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
255 (27%)
Yes, I'd not considered buying a TIC before, but 320x240 resolution at this price justifies it (as either tool or toy!)

Yes, I was going to buy an E5/6/8 class of unit but will now get the E4

No, but am looking out for a cheap i3 to hack

Not yet, but probably will if now that a closed-box hack becomes is possible

Ok, I managed to extract all info from putty by copy to clipboard in sections and puzzle it together. Phew!

bad news, your sensor is only 80x80
Code: [Select]
i5

Thank you so much for your help and time spent on this.

That's so odd...

I'm pretty sure they don't make a 80x80 sensor. The lowest res non-lepton sensor is a 80x64 50 micron sensor that you find in the FLIR A5.

Unless they're using the ULIS Pico80P, but that's very unlikely.

ok, you don't give up.

The next proof is your calibration file. The calibration with bad pixel mapping is taken by full resolution.

your calibration file name is ds250C_we_ap_fi_le.gan
Code: [Select]
.registry.calib.detector.deadPixMap.ds250C_we_ap_fi_le:
rw-dr--------- 0 root   root   <a> fileName        "ds250C_we_ap_fi_le.gan"
rw-dr--------- 0 root   root   <i> type                         100

you find it here
Code: [Select]
+---FlashFS
|   +---system
|   |   +---maps
|   |   |       ds250C_we_ap_fi_le.gan

you can read the gain map with exiftool

here a sample from a E40
Code: [Select]
$ exiftool ds250C_we_ap_fi_le_static.gan
File Type                       : FLIR
File Type Extension             : fff
Gain Dead Map Image Width       : 320
Gain Dead Map Image Height      : 240
Gain Dead Map Image Type        : TIFF
Gain Dead Map Image             : (Binary data 153804 bytes, use -b option to extract)

but there's another file in the maps directory called "ds250C_we.crs" mentioned, among other places, here in the allsettings-file:
Code: [Select]
.registry.calib.detector.data:
rw-dr--------- 0 root   root   <x> ds250C_we

with the exiftool output:

That kind of convice me that you are right, tomas123. But I just can't help to wonder why the resolution 120x120 is suggested here and there in filenames and the allsettings-file. Could it be that the sensor has different "modes"? ...But I'm not the one to speculate on this, all you other people here have way more knowledge about how it's normally done...

@ Maxpax:
Back then I successfully upgraded my i3 (bought about 3 years ago) with the instructions from this post. When I look at your original config file, then all the lines essential for the hack are missing. Which means that you have a later hardware revision and / or firmware version. And please note the last line of the linked post. My TIC was able to do the full 144 but it seems yours really only can do 80.

And the 120 you mentioned here are from the config file you copied from the pdf with the instructions. Because the "new" config file is successfully loaded (which means you did all the # ID and # CRC01 stuff correctly :) ) this parameter is set but sadly because of the hardware / firmware this parameter doesn't do anything. :( And even if it did, you really seem to have only a 80 sensor.

And the timestamp from January 1st 2000 is just a default time if the actual time isn't set, this doesn't mean the TIC is 15 years old. :)

I have no idea why the i-Series has three different types of sensors but it seems that you just have the wrong one. :(

Hello,
try to go to: FlashFS\system\maps\  there should be a *.gan file
ds150C_we_ap_fi_le_static.gan (from FlirC2)
ds250C_we_ap_fi_le.gan (from Flir i3... later enhanced to 120x120)
ds250C_we_ap_fi_le_static.gan (from Flir E4... later enhanced to 320x240)

I guess... this Calibration file was ever in the full resolution of the Camera.
Try to decode it with my Dev Tools file to image decoder:
http://joe-c.de/pages/posts/programm_dev_tools_133.php#bilder

from the i3 and E4 i get a 320x240 resolution, the C2 brings only 80x60... it has a Lepton core.

