  • PIR Motion Sensor with Arduino Uno: hc-sr501 Wiring, Setup, and Coding - peppe8o

    Detecting motion inside a monitoring area, such as security area or home restricted place, requires monitoring all the object moves within thas perimeter. The PIR sensor (HC-SR501) with Arduino is a good and cheap option, as it has ability to measure up to 7 meters

  • This dad converted a Power Wheels into a DIY fire truck toy, complete with a siren and lights | Arduino Blog

    After searching everywhere for an affordable ride-on fire truck toy for his daughter this past Christmas season YouTuber Jason Altice (AKA CodeMakesItGo) had nearly given up, but luckily enough was able to locate a free Grave Digger Power Wheels that he could modify into one. In its current condition, the vehicle was in bad shape so it had to first be almost completely disassembled, which led to the discovery of a bad switch that was causing the troubles.

    Upon removing each panel and meticulously painting it with coats of primer and bright red paint, Altice moved onto the next step of including a loud siren and some lights for additional realism. He took an Arduino Nano, loaded some sounds in the form of tone melodies, and then ran the outputted signal from the digital pin to an amplifier and onwards to the horn.

  • This Arduino monitor helps prevent bedridden patients from getting pressure sores and more | Arduino Blog

    For people who are recovering from a major surgery or those who have a disability, ensuring proper posture while lying down for extended periods of time is vital for reducing joint pain and other ailments that come about from a lack of movement, including pressure sores. Rodrigo Mejiasz’s project aims to solve the issue by using a small device that monitors how long a patient has been lying down in one position and alerts a caregiver when it’s time to adjust them.

  • Monitor For Bedridden Patients Aims To Improve Care | Hackaday

    One of the joys of being a Maker and Hacker is solving problems and filling needs. When you can do both, well, that’s something special. [rodrigo.mejiasz]’s project surely fits into that special category of solving a problem and filling a dire need with his Bedridden Patient Monitor.

    While [Rodrigo]’s project page does not specify his motivation for creating this project, one only needs to look as far as their local hospital ward or senior care facility to understand why this device is so wonderful. Healthcare workers and caregivers are stretched paper thin, and their attention is being constantly interrupted.

Hackers getting married

We had several of our old-time friends from the GNU Project, and some guests with young children still unused to such an international context who soon enough learned to enjoy the sound of different languages and the happy chaos of people meeting for the first time, some more traditional if not formal, others fun and weird.

  • Red Hat Enterprise Linux 8.6: Better security, more options

    Do you want a solid Linux distribution that also delivers the latest languages and solid security? Yes? Then consider getting Red Hat Enterprise Linux 8.6. Red Hat announced this new release at the Red Hat Summit. It has numerous new features, but the ones that caught my eye were the security improvements.

  • OS consistency solves Linux talent issues, says RHEL executive

    The new Red Hat Enterprise Linux, released during the recent Red Hat Summit, caters to rapidly escalating hardware development occurring throughout tech, along with a growing Linux admin skills shortage. RHEL 9 performs the combo double act, in part, by more efficiently optimizing the operating system, according to Gunnar Hellekson (pictured), general manager of the Enterprise Linux Business Unit at Red Hat Inc. Upgrading to the new OS means enterprises can get by with fewer admins. A skills shortage is caused, in part, by a lack of U.S. visas.

These two Linux desktops are the simplest picks for new users

Let's face it, any time you come across articles that offer advice on choosing the right Linux distribution, they tend to get bogged down in a lot of technical advice that rarely (if ever) applies to those who've never experienced Linux. They'll speak of things like rolling releases, package managers, kernels, open-source licensing, and other features and ideologies that not only have little bearing on those new to Linux and open-source technology but mire the decision in unnecessary complications. I want to take a very different approach, one that should make the process quite simple for anyone looking to dive into the world of desktop Linux for the first time. I'm going to shrug off the usual advice and aim straight for the heart of the matter. What exactly is that matter? Read more
