Flir One Thermal imaging camera teardown and hacks

[frenky]

I was thinking to replace original lens (for the Seek) with this one:

But I'm not sure what is original focal length of lens in F1 or Seek...

[Bill W]

That lens is a 20mm diameter 50mm focal length, so F/2.5 assuming the A/R coatings are over the whole 8-14um band and not just for the laser wavelength

A flir1 is 46° on a 160 pixel at 17um.... so lens is around 3mm focal length
Seek is 20° on a 206 pixel at 17um.... so 10mm focal length

A 50mm FL lens will therefore be a lot narrower field of view but also a bit less sensitive (x2 or so).  Forget temperature readings.
Flir1 comes out at 3° for instance.

I now have the flir 1.0.9 firmware update pkg.
Lets see what that contains 

now i just need to find a way to depkg the file

Is 1.0.9 an official update made by FLIR? If so, where on their website can I download it?

it's for Flir One Gen 1 for Iphone

I heard that there was some way to make the FLIR One allow charging of the phone through it, so after the FLIR One got done charging, it would charge the phone. Is there a way to do this with FLIR One for Android with just firmware hack? Or would it require a hardware mod as well?

Yes, after a FW update the F1G1 charged the Iphone after full charging his own batterry.
But the Iphone has not a USB connector.

We know. that the Android Phone work with a plugged in F1G2 as USB host.
And you can't load a USB host by following the USB specification.

But some USB host controllers in Android phones ignores the specification.
Therefore it's sometimes possible with this steps:
- use a non specification Y-USB-cable
- load the phone over USB (USB controller goes in slave mode) over the first cable
- now plug in the F1G2 in the second cable
- the USB controller goes in host mode, but the charge controller is furthermore connected to the 5V-USB power

this is completely outside the USB specification

....

another question is: has anyone stick a better lens in front of the sensor to get much better results?

I tried to change the optics . An example can be found here. In T-10 using the Lepton sensor. https://youtu.be/gUOvAg0dGxY
Or additional optics.

Hm, does not it imposes and shares 5V-USB power from phone to Flir One? I mean it can hurt the camera if its blocking 5V deliberately when connected directly.
