Default Re: Another "Pantry" Rig for the IC-allergic

Just one point, given that the supply is 12V, presumably the intention is to power it from a 'wall wart'.

It might be a bit more convenient if powered from a 9V PP3, or would it work down to 9V as it stands?

Or would some of the resistor values need to be reduced, (apart from the oscillator, served by the 78L05)?
