Momentary flashing lights

What is the easiest/simplest method of making a flashing light (preferably a small string of LED's or a piece of EL tape) connected to a momentary push switch? no timer or any other complication just lights that will flash on and off until the button is released. i want to make a flashing indicator light and switch small enough to mount on a ring that i can wear on my pointing finger so that the button hits the back of my hand as i straighten my finger to point and the light flashes only until i curl my finger to release the switch.

Flashing LED?

I recently took apart a flashlight, which features flashing LED's. They only have 2 leads each. One flashes on and off, and the other blue and red. I can see a small black dot inside them, is this some type of transistor? I am also wondering if there is a way to get a bi-color (3 leads) LED to flash using a transistor. What kind would i nedd, and how would i nedd to hook it up? ( diagram appreciated)

synchonized flash light for cheap?

Also posted in "burning question " forum Hi, I am looking for someone who could do an synchonized flash light such as this one but for much cheaper ;-) The challenge is on synchronizing the camera with the flashlight, if possible wireless. The light itself and the diffuseur are no real topic. The use of such devices helps a lot when taking pics for your I'bles or your ETSY shop if you have one. Thx B

Circuit to flash a bank of lights

I have a bank of 30 x 6 volt lamps in an old computer console and I am trying to find a circuit to flash them in a random pattern. Ideally the lamps will be driven from a chip rather than individual transistors. I'm perfectly capable of building the circuit, but not designing it. Can anyone point me in the right direction please? Thank you.

Lighthouse pulsing light

Hi all - I am building a wooden model lighthouse, it will stand 5 feet tall and become my driveway landmark. I have been searching for a good light circuit, a non-LED version, preferably using 120v AC. I would like the light to just do a slow flash or pulse and haven't found a circuit anywhere. I did find one SCR simple circuit using a high rated capacitor, but I am looking for more options. I have a coloured halogen which should do the job well enough. So have any of you brainiacs come across any circuits close to this description - thank you for reading / responding. Bill

Flashing LED usb

I'm not really sure where to start with this, but in the end I's like an LED strobe where I can control how fast is flashes precisely (for example 5khz). My Ideas so far is you have an LED hooked up to my laptop via usb with a simple program to control the speed and how many times it flashes. Right now I've got LED's and usb's and 100ohm resisters if i need them. From what I've read I don't think I can control the usb port's power so I'm assuming I need a driver board or something? I'd love some help with this but I assume I've been too vague, mostly because I'm not sure what i'm talking about. Any help I can get would be amazing. Thanks

Light circuit that flashes an LED once when a light is detected? Answered

I'm kinda a new to circuits and i would really like your help guys! I'm trying to create a circuit that flashes an LED once if light is detected. I also want it with a 2-3secs delay which means after the LED flashes once the circuit turns off for 2-3secs (even if light was detected after the led flashes it will not flash again until after 2-3secs). Can i use a 555 timer to do so...and if yes how is the setup.

Flashing LED project?

I have undertaken a sign project for my work that involves LEDs flashing in sequence. We are a Fire and EMS education program and want something that is going to grab attention. At first the project was supposed to be just solid burning lights but has been changed. I'm guessing they want something like the old style movie poster chasing lights or alternating flash between 3 sets of LEDs. It's a little more advanced than I had planned and don't know where to start as far as components go. I've already got the switch they want me to use,  it is very similar to a toggle switch but has a safety cap. My sign is a little larger than a standard letter size paper and I'm thinking 10 or 15 lights across the top should look pretty cool. Any suggestions on where to start or what I need? Thanks, Matt   This is the switch: http://www.radioshack.com/product/index.jsp?productId=2062493   The photo I've included gives you an idea of what it is we do.

music lights idea

Well I've been working on this project for a while now and the design has changed many times. I have also asked several questions based on the ideas. My latest idea is to make 3 different sets of lights flash to music using the 3 outputs of a 5.1 system on a computer. I know this may sound confusing but what I mean is the orange, black and green outputs which control the rear, front and center/subwoofer of a 5.1 surround system. Do you think this could work? If so then I suppose I would use just the right channel of each and possibly the ground connection (not sure whether I need it). Also if using transistors to make an electronic switch turning the lights on and off, would I need amplifiers? I only have 1 at the moment and even if I could get more they would almost certainly be different. If you know the answer to these questions please help and even I am successful the I will create an instructable on this. One more thing: Does anyone know whether the center of the center/sub connection is the tip or middle of the jack? Thanks, Jim

Vertigo Lights

A few years ago I was attending a Halloween attraction where a conversation started about seeing a red skull.  We asked a few of the actors and I got the name of the attraction's special effects person.  What we were seeing was a programmable sheet of red LEDs that would flash so fast that you could only see the after image.  The F/X guy called it Vertigo Lights.  I understand the concept, but wondered if anyone has come across anything like this.  Could this be controlled by an arduino, or would a program need to be written to control all of the lights simultaneously?  I haven't been able to find anything like it in any of my searches. Any clues would be great!

