Infrared Infrastructure


Portacabin with hotspots.

I recently went to EMF Camp (which is Glastonbury for geeks - lots of random electronics, talks, art, and camping). Naturally, I took along my Infrared camera and pointed it at interesting things! First up… sewage! Festivals often have big tanks to take away human effluence. But how can you, a normal human, tell how full they are? Luckily, fresh sewage is warm. Phone boxen were plenty - thanks CuTel. Because the metal of the box is cold and human fingers are warm, it's possible to see r…

Gadget Review: KAIWEETS KTI-W01 Thermal Imaging Camera


A thermal selfie.

The good folks at Kaiweets have sent me their KTI-W01 Thermal Camera to review. You can use coupon code TEB15 for an exclusive 15% discount. Let's get this unboxed and working!

Here's the full photo taken with the camera. It shows the interior of an office with some computer equipment on a shelf. You aren't…

Review: InfiRay Thermal P2 Pro USB-C Camera for Android


Screen with lots of options.

The good folks at InfiRay have sent me their latest Infrared camera to review. It is tiny. It's smaller than a normal USB stick and barely weighs anything. Shove the USB-C protrusion into your Android phone, launch the app, and... nope - that's it! Pretty much instantly plug and play. There's also a reasonably long USB-C extension cable, so you can poke the camera in small places without needing to get your phone up close to something hot. But, if you do want to get close, the magnetic…

Reverse Engineering the .IRG infrared thermal imaging format - help needed


My smiling post. My nose is very cold.

I always find it depressing when I reach the limits of my abilities. I have a new Thermal Imaging camera. It automatically saves photos in two formats. The first is a standard JPEG with false colours and metadata superimposed. The second is a .irg file which can only be opened by the Windows-only software which comes with the camera. Judging from what that software shows, the .irg contains a raw thermal image and separate metadata. That makes it more useful for analysis. What I know…

Gadget Review: Topdon TC004 Infrared Camera


Liz is rendered in warm colours. The freezer is dark. The temperature range goes from mid 30C to -17C.

A few years ago, I tried out that Seek Thermal Compact Infrared Camera which is a USB addon for phones. It was a good gadget, but had a number of compromises to get it into such a small form-factor. I've just been sent the TopDon TC004 handheld thermal camera to review. It's a chunky beast of a device. About the same size as a large barcode scanner - and pretty weighty. It promises superb thermal imaging, video recording, and a host of useful features. But how does it do? And, more…

Experiments with Far Infrared Heating


LED display with lit up buttons.

What with the situation in the world, I've been trying to reduce our domestic gas consumption. Looking through our smart meter readings, our biggest usage is heating (in winter) followed by hot water (showers and baths) then cooking. We have a Tado smart thermostat which turns the heating off when we're out - but I wondered if there was something more efficient we could do. Burning gas to heat water to pump around a home is… daft. It's noisy, expensive, requires a yearly service, and is d…
