In case anyone is thinking of buying a thermal imaging camera to find out why their latest project is smoking, Flir's new E4 can be easily hacked to the same spec as the $6000 E8 model

Is it just a text file hack ? It seems thats what your post implied.... I'd love to up one on my drones here in northern California. We are approaching the season where Cal fire begs farmers and ranchers to burn everything .

Almost - edit a text file, run a CRC utility on it and upload the edited file via USB. No changes to any existing file on the unit.
There are now some additional hacks being tested that enable features that aren't even available on the top model, like manual temperature range setting!
Better get in quick as they've been flying off the shelves - there is very little stock around now- Tequipment sold out 12 units in a day after it appeared on Hackaday.

I was keeping an eye on the EEVBlog thread too, but its blown up a bit much to take it all in. But did you get 60Hz working yet? Keep up the good work, sometimes when I'm winding down in bed on the internets, I dont feel like listening to all the yelling and shouting in my teardown videos. ;)

No - I suspect the framerate is baked into the FPGA, however there is a 60fps datastream available from the sensor - will investigate this at some point but I suspect it may need quite a lot of processing to be useable, and signal-noise may be limited by the small lens.

Very cool. I may have to invest in one!
Some questions:
1. How easy is the actual hack? Does someone need to be a computer science engineer to perform the hack?
2. Does the hack provide all the functionality of the $4995 e8 model?
3. How many people have verifed the hack? Any reports of FLIR modifying newer revisions to disable this hack?
EDIT: Well . Just bought one. Hope this hack is for real!!

1. How easy is the actual hack? Does someone need to be a computer science engineer to perform the hack? [/quote] You need to be able to edit a text file and run command-line utility. If you can't figure it out, ask a schoolkid to help you! Read the hack instructions liked to at the start of the eevblog thread.

Yes. There is some speculation that the higher end model may have a sensor selected for fewer dead pixels, but DPs are very effectively masked so not an issue even if his is the case - I only found out mine had a hundred or so by turning the masking off There is an additional hack which enables features that aren't even present on the top-end model, including manual temperature range selection, more pallettes and measurement modes Oh, and I think the E8 includes a spare battery and external charger. Whoop-de-doo

At least a dozen definite, probably several times that. If there were issues there is no question we'd have heard about it by now. Nobody has had any issues. The latest firmware version tested is 1.19.8 I think. Many dealers have sold out and are expecting new stock this week, and a few EEVbloggers have units coming from this stock so if there are any 'fixes' we'll know soon enough.
Tequipment sold all the 12 E4s they had in stock in the 24hrs following the Hackaday post

This explains everything, the yields of those 320x240 imagers is quite low (I was working for a company which made similar devices, and for higher resolution sensors the yields were on the order of a percent, that is one out of every ~100 sensors meet the dead pixel specs), so it would make sense that they would take a device which they would otherwise have to throw away and put them in artificially 'crippled' cameras programmed to interpolate away the dead pixels.
It is a nice trick to be able to un-interpolate them though!
