Seek Thermal has released the Seek XR, an extended range version of its thermal camera accessory designed to be used with Apple iOS and Google Android smartphones or tablets. The new extra range model is created with outdoor enthusiasts in mind, allowing people to literally see heat, making it possible to spot people and animals in total darkness. For hunters, the Seek XR can be used in daylight, the dark, or in obscured visibility conditions. It’s useful for scouting, blood trailing, hunting game, and much more. The new Seek XR has a manual focus lens for viewing objects at close range, or at distances of up to 2,000 feet or around 610 meters.


Specification wise the next Seek Thermal XR is identical to the standard version of the thermal imaging accessory, the only difference being the lens used on the two models. The long range XR version comes with a manually adjustable focusing lens and a reduced field of view of 20 degrees as opposed to the fixed focus lens and the 36 degree FOV of the standard Seek Thermal version. According to the manufacturer the XR model is ideal for Hunters, Boaters, Campers, Electrical Engineers and anyone looking for increased home security can detect intruders from nearly up to about 2 thousand feet away. As with the original Seek Thermal accessory the new XR model is available in a version designed for iOS as well as for Android with a price of $299 USD as opposed the $50 USD cheaper standard model that is available for $249 USD.

The Kalt Sensor is a small accessory for your smartphone or tablet that is able to turn it into a precise non-contact infrared thermometer. The device plugs into the headphones jack of your iOS or Andorid device and after you install a dedicated application you are able to measure the temperature of various objects around you. The Kalt Sensor essentially reads the infrared energy that the object emits and translates that in user readable temperature of your choice in either Fahrenheit, Celsius or Kelvin. So by adding this sensor to your mobile device it will become much like those portable gun-like infrared thermometers sold at hardware stores. The project was successfully crowdfunded on Kickstarter raising $11100 USD with 217 backers, but if you missed to back it up then you can pre-order your sensor from the official website. The product is available in two main versions – with normal and with extra range sold for $43 and $48 USD respectively as well as in 4 different case colors and with an optional extension cable.

Kalt Sensor Specifications:
– High accuracy of 0.5°C over wide temperature range
– -70 to +380°C for object temperature
– Field of view 90 degrees (2:1 ) for normal model
– Field of view 35 degrees (6:1) for extra range model
– Displays the temperature in large , easy to read numbers
– Emissivity: 0.1 to 1 selectable from the app
– Response time less than 400 msec

What is important to note when choosing between the normal and extra rage model is the distance and size of the objects you are going to be measuring most of the time. The normal range model is for measuring larger objects from close distance due to the low ratio it has, so for example form 2 centimeters distance you will be measuring the temperature of a surface of 1 centimeter. The extra range version will allow you to measure the same 1 centimeter surface from 6 centimeters distance, or about 0.33 centimeter surface area from 2 centimeters. So make sure you have this in mind when deciding between the normal and extra range version.

Nowadays the PCs are designed in a way that their cooling solutions take out all of the hot air from inside to the back of the computer case. All of the heat generated by the processor and the video card is usually moved from the insides of the PC case by fans located at the back side of the case and then above or below them is the power supply that also brings out some of the hot air, though often it is mostly giving out heat that is generated by the PSU itself. There are of course some computer cases that have places for a lot of cooling fans and the user has the ability to change the way the cooling works by changing which fans take cold air from outside and which bring hot air to the outside. In the specific case we have here the computer case has two exhaust fans on the back and on top of them is located the power supply. As you can see on the thermal image some of the components inside the PSU are apparently getting quite hot when the computer is under heavy load.
