  • Duty Cycle.

    Your wattage needs to be time sliced properly. The square wave is easy, but the charge curve off the BEMF presents more of a challenge in your comparison calcs.

  • Your power measurement is wrong. You are using an equation for DC and your current/voltage across your resistor is NOT DC.  You need to work on building a circuit to properly measure power.

  • The input is pulsed DC, the output is that pulsed DC and BEMF bridged to DC. The first resistor is on the Battery the second on the bridge. The resistors only see DC as the electron only flows one way through both resistors. Perhaps I did not explain that part well enough, sorry for any confusion.

  • Did I miss something ?

    What is the other end of the green wire connected to ?

    (The one which is croc-clipped to the diode).

  • thanks for sharing, this is important as Steve gave up

  • What voltage is that DC supply?

  • 9 Volt rechargable battery.

  • dude! if you connect a 555 timer for PWM and a MOV damper to audio transistor and ignition coil with primary connected directly to battery and connected to square wave output with blocking diodes to 555 to protect it from the recharging battery when operating at resonant frequency you can also step down the output and use it to charge the battery as well with this setup oter things can be hooked up to the battery in parrallel free energy!
