There are links to buy 3d-printed carriers from your choice of a few different professional 3d-printing services, and bare boards, and components to populate the boards, and directions how to put it all together here:
http://tandy.wiki/REX Specifically in "Build Your Own REX" Three links right near the top. BUT, that requires some non-trivial soldering. This is basically how to buy all the parts and make them yourself. I don't know if anyone is currently offering to build this version for sale. It's a pretty recent development. But I have built several for myself so I know they work, mechanically, electrically, and software. A standard original REX1 can be sanded down to fit in this carrier, including the chamfer. Just sand all 4 edges equally until it is 16mm x 38.2mm, and then sand the chamfer corner by eye until it fits.(1.9x1.9mm) This will just graze the edge of 3 of the jtag through-holes, and the TP1 & TP2 through-holes, and the chamfer will eat into TP2 a little more than just grazing. Most likely you will never actually use any of those connections anyway, but all those connections remain usable, even TP2. The sanding doesn't break anything. The sanding kisses the edges of some of the through-holes, and actually gets into one hole a little, but does not come near any of the traces that connect to those through holes, and the most aggressively cut one TP2 isn't cut enough to prevent using it physically (soldering a wire or a pin header to it) So if you have a regular REX, you can just buy a pcb2molex8878 carrier from Shapeways or Sculpteo, and sand your rex down until it fits. http://shpws.me/RqW3 Be careful to do it evenly though, so that the castellated edge contacts stay centered and aligned with the pins in the socket. Sand the jtag end a little, then the TP1/TP2 end a little, switching back & forth so you don't end up sanding one end more than the other. Worst case, you can get away with making the board shorter than 38.2mmand it will just be a little loose in the carrier, but should still be trapped by the retainer wedges. If the pcb is shorter than the holder, then it will just self-center on the pins when you insert the carrier into the socket. I would sand by hand only. Lay 120-160grit paper down on a flat surface and run the rex on the paper. (rather than say, filing on the rex or trying to use a sanding block or even worse a grinder or belt sander etc. Flip the rex around in your hand frequently to avoid going off-square. Here is a mock-up. This is an original REX1 pcb with the edge.cut dimensions changed to what I said above, to emulate the sanding. top http://tandy.wiki/File:REX1_pcb2molex8878_sanded_1.png bottom http://tandy.wiki/File:REX1_pcb2molex8878_sanded_2.png ---- There is a version of the carrier that doesn't have the chamfer, but now that I see that you can actually sand the chamfer into an original REX without killing it, and you would still have to sand the ends and sides down the same way anyway, I don't see much point in it, except for some other pcb not a REX1. http://shpws.me/RuGh (I keep saying "REX1" because Steve has made other versions REX2, REX3 etc which are totally different.) -- bkw On Fri, Sep 27, 2019, 23:36 Fred Whitaker <rr...@hotmail.com> wrote: > I would like the new REX boards.
