Thought I would pass along this deal on Arduino shields: http://slickdeals.net/f/6311860-huge-arduino-clearance-at-radioshack-b-m-dont-trust-the-marked-prices-shields-starting-at-2-48 I am thinking this is about as cheap as it gets for these as I have never seen them cheaper.

I couldn't find much about people using arduino (or any microcontroller for that matter) to monitor pH. I stumbled across this unit on e-bay: http://www.ebay.com/itm/pH-Circuit-Sensor-for-Arduino-/200779624796 It says it has temperature independent and dependent readings. It says that...

Here is a quick and dirty diagram of a prospective brewing system I have been thinking about. I don't think I have seen a non-recirculating build like this before and I feel for sure I have to be missing something. The process would look something like this: -Set temperature controller to...

My freezer (soon to be keezer) has a built in thermostat already in it. Could I just disconnect the red and black wires from the freezer's thermostat and attach them to a digital thermostat without having to do anything else? I could then put the new thermostat's thermistor where the old one...

After a somewhat frustrating first week kegging, I think I have narrowed down the culprit of some issues I was having. I have taken the CO2 tank and cylinder out of the keezer and let them stabilize, disconnected from any kegs. Now when I purge the lines of gas pressure and dial the regulator...

I am a complete noob to kegging. But, I got a complete setup, went to "airgas" and bought a CO2 tank. After hooking everything up and dialing in the regulator my beer began to pressurize (as I assume is normal). I started out at 30 psi to force carb for the first 24 hours and then I was going...

Do any of you know of any diy's of people building their kegerator out of the guts of an old fridge or freezer? I have seen many many many conversions, but I haven't been able to find anybody who has taken out all of the guts and put them in a custom, insulated keg box. The possibilities...

What do you guys think about buying this freezer for $35 for a keezer build? Its obviously got a lot of rust so do you think it would be too much trouble sanding it all out of there?

I am going to take the plunge and buy a kegging setup. I was thinking about buying: http://www.homebrewing.org/Homebrew-Kegging-System-PIN-LOCK_p_1763.html http://www.homebrewing.org/Set-of-Four-5-Gallon-Pin-Lock-Cornelius-Kegs_p_1549.html...

Being a college student home brewer, I like to pinch pennies where ever it is possible. One of those places is yeast. Yeast washing saves me a very significant amount of money over the course of many beer batches. I was hoping you guys could suggest what yeast strain is the best for each...

I want upgrade my kettle to an e kettle but am realizing how expensive it can be to make one that automatically controls temperature. My question is: Is it a cheaper alternative to buy a "dial" to control the amount of electricity flowing to the heating element? If this is already covered I...
