A/V + Power Switcher

I think it would be beneficial to create an A/V switcher that has power plugs for each of the slots in addition to the a/v components. So if you select #2 for example, it would power only #2 as well as display whatever is plugged in to #2. Could someone create a tutorial for this? Thanks

LED indicator for A/V selector

Hi! A while ago, i made an A/V selector, and it worked quite well. It had a small design issue, which is, having the ports at the front, where the switches are, and I want to upgrade it a little bit. The idea is, put on the front the switches with a LED on each input, and when I switch the selected input, the selected LED will also light. I've been looking around, and the A/V voltages are around 1 volt. The switch I have, it can handle 3 circuits at the same time (Video, Left and Right) but it has 3 rows as a conmutator or something. The thing is, i need your help in order to connect the LED. I've been thinking about using the unused row of the switch, but I don't know how, or, place a transistor when the Video input comes across the switch, but I don't know what kind of transistor will do. Thanks in advance I attach a diagram of what is now, with 5 inputs, showing only 2 of them, to have a brief idea

The KLS V.2 *Updated*

Can I get a W00T for summer??? Now that summer is here I have had a bit of extra time to dedicate to my gun building, and I have completed my Semi Auto.  The Kinetic Last Stand is a small, compact semi auto rifle that utilizes 4-shot low cap removable mags and has a firing mechanism that originated from Louis XIV's semi auto, just a bit more complex.  My idea of this has been around since christmas when I posted pictures of my first attempt of this gun, however It required too much energy to pull the trigger that was necessary, and so I created the V.2, which uses a simpler, more efficient trigger that allows you to utilize the energy of 2 #64's with little effort.  The only downside is the mag capacity, which can be improved by a about 1.5 for every half moon connector that the mag, and in turn, stock, is extended.   Thats about it...the video will demonstrate just how impressive this gun is. Maxed out means the maximum amount of power I would use for a war for the sake of keeping a high rate of fire. Let me know what you think!

The Kinetic Rifle V.1

Here it is: the bullpup, tube mag, bolt-action, pump-action, sling semi-repeater.  This is by far my most favorite gun I have ever built.   The reason I call it a "semi-repeater" is because while it has a magazine, loading it involves a two-step process of pulling back the rubber band and then pulling the pump.  Therefore you don't have to load each individual bullet into the barrel by hand, the pump does that for you, but the band still has to be pulled back manually.  The gun was originally intended to have the pump bull back the band as well, but to do so the pullback distance would have to be greater, requiring a larger barrel to house a longer pullback, requiring pieces I just don't have.  When I get the pieces I am going to make the pump pull the band back, and I will post that as the V.2. What I love about this gun is that it takes many concepts and combines them to work in sync with one another.  I also like the fact that there is almost no limit to how powerful you can make this gun, since the ratchet can hold an incredible amount of tension.  Overall it is an incredible gun, averaging ~60ft with the 1 band used in the video.  Though it isn't the most reasonable choice for a war (it only holds 4 shots in the mag and is huge), it is well on its way to becoming the most efficient knex repeater out there. -Kinetic iMovie wrecks.

6 V DC to 4.5 V DC for bike lights (LED)?

Have a Shimano front wheel with hub dynamo. It generates 6 V DC, voltage regulated. I want to convert some ready to use LED gadgets for illuminating the bike and the road during these dark days. Many of them use 3 button cells or AA(A) batteries. A small circuit board in the head light (have a huge motorcycle front armature ready) must convert the voltage. When I look for a 'buck puck', it seems that this lowering step is too small for what's available. true or not???

Some questions about A/V stuff (home theater)

Hi all! Hope I got the right place for this.  I figured that there's someone in this community who can help me. My A/V receiver is about to give up the ghost.  A number of channels no longer work, and the sound is pretty fuzzy.  I know I need to replace it. I've always been terrible with A/V stuff.  I'm not sure what direction to go as far as replacing it goes.  Here's my issue:  The room I have the receiver in is small, so I don't need a lot of oomph.  I also don't have a way to run wires to rear speakers without people tripping over them.  I've gone without rear sound for a long time now.  I've never seen a set of wireless speakers that are reliable, so that seems like a poor option. I can't really do a "home theater in a box" setup, because they don't have enough inputs to add all of my stuff.  The things that currently run through the receiver are my computer (which runs our TV through a tuner card), a wii, an xbox 360, and a dvd player.  None of them are HDMI.  I use RCA cables for everything. The other thing that looked interesting is a sound bar, as they can apparently replicate surround sound without the rear speakers, but they seem to have the same problem that the "theater in a box" packages have. I don't know anything about receivers.  For example, I don't know if it makes sense to use a 5.1 receiver if I'm only running R, L, and Center speakers from it. Anyway... I'm not looking for brands or models necessarily, but rather, setup suggestions.  What kinds of things should I be looking into?  I can't be the only person with this kind of problem. Any advice that some of you A/V gurus can offer would be greatly appreciated!  The cheaper the better, here... as I don't use it all that much.  :) Thanks!

A/V Cord to Typical Stereo Wires? Answered

I have a surround sound speaker system that only takes the typical stereo wires (you know, positive and negative electrode inputs for left and right side). I also have a stereo reciever that only provides A/V outputs. I was pondering how I could make these work when I realized that, even with an A/V cord, it still needs to make a complete circuit. Thus the cord needs to have two wires going through it, and the plug had a way to complete that circuit. Now that I know this, I want to know if I can cut the plug off of one end, strip the wires apart, and plug those wire ends in my subwoofer? If anyone knows if this is possible, please let me know! And please help me determine which wires are positive and negative current. THANKS!

