The purpose of this Instructable is to build a portable device that can measure the speed of sound in refrigerant gases and use this data to identify them. The speed of sound in an ideal gas is related to two characteristics of the gaseous substance, its molecular mass (kg/mol) and its adiabatic constant (heat capacity ratio), or …

Once I failed to control the drone because of the wind so I want to measure the wind speed to know whether it is suitable for the drone flight in the wild. So I am thinking of how to measure the wind speed in the field I can check it anywhere remotely. Thanks to Arduino …
This tutorial shows how to move two stepper motors so they will synchronously arrive at defined destination point. There are many sophisticated solutions for doing this such as GRBL or Marlin. Using an Arduino, there are also dedicated “Multi Stepper” libraries that can support you. However, we will use a more basic approach here making it as easy as possible …

Overview This “Internet Speed Gauge” will give you near real time oversight of your network usage. This information is available on the web interface of most home routers. However, accessing it requires you to stop your current task to go look it up. I wanted to view this information without having to interrupt my current …
As most electronic engineers and hobbyists do, I have a great respect for the earlier ways of controlling electrons, before it was found out that silicon could be used to miniaturize everything a thousandfold. It is amazing that things like a vacuum, a glow wire and a bunch of strange-looking metal bits can actually do …
