Build a tesla coil

Posted on November 29, 2016 by robertwilkie

Nice build and I like how the author shows it working with a CFL bulb.  It would not be too much of a challenge to build this too. http://www.instructables.com/id/Make-a-Simple-Portable-Mini-Tesla-Coil/

Here is a simple build for a windmill

Posted on September 6, 2016 by robertwilkie

Simple build.  The author is a bit scary with power tools (way he handles them).  Apparently doesn’t have a tablesaw.  Or the homemade welder…. http://www.newphysicist.com/make-vertical-axis-wind-turbine/
