Electric muscle stimulator

As part of my therapy for a painful shoulder dislocation I receive electrical muscle stimulation on my shoulder. I wonder if someone knows how to safely build a home made one.

Need muscle suit.

So here's the thing. I'm building a green goblin costume(humberto ramos kind) and I need to make my self look a little bigger.  I don't need to see any muscles just bigger. I've considered  using bubble wrap but I'm afraid I might die from Hyperthermia, plus if I sit down it would sound ridiculous. So the next obvious choice would be to use upholstery foam, but I've never worked with it before. I've thought about using plain old newspaper and and strap it down with duct tape, but I think that might be noisy when I walk. Check the pictures to see what I mean. One picture is from a comic book and the other one is a costume made by jacemoore on deviant art.

Something quite odd happened...

Ok so I had some trouble sleeping the other night, in fact I had an awful lot of trouble and ended up not sleeping for for near enough 48 hours, not unusual for me considering all the stuff happening but read on... I had sprained or stretched almost every muscle in my upper body before this happened and it had been hurting like hoohah just to move, I sit up reading etc for several hours and then descend to start the monrings activities and I noticed that all of a sudden everything has healed, even the massive pain in my shoulder from a fight during which my arm got twisted to almost dislocation... Any theories on why this might have happened, the only thing I can think of is the fact that by being awake and not moving too much it was like sleep as far as healing goes but my metabolism was higher since I wasn't sleeping... Does that sound plausible?

How can I turn pnuematic muscles into hydraulic muscles?

Hi everyone, thanks for taking the time to read this Recently I've become interested in these pnuematic muscles: https://www.instructables.com/id/How-to-make-air-muscles!/ I wondered if it would be possible, and what sort of pump I'd have to use. I wanted to make the pump fill the muscles as fast as they can, and I wanted it to be fairly portable (running off 12 volts or something).  Thanks for your answers!

rifle exercises

Does anyone know of some good exercises for helping hold rifle steady? by exercises I mean which muscles to work on and how, as well as some shooting exercises. But, because I am 14 and live in Australia, I only have access to a gun at the range, which I go to twice a month, so obviously I can't do shooting exercises at home. thanks, THE MAD MAN

Tesla Coil Safety?

My high school recently had an engineering fair, and my friend had built a tesla coil. Its has multiple spark gaps, an RF filter (I think thats what its called), a 120 to 20000v transformer, and toroid top-load, if any of that matters. We/I would entertain ourselves by standing away from the coil and holding a fluorescent tube (by the glass with bare hands, not by the contacts) near the top-load and watching it light up. Even though I was well away from the coil, my forearm muscles would twitch, especially it the coil spark hit the contact on the other side of the tube. Then if anybody touched me, both of us would feel a shock and the same slight twitching (the same kind of twitching you feel from those electric muscle stimulators with the pads you put on sore muscles). We even set up a chain of about 5 people holding hands, and all of us would feel a shock, even though only the first person in the line (aka me)  was holding the fluorescent tube near the coil, with my hand on glass, no where within range of the streamers coming from the top-load. Now for my question: is this dangerous? (I know its non-lethal, im talking about my nerves) And what exactly was happening? because it was not an incredibly large coil, and i know that the field of a coil is much larger than the actual streamers. I also read somewhere that insulators dont work the same at incredibly high voltages. I think what I was feeling was the skin effect, and the charge came from the excited electrons in the tube. If my ideas are correct, then wouldn't me holding the tube be just the same as if i had just put my hand near the top-load and let the streamers hit me?