You wrote that exiftool can't read your

Please zip and upload your gan file. I will check it.

just for fun some exiftoool and imagemagick magics.

your ds250C_we_ap_fi_le.gan has the Flir Tag FFF_TAGID_DeadMap = 4 (see pdf)
with the config.txt file from attachment we can extract the RAW 80x80 image

Code: [Select]
>exiftool -config config.txt ds250C_we_ap_fi_le.gan
ExifTool Version Number         : 9.91
File Name                       : ds250C_we_ap_fi_le.gan
File Size                       : 13 kB
...
File Type                       : FLIR
MIME Type                       : application/unknown
Creator Software                :
Embedded Image Width            : 80
Embedded Image Height           : 80
Dead Map                        : (Binary data 12800 bytes, use -b option to extract)

>exiftool -config config.txt -b -DeadMap ds250C_we_ap_fi_le.gan > 1.hex

now convert with IM
Code: [Select]
>convert -depth 16 -endian lsb -size 80x80 gray:1.hex  t2.png
resize for better bad pixel peeping
Code: [Select]
>convert t2.png -filter point -resize 320x resize.png

Still no idea where FLIR is getting these 80x80 sensors.

Perhaps in the later versions some image processing (specifically downscaling) got moved on chip?

But that would make no sense because the E4 doesn't do that...

hmm...

My i5 is blue and gray, not black. I think it is one of the earlier versions of i5, and therefore one of the older designs. I suppose it is quite natural to change designs i the beginning of new models as a company gains in understanding from testing, customer feedback, ideas on how to achieve cheaper/simpler manufacturing and not least, providers who approach the company with deals on technology parts, such as sensors.

Anybody want to buy it?  ;D

sorry for double posting

I published in the seek thread an excel sheet to show, why the RAW values of an E4 microbolometer (response of "A/D Counts") are linear to radiance [W / m^2] (per nm wave length) and not linear to temperature [Kelvin]. The difference is not great.

Would be cool to get a firmware on the i-series that dumps full rez (320x230) to SD, since the screen can't handle more than 140x140.

We never did figure out the pinouts on those, did we?  If we did, the hazard cams from BMWs/Audis might finally be reusable, since they use the same sensor.

Hello,

I changed E30bx to E60bx and its really clear view now, thanks eevblog  :clap:
but is it possible to change settings in video mode to turn of staff on right?


If you don't understand me I attached picture below.
On first its all staff (temperatures, point etc.) on second its what I would like to have on video mode.

I would like to clear screen only on video mode - not on picture mode.

You can turn it all off in one of the settings panels - I'll have to dig out my E60 and see if I can find it.

With telnet you can use commands like

It's a sample from my Flir Exx old version without MSX

Or you can delete the logo.bmp file! (Make sure you have a backup).

Good news for those with an i50 - I have successfully upgraded the GUI to include better measurement functionality and I have also updated the IR resolution to 240x240! (up from 140x140). Funnily enough, the i60 only goes up to 180x180 I think.

Does anyone have an InfraCAM SD? I picked one up dead cheap the other day but it doesn't get past the boot screen (doesn't even show it loading up). I've tried connecting to it and pulling off the files so I can inspect them, but FTP only seems to work very briefly - any ideas?

 :scared: celebrate! not scared.

I managed to get the resolution resolved. I managed to get the menus updated. Problem. the picture in picture and thermal fusion are on the menu but I can't operate them? the other thing is Bluetooth and wifi don't seem to do anything? I don't care too much about this but the fusion or pip would be a plus. The succeeded to activate: camera record, resolution, dots, delta, isotherm, zoom.....wow it's really cool.
Thanks to mike, and everyone!

Hi, I'm new in this topic, need scope owner help with my thermal sensor (have sensor (flir photon camera) with dead electronics):



Is here exists any fella with oscilloscope (with logic analyzer may be, but i guess it's not critical) and also brave, enthusiastic and open to make few start up/initialization measurements on his sensor pins?
Looking for both owners of 'I' series and 'E' series.
