a lamp that flickers

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

Battery Powered Lamp

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!

6-Volt Lamp

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.

Touch Lamp Switch?

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!

LED Lamp Buzzing (not a bulb)

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!

Help Making a Toaster Lamp

Kats, I need some help making a toaster lamp. Now I know what you’re thinking, “ I always wanted to make a toaster lamp!”. Well now’s 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 I’m 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 don’t 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, I’m 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 façade. Now that I’ve outlined what I want to do are there any electronics wizards out there who can design me a circuit to do this? Thanks Paul

A lamp from RGB LEDs

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?

Help making an LED lamp

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 :)
