Gadget Review: KAIWEETS KTI-W01 Thermal Imaging Camera
https://shkspr.mobi/blog/2024/04/gadget-review-kaiweets-kti-w01-thermal-imaging-camera/

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!

Demo

Photos

The photos are stored as JPGs which can be read by any normal graphics program. They also contain the thermal metadata which you can extract with specialist tools.

Here's the full photo taken with the camera. It shows the interior of an office with some computer equipment on a shelf.

Infrared photo.

You aren't going to get high-resolution photos out of this - 256x192 is what the thermal sensor provides. That's overlayed on a graphic.

It includes different filters so you can see just the thermals, the real image, or a mix of the two.

A thermal selfie.

Because the optical camera is quite some distance from the thermal camera, it doesn't cope well with close ups - as you can see. Luckily, this can be adjusted in the UI by pressing the up and down keys.

Videos

As well as static shots, it will take video - 240x320 resolution and 25fps - well, ish. It looks a bit jerkier than that to me. But it is good enough to see what's going on.

In this video, I've recorded a bath filling up. Towards the end, I've changed the settings so it shows more of the real-colour video with the heat overlayed.

https://shkspr.mobi/blog/wp-content/uploads/2024/04/bathtub.mp4

Filesize is about 1.5MB per minute - I've recompressed it for upload. I couldn't see any specific thermal metadata in the video.

Linux

Amusingly, it shows up as 1f3a:1000 Allwinner Technology Prestigio PER3464B ebook reader (Mass storage mode). Nevertheless, the 30GB volume was mountable and had an IMGS/ directory full of JPGs.

There is a Windows app, which I was able to run in PlayOnLinux. It offers a few features, such as being able to change the colour scheme of the photo, and pick out specific temperature points.

What's Great

The integrated lens-cap is is a thoughtful touch. As is the hand-strap and included padded case.

The trigger action feels great and is instantly responsive. There are a bunch of menu options if you like to fiddle with things.

Oh, and it is USB-C! So it will take the same charging and data transfer cable as all your other gadgets.

Overall, a nice package.

Downsides

The button layout is a little odd. The buttons feel nice and are responsive. But I would have expected the "Enter" button to be in the centre of the directional buttons.

It is a little slow booting up - but then, this isn't designed for quick action shots.

After taking a photo or a video, it asks if you want to save it every time. That's a little annoying. There's 30GB of storage and photos are only about 300KB - so it should be good for about 100,000 photos.

The videos are recorded without sound. A cheap microphone would make it easy to narrate what's going on in a shot.

Weirdly, the bundled app doesn't work on videos.

There's no expandable storage - the 30GB is plenty, but sometimes it is easier to shove an SD card into a computer.

Finally, there's no mounting point. Other cameras I've tried have a connector so they can be attached to a tripod. This is strictly hand-held only.

Verdict

This costs £200 - £250 depending on whether the algorithm likes you. Astonishingly, that's cheap for a thermal camera of this quality!

If you're into DIY, or you want to check the thermal efficiency of your home, or you just want to see how hot things are - this is a useful bit of kit. It's sturdy and well built. Dragging images and videos off it is a breeze - even if you don't use the official app.

The interface isn't the greatest thing in the world. But all you need to do is point and click. It's the sort of thing that's unexpectedly handy around the house with all sorts of tasks - from checking if the radiators are balanced, to seeing if a hidden plug is spewing heat.

£200ish isn't cheap cheap. But it is cheap enough that most geeks should have something like this. Also worth buying for community groups who want to check for heat leaks in their properties.

If you are happy with the slight user-interface oddities, and don't need a tripod mount, this is an excellent gadget.

Now introducing: !

1.7 kW worth of raw USB-C PD power.

24x USB-C ports.
4x 100W, 20x 65W.
(4x USB A, but we don't talk about those :P)

I never did a post of the project that @techbeard and I did last-minute before , so here you go.
Build log in the thread below.

Back view. The back consists of another milled PCB that holds the Powercon True1 power input socket, the XT60 24V power output plug and a large OLED screen.
View of the OLED screen in action at the Geekend Aalen '23. It mainly shows (a rough approximation) of the overall power draw and some internal stats.
The being utilized pretty heavily at the Unterland village at CCCamp23

I ordered a handful of either module and tested them thoroughly.
Both support all relevant #usbPD profiles including PPS and a bunch of other fast charge protocols.
Thermally they behave pretty good aswell. Both #thermal pictures were taken after about 15min of 24V input and 60/95W load in open air.
The hottest component of the 100W module is the 5A SMD fuse with over 100°C :D
But our planned thermal solution should improve things a lot ^^

#PDBrick #usbC

Thermal picture of the 65W module. The hottest part is actual IC with about 80°C
Picture of the 100W module connected to a PD analyzer. This time the different PD profiles are displayed. 5V, 9V, 12V, 15V with 3A and 20V with 5A. Also PPS from 3.3-21V @ 3A.
Thermal picture of the 100W module. The hottest spot is right where the fuse sits on the underside of the PCB with 98°C. Other components are under 80°C.

Alberta’s decision to “pause” energy development has disappointed Indigenous communities and businesses.

A regulator review will prohibit approvals of new wind, solar, thermal and hydroelectric applications until Feb. 29, 2024, and is expected to impact 118 projects, six undertaken by Chiniki First Nation, Paul Band, Ermineskin Cree Nation, Piikani Nation and Sawridge First Nation.

“The storage is also deceptively simple. Instead of using fluids such as molten salt with temperatures of 600°C or more, RayGen has borrowed from conventional district heating and geothermal technologies, and uses hot and cold ponds, low temperatures (90°C) and Organic Rankin Cycle engines, which have been around for years.”

Just realized you fan use the thermal satellite sensors to determine where is likely to be the hottest part of the park, based on thermal signature from other days.

How to improve #thermal #design over the typical #Dell and #HP #OEM #computers cases, in a few seconds: flip the case 90° and put it on blocks to leverage natural #convection.

Why "intake underneath, exhaust at the top" never became the standard among mainstream #hardware #manufacturers, after all these years, eludes me. #lifehacking

Some #thermal camera product codes to search for. #DIY #Repair

  • TR160i (160x120), TR256i (256x192) - 25hz USB Dongle style thermal cameras.
  • TR120E (120x80), TR160E, TR256E - 25Hz standalone thermal-only cameras.
  • TR256B - 25Hz standalone thermal-fusion camera.

Gadget Review: Seek Thermal Compact Infrared Camera

Winter is coming! And, as such, I want to check which parts of my house are leaking heat. So, the natural solution is to buy an Infrared Camera and point it at things!
