I would love to see your community's feedback on a new EMF detector I developed for iPhone that's on Kickstarter right now.
Mr.Ghost is a gadget that plugs into your mic port and allows your iPhone to sense electromagnetic fields around your house. It’s not quite a Tricorder, but we’re working on it.
It uses the gyros in the phone so you can swing it back and forth and find the sources of the EM radiation. This is particularly useful if you’re curious how much EMF your household appliances put off, or if you’re feeling more adventurous and investigating a haunting. Mr.Ghost gives you the option to record the fields and listen to them, as well as a more Lord of the Rings option where the detector glows brighter the more powerful the EM field is.
It just launched on Kickstarter today and backer rewards starting at $20 include the device. The first 200 will ship before Christmas, so people can track Santa down, assuming he produces a lot of electromagnetic radiation. Kickstarter link: http://www.kickst
