I was at a local store today and happened to find the Plasma disk on sale for $ 5 each. I bought a couple thinking these had to be the inside electronics of the Galaxy Quest Vox communicator. Now the big question is... Is there a source here for the shells or kits for the Vox communicator? Seemed like it would be a fun project to have a go at. If not, the plasma disk staill are quite a cool little piece. Has a voice recognition mode to light up at any sound. Seemed perfect for a project like this.
