Testing of Clone PI AVR metal detector

Testing of Clone PI AVR metal detector

Some years ago a have started building Clone PI AVR. Made a PCB, soldered all the components and … and never found time to finish it until today. Well I haven’t finished it yet but at lest gave it a first test run. For the screen and buttons i have re-purposed some front panel of some old router. Now i see that i will have to put it in to another box for better mounting on the metal detector itself but this time it was good enough for test run. For Atmega programming I used Mini Pro TL866 programmer I have bought while ago – works like a charm. You can see some photos and video on work in progress.

    hello congrats, can you give more detail about tl866 programing avr, because i made the same proyect but program doesn´t work

    1. ask

      Hello. Make sure the fuse settings are correct for the avr (I will post my setting later). Also check that it is powered at all, with some multimeter on avr pins 7,8.

    2. ask

      Added some screenshots of MiniPro, hope that will help.

    Can you give me a look at the code

    What is the capacitance of the electrolytic capacitor that is connected to the pins
    7, 20 and 21 of the atmega 8 that on the R14 side?

    Hi my firnd
    Please email me if you have a deep metal detector circuit

  8. mehdi

    The type of element and the values of the element are determined in the circuit. Thank you very much

    how much range do we get using this circuit?
