After posting the photo of the lit staff we made I've been asked a bunch of questions regarding lighting things up.
Let me just say, Mick did all the lighting stuff...I did the easy part and made the staff.
Mick is an electronics engineer who makes life support equiptment (ventilators) so lighting a staff, or any miniature, is simple to him. He speaks in the tongues of strange languages such as biology, physics and chemistry...all completely over my head.
He is working like a madman at the moment on a new ventilator they are about to launch but, once he has figured out all the problems and it has all quietened down, I'll ask him if he will do a quick tutorial.
In the meantime, maybe you can figure it out from this photograph.
