A set of simple electronic building blocks, easy to work with for little hands.
A sunrise alarm, controlled over the ZigBee wireless network.
An in-house paging system using ZigBee.
A quick way to attach some small lights to a Trick-or-Treater.
A 30-year old pipsqueak of a computer. My first.
A handheld version of the African board game Mancala.
My solar prayer wheel.
A custom movie-watching remote control.
The SleepLight, a night light and diurnal clock for preschoolers.
An alarm that sounds when my sump pump loses power.
