ESP32-C5 ~$10
ESP32-P4 ~$5
Display ~$10
Case is maybe 90 cents (let's round to $1) if you print out of ABS.
The rest of the components? Let's say another $15 worst case.
~$41 or around that much? Sure, but definitely not ~$193.
I don't get why the maker market complains so much about the idea of businesses selling products at a healthy markup. Just because you know how the sausage was made doesn't mean that the logic of operating a business is any different to how it works in the consumer world.
If you're skilled and motivated enough to make it yourself, you might save some money. You'd loose a lot of time though and that's worth something too (perhaps a lot more).
The kickstarter was successfully funded, yielding in over $3.3M. The device back then was $149 at 20% off, with $169 being the full price. That's still not $193.
Again, this is just my personal opinion, but even taking everything into account and factoring in a nice profit margin, being OVER $100 is very, very hard to justify.
