I had so much to do today. Then I found this channel. Like most of us, I can hardly resist disassembling everything and anything I can get my hands on....but this...is on another level!
Excellent video Mike. We use a thermal imaging camera for finding rogue thermal issues on equipment during shows, and I wondered why it kept making that clicking noise and shuttering the image. Expensive toys, but quite frankly, they're well worth the money in terms of usefulness.
This is the single most informative video I have watched for a long time. I am learning quite a lot from your episodes, like debugging and fixing real live devices and how to properly use an oscilloscope and "your wits".
I was totally fascinated by this entire video, loved watching the diagnosis and repairs, especially the twisting of the board. I also thought your modifications were thoughtful and well done, including making the battery an interference fit for the ac plug. My girlfriend watched quite a bit of this vid as well. Her comment... "Yeah, that was a great video." Now, that's someone using their noggin" Bloody Brilliant
Love the teardown & repair rolled up in one. Having moved away from electronics professionally this particular video reminds me what I loved about repairing boards/systems that came back from bouncing around oil rigs worldwide. Nice one!
Great work on locating the intermittent ! I always have the scope out hooked to an amp and speaker so I can hear it. Find any point that makes or changes noise with the intermittent and you can then poke away while not trying to look at a scope or meter . I find the ears so much better in this situation. I laughed out loud when the shorted trace lit up in the camera display ! It's like not paying taxes ! Thanks again for sharing your wealth of knowledge with us lower life forms.
I cheered when you first got it to work, LOL. Keep up the good work with the videos Mike, love the work. We used to use those cameras in the electrical industry for locating hot joints in high current switch boards.
I have read about using photographic film as a filter for webcams (presumably mainly passing near IR), but it might still be interesting to see how some different types of film (polyester, PET, cellulose acetate or nitrocellulose) behave when viewed in FLIR, (floppy disks are also apparently polyester and work as webcam filters), thanks for all the great videos, you dave(eevblog) and tesla500 are the definite stand outs for teardown and electronics videos.
What a bargain, well worth the risk! Great video, so satisfying to get something back up and running. I'd like one to find heat loss / damp in buildings.
A real joy to watch these vidoes Mike! Having a job that contains similar work I can absolutely relate to your mindset! That said I am not even nearly as experienced as you, so watching has quite an educational value! Thanks for putting work into this and uploading them to youtube! =)
Wow nice job repairing and loved the in depth repair vid. Now I want to get one of these that was very neat what you did showing what things the thermal cam can see through and what it cannot see though. And I am very new to electronic repairs but I have been doing more and more some failed but the most part my repairs have worked.
Nice! My dad is a firefighter, so I have gotten to play around with an infra-red cam a few years ago. Very interesting devices, I love how you can can actually draw with heat :D
Holy crap, nice! :D Also, keep up the awesome vids. I especially enjoy the teardowns/repairs of already-broken gear that was acquired free or nearly free. :)
Back when I did electronics repair at a small shop we used to slap around TV's and used plastic paint brushes to find faults. When we had the general area narrowed own it was magnifier time, could almost always see the cracked solder and if not we'd just reflow anything heavy in the area.
I just want to let you know that during my training with the US army we use ENVG's which have an integrated thermal vision + night vision and is the size of the palm of my hand. Very handy in detecting enemies in thick bushes and mist! Creates a red thermal outline overlaid on top of the night vision. Tech has advanced real far here.. Only if we could get you one for a teardown!
I just love the idea of buying random stuff on ebay and trying to get it to work. (or if it can't be fixed, repurpose interesting parts or the case for something else)
Great video! At around 35:35 you talk about a 32kHz watch crystal. It might be used not for a real time clock, but as the reference for an internal PLL of the processor - a lot processors use this approach.
Interesting video, Thanks. I think that the sensor is likely cooled thermo-electrically to improve its sensitivity. The sensor would be in vacuum and thermally isolated from the case and electronics as you speculated. While this is not required for low performance sensors, it is likely needed to achieve the sensitivity and performance of the images shown. You are seeing residual heat differences of a few degrees or less in the images. Military FLIRs run at liquid nitrogen temperatures.
One of the most interesting teardowns yet! I'd love something like that to pull the guts out of (or even better, get it working!). I should keep an eye on more "junk" auctions.
KingofKatenfutter I have a Kenwood from 1998 with a colour LCD display and incandescent backlight! Probably because LEDs were expensive at the time and since it wasn't battery powered, who cared if it consumed 100mA more?
Can be quite twitchy when first turned on but after settling down, only every few mins - my guess is it does it when it sees a certain amount of temp change on the lens body, with a timeout of a few mins when stable.
How you traced that fault is fuckin' magic to a muggle like me. Makes me really want to get into electronics more, but haven't an idea of where to start...
Thermal imaging cams have TEC/Peltier cooler that needs to be conected to a very big cooler! It is needed so the CCD is kept at a very low temperature.
8:10 seen these years ago in the then popular "pocket" TV's :) Thanks for the long video, not least because there was nothing on TV tonight ;) The only complaint I have with videos like yours and EEVBlog etc is the price of similar items on Ebay are going to skyrocket :p
They're fairly standard 2mm socket probes - more useful on PCBs than standard probes - sharp tip helps penetrate resist & gunk. Just don't use them on 3-phase distribution panels!
I have tried a few experiments and it seems that such modified cameras would start to show light from thermal emission somewhere at about 350 to 400 celsius range. However, the emission is very limited at such low temperatures and is easily swamped out by reflection of ambient NIR, so near darkness or working under lamps that does not emit much NIR is necessary for experiments. but you can take some interesting images of things by reflected light, too, things look somewhat different in NIR.
You can find similar cold cathode backlight things in "vintage" Canon digital cameras, and also in some camcorders viewfinders, I have a few of them. Wonderfull teardown, thanks for sharing, you push the level a little higher each time, what will be the next one ? :)
Ooh that's very true. I imagine something like this could be a useful tool in determining faults in boards where components heat up in that manner. I actually bought a laser thermometer for that very reason, and it's been invaluable :) It's such a shame these thermal imaging cameras are so out of my price range :(
The copper pinch-off tube looks exactly like those used to seal ion pumps for shipment (I work for a company that used to distribute high vacuum products), so I'm inclined to agree with @Doug Fuller; the imaging sensor is likely to be under vacuum.
mikeselectricstuff makes it look faster than it really took... You mean the time it took plus the time you've invested learning what you are doing? Like twenty years or more? Yeah, that explains the value of your work. Bravo and I love you! Thanks for being so damned competent!

