backlit picture frame

Hello all, so, i got these really cool batiks (paintings on silk), and i would like to make frames for them with light inside, cuz they look really cool when backlit. AND to avoid any cords hanging out of my beautiful pictures i'd like to make them battery operated with an on/off switch. so, has anybody done it before? or got any ideas how to approach this, and what materials to buy. needless to say, cheaper is better :) the pictures are 11x11 inches and they don't have to be bright, just slightly glowing, so i was thinking to use some LED's, or El-wire, and vellum or matt plexyglass to diffuse the light. any help apprecialted. thanks, -m.

Help with wire trees

Does anyone know anything about wire trees? How about lapidary tecniques? I need help. I made a wire tree out of laquered wire and I wish to attach small, tumbled stones to the ends of the wires...This is for a rolling ball sculpture project. I plan to have several of these trees (hopefully copper wire; I think I have some) attached to polished spheres made of natural stone that are attached to the frame of the sculpture. The track has 1" or 1/2" glass/polished stone marbles that roll along a flame-soldered wire track that winds in and out of the branches of the trees. How do I attach these tiny stones to the ends of this tree without the fear of them falling off? Some kind of loop? Glue? Both? I'd greatly appreciate any suggestions or advice..

Will PVC piping bend under a wire tension? Answered

I'm looking to make a hot wire foam cutter, and have most of the setup all outlined. However, the 'bow' still need to be made, and I plan to use PVC. Reason being is I would like to be able to stick some four/three way bends on one ended as to allow me to stick the bow on a stand of sorts to make a band-saw style hot wire. But, question at hand: if I were to make a frame out of PCB piping for a hotwire, would the tension of the hotwire cause the frame to warp? And if so, what would be an equally cheap option for the frame? Thanks!

Wiring NES Controller to NIX Digital picture frame. HELP!

Hello All, I am a new member to hack-a-day and was wondering if people had input into a project that I am working on. Basically what I want to make is a portable portfolio viewer that is a bit more quirky than what I have seen thus far. A lot of people are presenting on Ipads and the like... not fun enough. I want to wire an NES (original nintendo) controller to a digital picture frame and add a rechargeable battery to make it portable. As for the frame the most cost effective that I have found so far is Nix Digital 10" http://www.nix-digital.com/digital-frame/nix-n-easy-x10b-10-inch-hi-resolution-digital-picture-frame there are cheap battery packs available on amazon but they seem kind of wimpy...only 2 hours. http://www.amazon.com/Aluratek-ADMPFB100-Universal-Battery-Digital/dp/B00145CUJY?SubscriptionId=0E73DDYC8NA0NSVWPE82&tag;=askville-20&linkCode;=xm2&camp;=2025&creative;=165953&creativeASIN;=B00145CUJY And the NES Controller I have a bunch of. Also a battery indicator would be a nice plus! if any one has a successful nixie (or other lower voltage numerical tube) tube battery indicator method I would be very interested in reading about that. I attached an image of the wiring I would like to accomplish Any input about this project would be awesome.

How do you wire a small amount (8-12) LED's, to be run off a small battery and with a switch? In Laymens terms if pos?

Hi, I'm framing a piece of art with a deep frame and would like to put between 8 and 12 LED's in the frame. I will be running the wires and  hiding the battery and switch in a rebate around the outside of the frame. i will drill small holes in the frame every 2-3 inches through the frame for the LED's to be pushed into so they sit just below the surface on the inside of the frame. What i need to know is how to do it? From the basic knowledge i have i would have a 9v battery Positive wire into a switch,negative wire into 1st LED, then link all LED's with wire until the last negative wire into battery.  How wrong am I? I need to know how long the battery would last as well. Also needs to be wireless as it going to hanging on a wall. Thanks for any suggestions and help.

How can I build wire frame animal and insect shapes?

I'd like to build wire frame shapes of lizards, geckos, insects and etc for lighting up at night. I've built a 4 foot gecko out of conduit tubing and fencing wire. It is very strong but was difficult to work with. I think there must be easier materials to work with. I've seen shapes made out of plastic filament, and then there are zoos that do the Christmas shows. Garden centers also sell the wire frame shapes for topiary. The typical size is going to be between 1 and 3 feet long. The material doesn't have to be hollow like tubing, it can be a solid like wire. Ideally, the material would be something I could heat up, bend to a design, then it would retain its shape when cool. A little flexibility is good but the design has to withstand being outdoors. Thanks for any tips.

