There's no way that little bit of force hammered into a piezo assembly would create enough power to move that large projectile hard enough to pierce that can. Also the board appears to be unsecured, yet there's not enough recoil to equal the force put into the projectile nor the force exerted by the hammer. Movie magic.
so a piezoelectric can produce around 13v and technically speaking you need at least 10v to make a coil gun work. so yes this can produce enough force to pierce the can because it doesnt take much at all. the projectile looks big, but if you look closer its just metal wrapped around a plastic straw so it doesn't need a lot of initial force to get going... so actually the physics here makes perfect sense. those cans arnt that tuff to puncture and the projectile didnt even go through it, just the tip. i think your just overestimating the cans resistance to being punctured
@@SaltyRad voltage is not a big deal. A piezoelectric can generate way more than 10 or 13V under the right conditions. What it lacks tho is the power to accelerate that projectile
@@Grazey for a Coilgun you need High Voltage aswell High Current -> Large amounts of energy. My Coilgun has 312J Electric energy which accelerates a projectile of 10g to 35m/s. A coilgung is pretty inefficient as you see. Important is that you have at least 200-300v so that enough current can flow through the coil. A piezo won't even deliver 1J of energy and if you try to use a transformer you get a loss of about 32%. This is a pretty pointless idea if you don't have a HUUUUGE piezo...
Well, this kind of project reminds me of the many experiments I did as a kid. They didn’t usually work and neither did this. But I’m still proud of you as my mother was with me. Here are two successes I had as a child. 1) I got my hands on a hoard of little glass bottles. I had been experimenting with building a light bulb. So, I used the bottles with rubber caps. I made a hole and inserted fish tank tubing. With magnet wire I wound a little tiny coil. Since the wires were insulated with shellac, I inserted them into the tube and installed that cap on the bottle. I had just inserted the tube in my mouth and had sucked a very high vacuum on the bottle through the tube. As I was fumbling around with a 9-volt battery trying to connect it, my mother ninja walked into my room with my back to the doorway. Apparently, she watched me for a little while and could not understand what I was doing. Out loud she exclaimed, “DEN, what in the HELL is going on in here!?” She scared the shit out of me and I delayed in my answer because I needed to release the vacuum without a bunch of spit sucking in there. Despite my irritation, I rationally explained I was making a light bulb that I was now testing. She paused an uncomfortably long time. You see, her brothers had engaged in pot at a young age, then LSD and who knows what. Finally, she explored and asked why the tube was in my mouth and said “show me”. I had no idea if my bulb would work. If I had success my mother would trust me the rest of my life. If I failed, it would be curtains for me. I spent the next five or ten minutes pumping down the vessel with my mouth. Finally I connected the battery. It glowed very brightly and did not burn out for the five more minutes I kept it illuminated. Years later, when I did start to experiment with drugs and alcohol, I don’t think she detected it because my grades had already fallen for years. And my spare time was spent at the library during the day and either my friends or my bedroom building my next contraption. Thank God I escaped the lifestyle and became an engineer. 2) I had a previous incident when I was experimenting with steel wool. My erector kit was stored, closed in a plastic box. I inadvertently stored my steel wool and my 9v batteries in there and went to play outside. Per chance, I needed something from my attic space workshop. When I got in there, I witnessed the kit glowing red and emitting smoke. I grabbed it and ran down the long staircase and put it on the sidewalk outside. Then I spent the next hour in lectures and explaining myself. Mom was not amused. It’s a wonder. After that I switched entirely to computers and electronics.
@@seditt5146 In a state governed by the rule of law, only a court can make an accusation. The same court can punish a person for making a false accusation. But all this is valid only for those who do not hide their personal data. I'm not hiding them. So you can go to court if you're rich.
Well thats more or less just what happens when you punch a dmall hole in sheet metal like that. The metal doesnt like to deform into complex curves so it usually just tears.
I’m curious as to what your core crystal is. It could have a wide variety of applications on the small scale. Like small but high power solenoids as an example
What did you mix in those two small glasses? Can you explain? But a 1000 microF electrolytic I would have added it!!! I have to make it. It's a mix between the bullet weight and the range.
Interesting!!! But the coils how many henries do they have? I would like some technical details before venturing into construction. I like to be precise. :)
A piezo-electric generator is the exact opposite of what is needed to drive the coil. The coil needs a pulse of high current . A piezo will give you a high voltage pulse and not so much current. This piezo-electric generator, must have run on magic pixie dust.
Ever heared of U=R*I? The more voltage the more current. (i know not that easy with inductance, but still the more voltage the more current change per time interval). The problem is the time, which is too short for the piezzo.
@@neutronenstern. the Ohms law doesn't apply on inductor as it is not a linear electronic component. The piezo doesn't work like that. The more pressure you put on it, the higher is the voltage spike. The inductor in the other hand needs current. The bigger the coil in mH and above, the higher current it needs to charge itself up. That's why you see motors running on inductive magnets start with slow speed and slowly go to the peak of their RPM. That's why, he is right. The inductor needs current spikes, not voltage spikes
@@themoonwolf7438 yea true. But still u(t)=L*dI/dt. So with high voltage, you get high dI/dt. So if the voltage was high enough, and also the time interval was high enough, the current would have been high enough. So like i said, if duration of thd voltage spike would be long enough, the current would have been large enough.
