content: Vipitis,They will be Faulhaber coreless motors or similar high quality equivalents. Such motors are pretty much the standard for high end compact motor systems and they offer a large range of diameters, lengths and gearbox options.https://www.faulhaber.com/en/home/Maxon is another brand of coreless motor commonly found in high end cameras.https://www.maxongroup.com/maxon/view/content/product-overviewThese types of motors are often modular in nature. The designer may choose a suitable electro-mechanical specification, diameter, length and options to integrate the motor into the design. The options often include compound gearboxes and position sensors. Excellent motors, but also quite expensive, as one might expect of such fine engineering.The FFC shutter can be driven by a coreless motor or a rotary solenoid. I do not know which is used in the Txxx series.FraserEdit: the term “brushless” crept into my comment above. I meant to say “Coreless”. Now corrected.

Well what to say ... far exceeded my expectations, incredible images that I would never have believed. I got both the hti immage app very good but a little simple and with few options. an important thing that I was able to evaluate is the remarkable options on the thermviewer app, much better but for a fee, for sure I will buy it.On thermviewer I was surprised because someone said that he does not have the possibility to perform the manual tuning of the images, instead you can even if you have to learn how to use it. In this way, you can get much more detail on the points that interest you, just like the flir professional thermal imaging cameras. I have nothing more to add besides the fact that I feel I have made an excellent purchase !! Very good HTI inxtruments ... :-)Ps- Sorry for the not perfect writing, I use google transalte

As close as the lid structure is to those wires it's a wonder I haven't done worse.Without taking a fresh look at mine under the microscope I was thinking that maaaayyyybe it would be possible to straighten yours out and, with a fine wire extension fitted to a soldering iron tip, solder them back together--IF they were merely broken somewhere in the middle. But it looks like some of yours are pulled off of the chip and your 1mm scale is a quick wake-up to the potential fantasy of that notion (0.01" between wires!). Need to get smaller piano wire.Sometimes you can do things with crude equipment but this probably does need the proper equipment for the job... which I don't have.

It is on the 6 pin 0.1" header.Same signal line, the core analogue output.You could also use the BNC socket if you no longer wanted the 'with graphics' version. For that extend the green & black to a 0.1" socket and replace the header facing the other way.There was reason behind the apparent madness of fitting a 90° header facing out that had to be cut off to fit in the case.Bill

LOL. That was the remains of my original attempt at trying this, just turned out to be a power output.

content: I already own at least six of these and even have the chassis of one in my spares stores. I was not sure that anyone would be interested in a tear down of another BST camera that basically used the same Raytheon kit of sensor parts as the ARGUS 2 that I previously documented on this forum. Sadly these BST based cameras are non radiometric but that is not a problem for those wanting such a camera for observation situations. Some models are fitted with a visible light camera and/or a pyrometer for scene temperature measurement. Whether 350 Euros for a unit is a good price is a decision for the buyer. They have decent Germanium lenses in them but the front lens condition can deteriorate over time with constant exposure to water. Damage is seen as heavy scratching or flaking away of the hard carbon AR layers.Fraser

FLIR Lepton Breakout v1.3 Problems - Page 1

timestamp: December 24, 2019, 02:17:48 am
content: Several years ago I bought a FLIR Lepton with the v1.3 breakout board from GroupGets. I'm finally getting around to trying to use it and I can't get the video data out of it. I've been using the documentation fromhttps://groupgets.com/manufacturers/getlab/products/flir-lepton-breakout-board-v1-4and it seems like I should just be able to turn it on and read the video data via SPI. I am able to communicate with it via I2C and get things like the ambient temperature, which seems correct.When I read via SPI I get what seems to be garbage data. The ID isn't the packet ID and the CRC field doesn't have the correct CRC. The data doesn't seem to be entirely random, but I can't make sense of it. The problem may be that the documentation I'm using doesn't match the board, but I can't find anything about the v1.3 board and sensor that came with it. Some of the commands listed in the documentation don't work, like getting the video output format so I think the module I have predates the documentation.Has anyone here successfully used this module or does anyone have any ideas about why it might not be working? I've attached a sample of the data read from the camera.

