hey guys I have been given a piece of equipment to fix, that is not charging its battery. I am trying to map out its small circuit board to try and understand what it is thinking so i can figure out what isn't working.
I am having trouble tracking down the resistor network specs so I can draw...
Hey guys, I ordered some shottky diodes to speed up a transistor switching.
The diodes I ordered don't work for me; I will upload a waveform with the diode if it would help.
It was mentioned in the other thread HERE about needing a "signal" shottky as the ones used for power had a large...
Well after working with it and suggestions from here and elsewhere. This is where I ended up.
I have the frequency back up to 750 kHz which is where I wanted it to begin with (I had slowed it down by 4x earlier)
The key that I found to decreasing the fall time was from the 2N2222A datasheet...
From my understanding (someone stop me if I mess this up).
A motor is an armature that spins because an electric current is applied to it.
A Generator is an armature that generates an electric current because it is spinning.
But they are physically almost the same.
However as the motor...
Hey guys I am playing with my new oscilloscope i got myself with income tax, and ran into a puzzling question.
I am trying to generate an inverted pulse signal, and while my transistor is saturating quickly (driving the output to ground), when i turn the input signal off, it takes its sweet...
I think you are over complicating things for yourself
a) displacement of engine in interval between 3 and 5 seconds
this is just asking how far it moved in this time, find its position at 3 seconds, find its position at 5 seconds, subtract where it was from where it is to get the...
ok bear with me, and stop me if I've messed something up here (very possible)
I am assuming a few things here, because i never got an answer.
1.The angle of force that the vertical load is compared to is the angle of the rigid arm

2.The force...
in experimenting with something like this a while back (mine was ping pong balls in tubes)
the ball will try to rise at some relatively slow speed, based on the buoyancy of the ball and the orifice formed between the ball and the side walls of the tube. the tighter the size of the ball to the...
I'm not sure i know enough to know how to ask my question, but here goes.
I want to figure out how the force pushing up on a pivot gets transferred to a cylinder also pushing on that pivot, for lack of better description, here are pictures of kinda what I am asking, the numbers are more for...
