CONCEPT
The idea of the project is to make a plug that allows to control different cooking appliances:
Immersion heaters, rice-cooker or electric plate and to maintain water at a precise temperature for a given time.
This project is for anyone who wants to cook according to the principles of sous-vide cooking:
in a bain-marie at a given temperature and time in dishes packaged in jars.
This project is trying to reduce what is needed to use this cooking technique.

HOW TO MAKE IT
The electronic board will be drawn on KiCad and produced using Easel on the CNC milling machine.
The components will be soldered
The relay and board will be mounted on a lasercut plate, designed on Fusion 360 and lasercut.
A 220V 5V transformer will be connected.
A screen and its I2C connector will be connected to the board.
The casing of the plug will be designed on Fusion 360 and 3D printed .
The front part will be lasercut .
A jack will be mounted on the case 3D printed .
A temperature sensor will be equipped with a male jack.

AKNOWLEDGEMENTS
When I started this program, I did not even have a laptop. It's a hell of a ride in just a few months.
58 years old.. it was a challenge to quickly learn such different things in areas I did not know.
It was pretty amazing....
This method of teaching and project management is hard and at the same time we dive in as in a cold water without knowing how to swim (yes yes Denis, another metaphor ...) And finally we swim more or better, better and better. The people around us influence us, help us to make almost anything and therefore to be almost anyone ... I feel pretty self-taught, with the fabacademy, I became a more hybrid person, more self-taught. I loved it..
Special thanks to Denis, my patient instructor, Wendy, my global evaluator, David who opened me to a whole new world, Nicolas for being my fabacademy twin , Axel for his help, Anne for her support, Romain, Adrien, Arnaud, Robin, Marie,Thomas, Quentin, Clara and Nathan, and finally Neil who has the ability to put himself at the level of anyone and teach him what he is able to receive.Thank you Neil.
Never too late to learn ...