Your troubleshooting process is mesmerizing to watch. Thanks for documenting the whole thing!

What an absolute belter of a video Mike. Skills to die for.
Many thanks.
£222 and an hour's work, that's got to be one of the best thermal imaging camera deals ever!
This is probably one of the most interesting video's I've seen so far. You tested all kinds of things with that camera I would do when I had one.
Love the teardown & repair rolled up in one. Having moved away from electronics professionally this particular video reminds me what I loved about repairing boards/systems that came back from bouncing around oil rigs worldwide. Nice one!
Best video I've seen on your channel so far! Great repair and presentation of effects at the end.

Just long enough! Had me enthralled the entire time. Thanks Mike.

NICE a 54min long vid. I'd run out of your tear downs, I've watch them all. Waiting for more :)

excellent fix up and teardown.i learnt loads .
What a bargain, well worth the risk! Great video, so satisfying to get something back up and running. I'd like one to find heat loss / damp in buildings.
Nice teardown and congrats with the repair.
Absolutely excellent video. I really enjoyed that one!
Another great video, Mike. Bravo!
GREAT electronic teardown Mike !!!!!
good job Mike, love the fix up
Thanks for sharing this Mike. Its the most interestingBest electronics video I've seen in ages.
Excellent work and great ending Mike!

Wow. Awesome repair & mods!
Great!. The camera resolution is feels awesome.
Great video, love seeing unusual equipment!

