Program a temperature profile to step mash grain. Here's how. Make your own PID controller shield for the Arduino Uno (and compatible boards). Can be used as a standalone controller or remotely operated by USB connection to your laptop running a graphical interface. Upgraded firmware based on...

Came across this today, looks like it could be useful for immersed probes such as DS18B20s or thermistors. It is good to 120°C. http://www.adafruit.com/products/1020

I scored a scrapped hotplate on ebay with an intact stirrer. It turned out the heating worked fine as well after I had realigned the front panel. It didn't even need hitting with a hammer :ban: Blog post: http://smokedprojects.blogspot.com/2013/12/stirplate-hot-fix.html

Saw this deal just now on home brew finds. http://amzn.to/1hp9kHQ

Apologies if Tim is a member of this forum. Here is his excellent project. http://hackaday.com/2013/11/22/hack-your-stove-in-the-name-of-homebrewing/

I got a lot of the insides of my power controller from Tier1automation. Wide product range, low prices, free shipping… what's not to like? I have no complaints about the customer service. Once when I ordered something they were out of stock and got back to me within 24 hours, they couldn't...

This document shows you how. The obvious way would be to put the capacitative sensor on or in the sight tube. This is first on a series of articles on methods for liquid level sensing. http://www.digikey.com/us/en/techzone/sensors/resources/articles/liquid-level-sensing.html

I saw this on Home Brew Finds and had to share. A refractometer for $15.99 and apparently free shipping on $25 orders, although that didn't show up for me when I clicked on the link. Still, it's a great deal and comes with 2 years warranty. I tell you this much though - you'll have to join the...

I ordered a bunch of cheap voltmeters from BuyInCoins (8 for $20) intending to hack them for use as temperature displays. They haven't arrived yet, but luckily in the meantime somebody else has done all the hard work of figuring out how to convert them to general purpose displays...

I don't hear too much about the Johnson A19 freezer controller but it is cheaper than the Johnson A419. Has anyone tried it out or have comments?

Anyone had any experience with the JLD612 PID controller from Lightobject? I have noticed that quite a few people who follow my smoker controller build opt for this model. It seems to tick all the boxes. Worth a recommendation? Link: http://amzn.to/13t689d

Not mine. Be quick! http://philadelphia.craigslist.org/hsh/3879642725.html

Don't steam up your garage, make an extension cord for your kettle and boil outdoors. I have several L6-30 female connector bodies, 30A 250V, Woodhead brand, brand new and still in the packet. $5 each. Shipping $3 for one, multiples PM me your zip code.

This is my clunky, but robust, folding brew table. 3/4" bolts fastened to steel beams support hinges welded from scrap metal. Eventually I will suspend the table top from heavy chains but for now it is propped up on kegs and perfectly stable and flat...

Not mine but someone needs to jump on this! http://philadelphia.craigslist.org/wan/3819219472.html

Do you need L14-30 hardware for your power controller? These pieces saw use in theatrical audio and lighting equipment and look clean and in good shape. All sold. === I also have L6-30 hardware which is great for connecting to kettles and heating elements. Surplus to requirements because I...
