look post #31

I have finished reading all those articles..I also watched that video clip.It really works well.

If it works correctly and my device doesn't what could be the problem?

The passing of these devices over the years is a topic that many people talk about from time to time.. I think the best solution for this is to accurately record the way it is made, part by part, in one place. I think this problem will be solved if everything can be seen in one place very precisely

Let start with this = what is the range for cola can ?

For me detection of the can got to around 55-60cm at max, i tried bigger objects and it goes higher. Also today i tried a big coil of 1m and it goes around 3 meters for a round tray 45cm in diameter i got from the kitchen but i couldn't find any metal-free place in the house to test it for sure also it consumes battery and gets the mosfet hot maybe it's not the right measures i made the coil a while ago with a 0.7 wire ( the plastic one with few wires inside it i'll try to find picture of it to attach.
and sorry for the late reply.

what could be the problem?

show oscilloscope pictures on both sides of R6.

you can NOT test 1 meter coil in your house. leave this attempt out. i wrote this very much times.

yes brother that's true, i think i'm gonna make a new one probably with ethernet cable anyway, i'll post here how it goes

[kt315]

this cable has lowest layer of (polyvinyl chloride?) insulation on wires. BAD. DP works with big FIRST DELAY but you have to think about how to do the coil better.
you must always think about the Quality factor, Q-factor in first order doing L. it is mean FAT insulation on wires or air gap between every turn of wires in the general winding. if you may do that.
please learn electronics basic course BEFORE to begin something.

I am really happy that you are willing to answer my problem my friend...

So How can I get help from you?

I am attaching below the pcb layout I got to make this device..please tell me if it is correct..I think from there I can successfully solve my problems with you.

Yes sir this is absolutely correct actually i have this exact photo from your older post because it was easier to trace the lines with.
and let me know what i can do if i should drop email or fb if you wanna give it some trying off the forum i'd be glad to assist...or at least try.

Iam not sure if you're talking about the 0.7 wire i talked about before or the ethernet cable but ive heard cat5e cat6e if they are good quality and not chinese garbage they work good, i have made a coil that's a little bit bigger and iam testing it it works better so far but the machine is complex to tweak and get it right so I'm still adjusting and gonna try different ics soon and hopefully it improves.

I think it is not wrong to indicate the email address here. I don't know if it is allowed to present such a thing here..
I have sent you a private message with my email address. through it I will give you my fb profile

Again I thank you for your humble response
