@blaukon said in 2nd mirror! 175x45cm:

Mailbox (unfinished)

Sender - RYLR896+Arduino Nano
=> motionsensor for new mail
=> reedsensor for picking up mail
=> energy: “simple” usb powerbank with rechargeable AA batteries (does not shut off due to low power consumption)

Receiver - RYLR986+ESP8266
=> energy via USB Port rasberry pi

Can you please share more build details for this?
I would love to be able to have such thing myself, but I have no clue what to do with these parts! :face_with_tears_of_joy:

@justbob
It’s currently laying on my desk :-(
Couldn’t find a proper way to detect new mail properly yet.

[banbutcher]

have you a network speed checker running? that could account for the 500mb your using?

[blaukon]

@banbutcher yes, used screen and nethogs and tried lowering the refresh-rates of some modules and the data-usage dropped quickly

That’s a really great build! Congrats!
I like the (physical) mail notification and pickup idea very much. So please keep us in the loop with how it works out,
