ABSTRACT
It’s almost time to “close” your fi rst hack, as they say in the O.R., but let’s look at a few fi nal modifi cations before Frank rises from the slab.
Beyond retuning the clock and fi nding some musically-viable almost-shorts, the most signifi cant change you can make to a toy is replacing the little speaker with a big one, thereby confi rming the Second Law of the Avant-Garde (introduced in chapter 7). A telephone tap coil resting on the little speaker is one approach, as discussed already. But if your circuit is never going to be played by saliva-drenched fi ngers it’s safe to try a wired connection directly to an amplifi er.
