“For a long time now I have wanted to own a SlowCooker. Unfortunately, I couldn’t decide on which one I should get. I like the expensive ones where you can set the temperature digital but, being Dutch, there is no way I’m spending that kind of money!
Now I have a little more time on my hands due to the COVID-19 crisis, I decided instead to just make one myself. I had this ceramic hot plate lying around which I was already using for my pot roasts. And after diving into my parts collection, I dicovered all I needed to buy was a 4 euro temperature sensor!
It is great for making stews and pot roasts, or tempering chocolate au bain marie!
Supplies:
Arduino Uno With Screw Terminal (Or any other type you have laying around)
DS18B20 TO-92 Thermometer - Waterproof with 1m cord
One 4,7KΩ resistor
I2C LCD Screen (I used a 16x2)
Small DC Power Supply (I used a Self Electronics SLT3-350IS-1 LED-driver)
5V Relay Module
Two-Way Momentary Switch
Power Socket with switch + Cable
Heating Element / (Ceramic) Hot Plate
Some PCB Board
Some form of housing for your SlowCooker”
