Here's the last project I'm working on at the moment: DIY Blimp.
Total cost so far, less than 20.00$.
1x 3" x 3' PVC pipe. (can make 2 with it) = 6.95$
1x Mic holder (basic one) = 2.95$
4x "O-Rings" = 0.25 x 4...1.00$
1x Plastic Mesh = 2.00$
Here's some pictures:
I'm still looking for some fur to put over that. Actually, I don't even think I'll need the mesh all over the blimp. With the shape of the PVC pipe, I think just the fur all over would be enough. I'll see. I still have to do proper tests.
I'll keep you updated.
