This is quite a project! I love it!
I actually happen to have quite a few of those parts lying around (minus RFID/LCD) that I was going to use for one of Mikal Hart’s puzzles. Now that I’ve seen this, I think I’m going to combine the two.
I think it’s time for me to buy some more parts :D
Isn’t the LED forward voltage supposed to be the same as the backlight supply voltage? They’re different.
And how would you drive the backlight with 150mA?
To clarify, charging with a MAX1811 at 500mA won’t cause a LiPo fire.
And if I put this battery in a charge sack, and it did explode, will the fumes ignite a wooden box? (I’m thinking yes)
Just wondering, have any of these ever gone up in flames (LiPo fire)? While I’m fine using them in my own projects, putting one in a reverse geocache box makes me wary – I don’t want someone’s house going up in flames!

A lot of stuff that you do with parts from SparkFun involves knowing at least a bit of electronics.
And I believe the credit can’t go below 0, it’s just if you get some questions right that your credit decreases.
It’s actually a great idea, but there will always be people who don’t want to put in the work.

Damn, class starts at 8:55am MST for me so looks like I’m going to miss out on Free Day again.
No chance for a weekend Free Day? So that students can also have a shot?

How clicky are these switches? What kind of tactile feedback is there?

To clarify, VCC is tied directly to 5V from the USB port, correct?
And please add a 5V jumper/switch!
