I am new to electronics and am trying to build a fun project that needs a solenoid strong enough to push/pull the latch open of a masterlock (thats open or combo has already been entered) Im not sure how strong my solenoid would need to be or what I should use for a power source. Any tips or place to start would be great!
I have found this one: http://www.digikey.com/product-detail/en/F0462A/527-1021-ND/668306 is it enough? overkill? and what kind of power supply would I need?
