Either can be made to work, but the lower diagram is conventional and is more efficient.

I connected it that way (the lower one)..

so why doesnt it work that way?

btw. the pulses are pretty quick.. about 100ms (maybe I'll try less, 50 or 10 ms).
does the power loss really matter when its so quick?

What value resistors are you using, and what is the resistance of L1?

I tried using values that range from 200~ohm to 10k ohm,  I will check the solenoid resistance soon.

thanks.

ok, it works, thanks guys,

A small note;
a DC solenoid might require 2 9v batteries, in paralleled connection. (I guess it is obvious but I lost alot of hours on that)
