May 28, 200521 yr HelloI am currently struggling to print the image files for the FS Bus PCBs (old style.....PIC).I have been using the PDFs on Jari's sire (http://mikkila.wabbits.org/fsbus/doc/pdf_e.php)The problem is, I am using the Print n Peel Blue paper to make my PCBs...So I need to flip these images over...Adobe Acrobat wont let me do that!If i copy it out as an image file, and then print, I lose the quality of the line (ie, they need to be printed PERFECT for the trakcs to come out right....)Anyone got any ideas? Ideally I'd like to also have a few PCBs on one printed page (COM, FS KEY, Display Controller, FS LEd etc), as the blue Print n Peel sheets are letter size (almost A4).Anyone have any ideas?
May 29, 200521 yr the best thing to do is goto the main site (http://www.fsbus.de) and download the .LAY files which can be found in the download sections, use this free viewer to print them, http://www.abacom-online.de/uk/html/sprint-layout.html.just remember Dirk is updating all the boards so currently there are only the interface and 7 segment display boards.
May 29, 200521 yr Thanks mate....I am going to make the FSBUS Classic cards (the older PIC type ones)....as they seem to be "proven" and work well by all accounts :).
May 29, 200521 yr I have made all of my boards using the photo-etch method and I am VERY pleased with it. It does require buying the more expensive blank boards (presensitized), having a good light source (100 watt bulb), developer, ferric chloride (for etching), and transparency film for an inkjet printer. All of the chemicals can be gotten at www.circuitspecialists.com. I have yet to have an etched board come out bad. If you are to choose this method of making your own boards, I will be happy to answer any of your questions. Milt
May 29, 200521 yr I too started out with the press and peel paper to do my boards. Had a great deal of difficulty getting the image to adhere properly to the copper. In the end, was unable to get a useful circuit. Switched over the the positive resist boards and it worked sweet. A lot less problematic than the paper.My finding is that if you are trying too hard to save money on this project, it will cost you more!!! I took the PS files to a printshop, any decent photoshop program will open them, and had transparencies made. Got an 18" blacklight flourescent tube, put it in a box with a piece of glass over it. Worked in my basement with no direct light in the area (still plenty bright enough to see), put the transparency down, peeled the covering off of the board. Placed it on the print, turned the light on for about a minute and then into the developer. Works great, but I got the smallest boards I could find and did display boards for testing. Didn't want to try a keycard first.

Its a shame the toner when removed smudges and makes the PCB material dirty!Some of the traces are very thin and got broken during etching, so I shall buy a conductive pen (I recall seeing these for sale)....the Press N Peel is good, I think if i were to do it again, I'd use photo-sensitive though....(or was that IOCards? ;))
