[PCB too large!]

Ok I thought the text has to be readable, if not the PCB has the wrong size.

Ok thanks I try the PCB you postet me in a word file. Thanks!

Greetings Benny

Thanks logan!

I would make my PCB today and write back if it worked and if I could beginn with building my power supply!

But first I have a questions:
1. In the Word-File, you send me, there is the text "Electronic 2002" and the internet adress, but this text is very unsharp. Is that ok? I mean why is there a text that nobody can read if the PCB are maked.

Greets, Benny!

Hello!

If I do this is I got the new size: 12,5 cm and 8,9 cm, but it hast to be 12,5 to 8,7 cm!

There is also a white border and I don't know if I have to remove this first and then stretch the picture.

Thanks a lot!

Greets, Benny.

Hey everybody!

I have a problem. I want build the 30V Power Suplly, you can find here: http://www.electronics-lab.com/projects/power/003/index.html

I downloaded the PCB in GIF Format. Now I want to print the PCB but ist too large. How can I resize it to the right size?

Thanks, Benny!

Hi

I thought I have to use a 0.47 Ohm couse I think ist must be exact that value that the current limmiter can work correct.

Is this not so? Well if not then I would find some right resistors.

OK thanks I will see who I would handle this.

But I think I will not even need 3A. I have no project that needs so much current.

Hi

Thanks! Now a question: By my shop there is no 10W 0,47Ohm resistor only a 5W. The Toleranz is 10% is this to much, or is this normal?

I will use the piower suplly not often at 3A Current, so can I use a 5W resistor, or would he to warm?

Hello all!

First I want to tell something about me. This is the first english forum who I registered because I'm German. So my English would not be perfect but I hope everyone knows at least the meaning. I'm 17 and learning a job as electronician and do electronic long times in my spare time for years ago.

So let me start... I wanted to build the Power Supply as I found the PCB and Schematic and I would use the parts that I found on the project page, but then I looked in the forum and there (it seemst to me) exists some problems.

I read that some peaple changed the 0.47 Ohm resistor in a 10W exemplar. The changes also some other resistors becouse the got very hot. Also some Opamps some people changed. Also the transformer seems a bit undersized (I read that, too).

My Problem is that I no a little confussed what change is good/bad necessary or bullshit. So I ask you what changes have I to make that the current limiter works perfect and all the other things works good?

Sorry to ask you but the treat is so long and haves about 52 pages and so I have no chance to read all the godd stuffs and read cfhanges that be made, but who worked not well. I'm not an english expert and I understnad not every post so I asked you here to help me.

So thanks for reading and thanks for posting in forward.
