  • TiltChair is a smart office chair that will help reduce the strain of sitting all day

    The TiltChair system uses an Arduino Uno that communicates with an MPU-6050 IMU to measure the current inclination of the seat. Additionally, a BME280 pressure sensor monitors if someone is occupying the chair. To tilt the seat, the Uno employs a pair of servos that both regulate an air compressor to inflate an air bladder, thus pushing up the upper plate, or activating a vacuum pump to lower the angle. From this setup, the seat can move up to 55 degrees!

  • How to Implement a Water Tank Monitoring System Using Arduino Uno - IoT Tech Trends

    The tutorial for the project is based on wastage of water due to overflow and wastage of electricity. This happens because of the dry running of the pump in overhead water storage tanks. Hence, we would use Arduino Uno to resolve this problem by building a water tank monitoring system. Let’s understand the significance of this project before building it.

    Most of the people in residential areas face the problem of running out of water. Additionally, the overflow of water in tanks is because of an excess supply of water. It becomes difficult for users to judge the level of water in water tanks. When the pump is on, users may not realize the level of water, which may result in an overflow.

    A tank monitoring system can sort out the issues associated with a water tank. Thus, it is also possible to check the level of the water using a sensor so that whenever the water goes low, the pump turns on automatically. Also, to avoid the overflow of water, it detects when the water level goes above the set limit, which turns off the pump automatically.

  • OpenMV PureThermal STM32H7 board overlays thermal map on RGB image - CNX Software

    We’ve been writing about OpenMV open-source camera boards programmable with MicroPython at least since 2015, with the latest model OpenMV Cam H7 based on STM32H7 Cortex-M7 microcontroller introduced in 2018. But the company has now gone a step further with OpenMV PureThermal board equipped with a more powerful STM32H7 dual-core Arm Cortex-M7/M4microcontroller, and supporting FLIR Lepton 2 to 3.5 thermal imagers, allowing the system to overlay the thermal map on top of the image like an augmented reality app would do. It can do so on the integrated LCD display or on an HDMI display.

  • Locked In A Remote Control Car

    It’s rare to find modern technology that’s actually on your side. For the most part when technology advances today, new features are less for your benefit, and more to benefit the company that made them.

    Whenever I hear about a new piece of technology, at first I’m excited. Then, my next reaction is to wait for the other shoe to drop and discover the secret way it ends up exploiting me for the company’s benefit. It might lock me into a company’s other products, making me dependent upon them so I can’t move to a competitor. It might spy on me and sell my data. It might sell me disabled hardware or software at a discount, only to charge me more later to unlock features to make the tech usable.

    As cars become more like rolling computers, car manufacturers have been copying tech companies by designing features that let them lock in customers and remotely control car features, muddying the definition of car ownership along the way. Current trends in the automotive industry point to a future with you locked in a remote control car, your vendor holding the remote.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
