I love this circuit! It turns 5v in 12v at 1A max! This is awesome! And it's also variable! What's better? It has feedback so if you change load the output voltage will not change.
For this awesome circuit you need:
555 timer
Resistors
A small transistor like bc547 or 2n3904
A 10 mH inductor
A 70mohm or less n channel mosfet
Two capacitors (bigger is better)
An opamp (lm358 or 324 or 339 ecc.)
A potentiometer 10 to 100kohm
And some smaller capacitors.
