Designing a homemade electric lighter

I'm trying to make an electric lighter ( like this https://imgur.com/a/wg8q7) using the framework of this guide.
https://www.instructables.com/id/Make-a-battery-powered-soldering-iron/?ALLSTEPS
except mine will have a few more feature and the soldering tip will be replaced with nichrome most likely.

Theres is just a few things that I am stuck on

-First, Is nichrome the best material to use as the heating element?
Assuming we do use a wire heating element the length of the wire will be 1.5-2 inches long, what would be the best gauge? any other details about it?

-Second, I need the heating element to stay at a constant temp of at least 500 Fahrenheit
What type of circuitry would I need to accomplish this, what if i wanted to to be able to control the amount of power?

-Third, what would be the best batteries to use for this? I was hoping to be able to use 4xAAA or 3AA

1) nichrome would be my first choice, use ohms law
2) pwm (555 timer, pic)
3) yep
that is still on my to-do list

thanks joe

Can you help me use figure out ohms law? Total noob here.
If i were to use 3AA batteries what would be the voltage and power supplied?

say, (1.3V per battery*3) / .5A
3.9V/.5Amps=7.8 ohms

Volts/Resistance=Amps
Volts/Amps=Resistance

Ok at least i have to place to start lol

Where did you get the .5A?

.5 amp was just a random number

welp, alright.

Do you mind telling me how would you go about building this?

Imagine my surprise....
There is a calculator for it!