You might just have been unlucky with the particular micro SD card or adapter. Try another SD card. I recommend SanDisk cards.Fraser

My changes can be found here:https://github.com/rsend/libseek-thermalAs I'm not a software engineer, I can't possibly hope to match even a subset of joe-c's excellent work, but I did add the following functionality to the seek_viewer example according to my own usage model:- Cycle through color maps with the 'c' key- Manually adjust brightness & contrast using w/a/s/d if invoked with "-n 1".- Rotate through 0/90/270 degrees with 'r'- Move the window with arrow keys (currently only tested on Ubuntu; apparently scan codes for the arrow keys vary significantly across platforms and frontends)- Scale the output using + & - (i,e Shift + "=" for plus and just - for minus). Numpad +/- return different scancodes, not implemented at the moment but easy to add if desiredIf you find this useful and have a chance to test it on other Unixes, please comment on what works / doesn't. It'll probably be a matter of keyboard scancodes.Enjoy,Rafael

content: Hi everyone, I'm working with FLIR camera mostly (lately also with Thermal Expert Q1, just approach), and I would like to see thermal view from the FLIR camera in HoloLens. So I guess this could be possible via Unity3D engine, so I'm trying to figure out how to interconnect Thermal camera with Unity3D.Does someone have ideas how to do it?Any suggestion?Thanks in advance,regards.

content: Thanks for reply.Well I want just the view that can see the thermal camera, for example FLIR camera see into Research IR software. In some website (I dont know it I can mention it) I found an example made with Thermal Expert Q1 with Unity but doesn't seem to work, there is MFC folder and Im not able to run it...Anyway I just want to show in Hololens (that actually is a pc screen) Thermal image from thermal camera. So that's why I thought Unity3D, since it fits with HoloLens through Holographic mode.There are also some samples in Unity that can have access to the webcam of the computer through a simple script. So maybe There could be a way to have access to the FLIR or whatever thermal camera.Thank you very much!

content: You can email Thermal Expert and ask them for the appropriate drivers where you will get a precompiled library and C header files for it. (A DLL file with the drivers is probably also with the PC software for it, you can open it in a decompiler to see all of its API calls). But know that the driver is very basic and will just simply spit out an array of float values with the temperature. You will have to turn that into a usable image yourself.As for Unity as far as i know that mostly runs C#, so you will need to use interop to be able to call regular native code DLLs. Or alternatively create a .Net wrapper DLL for it.These cameras do not appear as webcams

content: Can you say something about your application? That, more than anything else, is going to inform any suggestions. If you're looking for high resolution radiometric imaging then $200 is simply not enough, but at the other end of the scale a people-counter can use quite cheap, low-pixel-count sensors.Buying new, you're going to be looking at something in the 80x60 or at best 120x80 pixel class - but assuming you can find one with a Linux driver may be a big ask. You have to be fairly lucky to get anything better for under $200, even used on eBay, and the likelihood ofanydriver being available is usually inversely proportional to the age of the device.

It is possible to trigger saving a clip from the camera itself but the acrobatics of it is rather odd and is not worth the trouble. One of possible use of this feature may be capture bursts of frames for subsequent superresolution processing.

However the hack was still valid and could be preferred for integration of the streaming into a custom application.Also rumors at the time were Win10 was expected to work with the original unhacked libuvc for Windows but I never tried that.

content: Hi all,I am new and I hope there is not a similar topic. If there is, please let me know where I can find it.I'm new to thermal imaging and I have to work with a FLIR A35. I need to save the pixels signal (that is proportional to radiance [W/m^2/steradians]) to post process them (I am not directly interested in temperature values). The signal I am interested in is called 'counts' on FLIR manual.I would like to extract the ‘counts’ with a free tool (directly with eBUS SDK Pleora or FLIR Tools for example). However, it was quite tricky to me, because on eBUS Pleora I was able to save only *.TIFF (or *.BMP) formats in which each pixel is 0-255 value (grayscale image, 8 bit). With FLIR Tools, I can extract *.csv data (right click on the image), but the data are temperature values only.Is there a straightforward way to save the pixel ‘counts’ with any free tool?Thank you in advance, any suggestion will be very helpful.Marzia

content: My FLIR SC4000 operates in the ‘World’ of counts and displays such if a calibration table is not loaded. The calibration tables on the SC4000 are selected from a default set created by FLIR or a user generated type. The calibration table translates the cameras counts to whatever temperature unit of measure is selected.Your camera is not a scientific model so I doubt that you can disable the calibration tables that convert counts to units of measure. I know of no software that will reverse engineer the temperatures back to counts.It would be worth contacting FLIR customer support and asking them if a counts output may be accessed on your camera. They are the ones who will know and be able to advise how it may be done, if feasible.FLIR ResearchIR provides access to the counts reading on my SC4000 but that is a very expensive softwareFraser

Well this sick TK was cheap enough to tempt me to have a play with it.The seller bought it as part of a job lot and suspects it is the victim of a failed firmware update. I cannot find any firmware updates for the TK though so that scenario seems unlikely. If it is a firmware issue it would have been either a failed hack attempt or self inflicted corruption by the TK itself.I will document my experiences with the TK scope hereFraser
