    [SOLVED] Voltage drop when starting car

    Using a diode worked, but to get the capacitance is the problem, 5V 1A took me over 3000uF cap and couldnt keep the board on

    [SOLVED] Voltage drop when starting car

    If used a NiMH battery, do I need to make a charge controller? or I can just use the car's controller? My problem for capacitor is the current I need, the cap will need to be very big for just a few seconds

    Help with track width

    Hi, I made the board with no mask.. I don't know if this post should continue here. But I have another doubt. I made a board really simple with this TRIAC and I wanted to add an current sensor for me to monitor and turn off the TRIAC if I get some overload. The problem is I cant find any...

    Help with track width

    Thank-you for the answers. I made mistake, my circuit is 220V 15A max, so I will use an BTA26 for ensurance. I'm thinking to use 2 OZ copper board with track width of 86 mils, accourding to the calculator it works fine.

    Help me set AN5 as analog in PIC16f877a

    Re: Help with Pic16f877a I made some changes to set the VREF+, so I'm using now the AN0 as input ADCON0 = 0b10000001; ADCON1 = 0b10000101; How can I read the result? Thank-you
