some more context because I'll probably pin it on my profile:
This is a pcb that's designed to go in the cap (on the outside) of a Dopper water bottle. It keeps track of your water consumption, by counting up whenever you click the button (when you finish your 500ml)
attached image is the backside of this same pcb, which has all the smarts. The black ic on top is a 74HC4017D decade counter. Everytime the button on the front gets pressed, the number stored gets incremented, and for a few seconds power is supplied to the led segment that's linked to that number. When the counter reaches 5 it resets to 0.
well.. couldn't help myself making some last minute changes. With fresh eyes I realized it was possible to do the routing better, removing the need for the 3 0hm bridging resistors (marked red in picture 1).
also added a link to tilde.industries, product name, and moved a few other things around to make it nicer to solder
Smol server part of the pixie.town infrastructure. Registration is approval-based, and will probably only accept people I know elsewhere or with good motivation.
