BLETCH!!!!

A handful of buffer chips (or discretes) is a lot simpler, cheaper, more
reliable, and easier to obtain than a laptop. I do object to this modern
idea of _having_ to use a computer for everything.

The other day I bought some simple electronic kits for flashing
Newtonsday [1] decorations produced by Velleman. I was impressed that not
only were there no custom chips, there were no chips at all. They were
based on 2-transistor astable multivibrators.

[1] Christmas to the rest of you, I guess.