Audio Triggered by Light

Hello, I'm an absolute beginner and I would appreciate some help. I need to build a sensor that triggers sound either on Pro Tools/Logic Pro/Garage Band or any other kind of audio software when it detects a single red flash of light on it, much like the light a laser pointer would produce. The light will flash from left to right in intervals of 2.5 or 5 seconds apart. The sound is nothing too complicated. It's basically just single notes, pitched a fifth apart so for example, when the left light flashes, it needs to trigger middle C, then when the right light flashes, it needs to trigger G above middle C. Problem is, I do not know how to go about this and where to start. I would be deeply appreciative if someone could help me out here and point me in the right direction. Thank you!

Flashing LED problem?

Hi everyone. I mess around with HO scale slot cars and have had decent success lighting them with LEDs using track voltage and simple resistors to power them. I have ventured into the use of full wave rectifiers to smooth out the power and a small capacitor to eliminate the flicker. The problem I am having is when trying to use multiple blinking LEDs. Single blinking LEDs haven't caused any problems and I've had good results with them. The problem starts when I use more than one. I can get a pair of them to work on the bench with out any problem at all, but when they are soldered to the slot car chassis they might work for 3-5 minutes and then they stop blinking, and usually get hung up on one LED staying lit. What is even stranger is if I take a piece of brass rod and touch the anode of the dead LED, it will light up momentarily (and the other will go out). I only have so much room to work with so flashing circuits, large capacitors and voltage regulators are out of the question. Keep in mind, these cars are the size of a hot wheels or matchbox car, and the chassis uses up most of the internal space. Any help would be greatly appreciated!!!

Multi Flash Flasher circuit?

I am trying to make my own flasher controller for a pair of LED light modules.  The 12 volt, low amp draw lights are to be used on a golf cart that we use when the patrol cars are not needed on campus. Traffic control is the main use due to being able to put it anywhere the patrol cars will not go. The flash patterns can be any type as long as it is automatic, and keep changing, like the strobe lights on police, fire, and EMS units. Some have 4 patterns, some have up to 18 patterns. Any one have a diagram or circuit design that may work? Thanks for any help.

Help needed with flashing brake light microcontroller

Hi All New here and hope you can help me out. I am a biker in south africa and would like to put together an aditional brake light that flashed 4 times then go solid. Microcontroller will most likely be the easiest and have design one as follows. (the coding has been done) LED's to be used is 20mA at 2.2V My concern is that for the amount of LED"S (100) i want to use 1amp is not enough and therefore i am using a LM7810 to drop the voltage from 12V to 5V with a cap to increase the 1A output to 5A I wish to wire the LED's in parralel si if one pop's then it wont affect the rest of the LED's. Must i therefore still wire a resistor in front of every LED? (180ohm?) or can i wire in this LED before the LED matrix to give it a 2.2-2.3V throughout the LED matrix? Here is my design : http://i247.photobucket.com/albums/gg156/HannesNel/design_zps52f754cf.png 2nd EDIT : How about this? reworked the design a bit? Then i drop the 12v down to 2.5V needed for the LED's and no resistors needed? I also opped for the LM350 due to the higher amps it can handle http://i247.photobucket.com/albums/gg156/HannesNel/Untitled_zpsc9900901.png 3rd update: Now using super bright LED's with a rating of 2V and therfore will use row of 6 in series to give 12V...still need resistors when connecting the 6 banks of 6 LED each in parralel? http://i247.photobucket.com/albums/gg156/HannesNel/Untitled_zps684a2209.png

I need a circuit that will flash a light at fairly accurate regular timed intervals. Perhaps the easiest might be a battery circuit with LEDs, but flashing a mains-powered light would be OK if easier. It is for use as a light metronome, so I need to be able to vary it to between 40 and 200 flashes per minute. Have searched the net: lots of flashing circuits, but none that can be varied in tempo in a reasonably accurate way. Grateful for any thoughts!

led flash and fade. how?

Video of RavelightPicture of RavelightIm interested in building a product that utilises coloured LED lights with multiple flashing and fading patterns.I have pulled apart a few LED products and examined the PCB's and the components and have a general idea of what is going on, however it is all new to me, and im unsure of the possibilities that exist. For example, i didn't know you could get pcb's so small...Basically i need the power source to be the small button cell batteries (up to 6 if necessary, though 3 or 4 would be preferable). With at least 4 LEDs of different colours (RGB etc). A similar design to what I want to make is a flashing LED light stick like people use at raves that I found. It has a button that seems to simply complete a circuit momentarily, and pressing it down again and again, scrolls through its 9 different flashing patterns.I have seen various different LED toys that vary on this, but are basically the same idea.The thing that I don't understand (on top of a lot of other small things) is what is under the black blob on the PCB? Is this something like a 555 timer? an IC? And how are these programmed to give all the different patterns? is it a microchip?This thing cost me $3 from a shop. three dollars!! cheap as....this is what I want for my product. can anyone help me out to understand?I can post a picture up in the next couple of days if people can't understand what i'm talking about.Thanks
