Homebrew Wooden Cellphone

Homebrew Wooden Cellphone - RF CafeMIT PhD candidate David Mellis has recently achieved fame for his custom designed and built cellphone. $150 worth of cobbled-together parts got him a GSM phone with an 1.8″ color , 160×128 pixel, TFT screen. He used a clever way of forming the pressable buttons in the plywood cover. Digi-Key must be happy with the unintended product placement opportunity in this picture of David and his companion trying out his wooden phone.