Help? Chunk glass hanging lamp how-tos

Hiya, I'm a noob. I love the look of chunk glass lamps, and like hanging swag / pendant lamps, but the real thing is ridiculously expensive. So, I'd like to make one. The wiring is reasonably straightforward, any one of the kit things would work fine. Where I'm running into trouble is how to put it together. I know it's going to be heavy, which is ok; Elephant hooks from Amazon claim they can support a hundred pounds if put into a rafter.  What I'm looking for is how to make the thing to attach the glass to. A lot of the existing ones (If you search google for 'chunk glass lamp' you'll find what I'm interested in) use either molded lead or mortar. I'm kind of looking for a slightly lighter weight solution; I'd rather the weight be pretty rather than structural.  An idea I originally had was something like a 3d printed frame, maybe in sections that can snap together with a network of supports to glue the glass to, to allow a thin smear of mortar or clay or something to cover it, so the light only comes through the glass.  I know many of the original ones from the 60s and 70s were lucite vs glass, Big hunks of glass seem relatively easy to find, big hunks of plastic not so much. If anyone has a good source for either or both, I'd love to hear.  Be gentle, it's my first time here. :)  (Tried to attach a file, but I'm at work, and it looks like the network is nuking it. Just search google for 'chunk glass lamp' and you'll find dozens.)

When I touch the wires to the frame it sparks up, so there is a current going through. And also if I just hold a piece of wire on my hands and connect it to the transformer, it doesn’t heat up either.sorry no pics, i might have some in a couple of days.helps! or suggestions as to what the reason might be for it not working. i am trying to build model for school, alas i think the foam cutter itself is more of a project then what im building

electic generator

I have not made this yet, but my idea is building an electric generator using a bicycle wheel surrounded by a non turning metal frame. Tightly backed on the bicycle wheel would be permanent magnets arranged in a slant pointing in the same diection and outward toward the surrounding frame. On the frame would again be permanent magnets wrapped with copper wire slanting inward toward the bicycle wheel. The magnets facing each other would have like poles. North facing north or south facing south. I know this is just like an electric motor so far. You would get the electricity from the arrangement by placing a thin copper stip on the top of the frame. But different from the motor is the idea that like poles repel. once you gave the wheel a slight movement in the same direction that the magnets slant the wheel would turn until the magnetic energy would exhaust. You could make strong magnets using rebar wrapped in copper wire and use a inverter to change the AC in your house to DC and connect the current to the copper wire surrounding the rebar. Then when the magnetism of the rebar is sufficiently strong cut the rebar using a hack saw into small pieces to place in either the bicycle wheel or metal frame surrounding the wheel, I'm not sure of the electric power dynamics you could produce, but it would seem that using strong enough magnets could make a generator that could power as large a device with amperage/volts you can create. It might be used as a device to run your furnace blower or refrigerator in an emergency if the power produced was high enough. I think this would all depend on the strength of the magnets you produce. But if it works-you could have electric power from the magnets as an alternative to batteries or gas driven generators.

Simple (I hope) Treadmill Incline indicator

Hi,  I have an older treadmill that has a button to control the incline, but doesn't display the incline. I have a treadmill program app on my iPhone that guides me through a exercise session by telling me to set the speed and incline many times throughout the 30 minutes I am on the treadmill.  I would like to build something to display the incline as I adjust it.  I have just enough memory from all my childhood Radio Shack projects learning to not be afraid to attempt this and also the vast knowledge of the internet :) I have already calculated and marked the incline differences on the frame of the treadmill near my feet but I can't really see it well. I figure a small LED display would work best. I can visualize running wires up and down the frame to the LED display to an arm that will move with the treadmill while hitting contacts. I am sure I can get this to work but it sure seems like a lot of wires so I feel I am missing something. If anyone has any suggestions about an easy way to do this or can draw me a diagram of what I would need, I would be forever grateful. Thanks, Cindy in Indy

I have a question about My ROV control system.

I am building an ROV and I need to know whether this control board will work. I planed on Running 1 Cat5 and 1 set of speaker wires to control and run systems on-board. When I flip a switch on the control panel, a 3v signal is sent down the Cat5 wire to the base of a transistor, which opens the flow of power between the Emitter and collector. My main question is, does a transistor work as a switch? Example. A signal enters the Base and opens the other two connections. Is this right? Oh, and the other two pictures are what i plan for it to look like. I am building it using the motors from one project (posted recently) , the frame another, and my own control. I will post an instructable as soon as it is done.

Thus, I'm hoping somebody can help point me in the right direction with this hopeful project,

Free electricity for a bicycle headlamp

A really good bicycle headlamp needs quite a bit of electricity to make it bright and last a couple of hours. A dynamo requires extra leg power to operate. Yet, there are power distribution lines along the roads where I ride and they emit electro-magnetic lines of force. Imagine a coil of wire on the bicycle that follows the triangle portion of the bicycle frame and it receives these lines of force, converting them to a low voltage AC current. That current would then be passed through a bridge rectifier and a voltage regulator to charge normal size flashlight cells powering the light. Technically, it is probably illegal. Certainly it would be if you were using a coil of wire on your lawn positioned under the power lines to power your house. If it could be done safely, the power company would have a hard time tracking you. It is probably impractical, but it is interesting to ponder.

