What kind of transistors are you using?

[myvideoisonutube]

@SirArghPirate Look at the end of the video. I tells you which ones to use. You probably can use regular 2n3904's & a 2n3906 instead.

[SirArghPirate]

@myvideoisonutube Thanks. But what are the differences between the different models of transistors?

[dpussy4u]

Hi couldn't see the values of the resistors clearly can you send me the schematic...I wanna try this circuit thanks...

[myvideoisonutube]

@dpussy4u From Left to Right: 33k, 100, 2.2k, 100k, 10k pot, 5.6k, 1k.

This circuit is excellent. You will like it.

for the 10mH inductor, did you purchase it with the 70 turns of 30 gauge wire or use the core and rewind it yourself?

[myvideoisonutube]

@BluecastProductions Made it myself with my Inductance meter.

[a2zhandi]

how would a guy scale this schematic up to boost 12V - say 50V ?

Thanks

[ElectrocutedMinds]

@a2zhandi idk

CAN U PLEASE TELL ME HOW CAN I GET 1 OF THIS INVERTER I REALLY NEED 1 --THANK YOU

me puedes pasar el dibujo del cicuito porfa??

[myvideoisonutube]

Don't own an oscilloscope. No clue about the ripple. All I know is that it powers all my 9V electronics just fine.

@myvideoisonutube

I recently bought an oscilloscope and checked the voltage output of this inverter. The scope displays a smooth DC output. No ripples or spikes. Maximum effective output is around 50ma for 9V devices. Higher current output at lower voltages.

[santiks]

what is the ripple? how many mV?

[usagold101]

link please

[myvideoisonutube]

No need for the link. Schematic is posted at the end of the video.
