Hello...
Before starting to do this circuit There´s something i must know!!

I want to place this circuit in a power suply which goes from 0 to 20V
......and i was wondering if it this circuit displays the voltage with two decimals or only one.....(when you are using the R3 for measure from 0 to 20 v obviously)......
I hope it uses two decimals because if not I will have to find anotehr circuit....
I imagine you already notice that my english is terrible....that's because 0m from Argentina.....so.....sorry for my english...

Thanks....Chau!!..Saludos desde Argentina

Hello, i´m from Brazil.

When measuring from 0-20V, this circuit displays 2 decimals.

Hi all,
Where can I get the "EXACT" PCB pattern layout for this project? I tried to used the layout in this post but everytime I print it out it's always oversized..
I set my printer to 1:1 but to no avail..

It is written in the article that you must set your printing software to resize the layout to 35% of the original size, or use the dimensions in milimeters that are under the picture on the article.

It works perfectly.

Regards

Hello! Thanks for you reply.
I read Billy´s corrections, but I still do not know if its a TrimPot or a Trimmer, and I don´t know where the C6 and C7 goes.
It would be nice to make the corrections on the main site of the project, because I linked that site to many friends that looked for this circuit.

I´m getting this program you said, but where can I found the schematic? Thanks again and contratulations for the great site!

Regards.

By the way, there are some differences between the scheme and the PCB photo-layout

Is P1 a TrimPot, like the scheme says, or a Trimmer, as the photo and article describes?
Is the ICL34 pin correct in the scheme? Going out to the Display?
Where are the C6 and C7 on the scheme? They are not there, just in the PCB layout you can find and try to discover...

Finally, if someone corrected the scheme, I would apreciate to see it.

p.s.: I tryed to assembly it on the ProtoBoard (breadboard?).

Thanks very much,
Regards.
