IR Blue – Cheap Open Source Thermal Imaging
For those that missed it RHWorkshop started a Kickstarter project back in December 2012; to build an Open Source, Cheap and Affordable Thermal Imaging Camera, for use with Apple IOS or Android devices. Thermal Imaging Cameras typically cost approximately $1,500USD, this device costs $160USD (just over 10% of the value, compared to a professional piece of kit).
Today, I finally received my DM kit 🙂 I spent approximately 30 minutes assembling the through-hole device (Hint: You can purchase a pre-made fully assembled device for $195USD, if your soldering skills aren’t up to scratch. I really like my electronics projects, and have built other projects such as Adafruit’s Ice-Tube Clock). Annoyingly, I was 1x 1µF capacitor short :(. Luckily, I had a spare low voltage 105 ceramic capacitor in my kit, and it was easily replaced 😎

The main topic photo above is the first object I snapped with the newly assembled camera; A thermal image of the Raspberry Pi. You can see the Processor glowing red at approximately 33°C. The alignment is a little off at the moment, I just could not wait to test this little device out; Now I’m busy getting familiar with the application controls, and settings and correcting the alignment problem from my eager first photo.
The IR-Blue lets you see the temperature of things around you. It uses a 64 zone non-contact InfraRed sensor array to read the temperature of what you are viewing. The IR-Blue connects using Bluetooth to your iPhone or Android device to show the temperature readings as colors on the screen.
The IR-Blue supports Bluetooth 2 and Bluetooth 4 BLE. It works with the iPhone 4S, 5, the New iPad’s and the 5th gen iPod Touch. It also works with Android 2.3 and newer devices with at least 480 x 800 resolution displays.

Now to start taking thermal image captures of other devices around the home/office 🙂
Thank you Andy Rawson for this affordable device.
Where to buy one?
My Motor… taken on an iPhone5, IR Blue (Moments later it started raining, I’ll wait until its another dry day and take some better comparison pics with Android & Mardarso)
Pi… taken on iPhone 5, IR Blue (Better aligned this time)
Pi… taken on an Android HTC 1X+ , Mardarso (Top = Default Mode, Bottom = 8Hz Hack)
My hand… taken on an Android HTC 1X+ , Mardarso (Top = Default Mode, Bottom = 8Hz Hack)
You cannot see a lot of difference with the Pi pics, but you can see a difference on my hand; one pic you can clearly see it outlining my fingers, as opposed to the other where my hand is one big heat blob.
