felezjoo PI(the best pulse induction metal detector that I made until now)

[lc516]

change ic357

do you suspect it's shoddy?
Thanks for the advice!

[basellafe]

maybe its a fake but you should give a try

[lc516]

YES, I'll do it.

Thanks!

What if i use 0.5 watt 390 ohm 1% resistor for the damping ,is there will any problem? Cant find 1% for higher watt.

You can build the resistor buy parallel and series resistors to get the needed wattage

i need hex files but it shouldn't counter. if you have hex files can u send me ?

Good idea, never flash in my mind . Thanks

Some of the 1/4 and 1/2 watt resistors have a 250 volt working voltage. Would it be a good idea to series 2 or 3 resistors to get the correct ohms and watts when the peak voltage is over 250 volts or is the high voltage spike so short that it doesn't matter?

Felezjoo v3_05 hex code error ...Do you have a running v3_05 hex

[cakalist]

best hex kodu version ?

100 ohm resistor to connect 180 ohm series

Yes its always a good idea to run components within specs so with a typical PI flyback voltage of about ~400 volts 2 or more in series will over come the break down problem,
I find that excessive heat kills resistors , at least with my projects, so building for power so they don't run too hot is also important .

Hi fellows. You could teach how to program atmega with arduino.Thanks
