Can anybody tell me how to use the sign output of the SCl007 on Carl Morelands circuit to luminate 2 led's to show which sensor is receiving a signal?
Also, it's a long shot, but I'll try, has anybody got a circuit diagram to connect the gradiometer to a PC?
Why do Speake & Co recommend a 20Mhz crystal, would it improve the sensitivity if I upped it from 16Mhz to 20Mhz?
Thanks
