PiTone-v2-by-Eddy71 Has anyone on here built this ?

[sbalio1]

hi friends can ennyone here help me i just use pic16f1824 it seem like pic16f1823 the problem is when led light just one led blinking with sound . what is the problem help . if ennyone can modified hex for pic16f1824 help me friends. [email protected]

Use extra flux.

faraday tape, I bought a 40mm wide tape thinking I could cut it into the width best suited to wind over a coil.

so yes with some care you can solder to it, first I soldered a bit of used solder wick, thinking it might be more gentle (Its plastic ?), then I just soldered a wire direct.
This tape has a conductive glue so just over winding it makes a connection on both sides.
But yes you can melt the tape with a soldering iron

Microchip and many, many PIC's so not likely two of us pick the same one.

This is true but thanks for the reply, now looking at your links

am I really the only one on here with an interest in the PiTone-v2-by-Eddy71 has anyone got a pic16f1823 or pic16lf1823 ? on a detector am a little surprised lol

Not the PICF1823 but use the PICF88 and the PICF1501 in my HH2 PI detector.

The source code for both are posted in the thread.
The 16F88 does all the PI timing including reading the adjustment Pot setting (Pots into PIC ADC). The PICF1501 does the audio threshold and tone generation.

Also, the pin pointer I built uses a PIC1840. This is a design by Teemo in this thread:

Hi David_1

This video is excellent!!! It helps a lot to find easy the correct damping resistor for your DIY detector coil without experimenting much.
Thanks to Surfdetector (for making the video) and David_1 to highlight this to us.

surfdetector so his video needs more views

[David_1]

so while waiting for them to come back from newyear... I guess they can have holidays too been messing with the Pic16lf1823 I can now get it to dump serial comms @ 9600 out of where the motor should be.. planning to output data so I can see it on screen while trying to setup detector..

If you are interested in a more complete description, here I argue with the author of the idea of "Pirate" and explain how the details on the indicated node of the circuit work:

Hi Eddy71,

thanks for the link. I had a look at it. Now it is more clear how it works. Thanks again.

Hi Eddy71,

thanks for the info. I must have overlooked this.

so its still work in progress, but I ordered them so lets wait and see

Hi David,

here some improvement ideas for your PCB.
1) Some mounting holes would be nice to have. Or do you fix the PCB with "Siemens air hooks" to the enclosure?
2) What about a heatsink for the MOS-Fett?
3) The PCB size and orientation of components. What enclosure are you intent to use? Actually before I make a new PCB I think first about which enclosure I want to use and where are my controlls located. Specially potis which needs adustments. The poti you choosed is okay but is it also accessable if the PCB is mounted with in the enclosure?

Here soome more ideas to improve the circuit board design...
4) A text legend of what detector it is and about the PCB version is always nice to have.
5) Mounting holes should fit the components. In your PCB design the mounting hole of the Mos-Fet looks a bit off center.
6) Tracks and other components are a bit to close to the mounting hole of the Mos-Fet.
7) Tracks should not run under the Mos-Fet. At least not on the site where the Mos-Fet is mounted.

Thanks for the sound advice, normally I would never draw a pcb without first having an enclosure, but I really don't know where this is going to end up... maybe the bin LOL
will the mosfet get that hot ? I have never made a metal detector just been around electronics all my life.
my main goal was to understand the code, that has been reversed Eddy knows this I have sent him most of what I have done. I am not trying to steal his work or pretended its mine.
I admire people willing to share their designs online, I see this whole thread as a way to understand how it works and maybe improve it
