guys, many of you said that we are here to learn new things and share knowledge[/B]. i don't think we are bothered about [B]how people use the info we give. so why not appease the queries of the guys who wanted to know how the points system worked? :-)
Hi,
suppose we have a PCB with a lot of components in it; and we need to find the value of a fixed value resistor in it.
the problem is, any colour coding that was on this resistor has disappeared owing to wear 'n tear and we can't desolder the resistor from the board, as we can't modify the...
as u can c, pin1 of the device is grounded. so when the voltage at pin3 is positive, the output goes to +Vsat; 'n when the voltage at pin3 is negative, the output goes to -Vsat. thus, the sine wave at the input is converted to a square wave at the output of the op-amp (oh yes, the schmitt...
Hi,
Firstly, thanks for the time your spend on this thread.
Scenario at hand: I want to build a remote controlled toy-car: instead of a joystick in the remote, i need it to voice enabled. 6 predefined instructions (start, stop, front, back, left, right) from any of 2 persons only should be...
Hi all
What i could make out is as follows:
When the NMOS needs to pull down something or when the PMOS needs to pull up something, they can do so without Vds affecting the load.
ie, they can pass a strong 0/1 as the case may be.
But, when they try to do the reverse, some drop will be there in...
Re: Help needed: To understand SMPS mobile charger schematics.
Hi, I just simulated the ckt from your first post in multisim: 'n I'm getting zero output!!
But I made the following changes:
(i) Instead of 1n5819 I used 1n5822
(ii)I took the transistor as 2sc4341
Why do you think I got 0V across...
Re: Help needed: To understand SMPS mobile charger schematics.
Hi,
Many thanks for your post.
We are a bunch of college students doing our miniproject on making a mobile charger. Your diagram is a very good aid in our project.
Hope you can easily finish your work 'n post the whole...
