Induction powered LED lit engagement ring
As neither a mechanic nor a photographer, thank you for the clear explanation.   I learned a lot and was, at the same time, smiling... was your (now) fiance berating you during the development process for spending all of your time in the workshop/start up office or did she know what she is getting in to.  Let's be honest, with your skill level on fabrication combined with curiosity I don't suppose this is the last project...<p>Meanwhile a (long and rambling) question.  With some friends we bought a friend a quality lathe for their birthday.  I was involved in sneaking it in to their basement, and holy <i></i>* was that thing heavy! During the write up you make use of various tools - some seem appear to be professional level, base mounted etc, then at the end you mention the dremel... right place/right time... does it do the job you expect of it?<p>As an Englishman that moved to the US, 15 years later I am still trying to decipher infomercials, advertisements, brand names & US/Europe preconceptions, all comment welcome!