Super interesting video, Mike. As per usual, I love the ending.
Nice to find a Brit with some quality content :D
Thanks for the heads up. Imagine how embarrassed I'd have been in my transparent hiding place.
this channel is totally amazeballs.
Nice! My dad is a firefighter, so I have gotten to play around with an infra-red cam a few years ago. Very interesting devices, I love how you can can actually draw with heat :D
great work and wonderful video. Thank you.
In other news... we have the same watch! 5 years and going strong
watched the hole thing. great! really enjoyed it
Wonderful and educational video
This was brilliant, thank-you
Holy crap, nice! :D Also, keep up the awesome vids. I especially enjoy the teardowns/repairs of already-broken gear that was acquired free or nearly free. :)
Fantastic video, thanks for sharing!!!
Very interesting and fascinating. Please for the love of all that is sweet and pure, never stop making videos. :)
Nice mods & a great repair! Cheers for the upload
Very carefully.... just pre-bent wires to sit in the right place and hand-held before gluing
Great video. I like these long ones. 47:50 "I just noticed the clicky thing wasn't clicking"
Can't wait to watch, still at work now!
Man I wish I could get cool finds like this on ebay, you are lucky.
Forward Looking Infrared cameras are awesome!
I really enjoyed this video 😀🖐
Great video!
wonderful video!!!
(7:17) - "...obviously, salt has, er, some slight life-time issues when it gets wet..."
Just another reason I so *_love_* this channel.

epic video! I would love to see some night shots, fire, etc
Thanks for the informative video!
Another super interesting video - thumbs up

You took quite a gamble there Mike . you ended up with a nice Win though .

This unit visibly auto-ranges very fast over a wide range depending on scene content.
Loved that last part xD
dude youre a beast! awesome. wish you could have shown the actual replacement of the inductor.
very nice video! thanks!
Great vid. I sell thermal (and visible) cameras and was doing many of the same demonstrations in a training class today.

amazing teardown. I wouldn't mind seeing some photonicinduction style pops and bangs recorded with that :)
One of the most interesting teardowns yet! I'd love something like that to pull the guts out of (or even better, get it working!). I should keep an eye on more "junk" auctions.
very nice video
Great job !
In old car radios from the 90s you can easily find INCANDESCENT (!!) backlight.
+MrOpenGL more like 60s-70s

Probably because LEDs were expensive at the time and since it wasn't battery powered, who cared if it consumed 100mA more?
Yes this was just the begin of the time of commercially available efficient blue/white LEDs and they were for sure not cheap.
Quite a gamble! But it payed off in the end :D
How have I missed you channel all this time ?.....Hi.
Can be quite twitchy when first turned on but after settling down, only every few mins - my guess is it does it when it sees a certain amount of temp change on the lens body, with a timeout of a few mins when stable.
No luck. Just skills!
Yes - film is good for IR-pass at the sort of wavelengths around 800-900nm that CMOS and CCD cameras can see, but LWIR is somewhat different.
CO2 laser in air is something on the list of things to try. Resolution is 320x240 - pretty high for a thermal imager.
I see a flaw in your logic...
FLIR Operator: "Dang! I lost him!"
Pilot: "He's hiding under a sheet of glass."
:P
I can give you a good tip: Use a small noozle and low temperature. And a Atten 585D ist very handy
Luck does play a part, but experience helps load the dice
I watched the entire thing, it makes me want to go on ebay and buy one and try to fix it.
Out of curiosity, roughly what would the cheapest 320x240 imager cost today?
very interesting video :)
How you traced that fault is fuckin' magic to a muggle like me. Makes me really want to get into electronics more, but haven't an idea of where to start...
Thermal imaging cams have TEC/Peltier cooler that needs to be conected to a very big cooler! It is needed so the CCD is kept at a very low temperature.
Now that was a ... cool ... video. :)

thanks for making me a bit smarter may i ask do you use one of those grounding straps around your wrist when you work with electronic goodies.
Depends on the camera. Some cameras will go up to the 10.6u that a CO2 operates at. But a lot of thermal cameras work at shorter wavelengths.
You can find similar cold cathode backlight things in "vintage" Canon digital cameras, and also in some camcorders viewfinders, I have a few of them. Wonderfull teardown, thanks for sharing, you push the level a little higher each time, what will be the next one ? :)

No- they are definitely phase-change heat absorbers. This is mentioned in the documentation I've subsequently been sent
The copper pinch-off tube looks exactly like those used to seal ion pumps for shipment (I work for a company that used to distribute high vacuum products), so I'm inclined to agree with @Doug Fuller; the imaging sensor is likely to be under vacuum.
older ones do but this and most modern ones are uncooled
Editing makes it look faster than it really is.....
mikeselectricstuff makes it look faster than it really took...
You mean the time it took plus the time you've invested learning what you are doing? Like twenty years or more? Yeah, that explains the value of your work.
Bravo and I love you! Thanks for being so damned competent!
you da man, mike, you da man.
..and Don't get me started on "Sodder"
