Pulse LED circuit

[asuperpower]

How do I connect BitFenix Alchemy LED strips to this?

@asuperpower

You won't be able too. This is only good for ONE LED. Probably look for a modified circuit or something similiar to this.

[asuperpower]

@xcentriqx But I saw your video with the pulsing LED's in the HAF X and really want to do something similar. :/ Thank you for replying though.

[xcentriqx]

@asuperpower yeah I had the guy who I got the parts from help me put together a microchip.

hi, i saw in a previous comment you said to replace the 33k ohm resistor with the potentiometer, i bought a potentiometer insteand of the 33k ohm resistor, but the potentiometer has three possible connections, which ones do i connect? thanks

[alexizhernan]

article doesnt show where to connect power.. can anyone tell me where to conect the 2 power cables?

thanks

[xcentriqx]

@alexizhernan i think i hooked it up with pins 1 and 3. just trial and error.

[dethecus7]

i want to do the same circuit. i followed the instructions from the link but i really can't achieve the same result with you. Can you post the circuit that you used or describe the things that you did or upload picture of the circuit from both sides please!?

Hey @centriqx, I am working on a prototype that uses LED light and I need a pulse LED circuit to finalize the design. I think you circuit with adjustable fade timing is absolutely PERFECT and I would like to know how to construct the same thing and where to get the supplies? This is exactly what I need.

[patowlmc2]

I'm trying to arrange 12 leds in a circle. I want to light one at a time, and when that one turns of, i wanna light the next one.

How could I do that?

[xcentriqx]

@patowlmc2 You need a micro controller to do that. This is merely a test I followed from the schematic. Only good for 1 LED.

[tobster9103]

@patowlmc2 you actually do not need a micro controller that needs programing. try to find a schematic for a "10 step counter". all that is needed are a few resistors, capacitors, a 555, a 4017 decade counter and your leds. I have a schematic on an app for my ipod called "ee toolkit". not trying to sell you on the app but that is where I have seen this circuit. Hope this helps you out.

[Bvzijverden]

That schematic doesn't work for me either :( If trieded it a million times, until the leg of the 555 timer broke..

Change polarities, components, value's, but still nothing 

[rbcustoms81]

where do I get schematics for that.....I want to do that to my Terminator T-800 Eyes.......

[springsxj]

I've been wanting to do this for a while. How difficult would it be and what would I expect to encounter if I wanted to create a circuit for an LED that turned on during PC start up, pulsed at regular intervals for a few seconds and then went solid?

[georc16]

is it possible to turn the led off/on completely?

[xcentriqx]

@georc16 Yes. Grab yourself a pot with a switch.

[microchots]

hey! I tryed the schematic in the link you posted but doens't work!

can you give yours schematic? or post here with a video

I like the fade you get

[xcentriqx]

@microchots

As said in the description, I used the schematic in the info. Read the instructions carefully and don't take any shortcuts.

[vail0318]

@xcentriqx The schematic you have linked to does not have the adjuster on it.

[xcentriqx]

@vail0318 In the electrical components list:

33k resistor ( or a 100k potentiometer for adjustable fade times)

Replace the 33k resistor with a 100k pot (the adjuster). Hook it up with pins 1 and 3 (outside pins).

I am very interested in the circuit for this. If you could explain it that would be great. ONe thing I am very interested in: how much voltage is going in?

[xcentriqx]

@ditto125 its running of a 9v battery. there's supposed to be a resistor on the board but i already have a 470 Ohms resistor installed inline of the + wire on the LED.
