It's not maker-made, and I don't propose a remake - Fluke's Ti25 Thermal Imager is just too future-cool not to mention. The device combines infrared and visible-light images - now you can simply glance/scan back into a room to see if you left the iron/oven/soldering-iron on. Needles to say it's pricey - suppose I'll wait for the ocular implant version - Fluke Ti25 Thermal Imager
