Right before I started my first AG batch (just finished my 3rd), I dropped and shattered my thermometer, luckily I had a thermocouple probe sitting my car that I borrowed from work (used it to test the coolers temperature loss)... Unfortuantely, my temps were all over the place before I got them to where I wanted too (water too hot or not hot enough..etc), so I thought it might be a cool idea to log those temperatures to see how well I was hitting my target temps for each brewing session...
So I came up with the following "Mash Monitor"... I'm still working out some of the bugs, and the temperature sensors (thermistor) need a bit of work with accuracy and stability (temps change too much, too fast.. maybe I need to attach them to a piece of metal or something??)
Anyways, so I have 2 sensors, one to monitor the water on the stove, and one for the mash in the cooler.. There are a couple of threshold alarms, and also alarms for each step, and a few other 'features'... Here's a screen shot of the program:
Here's what my setup looked like:
And then here is the hardware... It's from an old project, so there's a bunch of other junk on there that's not needed... If/when I do a layout for it, I think I can get it to probably about 1/8 to 1/4 of this size...
