  • ANAVI Gardening uHAT adds soil and other sensors to Raspberry Pi (Crowdfunding) - CNX Software

    We’ve been covering and reviewing ANAVI open-source hardware boards for several years now, either standalone boards based on ESP8266, or add-on boards for Raspberry Pi.

    The ANAVI Gardening uHAT is the latest board from Leon Anavi. It is a micro HAT designed for Raspberry Pi Zero to Raspberry Pi 4 SBCs that offers interfaces for soil sensors and other environmental sensors allowing measurements of soil moisture, atmospheric pressure and humidity, temperature with a waterproof sensor, and light intensity for gardening applications.

  • ZB-GW03 ESP32-based Ethernet Zigbee gateway works with Tasmota firmware - CNX Software

    ZB-GW03 is an Ethernet Zigbee Gateway compatible with eWelink mobile app and with a design similar to SONOFF ZBBridge gateway but replacing ESP8266 SoC by ESP32 SoC, and adding an Ethernet port.

    The ZB-GW03 gateway is apparently based on the same Silicon Labs EFR32MG21 Zigbee Arm Cortex-M33 chip and has been hacked to run Tasmota open-source software for people preferring more flexibility and/or integration with OpenHAB or Home Assistant open-source home automation frameworks via Zigbee2MQTT.

  • Arduino Orchestra Plays The Planets Suite | Hackaday

    We’ve seen a great many Arduino synthesizer projects over the years. We love to see a single Arduino bleeping out some monophonic notes. From there, many hackers catch the bug and the sky is truly the limit. [Kevin] is one such hacker who now has an Arduino orchestra capable of playing all seven movements of Gustav Holst’s Planets Suite.

    The performers are not human beings with expensive instruments, but simple microcontrollers running code hewn by [Kevin’s] own fingertips. The full orchestra consists of 11 Arduino Nanos, 6 Arduino Unos, 1 Arduino Pro Mini, 1 Adafruit Feather 32u4, and finally, a Raspberry Pi.

  • 3D Printed Research Robotics Platform Runs Remotely | Hackaday

    By patching Ubuntu Linux, and enabling preemptive multitasking for real-time scheduling, as well as carefully selecting Wi-Fi drivers, it was possible to get raw packets out to robot in about 1 ms, enabling control loop bandwidths of around 1 Khz. And, that, was fast enough to run at least sixteen motors in parallel.

  • Automated Window Blinds Using MQTT And Home Assistant | Hackaday

    Finnish software engineer [Toni] is on a quest to modernize his 1991 house, and his latest project was to automate the window blinds and control them using Home Assistant. Unless your blinds have built-in motors, most of the effort of such a project centers around how to integrate and attach the motor — and as [Toni] points out, there are tons of different blinds with all kinds of operating mechanisms. But once you solve that issue, half the battle is over.

    These particular blinds require less than one turn of the control rod to go from fully open to fully closed, and [Toni] selects a 270-degree range-of-motion, 20 kg*cm torque servo motor to drive them. He really wanted to install the motor inside the window, but it just wouldn’t fit. Instead, each servo motor is mounted in a custom 3D-printed case installed on the window frame just below the operating rod. An ESP8266-based controller box is installed above the window, hidden behind curtains, and operates all three servos.

  • Another Step in Automating the Pageload Recordings

    In a previous article, Kimberly Sereduck told us about Updates to Warm Page Load Tests and how we are continuously working to make our tests more representative of real user behavior. Besides that, we are working on automating the process of recording the website’s page load.

  • Practicing lean data is a journey that can start anywhere - Open Policy & Advocacy

    “It’s not about the destination, but about the journey.” I’m sure data and privacy are the furthest from your mind when you hear this popular saying. However, after a year of virtually sharing Mozilla’s Lean Data Practices (LDP), I’ve realized this quote perfectly describes privacy, LDP, and the process that stakeholders work through as they apply the principles to their projects, products, and policies. [...] There is an appetite to understand how we as consumers can hold companies accountable. One of the biggest surprises for me came when I would field questions at the end of a presentation, and people would ask about their rights as consumers and how they can hold companies accountable. For example, people wanted to understand their rights and recourse options if companies contacted them without permission, didn’t honor their unsubscribe requests, or did something else frustrating. I teach LDP for individuals to apply it in a business context, but we are all also consumers and customers. LDP can help us better understand how our own data should be handled and improve our understanding of what organizations are doing. We can then remember how we feel about certain situations and then ensure we are doing things in a more consumer-friendly way within our organizations. Lean Data Practices is a journey. For many there won’t be an ultimate destination because it is an iterative process. If you try to apply all the principles across your entire organization at once, you will find yourself overwhelmed and likely unsuccessful. To maximize your chance of success, my advice — which is the same advice we give when we present — is to just start somewhere. Choose one aspect of your business and focus on that, one pillar at a time. Once you’ve successfully applied the principles, go to a different business unit and do the same. Remember to review and adapt as products and business needs (or data!) change as well. You may likely never reach your destination, but you will see your company improve in its practices along the way.

  • Tor vs. VPN: Is One Better than the Other?

    Tor and VPN have unique ways to ensure user privacy on the Internet. They’re fundamentally very different yet have many similar aims. Due to the overlap in features, you may be weighing the pros and cons of using one over the other. Or maybe they can be treated equally but with separate purposes. This guide digs into everything you need to know about which software should be used for more Internet anonymity.

  • New Alpha Release: Tor Browser 11.5a2 (Windows, macOS, Linux)

    Tor Browser 11.5a2 is now available from the Tor Browser download page and also from our distribution directory.

    This version includes important security updates to Firefox.

Intel Core i9 12900K P-State Governor Performance On Linux Review

Since Intel's Alder Lake launch one of the test requests to come in a few times has been about the Intel P-State CPU frequency scaling driver and how its performance differs with the various governor choices available for altering the CPU frequency scaling behavior. Now that Linux 5.16 stable is out and running in good shape on Alder Lake, here are some Core i9 12900K benchmarks looking at various CPU frequency scaling choices and their impact on raw performance as well as CPU thermals and power consumption. With Alder Lake having seen fixes in Linux 5.16 as well as ADL-S graphics being enabled by default on this new kernel, it's a good target for carrying out the P-State testing. The main reader inquiry has obviously been about how how well these new Intel hybrid processors perform if moving from P-State "powersave" as is often the default governor on most distributions to instead using the "performance" governor that tends to keep the CPU in its higher performance states more aggressively than powersave.
