Sous-vide cooking with the Wolfram Language and Raspberry Pi @Raspberry_pi #piday #raspberrypi
Earlier this week, The Raspberry Pi Foundation put up a guest post from Wolfram Research’s Allison Taylor. Taylor calls attention to the work of Diego Zviovich, who combined his knowledge of the Wolfram language and the raspberry pi to create his own high-functioning sous-vide cooker.
Diego Zviovich, another one of our ambitious power-users of Mathematica and the Wolfram Language on the Raspberry Pi, has managed to (affordably) master the science of sous-vide cooking!
For those who aren’t familiar, sous vide is a modern cooking practice where the food is first put into airtight bags and then cooked in a water bath at a very precise temperature. The result is perfect, evenly cooked meat or fish, with much greater penetration of flavours from any marinade you might be using. Actual sous-vide cookers cost hundreds (or thousands) of dollars to buy, but with a few sensors, a crock pot, and your Raspberry Pi with Mathematica installed, you can create your very own sous vide at a fraction of the price!
What you’ll need (along with your Raspberry Pi + Wolfram):
A 5V 2-relay control module An MCP3008 analog-to-digital converter 2 food probe thermocouples
The 5V 2-relay control module will be used to control the power to the crock pot. We’ll be automating this switch to turn on and off depending on our thermocouple readings, maintaining the appropriate constant temperature that we want. A walk-through for setting up a circuit and connecting the relay from your crock pot to your RPiPi can be found in this handy YouTube tutorial.
MCP3008 – 8-Channel 10-Bit ADC With SPI Interface: Need to add analog inputs? This chip will add 8 channels of 10-bit analog input to your microcontroller or microcomputer project. It’s super easy to use, and uses SPI so only 4 pins are required. We chose this chip as a great accompaniment to the Raspberry Pi computer, because its fun to have analog inputs but the Pi does not have an ADC. Read More
