Aaron's Test Set-up
Hi Folks,
I just spent the afternoon with Aaron getting his test set-up calibrated. He'll be posting a simple 555 timer circuit we developed that can produce the right frequency and duty-cycle drive for the MOSFET. We were able to set the ON TIME of the drive circuit to 16 microseconds and the wavelength to about 416 microseconds which gives a 2.4Khz square wave with a 3.7% duty-cycle.
Considering that we don't know anything and only have dirt and twigs to work with, it wasn't that hard.
Aaron has the right MOSFET and we are looking for the closest match we can get for the inductive resistor. The rest is pretty straight forward. It will certainly not take us 400 posts to convince people how difficult it is, since we got everything designed, built and calibrated in less than 4 hours of real, work.
Aaron has pictures and schematics that he will post. There are no test results yet, since we are just setting things up right now.
This is a breeze, guys, so don't be distracted by the Goof-Balls and Nay-Sayers.
