Strobing Using RGB LEDs Instead Of Flash Tubes

publicimage over 1 year ago

I would like to create a something like a strobe but with very bright RGB LEDs.

Can anyone suggest a product?

Can I use a MOSFET to power something like this?

Which Arduino Would work best?

Please help!

Hi,

It would be good to mention the actual use-case (e.g. photography? nightclub?). Otherwise, you may end up with a solution that doesn't meet your needs.

Its application is for something like a night club.

So more like flashing lights than a strobe...

I want it to flash as if it was a xenon tube. Just like a camera, but very quickly(about 60 times a second). I see many of these things on Amazon, but I want to flash just like a party strobe but with shifting colors.

Both Amazon and AliExpress has LED strobe party lights. Hard to beat Ali’s price, unless you already have the components on hand. You can always reverse engineer and replace the controller with an Arduino Pro mini - that’s what I would do if I want custom party effects.

Thank you for the suggestion. Is there a safe way to deal with these types of products when reverse engineering?

Reverse engineering can be done by redrawing the schematics without powering it up, so at that point it’s safe. Depending on your skills, it might not work again or be safe again….

Another way is to use the leds, the enclosure and the driver (presumably mosfet) and rebuild the rest of the controls, and using a safe external power brick.

Geez, you cant even buy the LEDs for 6 bucks, let alone thrown in an enclosure and pots with knobs. For sure if the LEDs are change color based on loudest sound frequency and flash according to the bass beat - add a electret mike and a couple filters or equalizer IC MSGEQ7 , battery or power supply , cost adds up.
