In the latest Explaining Computers video, Christopher Barnatt explains how to use servo motors with Raspberry Pi. Using servos is a great introduction to the digital making side of computing; servos allow you to control the movement of all manner of project components with your Raspberry Pi and a motor controller attached to its…
Andy Bradford has been wanting to upgrade their heating system for a some time – but their house is rented. Damaging the house would cause them to lose their security deposit, “so the whole system must do no damage, be made only of removable parts and be installed without modifying any of the existing…

This project goes over the process I used to create an automated cat food bowl, for my elderly diabetic cat Chaz. See, he needs to eat breakfast before he can get his insulin, but I often forget to pick up his food dish before I go to bed, which spoils his appetite and throws off…
Hello guys, In this tutorial, We’re going to show you how to make a DIY Led Cylinder at home. There are many circuits in the internet made with a led. One of them is led cube. The lots of led cubes in our research is quite high. So we wanted it to be a little…
In this article we’re going to run and benchmark Mozilla’s DeepSpeech ASR (automatic speech recognition) engine on different platforms, such as Raspberry Pi 4(1 GB), Nvidia Jetson Nano, Windows PC and Linux PC. 2019, last year, was the year when Edge AI became mainstream. Multiple companies have released boards and chips for fast inference…

I am posting this project because I would like everyone to have a simple place to come to play with one of these fantastic 16×16 RGB LED panels. I have grabbed ideas from other projects and modified them for this project. It gives you a great place to start with some fun panel projects…
First you have to decide you just want to make it work, for testing purposes, like on a breadboard, or make it as a final device. The difference is that if you want to use it on the go, I heavily suggest to include the isolated optocoupler and DC converter. If you wish to skip…
https://youtu.be/W-IVzD2Tul0 Ever since the dawn of time, people have begun to dispense time. First was the sundial, later appeared water clock after them was the hourglass. Millennia later was created the first pendulum clock and few centuries later the electronic watch. Today I’ll show you how to make Pixie, a wristwatch that combines both analog…
The robot arm uses three conventional PWM servos, and each angle is controlled by a variable resistor. The rotary potentiometer used B curve 10k ohm. Two DS3115 servo motors were used in the vertical direction, and MG995 servo motor was used in the swing direction. More info
On March 11, WHO (World Health Organization) officially declared the COVID-19 or SARS-CoV2 virus, a global pandemic. The situation is critical: more than 210,000 infected in 159 countries and nearly 10,000 deaths with very high contagion curves. The risk of contagion is very high due to the volatility of the virus and the long…
