As you can tell from the fact that it has no base, this is a work in progress.
However, for those of you who want a half-finished mushroom lamp, here ya go.
Remixed from Fido's Ghostly Glow LED Mushroom, (thanks Fido), I just put a bunch of them together, being careful to avoid the mushroom caps hitting each other. I have it spaced out quite nicely, so that when you secure the tops on, they have a nice staggered look.
I also noticed that someone else made a three-mushroom variant of the same project, huzzah!
The wires are kinda a pain to route through the holes, I recommend attaching a resistor down below the pipes begin, in the base. The clearance in those holes is pretty tight. Yikes that sounded wrong.
