My good friend graduated last semester, and gave me the light table her husband built for her while at AAU. A great piece of equipment expertly constructed. No surprise, as her husband is an engineer.
He built it using two pieces of pre-cut plastic, and three pieces of particle board that he sawed himself.
Inside he attached a fluorescent bulb that is easily replaced.
And used household screws and little soft discs to keep the table from scratching surfaces.
Beautiful. Simply beautiful. And free!
