Yep, I think that's about right. Someone leaked a quote here smlouvy.gov.cz/smlouva/soubor/13456646/nabidka2619220014.pdf
dammit!
@@reps Paying10,000$ for 3000 hours warranty is stealing, maybe normal for Israel. Other American, Swedish and French companies sell it for less and for 12000-18000 hours warranty.
@@reps That 10K was ONLY for the K548 cryocooler, not the camera! I'm guessing 139K for the camera.
@@RightlyFreewhy does Israel pay more for cryocooler warranties?
Marco Reps has become The Signal Path for “regular” engineers. Seriously, what an engineering beauty.
Still waiting for you to read us german bedtime stories
Wow. Where the heck did you get that from?!
love how he just hearts the comment with no reply whatsoever
Government surplus auction! It was used in the 'Kernforschungszentrum Karlsruhe'
guess I spoke too soon
@@reps damnit
Seems @@reps doesn't need a dumpster room just a u-haul and insider information.
I have the HT-301 Thermal Camera. That gives me a 384x288px resolution @ 25fps. It is so compact and lightweight, that I mainly using it on my drone with a self developed driver on a raspberry pi to stream evaluated image data with openhd to my ground station.
Fun fact: It is highly possible that the HT-301 uses the same image sensor as the MIKADO (micro reconnaissance drone) of the Bundeswehr.
The price disparity between those cores and the 640x512 cores always surprises me, especially when the tau 2 cores have been out for nearly a decade. I spoke with Fairchild a while back asking them to integrate the TWV1912 but I suppose there isn't enough market for UAS...
I don't want to make an exact guess about the cost of a new cryocooler unit, but my spider-senses are telling me that it's capable of cooling down your funds to absolute zero and make you cry in the process, hence its name... :D
Thanks a ton for your videos, they are so brilliant! Super entertaining and informative at the same time, gotta love them! :)
Much much appreciated! looking forward to the next one :)
10k USA dollars is my guess.
Just it and nothing else.
I would say probably on the order of 20k-30k usd.
@Mihály Tóth thankfully there's Wish
@Mihály Tóth Co.UK ebay has none for sale.... must be expensive.
Why are they so expensive
A high speed thermal camera!? I heard in a ToT video that those are really hard to get cause governments don't want you building a heat seeking missile.
Possible but there would be easier and more damaging applications
The cryocooler alone costs more than 10 MILLION metric dollahs.
@@annelisemeier283 could you give an example, i am really intrigued by it
@@aleksastojanov4033 heatseekers on missiles get destroyed when the missile explodes. You can use them as triggers for IEDs or to spot concealed enemies, both of which (more the later tho) don’t necessarily involve the destruction of the camera and can still have devastating effects.
It's an interesting show of the status-quo of the US military dominance
I want to bolt that baby cryocooler onto my astrophotography camera! 😁 Also ++ to single flutes, it's basically the only tool I use now. Datron's cross-cutter is really great for roughing too, if you haven't tried it yet.
was thinking the exact same thing on the astrophotography aspect! 70K sure would beat the standard peltiers
Can you move the lens further away from the sensor to reduce focus distance?
Excellent suggestion
The lens attached to the sensor is screwed on and then held in focus by a little drop of glue. You can just break the glue and then you'll be able to adjust the focus to your heart's content.
@@tissuepaper9962 it might also be a filter too but less likely than on a regular camera, like the IR cut coating on cheap image sensors
example of how close you can get on the Seek Pro FF variant, with some of these cheap 10USD IR ZnSE or GaAs lenses.
a total focal view without any useless digital zoom, at around 5.5mmx3.5mm with a few stacked IR lenses ruclips.net/video/8NGalm8VFbQ/видео.html
1.25mm x 2mm resistors.. fitted on a microscope rig, but on the Seek Pro FF, you obviously have an aspect of manual focus, that useally have a viewfactor from around 15cm to infinity, and makes a big differene that you can piggyback ride on that manual focus with added IR lenses and Seek a clear picture with that manual focus, instead of pursuing it with variable IR lens-distance..
Very nice Marco, really loved the in depth discussion and view inside. We can always count on you to find interesting stuff we cannot get our hands on ourselves!
You might be able to bring that high-speed MWIR camera to the US to film the Starship tests but you might have trouble getting it back out of the country!
ZnSe lens flip cover is a great add-on. What focal length did you choose?
50,8 mm
@@reps Would a GaAs Lens work as well? I've got them laying around ...
