    i am working on a 555 circuit trying to make an injector pulser. on my bread board the circuit works fine but when i transfer it to my protoboard it wont pulse correctly.
    i am very new to electronics and am learning very fast. i am using a diagrams from a led pulser and everything works great on the breadboard but when i transfer it I get various problams. can anyone help mi design a good circuit.

    Can you post clear photos of the topside and bottom of your board?

    What's the purpose of this "injector pulser"?

    Are you trying to inject pulses into a working digital circuit to see if the gate is responding to your pulses? If that's the case, you'll need a very different type of circuit.:D

    Hello,

    If you read the ToS, automitive modifications are not to be discussed over here.
    Is the injector to be used in an automobile?
