You need to correct this error. 0.25/1.5 --> R2=0.1667 Ohm
I have been playing with this driver too. It needs very low value resistors to have high current output.
And you need to drive it with two 3.7V Li-Ion batteries. Here is more info about the driver, Driver Mod For up to 1.8amps with 2x 3.7v or 3.0v cells

DUDE If you read the thread i tested both drivers out.

Second it was Just a test i was doing and trying to figure out how they worked. I also mention in the thread that the negative is not continuous.

Finally i dint continue using them so i dint test any further.

You talk to fast.!

Keep trash talking.


I Dont like YOU.

There where several shots taking at me in that Post #5.

I Have zero respect for the slightest trash talking about me or anyone.

I never give out neg reps. In fact this was my second one i have ever given on LPF to None Spammers.!

I did not mentioned anything about the thread but was directly talking about post number 5# where you felt the need to try and little me like your mister know it all. Re read what you wrote. You must read fast too if you over looked the low blows that could have been left out of the post from the beginning.


Posting that we said for you not to discuss the circuit is false. Your a Liar. NO one ever said this.! Keep it up guy. Everything was to-wards post 5 and your trash talking.

Iam done here.

Oh and by the way Neg Rep'ing a member because they Neg you is frowned upon on this forum. If you Did something to deserve the neg Rep then Man up and take it.

Now that i see you abusing the Rep system and others will see this too, Your true colors are showing.

As For the comment you left in the Rep box is really making you look Really bad.

Doesn't answer emails.LOL I have right now near 7,000 in my PM messaging system that is after erasing like 3000-4000 messages because my box was full. I am know to respond to all my emails very fast. I just dont respond to people like you.

Saying i have a big month but yet your the one that was talking the trash. I guess i have a big mouth for calling you out.


Everyone know me as a fast PM responder. SO your only making yourself look Bad.

Reported.
