content: Please stop asking questions that would lead to people making illegal and dangerous devices.Dangerous because they might prevent other people getting help in critical situations.In addition, if someone caught you using one, they might crack your skull - but that wouldn't cause me to lose any sleep. e.g.https://www.eevblog.com/forum/rf-microwave/are-there-any-online-resources-available-to-make-my-own-signal-jammer/msg3160220/#msg3160220

Or do they have to have the knowledge of graduate or post graduate?

content: QuoteI'm going to say "no."Things may have changed since I went to college (class of 1981), but my EE degree was very long on theory (calculus, physics, digital logic, semiconductors, measurements, analysis, etc) and awfully weak on the practicalities of actually building anything.Going through the textbooks will probably allow you to understand, in principle, how "your devices" work, and next to nothing about how to find a power transistor capable of amplifying a RF signal of the frequency and magnitude necessary to build a high power transmitter.

content: Quote from: novicefedora on July 28, 2020, 09:29:25 pmBecause you give no indication that you have either the knowledge or intention to use it ethically. Usually people asking such questions are up to mischief, or worse. So that's the way to bet.In addition, sooner or later another reader might come along and think "oooh, kewl, i'll do that" - and hurt a bystander. Thus I wouldn't post how to make explosives, nor how to use "naked" laser chips.QuoteWho cares what the answer might be?What will you do differently depending on the answer?

content: Why would you even need to ask how to build that "Wave Bubble"-device? The detailed instructions are right in the first search result...So I guess if you can't comprehend them, you're neither able to design or build such a device.Also, name me one legal and ethical use of a signal jammer outside of a proper shielded chamber.

content: Absolutely. Read all the undergrad textbooks. Then read them a second time. Better read them a third , fourth and fifth time to make sure. Maybe even a sixt, seventh and eighth time too.Then find some more undergrad books. read those too. at least 10 more times, then switch back to the first batch and do that a few more times. Keep repeatingthat'll keep him busy ..

I don't want to consult a psychiatrists because that would compromise my mental integrity. It could also be possible, something might be added in my food or drinks to make me lose conscious, which would allow them to anesthetize me.If you can't add anything helpful, just shut up.

content: Quote from: MK14 on July 30, 2020, 11:44:39 amI didn't claim there is an implant in my brain. I said ear or throat. Besides when 3 letter agencies have implanted something in someone, they would be monitoring that individuals every move, they might bribe the doctors and staff to show fabricated x-ray and MRI scan to deceive that there isn't any implant. You are trolling here, you are part of MI6 or MI5 moles here to spread disinformation. Psychiatry is a stupid profession, a person most valuable possession is their ability to reason, psychiatry exists to turn people into puppets and slaves. You should try the electroshock therapy sometime.I would also like to mention that if there is an implant in body, going through an MRI scan would either disable the implant or pull the implant out. So if a person claims the MRI isn't showing the implant, it's probably because it was sucked out. That is assuming the MRI was working as it should and the technician didn't just do a test of it's part moving.

content: Quote from: MK14 on July 30, 2020, 11:44:39 amThe very reason that the quote doesn't consider the possibility of x-ray or scan information being fabricated proves that you are spreading disinformation and psychiatry is a stupid profession existing only to turn people into puppets and slaves. The patient who is intelligent enough to argue that the imaging must be wrong or the implant was invisible, would have also been able to argue that the x-ray or scan information might have been fabricated, the fact that such a counter argument from the patient hasn't been mentioned or presented as it wasn't made is really the most conclusive proof of the psychiatric professions subversive motives.

content: Quote from: novicefedora on July 30, 2020, 12:15:18 pmThank you for offending a great group of people.QuoteA disabled piece of circuit will still be visible on an MRI scan. and if it would be pulled out (which most probably won't happen as the most part of many circuits aren't magnetic, especially if they are done to be implanted into some tissue) you would notice that. And you should be happy, because your problem would be solved, wouldn't it?Those sound like two very good points to get a MRI scan - you can only win. go on.As a side note - I also have an implant, but in my hand. No, not a piercing or something do decorate my body. I'm talking about a circuit that is able to send out and receive data. I even have photos where that was done.

