Pimp My System / Corney keg Thermowell
« on: January 16, 2018, 05:44:48 PM »
Ok, here’s my latest project…

I’ve wanted to put a thermowell into a Corney keg to allow me to use my wireless temp controller to control the temps in my kegerator. So I picked up a couple of keg post adapters from Bobby at Brewhardware. I had a spare liquid-out post and a 16″ thermowell.

I took the liquid-out post, and drilled it out to accommodate my digital thermometer probe…

I took one of my corney keg lids, drilled a 1/2″ hole,

and carefully ground the opening until the post just fit,

and silver-soldered the post…

another view…

I just put a standard o-ring on the thermowell, insert it into the modified post, and insert my digital thermometer probe.

If and when I make another one, I’m going to move the post more to the center of the lid.

I have two, and have written some code that allows me to use a Raspberry Pi to monitor and store the data on an SD Card, and display it on a local webpage. Works great.

If anyone is interested, I've posted my code to my github

Has anyone here used this while fermenting in kegs?


I'm using a RPi3 with my own software. I just set the RPi3 right on top of the sanke, and run the wires out through the port on the back. Works like a champ.

The new Pi 3 has both bluetooth and wifi on it.  I'm thinking it might make a good data collection/wifi repeater device for use with the brewometer.

I've got some python and php code that runs on a Raspberry Pi 3 / Raspberry Pi 2 (with a bluetooth LE dongle)  LAMP server. It interrogates the Tilt/Brewometer once a minute and logs the result to a MySQL database. Some additional php code displays the information in a graphical form on a webpage. It does require some knowledge of linux (I use debian, but raspbian lite also works. Here's a screenshot of the graph.

It should be noted that the temperature displayed is off by about 4 degrees, based on the reading from my ESP8266-based Temperature controller, which has a temperature probe placed directly into the wort via a thermowell.

The SG reading is also off by about 4 points, based on readings taken with my eDrometer. This varies with each Tilt/Brewometer and the Android and iOS apps allow you to compensate your readings. A little code addition would allow the same with my code. I prefer using the Tilt/Brewometer to show the trends, rather than using the data directly.

If anyone is interested in trying out the code, PM me.

If somebody develops a Linux application, I'd get one. Even better would be if it can be integrated with brewpi.

You mean like this?

I did the same thing with a RPi3 and a RPi2 with a bluetooth dongle.

I made a LAMP server, and store the results in a MySQL database and have a webpage to display the results.

I've been playing with my own version here, but it's strictly DIY.

Equipment and Software / TeensyNet Networked 1-wire controller
« on: April 04, 2014, 04:36:51 PM »
I've developed the TeensyNet networked 1-wire controller.

The TeensyNet can monitor / control up to 36 1-wire devices, including igital thermometers, switches, thermocouples, etc. Multiple TeensyNets can be connected to your local intranet and monitored / controlled by a web interface.

The hardware and software is entirely open source, so you can modify the TeensyNet system to suit your specific needs.

You can find more information at my website

Sounds intriguing. Got pics? I definitely be interested in this if the price was right. And being an electronics simpleton I'd need VERY specific instructions if it was a DIY project.

Added K-Type thermocoupler monitoring, and now have pre-made boards available.

Can be wired or wireless

Added a few new wrinkles:

I now have local or remote data logging and graphing.

I'm just about ready to post info on up to eight local LCD screens.

Pimp My System / Networked Temperature Controller

I've knocked together a Networked Temperature Controller using a Raspberry Pi, a Teensy 3.0 board, an Adafruit Pi Plate, and 1-wire devices that can be used to remotely monitor and control multiple devices. I plan on using this to monitor and control my beer storage coolers, fermentation chambers, and brewstand, but it could also be used for other uses such as brooder temperature control for avian breeders, sous vide, etc. You can see the complete write up at my TeensyPi website. Comments are welcome.

I've been working on a networked temperature monitor using the Arduino and DS18B20 sensors. I created the probes using standard telephone cord. You can see it here:
