what is that MAR-8 driver

 Re: what is that MAR-8 driver

Some Basics in simple electronic.


This adj. resistor lead to ground.
A poti have even tree contacts.

In some circuits it's very important ,if the middle contact is not
soldered to one of the outer one,, so there's a infinity load to the circuit if the middle contact left from his path.
For example some dust on the way.

Some circuits die.

But not in this circuit

Re: what is that MAR-8 driver

just informte me that


the midle pin is coonected to the pin # 3 or not .....if yes they y ?

Re: what is that MAR-8 driver

right...

Re: what is that MAR-8 driver

from where i can get square wave out put as



10a & 12a closed ... 10c & 14c opened ----> square wave

10a & 12a closed ... 10c & 14c closed ----> sawtooth

Re: what is that MAR-8 driver

Close the bridge like written in the text. Or solder just one way.

Re: what is that MAR-8 driver

hi
i know u help all the people alot by your forum . help me i only facing problem with noise genrator /square wave gen...

can u plesae come put with working circuit ......so i can work on that may i need plesae .......


may i need 17v t0 23v noise also or just rich_6. modulate it with DV voltage

Re: what is that MAR-8 driver

what u think about 555 timer IC alos genrate square wave but

MX=18V

plesae come up with any idea

 Re: what is that MAR-8 driver

555 is also possible like MAX2206cp or MAX2008cp or
or CD4060 and hundret other ,but it's easyer to take my cicuit. So 741 op's
are one of the most used IC's over the world.

This evening im uploading a very detailed noise generator circuit.

Re: what is that MAR-8 driver

hi
i just make this 555 timer circuit . MAX voltage is 18V and in output coming 15V... is there any idea to get it 17 to 23

i can,t wait to see noise circiut........

i am uploading this 555 timer cricuit output is great square wave but 15V

Re: what is that MAR-8 driver

i have this pace 914 receiver .......is that work there is input of the wire that is coming from dish....

Re: what is that MAR-8 driver

hi friend here is i fine easy circuit with LM741 do u think it will work if i apply 17 to 20V
