I'm not sure of the protocol for this wiki so if this is the wrong place to ask this question please let me know.
I've spent most of my career in automotive and aero fuel injection and have a fair amount of expertise in driving solenoids and other e-m actuators at fairly high speed (above 1kHz for some).
Is there any interest in showing ways to extract max performance by reducing opening/closing times? If so, I'm willing to write it up and can provide some example circuitry with analytical and empirical analysis. I have tons of schematics/photos/scope traces etc. Every drive circuit I've ever designed was meant to be triggered with TTL so it's all adaptable to Arduino.
Thanks for any feedback.
