Don’t listen to those who are giving you a hard time about your English. Its clear and easy to understand. Anyways, I am happy to see your video is gaining some traction. Your hard work and dedication of creating quality content has paid off.
Giving constructive and useful corrections is one thing, but only complete idiots would insult someone for trying to learn another language. Lets see how good their French is before they criticise.
@@cda32Yes, mediocre mentality.
Even French did it.
Always the first ones to attempt to shoot you down, and I say that as a French.
It's not easy to understand but it's not difficult either
@@H0kram particulary french and only them did it, me to i don't understand why french people are always in judgment for foreign speaking, as french i suffer it too
Fascinating, thank you. Merci.
I don't care what language it's in - I just want to see the insides of stuff like this!
Absolutely, how does it matter if its Ada or C. Its the algorithm after all.
I agree. Especially for someone like you to get excited, a plebiscite like me knows its really special. Haha
Your channel is also great!
if you dont speak french, use subtitle... translates very well. keep up the great work. i love you videos!
Don't listen to those haters. You have a unique part in your hands, and it would be so cool if you could do anything to dump something. Even if the FPGA/netlist is protected maybe we can crack it one day! You did a GREAT job! You have something in your hands that is fascinating. Put all your effort into it! Good work!!!!
👍
I had an exchange on Reddit with someone who claimed (quite convincingly) that he was in the original design team. There are no FPGAs on that board. According to him those chips are ASICs .
The purpose of the gold was to prevent corrosion during long term storage, not radiation hardening. Operating in a nuclear contaminated environment was never a requirement for the Jav.
Yes, the sensor is a gyro. Beware, it has some pretty toxic chemicals in it. Maybe too late, since you have probably already opened it.
Reverse engineering machine code is not that difficult. There are many tools for this. You can't arrive at the original source, but you can absolutely understand structure and algorithms based on statistical methods. That said, micros with internal flash would have their JTAG fuses burnt so you can't read anything out. As you noticed, there's no external flash or EEPROM because they would be difficult to protect, so they probably opted for one-time download of everything from the CLU to the missile. This could happen during the initial cooling of the seeker, which took about 3 minutes in the old models like yours.
The Jav is a relatively slow missile by design and does not require that much power for steering (unlike the TOW). These op amps are used on a variety of platforms for this exact purpose. It's their main "raison d'etre".
And, finally, Russia, China and Iran likely already know everything they need to know about the Javelin. They have dedicated teams for reverse engineering US weapons that fall in their hands, just like we reverse engineer Russian, Chinese and Iranian systems that happen to fall in our hands. We brought a captured Russian "Krashuka" EW system from Ukraine a year ago for "market research" 😁
Well a thin gold layer wouldn't do anything about radiation, so I don't know where that comes from. Probably because rad hardened systems are generally high quality.
yep big VLSI chips are ASICs (VLSI was a big player in pre-FPGA asics). No code or flash needed, everything is in the metal layer(s) which interconnect standard cells.
Where can I see Russian and Chinese reverse engineered stuff?
Yes you’re right concerning the ASICs, I suspected that in my second video as all markings are different.
@@LanaaAmor In the USA, in a military lab, if you have proper clearance you can, for sure.
Great videos, and you are very fluent in english! Just ignore the trolls. Keep up the good work!
The answer on sensitive information makes sense. I've trained and used the javelin system during my time in the Army. The CLU was secured with other unit secret equipment, but the missile assembly was handled like any other explosive. You're probably correct about the CLU upload prior to launch, but I remember it happening very quickly and the CLU switching over to the missile's computer for final input. That was perhaps the most interesting tear down I've seen yet.
Without knowing French law, I highly doubt he will have any issues with showing this information but there's nothing stopping a government from claiming that showing this could cause military harm. Then you have to defend yourself in court, which in the USA, sucks even if you win your case! If anything, he might get a takedown demand letter. I just couldn't see prosecutors wasting their time on obsolete tech.
Very interesting and unique content, been watching for a while, and really impressed with both your knowledge and the amount of cool parts you've shown us. Thank you
Your English is decent and has improved since the first videos. I have trouble picking up some words sometimes, but that's less than 1%.