This may not be fake. I am seeing people call this fake, but they are failing to see everything involved in this piezoelectric button. It's much, much more than that. The substances within the piezoelectric button are two colors for a reason. This reason, is that it is also a battery. That's correct, a near solid state (if not solid state) battery that also has piezoelectric properties. Even the plates, whether TiO3 or Sio3, ect. Nothing is going to waste, not even the pigmentation.
How do you think we could make a hank cranked continuess piezoelectric spark mate, somebody apparently made one so they could use the high voltage to create plasma.
I have two hypotheses: 1. Tribochemical reaction of two or more substrates, 2. Physical piezoelectric process. In both cases, the coloring of the elements is only intended to mask the real process for public.
Could make a interesting single stage coil gun. This config could apply a very strong pulling force for a short period. It would have a downside of being very difficult to make a multi stage system with this kind of config though. But with a very strong electro magnet and maybe a stronger striker it has a good bit of potential. Even a larger crystal could have significant effect on such a design. Also there is a pretty big benefit of being very simple with no capacitors or fancy electronics which means zero charge time. This would be something most coil guns can’t do.
Почему пацан из фильма один дома не применил это изобретения для борьбы с ворами? Ведь это изобретение по эффективности похоже на все те что демонстрируются в фильме.
Пьезо элемент из эбоксидки, это почти как фокус с зеркалами что материал разделяющий цветок от газовой горелки. Если между молотком и пластинкой пьезоэлемента положить диэлектрик, то установка не работает.
Супер! Снимаю шляпу! 😁 Но, как инженер, не могу не задать ряд вопросов. Оранжевый и голубой- это лучшие цвета эпоксидки? Из моего личного опыта, например, желтый с голубым ("жовто-блакитний", я- украинец) иногда дает удивительные, неожиданные результаты! А если немного "доработать" установку и исключить пьезо и катушку, оставив только "пулю", направляющую трубу и пружину? Классическая физика утверждает, что результат должен быть еще лучше.. Но интуиция (старого инженера) мне подсказывает, что он уже не будет таким "впечатляющим"! Спасибо за хорошее настроение 😁. Вітання з Харкова 😉
How to make a good piezo. Which elements and in what ratio did you use them? I don't think it's possible. I would be happy to check, maybe your piezo is giving more energy. Good video. Lots of views. Best regards.
Look for information about hazardous chemical compounds on the darknet. Otherwise, the dissemination of such information on the Internet is punishable by law.
You can ignite alcohol with a high-voltage discharge. And dangerous chemical formulas cannot be published on the network. This is usually done on the darknet.
Piezo is German scientist. Gramaphon record pointer called stylus generating the voltage on same principle, what I called diamond point. I think he invented in 1936. We got in college studies in 1970, in physics ( modern physics)
It's fake. I was curious at first - dubious when I saw the "piezo", and then the punch was the "yeah, no." Kicker. You could, in theory, do something like this, but you would use a much thinner gauge wire. I'm also not too sure how efficient piezoelectric materials are at converting strain to any kind of power - how much of the kinetic energy striking them is available for use by a circuit as some combination of voltage and current.
@@IurisWorkshop the concept of a electromagnet is the current applied across an inductor. If there is no resistance whatsoever, then there is no voltage drop across the coil, therefore there is no current according to ohm's law. an inductor (or coil) is theoretically a short in DC. You actually did not need to insulate, and actually you could increase the magnetic strength if you use a iron tube instead of fiberglass (as this also increase magnetic flux because of the transformer theory) try it out.
I see many comments saying the power is not possible, he also said he is not giving the formula. But if you use your skeptical brains and just think If possible? Did you even consider putting piezo generating materials into Non Newtonian conductive fluids? To store way more than wafer thin examples? Probably not. If he coated the pick up plates with graphene conductive ink it would be even better!
You have the most translucent skin I have ever seen! I'm not making fun, it's really interesting. I bet the phlebotomists love you! And your video is really interesting too! ☺️
А дайка мне рецепт твоего пьезоэлектрика, а то как раз я химик и лаборатория есть, и ты не представишь я и физик и для физики тоже всё есть. И хрен с ним и так понятно что без датчика выключения реле, снаряд встрянет по середине, ну и ладно не удивил, таких много, но у меня больше вопросов по пьезоэлектрику, ведь это фантастика сделать пьезоэлектрик в кустарных условиях так и чтоб он выдавал нужное напряжение для реле, а его нужно не мало. А ну и как же без всеми любимой фальш-досточке где обычно прячут тонны аккумуляторов.
Публикация опасных хим. формул приводит к бану ресурса, а иногда и к сроку. А вообще сейчас многие работают над источниками тока. Вот на днях читал: news.mit.edu/2022/aluminum-sulfur-battery-0824 Конечно без формул. ;)
Если вы о снаряде, то он может быть изготовлен из любого магнитного материала (магнетика), например, стали. То есть, магнитом ему быть не обязательно. Снаряд намагничивается под действием магнитного поля, возникающего в соленоиде. Можно стрелять обычными гвоздями.
Exactly the gas lighter formula, here it has been enlarged in the same way so that if more current is produced, then the bigger coil produces more magnetic effect than more current
Я как увидел винты с плоским шлицом, мне прям больно стало))) Но видос прикольный. Неужели пьезоэлектрическая пара действительно способна выдать такую энергию?
It’s fake af. The coilgun itself would work but not that "piezoelectric" stuff. It could never produce that much current and it could also never crystallise properly with the added dye.