@@marcus_w0 just check refraction and absorption for the wavelength range of your application, esp. IR only or mix IR band/Vis (for mid/far IR only GaAs starts to absorb again above 2um, not so much InP or Si or Ge, but are common)
I have a flir i3 that I got for peanuts, and I hacked the firmware so brought it up from 60x60 to 144x144 but the focal distance is a PITA for troubleshooting PCB’s it’s a fantastic idea,
@@djtopherau That's my idea as well. I just never thought about CO2Laser lenses and have a hard time to figure out their characteristics.
Wow, that match footage was amazing. The whole thing is nuts compared to the typical flir resolution. Thanks a lot, ITAR etc. I can't really justify a thermal camera right now, but it doesn't stop me from wanting one...
A reflective objective should work for thermal high speed microscopy. You could try DIY-ing a Schwarzschild objective out of a ball bearing and a concave circular mirror.
23:35 And your neighbour's solar panel is degraded by all the shadows from the trees as well as from the hot spots.
Yeah lol, depending on how those are connected they will produce as low as literally 0 W haha :P
@@Basement-Science it’s not as bad with modern panels thanks to the bypass diodes or even module based MPPT systems like SolarEdge
@@niklas8476 More importantly is if you use micro inverters or the whole string tied together, with micro inverters it doesn't matter in the slightest if any panel is brought down but even with bypass diodes a tiny bit of shade will still produce next to nothing in a string on those shaded panels.
If you want to see the most complicated devices and contraptions on YT , and also get the most elaborate explanation of how they work , this is the best channel for it.. Look no further 😎
What I learned: Thermal imaging cameras are still much too expensive to just have sitting around in a normal, non-professional household where they're not needed for anything, but just used for fun.
I never new the 9Hz limitation on Flir cameras was a legal thing, I always thought it was some sort of technical limitation of the sensor... Great video! and great idea with the tiny added lens on the front end of the hand-held camera, I must try that!
In IR, airplanes stick out against the sky like... a glowing white thing against a jet-black background. Gubmint is worried if they sell people high-FPS thermal cameras, someone will stick the sensor on the front of a missile and start shooting down planes.
@@TOASTEngineer What framerate would be required to make them dangerous? Can't they just put multiple cameras together and trigger them with small time offset to get higher frame-rate?
@@TiagoTiagoT Sounds like it could work. Could also just buy a sensor that isn't from the U.S. It's the government, it doesn't have to make sense.
@@TOASTEngineer the jurisdiction it falls under is ITAR, if you want to look into this further. Same with precision GPS used in surveying. You can’t buy a GPS that will work at sonic speeds d/t the risk of repurposing these chips for military use. I have wondered if some enterprising coder wanted to tweak the firmware of these devices…
@@TOASTEngineer seems pretty stupid to me. anyone who can get their hands on a tracking missile could easily get a good infrared sensor.
How you find these amazing little trinkets always amazes me!
I am trying to get my hands on a stirling cryocooler for a few years now, id say around 600-1200€ depending on the condition
That was very interesting video Marco! Keep producing great content 🥰
A most wonderful end to an informative video. Great stuff.
the doggo swimmers were BY FAR the best part of the video
.
more doggos please
Wait, did you just use a stainless high-vacuum-cf-component to prop up a hp-3458A... What have these things ever done to you to deserve that XD
Saw that too,
Maybe Marco will move to vacuum insulation for his next voltage standard?
Thanks for the new video. Always entertaining and most enlightening, although I understand only half of what you say, after watching all your other videos many times while waiting for the next one to drop, I think I am actually starting to learn a few things.
Awesome video! Always happy to help. :3
Very nice! I especially liked the "teardown" of the new daily driver. Not wasting anybody's time here! ;-)
Nice camera and work getting it going! Another alternative to capturing the digital video would be one of the Pleora iPort PT1000 models (there's an RS422 variant with the right connector, even), which can be used as a gigabit ethernet camera - though this could be a little too low bandwidth for your highest framerates. I've got a somewhat similar camera with an equally hard to decypher command scheme that I got capturing through one, but I haven't yet been able to work out a usable set of commands to do the FFC, adjust gain settings, or map the greyscale output to color or otherwise.
As your camera likely has similar thermal sensitivity, if you move your head outside of the autoranging ROI and exhale into the frame, you can probably see the heat from your breath, which is pretty neat looking. Heating your CNC chamber slightly or cooling the air in the airline to cool the workpiece even a few degrees will probably give you a visualization of the airflow around the workpiece with a camera this sensitive, could be worth a look!
