My biggest 3D print so far (13.5hrs)
It's a decoration piece to create nice light and shadow effects.
I'll use it to experiment with LEDs.
I combined 2 scanner RGB leds and programmed some Arduino loops.
Together they form a police strobe light.
No real flash patterns are used here. It's just a demo.
A recycled scanner rgb led lamp from a broken HP all in one printer, controlled by a Arduino Nano.
I ordered this DIY LED lamp kit from a Chinese web store. They only cost 1 - 1.5 €, it depends a bit on the vendor.
It's a nice little kit to build on a free evening, seems to be of reasonable quality, and is useful after building.
This lamp was advertised as a 2.4W lamp, that does not seem much, but for a desk lamp it's more than enough.
And also important, the light color is good, not too yellow or white.
