There are piezo based linear and rotational actuators but they are limited to certain surfaces and they tend to resonate at the high end of the audible frequencies making them not practical for many applications. I think applied science has a video on them or at least they show up in one of his videos.

movements based on vibrations suck balls. This little hack is not how good engineering is supposed to work.

🔴 Why Islam not other religion 1-islam gives logical and simple idea for God - he is A perfect God - he is not a man nor a son of man nor an Idol or a trinity nor limited nor created - he is totally unique and to him belongs all the good qualities 2-Islam accepts all messengers of God -- about 124 0000 and in Islam, we love all the prophet of God and we can’t deny any of them - while in other religions such as Judaism for example - they reject Jesus and Mohammed -- and in Christianity they reject Muhammad ... but in Islam, we accept all . 3-in Islam, there is no mediator between you and God -- you can pray to God directly - there is no need for someone in between... 4- Islam is the Only religion that is Not named after a person or a tribe or a group, its name means submission to the One True God, if anyone anywhere at any time lived the life of submission to the true God alone , then he is a Muslim. 5- In Islam (worship) is not about mere rituals. it's a comprehensive term that includes any deed that pleases God. All good deeds are types of worship, smiling, being sincere at work, saying a nice word, and even treating one's spouse gently, all this is greatly rewarded by God. And in the opposite any deed that doesn't please God is a sin; talking bad about people is a sin, cheating, lying, hurting innocent people, harming the environment. 6-in Islam God is always forgiving - if you always repent (before death ) he will just accept you no matter how great sins you did >he forgive us out of his own grace - there is no price to be paid in order for him to forgive > so it's not like Christianity which says that God can't forgive except by blood of Jesus .. 7-Islam is a way of life - it organises each aspect in your life.. it has solutions and divine guidelines to problems in your life . 8--the sources of Islam also was collected and saved is also amazing -- it never happen to any book in history --- it's through the uncut chain of known narrators which date to prophet time ... besides the millions who memorised it from cover to cover since that time up till today - besides being documented in front of the prophet by known companions! 9-Islam prohibits blind following without knowledge and it invite us to use our brains to know truth, it is based on evidence and logic. The rational mind is the basis for religious accountability and responsibility. 10-the moral system of Islam is v high and perfect and thus the countries that apply Islamic laws in a proper way -- they have less moral crimes. 11-You won't lose Jesus if you accept Islam, but you will just correct your belief in him , In Islam, Jesus stands a good position in Islam as one of the messengers of God together with other messengers.. they were all special and they were all humans like us-- none of them must be worshiped -- we only worship God who sent them . we believe that Jesus was a noble Messenger of God but not divine,,,, we love Jesus and obey his true teachings and pray like him , fast like him , and a person won't lose Jesus if he accepts Islam -- but you will just correct his belief about him 12- Paradise in Islam is a real physical life for both Body and soul, you will go there , eating drinking marrying and meeting with prophets and having wonderful eternally unlike in other religions which they think its only spiritual life. 👉IN ISLAM THERE IS A PURE & CLEAR CONCEPTS OF GOD 🍃🍃🍃🍃🍃🍃🍃🍃 God is One and Unique: God has no partners, no equals and no rivals. God has no father, mother, sons, daughters or wives. God alone is worthy of all worship. God is the All-Powerful: God has full authority and power over all things. Obedience to God does not increase His Power, nor does disobedience decrease His power. God is the Most High: There is nothing above or comparable to God. The attributes of God do not resemble that of His creation. No part of God is present in anyone or anything. God is Perfect: God does not have any human limitations, such as resting on the seventh day after He created the universe. ..

@@ahmdabdallah5811 ok wtf

@@blackferrets820 just report it as spam or something like that

Thank you so much 😊

Yes that can be done by using multiple piezo actuators 🙂

Also, as I noted in my own comment, the track pad haptics are also what play the little audio sound bites on power up, shut down, etc.

Grazzi 🙂

I don't believe reversing the signal would work.

@@Brain_pocketer a few weeks ago I took a piezo buzzer from an old smoke detector and plugged it into my computer's mic input. It actually does work, but with the caveat that it doesn't really pick up vibrations from the air. Scratching the buzzer yields high quality scratching noises, and if I hold it against my throat or press my lips to it then it can pick up my voice, albeit kind of quiet and muffled. If I had a large, thin, stiff sheet that could pick up vibrations from the air well, then I'm sure it would work pretty well as a crappy mic, but it does technically work on its own. Piezoelectric pickups just like that are used in instruments all the time.

Haptic signals can go up to +-100V while the touch would be 500mV - 5Vmax.. With the potential the signal for the touch goes in the mV range but keeps it safe at haptic actuation

I agree after doing this project I think using some adhesive or double sided tape will work better than screwing the thing

@@CarlBugeja: Another thing that is important to consider is that the low cost piezo buzzers typically do not operate in a simple compression/expansion mode, they actually curl, or change from flat to hemispherical. For better push button sensitivity, it would be better to support the piezo disk at the edges and push down only in the center. I once tried to use the low cost piezo to keep a large mechanical pendulum swinging but it was a significant challenge to utilize the unusual mechanical deformation properties of the piezo to feed the mechanical pendulum. Thanks for the interesting videos!

Thanks!! This project has been on my buckit list for so long 🙂 as an engineer I'm fascinated by piezos!

@@CarlBugeja No wonder you took your time to explain it all. I love your stuff.

It can 🙂 but its designed to be used at a specific resonant frequency (that's why it's a buzzer)

@@CarlBugeja ohh i see

Agreed. Also using a jetson for the visual sensing part of this might be a good idea

@@michaelarview post your work, I'd love to follow along

@@jonnupe1645 I have very little work that actually gets done. Im mostly full of ideas and plans without the action though id love to discuss any ideas with you for fun.

@@michaelarview lol I'm in the same boat actually, so ya that sounds awesome

@@jonnupe1645 ight ight you have discord by chance?

I think in theory it would work but to connect them electrically it would be a little hard to do.. They have to be compressed so wires cannot be used between plates

@@CarlBugeja You don't need wires between the plates. Just stack them, like knop cell batteries. Maybe a round piece of copper foil between them would increase the reliabillity, but wires are not necessary.

That can be done 🙂 but for a haptic Button the two functions are not used at the same time so one piezo can be shared as seen in the video

That wouldn't be anything new Also it would require static displacement

@@CzornyLisek anything new? Gloves with that technologu and nfc can "read" what writed on the street or navigation, that haptic on the belt can "show" in what direction u must go, need 5g or good Lidar.

They're more like to to just run with the idea and claim they invented it.

Yes ⚡ electroboom style haha

@@CarlBugeja You are a mad man😂

It's very low power so a tiny shock won't hurt

Well I hope you wont get addicted to it like electroboom....
