Ok done the magnet tests to find what affects the system and came to the conclusion that it was both magnetic and electric fields that affect the device. So, im pretty much done, because we cant find a proper equation that works so I will have to just go on experimental data and form my own equation.
Also spoke to Wilkinson and I need to put an FFT on my matlab software and have a look at what frequencies I am working with. That means creating some excecutable to use on the uni computer, since thats the best enviroment to work from.
This also means that I really have to push the box machining to get it done asap. I will finish the threshold detector later…
Finally I need some pictures of the experiments for the documentation. So I will bring my camera in tommorow.

Images of the different concepts. Please Click On each one to see a BIG picture!
Bear in mind that these are quick (30 minute) drawings, so the final site’s colour’s/layout/images will be better, but these are just for a general jist to find out what sort of website you want.
Cheers, Phil

New device reults taken x4
Old device results taken x2
New device from 5m, results show that it could go further with more gain.
The old device was from 3.5m was rubbush. The noise problem appeared on the first set of results.

Found a very simple range finder here. Fairly basic though. Would like to try and use my mega sensitive Inst Amp on it, or at least use one of the inferior inst amps. INA121 maybe…

Right, he loved the device, and I told him about the problems with the sound card. He said what I can do is to modulate the signal at a frequency that can be interpreted by the sound card.
He says I could use a 4066 chip which chops the signal into little bits at a frequency of say 4kHz. Check the schematic here.

Heres some inked ideas that Dr. Paulson helped with.
