I need a type of solenoid/servo device capable of moving a few millimeters at a fast speed. I am building a device that will tap a touchscreen for me via an electric signal (In this case, and arduino.) they need to be relatively cheap and small. I will have four of them evenly spaced over four inches (They need to be no wider than an inch, would much prefer they be less than a half inch in width. Height isn't important, and length should also be under an inch.) They also need to be fairly weak, i dont want one of them punching a hole in my tablets screen by accident. Doesn't need to be controlled by PWM, either off (Not touching) or on (Touching) will work fine. Please do leave links along with the name of the device/part.

How do you jail break the ipod touch 4th gen? (newest one). And what exactly does jailbreaking do? please answer. thanks

If anyone wants to trade i have 50 dollars worth of itune cards if anyone wants to trade add me if you do :):):):):):):):):):)

Hi, i a video in youtube that explains how to make a multitouch screen with a wii remote and i was wondering if you can make the same but with an ir webcam/video camera. [and i have a probably stupid question but how to make a 4 point calibration in windows vista...} {Sorry for the bad english but I'm portuguese}

Good day!I have a special problem and I am not even sure this is the right place where to ask for help... I have carpet in my office and by walking around I get charged like a battery (electrostatic)...Often I touch someone and I get a shock! (Also the other person, at least I am not the only one...) This is pretty strong some times and annoying most of the times so I thought maybe I can make (or maybe it exists already) a bracelet or a ring or anything with a LED or with any kind of resistance that I could wear and it could "decharge" me. I think I can figure out how to make something fancy but I am not that, lets say, skilled in electronic and I don't know what would actually do the job. Am I the only one with such problem? Does anyone have any idea?

 Hey I want to make a touch pad that if touch in a certain area will change the resistance level and hold this even after not being touched....how would I do this???

Would you guys consider a ipod touch for a droid a good deal. The ipod has a 40$ case and is a 8gb.

So my friend gave me this ipod touch with all his stuff on it but he left to go to america nd im in australia but i rly want to get his apps off onto my comp but when i sync it it sais that the following apps need authorisation. does anyone know how i can get authorisationwhen i cant access my friend?

Hello. I have a lot of threads stretched vertically. I want to detect the touch them. So that you can then play them like a guitar for example). What is the easiest way to do it (detect touch, not to make a guitar)? What kind of sensors could you recommend for that?

Could you include an Apple Touch Icon on the website? I know Instructables doesn't have an iOS app. Primary reason being that you want to focus on the website. I fully support that. I would like to add a shortcut to Instructables (my feed) on my iOS devices and I would like the bookmark to have a proper (Apple Touch) icon. Just because it looks nice and I think it would support Instructables' web app approach. Thanks.

So all the talk and youtube videos are making apples ipod touch 5 look amazing. With 5 color choices, a-5 chip, siri, better battery, better cameras, and so much more it is got to be great. So i say all that to ask when it comes out "Will you buy it".

Is there such a thing as a switch that is touch sensitive so just a tap will activate it. I want to make a lamp out of an empty glass coke bottle and i want to be able to touch the cap to activate it. Im looking for a small piece of silver metal that will match the cap so i can place it on top, OR a way to make the actual cap the switch. Thanks!

I have a cheapo 7 inch android tablet and the capacitive touch screen doesnt work well, some spost work fine but others dont what should i do? also is there anyway of connecting an arduino up with a usb adapter so a program can control it?

So I've known this for awhile and to be honest it doesn't bother me to badly but my Zip series is much more popular than my Competitor series. The first Zip has more views than my first Competitor which has been out for months, but I do realize the philosophy out with the old, in with the new so I could see the original Competitor collecting dust, after all, it doesn't even have a mag lock! Anyway the main reason I'm starting this forum topic is to find out what you like about the Zip series. Has it been the concepts I have been applying in each pump action model? Was it the styling, which was more spontaneous and sci-fi? Maybe it was a hidden preference for the ergonomics of pump action. The truth is, I don't know and I want you knexer's to tell me what you like or dislike about my Zips and Competitors. Using this information I will be able to build a better Competitor or maybe just refocus on building Zip4.

