A Maker by the name Vicor8o5 was frequently finding himself struggling with important decisions. Instead of toiling over making the right choice, he chose to turn to technology to help him out. He devised this clever tool to aid him in the daily decision making process.
To fix his issue, Victor8o5 set out to make the Decision Box, which makes as its name suggests, makes decisions for you by either showing a green or a red light. Outlined in a recent Instructables post, the Maker started with a small wooden cube and hollowed out a space for the technological components in the center. He wired his circuit, including a red/green light and an ATtiny85.
The code uploaded to the ATtiny85 uses a random function to produce either a red or green light. After running a test of 80 random decisions, Victor8o5 ended up with 44 reds and 36 greens. Even though that sounds like an elementary school math problem, it’s a solid distribution for this handy device!
