I have a complete prototype.
Against my wife's better judgment, I'm showing pictures of the hat.
I moved from the BasicStamp PICs to Arduino(ATMega168).
It supports both left and right clicks and drag-n-drop.
Left button= pushbutton.
Right button = piezo element.
I know the button thats in the mouth looks bulky, but I don't have a smaller piezo yet.
incase the images don't show up in the thread, here's the links:

It will be allot cleaner.
This is just the prototype.
I have a Arduino Pro Mini, which will fit under the lip thing inside the hat.
I'm also going to use conductive thread to eliminate all the messy wires; except the one that runs to the mouth.

I've thought about using something like that, but I don't really like the look of them, plus it would be "too big". It has to be comfortable with his wheel chair, and the bill wrapping around the entire head makes it hard for him with his wheel chair head rest.

I think it's cool as hell, man. Keep up the nice work.

Impressive work. 
And, yeah, drilling is probably the best way to go. Unless you happen to have a welding kit around.
The irony of man's condition is that the deepest need is to be free of the anxiety of death and annihilation; but it is life itself which awakens it, and so we must shrink from being fully alive.

Flesh tends to catch fire rather than just melt.
Well, there is only one (entertaining) way to find out, isn't there?

I watched a family of 4 burn to death in a trailer fire. A meth lab blew near my home, I was the only one home that day....
Well anyway, back to the point. There skin did catch fire, but it did melt a lot more than burn. I watched them carry out the two kids, and when they placed them in a body bag the skin stuck to fire fighter's suits.
Oh, and it wasn't entertaining. The screaming flames haunt me to this day.

You could place the person in an inert atmosphere and then try to weld it.
That applause I receive from y'all on posting this post would have gotten me drunk on power if I hadn't already been high on life. |

... Welding is done with a flame, right?
The end objective is to melt the 2 substances enough so that they fuse with each other. We could use a kind of heater.

Ignoring the fact that flesh is reasonably weak. Bone, however, can hold bolts.
Hmm, If we place the man in vacuum, we can then try to weld the cap to the bone. But you are right, drilling is a lot easier and cheap.

Okay, how about drilling bolts, then soldering the components to the bolts?
Meeting in the middle between both sides of this argument.
And the common perception on welding is with a torch, and with its own fuel source, it does not need surrounding oxygen, because it has a supply of its own.

Well, couldn't that oxygen cause the skin to burn?

Combustion, look it up.
Of course it will.

Oxygen is required, and unless I was tripping every chemistry lesson, I believe that in most combustions, Oxygen is used up, or rather, becomes part of another compound, meaning it won't be fit for another combustion.
Take this example:
2H2 + O2 = 2H2O
Can you burn water vapour?
combustion is oxidisation, all you need is something to steal some electrons from whatever you are burning. You can burn stuff in chlorine for example. I suppose hydrogen peroxide is burnt water.

True, but there isn't any chlorine running around in this equation.
All this assuming that the acetylene or whatever is used as the combustible gas is isn excess or is provided in an amount so as to use Oxygen completely
2C2H2 + 5O2 -----> 4CO2 + 2H2O
That is for every 5 moles of O2 or 80 gms of it, 2 moles of C2H2 or 26 gms of C2H2 are provided.
But then, is this assumption correct?

I'll be honest with you guys I haven't read the begining of this thread? why exactly does it need to be in precise stoichiometry?
Anyways from personal experience they usually supply the oxygen otherwise it's too hard to make it burn hot enough to do proper work.]
goluhaque wrote:
5 moles of O2 or 80 gms
This stands out as wrong. oxygen is atmoic number 8. but mass number 16 usually. so o2 =32. 5 moles gives 160g? I'm guessing you need to check the rest of the work too.

Oxygen in of it's self wont cause you to burn or even breathed in have ANY effects at all at sea temp/pressure blood can't take on extra oxygen (even at 100% thats why in movies you see blood saturation is at almost 100% anyways) so people getting high off oxygen is bs (in normal conditions).
What is interesting is! people with copd end up with messed up breathing regulation give them 100% oxygen and they stop breathing and actually suffocate
The fuel on the other hand could cause damage(maybe)... however the gas around the flame is so hot that I suspect whats left other would combust in air like when you turn the oxygen supply too low on a bunsun burner.

To add, and maybe help explain better:
Fire dose not burn anyone or anything, the heat that fire produces does. I'm sure that most of you know that though.
And I like how this post went from a project for the handicapped/disabled to a chemistry lesson lol. I took Chem. 3 years, fun but not my best class. I was passed with a B, and I had 5 exams out and I can't tell you how many times I never turned in my homework.

LOL sorry, weight of 1 O2 mol should be 32g and the weight of 5
moles 160g. My bad
The rest of the calculation is correct. Also, O2 alone won't cause the skin to burn, the skin when heated along with O2, that will burn.
Anyway, the guy is tortured enough, let's leave it.
