  We consider the use of a single qutrit for random generation. This is
possible because single qutrits exhibit contextuality features. We aim to
optimize the entropy of the generated sequence. To do this, we do not rely on
the KCBS inequality but instead on the use of a specific state and a check for
fidelity. By the way, we show that this check can be considered as a variant of
the CHSH inequality applied to pairs of photons or spin-1/2 particles (qutrits
are often realized as a pair of indistinguishable qubits). The physical
realisation of this random generator should be eased by the fact it needs only
to implement spin operations and measurement, not general $\SU(3)$ qutrit
manipulations.
