Head LED ring

[Nicolinux 288]

Hi,

I've got one of these led rings and would like to mount it using this thing:

Where would I connect the led ring? I think it needs 12V.

Thanks,

Stefan

Those are very popular here with the remote controlled airplanes, namely the ducted-fan jets. They can turn it on and it emits red/orange light, mimicking the afterburner (re-heat in UK verbage) of a jet fighter.

I'm not sure where on the Ultimaker you could place that. However there are numerous fuse blocks/12v battery sources you could wire in.

I cannot help exactly, but it looks a bit like this one:

which seems to require 1.5W at 12V

You could put a resistor in series and try to wire back to the main 19V power supply

I connected a single LED through a resistor to the fan wires on the extruder head:

my setup only comes on when the fan is on, but it might not be enough to power your LED ring, you'll have to check the Ultimaker schematic.

Thanks, that's exactly my led ring. I try and not blow the electronics up
