Sometimes you need fill sound for a suspenseful scene or creepy noises to create a fake out scare. If you have music equipment, you might be able to chain a few effects together and come up with something usable. Or if you’re feeling in the mood for a DIY project, why not build yourself a Tesla Spirit Radio.

The video is a little cheesy, but the sounds out of the Tesla spirit radio are very useful. Record 5 min of spirit radio in a thunderstorm and you could have a background track as cool and classic as Forbidden Planet. You can find the list of parts and the instructions for building the Spirit radio on the instructables page.
