    I found a cool pedal that im trying to make and i’m not sure if i should use 1/2 watt or 1/4 watt resistors.

    heres the link:

    also, it has two diodes on the little diagram thing and only one in the parts list.

    Thanks in advance :)

    1/ 4watt are common stompbox size. 1 watt are huge,

    As for the diodes, use the same two kinds.

    ok cool

    i actually think that they made a mistake and put in “D2” because if you click on the bottom to the finished one, theres a picture of the inside and there is nothing in the place where it says in the diagram to have a diode so i’ll just not put one in there. also it doesnt say anything about it on the actual schematic.

    so it really wouldnt matter if i used the 1/4 watt instead the 1/2 watt. would it make any difference to the sound at all or would it be the same?

    No it will be the same but you should use 1/4 watt.

    1/4 has a bit less noise, but it’s barely noticeable in simple circuits as most pedals. It will fit highly-populated PCBs with a bit more room, but are indeed a bit harder to work with.

    I only use 1/4-watters.

    Sorry i said you should use 1/2 watt, I was meant to say use 1/4 watt. sorry for the confusion.
    the tiny ones are 1/8 watt:

    mmmkay, thanks guys, i’ll use the 1/4 watt ones.

    and i’ve figured out that the “D2” is for the LED.
