@fosdem ok so PCB making with sensors sourcing and assembly comes to 33 EUR per unit (if I do a big order). Sourcing USB power from mains socket is more expensive than I expected, so I am calling for devroom and stand owners to adopt a sensor, i.e. to look after it and make sure it's fed organic local-grown electricity (USB-C 5v, no PD should be needed).
@RichiHRichard "RichiH" Hartmann @fosdem my letters to misc #FOSDEM maillists seem to have been held - I guess moderation or bugs. Zero responses in any case, which is unfortunate. I take it as a sign to make the smallest possible batch, 10 units. I just want to minimize the hole in my pocket in absence of any expression of interest from others.
Order made. Devices should be in my hands towards the last week before FOSDEM. I will set up monitoring and contact schedule app devs to try integrate this feature.
