Hi, I've discovered this site just yesterday.... I try to use the search engine but it doesn't help. I'm preparing a location for a video. Now, I need to simulate an almost broken lamp, you know, a lamp that flickers. We're using incandescent lamps. It is possible to build a switch (or something else) that can simulates this effect on an incandescent lamp? Tnx in advance, ciao

Personally, i think this lamps look very cool, both items are made from various pieces of old electrical hardware.I love how the design is rather simple, but complicated by the parts used.Made by the Flickr user Qvidja50.He saysThe lamp on the left is fabricated from a railroad signal switching relay manufactured by the General Railway Signal Company in 1924. The perforated cylinders were originally ink canisters designed for high-speed fabric printing. The light on the right is made from a water-cooled dual processor from an Apple G5 desktop computer. Other elements include an hour meter, aircraft compass and 40W LED bulbs.Check out the full Flickr set.Personally, i like the 'hanging bulb' one. Firstly as i love the way the bulbs hang down, that and the use of a Powermac G5 heatsink is a win for an apple user fanboy like myself.For anyone looking to enter the Epilog laser cutter contest. Whom may have some parts laying around, this is a good place to start your research.I have an old iMac stand that caitlinsdad said would make a good lamp.- gmjhowe

I have to make a battery powered lamp for a school project but having no experience or knowledge whatsoever in electronics I really need help! I'm using a halogen GU10 bulb which is 35W, 240V, toggle switch and 2 AA batteries. Can someone please explain how I would wire the light bulb to a toggle switch and batteries? Also, do I need a resistor anywhere? Apparentely halogen bulbs aren't really suitable for lamps, so should I change to a superbright LED? Thanks!

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 this 6-volt Lamp it's kind like what you would find in one those 6-volt flash lights except that this is like a stand alone lamp and it has two wires that come out of it but only seems to work at 6-volts, so I have a large 6-volt battery and a 7.5 volt output power adapter I was wondering if 7.5 volts would be too much power to use to power the lamp I don't want to blow it up. I don't know if it'll even work at 7.5 volts because I tried a 9-volt battery and it won't power on with it. The image is the same lamp I have except mine is connected to a base and has two wires that come out the bottom I would like to find another way to power it besides using a large 6-volt Battery. Any Suggestions.

I have a glass candy looking sort of jar that i would like to flip over and build a small black circular stand to mount it on. Then frost the jar to give it a more ambiant looking light (i like blue leds but not necessary). I also need the lamp to be decently bright some where in-between a traditional desk lamp and a bright night light. I also and going to make a decal to stick to the outside of the jar to give it an illustration on the lamp. I dont want a battery operated one if possible id like a plug in with a switch or something. Something on the efficient side i don't like replacing batteries all the time, rechargeable may work. On that note i have a desk lamp already not sure what kind and brand i can check though, its a halogen i think it has a plug and a dial that brightens and dims it, i am willing to destroy if for this project that dial would be perfect . So what i need is recommendation on what and where to buy for lighting and details on how to mount it. I can handled most of the design of the arrangement, glass and decal im all over. More or less i need a cheap and decently easy way to light it im not super experienced in leds or a lot of wiring, im sure i can do it, would just be easier to avoid all of that. Any help would be much appreciated

About a year ago, I came across this LED lamp that was on sale at my local Target store. It caught my eye because it had a little tray at the base of the lamp along with a USB port for charging my devices. Since the first time I plugged it in and turned it on, it makes a buzzing noise. At first it didn't bother me, but now that I am spending more time at my workbench it has become annoying. I understand it is kind of common for LED bulbs to do this because of the dimmer switch being outdated, however this lamp is not dimmable nor is it a "bulb" so to say. It's about 7-9 SMD LEDs on a circuit with a rocker switch. If it makes a difference, I do have my lamp plugged into a surge protector and don't have anything plugged into the USB port located at the base of the lamp. What can be done (other than throwing it away, of course) to stop the buzzing noise coming from the lamp? Thanks in advance!

