Parts needed :

Arduino board - approximately $20
Integrated 8 digits led display with MAX7219 control module (3 wire interface) - $5
Pushbutton x 2
Piezo buzzer - $3 (optional)
Waterproof DS18B20 Digital temperature sensor - $10
4.7K ohm resistor
5V Relay module for Arduino, capable to drive AC125/250V at 10A - $4
Rice Cooker
A wood board, plastic box and silicone sealant for protection of the high current part of the circuit
You'll be set for approximately $40, maybe even less. That's not counting the rice cooker, but you probably have one kicking around or they can easily be found second hand.
