Giant QWERTY Keyboard

An educational tool for preschool and kindergarten age children to learn the alphabet, learn to read and write while playing with a computer. Video (last slide) shows giant QWERTY keyboard in action.

While corporate electronic designers were making computers smaller, I made this keyboard bigger for children to learn.

Skill required to build:

1) Basic wood working skills and basic shop tools

2) Some soldering

3) A lot of cutting with Exacto knife, sharp blades and scissors

4) Volt meter handy to check continuity and shorts

Art board, foam core, fish aquarium filter material, 1 inch brass strips, screws, washers and nuts, surplus phone wire to connect giant keys to PC keyboard, contact cement, paint, wood, wood screws. Old computer and software.
