I'm not sure exactly how many lights you are looking for, or the exact effect you are trying to create, but you may be able to get what you want using individual LEDs:
These have a diameter of 5mm, so the nose is able to fit snugly into an antistud. I've used them successfully in Technic holes and Erling bricks. The main advantage here is that you can ...
I have also little soldering experience, but I managed to create custom extension cables:
First: open the cover with a small screw driver:
Remove the PCB by lifting the small notch to open the light block
Then you drill a small hole into the opposite side of the metal plates, insert a small 2-wire cable (~0,25mm) and solder it to the PCB.
The outer ring is ...
BrickStuff is very high quality, I have used them many times. They are US based, make all their light kits with thought and care, and stand behind their products. I especially like that their lights can be controlled for various light-effects and intensities. Flickering soft lights for candles and fireplaces, bright pulsating lights for emergency vehicles, ...
Ultra-violet radiation is emitted primarily by sunlight, mercury lamps, black lights.
LEDs emitting visible light will not produce a significant amount of UV radiation required to discolour LEGO bricks. However, LEDs can be manufactured to emit UV light,
Unfortunately after attacking this piece from every angle with some plastic opening tools, I'm quite certain there is no non-destructive way to open this piece.
I tried slipping a spudger in every seam where the plastic joins and was unable to find anywhere I could get any leverage, or even push it in more than a few millimeters.
Even the jaw piece is held ...
With only using existing non-modified LEGO parts a mechanical solution with a servo motor, two polarization switches and cluch gears is thinkable, but this is all really cumbersome...
It's a bit ironic really, there's a bit of (trivial) circuitry in the 2x2 black brick before the wires of the LED lights split that causes the LEDs to work no-matter the ...
The color of the LED on the LEGO EV3 Color Sensor depends on which mode it is in.
From the EV3 help file:
When the Color Sensor is in Color mode, red, green, and blue LED lights on the front of the sensor will turn on.
REFLECTED LIGHT INTENSITY MODE
When the Color Sensor is in Reflected Light Intensity mode, a red ...
Looks like I solved my problem myself.
Here's what I did:
I exported the Lego model as Collada (.dae), and imported it in Blender. Selected the material and changed Diffuse BSDF (Maybe changed for you) to Translucent BSDF (for cycles only), selected Volume as Emission and rendered.
