content: How To Convert Any Camera Into Infrared Thermal Camera Very Cheap But Useful Hack . Every Camera Sensor Has Ability To See Infrared i.e. Thermal Part of The Light But The Infrared Blocking Filter Inside Digital Camera's Protects The CCD Sensor From Burning With High Energy Infrared Light Such as Sunlight .Now , If We Remove The Blocking Infrared Filter The Camera Can Also Able To See Some Infrared Part of The Spectrum of Light ! Which Is Pretty Cool Because After This Hack You Can See Hot Objects With Your Camera Glowing More As They Emit More Infrared Energy & Many Other Things You Can Do Like See Through Some Clothes , Black Objects Which Takes Teardown To a Next Level !Even The Cheapest Seek Thermal Camera Is 200$ Compared To This DIY Which Can Be Done In Just 10 $ Including HD Video Camera ! Which Seek Thermal Camera Don't Have .Please Suggest Me Your Ideas & Improvements ,Thanks.# Watch Videohttps://youtu.be/IdJgxNVVrs4

content: I think the case is visible light blocking one and allows only ir spectrum..ive seen such plastics before...but they are very thini've seen pics of sensor like tsop1738 clicked with ir camera....the metal inside is visible as clear as trapped in crystalLol...the video is from the same guy who knows nothing about 0201 or smaller ledsDon't trust that youtuber...take him with a pinch of salt...he's what we call a "juggadi" in India ie engineer without training ...I was a juggadi too (until i got training from hightech inc and ignou) but i never lie, I accept I don't know the stuff when I don't

It's the same type of plastic you have on the business end of a TV remote.Quote from: Raj on May 16, 2016, 09:21:37 amThose look like bits of semiconductor stuck directly to the board and a bond wire attached to the top. Hey, putting that into an epoxy case costs money!Quote from: Raj on May 16, 2016, 09:21:37 amThere is no such thing as an engineer without training.

I used to work as a section editor on a UK magazine. I can state that I have seen, with my own eyes, letters from nutters that were handwritten in green ink.

content: Quote from: Raj on May 17, 2016, 05:05:35 amI think you misunderstood my point. An engineer, by the very definition, is a person with at least a Bachelor's degree in one of the fields of engineering. You can't just pick up a soldering iron and call yourself an engineer.

content: Quote from: Dave on May 17, 2016, 11:31:33 amI'd very strongly dispute that that is either the formal definition of an engineer or even a good working definition. It might be the legal requirement to call yourself "Herr Ingineer Pointy-head-boss Ing." in some jurisdictions but it doesn't cut the mustard as the "very definition" of an engineer.

content: There are always going to be engineers that are going to be lousy at what they do and there are going to be technicians/hobbyists that are going to be better at designing and have more knowledge about actual engineering than many engineers. The fact of the matter still stands, to be an engineer, you need to have a paper that says you are one.It's the same thing with doctors (the medical kind). There are going to be lousy ones and then there are going to be people without formal education in medicine that are going to know more about medicine than actual doctors.You can't just go around calling yourself a doctor without a degree and you can't go around calling yourself an engineer without a degree. Actual skill and knowledge have nothing to do with it.

content: The NIR part might be useful for really hot stuff, if it is dark in the room (so not much visible light) and the camera is really sensitive (e.g. higher than 3000 ISO setting). With a low cost camera the limit is likely higher - so maybe you find the hot soldering iron in the dark. you might also want to have a VIS light blocking filter (e.g. thin SI wafer) to get rid of background. Also some lenses might already block some of the IR, and not every NIR filter is easy to remove.I know of a NIR based thermometer that worked down to about 150 C, though more made for higher temperature like 500 C.So I would expect this to be of very limited use for electronics.

content: Quote from: Cerebus on May 17, 2016, 03:14:37 pmQuite. But it's annoying as f**k that you spendfourfive years studying to be allowed to legally cary a title that is elsewhere included with a bag of washing powder.

content: Quote from: Dave on May 17, 2016, 03:45:04 pmEngineer isnota protected title in many legislations. In the UK it's quite legal to call yourself an engineer without a degree, heck, without a single GCSE - Chartered Engineer is a different matter, that is protected. The association between engineer and a degree is not universally made.

content: Quote from: Dave on May 17, 2016, 03:45:04 pmUm, tell that to the poor chaps in the US that are driving trains for the outfits like CSX or Amtrak! Nobody calls them anything else but an "engineer".My job description also involves "engineer", but my uni doesn't even award those titles - I have a "Mgr" - magister, roughly an MSc equivalent.The only legally protected titles are some specific jobs like that "chartered engineer" mentioned before.Doctor is different, because that is apriori an academic title, most often understood as a doctor of medicine unless qualified more explicitly (doctor of philosophy, law, etc.). Engineer in English is a generic description of occupation that may or may not require an advanced degree (like that motorman driving an Amtrak engine).That in some languages and countries it is also an academic degree (e.g. in Slovakia technical schools award "Ing" for engineers and universities award "Mgr", even though it is the same type of degree) is not really pertinent nor generalizable.

content: The laws apparently differ from country to country. Here in Slovenia you are awarded with the title engineer (actually various flavors of it) by acquiring a college diploma in a field of engineering. I would have imagined the laws were in sync across the european union, but apparently they aren't.

content: Quote from: Dave on May 18, 2016, 07:47:03 pmThey aren't, at least not in the names of the uni degrees. The Bologna accords only specify how many years/credits you need to accumulate for which degree, but not what it should be called. That is very much a traditional thing between the schools and the US/UK style of degrees and the more "continental" ones derived from the German/French systems.
