Revisions for Thermal Flashlight

11 CURRENT	warren	February 18, 2020 22:54 \| over 4 years ago A "Thermal Flashlight" is a DIY device which lets you do a kind of "light painting" -- thermal photography. It produces a colored "heat map" overlaid directly onto a photo of a room. This is the simplest, cheapest, and to date, most effective way we have developed of measuring heat leaks or cool leaks indoors and outdoors. Simply put, the "flashlight" puts out redder light if it's pointed at something hot (default 75 deg F or more) and bluer light if it's pointed at something cold (default 60 deg F or less).

Try to stay out of the way of the beam, and don't point it directly at the camera or it will create a "starburst" and may mess up your image.

4	warren	September 25, 2017 15:56 \| almost 7 years ago A "Thermal Flashlight" is a DIY device which lets you do a kind of "light painting" -- thermal photography. It produces a colored "heat map" overlaid directly onto a photo of a room. This is the simplest, cheapest, and to date, most effective way we have developed of measuring heat leaks or cool leaks indoors and outdoors.
