I have finished detailing the top surface and built a communications dish.
Just for a change I truncated the dish from the full circle. It is made as per usual from a small LED push light dome. The support arms are from a broken transformers toy. The signal sensor on the dish is also a transformers part.
The green sensor dome is from a baby's toy.
The black shape with the slot in the top is from the cover of the laser head from inside a CD Walkman.
The other black shape I think was out of a ink jet printer.
I also made an opening hatch which was pretty pointless as there is no hole underneath. I'll probably end up gluing it shut. The hatch dome was a cut down dial from an old washing machine.
The rest is the usual assortment of kit parts and styrene sheet panels.
I also added some half round ABS extrusions around the purple acrylic pot halves in the valleys. This gives the subtle impression of an underlying inflated shape which I quite like.
Thanks for looking.
