So, I got the first of my digikey orders in today.
This included my analog accelerometer, the compass chip, and the buzzer among other things
Look at all these paaaarts!

The LED that burns twice as bright burns half as long
I was doing a little napkin-math to see what my power/space constraints would be.
Reading the specs of the CR2032 battery, I found that the maximum rated continuous current is 1mA and the max pulse current is 10mA. Typical full-size LEDs take something like 20mA. But even if the LEDs only took 5mA, that’s too much when you factor in all the other crap on the watch.
I’m not too worried about it at the moment though. I’m assuming I can push the battery a little because I won’t be drawing boatloads of current out of it continuously. I took the back off my binary watch and found that its massively bright bank of LEDs runs off a CR2032 and it might have up to 8 LEDs on at a time.
