Finally: network enabled fermenter temperature controller

[JimmyM]

how much for the oled display? whats the resolution?

No - I havent done anything like that for years, since college.

Now that would be cool!! Group buy of DIY network temp controllers and a day out putting them together, together!
Ahh I can see the android and iPhone apps and web portals now.

Our friends in tog did a "design a PCB" day a little while ago - i remember one of the lads in work sending it on to me.

If you want a hand with any of this stuff let me know. I have some experience with it - I used to work for Maxim as an Apps Engineer and designed a SMPS while I was there. I know a bit about the 1-Wire DS18B20's you're using too and have messed around with an Arduino using them. I can get you free samples of Maxim parts if you need them too - just off the top of my head - ADC's, Temperature Sensors, 5V Regulators - all that stuff. Just let me know.
I used Proteus and OrCad for my designs - afaik Eagle isn't completely different for capture and layout - but I don't have access to it so I can't comment exactly.
There are a few free PCB tools out that are pretty good - check out Designspark, i've heard good things about it - a little biased towards RS though!

I was thinking that a safe and easy way of turning heaters and fridges on and off would be to use some wifi/bluetooth or IR sockets that are used in home automation setups.

A wifi temp probe and a few scripts and you could have one rasp pi or a pc controlling them all.

Somethink like http://www.ebay.ie/itm/OWL-Multisocket-Power-Saver-Strip-4-Individual-Sockets-Remote-Control-TSE007-010-/140872270509?pt=UK_Computing_Other_Computing_Networking&hash=item20cca442ad#ht_2268wt_1033 would give 4 sockets that could be switched on or off. I've seen similar in lidl or aldi before. They seem to be cheap enough to pick up.

Somethink like this might save someone messing around with mains voltage

I think the one i had was zx +2
