When pressure canning, food is usually held at temperatures up to 120 degrees. Some recipes use lower temperatures, so it is very important to pick a DS18B20 sensor that can work at that temperature. According…
Distillation and rectification involve heat, hot liquids, flammable vapors and electricity. An assembly mistake, a cooling failure or a blocked vapor line can lead to burns, fire and destruction of the apparatus. Automation helps detect…
How to enable Lua in the Samovar, which functions and variables are available from a script, and how the architecture works: init.lua → script.lua + a mode script.
To control cooling, Samovar can use automatic water supply, regulating the flow of water fed to the dephlegmator. The pump output is controlled with PWM. A PID controller is used to hold the set water…
Below is one way to set up remote access to Samovar. All the settings can be done in a couple of minutes.
Beer mode in Samovar: the line-based program, eight step types, mashing methods (infusion, decoction, HI/HERMS/RIMS) and recipe import from BeerXML.
The purpose of the ESP32 pins is described. See the article for details.
Below you can see an example of the log from which Samovar builds its charts. You can hide any data series by clicking its line in the legend (at the bottom), for example the Boiler…
Before you start, make sure you have the current version of Arduino IDE installed. To install the ESP32 board in Arduino IDE, you need to go through a few steps: In Arduino IDE, open the “Preferences” window. To do this,…
A Samovar take-off program is a text set of commands that describes the controller’s behavior over time. Each line specifies a condition (sensor temperature, time, volume), an action (turn the pump on/off, change the speed,…
