Can anyone build me a wrist countdown timer? PM for details

I need some help. I need ideas on how I would make this. Basically I want to make a wrist-mounted pistol (fake). If you've seen Assassins creed before, they use a hidden blade that is spring loaded. Also this was in Sherlock Holmes (professor). What I want is is to sit on my wrist and when I push a button behind the pistol, it ejects it forward so i can grab it. I apologize if I'm not being clear.

I'm developing a holder for my Droid smart phone, that would allow me to use it like a wrist computer, while protecting the phone at the same time. Would anyone be interested in an instructable? I could make it so that the plans would be adaptable to most any touchscreen smart phone (I can't promise it would work for every phone, but I'll try to make the plans as universally adaptable as I can.)

Their basically is not a thing like that out their. I want to build a wristwatch that can shock me at a resettable time. I will keep it on when I sleep so It has skin contact. How do I do this? Please help me because I wont wakeup from anything else tryed everything and I hope this will work.
Found this at Boing BoingOver on Boing Boing Gadgets, our John spotted this vintage wrist-mounted scrolling map from 1927, an antediluvian wrist-mounted GPS: At first glance, this 1927 map watch is pretty nifty: an antediluvian GPS, don't you know. It was called the Plus Four Wristlet Route Indicator, a name so clunky, unmemorable and artless that it even sounds like the name of a modern GPS device. The idea was simple: the Wooster-esque motorist would putter around England, scrolling a tiny paper map loaded in his wrist as he went with two black knobs. If you took a turn, you simple slid out one map and inserted another one and continued on your way. What ho! Ingenious! Except a complete road map only cost a few pence back in 1927, where as this device would have set you back around 5 quid. And just like modern GPS map providers, the real business model was in selling you additional maps. Which leaves the design. I quite like it: it's cheap, but whimsical and adventurous, like something you might strap on your wrist to traverse Oz. LinkLooks pretty cool and steampunkish. I would love to have one.

I've always had an intense fascination for lucid dreaming. Finding ways to communicate or control outside devices based off the slight body movements that are possible despite the natural paralysis during sleep is a topic of great interest to me. I have several LDs (lucid dreams) each night and through much experimentation have found that with a bit of concentration, I could move my fingers enough to trigger very sensitive buttons (if placed perfectly before falling asleep) or to grip myself (if my hand is placed say, near my neck before intentionally entering a dream from waking) such that the sensation of my fingers reaching my neck would wake me. These experiments were proof enough that if I perhaps had some sort of glove or wrist mounted piezo sensors that are able to detect the individual tendon/finger movements with high enough sensitivity, combined with software that can parse patterns and reliably filter out minor unintentional simultaneous movements for the fingers that are prone to movement when others nearby are moved, it would be possible to establish one way communication with outside devices, the Internet, etc. Input could be in the form of different patterns or even text (tap code, morse code, or through a hybrid allowing use of each digit of the hands) or musical notes (each finger representing a note of a scale with a finger or two used to change octave or to toggle sustain.) As a musician who "writes" his best music within his dreams, this could be quite handy for getting melodies down before they vanish from memory on waking. For example, to activate input, you could perform a simple pattern that is unlikely to be triggered unintentionally. It could be as easy as left thumb flex, right thumb flex repeated in that order several times. From this point, you could use another pattern to choose to trigger an alarm (sound, vibration or electrical shock), or to initiate musical or text recording. There are many different uses that could be explored, and it might even be possible that 2 way communication could be established if a reliable method of transmitting to the dreamer without waking them could be created. This is however beyond the scope of my intentions. I have suffered from sleep paralysis on a nightly basis for over a decade now which can be extremely frightening and last up to several minutes, and during this time I am able to move my fingers as well as shake my head back and forth (which I need to do to break out otherwise the paralysis will persist until I'm pulled into a nightmare.) My solution to these terrifying experiences was wearing a heart rate monitor with an alarm that goes off past a certain BPM, which only happens when I am frightened. Now that I am so used to these experiences, my heart rate does not increase enough that I can reliably use it as a trigger without also waking myself out of exciting dreams that I'd rather not have prematurely terminated. I am fairly confident that a device such as this could help with breaking out of my paralysis at will and PERHAPS even be sold commercially to other sufferers of this condition, however niche the market. Giving me control over my sleep paralysis alone would be a highly satisfactory result with significant quality of life improvements and be worth the effort of building this. Waking up partners in bed with my head thrashing is less than ideal! As an avid software programmer, I do not think that the code involved would be terribly difficult. However, I have very little electrical knowledge and building this without existing plans would be tough and time consuming. It would be enough to have a pressure/flex voltage for each digit transmitted to a Raspberry Pi or via Bluetooth to a computer and the rest could be done through software. My questions are.. Does a commercial device exist that would be suitable for my purposes and not be terribly expensive? Perhaps a glove? Is a wrist strap with piezo sensors over each tendon that control the fingers a realistic possibility to achieve my goals? I do not need to know the position of the fingers or whether it is pushing against something. Just that movement is being attempted. Do existing plans exist to create a similar device? Thank you!

