Planning to make a electrical device ?

Hi, basically I am planning to make a device,  like a elongating stick/rod. Based on a meter (scale) it should keep elongating, when the current is supplied. For instance say we have  rod of 3 feet  in length (3 pieces).  The rod will be in the device, when I supply the power to the device, it should protrude to 1 feet and then again for more power another 1 more feet and more power another one more feet. Can some one pls help. Thanks.

How do you make an Electro Magnetic Pulse Device? Answered

I would like to make and EMP device to blow an RFID. I understand that it is a capacitor and a coil.  And that you charge the capacitor up and then discharge it through the coil.  But what size and voltage should the capacitor be, and at what what voltage do you charge it and how thick does the wire need to be? Is it all about the voltage of the cap (12 volt or 400 volt)  or is it more about the size of the cap? Thanks

Antistatic solution?

Asked by Monger 7 years ago

Looking for directions for a device made in electric shop class that would let the user shock himself.

I remember that it was mounted on a block of wood, and had a metal plate attached to one side with holes in it.  It used a D battery and a copper wire coil.  A rectangular piece of copper with a copper probe attached was held by the user.  You would try to pass the probe through the holes in the metal plate; if you touched the plate, you were shocked. Does anyone have directions for something like this?

How To Create Frequency Specific Microcurrent?

Curious if some of the electronic gurus might have the answer to this. I am looking to build a two channel (A/B) microcurrent (allowing from 20 - 600 microamps) with selectable frequencies ranging from 3 to 970 Hz). This is based on a medical device that I'm looking to replicate. I've figured out some of this but again, considering the wealth of knowledge here I'm sure some would know the best way to build this. Oh yeah, I figure using a rechargeable battery which could be whatever voltage is best recommended. So what do you think???

Is there a DIY Arduino or Raspberry Pi Coordinate Measuring Machine published in "Instructables"? Answered

I wish to build a coordinate machine using x-y-z movements controlled by a microprocessor that can measure a scale model by touch of a probe or by reflection of a microwave.  The base machine would handle an envelope of 8" x 8" x 8" and use one or a combination of the best of the CNC laser cutters, 3D printers, etc.  Whether the microwave non-contact, crash avoidance, technology is sensitive enough would be interesting.  A couple of contact probe articles have been published and are the basis of commercial "Coordinate Measuring Machines" (CMM) and would be interesting if they are sensitive enough as a DIY project.  The end result would be to write a file with the x-y-z coordinates of say a model car, and knowing the scale of the model, one could multiply the data by the scale factor and have "Full Scale" coordinates of the cars' surface for building a kit car body.  A 1939 version of this project is on display at the CORD/AUBURN  Museum in Auburn, Indiana.  A 1939 Cord in 1:10 scale is shown as a clay model with half of the car finished.  The coordinate machine's purpose was to measure the right hand side completed in clay and produce a finished 1:10 scale model by finishing the left hand side symmetrically from data obtained from the opposite side. While interesting, it is a manual machine.  I am seeking an electronic, programmable, DIY version.

Hugging device

We are in search for ideas and/or off-the-shelf solutions for a mobility and toileting issue in response to the following request: "I apologize for posting again so soon, but I forgot to describe my disability, and why I'm physically unable to hug someone. I was born with a rare form of Muscular Dystrophy called Nemaline Myopathy. My disability affects me in many ways, but in this case, I'm unable to independently raise my arms, wrap them around someone, and have them stay in place. A device I'm seeking would have the ability to suspend my arms in the air, and be able to bring them together. One suggestion was to somehow hook it up to a motor, and operate the device by a remote. Also, when I was a kid, I had a device that was like a sling for my arms. The two slings were attached to two separate metal rods on both sides of me that were able to attach and detach from the back of my wheelchair. Someone would slide my arms into the sleeves, and I was able to bring my arms together, or do various tasks, like typing, with my arms suspended in the sling. I do have the strength to squeeze my arms together, but without assistance, my arms eventually do slide down due to gravity. A device similar to the sling idea would probably be ideal, plus no motor or electronic devices would be needed. I realize that this project could be timely, and possibly expensive, but to me it's worth it. I'd love to be able to give someone that I care about a real hug, and experience another form of intimacy and closeness." Happy to hear your ideas!

Computer as composite display device

Hi, Okay, here is my problem: I found in my garage a small video camera (not with tape, recording or anything, it just plugs directly into the tv to watch the area) which I had got some years ago, now I would like to start using it again, however I don't think the only tv in the house is a good monitor (it doesn't provide any recording and it already has all rca inputs in use). What I would like to do is connect it to my pc and view the video (and listen to audio) on my computer, then like this I can also record video to the HDD if necessary. The camera has a composite video output and a mono audio output. Thanks, All help is appreciated. P.S. The problem with TV tuner cards is that I already have one, but it is not with me so I can not use it, on the other hand since I do already HAVE one I am not going to buy another one. Damn it when I thought that tuner card was not going to be useful and decided not to take it with me.

Mobile Virtual Presence Device? Answered

Right, so in "The Big Bang Theory" there is an episode where Sheldon makes an rc stand with a monitor on, and it has live footage of his face on it.  There are ways to do this, but they all seem to point to using an rc car with a 10 metre range and 30 minutes battery.  The flaw with this, is that if you want to be at work using one, or at someone's house with it, then you're gonna need a lot more than 10 metres!  How can you make it so that you can control it anywhere, either using wifi or just connecting somehow?  (I'm sorry, I'm really bad at electronics, so excuse my poor understanding.)  As an example, you don't need wifi to text someone, so do you need it to control an rc vehicle?  Ideally, I'd like to make one at about £300-£400, and as like the one from the big bang theory as possible, so not just a tiny stand that people have to keep charging and you have to crane your neck to see.  I'd be happy to use a £60 tablet with skype for the video, but what I'm mainly concerned about is how to control the rc stand/vehicle from a distance away. Thanks a lot! -Finzaz
