I took my daughter to the library yesterday1 and they were having a huge book sale.  I’m such a sucker for a used book sale.  Some of my most cherished books were previously cherished books.  :)  While rummaging through the books I found one that was a children’s board book with a list price of $20 that had about a dozen pages with colored musical sheets – and a simple electronic piano at the bottom, circa 1998.

What surprised me about the electronic piano is the number of keys it has.  Most children’s toys that incorporate an electronic piano have about 13 or so keys.  This one has 23.  You could actually play some music with this thing.  The speaker area was SO big that I knew it had to be a conventional magnet + copper coil speaker rather than a cheap piezoelectric speaker – the kind you find in annoying greeting cards.  When I held it to my ear and hit some keys, I could just barely make out a tone over the low din of other book lovers milling around.  At $0.50, I SNATCHED it up.

Here’s my plan.  Rip the entire plastic piano off the board book, replace the batteries, rip out the old speaker, replace with a cheap piezoelectric speaker from an annoying gift card, and turn it into a very tiny piano.  It’s not going to change the world or anything, but it is a fun little project.

I’ve already stripped it off the board book, replaced the batteries, and tried out a piezoelectric speaker – only to find out my piezoelectric speaker was broken.  :/  I’ll have to find a new one.  The piano is surprisingly loud – but my daughter got a kick out of it.
