I’m looking for a solution that I’m hoping you can help me with. I built a custom car a while back (see website link). It has an electric radiator cooling fan that has two speeds. I want to use a single LED to let me know when the fan is on low speed vs. when it’s on high speed. I’ve seen plenty of RGB, RB, & YG tri & bi colored LED’s but I want to avoid greed & red as the LED is in close proximity to my turn signal indicators which are green & red usually indicates a failed ignition in automotive applications. I’d like a way to get two different intensities of yellow… a yellow/orange when the low speed is powered and then a more orange shade when the fan’s high speed is on. Is there such a thing as a Yellow/Orange bi-color LED? Or maybe a way to use Yellow for low speed & have both yellow & red on to mix & look more organge for high speed? Appreciate any help you can offer.

Thanks,

Rob

Hi. Do you accept sharing the C source code for the Aurora 48?

Thanks

You can power R48 with 5V regulated power, but I recommend putting a diode in series to drop the voltage a little (to about 4.3V).
As for triggering – you can use Arduino to toggle the switch. Switch on R48 is normally open, so by putting the Arduino pin that’s connected to the switch to low momentarily (about 80 ms) would advance the light patterns on R48.

R48 – can I use an Adrunio to trigger and power the unit? I’m not looking to program it, just add it to a project and toggle the display.

Is this possible?

Thanks

I’d like to software control two Aurora 12 bars from a PC, possibly thru a DMX512 box. I’ve seen the numerous SMD strips, but the spacing of the LEDs is not close enough for my applicaion. Please advise.

Thanks for the suggestion! I will check it out.

Hi, Thanks for the cool driver well done.

I found a simple fix for the 20 volt vgs problem. Just swap in an FQU11P06. it’s the same package, has a 30 volt vgs, is faster, cost the same and just as easy to get.

As the LM393 can handle 30 volts, it makes it a perfect match :)

Hi Aki! You are a true artist. I’ve been doing artsy things with led’s for years. I bought an assembled version of your mini 18 last year. Still haven’t decided what to do with it yet except to wear it in the middle of my chest with a crazy Ironman costume :) Anyway, I’m fascinated with the Aurora 18×18 with an audio interface & using it for my next art project. I drilled 15 5mm random holes in a 4′x4′ black 1/2′ Gatorfoam board, glued mostly white & a few slow-fade rgb’s & covered my ceiling with the panels. It looks stunning & feels very soothing for room light.
So…drilling 324 holes in a spiral spread out on a 4′x4′ panel & mounting the rgb’s then connecting the 2′ lead wires to the Aurora pcb will take a few tedious days. I think it will look breathtaking & be well worth the effort. I assembled a Heathkit color tv when I was 12. I’m not experienced with smd’s so if it you could mount everything but the rgb’s & resistors, which is most of the work, it would be greatly appreciated & save me some problems. I’ll just use th resistors since I have lots of room. Also program the pic & add a “through hole” audio kit.
I’ll shoot some video when I’m done & you can post it if you like. Send me a price & I’ll send ya some money! Thanks & keep on creating:) Chris

Hello Led Artist, congratulations for your work…
I’m an artist from France, I have a question about your Color Organ triple deluxe..can the audio jack be replaced by a microphone? to avoid to have a cable connected to the color organ?? thanks for your help

Hi. I will buy from your aurora 12 and Audio Interface Kit for Aurora (through-hole version), 2 months, and still do not get the parcel, the parcel is registered on behalf Linas Jagminas from Germany. If you can, check. Thank you.