Hi guyz..is it possible to design a waveform genarator with touch technology...i mean its selectors, and other buttons be put in a  touch LCD screen..i  thnk u know what i mean...ty.. responses will be great help... (sory for my english.)

I think you got it.

Hi, I was wondring what is wrong with a ipod touch 4g that suffered minor impact trama (no cracks on lcd or screen). When you press the lock button, the screen turns on, but it has a lot of white thin lines going down it and the picture looks distorted. You can unlock it, but it still has the lines and the screen is still distorted. Can you tell me the physical problem and solution please?

I took apart a stud finder to see how it worked. Did a quick google search and figured out they work similar to tough sensitive lamps (capacitance). So after soldering an on off switch to replace the push button on it, I taped it to my door, and fine tuned the sensitivity wheel. Now when someone touches the doorknob (on either side of the door), It lights ups.

My brother loves drawing and he has a friend who has something called a bamboo pad.  It doesn't have a screen which is why I found it questionable.  So we thought we might look for a touch screen he could use.  We had very little luck finding one that seemed like it fit the purpose.  Even those bamboo peoples' didn't look like they would do anything other than lines.  So we have a question.  Is it actually fairly easy to use a bamboo pad, and if not, what touch-screen could he use.

Hey :) i have a sweet idea of building a touch screen keyboard that's separate from the monitor. i kno their are already some on the market but it be way cooler if i could build one myself. after doing some research i found the easiest way with the most versatility would be to have a touch screen ontop of a display and have the display then attached to a chip which would relay the image of the custom keyboard. the keyboard then would be hooked up to the computer and would function like a normal keyboard but soundless. :D the problem in all this planning is 1 i don't know how to put everything together, even though Ive been reading up , my knowledge of hardware design is minimal and 2 i don't know how to write programs, but if its any consolation im teaching my self simple programming like C++ but i doubt that will help. anyways , any suggestions Thanks a million Justin

I have a 4th Gen iPod with a cracked screen (corner) and it's lock button isn't working. The iPod can still be used and does turn on. I would like to see if anyone would be willing to buy it. I may be able to post an image.

I have a little toy that makes noise when you squeeze it that I want to give as a Christmas present, but tiny little hands have trouble doing the squeezing properly, so I want to do a little surgery on it so that the sound activates with just a gentle touch instead.  Such as if you flick it, pet it, pick it up... that sort of thing.  I know when I was little, we had a doll that was supposed to make noises when played with, but it was so sensitive that it would go off from just the blow of our AC.  My problem is, I've no idea what parts I need to do this.  Can anybody help point me in the right direction?  And I only have about a three inches to work in, so it needs to be fairly small. Thanks.

Hi everyone, Tactiontape is a one-dimensional touch sensor that curves. It's designed to make building interactive physical prototypes easier, even ones with non-planar or complex surface geometry. It functions as a flexible potentiometer and uses a strip of graphite to express a linearly resistive electrical signal, one that corresponds to how far along the tape you've touched. Each sensor is hand-made using materials from an art supply store. Here's a demo: http://www.youtube.com/watch?v=0ggYn70TpZY For purchasing, photos, and more detail: http://www.etsy.com/listing/87989636/tactiontape-curved-touch-sensors-for

Hello, I'm currently trying to use a touchscreen that has 4 wires but 8 pins. I have a connector with 8 outputs, but I read some topics about touchscreens and everybody uses just 4 of them. So, right now, I'm using just 4 pins (It works with some noises) and my question is: If I use the 8 pins it will be better? If yes, how to connect them? Here is the touchscreen model: https://www.digikey.com/product-detail/en/nkk-switches/FTAS00-104AS4/360-3037-ND/4508087 I'm putting the screen configuration as an attachment.

Is there a method for jailbreaking an iPod Touch 4G that will NOT leave an iPod unable to update via iTunes?
