DIY Planetarium


This week I’ve made a portable planetarium dome using references and instructions from enthusiastic DIY dome builders who share their knowledge online. The dome is for a collaborative project with the IED Masters students from the Exploded Screen elective at Royal College of Art and the Planetarium at the Royal Observatory Greenwich. It is fifteen years since I first designed images in a planetarium but the fulldome projection space remains a joy, so creating this small hemisphere has been a pleasure.


Gore panels were cut to size using this calculator.

Fibreglass tent poles make the framework and despite a few nervous moments it fits together beautifully.


Hayden, Kelly and Yasmeen complete the structure with cable ties.


Setting up the projector, thanks to Kevin for his resourceful use of student lockers and to Rob, Ed and Tom from RMG for making it possible.
