Vibrating Platform

Hey everyone I am new to this site and I am just wondering if someone could build a "TheraPlate." It is a vibrating platform for horses that helps with bone density, blood circulation, inflammation, etc. However, they are around 5000$. This may not be possible to make but I wanted to check on here and see if anyone knew how to make one! is the website. You can check it out and see what it would take to build it. My email is if someone thinks they may can/know how to do it. Thanks!

Phone vibrations?

I was looking to start a new project, and I need some help. Does anyone know anything about tiny electronic vibrators, such as the ones found in phones? What are they called? Where can I get some? I try searching for info on google and stuff, but, searching up vibrators just doesn't really give me what I'm trying to find... if ya know what I mean, its just all the wrong kind of information. Thanks in advance for any help

Vibration comparison

I'm trying to compare two wildly different measurements, but I don't know enough about the physics of sound to even know what information I'm missing. I don't need exact numbers: some upper and lower limits would be fine, and perhaps even "back of the envelope" calculations in case the required information can't be found. I'd appreciate some advice on the formulas I need and what measurements am I still missing.  Object A is producing a sound whose intensity measures 25 dB at a distance of 1 meter.  This sound is, roughly speaking, a band-limited sawtooth wave with a fundamental frequency of about 35 Hz.  Object B is being driven up and down a distance of about 0.5 mm with an acceleration of 0.3 times that of gravity. The sound doing this is a sine wave with a frequency of 35 Hz. I'd like to compare the peak accelerations experienced by the two objects.

Advice needed on vibrating motors.? Answered

For a quirky present for a friend I am making a sink plunger seat like this one . Instead of just a saddle I plan to make the seat bigger and in the design of something vaguely saddle/potty-shaped (a veebeam if you are interested, as he worked on them). Anyway for amusement rather than kinky reasons(!) I thought it would be cool to make it vibrate with a remote control. And as I know nothing about vibrating things, my question is does anyone know what I should be searching for? Brand names would be great. It doesn't have to be strong but it needs to be felt through a thick pad of stiff padding/foam and preferably with a separate remote control. Also, is there anything I need to be worried about or such like? Sorry for such a rooky question but I've spent two hours on the internet and all I kind find is how to convert vibrating chairs into XBox chairs and things that are not safe for work(!) Thank you for any help Poppy

Vibrating alarm clock help

 Hey guys,  I'm a soon-to-be college freshman and a very heavy sleeper. I contacted my soon-to-be roommate, and it turns out he's a very light sleeper and is frightened by waking up to loud noises. Of course, coming from a house where I used a phone hooked to a guitar amplifier as an alarm clock, I figured I'd have to change my waking habits. I heard from my father about an alarm clock system that utilizes pillow-mounted vibrators, but that costs waaaay too much, and I'm already going to have to balance a job or two just to get by paying tuition. Besides, I don't like buying things I can build at home. So here's my situation: I have a five-volt vibrating massager that plugs into USB ports that I wanna use as a pillow-mounted vibrator in college, so I don't wake my roomie up with a fright. My phone has a 3.5mm plug that I use to connect it to the guitar amplifier. My question is: How can I build an amplifying circuit that'll power the vibrating motor enough to work with the signal from the phone (or any alarm clock signal, for that matter)? I need 5 volts to power the motor. That much I know. I haven't measured the signal from the phone, since I haven't access to a volt-meter, at the time. HELP ME PLEASE!! Thanks.

Stepper motor vibration/lockup with driver? Answered

I am trying to get a stepper motor to turn using a StepStick driver from Botronicz. I have gotten the driver to work once before, but now it has decided not to work. I have wired my stepper motor (Model STP-42D3018) according to any specs I can find online in a bipolar connection, but when I fire it up the stepper only sits there and vibrates. Or misses steps (depending on voltage). A few other times I had it also where it would step one direction for I think a single step and then step back the other direction. It is really bothering me because I have tried multiple other wiring combinations and have not gotten any of those to work. My current setup is exactly like this (I have checked numerous times). I have also tried changing the vmot supply voltage and current limit, as well as the current limiter pot on the board itself. If anyone can help it would be greatly appreciated! Sincerely,  A907

Turn a Massage (vibrating) chair to work with Xbox 360

I had an idea although IDK how to implement it. I have a Vibrating massage chair (its just like a average recliner with some vibrators in it) I had lost the wall wort power adapter for this in a move a couple years ago and recently i had an idea while looking for gaming chairs and i thought to myself this would be more comfortable than something i could afford being a $500+ chair already i think I might try to fix it and in the process make it a gaming chair. I just dont know how........ So basically this chair uses a 12v 600MaH/.6v Power adapter (which i lost and when i was going to replace it thought i might me able to do more with this than just make it work again. So once it is plugged in it has a corded remote that has a back and seat vibration control's of off high and low. now i am not thinking of making the vibrations respond with intensity but just vibrate in general in conjunction with the system. I would say I have a Intermediate knowledge about soldering modding etc. Although I have no IDEA how to do this. I think it would somehow require a special Controller connected to the chairs power. As all i would want is the chair to vibrate when the controller does. The back oof the chair has a velcro flap that i an access the innerds of the chairs mecanism (i suppose for fixing it if it broke) So the only thing is how to hook up the controller in a way its not obtrusive to controlling it and simply how to do it. I know this may be a hard question to ask about without someone seeing the chair but is it possible??? How do gaming chairs achieve this effect ????? I would like it to be connected to the controller somehow and not the xbox as the cord is undesirable. So basically all I need to do is make some sort of circuit that is connected to the xbox controller that turns the chair on when it turns on. thats basically it. so first of all is it possible and if so any pointers??? I think it would also make a nice instruct-able after I find out how to do it. I assume it would require some soldering and at MOST and Arduino but I hope not as i do not have much experience with them. although if it does maybe someone can help me and all the Arduino Programing would all be credited to whoever helps me with the code. So yeah I would like to make this work I really think it would be cool as i already have a sound system that is good enough for sound (i can easily wire some extra speakers to be mounted behind the chair and once i get the vibration i would basically have a nice lay-z-boy gaming chair IDK. I have no xbox controller modding exp ( i never really wanted to or had the need) so it would be a learning experience for me although if it could be done with a USB connection to the Xbox that would be ok for now ( i would run it under the rug but its not the optimal result i want) In all since this chair already has the vibration mecanism i would think it would be possible and hopefully not that difficult to do. (at least i hope so) If this interests anyone I would GREATLY appreciate your help. and i will certanly tag anyone who helps me with this when i finish and make an instruct-able. So in all thank all of you who reply to this post and I hope i posted this in the correct forum as i never have asked for help on this site. THANK YOU ALL IN ADVANCE
