Superscan PI

[GeoMax]

Hi Carl,

thanky very much for the explanation!

Hi ZOUJiarui,

why do you want to make the SuperScan? What things you want to detect with it? And which technical feature of the SuperScan is the reason why you want to build the detector?

I'm fascinated by its depth.
thanks

I checked the capacitor and there was nothing wrong with it. I went through many copies of it, or photos of the original circuit, and they were almost identical.

[ZOUjiarui]

Unfortunately, I didn't fiUnfortunately, I can't find any pictures of the circuit board that can be used for reverse engineering. What I can use is the only information that is circulating on the Internet.
I think I may have almost finished the circuit, but I should have burned out a few places during the test to cause it not to have the proper voltage.

I'd like to get a new PCB for testing
Install the power circuit on the right side of the PCB until it works properly。But it still needs to wait, and money limits the speed at which I can make it.

Can Mr. Eric Foster come out and give me some hints?
Thanks a lot.
It's hard, but I still don't want to give up.

Hi ZOUJiarui,

there is a SuperScan PCB in the Internet. Someone made one. See picture. But I do not have information who made it and where you can buy it. Maybe someone from the forum knows more about it.

Thank you
I know there is a modified version of superscan pi called rospy deep scan in the forum, but there is no schematic.I like the original super scan pi better than the modified version.I've already made it, and it would be a shame if I couldn't.

Hi ZOUJiarui,

this circuit is also a mess... One look at it and I saw already 4..5 errors. Based on the ciruit diagram sema.pdf, the detector can not work propper.

I think the hand-drawn drawing is correct. It has the same power supply as the gold scan2 sketch that Eric posted on the forum

One thing that can mess this project up is the transistors. Eric's detector designs, in many cases used transistors with ECB pin configurations. Where as most common transistors use EBC. This fact gets lost in the redraws and various pcb remakes

So in one pcb image in post #151 I see BC214(EBC) and BC184(ECB) with labels in red BC640(ECB) and BC639(ECB). This pcb uses ECB transistors. BC214, 2N3906 and 2N3904 will fail on this pcb

In your pcb image post #176 you have these labeld 2N3906 and 2N3904 and appears to wired correctly. This pcb uses EBC transistors. BC640(ECB), BC639(ECB) and BC184(ECB) will not work on this board

Which transistors are you using in your circuit?

This section of the circuit generates your +5 volts, if not working correctly, nothing works

Is this the redrawn schematic of what you have built? Why are there no component labels (R1, R2, C1, C2, etc)? Why is ground shown as +24V? Why are there 10mH inductors all over the place?
