Only a nerd will be amused by this: So I buy my kid a Tiny Circuits kit to help him learn the basics of electronics and circuit design:

Of course, the first thing I need to do is add some AAA batteries to it… so I grab the battery case and look at the schematic printed on the front of it…

Really? I doubt it… let’s find out!

As I suspected!

Okay, so then I decide to build one of the circuits… and they missed another opportunity for teaching!

Here is their dice game, take note of how they count to 6 with the three lights:

They could have just as easily used Binary, and taken a minute to teach how to count in binary!

100 = 1
010 = 2
110 = 3
001 = 4
101 = 5
011 = 6

And they could have continued if they wanted showing that:

000 = 0
and:
111 = 7

So with three LED’s (3 Bits) we can show eight different combinations.
