Perimeter receiver program

[nero76]

And how does the signal look like if you switch off all filters (Filter=Off, Math=Off)?

It looks like your sender isn't working - Is your motor driver getting warm (or even hot)? If not, it's not working...

Hi,

It looklikes as below:
Inside:

Outside:

Quite different from your reference. Moreover, these measurements were done when I was very close to the wire. If I go more than 1 cm, there is a flat signal. The motor driver is burning, I can not stand for a long time but it seems normal, right?

Is there some benchmark voltages to have at certain specific points?

Thanks,

Adrien

Hello Adrien,

Your signal looks quite good (I did show you the 'ideal' signal as it was generated by the software), not the received signal.

However, I found an issue with Google Chrome Browser (Matched filter doesn't work there - I did use Firefox). I'll try to fix that.

Yes, the driver can get hot, so it's a good idea to add some bigger heat sink. Or using a longer perimeter wire (unrolled in the lawn of course, not rolled-up).

Regards,
Alexander

Addendum:

Here's the (ideal) sender signal (as it is generated by the sender): http://wiki.ardumower.de/images/a/ad/Ardumower_web_oscilloscope_time_signal.jpg
And here's the received sender signal (as it is received by the coil): http://wiki.ardumower.de/images/1/17/Ardumower_web_oscilloscope_time_signal_received.jpg
Although it may look different, both signals describe the same information (if you quickly switch between them you can see it...)