I want to use nerve impulses from muscles as a data input. Answered

I need to find out how to get a nerve impulse isolated and use it as an input.  I beleive a myoelectric electrode with a window comparator may work.  Instead of using an op amp to boost the impluse to run a motor, I want to use the impulse as a data entry signal.  I know that prosthesis use this system and I want to adapt it for signal input.  My goal is to use several nerve impulse sources to be used as a data input device to allow those with CP, or amputations to more easily communicate.  I am trying to bring a very old idea I had 20+ years ago to reality.  I have joined an open source prothesis forum as well as an Arduino forum.  I want to use the Arduino to "translate" the input combinations into a data form that a computer, PDA, or smart phone could use.  I want to keep this open source as I am not interested in a commercial venture. There are basically two steps.  The first is to use an Arduino to convert 5 touch pad inputs into 120 "characters" that are identified with various platforms.  5 inputs will generate 120 combinations (5x4x3x2x1) and that will give me a simple keyboard input.  I have to work up a timing method so that the Arduino will identify when buttons are pushed individually vs at the same time.  Next to have the Arduino generate a digital output that is compatable with a keyboard to keep the application flexible. The next step will be to identify intended muscle nerve signals from background nerve signals and 'filter" out unintentional signals.  Next, the buttons with the myoelectric inputs as the input to the Arduino. My goal is to have a myoelectric (or similar) input device that does not need muscle movement to generate data that is recognized by (practically) all devices.  It could be used for text generation, then voice synthesis, as well as a data signal for motors on the prosthesis to give better control.  Touch screen devices are proving to be a big challenge for those with prosthesis.

Any suggestions on what else we could do or more idealy how to shrink these systems?

How can I control hydraulic pistons using myoelectric (muscle signal) sensors ?

Hello, this is my first post. I've run into a problem. I've designed an exoskeletal armor system, yet don't know how to control it. I have an approximate idea; using myoelectric sensors on the major muscles of the arms, torso, and legs, it will track and replicate muscle movement patterns through hydraulic pistons in the suit. Problem being; I don't know how to activate the pistons using this method. I don't even know if you can attach the pistons to a micro controller the sensors are hooked up to. Any information that may help is appreciated. I am in no way a professional after all, and this is my most ambitious design yet. Certainly to be the most complicated, expensive, and tasking build I've done too. I will upload the designs whenever possible, as I have no scanner at this time.

My arms wont/haven't buff up, and eating problems

               So I have been working out since 3rd week of December last year and maintained regular workouts and exercises weekly , I've done dozens of reps of push-ups, Pull-ups, barbell curls and other barbell exercise, some face pull, squats, Pumpings, curl-ups and couple of abdominal Muscle Exercise. I know im a bit too young for a 15 year old, but I've been skinny and thin since grade school, so i've decided to get on the muscular exercises.                                I started it last year's summer but i wasn't able to do it regularly and mostly busy on my studies and some school activities. I noticed my biceps, shoulder muscles, abdominal muscle (it seems the upper muscle is in pretty good shape, the ones below the ribs except the lower ones), my calf muscle, thighs seemed to improved but it seems they just getting harder or something like that but it is not growing bigger and I still look Skinny. I know good body shape take months and years of hard work but it just seems like nothing is happening to me.                 Also, I think i got a problem on my eating habit, I dont always feel full or satisfied, that when I eat Im still hungry but i can't take any more food. And I also noticed I mostly cant swallow my food even if it's grinned in my mouth, that I need to drink any beverages to swallow it, the problem when i drink to swallow my food is that i always feel full because of the water, but even if i eat without drinking much water, I still cant finish my food.               Im still skinny as hell

Do I have a Tetnus Infection? Read the Description

Today while using an exacto knife to cut some excess material on a shelf, I used too much force and the knife slid off and poked my palm. About an inch below my thumb. Now the exacto knife I was using wasn't in particulary good shape, some rust, and white out on the tip. This was an old tool I was using for not so clean projects. Well I managed to poke myself and I was wondering if I have a Tetnus Infection. The symtoms are muscle spasms, stiffness, and lockjaw. I read symtoms never occur on the first day, but now it's been 2 hours since I was cut and my right lower bach is starting to ache, maybe I'm just paranoid and it's because of my poor posture when I sit and I'm focusing on it. I washed the wound with soap and water twice, put a band aid on it, took it off when I read it needed oxygen to kill the germs, now I'm typing this. The last time I hade my dTap was probly maybe 6-7 years, or 1-2 years I cannot remember. I can't go the doctors because of reason I can't explain right now. If it gets urgent I'll call a paramedics or something. Should I be worried? Should I get to the doctors to get a booster? Should I go cry in the corner while the effects of Tetnus slowly overwhelm me to the point where the muscle spasms reach my back and I start to spas out unitl I die?
