Five Below Greentech electronics toy

Five Below is a store where all goods are $5 or less.  This toy

is $5 but you have to buy two AA batteries.  I bought one to look inside and here is what I found.

Nice little gizmo for $5 but would be more of an educational toy if there was an explanation of the circuit.
At least the kit is a starting point for an inquisitive child.

Arduino 101

This is the official successor to the Arduino Uno, the Arduino 101.  Here's the story on the official arduino site.  I assume that eventually it will be available in stores like SparkFun, MicroCenter and Adafruit.

Possible successor to the Arduino Uno

SAMD21 Dev Board  This board by SparkFun sounds like it could be a replacement for the Arduino Uno, low power but more powerful.
