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 […]

What’s better in the morning than a hot cup of tea?You should keep to the brewing time so that the tea tastes the way you want it to. Unfortunately, there’s always a lot to do and the timer beeps when you’re somewhere else. So we need an automatic “tea extraction machine”….. As always, there are […]

The objectives of this project were (1) to make an object float, by means of magnetic levitation and controlled by an Arduino Nano and (2) documenting the whole process allowing other people to build one on their own. There were some requirements, too. First, I wanted an object of a certain size and weight, floating […]

At milliohm levels the fixture is part of the measurement: contact repeatability, differential ADC settings, settling and the limits of the displayed digits.

Hello all! This instructable happens to be part 3 of my ESP series where I continue to experiment and explore the various features of the ESP 8266-01 board. In the first and second part of the series I have mentioned the wonderful capability of this little board to support I2C communication and also interfaced the […]

Hello and welcome back to another Instructable. In the previous two Instructables, I have shown you how I created PCB coils in Kicad using a Python script, covered the basics of an H bridge, and showed you how I will be using them to control the segments of the 7-segment mechanical display. Make sure you […]

Now a days we are spending a lot of time at home, studying and working virtualy, so why not to make our workspace greater with a custom and smart lighting system Arduino and Ws2812b LEDs based. Here I show you how build your Smart Desk LED Light that you can control with an IR remote […]

This article describes the operation of the Schematic of Arduino Uno from the standpoint of electronic design. The majority of articles describe Arduino’s software. However, knowing hardware design enables you to move on to the next Arduino level. You can learn how to integrate an Arduino into the design of a finished product, including what […]

In this pandemic it is important to take reasonable measures to reduce spreading viruses. A paper from 2019 found that louder voices spread more viruses (https://www.nature.com/articles/s41598-019-38808-z) [Asadi et al. 2019]. This simple project aims to remind people to not shout unnecessarily. This can be used in classrooms, meeting rooms or any other setting where people […]

With 2020 being the year of COVID, having a toddler that was stuck at home (especially during the winter) presented the need for, well, stuff to do. So, my wife and I decided to turn our basement into a play place for our little girl. We started by designing and building an indoor slide with […]
