Nice. But you can not turn it fully on or off.

It does have a spst switch to turn it off.

No point in having a transistor to drive 12mA when 555 is good for up to 200mA resistive output. Just drive the load from 555 output.

The signal should just be fully on when the potmeter is too.

No imagination for 555, the sun rises and i haven't slept yet. Opamp w/sawtooth. http://everycircuit.com/circuit/5260740113203200
