The flashing is thanks to LEDs with a built-in, integrated flashing circuit and the nasty noise comes from a piezoelectric buzzer — both are available from electronics stores that sell ordinary LEDs.

Abstract: We present a capacitor-free, scalable CMOS neuron circuit that offers significant benefits, including a compact circuit area, low power consumption, adjustable firing threshold, and ...

If there’s one lesson to be learned from [Aled Cuda]’s pulsed laser driver, it’s that you can treat the current limits on electronic components as a suggestion if the current duration is measured ...
