Hello guys, i make this instructable for the people that liked the electronics and the botanic, with this you have the data about the temperatura and the humidity of your orchard and register this in a data base MySQL. For this proyect you need some knowledge of programing in PHP and MySQL, we will make […]

VO2Max is an interesting concept that proposes that there is a natural limited ability to extract Oxygen nutrient out of the air and consume it. It is like the IQ of sports activities–some algorithm that tells you how gifted you are in doing a variety of athletic contests. It was worked on at the beginning
Using a dual 7-segment display, a DS18B20 temperature sensor and a couple of shift registers I figured that I could build a digital thermometer. Step 1: Temperature Sensor The sensor I’m using is the DS18B20, it’s a 3pin sensor that just requires a single input pin from the arduino. Multiple sensors can be hooked together,
This is a chrono for measuring the speed and energy of an air rifle pellet. It’s pretty fast and could probably be used for other types of gun, (airsoft , full bore etc) but I have not tested it on them. I initially made this available as a kit of parts and info, it has
I was looking for a project that combined my three favorite things – working in my shop, building cool stuff for my bar and of course, drinking beer. After a couple of weeks in the old country drinking “the Guinness”, I decided my I’d put a keg of “Moothers’ milk” in my kegerator and prolong my vacation

The objective of this project is to measure air quality by measuring the quantity of fine particles. Thanks to its portability, it will be possible to carry out measurements at home or on the move. Air quality and fine particles: Particulate matter (PM) is generally defined as fine solid particles carried by the air (source:
Currently, we are chasing an invisible monster named Corona Virus ( COVID-19 ) and we are going through the biggest health crisis in our time due to a sharp increase in infection cases. One of the main symptoms of the COVID-19 infected person is an increase in body temperature, in addition to other symptoms such as pain
HKU Assignment Hello all!Welcome to my HKU ITTT – “If This Than That” Project. For this assignment I created a simple eye test. The Distance Measuring Eye will give you a score based on the distance away from the eye. In this Instructable I will show you my thought process and the steps I took in creating this project.
This might seem totally useless, considering how advance current technology can be and you might even be like “Tsk! a Thermometer?” But there is a lot of experiment based on temperature (water temperature, room temperature, etc) so digital thermometer becomes a key instrument for temperature measurement considering the other alternatives and cost/performance ratio. It is

A substance that is in a liquid state is constantly evaporating or passing into the gaseous state (depending on the intermolecular forces and temperature). The pressure exerted by the gaseous molecules produced in this process is known as vapor pressure. The vapor pressure depends on the temperature in such a way that at higher temperature