I have changed all my internal lamps to 240 volt LEDs - I notice some LEDs are dimmable and some are not any one know why? As a supplemental question anyone know how they step down the 240 volts for the LEDs? I have yet to take one apart to see.
Question by rickharris | last reply
Kats, I need some help making a toaster lamp. Now I know what youâre thinking, â I always wanted to make a toaster lamp!â. Well nowâs your chance to help. In its simplest form a toaster lamp would be a base of a toaster with the top of a table lamp. The lamp operates like a normal lamp by pulling the string or turning the switch. The electronics in the toaster would be disabled or removed for safety reasons. This would be the simplest model. But I would like to build a model where you press the toaster lever down and the lamp lights up. To turn the light off you press the cancel button or press the toaster lever up. Furthermore the light-dark setting on the toaster would act as a dimmer switch for the lamp. The toaster heating elements would be disabled for safety reasons. Now a basic toaster works like this: When you push down on the handle, a plastic bar presses against the contacts and applies power to the circuit board. 120-volt power runs directly through the contacts to the nichrome wires to start toasting the bread. A simple circuit made up of transistors, resistors and capacitors turns on and supplies power to an electromagnet. The electromagnet attracts the piece of metal on the handle, holding the bread in the toaster. The simple circuit acts as a timer. A capacitor charges through a resistor, and when it reaches a certain voltage it cuts off the power to the electromagnet. The spring immediately pulls the two slices of bread up. In the process, the plastic bar rises and cuts off power to the toaster. Some of the problems Iâm facing are the voltage to the electromagnet and PC board is about 12 volts. If you bypass the nichrome wires that would send 120 volts to the PC board which would toast it. So we need a way to do that. Another problem is we donât want the capacitor to cut off power to the electromagnet, that would shut off the light. We could not charge the capacitor by putting a larger resistor before it, Iâm not sure how to do this. The ideal solution would be to gut the toasters electronics, replace it with a circuit that does what I want, and the toaster just becomes a faÃ§ade. Now that Iâve outlined what I want to do are there any electronics wizards out there who can design me a circuit to do this? Thanks Paul

Hi, I'm want to build a lamp from 63 RGB LEDs. I want to be able to change the intensity of each color. Is there something in my schematics that should be changed, for example do I even need the resistors after LEDs since I have the potentiometers. I think the values might need to be changed. The switches before resistors are to eliminate that color if the potentiometers won't do it. There should be also a main switch after the power supply.. Do I need anything else, so that it will work and to it will be safe? A bit offtopic, but if I would only use one color LEDs, would it be better to connect them to parallel or series?

Hello everyone, My first question in this forum to build a LED panel with parallel LED connections. Input: 220V AC Bright White LED 5mm I want to put 36 LED in a panel and want to use bridge connections which will power up both the LED panel and a 12V Battery simultaneously, so when the power goes it will take the power from the battery. Can anyone guide me with circuit? I am novice and have interest to make things like this for own use. Thank You MarlöPax

Alright, I want to make an LED grow light for my plants because the window I want to put them in doesn't get enough sun. I need quite a bit of light for this application and it will have to be on for a significant part of every day so LED is a must. I've been looking at the prices and it seems like the most economical option is to buy some LEDs off ebay, buy a driver... maybe some resistors... then mock up some kind of heat sink to connect them to. I was considering about 10-20 ten watt on chip LEDs. This light is going to be in a room I'm in a lot so I don't want to go with any funky colors. I'd like to just use daylight spectrum LEDs. Something around 6500k. Anyway, I'm thinking it makes the most sense to get one big driver to run all the LEDs rather than one driver for each. That just seems cheaper and frankly more interesting. But I need help understanding how to wire the whole thing together and understanding whether I need resistors etc. So I'm looking for some general help figuring out what to buy and then how to wire it all together. Thanks :)

Hi all, I have the following problem: I'm trying to use the electronic halogen light transformer to run with an LED lamp that came off an emergency lighting unit. THe Lamp works fine off a 12v battery but when connected to this transformer (and a rectifier with a capacitor) both the lamp and the transformer get really hot. THe transformer outputs 11.6v at 4.9A. It seems like the lamp is drawing all the current it can take from the transformer but it doesnt when connected to the battery? Whats going on here? THanks for all your imput!

Hello very good people, 1. Someone told me that I can connect a 3.8A led lamp to 100w driver 3A (constant current) because the driver will dimmer the lamp. Is this correct? 2. Is the driver that operates according to the capacity of the bulb (3.8A) or is the lamp that operates according to the capacity of the driver (3A)? The current of which one acts according to the other? Thank You

Here I have made a PPT presentation for making lamps, moodlights or whatever out of your monitors. I got the idea by seeing that holding a magnifying glass in front of my monitor gave a clean but tiny image on my wall, but the rest was bright and blurry like a moodlight. The file is given below. Save it, open it and use it.

Hello my friends, What about the voltage, Is the driver that operates according to the voltage capacity of the bulb (20-26v) or is the lamp that operates according to the capacity of the driver (20-36v)? The voltage of which one acts according to the other? Can I use a lamp of any voltage since this voltage is understood the ability of the driver (20-36)? the driver is the same amparage and constant current. Thank you a lot.

I wanna make steampunk lamp. I was thinking some kind a magical or science fictional lamp. Light that truns on when there's is a sound in a room, human voice or something like that. Turns off when no one is making sound. I don't know what to use as sound cather. I have old wooden candle leg. I think piezo is not right for cathing sounds like human voice in air. I don't wanna make lamp that turns off and on when I say on the mic something. I wanna make lamp that starts glowing when it catches sound. Turns off when it don't catch any sound like human vocie. I don't know what to use as sound cather. I think piezo element is not right. Maybe mic element or someting like that is better.
