Re: What can you do with a 74HC00?
Building a half-adder out of 7400 gates would be an excellent start.
Problem: People think computers are magic boxes that no human can understand - and therefore grow up believing everything the computer tells them.
Solution: teach people how computers work at a basic level
Teaching people to click on icons in word to make a web page doesn't do anything to change the "magic box" picture. Even typing python into a RPi after watching pages of incomprehensible Matrix-like Kernel boot messages doesn't really teach anyone that a computer really is a very simple idea.
Arduino is a great idea, it would have been nice if this thing was an arduino clone so it could use the same sketch software and be a stepping stone to arduino projects. (perhaps it does haven't seen any details)