The dogs clearly are the secret stars in these videos.
Nice to see you in action again.
I'm guessing the cryocooler costs like 5-10k dollars.
If the cooler cost 10k I dont wanna know how much the camera costs.
@@_who_cares_1123 500k easy.
@@youkofoxy I think 150-250k roughly... 500k seems a little much.
There was a Stirling cooled portable refrigerator that used helium as the heat transfer medium sold by Coleman for around $400 dollars. It was better than freon because any tipping of the compressor drained the oil into the condenser and made it unusable for 24 hours. It was manufactured by a Japanese company whose name I've forgotten.
Very nice. I used to work on military aircraft that probably used a similar thermal imaging sensor at it's core. The biggest issue we had would be calibration failures, and removing a 350lb camera gimbal from the nose was a pain to say the least..... Lens actuator broke? Replace the entire unit. Wish I had one mounted on top of my truck though sometimes.
That was super interesting. Thank you
very very nice, thank you for the idea
Great video, thanks for your sharing!
Awesome video, thanks.
That's so much nicer than my thermal camera, no need for bottled argon to feed the cryocooler and a higher framerate. 6 minutes isn't even too bad of a bad cooldown, guess one will have to go onto my 'to find' list...
this is such an amazing camera!
Every word he says makes this crazy camera sound even more expensive
you are a legend!j I know nothing about what you are doing and love it!
Love your videos such cool technology!
Great video! I have an older FLIR, the possibility of a high framerate seems very useful. Did work for Swedish Match developing matchheads, a fast thermal imager would have been rather useful. Used a Casio Exilim Ex F1 (discontinued) to film the experiments up to 1200fps.
For relatively cheap 25fps thermal camera I can suggest the infiray stuff T2L e.t.c. Probably the same line of sensors used in HT-301 mentioned here.
my phd is based on a survey from a telescope which used a similar ir detector. i love when tech has such a range
Now finally an ad I liked to watch. JLCPCB outpost in Germany? Perfect! Now move the whole aliexpress to Europe :D
i have also got a camera in the same class as this one. mine is a Flir Thermacam SC3000, but i did not get nearly as lucky as you with connecting it to a PC...
but appart from that mine is working beautifully with the Composite output and the Cryocooler. Someone on EEV blog made a adapter for mine to USB, might build one if i found some spare time...
Look at a lamp filament as you over drive it. Or a glass fuse, especially a slow blow fuse. Any thermal safety systems under overload conditions to figure out how they work. A vintage car turn light flasher unit might be nice to view in a animated GIF loop.
I ordered the lens using your link - nice thermal camera hack, good job. In other news a friend said he didn't get half of your jokes. I pity him, keep them coming :-D
that cover with what I assume is a co2 laser lens is really clever. if i had a thermal camera and/or a need for one that'd be an instant 3D print
Interesting as usual, thanks Repsy Boy
for about the same price (well, recently. it now skyrocketed for some reason) you can also get a HT-301, little bit higher resolution and much higher framerate , its a usb thingy you stick on your phone tho, not standalone.
but also works on PC as a webcam as far as i know (it transfers raw 16bit greyscale with telemetry data embedded in the pixels. it has a adjustable lens too. it uses a infiray sensor
not sure if joec's software supports it
I think the price went up due to projects like OpenHD
@@azimyth1542 You think so? I think someone is deploying screeners that pick people with fever out of a crowd, due to a recent novel virus.
Just typed HT-301 into google. 1st result is £999.99 on amazon. The HT-201 is over £500. The prices are ridiculous. No way i could ever afford one.
now i need to see the slowmoguys use a high-speed thermal camera on their channel ... thanks for that
I like the look of the RS232 connector on the camera 👍
Hey, have you ever seen clothing that is "IR proof"?
I have to watch your vids minimum 3 times .... my laughters make it IMPOSIBLE to follow the content .. lol
20:45 IIRC there are 8 pole relays for Gigabit Ethernet, are also somewhat small.
