Please tell me if I can improve this circuit?

Update: I think I did it!!! There is now full voltage going through the “motors” at the bottom.

Getting there.... now for proper power to the bulbs

The current setup may work, but there isn’t enough current due to the pulses being connected directly to the mosfet gates. How to do it?...

The timings not quite right, you can adjust the mos specs to get a bit more power from them.

Thanks Billy. I was hoping you’d come around

But what about the logic train connected directly to the gate of the MOSFET? Wouldn’t it restrict the current flow of drain to source? From what I’ve learnt (correct me if I’m wrong) is the MOSFETs current is directly proportional to the voltage applied at the gate. The logic train will be an Arduino in real life here... it doesn’t output a big voltage.

When you say the timing is not quite right, do you mean by a smidgen or a whole bunch?

Timing was out by a smidgen, that seems to be correct now. And as far as the Fet drivers, you may have too use transistor amps as done for the top Fets.

Shot Billy. I’m just trying to figure out the n channel mosfet and transistor pair.... If I connect the logic train to the base of the transistor and the emitter of the transistor to the gate of the FET, the FET doesn’t get “Ground” to stop the current flow.

i made some futher changes to the mosfets and how the driver BJTbis made, check this http://everycircuit.com/circuit/4969199649947648

Hurz. Ok cool. I’ll check it out. Wish the iPhone app supported links to other circuits