I have found that hand sanding down the edges on these pieces just takes too long to do. I am contemplating getting a sander but am wondering wether the flat surface of the belt sander will work for the curved pieces of glass, or if a wheel would get into the curve better. Anyone had any experience with either method?

Transformer modification? Answered

2 questions about transformers: - If a certain transformer (let's say, for a power amplifier) is needed, and for example, a microwave transformer is available, can the steel frame be cut to take out the secondary coil, to be replaced by a new one, and subsequently be re-attached (by clamps or so)? Would it need some treatment, like putting varnish, or oil over it?  Would this cutting and re- attaching cause a loss in efficiency, or cause heat build-up? Would it cause more noise in the output? - Some amps have a toroid transformer. Is this just fashionable or is it for a reason? Some industrial amps use sheets of copper instead of wire. Why is this better for industrial, why, and if not for common stuff...?

Paper airplane videography

Allow me to share the methods I used to make my video. I hope this will help somebody out there do it even better. First, was the problem of capturing the plane in flight. I had chosen to make a fast model. A bad choice, from the point of filming it fly. If I stand back far enough to catch the entire flight, it becomes just a dot and you cannot tell whether it is a plane or a stone inside a ball of paper. If I stand close enough so that it fills the frame, then it just ... is gone. My solution was to get the best of the flights I could grab, and fill in the rest of the time with the process of construction. You can see in the video the paper apparently folding itself. It isn't. You are seeing it being unfolded, pulled by fine wires, played backwards. I have tried to edit out the wires, but in some frames the results are glaringly obvious. The movie itself was captured by a camera pointed downwards and the plane being launched into its field of view. Seen from the side, the plane is just not discernible as a plane. So I had to get a view from the top or bottom. If the camera is pointed upwards, the bright sky obliterates everything else. I used Fast Movie Processor, VirtualDub and Irfanview as detailed in my instructable on Time Lapse Movies. And the still images were captured by my scanner. Using the scanner is not my idea, I learned it from Don Lancaster at www.tinaja.com Hope this helps, or is of interest to, somebody out there.

I have a REALLY quick question!

 I have one of these Air Rebound remote control cars, they are LOTS of fun, but  I haven't played it for a long time as the battery is degrading, and it only ever seems to last 30-40 minutes, even when the battery was new. I've just taken it apart and among some simple cleaning and putting a longer antenna wire in (the old one cleverly traveled along the frame and around the inside of the right wheel hub, but I'm sure the longer wire I just attached will help GREATLY. I have this REALLY quick question though and I want to know before I put it back together. Each motor (theres two) has a small ceramic resistor soldered between the + and - leads on the motor, on both of them. The only purpose I can figure this would serve is to LIMIT the speed/power of the motor, and waste battery power? But before I do something stupid I really want to know if there is a GOOD reason for why they put them there.

need a jig for cuttin styrofoam straight/smooth surfaces?

I'm trying to get into lost foam (aluminum) casting, so I just build a styrofoam cutter ("frame" with a hot-wire). It's pretty difficult to handle because it melts trough the styrofoam so quickly and it's hard to hold perfectly straight and every movement makes an impression in the styrofoam part. I need some ideas on how to make a jig that makes it easy(er) to make smooth surfaces in the styrofoam part, I was thinking something that adjusts the distance between the hot wire and the table/surface and then just slide the styrofoam across the table/surface through the hotwire for making plates (easy), but I need to be able to change the distancee between the surface and the hotwire for different thinknesses but also somehow be able to make angles and hopefully also somehow ROUND PIECES AND CYLINDERS :o hope you can give me some inputs :D and even better some pictures, drawings and links thianks!

Broken rice cooker: what is wrong with it and what is the flat thing?

