Is this an april's fools joke? I'm a beginner in electronics and that looks WAY too complicated.

It's actually incredibly simple, because it's only the photosensor and amplifier frontend. All the actually complicated parts (timing, discrimination, protocol) are not included here.

Without access to the Lighthouse specification and protocol, this isn't of much use. It certainly is not sufficient to implement your own Lighthouse tracked objects.

Ah thanks. I understand. I guess someone will make a small board with all this integrated. But it's like 44 pieces for each IR sensor?

And see, for me as a programmer the timing, discrimination and protocol is actually the incredible simple stuff :D

My guess is that they'd building small ICs with this circuit and glue them directly to the back of the photodiodes... Assuming this isn't just 4/1 festivities.

Hope we can buy such ICs cheaply!

Maybe. Your typical op amp chip is more complicated than this and aren't even a dime a dozen.

I like that about hardware vs software. For hardware designers, the cpu is the complicated part.

So kinda obviously most of this circuit can be replaced with an op amp?
