“A simple gadget that translates binary numbers into hexadecimal.
The Hex Machine is a simple gadget with four buttons and a seven-segment display. The user may press the buttons in any combination, and the display outputs the corresponding hexadecimal digit.
Not very useful - just a fun little toy.
Note: Be sure to check out the code! It’s a nice demonstration of how much you can do with just a few lines when you use bit operators.
Also: There is a mistake in one of the photos below. Comment if you spot it!”
