10 Double Flash
Four gates can be used to set up two independent flash circuits at
once. In theory, they are supposed to work at the same frequency. In
practice, however, low component tolerances cause the two circuits to
not work perfectly synchronously. If you touch one of the capacitors
with your finger, slight heating will cause slight reduction of capacity.
The corresponding flash then speeds up a little.
