DICE - a tiny, rigid and superfast 3D-printer
Great work! Merry Christmas indeed. :-)Hmm, maybe some teeny tiny LED gifts?
See: http://www.instructables.com/id/Star-Map/step16/Se...I used the transistor for brightness control - when the amount of current flowing through the gate is limited, the amount of current flowing through the main part of the transistor is limited as well.Limiting the current means that the LEDs run at a lower brightness than (for my LEDs) "blinding".You could build a test circuit similar to the one in that step, to demonstrate the concept for yourself.
Awesome! :-)I hope the three sizes of fibres works well for you. If you can, best to terminate each fibre size to a different light source. That way the relative brightnesses can be adjusted to what you want.
