The goal was to make a light box for my students to use that didn't cost me an arm and a leg. Went to the second-hand store and found a florescent light... ($4.99 with 50% off) then noticed a suitcase/briefcase ($3.99 with 50% off). I got them both and started thinking of ways to put them together.
Step 1: Painting & light
Paint the inside of the suitcase white. Better to reflect the light out. Make it brighter?
Take apart the florescent light. You only need the power supply, light, light socket part and switch.
Then I positioned the light so it was in the middle of the case; using hot glue and rivets I secured the light in place.
Note: Got new two setting hot glue gun. Two setting: Low = normal glue gun, High = burn yourself, stays runny way longer and oh ya burn yourself.