Some people just hate weapons and dislike every video about them, not seeing the engineering marvel that's sometimes a part of them.
Thank you for your work. I think your English is perfectly fine. There are lots of people around who just want to piss you off or to make a joke their friends would find to funny.
Je suis français et je parle anglais couramment, je n'ai eu aucune difficulté à vous comprendre, au contraire. Cela m'a un peu amusé au début mais ça ne pose aucun problème. Merci pour toutes ces vidéos !
Hey, first of all thank you for your Javelin Video which is the best video I have seen on youtube in the Engineering Field and your English is very good, clear and easy to understand, we support your Hard Effort and please please make your videos in English so you will attract more people here.
Michel, thank you for making these videos. Quite fascinating. It is really interesting to see how some of this technology works. I am a native english speaker and your last video was perfectly understandable to me.
Great video Michel, I love the displayed avionics in the back, like other people in the comments have said just ignore the haters, Your English is better than us Australians! 😂 Keep up the great work cheers
Here is a reference to an article about the two axis magnetohydrodynamic (MHD) rate sensor.
Aske, V. H.
Abstract
The MHD Rate Sensor was designed to provide two axes of rate information in a small package. The instrument measures 0.7 inches in diameter by 1.8 inches long. It consists of a torus of liquid metal, located within a radial magnetic field, which provides a voltage proportional to rate about its input axis. The torus is spun at a constant rate and the inclusion of a two-phase reference generator permits demodulation of the rate signal about two defined axes. This paper discusses the theory of operation, design of the Rate Sensor for producibility, and achieved performance.

That's a friggin gold mine!
Michel, as a fellow owner of missiles, KEEP GOING. Your tech there is dinosaur as hell, and now gone to the point of uselessness in actual combat. They're curios at this point and I DEEPLY appreciate you sharing the teardowns with us.
Your english is actually quite nice, I haven't had a single issue understanding your talking about even highly technical subjects.
I'm always excited to see what else you post and when I saw this come up, I was THRILLED.
-Signed, the other internet missileman.
Hello Michel, tes vidéos sont supers, ne t'occupe pas des toxiques... perso les commentaires qui ne sont ni bienveillants ni constructifs, je ne perd pas de temps et les ignore. Continu à nous faire découvrir ces merveilles !
Votre anglais est très clair et c’est une excellente idée de faire des vidéos en Anglais.
Ya, honesty one doesn't really have a choice these days, the audience for English is just so much bigger than other languages. I personally don't really care what language it's in if there are subtitles, but lots of people hate subtitles
No worries, your English is sufficient to educate. I certainly enjoy watching your videos as there is a lot that can be learned from dissecting these items.
Your spoken English is perfect, and your French accent makes your speech a pleasure to listen to.
I think your English is fantastic. Much better than my French!
Je suis Français ne en France. Ton Anglais est très comprehensible. Merci pour le traitement approfondi des équipements aéronautiques et militaires!
The part about the code and looking deeper makes a lot of sense, it is not worth the risk. You are already showing more than most of us will ever seen and it is interesting. It's not worth getting pressured more about.
Mate your english is first class. also just subcribed last week , amazing content and detailed explanation s in you r videos . very interesting stuff sir !!!
Merci pour tes vidéos, ne change rien !
Your English is very good sir, and thank you for all that top notch information. Very interesting channel.
Love this channel, thank you!
Looking forward to part 3 (sensor disassembly)
Je viens de découvrir votre chaîne, très intéressant, bonne continuation :)
English isn't my native language either, and i understand your English very well. Great videos.
Thank you so much for addressing these issues in such a matter of fact way. Very interesting subject matter and having gone through your channel history I'm excited to watch everything you have produced.
You’re helping me with my (high school) French. Thank you! 👍😊
Michel, thank you very much for your previous video. I could perfectly understand your English. In fact, due to the French note I found it very pleasing to listen to it. Please continue doing such videos!
