LVD

This chair is designed to enable deaf people to enjoy music. It can do this by using the speakers I modified in to transucers. This way deaf people can hear with their tactile organs instead of their ears.
People who aren't deaf can experience the music through the symbioses of both senses

Step 1 Welding the frame

Step one is to weld the frame that will hold the spine, seat and armsrests

are those... waterballons in bags?

[MCzone]

you should make this a product for the average store

My wife, once a passionate classical music lover and Sonny Terry-Brownie McGhee fan, slowly lost her hearing... 95-110 dB gone, over several years... and she has been despondent about the loss. I am going to build this, my first big project, to give her back some of the music. I have no idea how to vote or anything similar, but be assured, there is a personal and compelling fan of your work out here, in Netland. Thank you.

have you finished it, and how much did it cost
I thought it may be good for kids with parents who cant stand loud music

Great project and very nice craftsmanship. I've only seen wooden steam boxes. Would it be possible to get more information on the pipe boiler?

[bonnemichael]

it's actually a really straight forward design, it is a long pipe, about 3.5m long in thick steel wich has a hole for a manometer in it, wich I would really recommend to put in, and then the second part is the outlet, wich is a boll-tap (If you call it that way), a larger kind of on-off tap. Originally I tried putting the two together with ski bindings, but I wanted to be sure so I used screws (becouse it goes up to 10 x atmospheric pressure) normally you should put a seal in between the tap and the boiler itself, wich I originally did, but it can't stand opening and closing that well; it has about a 30 open-close cycle life span. it's not that expensive (about 5 dollar) but ity's cheaper to do it with modeling foam cardboard and it works just as good (Kappa and Bristol kind) It takes about an hour and a half from inserting the wood to full fibre saturation(ready wood) of course all depending on the kind/thickness of your wood and the temperature of the fire. To see the boiler in action, I added a video I made about a steamer and the boiler

I dunno if this would work, but when I worked in a pipeshop cleaning and pressure testing drilling pipes. They were often tested to very high pressures, and the pipes themselves are fairly wide, thus allowing more room for more wood. One length of pipe could give you several of these wood steamers. ~adamvan2000

Many thanks for the response. I've been interested in steam bending for a few years. I was thinking of building a wooden steam box. I like your version much better. It will be one of my next projects. May have to wait for cold weather though.

That was the video I featured in my article a few weeks ago! Awesome! :D

[JuxtaposedIToldYouSo]

Awesome project....SCIENCE!!!

[axydlbaaxr]

I can't figure out how to vote!!! This is marvelous.

[bryandhispup]

can you add more detail about the speakers and what not. I am totally confused as to how you did that... What are the multi colored overgrown jelly beans you put in the arm rest? and is this the finished design or are you going to upholster it?

[bonnemichael]

The speakers are made into transducers; The key here is that you need to cut away the element of the speaker that creates sound, wich is the cone. then you are left with the frame, the cilinder with the electromagnet wich is attached to the folded paper wich keeps in in position inside the permanent magnet. I had some trouble finding the best concept for this, but I found that regular speakers are the best base to begin with. just cut away the cone keeping the folded thick paper underneath, glue a piece of wood with a screw (I used an M3) in the middle over the cone witch has the copper windings (the electromagnet) with 2-component glue (epoxy resin) and attach that to what you want to vibrate. I added a .mov fragment of on of the transducers I made (before cutting up speakers) wich may help to understand the concept. It is basically a copper wire wound around a screw suspended in a curved wooden frame; the ends are connected to the amplifier output and in the video I am throwing some sinus sweeps at it. Of course the strongest movement is created by the lowest frequencies (in this sweep to about 15Hz) The difficulty in the transducer is to obtain a sensory reaction (feelable movement) at the higher frequencies (In my work on the LVD I was able to reach 1000Hz) The multicolored jellybeans are condoms (extra strong type), their colorcode is based on the LED VU meters, so that the sound can be visualised aswell. I used these becouse they have a very comfortable feel to them when lower frequencies (1-350hz) let them vibrate. to get rid of the latex feeling and to increese their strength I 'coated' them with white nylon stockings. This is the finished project; I am a fan of honest material use and I like to show how it is made up; the function creates the form. However this is prototype number two...

Looks like something taken straight out of the SAW movies. :P Anyways! Amazing add!

[Skyfinity]

OH MY GOSH! YOU ARE bonnemichael, the Wood steaming and Tubench guy! I knew it as soon as I saw your wood steaming apparatus! I wrote an entire featured article about your projects on this site, and we all said you would make a great addition to the instructables community! Low and behold, here you are! I'm so glad! The link is here, and It would be AWESOME if you could comment and tell us a bit about the process it took to make these projects!

[bonnemichael]

Well hello Skyfinity, many thanks for linking the video's here! Thanks to people like you motivation never runs dry. The tubench video is also the work of Christoph Dietrich and we will be explaining lots more of it shortely.

[rimar2000]

Very good work. Can a deaf enjoy music with this device? What does LVB?

[bonnemichael]

rimar, I have had some great experiences testing it with deaf people, I had a lady sit in the chair who was born deaf and I made a video, of all kinds of everyday things, like the sound of the shower, a cat purring, the microwave etc.., and she was very supprised that she could 'hear' all these things. Of course she couldn't recognize the 'sounds' at first without the video becouse she never heard them before.

[rimar2000]

¡Fascinating! Your work is of humankind interest, it deserves state subsidies or sponsorship from companies or organizations for the public good. But as things stands in the world, perhaps it would be more economically advantageous for you to manufacture weapons of mass destruction.

Okay randofo, The way I see it, the person feels the vibrations of the music instead of hearing it. Put your hand on your stereo or computer speakers( the box, not the cone.) when they are playing music or something. You may have to turn them up, but you should feel them vibrating. Also the lower the pitch of the sound, the stronger the vibrations are. Hope this helps.

[bonnemichael]

You're exactely right Rapidmustang, Thank you for helping explain this further

[hg341]

look scary...

[RapidMustang]

Oh yeah, very nice ible. bonnemichael, you put a lot of work into this. I would like to see more of the theory behind this though, might help people understand what you are doing more easily, great work nonetheless.

[randofo]

How exactly does this work? I mean, how is this translating audio into a tactile experience?

[rockyt]

so completely awesome!!!
