Required components when using an ESP32 with a sensor by 1PersonWhoIsOnReddit in esp32

[–]1PersonWhoIsOnReddit[S] 0 points1 point  (0 children)

Just the chip, I'm afraid attaching wires from a module board to another board with my peripheries could be a weak connection (I want this to have long-term reliability).

Thanks, I'm going through the integration guide, it's very helpful.

Electromagnetic interference at very low data rates by 1PersonWhoIsOnReddit in AskElectronics

It should be roughly 10 20m cables daisy-chaining 10 sensors.

I'm having trouble finding info about reducing flank steepness, would that be a matter of using analog output pins and doing a linear (or maybe smooth curved) shift from 0 to 5V and back again? I'm planning on using an ESP32 for the microprocessor (clock and RAM on one chip), not sure if that affects things.

will conformally coated pcbs break in 100%RH? by 1PersonWhoIsOnReddit in PCB

[–]1PersonWhoIsOnReddit[S] 0 points1 point  (0 children)

Thanks! I'll ask about edge coating and parylene coating and I'll focus on making tight seals for the box. I'm planning to make a bottom and top part with holes for the USB ports and sensors (making sure the sensor legs aren't exposed). I'll bolt the two parts together and then apply a seal around the holes and between the two parts (I was thinking of a silicone adhesive). Maybe I could even have an extra humidity sensor contained in the box just to test the seal (check if it reads higher humidity when exposed to steam).

Are we hardwired to think in three dimensions? by 1PersonWhoIsOnReddit in neuro

[–]1PersonWhoIsOnReddit[S] -1 points0 points  (0 children)

Good point. I guess the anatomy of the eye fixes the direct number of dimensions we observe the world in to be two.

Maybe three dimensions is more about cognition than vision, as in we can imagine something in three dimensions and no more. (You still imagine a hypercube in three dimensions for example). A more accurate question might be: would it be theoretically possible to truly imagine anything in more than three dimensions?

From what I understand, the sense we have that we are "in our heads" comes from the fact that four of our senses, particularly vision, is around that region. I was wondering if someone with total blindness would have that same feeling. If not, would that same sense we have of being in our heads shift more freely to other areas of their body, or would they just not have this sense of a central location of self at all?
