Was looking at a one wire thermal probe which will sort all of my home brew temperature monitoring requirements. You may recall I think my current brew went a bit wrong because my thermometer was broken, and I had a plan to build some computerised temperature monitoring...
Good grief listen to me "you may recall" like anyone is reading this apart fom myself. Anyway future me, you may remember a time when you tried to make that Doom Bar clone in a bucket and it may or may not have tasted of crap because you got the temperatures wrong. Well here is the blog post from just after you made that beer but before you got round to doing another with better temperature monitoring...
I'm not quite ready for the full brewpi.com1 experience yet but I bought the probes2. Was going to get just one of these from coolcomponents.co.uk3 and got right through to entering my card number before spotting it was "out of stock". I was going to buy just one of these Waterproof DS18B20 probes, for 7 quid something with nearly 2 quid postage, but instead from the ebay2 I've got five of them for that price. And from the UK too, free post, dispatched same day. I hope they're as good quality, will have to see. I can use a couple of these for the brew and then more for general environmental monitoring!
These are one wire which means I can use them with the raspberry pi, I assume it means they give a digital reading as you can connect them directly to the GPIO pins of the pi, and my existing temperature monitoring components cannot me, afaik.
Here is more info4. I wish I had them in time for the free time I'll get tomorrow evening when Clare is out...
arduino: Microcontroller, hardware prototyping platform, a tiny specialised computer.
raspberry pi: Credit card sized super cheap computer, awesome.
