In 1919, astronomers performed an experiment during a solar eclipse, attempting to measure the deflection of stars near the sun, in order to verify Einstein’s theory of general relativity.  The experiment was very difficult and the results were marginal, but the success made Albert Einstein famous around the world.  Astronomers last repeated the experiment in 1973, achieving an error of 11%.  On August 21, 2017, using amateur equipment and modern technology, I plan to repeat the experiment and achieve a 1% error.  The best available star catalog will be used for star positions.  Corrections for optical distortion and atmospheric refraction are better than 0.01 arcsec.  During totality, I expect 7 or 8 measurable stars down to magnitude 9.5, based on analysis of previous eclipse measurements taken by amateurs.  Reference images, taken near the sun during totality, will be used for precise calibration.  Preliminary test runs performed during twilight in April 2017 accurately simulated the sky con­ditions during totality, providing an accurate estimate of the final uncertainty.
