Hi everyone.
I am after some help on controlling a 24V solenoid valve in the creation of a firing mechanism for a paper rocket launcher for a school project, similar to this one https://bathastronomers.org.uk/2018/01/14/paper-rocket-launcher-how-to/
I have been reading up and believe that using an NE555 and MOSFET will possibly work (or use a relay?). I would like to ideally adjust the pulse time between say 0.01s and 0.1s (can I use a variable resistor for this?). I am happy to have 2 power supplies (12v for the circuit and 24v for the solenoid) unless there is an alternative?
The pulse will be triggered on the press of a button (I presume the circuit timing re-sets when the button is then released?).
Can someone pull together a circuit diagram for me at all and perhaps identify some of the main components required? There seem to be so many different ones available out there.
Based in the UK so RS components would be ideal.
Thanks so much, Graham
