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.
Step 1: Built wood frame to hold attach the material and begin assembly
Keyboard is older model where each key has two solder points on back of circuit board to attach/solder wire to cause short and trigger event (letter).
Sand paper letters based on Montessori method of rough/smooth, tactile senses to trace and learn alphabet
Step 2: Design and assembly begins
Design and assembly time took 200 hours. Conservative estimate.
Step 3: Exploded view of each letter assembly
Step 4: Picture collage, painted and unpainted versions
Painted version used for trade show booth.
