Many plants are notorious for how picky they are about their environmental conditions. Having the wrong temperature, humidity, soil type, and even elevation can produce devastating effects. But none are perhaps as important and overlooked as water/soil pH, which is a measure of how acidic and/or alkaline the growing medium is. In hydroponics, maintaining optimal […]
Nothing is perhaps more frustrating than suddenly discovering your favorite battery-powered device has shut down due to a lack of charge, and because almost no one finds joy in calculating how long it will live based on current consumption levels/time used, there must be a better way. This problem is what inspired Manivannan S. to […]
Within an industrial setting, being able to determine if and/or when a machine malfunctions is vital to maintaining safety and uptime. This challenge is what prompted a maker who goes by javagoza on element14 to enter into their Design for a Cause 2021 contest with his device, which he calls the VenTTracker. At its heart, the VenTTracker uses an Arduino […]
Shortly after the COVID-19 pandemic began, Samuel Alexander and his housemates purchased a ping pong set and began to play — a lot. Becoming quite good at the game, Alexander realized that his style was not consistent with how more professional table tennis players hit the ball, as he simply taught himself without a coach. Because of […]
Whether commuting to work or simply having fun around town, riding a bike can be a great way to get exercise while also enjoying the scenery. However, riding around on the road presents a danger as cars or other cyclists / pedestrians might not be paying attention while you try to turn. That is why Alvaro […]
Throughout the day as the sun evaporates the water from a plant’s leaves via a process called transpiration, observers will notice that they tend to get a little bit droopy. Also known as drought stress, this response to a loss of water results in low turgidity (internal water pressure) and can impact the ability of the […]
AIfES is a standalone AI framework completely written in C. It allows on-device training without a PC and can be used on almost any hardware; even the 8-bit controller of the Arduino Uno.
A dangerous fall can happen to anyone, but they are particularly dangerous among the elderly as that demographic might not have effective ways to get help when needed. Rather than having to purchase an expensive device that costs up to $100 per month to use, Nathaniel F. on Hackster wanted to build a project that harnessed the power of […]
One major drawback to the largescale farming of animals for meat consumption is the tendency for diseases to spread rapidly and decimate the population. This widespread issue is what drove Clinton Oduor to build a tinyML-powered device that can perform precision livestock farming tasks intelligently. His project works by continuously monitoring the noise coming from pigs and makes a […]
There are thousands of bird species in the world, with numerous different and unique ones living in various areas. Developers Errol Joshua, Mahesh Nayak, Ajith K J, and Supriya Nickam wanted to build a simple device that would allow them to automatically recognize the feathered friends near them and do some simple tracking, such as […]
