The heart of the device that [Kerry] designed is based on 6 power MOSFETs, a few operational amplifiers ... the latter allows a constant power load mode (as power = current * voltage).

He includes two interesting demos. One is that by attaching the flickering LED to a BJT he can turn it into a current amplifier and successfully drive a much more powerful 1W LED with the same effect.

Typically, pulse width modulated amplifiers are used to emulate linear constant voltage amplifiers or linear constant current amplifiers. PWM amplifier chips consume less power than these linear ...
