I have a 100 year old house that can be drafty and hard to heat in the winter. I have been wanting a thermal imaging camera to help find leaks ever since we bought this house. So I finally just made my own.The temperature readings are overlaid onto the phone's camera display. The display is adjustable for different temperature ranges and can show the numeric reading for every zone or just 1.
No, it is not as nice as the $2000 - $10,000 cameras but it is good enough for most things you need a thermal imaging camera for and it is also rather fun to play with too.
I would like to make and sell these so others like me can save money and energy. I should be able to manufacture and sell them for around $150. The software for iPhones is ready, the Android software will be available soon. This is also going to be an Open Source Hardware project so if you want to make your own that is fine too.
UPDATE: The Kickstarter is now live!
PureEngineerLLC made it!