I'm a big fan of yours and your videos help me a lot.Thanks！
Dear friend, as like with the good music, these types of developments transcend the borders of language, and are part of the bond of an entire global electronic community that we are surprised and admire every time we witness works like yours. Kind regards from Argentina.-
Michel , bravo et merci pour votre chaîne très très intéressante , le partage de vos découvertes et investigations. Ne vous laissez pas atteindre par les remarques concernant votre accent , vos commentaires sont très intelligibles et leurs contenus regorgent d'informations. Donc persistez pour notre plus grand plaisir à tous. Le domaine que vous explorez est fascinant et je désespérais de voir un jour une chaîne comme la vôtre qui permet de voir les entrailles de ces magnifiques lnstruments , d’en saisir le mode de fonctionnement et de les voir revivre. De grâce.....continuez après vous être requinqué à Maurice.
Je suis marocain et je vous dis que votre anglais est excellent! N’écoute pas les commentaires negatifs
I have been watching for a while and have always understood your english very well!
Keep up with the informative videos ; let not language be a barrier . 👏
Hello, I like your Content, it goes deep regarding Information's and your English was never a Problem I would even think about, at the end I don't care which language is spoken, I care about the Content I See, I watch technical Videos even in Languages I don't understand at all with self generated Subtitles and even without !
Thankyou for the Work you do !
As someone who speaks much less French than you speak English, I absolutely appreciate your effort to provide this content in English as best you can.
The internet is full of opinions, and as you say, you cannot please everyone. I always think that these people should try making videos themselves if they are unhappy with what others are doing...
And I'm sure many of your viewers are repeat viewers and very much enjoy your videos.
Merci beaucoup.
Great works. In the age of AI I'm sure those idiots can just use the auto-translation in youtube if they are too dump to understand you. Merci
Your English is excellent for a non-native speaker, and is better than many native speakers.
Not having code in non-volatile memory has many advantages; the code cannot be downloaded from the wreckage or captured unit, the misslie cannot be used without the code, and the code can be updated without modification to the missle hardware. The disadvantage is it takes time to load the code onto the missle, but this could be done before the launch platform takes off it the missle remains powered on.
I have seen up to 16 layers inside a PCB. They can be hard to debug even if you know what's inside ahead of time.
I don't know English very well and can't judge other people's accents. But familiarity with technology is great for understanding other languages in technical videos. Thanks to you, I even improved my English skills. Good luck and thanks for telling us about these wonderful things!
Michel, your English is excellent as are the videos you produce. Thank you.
Such a great channel. Continue doing videos. One of a few interesting youtube channels nowdays. Sending love and greetings from Poland :)
Your English and video was great, understood 100% of it easily. As you say, you can't please everyone. Ignore those who complain, as hard as it is. They are the kind of people who complain about everything! Au revoir.
As an non-native English speaking software engineer working with other non-native English speakers, I think your French-accented speech is very nice and refreshing.
Your videos are the best. I have absolutely no problem following you without knowing hardly anything in french and without needing subtitles. I have nothing to criticize you for. What is more important is to know how much your time and effort into making these videos for those who really enjoy avionics is appreciated. I am grateful, and look forward to more great content from you.
Bravo pour le fait de faire les vidéos en anglais, c'est beaucoup de travail. Merci pour vos vidéos qui nous montent du matériel de qualité militaire et spatial. On y voit aussi l'évolution de l'électronique au fil des années, c'est génial. Et on voit de la mécatronique ce qui est très rare. Malheureusement c'est surtout les militaires qui utilisent les technologies les plus poussées pour leurs besoins de précisions et de fiabilité et en même temps, ils ont les budgets, le matériel et les personnes pour. Et vous faites l'effort d'acheter ces objets et de nous partager vos connaissances. Merci Michel.
Keep it up! Love your videos love your English accent even more❤
Perfect - answer them in French! That‘s the way!
Thank you for following up
Merci!
Your videos are excellent.
No music.
No BS.
Time enough to look up parts (press pause!) and in general I agree with the interpretation you provide on top.
Thank you!