Almost all parts of circuits can become magnetic when current flows through them but their magnetic power isn't that much. With the knowledge you are showing, I'm surprised you actually considered the possibility of it getting pulled out. I should be worried about that risk nevertheless, if it got pulled out of my ear region or throat region, I don't know what kind of damage it might cause.Can you show photos of your implant? What kind of circuitry is it, how is it powered, how does it receive data and what frequencies does it use?

content: Quote from: novicefedora on July 30, 2020, 12:24:37 pmThe quoted TEXT, is only giving a generalised example. It is not supposed to be trying to cope with all the millions of possible, real life variations in things.E.g. I might say to you "Turn the POWER Switch OFF, Please".There are all sorts of situations that this could apply to. But there are rarer ones, which I might not have considered. Such as the switch might be broken, or you can't find the on/off switch, or even that there isn't an on/off switch for this device.Just because I didn't cover all those thousands of different (unforeseen) options, DOES NOT mean, all of the type of person that writes text like that, is bad. It is just because there are limitations, on how much information you can convey by written text messages.I would suggest you get professional help. Ideally via professional Doctors, who can help the situation.If that is not possible, in your circumstances. Then confide in your most trusted, reliable and wise close relative, friend or work colleague.

In my implant there is a pretty substantial antenna, so basically a coil. The forces aren't enough to be even noticable.Pics (one with the syringe before the action and one after its done):https://drive.google.com/drive/folders/1qcJt0dKuBP1nqvuuu6NFEB4ue4_Hi-go?usp=sharingI was certain that I took a video while that thing was put inside me, but I can't find it.

content: Quote from: MK14 on July 30, 2020, 11:44:39 amI knew two different people since gradeschool who later developed schitzophrenia in their early 20s and this is exactly the sort of stuff they talked about. One of them was posting prolifically on facebook back when I still used that, as in every 10 minutes for hours at a time about the various people tormenting her and secret agencies spying on her, it was really bizarre. The other one I knew thought his whole family was in some kind of conspiracy against him, occasionally he would be on medication for a while that settled him down but it also took all the life out of him and made him a bit of a zombie while he was on it. Schizophrenia is a really scary disease, people who have it tend to resist any form of treatment because they genuinely believe that they are sane and that people who are trying to help them are out to get them.

content: Quote from: james_s on July 30, 2020, 06:51:19 pmIt's sad, when things like that, happen to people you know. Especially, if you knew them, before such episodes, started. I would guess, that the modern era. With many things open, 24 hours a day. Easy/quick internet searches, even if the search terms are crazy. Massive anonymous communications medium, such as this forum.It could make things like that worse (but there are also ways, it could make it better).It is not immediately obvious, which wins out. I.e. If modern times (now), is better or worse than say, 20 or 30 years ago. As regards, mental health and getting mental health issues sorted out.My understanding, is it has never really been any good (for the patients), at any time, really, so far.Maybe, in the future, diagnosis and treatments, will get better. One has to just hope, I guess. It seems to be a relatively neglected part of society, medicine and can cause sometimes negative feelings in others, if they know about other peoples, mental health conditions.There is still varying amounts of stigma/negativity, both at the individual level and society level, about mental health and/or seeing/dealing with Psychiatrists, and other mental health professionals, such as Psychologists and Mental Health Nurses.Both me, my imaginary friend, and all my other alternate personalities, all agree that I have no such problems.

Can RFID implants be far behind?Scary if its true. It might be. Powerful people are involved in sex trafficking. But I doubt if the technology exists to control people via brain implants, yet. If it did we would likely know about it.

content: When I was growing up I had a very good friend, Jeff, who was very smart, but it turned out that just like you describe, he had schizophrenia, which I think was either triggered or aggravated by drugs. After I moved away he apparently had a psychotic break. When I returned for a couple of days I called him up and not knowing what was going on suggested we spend the day in NYC since that was something we both had done a lot of previously. We did but when we got there on the subway he started acting really strangely, he was obviously seeing things that were not there! I didnt know what to do and he darted out of the subway as the doors were closing and I got separated from him. Anyway, that was the last I ever saw him, a few days later I had to leave town and some time later I heard that he had committed suicide by stepping into the path of a train.Whats strange is that his family never admitted that he had classic schizophrenia (which was probably treatable)Quote from: james_s on July 30, 2020, 06:51:19 pm

content: QuoteI would say that you have read stuff OTHER than "text books." Data sheets, App Notes, technical blogs, commercial and open source schematics, hobby magazines, QST, Ham Radio publications, source code, scholarly and practical research papers, and advertisements. Books and magazine articles (from Elektor to IEEE Transactions on XXX...)I only took a couple of "graduate" classes (the ones that were open to undergrads as well), but AFAIK, they're still very theoretical (possibly depending on which school you're talking about. You go from integral/differential calculus to tensors and discreet math. Whee!)IMO "Text books" by their very nature address mostly theory, and the stuff that doesn't change much from year-to-year (since publishing a textbook, and developing a curriculum based on a textboot are both rather lengthy propositions.)(I did notice, back ~1980, that Lancaster's CMOS cookbook appeared in the U bookstore. "oh! What class gets to use THAT!", I wondered... It was a graduate chemistry class about "designing and building lab equipment." Hmmph.)
