MiniMig EAGLE schematic & flying board
« on: July 01, 2008, 08:34:45 PM »
Hi everyone,

Got a couple of questions.
1. Does anyone have an EAGLE v4.16 / v5.10 schematic and/or board layout for the MiniMig. I have a schematic file... but I have no idea where from and nothing I have will open it :-? Could it be from a gEDA version or something... who knows.

2. I have a desire to build a small 'flying' board. What I mean by that I that it is a seperate thing like the "Gayle chip adapter" or "IDE-Fix Express Buffered IDE" that clips over another chip... However, there's no chip for it to clip over and I'd rather not put one there just for it to act as a mechanical bridge!
Instead I'd like to use the bare pads that are meant for the chip which would be moved onto the flying board.
I just need some way of doing the physical connection itself from the flying board to the original pads. Does anyone have any ideas?

I'm not going to say what I'm hoping to build because we all know what happens when anyone actually says they're going to do anything :-D Oh but I would hasten to say taht it will never be anything as useful as either of the two example I gave!!! :lol:

Ah well might as well put out any ideas I have had.

1. Mount the current chip in question, get another one and a socket and do it the usual way. This somewhat simplifies things... it's also quite wasteful and dovetails horribly with the idea of prototyping the design this way before making changes and ordering new pcbs.

2. Take a small cube of... wood, or something. Run metal pins up the side and put it in place as a dummy or standin "chip", then get a socket for the underside of the flying-board and proceed as planned. This is better in that it's less wasteful, and the design won't need to cope with disabling or ignoring whatever chip it's clipped over.

3. erm... I dunno that's why I'm here :-D

I've seen that one, its Zetr0 design isn't it.

I think I will try EAB as well, thanks rkauer.

Ah you may have misunderstood my use of those examples ;-) I simply listed them as "things which clip over existing chips" because I'd like to avoid saying what I actually want to do :-D

Would like to avoid this being one of those threads that sails off in 15 different directions with everyones different dreams of "what if xyz?!?!?!" and questions of "Why would you do that it's a stupid idea!" etc :-(

Just hoped for an answer or some ideas and then to get on with seeing if it can be done in peace.

It has been suggested via PMail that i could use ribbon cable which is currently the best sounding suggestion I've had.

YES! Exactly like that! :-D

Do you have the file(s) and would you mind sharing?

Cheers for that, I'm quite surprised there's no gschema to Eagle converter actually since gschema is open source and the ".sch" file itself is plain text.
