Today in neat electro-optical detectors: hybrid photodiodes!
Photocathode on one end, photodiode on the other, electrodes in between, pump to high vacuum. Photocathode emits electrons, which are accelerated and slam into the photodiode generating a "photocurrent".

A Solar-Only, Battery-Free Device That Harvests Energy from a BPW34 Photodiode
A Solar-Only, Battery-Free Device That Harvests Energy from a BPW34 Photodiode
Normally when you think solar projects, you think of big photovoltaic cells. But a photodiode is just an inefficient, and usually much smaller, PV cell. Since [Pocket Concepts]’s Solar_nRF has …read more

Heres the output of the photodiode when flicking a flash light to it. You can see it jumps from 5V to 0V when it sees enough light.

Not even the Famicom revolver has this much mechanical detail. I'll look at making a batch sometime if folk are interested. I want to incorporate a potentiometer to fine tune the photodiode so games could be played on LCD sets (though it's not very reliable compared to playing on CRTs.)

Photodiode output is much weaker than should be at 3PM. Exterior lights have woken early in razorwire-fenced parking of my building, a fact I scraped watching an encrypted surveillance camera feed from a neighboring lot.
Our external feeds would of course not be subject to SSL flaws we put there.

10. The boards’ manufactures obscured the part numbers but we can still surmise these. These boards have a bidirectional (BiDi) transceiver that contains a laser to transmit and a photodiode to receive. The transmit board has an A-to-D to capture the analogue video signal.

Got the amplified photodiode out tonight to try and see if it would pick up the fireworks and worked! Didn't expect them to sound so interesting!
