Has the hackabiliy of the E4 made you buy one :  

Yes, I was already looking at the competition at a similar price, but the hack swung it to E4
241 (26.5%)
Yes, I'd not considered buying a TIC before, but 320x240 resolution at this price justifies it (as either tool or toy!)
427 (46.9%)
Yes, I was going to buy an E5/6/8 class of unit but will now get the E4
43 (4.7%)
No, but am looking out for a cheap i3 to hack
42 (4.6%)
Not yet, but probably will if now that a closed-box hack becomes is possible

We may soon see the Lepton 160x120 available via retail outlets as well. That will certainly be interesting and a great opportunity for all manner of bespoke projects  :)

I hope so, but suspect we may have to wait a bit for it.

If I am reading that right - you can get a Lepton with shutter for $131USD.
GBP131, not US$131

BTW the 25 deg Lepton works in the Flir One - needs some butchering of plastic though. And of course MSX doesn't work. Just did it as a quick hack to test it as it was easier than taking apart my tiny cam...

@Solare,

Nothing received except your email of yesterday asking about my relationship with FLIR.
I responded to that one already.

Hi guys,

I have found Flir E4 from 2014 with the firmware 1.22.0 for sale.
Shall I expect the sensor from E8 or is still a lottery?

EDIT: Year 2014

I don't think the Ex series as we know it existed in 2004 - never-mind with 1.22.0. Are you sure it's not from 2014? And to attempt to answer your question - I don't think anyone outside of FLIR really knows what quality of sensor goes into what unit right now.

Thanks, Turbo!

People more reports please! Submit your temporal noise values!

Please also add FW version info.

There is too little statistics to make conclusions. That's why I run this survey.

In my case, Pixel Noise spatial or temporal is about 15 mK
However, spatial and temporal row and column noise is huge - at least 20 mK.

While in the early models of E4, found on this Thread (when it was possible to measure noise components on the web-service applet) these types of noise were explicitly small (4-5 mK).

I dunno what might Flir change in technology but it seems row and column noise increased by factor of 4 - 5.
Maybe they just process it faster :)

@All users of the updated E4 with MENU 2014 EX and FW 2.3.0! QUESTION!!!

I have discovered I don't have two last entries in my main menu measurements option,

see https://www.eevblog.com/forum/index.php?action=dlattach;topic=21772.0;attach=138753;image

NO Humidity and NO Air Temperature...

I am using hacks installed according the FUBAR procedure, particularly the Menu version should be 2014 EX (not the extended update to the menu)

Do you guys also missing these two lines and

If YOU DO, how do you set then the system temperature of atmosphere and the relative humidity?

IF YOU DON'T, do you have idea why I do miss them? + idea how to get them back?

Thank you!

I think the values you speak of have been moved under the color menu when you select the Condensation or Insulation alarm options since that is where the values come in to play the most.

This is controlled in design_ui.xml and toolbar_config.xml

Digging into it a little myself - the values for the menus are all there and do seem to be setup correctly comparing them to the stock 2.3.0 and prev versions as well.
I believe they were actually changed in the facet.rcc file by janekivi and that is quite a bit more involved to edit due to the need to de/re compile it for changes. :(

I don't know if janekivi wants to chime in if I am correct or not?

@BUD,

already did this. The Menu is awesome, however some the most attractive features (added measurements) are glitchy.Okay, this is "by design", but still... also, the parallax cannot be changed in saved before picture. There is knob, butt is not effective.

Anybody knows how to enable parallax editing in the Updated 2014 menu | edit mode?

@All,

anybody has good explanation, why many thermal images have 'darker corners'? Is there any connection with diffusion, lighting, illumination, scattering, reflection, absorption, refraction and other optical effects connected to glowing of thermal irradiators (planes) and their diffusional interreflectance?

I do not think you can adjust parallax in Edit mode on the camera, but you can with external software.

My E4 just arrived from a German distributor.

FW Version 2.3.0.
Hack applied, based on FUBAR instructions on a Windows 7, 32 bit system
Result: Works perfectly for high resolution and E8 menu.

The picture difference between the standard E4 and the hacked E4 is amazing!

Here is the Sensor Noise value:
.calib.nrdp.ds250C_we_ap_fi_le.measureInfo.temporalMk double 16.348786

What does that mean?
Is this a good sensor, but not as good as the one from FredB ?
I am happy with the pictures I am getting.
But I have no idea in regards to how a bad picture looks like and how a perfect picture is suppose to look like

Anyhow, the hack went smooth and I would like to say a BIG thank you to all people involved, making this happen.
No wonder, this is the most viewed thread on eevblog
THANK YOU ALL!

Congratulations!

Let's say you won a lottery!

I would be just happy to have the same sensor noise value as you have!

Absolute record was something like 12.84 or so...
The absolute looser I am with 26.56

:)

You are much closer to the first than to the second :)

I think you are happy now!

Thanks Solare,

Can you attach a picture of an IR image, so we can see the difference.
I will post a picture later and then we compare.
How about a picture of a warmed up oscilloscope for comparison?
