Sometimes we all nee a little encouragement. Visual means seems to work great. Take a smoking habit. All you hear that smoking is harmful and expensive. But how much? This is why thoughtfix started his project called Mint-sized success meter.
The idea was to make a small device that would always remind how you haven’t been smoking and how much money you’ve saved. Device is based on Arduino Pro Mini which drives Nokia5110 LCD. Exact time is counted using Chronodot RTC. The assemble of it looks pretty straight forward – parts are mounted on small breadboard that fits inside mint-box. Adding LiPoly battery makes it neat portable reminder.
