What courses teach how to design things like that?
What about the battery part of the LilyTiny? Can it work with one CR2032? will the neopixels work with it?
It was really fun analyzing the schematic and understand how it works! (i'm new to "analog" electronics).I can't completly figure out how the off voltage is calculated. is it specific for the need voltage/current of the used transistors? why did you choose to add diodes before Q2 to change it, and how did you calculate the approximate new voltages?
Isn't it a bad practice to put tension on your solder?In every video I've seen about how to cut the leads, they say don't cut the solder, only the wire, otherwise it could break in the long run.
