They vary in price from $4 for a 4mm long one to about $9 for a 70mm long one.

I have an article showing exactly how to build a magnetic stirrer. All I need is for the gallery to come up and I can post the article.

Cheers

Finally got organised. You can see the article on how to build a stirrer here

Damn you guys, you just make me want more stuff :excl:

Just got back from Jaycar with some rare earth magnets :D

Great posts with good info and pics. Keep it up guys.

Great document Gulf brewery.

Another thing to go on the list :ph34r:
 
I know what i'm doing on the workbench at work on monday.

Cheers Sos, what a great and cheap idea.
 
Yes it is a good idea - I have no idea who first came up with it.

The stir bar (40mm) came from science supplies aust. IIRC http://www.ssapl.com.au in Mitcham (opposite Ellerslie Hops).

The magnets came from Alpha Magnetics in Boronia.
 
Thanks Sosman and GulfBrewery, I may have the bits for this project (minus the stirrer) around the house :)
 
I updated the wiki page with the 'final' details. I am waiting for the acid wash to settle before I crank up the starter so it will be brewing a SFA this weekend but I will report back on how well the yeast starter comes up (assuming I don't kill all the yeast at pH 2 overnight).

Sexy. I've occasionally dreamed about a stir plate for my starters.

(edit) digressing a little, what was the shutter speed on your camera? You did well to capture that flea in action.

Wouldn't have the foggiest. The stir bar doesn't go real fast though.
 
I bought some cheap rare earth magnets last year from Oatley Electronics

http://www.oatleyelectronics.com/items.html

A few of the 7mm OD ones for $0.55 may work for the stirrer. They are amazingly strong.

Also had another browse of their web site today. Some interesting stuff. Check out the Bargain Corners 1 to 5 for some interesting temperature control gear.

Also do a search on:

GH1 maybe a good 24V small fan
MF3 12V fans for $4
TC001 interesting sounding temp controller.

Hi Plastic Man,

Interesting site, that 24v 320 rpm geared motor might be good for a grain mill and for $79.00 it would be pretty cheap.

Cheers

Dicko

I have 2 of the TC001 controllers which I was going to use them for spare parts. I don't think it is going to be easy to use them as a temperature controller. If someone has worked out a way of using them, then please tell us.

Cheers

What size flasks do you guys use?
I was thinking maybe getting a 500ml, 1L and 2L.
Also what size stir bars would you use with the coresponding flasks?

Anyone else in Brisbane know a Lab supply place with good prices?
Anyone else in Brisbane want to buy some of this stuff together? (erlenmeyers & stir bars)

That temperature controller looks like it could be ok for controlling a HLT or mash tun etc. I dont see any mention of the type of temp probe it uses or if there is a readout etc. Doesnt seem to much info on that website, not enough to decide if it can be used or not.

vlbaby.
 
Hoops - I started with a 1L , but its really too small, so I've got 2 3L ones which are perfect.

Because of the shape, boil-overs are really easy, so you wont be able to fill it to the volume - I usually go 2.5L in my 3L flask to allow plenty of head space in the top of the flask.
