My fiancée is very keen on arts and crafts. A light box was just what she needed to be able to trace patterns onto paper and cloth.
This light box is cheap, safe and easy to build - I put it together in two hours.
A key part of this design is maximum insulation between the internal components and the outside. This is essential with any design that involves mains electricity.
As a consequence, all solder joints are located within the box, there are no metallic parts that protrude from the inside to the outside of the box, and the electrical cord was held in place with a cord grommet to prevent the cord being cut by back and forward motion.
Step 1: Materials and equipment.
The light box was built from the following materials:
A cheap student lamp ($10 AUD).
A strong, thick-walled plastic container with a transparent flat lid that clips in place. ($12).
An electronic cord grommet. (You can buy a pack of 10 for $4).
An energy-efficient light bulb. ($4 or $5, depending on where you brought it.)
Two-part araldite glue. (A bit under $2 for one pack)
A piece of waste polypropylene (Aka. part of a cheap cutting board I bought years ago in a dollar shop.)
Extra equipment included:
A wire stripper.
A hot glue gun.
A solder gun.
A hot air gun