Burning with envy here in Brazil. Maybe some day we get a local branch of JLCPCB too? Our standard customs is infuriating. No thermal imaging to demonstrate that, though.
closer focus might be possible by constructing some bellows or extension tubes (used on optical cemera's, but not containing any elements, they simply increase the separation from the lens to the focal plane, thus preventing focus to infinity but permitting closer focus) basically light proof (in your case might need a bit more than light proof) tube to move the existing lens further from the sensor, a quick google should find plenty of info on their use for optical macro
I have never before seen such crispy thermal imaging
so smooth yet still clear
this camera has to be high range tens of thousands of dollars new, right?
even $100k's maybe
thermal imaging is still very very expensive, and this one is so nice
Marco bent that transistor fearlessly
I NEED MORE VIDEOS. IVE EVEN WATCHED THE UNLISTED CUTE PUPPY VIDEOS. I NEED MORE
From experience with a similar Stirling Cooler, also used for an infra-red sensor, about £8500, so around €11000
Another great budget Handheld thermal camera is Infiray C210 (at least for me).
I guess you got some inspiration on my blogpost about the Mosaic core and switching the USB ? :D
Marco I have a vid suggestion, can you make one about cleaning lasers? The ones used to clean rust pr paint off metals? How do they work?
Smarter every day could do with one of these. if you can lend it out. would love to find plans for a cold end. 3K$ spares or repair. Thanks for describing the parts .that was some crossover cable, dedication and focus, nice work.
In this wavelength range, calicucm flouride lenses work fine.
I love this channel
Guess I'm fortunate to work with Tau 2 cores (640x512) at work here in the USA, at the cheap cheap (lol) price of ~10k+ USD. However, after seeing the thermal sensitivity of these actively cooled sensors I must say that a microbolometer is not always the best solution!
Thanks for this vidya :D
Im glad you protected your dust!
aw those dogs looked so dam happy :)
I was one of the early German users of Ricors military cryocoolers for high-Tc superconducting sensors. It was not very easy in the early 1990ies to get one of their cryocoolers from Israel.
That jlc outpost is like 10km from my hometown.... what are the odds :D
What qualifies as munitions in the US with regard to lasers and imaging really does but a huge damper on what's worth pursuing.
As with all your videos, I press Like, then watch the video. Sometimes more than once...
The colormaps are ass, consider using perceptionally uniform maps, or at least turbo. I couldn't tell from the video, but just in case, the flat side of the plannar convex lens should be facing the converging side of the rays, aka the object side; the convex side should be facing the original lens.
It would be interesting to do infrared Schlieren imaging for the ultimate supersonic wind tunnel tester.
marco, if you look at your graph at 13:56, you can see a blue peak at 3.3 micro meter (near h2o) : that's ch4 (methane). your camera seems to be able to detect it, try with a lighter, normally the natural gas (mainly ch4) should be visualised as black.
but lighters are normally butane, not natural gas. so his best bet would probably be to run a gas stove without lighting it (only for a very brief period, ofc!)
Most pocket lighters are butane aren't they? Probably not very pure though.
Video recording works on the flir e4 as a webcam. I've recorded it to my phone.
Speaking of thermal macro... I have a Seek compact pro smartphone thermal camera. After dropping it and attempting to put the lens back on incorrectly once, I accidentally damaged the focus stop built into the lens housing. So now the lens has much longer travel, and can focus from far beyond infinity down to 5cm... This is probably the only time I'm actually glad I broke something lol
Very cool!
Great video! And thank you for not testing the camera's methane detection capability.
That banggood camera is identical to my Bosch professional one
I cannot believe you just posted this.
_"...if genius me was not holding it directly in front of the screen."_
We ALL make mistakes like that once in awhile...😉
Whats the UHV flange assembly for, apart from a thermal insulator ?....cheers.
that pumping bulb looks familiar *lemmyface*
miniature cryo cooler? I'm guessing $35K new. maybe they're cheaper these days?
i worked with a 20k one last year but it was beer-can sized so i'm assuming they go up in price as size decreases.
omg Jana what a small world
2:14 Yes! That’s what I was hoping for. So cool 😉
What about using a laptop with an external gpu enclosure for using this portably
You're brilliant. =)
Dogos wore the best :D something about cameras but that got ignored :D
Lovely content really :D
23:30 With that much shadowing on the PV panels, your neighbor should be using panels with integrated microinverters.
When my wife heard your voice she asked.. is it a computer speaking?😄😄🙋🏼♂️
dogs reached a critical internal temperature. literally laughed out.
I hope I'm not the only to notice the Keysight 3458a in the measurement stack, how many strings did you have to pull Marco?
14:25 I think that would be a worthy experiment! LOL
I don't know how many got the joke. I love your humor.
What's around the video frame on the monitor that you are hiding with the black/grey frame and hiding the software for most of the time?
