Hello all,
My son has recently asked me to sort out his "Leappad" electronic
reading aid. Its a bit of kit which looks like a large green and blue
hard back book. You open it and place a printed paper book inside it.
As you open the pages it allows you to place a stylus on the printed
book and it will read words, sentences or phrases out of the book.

Anyway to the point. The stylus started erratic operation and I found
that by holding the stylus in a particular place the stylus worked OK.
So I deduced a fractured wire. The stylus can be removed and unplugged
from the main unit. I had to force open the stylus to replace the thin
coaxial cable connecting it to the main unit. All that was at the end
of the stylus was a 3-4mm length of the coax with a small brass
"nipple" on the end. Nothing fancy at all.

Needless to say it does not recognise what part of the page you are on
or even that you have placed the stylus on the paper. Under the book
is a large plastic membrane with like an XY matrix on it.

Anyone got any ideas how it works. I suspect the matrix is scanned
quickly and wherever the stylus rests tells the unit where the stylus
is. One idea......

I've searced the net and found nothing, and it seems a shame to bin it
as he gets loads of fun from it. Over to you.....
