Apologies to Rudi!

I had taken the X out of the X-Calibre. I had seen the X and never realized it was a design element...I didn't see the forest for the trees.

Below are the 1 Layer and 2 Layer versions that are closer to Rudi's intention.

Default Boards

I would love to get my hands on a board for this. As far as I can tell, none have been made. Does anyone plan on making a run?

There were boards made locally (in South Africa) for our consumption. Unfortunately its a bit silly to send boards from here so you on your own there. Quite a few were built, so the design is sound. (I've still not assembled mine though )

Cheers

Gert

I just can't justify making a run myself. It would take too much time and effort for only grief. Look at all the hassle others have gone through when they try to be altruistic.

The amount I would have to charge for boards to overcome the Pain-in-the *** factor would make them uneconomical.

The files I posted SHOULD be adequate for someone interested in producing a few boards for personal use. The issue is that without a lot of boards being produced, the price skyrockets. When I submitted the boards to BatchPCB.com the price (without shipping) was $55 per board. Expensive on a per board basis, but a bargain for such a small production run.

Just for full disclosure, I haven't produced these boards yet. Time will only tell if I will.

If someone posts a PDF I will photo-etch one for you.

I can import it into DipTrace, but the files aren't fully RS274X compliant, so the board ends up being ginormous.

These are the pdf's created by Advanced Circuits freedfm.com.

I included the silkscreen and drill patterns as well. I hope this helps.
