AI Thread Summary
The discussion revolves around verifying the connections of integrated circuits (ICs) in a project involving a breadboard setup. The user is concerned about whether their IC connections align with the pinout diagrams, specifically for the CA3130 and NE555 Timer. After troubleshooting, it was determined that removing a capacitor improved circuit functionality. Participants emphasized the importance of understanding the circuit's intended function and ensuring correct connections based on datasheets. The user confirmed that the circuit is now operational after making adjustments.

connectiong IC in a circuit ??

I am working on a project ,

[PLAIN]http://www.2electronic.com/wp-content/uploads/2010/03/cellphone-detector.jpg

i have done everything right but nothing is happening when i am running this project on breadboard,
i have connected IC in the same way as it is defined in above circuit,

[URL]http://circuits.datasheetdir.com/28/CA3130-pinout.jpg[/URL]

1 and 8 of IC is connected to the Capacitor 6 and 2 is connected to the resistor and so on,
i want to know that the IC connection defined in the circit is same as it pin out diagram ??
i mean,
in the pin out diagram 1 is OFFSET Null and 8 is Strobe, i have connected capacitor in 1 and 8 , am i doing correct ??and for the NE555 Timer, i made the connections as defined in the circuit...
is the connections are ok comparing with its pin out diagram ?
because in pin out diagram 1 is GND and in the ciruict 1 is grounded

if i am giving the same connetion in my breadboard as in cirucuit will my circuit work ?

What is it supposed to do?

The input is bypassed with a 0.22uF capacitor and the opamp is operating at very high gain, so it would have minimum bandwidth and very little sensitivity.

The antenna suggests a UHF signal, but the receiver has no chance of working at UHF.

At least remove C3.
 


thanks alot...cirucuit is working now :)

you have created 2 treads on this project, in both of the you were asked what is the cct supposed to do ?
we are all still waiting for your response :)

my other thread is different from this thread, i read the datasheet of both ICs and understands the connections :)
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
Thread 'Beauty of old electrical and measuring things, etc.'
Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
