WFC. Simple LC + Gated pulses

[slinky]

I have been looking at WFC stuff for a while, I have been trying different circuits for running the LC and I think I have made a super simple method. I know that when simulating there can be components beyond realistic values. So I'm looking for any suggestions for improvement.
