Using a power supply allows the circuit to use as much current as it wants, to operate. Which can fool you into thinking that a cell at that volts will work also. A battery (cell) at 0.6 volts usually has built up too much internal resistance to light the led.
Great so what lower limit voltage can this run at ? What would the maximum power delivery be. Could it run a tazer module that only requires 0.05 watts ? At the moment I can use a dead aaa battery to run a small flouro from a tazer module but not below 0.65 volts . Sometimes it only 0.02 watt
@@Buzzhumma You can use any high amplification transistor (in this case it's a NPN, you'd have to change the circuit for an PNP). I have used big darlington transistors. I think the biggest limit is the flyback voltage into the base and you need to keep the emitter to base voltage spikes to below the max (about 6 volts for most mfgs).
What value H inductance coil would be optimal to use as I would like to build this circuit and I want to purchase some surface Mount ones and want to buy some of the correct value, so what would be a good range to shoot for like low side 6.8mH or 100H range or what are you 🤔 thinking?

Very very cool. I'm thinking inductance size will determine amps, but low low milliamp situations could greatly benefit from this!
If u don't mind i just wanba know if k2996 mosfet works for that operation. Thank you
I have never tried it. I will put it on my list.
Hi, How long could this setup with SMD type as substitute for a torroid coil?

It depends on your design. I have run a 70v neon buld on one of these using a toroid buy changing the windings.
@@tsbrownie is it limited by the transistors lowest voltage? 2n222
I looked up data sheet but I can't see what the lowest forward voltage is .

One use smd and another use ordinary inductor... same thing
SMD is smaller and more efficient.
@@tsbrownie yes i know
@@Elarpachuau So not the same.
