I have started with Guénolé our first task : build an electrical prototype of the Plume.
First, we have selected the wire for the coils of the emitter. We plan to use a copper wire with a section of 0.08 mm².
I have estimated that at 5 meters we will have a magnetic field of 10^-10 T and a tension of 100 μV at the receiver coil.
Then we have studied the STEM System by Sixense. They leak some information about the product.
They use the same technology, a concentric 3-coil design.
They have a DSP that handles the processing of motion tracking position and orientation.
The device generates pulsed AC signals at frequencies of 30 kHz and it can works at 10^-7 T.
And the best for the end.
Now we are working on the receiver circuit. We have to amplifier and filter the signal.