Thanks for post man, i appreciate it! Also thanks for adding English subtitles :)
Fabulous! It's surprising how similar the circuits are to pro-audio cards of the same era, dsp processor, adc, fpga. Can't wait to see the teardown of the gyro.
bravo pour votre travail et vos vidéos. Elles sont super
I think your English is excellent, and personally I find English being spoken with a strong French accent to be awesome to listen to. My former manager (still a coworker) is French (born and raised) and while he has been living in the US now for 8 years. His accent is still very strong and its something I also look forward to hearing. He is one of my favorite people in the world. 🙂
Please don't stop doing your videos in English. It is a pleasure to hear such technical information spoken with a French accent. I will still watch all your content if it is in French, but I will gain more from it if spoken in English. 🙂 I guess I am allowed to be selfish at least once and a while! lol
Great job！
Your English is easy to hear, in fact. I've enjoyed listening to you speak - it has helped my understanding of French, and I'm here to view your brilliant content - how somebody sounds and looks is irrelevant to me. All the best, Beamer.
Bonjour Michel,
I have been following your channel for years, never had an issue with understanding your engliah and always felt that your french accent was very charming.
Thank you for all your hard work over the years. I can never get enough of your unique subjects which entertain and enlighten me with each and every video.
-Ray
Hey Michel, your English was really good enough for 99% of us to understand without an issue, don't worry about the 1%. You can't make everyone happy.
merci Michel , ne vous préoccupez pas des grincheux , vos vidéos sont géniales , encore un grand merci pour le temps passer a nous faire découvrir toutes ces merveilles.
I haven't watched the whole video yet - I had to stop and write that your English and accent is nothing to apologize for. I have learned many, many things watching your teardowns and following your reverse engineering...and I sadly never learned French. Thanks for sharing the rare insight you have into these systems.
Honestly I am grateful you make these videos accessible in English. Accent never bothered me Everybody has one!!! Great work please keep it going! Peace and Love
Its pretty amazing the board doesnt have any EEROM, Flash memory or any memory chip storing the firmware. Its actually programmed on launch. Really cool
To be frank, I'd simply shadowban anyone criticizing your language skills. You don't need people 'bothered' by that to have any influence.
I had no issue understanding your english, some people just like to complain and put others down any slimy pathetic way they can.
As for this video, I appreciate the subtitles, my french is NOWHERE near good enough to keep up! :) But I appreciated the challenge!
Merci beaucoup!
Bonjour Michel.
Forget the wannabe English teacher trolls. It is a privilege to witness these wonderful circuits you provide us with rather than focus on your English that I totally understand. Beats me how anyone doesn't. As an English speaker, I actually enjoy listening to you speak French while the subtitles are running. What more could I ask for?
I wish you a safe journey and a happy stay in Mauritius.
When you measure laquered circuit board, you can use "production sharp & hard pins" attached (even soldered) to measuring sticks. Those pins are spring loaded, so they stand much better than normal sticks. Sharp pins can even punch through cable insulation.
Vous êtes formidable, monsieur
Спасибо! Очень интересное видео.
Hi, Your english is phenomenal for French guy. For real. Thank you for yours content and I wish you all the best. Merci
Don't listen to the trolls and idiots about your english accent. Congrats for the videos and the great work. Its great to see technical videos like that. Merci Michel
Merci Monsieur pour cet excellent travail, qui ne triche pas. C'est si rare de nos jours.
Your English is easy to understand.
Lol, dumping the SRAM is like downloading more harddisk space from the internet ;-DD
Hello from Detroit! I like your videos and your accent is nice. stay proud, friend!
О Сенсею, дякуємо Вам безмежно за ці краплинки інформації по ремонту, та особистих інженерних рішень!)
Very very useful videos.
Merci pour cette vidéo
Le français est-il un grognon ? Je suis nul en anglais, mais j'apprends grâce à ta diction lente, c'est appréciable. Et que les grognons retournent dans l'obscurité.
Je suis prof d'anglais technique, et je trouve votre anglais d'un bon niveau avec du vocabulaire, des expressions grammaticales etc,... bravo.... même si l'accent reste "perfectible", N'écoutez pas les petits orgeuilleux qui se la pêtent, leurs odeurs empestent sur les réseaux sociaux!!
