MOSFET to act as a gate to switch the power to heating element on and off.

There are many choices, as long as the current rating and voltage rating are high enough.

My source is Sayal Electronic store. sayal.com. They are not the cheapest but is more convenience for me.

 

 

One capacitor required. The Farad rating will affect the frequency of the 555 timer.

I use 47uF.

 

 

This is a typical 555 timer from Sayal Electronics.

You will also need a variable resistor. I use a 5k ohm variable resistor.
