Hey guys and gals, I am trying to build a cylinder head that operates using electronic solenoids to open the intake valves. This is strictly experimental and need to construct a circuit that will give me these results...
cycle 1-10 Hz
supply higher amperage 1-3A? to pull in a couple hundred grams of steel.
control pulse width
I have constructed a signal generator from a 555 timer and am currently having issues testing it on an LED, but it simply does not supply enough current to operate the solenoid in the conditions needed.
I put together the circuit below w/ a 10uF cap
**broken link removed**
Im not a complete electronic noob, but I need help/suggestions on how to build a higher amperage circuit that incorporates a signal generator, or suggestions on how to use the 555 timer for this.