We've had our second rice cooker fail (this Black&Decker; rice cooker replaced an Aroma rice cooker which failed). What happened was it started to stink and didn't cook well, then finally the thermal cutoff inside failed. I've already had the exact same problem with the previous Aroma rice cooker... let me explain: In that Aroma Rice cooker which failed, I replaced the thermal cutoff with a direct connection and it worked! Well sort of... It actually overheated all the time, but didn't heat the food very much. Inside the connections I had made were melting/burning and it was always stinking, so of course we did not use it anymore. So this means there was something else wrong with that rice cooker. It overheated for a reason, and removing the overheat protection caused it to overheat. Rice cookers are very simple, so I have no idea what the problem was (and is). The only suspect is some weird rectangular thing i've seen, where two wires go in; one to the switch and the other to the element. So with this Black & Decker rice cooker, which has been working for quite a while (maybe a year or two), it finally failed by overheating the same way the old rice cooker did when I removed the overheat protection. It stunk a bit and didn't heat up well, then the thermal cutoff broke and it became dead. Replacing the thermal cutoff won't fix it because it would just overheat again. So what is wrong? Is it that rectangular thing? I opened the rectangular thing... inside there is a sandwich of materials and a wire... The first layer is the top metal cover which covers it up (and also always becomes rusty). The second layer is a thin papery insulator (or I think it is). The third layer is the same kind of insulator, but cut and it has a thin wire wrapped around it connected to the two wires going to the whole thing. The fourth layer is another insulator like the second. And the fifth layer is the metal frame which all the previous layers sits into, and the frame is bent around them to hold it together, and it has a screwhole to attach it. What is this thing? Is it some resistor? Does it increase resistance as it heats up, to regulate the temperature? And could this be what failed?

acceptable angle of deflection for temporary support

Hi, I am in no way an engineer.  I'm trying to figure out what is an acceptable angle of deflection for a combination frame and hammock support.  I'm thinking of using the the 80/20 t-slot beams.  I want something that is portable, easily assembled/disassembled for moving, and lightweight.  I'm go to make a box in our garden to protect our plants and when the corn is big enough, move the box around to make a hammock support(chicken wire around the bottom part to keep the critters out).  It's basically a box 6 feet wide, 8 feet long and about 6 1/2 feet high. 4 beams to make a rectangle on the bottom, 4 uprights(1 in each corner), and another 4 beams on the top to make it more rigid.  Chicken wire will keep the pests out but let me in to relax until the corn is too high and I move the frame.  :)  I'll put the hammock diagonally from pole to pole; total weight with me and the hammock is about 250 pounds.  It will be anchored to the 2 uprights with 300lb chain at each end. Using the angle of deflection calculator from 8020.net, I found some beams that had 5mm deflection with 150lbs of dead weight in the center of the 6 foot span.  I thought that even if I anchored the hammock to the center of the 6 foot span, that would be 300 pounds, more than the 250 max the hammock and I will be.  And anchored in the center of the beam is the worst case scenario since I'll be anchored to the corners. But is that an acceptable amount of give in the beam?  It's not meant to be permanent.  I won't be in it more than 2 or 3 hours tops. Thanks!

Question about electrical safety for a project with a 60V Power Supply and a Nema 34 Motor?

Hi Instructables Community,I'm working on a project with someone where we are making a VR game that uses a stationary exercise for interaction. For example, if you turn up a hill in the game while exploring a map, it gets harder to pedal. The resistance on the exercise bike is controlled by turning a knob.The knob just controls a brake-like device that adds friction to the flywheel. We're just going to use a stepper motor to control the knob with a belt. We, somewhat unscientifically, compared the torque required to turn the knob on the bike to how much torque Nema 17 and Nema 23 motors require to pull parts of a 3D printer back and forth and decided we probably need to use the bigger NEMA 34 motor. The stepper motor driver and motor we are going to require a 50V or 60V, 5A DC power supply. The motor will need to be attached to the frame of the bike near the resistance knob.This is the stepper motor and driver we are planning on using. This is the power supply we are planning on using.The stationary bike we are using is made of steel and very heavy and will be moved around a lot when people want to try it or move it out of the way. I'm a little worried that since the bike will be moved around a lot and since the motor will be connected to the bike, that if a wire got pinched or damaged it could lead to an electrocution hazard. How can I make the electronics on this project as safe and fool-proof as possible?My plan for safety right now is:Use a GFCI power adaptor to power the power supply (link)Keep the power supply and driver in a metal, grounded project enclosure (link)Ground the steel frame of the stationary bike.Keep the project enclosure fixed to the stand of the bike so that it moves with the bike when the bike is moved out of the way.Put the wires to the motor in some sort of heavy-duty insulation or conduit that's securely fixed to the frame to avoid any pulling/s shearing. Any advice/feedback/recommendations would be greatly appreciated.I don't have any photos of the set-up right now since this project is still in the planning stage.

Tips on building a model Sumerian boat?

For a school project, I'm building a model of a Sumerian boat, about 3-4 feet long. (some quick background: the Sumerians created one of the earliest civilizations, and one of their inventions was the boat) Google Images can provide some images to base a design off of: http://images.google.com/images?q=sumerian%20boat It doesn't need to actually work or float, nor be very accurate. As long as it's not too fragile and has the general shape of the boat (which apparently resembles a canoe), it's okay. It should also be made from cheap materials so that it won't cost too much to make. Any ideas on how to constuct it? My idea is to make a wire frame, and wrap that with paper or cardboard, but as I have little experience with this, I don't know if it'll work.  Please help!
