Well... I was bored today, so what the heck.




I don't have any surface-mount IDC pins, but I can at least attest to the fact that continuity is good, so the vias worked... egads, DIY vias suck :S

You can get PCB's quicker, but it costs more. I went with batch PCB service since I only wanted 3 for prototypes, which is why it takes so long. If you want one sooner, I can try to etch one myself... I've been meaning to try a 2-layer board for awhile now...

I just placed an order for prototype PCB's, should take a month or so to get them. By then, I should have the Samtec -01 samples and some surface-mount IDC headers as well, so I should be able to assemble the prototypes as soon as the boards arrive.

We were originally talking about creating a hardware serial debugger that communicated through the controller port. Then, when I came across a connector compatible with the expansion port, we got sidetracked. Eventually, the idea is to take the hardware debugger idea and use the expansion port inste...

Continuity looks good, but hold off ordering any more connectors for now, I want to get a sample of the -01 thickness to compare. The -02 makes a good solid connection, so don't worry about the ones you've already ordered, but I think the -01 might be a better fit. Also, I have calipers, so I can me...

I know of a good place to get prototype PCB's in low quantities (1-3), so how about this: I'll go ahead and order myself the parts to build one, and once I'm happy with it, I'll send it to you so you can test it out and see if you're happy with the design. At that point, once we're both satisfied, t...

Actually, if I use surface-mount IDC pins, I can alleviate the board-propping issue by fitting the entire board inside the recess created by the removable cover. That should be much more reliable, but it requires a 2-layer board (which isn't a problem, I just can't reliably etch one myself...). Some...

The only issue I see with this connector is, as I said before, it isn't very deep. You can kind of see by the photo, but the PCB kind of goes into the port at an angle because the slot isn't deep enough to go in flush. I'm not sure if that will affect the connection. I would suggest using surface mo...

Third time's the charm.

The site isn't sold out, Samtec parts just tend to not be stocked by wholesalers like AVNET and DigiKey. They don't sell enough of them to keep them in stock, but you can still order them and it just takes a couple extra days for them to get the parts from Samtec and then send them on to you. The -0...

I got the Samtec headers in today, and after a bit of Dremeling, it fits beautifully. The part number is MEC2-30(/40/50)-02-L-DV. AVNET sells them for $5. My offer to assemble and send you one still stands, once I get around to dragging my etching materials out again... http://avnetexpress.avnet.com...

Emulating a system crashing hardware glitch... that sounds like all sorts of fun >.<

I've updated your library with some changes: * Set the numbers in the "gold fingers" to Top and Bottom layer, so you can read properly the numbers when hiding one of the layers. That was intentional, silkscreen on the bottom layer is supposed to be mirrored. You shouldn't put bottom-layer...

Ok, so I finally got one of these working on a HiROM board ( SHVC-1J3M-11 , to be specific), so I do now have the ability to run my own code, so long as it's HiROM. I build a LoROM board as well ( SHVC-1A3M-30 ), but I can't get it to boot. I have a 3rd working FlashROM, but I don't have another don...
