Or is there something in jaycar that's suitable I can get today? :) These and and these look similar I guess, not sure if either of them are suitable.

I double shielded and earthed the shields on all the 240V lines with foil - heatshrink - foil - heatshrink to no avail! D: Works fine with the switch on 12V though, and on 240 I don't even need the pump hooked up and it does it. Flick the pump on and off a few times and the display...

Yep, confirmed my display scrambles occasionally when I start the pump. Probably 1 in 5. I think I'll try the foil shielding thing, then get one of those caps that matho linked if that fails.

Hmm, I wonder if I can fit one in my box somewhere? I could just chuck one of those suppressor caps across the pump terminals I guess, I do like the idea of isolating the pump from the controller board though. Will putting in a second relay really solve it? isn't the pump already behind a...

doh, of course. Thanks for clearing it up :)

Thanks, but that wasn't what I was asking. I was asking how Davethebrewer hooking up a relay across the pump terminals to drive 240V will be possible, or if he's using some special kind of relay. If he uses the kind of relays that I know about, then to actuate the switch in the relay you need...

How does one of these work? I thought the pump terminals on the PCB were just basically a switch, so no power to drive a relay?

I've broken a bunch of them too, and had rats chew through plenty of 20L handy pails as well. Bunnings don't sell 25L ones here, only 20L.

One of mine was damaged recently, except the little spring that's part of the magical pressure-measuring doohicky behind the gauge was all bent and ****** as well. Try as I might no amount of bending back fixed it. $29.50 from CB for a new gauge fixed the problem.

Haven't actually hooked mine up yet, will sus it out soon and let you know

Here's a pic of it all wired up. No brewery yet, but I figure is the controller thread so controller pics are ok :P

Here's a couple of pics. I just drew the wiring in paint from memory, pretty sure thatll do it, viewer discretion advised etc etc

All that would happen is that the 12V pump would stop because it had no power. And there would 240VAC supplied to a 240V IEC socket (that a march pump, for example, might be plugged into). My switch doesn't force 240V across the 12V socket pins, and hence the arduino board, shield and back...

No worries, I'll post a couple photos later today. I used one of these DPDT switches. The common terminals are hooked up to the pump relay terminals on the controller, and the switch chooses between a 240VAC live wire connected to the march pump power output, or a positive 12VDC line connected...

Interesting you say this, big eye is one one of my favourite session beers, but i was extremely disappointed with punk, i thought it poor form of brew dog to try and hock it as an ipa. Those beers are worlds apart, imo. Has anyone ever seen a reasonable amount of stock at dans? like, more than...

Put together my controller finally. Well, I've had the PCBs done for ages, but man making the controller box takes a f'n long time, and stripping like a million wires. I wish I'd invested in some wire strippers. I got one of the kits with the backwards transistors, lucky I got the message to...

Loving your setup rodda, do you have a build log anywhere by any chance?

No idea, and probably no help, but the old skinny cyclinders (35 or 40L i think?) have been replaced by fat 60L ones for the same price, and my adaptor fits no troubles. Stoked about the extra volume.

Guess you didn't actually look at the results? They're all for Epic Armageddon. The average kiwi IPA. Not the 65% Brewmeister Armageddon that was released a few weeks ago.

Whaaaat? I refuese to believe anyones opinion could be so wrong! ;) Anything by 8 wired is amazing, closely followed by yeastie boys pot kettle black! There's a lot of difficult to obtain US and scando beers there too!
