The swell paper does not lend itself to fine lines. The hot pen would and
does in deed work, althoug I've never tried with alcohol. The soldering
pencio is hot, but the swell paper actually absorbs light energy, and I
think it morphs badly under the intense direct heat. I haven't used it
lately, but it was at that time about a dollar a sheet.
Actually, a netlist is not too far removed from the verbal schematics we
blind folks use an write. The verbal schematic is simply a description of
what connects to what, done in a logical, sensible preesentation. It has
several advantages over conventional symbolic schematics. However, most
engineers are not good communicatorsz, and fewer still are creative. So,
most ask: "Well, where do I start? There are so many nodes here!"
The verbal schematic technique can abe applied to simple circuits, or to
complex logic and analogue circuits including those fierce PLLD designs.
