This page will collect any photos, plans, and instructions for do-it-yourselfers. Efforts with enough documentation will be provided their own pages.

  1. Mulletron's Build
  2. Kurt Zeller (@zellerium) and Brian Kraft from Cal Poly are starting a build as well, using a constant cross-section cavity containing a polymer dielectric.[1]
  3. @DIYFan - TBD
  4. @Notsosureofit is planning testing with a Gunn diode.[2]
  5. @TheTraveller[3]
  6. @Iulian Berca[4] - Fabricated a drive in May 2015 and was posting videos at his website. In Test 3 he reported a force measurement toward "the small end" and later a smaller measurement in the reverse orientation in test 3.1. As of 5/21/15 the magnitude and significance of these measurements were being debated on the NSF forum.
  7. @SeeShells plans to build a hexagonal frustum out of copper mesh. The small end plate will be adjustable via a stepper motor.[5]
  8. @R. W. Keyes / Andromeda Research - high power, 1-20KW magnetron, superconductor Magnesium diboride on silicon carbide, to start summer 2015
  9. @movax (Paul Kocyla) and Jo Hinchliffe[6] - Building the original 2.45 GHz thruster according to the Chinese paper and their own 24 GHz design simultaneously, with estimated completion date of July 2015. See Hackaday project for more details, as well as an interview with Paul.
  10. Dave (@rmfwguy) plans to use a wifi band exciter board as Rf source, wifi booster amp, copper mesh for the frustum body, and no dielectric in the frustum.[7]. Starting in July 2015, this will be live-streamed on Ustream.[8]
  11. @DrBagelBites posted on reddit that he was planning on starting a build.[9]
  12. @kml Testing a non-tapered rectangular waveguide with various dielectrics inserted at one end.[10]


If anyone is missing, please add them here.

Modelling

@phaseshift has built a SketchUp model[11] (File:EM Thruster.skp) of a frustum based on the estimated Shawyer Flight Thruster dimensions.

@TheTraveller constructed a spreadsheet to model thrust given various design parameters.[12] This model was built with some input from Roger Shawyer directly.
