Hey Jude

Ever wanted to explore thousands of the world's radio stations, in seconds, simply by spinning a globe? I created the DesignSpark Radio Globe to mark the 10th Birthday of DesignSpark and the launch of DesignSpark Mechanical v5.0.

I'm a Product Design Engineer, currently living in the UK. I have been fortunate to have lived, studied and worked in Hong Kong, Norway and California. I believe physical models help people to communicate, develop and test their ideas. I give workshops and have been creating tutorials showing how to work with simple materials to create functional objects - either for professional work or for just for fun!

I think there may be a few too many "RS PRO, M4 Brass Threaded Insert diameter 5.6mm Depth 7.95mm" in the parts list. Its states 100.

@philipsg So the M4s are optional, but the M3 type are pretty essential. It's slightly problematic that you can only order in pk of 100, but then I think they are darn useful things to have in your workshop ;o) Do check out the full guide, which gets into more specifics... https://www.instructables.com/id/RadioGlobe-Spin-to-Search-Over-Web-Radio-2000-Stat/ Thanks for the note tho =)
