I would like to build a temperature controlled Mash Tun. If there is anyone out there that has a great resource for items such as a PID temp controllers, thermocouple probes, and SSRs. I have been looking but the PIDs I have found are at least $90, and most $150 or more. Is it really necessary to spend that kind of money?
Also, any information about matching the products would be helpful
Thanks
A Ranco ETC unwired is around $50 for a single stage, $90 for a dual stage.
What is your anticipated level of involvement? Do you want to buy an off-the-shelf system, or are you willing to build your own? If you want to be more on the build-your-own end of things, check out BrewPi (http://www.raspberrypi.org/archives/2129, http://brewpi.com/), which is software that runs on a raspberry pi or an arduino.
Have you looked at http://theelectricbrewery.com ?
It is a great site.
