Re: [time-nuts] FE5680A x-rays
That is a great job. Just looking at the TIFFs. Motivates me to get the better viewers mentioned in the thread. Funny thing. I always though having an xray like this would be quite a help. It reveals the jobs just that much harder. But still fantastic. Regards Paul WB8TSL On Wed, Mar 28, 2012 at 2:54 PM, Rich msima...@sympatico.ca wrote: Nice job. I downloaded them for reference.

Re: [time-nuts] FE5680A x-rays
Rich: Thanks for your work, nice images. One problem I see in the composite image is that it seems you opened the raw files in the wrong mode, and what was 12-bit raw was reduced to only 4 bits (16 gray levels). I reopened all from the raw (in 16-vit mac order), combined them with soft blending and created much nicer composites. There were some compromises done in blending adjacent images with tall components, due to perspective, but overall traces can be followed. I don't know if this list has a repository, or what's the accepted practice on sharing files here, so for now they are available on Google Docs (double zipped so GD doesn't screw up the images): https://docs.google.com/open?id=0B18H4W8aZSP8SVhuLUl0RG1UdnFpUlJ1WHdmeF94Zw There are four images, full size and quarter size, jpeg and tiff. It would be nice if it was added to other FE5680A repositories. I cannot guarantee it will stay long on that Google Docs account.

Re: [time-nuts] FE5680A x-rays
Ok here they are: About 30 real-time X-ray images were done in transmission and the images were captured using the imaging system, printed and later assembled to create a one meter scale of the printed circuit board. A low voltage, in the 50kV range, was used to better visualise the hidden copper traces. In the attached file the two directories in Data are one: image format in raw (need to be flipped and rotated as needed if you want to look up or down at the pc board) and two: in the psd Photoshop format. They can be converted to jpg with a slight loss of resolution by many software packages, if desired. Two other files, in the top level, are for guidance in positioning them on the chart and a look at the final assembly result (at much lower resolution). The images are available at: http://download.muanalysis.com/FE-5680A.zip EnjoY I am happy as my unit is now working correctly. It was an e-bay bargain if you don't count the debug time!!! Hope this info will be useful to others. ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

Re: [time-nuts] FE5680A x-rays
Rich, Would it not be better to make them a TIFF format ? While larger in size, there would be no loss of resolution. BillWB6BNQ Rich wrote: Photoshop works with both the RAW and the PSD format.

Re: [time-nuts] FE5680A x-rays
@Joe: I'll post a link of the 25 high res x-rays of the FE-5680A board on the company website. Gimmie a few days and I'll post the link... Also in assembling my composite image I also included in the middle a schematic and an optical layout taken from these three websites for guidance: General information and a collection: http://www.ko4bb.com/dokuwiki/doku.php?id=precision_timing:fe5680a_faq The partial schematics and photos can be found at: http://comments.gmane.org/gmane.comp.time.nuts/17630 This is the schematic pasted in the middle of my x-ray composite. Bottom picture was taken from: http://www.vk3um.com/Reference%20Data/Fe-5680A2%20VK4XV.pdf Just beginning to realize the amount of work many people have already put in understanding these neat units.
