    Yeast Starter Stir Bar


    I'm planning on building a yeast starter stir plate.
    I got a electronics project box, a 12v Pv fan, a 12v adapter, got some hobby magnets .. but can't find a stir bar anywhere.

    Anyone know where I can source one near Cape Town ? Thx

    I bought mine from Home - Cape Lab Equipment but tbh I think they just got it from a distributor in cape town.

    otherwise these guys Magnetic Stirrer Bars 6mm x 30mm each | Masiye Labs
    they are on bid or buy as well Other Business, Farming & Industry - Magnetic Stirrer Bar 30mm x 6 5/Pkt for sale in Johannesburg (ID:464883511) (bidorbuy.co.za)

    buy two or 3. It's a right of passage to dump it in with the beer

    That's what I thought. I was collecting fans old hard drives ect but then thought where am I going to get a nice box. Plus I heard that aligning the magnets can sometimes be a pain.
    I'll keep my parts to build another. Please show pics when yours is done. Remember to put a led in

    I like building the stuff myself - guess that's part of me and self induced hobbies.
    One plus point is that if something breaks or stops working , I can fix it.

    Next I'm building a pre-chiller for my immersion chiller.
    I'll post this with details in a sepperate thread..

    Lol you guys are alot better than me.. I raided my broken computer for the fan and the hard drive.. I used an old ice cream container as the housing.. it took a while to get everything aligned and then I ended up just sticking the magnets on with prestick. One day when it doesnt work anymore I will do a proper build but for now it works and it spins like a dream, so I will leave it as is.