The Power of Making: V&A Museum, London

"Making is the most powerful way that we solve problems, express ideas and shape our world. What and how we make defines who we are, and communicates who we want to be... Many people think that craft is a matter of executing a preconceived form or idea, something that already exists in the mind or on paper. Yet making is also an active way of thinking, something which can be carried out with no particular goal in mind. In fact, this is a situation where innovation is very likely to occur. Even when making is experimental and open-ended, it observes rules. Craft always involves parameters, imposed by materials, tools, scale and the physical body of the maker. Sometimes in making, things go wrong. An unskilled maker, hitting the limits of their ability, might just stop. An expert, though, will find a way through the problem, constantly unfolding new possibilities within the process." I just found out about an exhibition at the Victoria and Albert Museum in London; The Power of Making. The V&A; and Crafts Council celebrate the role of making in our lives by presenting an eclectic selection of over 100 exquisitely crafted objects, ranging from a life-size crochet bear to a ceramic eye patch, a fine metal flute to dry stone walling. Power of Making is a cabinet of curiosities showing works by both amateurs and leading makers from around the world to present a snapshot of making in our time. The exhibition showcases works made using a diverse range of skills and explores how materials can be used in imaginative and spectacular ways, whether for medical innovation, entertainment, social networking or artistic endeavour. Making is the most powerful way that we solve problems, express ideas and shape our world. What and how we make defines who we are, and communicates who we want to be. For many people, making is critical for survival. For others, it is a chosen vocation: a way of thinking, inventing and innovating. And for some it is simply a delight to be able to shape a material and say ‘I made that’. The power of making is that it fulfills each of these human needs and desires. Those whose craft and ingenuity reach the very highest levels can create amazing things. But making is something everyone can do. The knowledge of how to make – both everyday objects and highly-skilled creations – is one of humanity’s most precious resources. Items on show include a life-sized crocheted bear, an electric guitar worn on a high heel, extreme cake decorating, and our old friend the Makerbot. The show also includes a Tinkerspace - meet designers, and see Making in action

16 V AC POINT MOTOR?

Hi there, I would like to say hi to the instructables members for a start. Hi! I have always enjoyed reading from this site and I see that there is a lot of help in the topics posted here. I am a Computer Technician that now wants to play in the hardware game (Are you all enjoying Windows 10?). So I'm starting small with an arduino and the raspberry pi, (not side by side yet,) a few motors, servo's, 7" color crystal display, and other things that I have salvaged from stuff or found cheap. I have a few of these CD drive eject motors with lil' knobs I was reading this post about how to make an electric magnet as I am trying to manually make my own point motor for my model train set.  For those in and not in the know, here is some information about what I am trying to do. Create 2 electric magnet coils that pull or repel a nail or metal bar where an upright pin ~2-4 mm is able to travel a distance of ~6-8mm (oo Gauge) in order to change a track piece from one position of a "junction point" to the other, allowing the train to change track or take another route. I would like to try and do this myself as I have plenty of different types of gauge wire, dpdt's (for pole switch?), nails or metal bars(to act as middle pin maybe and bar to be pulled back and forth), diodes (for bridge rectifier) , resistors (to calm the voltage down if I have to as I think it will get rather warm else), a constant power supply (16V ac admittedly)  and plenty of BABY BABY small yet rather strong.. magnets..etc.. ( BTW These were taken from a motor that was inside some water speakers, for perfect reasons the motor had a spin disc attached to it with 3 very small magnets, then in the water compartment there is a spin disc with more magnets attached and a wirly-gig to create the siphon to jettison the water up when the music is played so I now own 60 of the little blighters, (that's if i need them at all to be honest I'm a little lost in this idea))  So please take me as a n00b and please help me in going about this. Yes I could go buy one, but what does that achieve, when I believe I have everything I need at my fingertips and I wish to learn. I presume I will need to deal with the constant AC in order to be able to make a switch to change the polarity of the two coils in order to pull or repel the magnet or nail in either direction to then move the tracks junction from one line to another. I'm going to try and make some coils, in some rather thin wire that is insulated.  Thanks again for any replies. EOL

K'NEX PMR-30 V.1

Hey guys! Well, it has been a while since I have made a pistol (yes, I know, I just posted my FN Five-Seven 'ible, but I had taken those pictures a long time ago), so I decided to make a gun I saw in my March 2014 issue of Guns and Ammo Magazine, the Kel Tec PMR0-30.  The original shoots .22 Magnum, has a 30 + 1 magazine capacity, and only costs about $415.00 U.S. dollars. Mine shoots tan/blue clips/connectors, has a 10 - 13 +1 magazine capacity, and only uses about 100 - 150 pieces. I have yet to fire the thing, so this forum topic is just to gauge what you guys think about it. Credit: Most the the handle/grip comes from Blue Mullet 2's Pistole Makarov. Everything else is pretty much original. Features: - Only 8 in. long - 10 - 13 +1 magazine capacity (this can be easily increased) - Nice setup overall - Semi-comfortable handle/grip - Nice sight set (I forgot to take a pic of them) - Easily modifiable Well, that is all the time I have to write for right now, I got lunch calling my name!
