Halloween Forum member Havok1919 built this Halloween gravestone he calls the Technological Tombstone of Terror. The tombstone itself is constructed from pink insulation foam, adorned with prop bones and pre-cut wood scrollwork. It was then was finished with acrylic paint applied using a paintbrush and an airbrush. For the flaming pentagram, he mounted an old LCD monitor inside the tombstone, which plays a video loop of flames. To achieve the laser effect behind the skull, he used a small mirror on a DC motor and pointed a green laser diode into it. A small fog machine and a few LEDs finish off the nice lighting effect. Luckily for us, he has documented his build in great detail. Nice work! [via Adafruit]
