The gate driver circuit shown in the screenshot uses BC547s, which are limited to less than 200 mA current. Instead, if the two transistors were BC337 or PN2222A which can easily handle over 500 mA, they could charge and discharge the gate faster, and thus reduce the dissipation in the MOSFET.

2012-04-29 Ring Oscillator Teleport Transponder
I’ve built and blogged a ring oscillator that works good for making LEDs look like marching lights on a marquee. I think I could get 9 LEDs, the circuit and a 9V battery into an Altoids tin, and it would look cool. I’d have to paint over the ‘Curiously..’ whatever on the outside, though. The
