## How I feel about the end product ## How I feel about the end product
I think the card looks good. I like how the buttons feel, how the screen looks, and the overall design. I do wish the battery wasn't so chunky, but alas- NiMH AAAs are litteraly the cheapest rechargable batteries I could find (at sufficient power density). It would also be nice if I could have them assembled for me, so I could hand them out more freely. The border tracing algorithm worked pretty well, but wasn't quite fast enough when zoomed in, or where there's a lot of sharp edges. One of those locations is, unfortunately, where card starts on boot- a location I choose becuase it looks very good. If I were to redesign this, I'd go with a cheaper and higher spec MCU, preferebly one with an FPU. I chose an STM32 because I had a dev board, but they're really too expensive and low spec for a project such as this; I don't need to pay for automotive grade hardware. I think the card looks good.

I also swapped the "charing" and "full" text. I'm not fixing it. I also swapped the "charging" and "full" text. I'm not fixing it.
