Quick update on the new stereo amp. Apparently I blew it up again. This one was easier to take apart so I took the top off and got a peak underneath but nothing out of the ordinary. I checked the fuse with the multimeter, inspected the capacitors individually with a magnifying glass. But I couldn't find any visible damage. It didn't make a sound, or smell like the Insignia when I blew that one up. I did manage to demo the new stereo amp and demonstrate that any stereo amp will work with this Rodin Coil system. I did manage to get the neodymium sphere to spin this morning WITHOUT spinning it up by hand. Using a sine wave and pushing the output of the tone gen all the way to the Right channel(Right goes to coil/left goes to reference circuit). This reduces the power to the left channel/reference circuit but allows more power for the right? Maybe. However, I need to discuss with the team the best route to go forward. There is something I must do to the system to prevent the extra energy from going back into the stereo and blowing it up. More information will be forthcoming but you can check out my new 8 hour long demo stream here:
Hi Ben, sorry to hear that your new stereo amplifier is already damaged! I am not sure which setup you are looking to use and saying that for my home made PEMF device, I purchased the below devices and hooked up my coil to it. The PWM module will not give you 7.83Hz either 7Hz or 8 Hz up to 1KHz, so not sure if it would be good enough for your tests:
AC 110V/220V to DC 12V 24V 48V 60V 20-100A 1200W Switching Power Supply Adapter
LCD Display Adjustable PWM Pulse Signal Generator Frequency Duty Cycle Module
