That ball of C4 works the other way, too. Push a slight depression in it, cover the depression with a layer of mylar and aluminum foil, and zap the foil with a high amp charge, like from a capacitor. It's called a Slapper Detonator.

Cherry was famous for their fiber optic detonators. I wonder if that's what is missing.

Jeez, I didn't even think...... I'm an old man FF, sometimes it takes a little while for the noggin to kick in. Good point and well understood . Thanks, and Merry Christmas.

Never heard of it, but Geez Louise, we're talking some serious juice here....

The ballpark figures are 5 kilovolt and 1 microfarad rating for the capacitor, and the peak current required ranges between 500 and 1000 amperes.