Thanks for posting these videos!
I'm curious, do any of those instruments behind you have radium dials? I'd be interested to see if they're radioactive
Zдравствуйте Uvажаемый гражданин Франции .Увидев множество циферблатов за Вашей спиной , хотим Вас предупредить.Об опасности радиоактивности .Возьмите дозиметр и проверьте фон , многие приборы Опасны для здоровья .Берегите себя ! Неполенитесь - потом спасибо скажете , циферблаты светятся в темноте и многие срдержат изотопы для этого эффекта .Здоровьем военных пренебрегали по причине самого военного аппарата , несшего более важные задачи. БЛАГОДАРИМ ЗА видеоразбор , привет из России .Франция GUT !!!,Париж , Эфелева башня , Наполеон . ОК !
Надеюсь он это прочитает , иначе будет ещё долго фонить в коробке
Наверное прочитает когда - нибудь , так то не страшно очень ? Пилоты и Водители , диспетчера часами внимательно дежурят у таких приборов и НИЧЕГО им не делается , даже раньше на пенсию уходят как известно . У нас , например полно пенсионеров - лётчиков , а посмотришь ему 40 лет , вот так .А прикиньте Космонавтам - наверно за один полёт сразу пенсию дают , Вот там ренгенов то НЕМЕРЯНО .Какая наша планета Заботливая , оберегает своих ДЕТЕЙ , укрыв своим одеялом от вредных лучей , а мы ЕЁ Любим за ЭТО . Даже праздник говорят есть - день ЗЕМЛИ , непомним какого числа .😺😺😺☡
Did anyone in the comments thinking they are going to build a DIY portable missile by buying components from Mouser and assembling it on their own bench?
Military material has billions of dollars in investments, patents and the main thing: "If it can't be used, it must be completely useless to my enemy"
You buy some parts and get on the FBI’s list immediately.
Merci beaucoup pour votre contenu francophone! J’aime écouter le français parlé. La place des trolls est toujours sous un pont ;)
Great !
Hey, as an English speaker I apologize for those who are so narrow-minded & shallow to criticize you for your accent. I'm just grateful for your video content and, that most of your videos are spoken in English. I really don't have any trouble understanding you. The fact is the internet really is just a cesspool, it's one of the few drawbacks mixed in with the infinite advantages & useful information it brings to the world.... I'm sure you notice all the people who immediately stand up for you and call out the dirty trolls who want to criticize you. Don't ever let it discourage or, bother you in the slightest...
Same for me, 4% of my watchers are located in France.
Honestly not sure about the comments complaining. The first part was clear and well narrated.
I liked your content keep ot coming
Le bon accent français m’a bien fait rire. L’important c’est le contenu ! Je viens de m’abonner. J’attends la suite avec impatience. Continuez en anglais au vu de vos chiffres !
your english is understandable please continue
Parabéns pelo bom trabalho que tem feito, para mim seu inglês é excelente, dificil mesmo é entender os americanos que falam em 3x.
Your English is perfectly fine, just ignore the people that complain about it, I’m sure most of them didn’t make any effort to learn a second language, they aren’t aware of all challenges associated to it.
YOU ARE GREAT!
Hi. I have never been unable to understand everything you say. Your English is excellent. Anyone who complains should clean their ears out! Or maybe they are the one with a problem.
So don't listen to the complaints...!
Your english is perfect. Its was very pleasant to listen to. Not sure what these people are talking about.
I, at the very least would apply some potential to the DC rail to see if it draws some current, maybe one logic IC will at least get warm.
Great work, your English is fine.
Moi j'ai aimé votre vidéo et votre anglais est tout à fait respectable, vous parlez mieux que des collègues à moi qui bossent pourtant en anglais tous les jours.
Internet et le savoir partagé, c'est en anglais. Les rageux pourraient s'inspirer de vous si ils n'étaient pas médiocres et bas de plafond.
I am from Hong Kong. My English is also bad and with heavy Chinese accent. I enjoy your English with French accent and your video too
