    Thanks Stange Steve, I finally got all my parts today and built the beast.

    I opted for a 3 litre flask which I felt would be handy for larger starters and it makes a cool vortex in the three inches or so of water I have tried so far.

    It's a genius bit of simplified engineering which I would never have figured out without your template.

    I am looking forward to using it for my first lager starter in a couple of days :)

    I'm sure. Long ago in this thread I said I used a cpu fan with some magnets. A jar of science and a USB 5v thingamjig. Cost me next to nothing.

    @merrydown glad it was helpful :hat:
    It should easily get a good vortex in 3L, though I've found I have to throttle back a bit on the speed to keep the stir bar stable. Just a little dimple in the surface is enough to keep the yeast in suspension anyway.
