Whoa, don't know about being 'better' Smitty, just thought I'd make one when I first got into this EIS making, and it was copied from public domain, the jewellery box was my idea that's all, a draw to store the stir bar <g>. "How important is it"? If brewing larger volumes it keeps everything moving, and I believe helps reduce possible larger particle formation whilst brewing. Sorry, I don't pretend to know the exact science of it, just what I think and do. What I will say though is, if I brew anything over 250ml, or 300ml maximum, I most definitely use the stirrer. I normally brew just over a litre a time. With your setup you probly don't brew large volumes do you? So a stirrer may not be necessary in your situation. N.

I may make one using your designif you think the brew is better with the stirrer.

If I knew how to put a photo of mine on here I would, but I got this from ideas in the public domain, and there's pictures available as well if one searches DIY mag stirrers. I use kids jewellery boxes, they have a draw for stir bar storage as a bonus.Open lid and rip the mirror off, and everything else out of the top shelf.Cut hole in lid big enough for computer fan to be fixed underneath. Cut the plastic speaker cover from old radio or whatever and fix that on lid top covering the hole above fan.Wire an on/off switch connecting the fan, the switch and a power adaptor plug fixed to the box and that's pretty much it. Computer fans are 12vdc so if one can get a variable voltage power adaptor which can be lowered to lowest voltage setting to keep stir bar spinning you've got a magnetic stirrer. All you need is a hole saw for the lid, some soldering practice, some wire and switch etc. Dead simple to make and works a charm for me. N.
