Fast, high current switching
While virtually any transistor optocoupler can be configured to work (PS2501 will work just fine, see: http://hobbybotics.com/projects/hobbybotics-optoisolated-relay-controller/ ), If you are going to source one specifically for this project, you might consider this: VO3150A. It is designed...- Fish4Fun

Fast, high current switching
A 5V turn on Mosfet like the IRLZ24 // IRLZ34 // IRLZ44 will provide an easy interface to your Arduino. In your diagram above, simply connect 1 side of the solenoid to +12V, move the mosfet drain to to the load side, the mosfet source to ground, eliminate R2 and choose a ~10ohm Resistor for the...- Fish4Fun

H-Bridge Circuit Design
I would like to build a 4 channel H-Bridge suitable for driving an inductive load (predominantly three-phase "BLDC" and steppers, but also for testing the reactive components of an SMPS) Rather than being a dedicated driver for any particular motor, I would like to build a "prototyping" driver...- Fish4Fun
