you would need to edit the librarys, that would be easy.
I guess there is a Braille-font for windows?
you can choose the font and size used for the text near the components.
it is required for each part individually, but it is only one-time work.
If you could get a plotter or cnc to print some embossed image in
paper.....
i just tried if the dxf export works, it does fine i orcad 9.2.
it is not far from DXF to a .PLT or a file for a CNC.
The "swelling paper" has alcohol in the microcapsules, right?
this is most likely why it works in a inkjet - some have alcohol containing
colors. maybe it doesn't even need to break open the microcapsules, maybe
the alcohol in the ink itself makes it swell?
have you tried plotting with alcohol?
it would be easy on paper.
It would also be no problem at all to fit a "hot pen" to a plotter.
a 12v miniature soldering iron (dollar store) is bound to work fine.
it would be more than light enough for a simple plotter.
I only have seen the image of the drawing on this page, i have no idea how
narrow
resolution you could get with swelling paper if the tip is small enough.
definitely interesting topic...
Also look at the netlist files.
I have a hard time imagining that all, but i had the following thought:
if one can't see the schematic, but feel it on the paper, he has to make
a kind of picture of it in the head, right?
I guess it's somehow like "tracing the wires and remembering them".
Well, for a simple circuit, it might be even easier to just read the
connections
of a netlist.
Don't know if this is anything to follow further...
I think it depends a lot on what you want to do with the schematics then.
(e.g. i know one who always enters the netlist for pspice simulation.
he has learned this somewhere in the far past and is much faster than with
drawing
the schematic.)
I myself like to work without a schematic (on paper).
I do this much less since i have fast and easy pcb making process.
(it is less work to make the pcb than do it on a veroboard now,
and this requires making the schematic first)
But during school i used to drive my teachers crazy by working without a
schematic.
(we had to build circuits then ranging from simple wall installation to
more complicated logic or analog circuits).
It always worked, so they didn't manage to force me drawing a schematic.
Well, tell me what you think about the "alcohol plotting" stuff..
