    Beer clearing in bottles but not keg

    The difference is where you are sampling from. In bottles, the yeast settles to the bottom, and you pour the beer off it, leaving the sediment behind. In kegs, the dip tube is at the bottom, so you're always sucking sediment up with the beer. Stuff will keep dropping out of the beer as it ages...

    Floating dip tube optimisation

    I'm seriously considering diving into keg fermentation, so I'm looking at floating dip tubes. I want to put these in my serving kegs too. I have a concern with how to use them without losing a lot of beer though. All the ones I've seen suspend the end of the tube on a hook, an inch or two...

    Using A Kettle Element....covering Wires Etc

    So much faith in the mystical powers of an RCD or a chassis earth. So much facepalm. RCDs are great, they'll protect you from one the more common shocks - touching active and earth (including an earthed chassis, kitchen sink or the actual dirt). RCD detects more current in the active wire than...

    Using A Kettle Element....covering Wires Etc

    Hmm...probably should have written a reply to "it's not the voltage that kills you, it's the current" back in the day. A 230v circuit with a 1A fuse will be just as lethal as one with a 10A fuse. Currents over 30mA through the heart can be lethal. Your body's resistance will vary greatly...

    Wonder if he ever "fixed" it. Wonder if he got a belt off it, or worse.

    Tight Arse Stir Plate

    I know I've been gone for a while, but I thought we'd cleared this up a long time ago. Do not use a pot. Use a variable regulator or a pwm (switchmode) fan controller. There have been several circuits posted in this thread, including one of my own.

    Tight Arse Stir Plate

    Most switchmode drivers have a minimum on time for stable regulation. If it's a cheap controller, this can be quite a high duty cycle. The designers of your LED controller may have added a series resistance with your control pot to allow for this, and erred on the side of caution. Either way...

    How To Purge Fermeter With Co2 If A Bottler?

    That's for a bottle about the size of those little oxygen tanks. A 5kg cylinder, about the same size as a fire extinguisher. You can rent the bottles from CIG and BOC, but it's an expensive way to do it.

    How To Purge Fermeter With Co2 If A Bottler?

    It's pretty easy, really. You put some beer in it.

    Brand New Mm2 For Sale

    Sorry, what? You've got a mm2 which you're very happy with, so you bought a new one and want to sell the new one? Buying a new one and selling the old one I could maybe understand, if these things deteriorated at all (which they don't), but otherwise it makes no sense

    Tight Arse Stir Plate

    Still you. Sure, some of the staff are retail bunnies - it's a retail store, you get that. I've not yet walked into a store that didn't have at least two people who knew their stuff, though. If you can't find them, maybe you're unlucky enough to be in a store full of n00bs and idiots. Maybe they...

    Tight Arse Stir Plate

    Most of the people on this forum didn't know what PWM stood for before this thread. I didn't know what PWM stood for until about the second or third year of a computer engineering degree, and I majored in embedded systems. My point is that there's a vast wealth of information in the field that...

    Stc 1000 Temp Controller .... I Think I Fried It?

    Nothing obviously blown up. If you've got a multimeter, check for resistance between the AC input pins, and then on the back between the two output pins of the transformer. They'll be the two (or three, if it's centre tapped) pins furthest from the AC input, and the transformer is the big orange...

    Stc 1000 Temp Controller .... I Think I Fried It?

    Yup, if you've got that acrid smell it's probably burnt semiconductors - output triacs or something. Yes, if you've only lost the active that shouldn't short anything out, but if it's a loose connection arcing back and forth it can cause things to fail in exciting and unpredictable ways. Can you...

    Overclockers = A Great Forum For Technical Advice

    Much like reading about electronics here :)
