[sdiy] AR Question

[William Berzinskas]

Just messing around with the attached circuit over here..   it seems to give a more desirable range when i present 12v on the gate..   how can i mod this to accept 5v?  
i've tried a few experiments with a transistor (which i'm almost positive is the answer), but i don't know enough about them to make it work..  anyone, anyone?
