LED's on UMO?

[the_schire 3]

Hey guys, I've been seeing a lot of fancy looking UMO's and UMO+ with LED strips in the frame, and I would like to do this with mine. I have some 12v blue flex LED strips lying around, but I seem to recall hearing that the UMO uses 19v for all of its electronics. How might I go about adding some sexy LED's to my machine? Thanks.

Hi @The_Schire, here is another topic covering the same.

Have a look at it and let me know if you have any further questions!

But that thread is discussing the umo+, which I read uses the um2 board. Do the two have the same board? I have a umo, which I read uses 19v for power. Also, does this mean they have the same layout and would have the same 12v connector on the board?

It's hard to see from your picture, but did you also wire in those three caps on your board? Also, how big of a heat sink would be required? I have some small ones that used to be on some bad stepper drivers. Would that be enough, or would the LM7812 require more?

I skipped the caps If you use a 7812, there is some (quite?) some heat, just to be sure I added a heat sink I had somewhere Using a DC DC converter should be the best solution.

Using a DC DC converter should be the best solution.

 

Well, if a lm7812 doesn't put out that much heat, I think a small heat sink on either side will be more than enough.

I read in that thread that caps were added to compensate for flickering?

Lastly, what port did you plug all this into on the board? I read that people were using the heated bed power? But wouldn't that not always be powered?

You can pick multiple locations. I believe I picked the 19V leds port. But if you pick the HB you can turn it on and off using Gcode I opted for a switch hidden in the bottom.

Yeah I was thinking about getting a silver 16mm anti vandal switch with blue LED to match my strips. Thanks for the help!
