Re: small superbright green LED panels?
You want small and bright? Wow, you want everything don't you?
Well, today is your lucky day! These little spots of sunshine will more than meet your desires. BTW, they are also available in red, blue, warm and cool white. Partner those LEDs with this LED driver and you will not only be able to light up the target, you will also be able to do it on command! Trust me on this, wear sunglasses when viewing them directly. |

Re: small superbright green LED panels?
The LED. They need something with good thermal conductivity to keep pulling the heat out of them. But that can be as easy as mounting it against some aluminum.

Re: small superbright green LED panels?
Dave, we used the white version of those LEDs on our underwater ROV Babs. They work pretty well. Heat sink...we want a heat sink..but we have some aluminum we can use to make that.

Re: small superbright green LED panels?
What did you use to mount it? As far as I can tell, they don't have any mounting holes per-se. Presumably you'd want something that is a good thermal conductor. I could see using bolts through the cutouts in the star, but I'd be worried about putting stress on the PCB that way. Or zip ties through the star loops and thermal paste between the PCB and the aluminum?

Re: small superbright green LED panels?
We used 4-40 screws with a nylon washer under it, and insluating material between the aluminum LED base, and the chunk of aluminum they are attached to. This is in Babs, aka Stanford in the movie Spare Parts.

Re: small superbright green LED panels?
Can anyone explain how to connect the LED driver to the RoboRio?

Re: small superbright green LED panels?
get a Spike relay, and use it to switch power on or off, if that's what you are trying to do.

Re: small superbright green LED panels?
Spikes are no longer sold - so long as you are not using it to control motors or other actuators, you can get an off the shelf relay for controlling any sort of lights on your bot.

Re: small superbright green LED panels?
Thanks for the update on Spikes...we have been using them for a long time, and have plenty, so I wasn't aware that you can't buy them.
Also interesting about the power supply, that makes life easy |