I have a hat that I attached a working battery-operated clock to. I would like to know if someone could create something for my wrist to cause the clock on my head to change. Ideally it was cause the hands to spin rapidly clockwise, counter clockwise, and return to normal function. Extra bonus for being able to set the right time from wrist, but not super important if it's crazy more work. I was thinking the wrist strap would have a Vortex Manipulator sort of look to it. The idea is that the hat and wrist item work together to be a time travel device. It's for a steampunk outfit. Any one think this is possible? Thanks! [EDIT: According to Radioshack, they believe I would need a special clock motor to accomplish this. Any idea of such a thing exists?]

Alright, fellow Instructablers, I need help. I'm not usually a forum-poster; I like lurking. But I'm getting a little desperate. About a month ago, I was in a bit of a car accident. The airbags went off as I was trying to turn away from the telephone pole, and so my right wrist was in front of the steering wheel when the bags went off. This means that my right wrist (yes, I'm right handed) is still recovering, with the current diagnosis of "soft tissue injury with a sprain on top." I'm going to see a hand specialist, but in the mean time, it's quite the wrist brace. Though I can use my fingers, I can't do much without pain/stiffness/etc. So here's the problem that I'm posing to you: what can I make? I'm going stir-crazy. I knit, I woodwork, I play with wire and jewelry making, I draw, I take things apart... I'm willing to learn any new medium and play with any new toys. But I can't use my wrist. So, what adaptive techniques or simple projects or mediums do you suggest until I'm back to full powers? TL;DR: Can't use my wrist, but want to keep making things. Ideas?

They'd mostly be just for show, but having at least some kind of decorative functionality (i.e. lights, sounds, lenses, etc.) would be nice. All opinions and ideas are very much appreciated!

I am feeling a contiuous stress in the wrist area of my left hand. and also some numbness there in the last two fingers, which i think is due to continued keyboard and mouse use.

Hi all, I have been struggling lately with two problems: #1: tendinitis of my lower right arm and wrist #2: arthritis of the right elbow. The doc believes both are aggravated by overuse of the mouse (actually resting my hand on it an entire work shift, plus the time I spend on line at home). The first thing I must do, of course, is unlearn the behavior and remove my hand when I am not actually USING the mouse. This hasn't been very successful so far. Does anyone have any further suggestion on how to "rest" the arm and still be able to go to work and work a bit at home? Anything serious will be considered.

My idea is to attach a contact microphone to the wrist to listen to finger-taps and determine which fingers produce the taps. Assumptions: - The tap sound propagates along the bones like in tubes, - Each finger produces a characteristic sound signal. - Pattern recognition of sound signals identifies the sound and the finger that produces it.
