    Newbie: Solenoid timer circuit

    Hello Again, Okay I have now built the circuit but I have run into some complications and need some troubleshooting advice if that's okay... I have double checked the connections and continuity and all seems fine but the circuit is not operating as expected. I get one of the following when...

    Awesome, thanks Minder. Does the rest of the circuit look acceptable do you think?

    Thanks Minder, So do you mean like this?

    Also not entirely sure what the 47k resistor is doing as copied it from the last circuit but it's now shorted out... :oops:

    Newbie: Solenoid timer circuit

    Okay. So here is my revised circuit. I am aiming to have the timer frequency at about 1.5Hz with a bit of fine tuning with the pot. Does this look sensible? I tried building the circuit using a Croc Clips demo but the 555 was blowing up under open circuit! so I gave up on that one. edit...

    Newbie: Solenoid timer circuit

    Hey, Thanks for all the replies. I see how a Darlington would make sense as you then have a common collector (is this right?). I made a hash guess as to how I could do this as I don't like going on forums and just asking "how do I do this?" as it seems a bit lazy and rude. I will draw...

    Newbie: Solenoid timer circuit

    Hello, I am fairly new to electronics and a first time poster so please be kind. I wish to create a circuit which sets off a row of solenoids one after the other. I have made an LED 555 timer circuit before but I understand that the voltages will be way too low for the solenoids or too high...
