Hi all,
I’m a first year engineering student and I’m just trying to wet my feet in electronics builds. I am trying to build a pneumatic napkin launcher for a bit of fun with some of my friends and I just have a few questions so that I can build it.

I’m a first year engineering student and I’m just trying to wet my feet in electronics builds. I am trying to build a pneumatic napkin launcher for a bit of fun with some of my friends and I just have a few questions so that I can build it.
- The only solenoid valves I can find are 12v so how can I supply it with enough voltage from (preferably) a 9V smoke alarm battery?
- The Micro controller is to make sure that the solenoid only opens for a fixed amount of time, and the input dial is to experiment and set that variable. What components would you recommend purchasing for this?
- Given the low energies involved, are these components even required. (is there anyway of running everything through the micro controller to bypass the relay)
- If there’s anything else I need to consider please let me know.
