Nice work !!

why dont you draw a simple "receiver" module running a photodetector backed with a tiny MCU, one RGB LED and a CR2032? All (I mean one "receiver" per drawer) would grab the LED data stream sent by the requester's LED, for each "receiver" to check if the message contains his ID in order to "output" or "no output" (that is the question, and that's what this project is all about!! :)

Kind of a upgradable, binary, Li-Fi powered, display.. As my best friend would say "only few line of code" huh

and I don't want to buy 120 coin cells

  Are you sure? yes | no

I'll probably mark them with a resistor or two and use some 4051 chips for muxing and scanning / reading the value.

I don't believe it works as a display (ahem, video) or at all (ahem, source).

  Are you sure? yes | no

davedarko wrote 09/21/2018 at 05:29 • point

I haven't started anything, indeed. The inside of the box seems to allow for too much bleeding as well. We'll see what I can do about it...

  Are you sure? yes | no

Maybe putting the leds in a short tube will allow them to "project" forward more.

Maybe build a PartKeepr plugin :D - https://www.partkeepr.org/

If that's an idiom, I don't think it's known in English

  Are you sure? yes | no

davedarko wrote 09/17/2018 at 07:37 • point

@PointyOintment there's a bunch of idioms that translate horribly (word by word), this one is one of them and was not chosen by accident ;)

It actually translates to: with time comes advice, iirc. There's also "live life in full trains" - which should actually be something like "go through live with big steps (?)" 

  Are you sure? yes | no

Nice idea. Of course, you could just number the boxes as well (box 1, drawer A1, A2,.. A5, B1, B2..., box 2...) and the webpage would show the box and drawer numbers, but this wouldn't be as fancy.

  Are you sure? yes | no

there are sooo many things I could and should do. But, I'll do it myyyyyyy wayyy *sinatraed*

  Are you sure? yes | no

davedarko wrote 09/16/2018 at 20:27 • point

actually it's all about them contest rules

  Are you sure? yes | no
