You’ve heard it 1,000,000 instances: it is very important keep hydrated. So, just like the dutiful caretaker of your individual physique that you’re, you go replenish a glass of water and take it again to your desk. Then 4 hours move and also you look down to comprehend you haven’t taken a single sip. Dehydration lurks simply across the nook, you idiot! This Annoying Coaster prevents such hazard by refusing to allow you to ignore your water.
This “coaster” is basically only a dressed-up digital scale. Besides it’s dressed up as a really obnoxious baby that received’t cease poking at you. Place your glass on the coaster and it’ll measure the load. Every time you decide up the glass to take a drink after which set the glass again down, the coaster measures the load once more. If an excessive amount of time passes between drinks or the load is dropping quick sufficient, the coaster will begin attempting to get you to hydrate.
It does that primarily by way of flashing RGB LED lights. These ought to be sufficient to behave as a pleasant reminder. However in the event you ignore them and proceed strolling down that harmful and, frankly, immoral path in the direction of dehydration, it’ll blare an alarm at you.
That will probably be too irritating to disregard, so that you’ll both drink some water or throw the coaster in a trash can.
The {hardware} is easy: simply an ESP32 dev board measuring weight by way of amplified load cells. A small OLED display reveals the standing and weight measurements. The indicator lights are on a KY-009 RGB LED module and the alarm buzzer is a buzzer. These parts go in a slim 3D-printed enclosure.
I personally consider that individuals make too large of a deal about hydration and that your physique will let you know if you want water. However in the event you don’t share my opinion and in addition like habit-building by way of abusive motivation, that is the coaster for you.
