Progress update on my pendulum-based test. While I cannot yet report on whether EmDrive is producing thrust or not (congrats to Shell!), I can at least report that a 50 Ohm dummy RF load is definitely not producing any. This is a good solid start; rumor has it that the only thing one needs to change now in order to obtain thrust is to use a frustum-shaped cavity instead of a dummy load We shall see.Heres the completed test pendulum with all the components illustrated. The suspended platform is self-contained with a power source, RF generator, RF pre-amp, RF power amp and even a simple RF power meter for visual conformation on whether the forward RF power is as expected. There is also a virtual wire link to the base via a pair of XBee modules to control RF power on and off. The base has a high voltage power supply to energize electrostatic plates used as a source of controlled force to the pendulum. It also has a laser position sensor and a DAQ board.Heres a 30 s idle run of the system. (This setup turned out to be sensitive not just to my HVAC furnace, but also to the fridge being on where the fridge is ~20 ft away on a concrete garage floor!). Still, the run looks pretty stable. My own DAQ software is detecting min and max points (with some applied hysteresis) and drawing a line via computed mid-points.Heres the actual test run. 50 s total: 10 s idle, 10 s RF power on, 10 s idle, 10 s high voltage on, 10 s idle:This is a zoom-in on the RF on period:This is a zoom-in on the HV on period:From this I would infer no force being produced during the RF on cycle, while an easily recognized force can be seen during the HV cycle. Now I just need to replace the RF dummy load with a matched frustum cavity and there should be thrust during the RF cycle, right?I will be starting with an empty cavity at ~2.35 GHz. Assuming no thrust, will then add some dielectric to it. If there is still no thrust observed then I will need to invest in another RF amplifier to move to ~1.8 GHz range and to replicate the EW design.Happy Holidays!P.S. This setup is capable of computer-assisted electrostatic damping. So far this turned out to be the most difficult to implement (and, frankly, a mostly useless) but a pretty cool feature. Numerically solving pendulum differential equations on the fly to arrive at a perfect damping pulse position and duration (there must be an easier way to do this
