Homebrew PCBs

It's interesting that Zoran published his plans this
time of year. The use of paraffin as a resist has a
long history in decorating Easter Eggs. Google Ukraine
Easter Eggs for some incredible desings.

Paraffin is also used on fabrics for 'Batik' designs.

I was surprised to see no dots visible in the enlarged
traces, and some of the right angles were very sharp,
may be too sharp.

I would also like to know how long it takes to plot a
board. The fine diameter of the needle neededto ge the
resoltuion shouwed, would indicate many many passes to
make a wide line. Yet the lines seem to be completely
filled.

Overall its an interesting application, but very
similar to using a "sharpie" marker to draw out the
pattern.

TANSTAAFL!
