  • Arduino Blog » Monitor your hoverboard’s power draw with this Arduino-based meter/logger

    If you look at your car’s dashboard, there’s a good chance you’ll find an efficiency rating for how you’re driving. However, what if you instead ride a hoverboard? This functionality is certainly not stock equipment, yet Niklas Roy wanted to understand the power consumption of his transporter during different riding situations. For that reason, he decided to develop a power monitor that not only graphs his stats when scooting around, but records the data for later viewing and analysis.

    Roy’s handheld device is controlled by an Arduino Nano and utilizes a Hall effect ammeter for current sensing. The measurements are shown as numbers and as oscillograms on a 1.8” TFT screen, which can also be logged to the display’s built-in SD card. An RTC module provides timestamp information for these readings, which can be produced using Processing and overlaid on video.

  • STM32U5 Cortex-M33 MCU gets more performance, 2D graphics accelerator, and advanced security

    The new family has a higher 160 MHz clock speed, up to 2048 KB flash, up to 786 KB RAM, a 2D graphics accelerator, several peripherals have been upgraded, and a new autonomous mode lets DMA and peripherals keep working while most of the device sleeps in order to save power.

    [...]

    The board also comes with 512-Mbit octal-SPI Flash memory, 64-Mbit octal-SPI PSRAM, 256-Kbit I2C EEPROM, as well as ARDUINO Uno V3, STMod+, and Pmod expansion connectors, plus an expansion connector for a camera module, and STLink-V3E embedded debugger.

  • Pi Day at the Raspberry Pi Foundation
  • Hello RISC-V! We got samples of the new ESP32-C3 module and it is only 13×17 mm

    We got some engineering samples of ESP32-C3 modules.

  • What is Raspberry Pi 4 “Model B”? [Ed: I'm still waiting for them to formally apologise for going behind customers' backs, making secret deals with Microsoft to put Microsoft malware on all those devices]

    Raspberry Pi has conquered the world of SoC (System on a Chip). It has already garnered millions of followers since its release in 2012. Not only is it inexpensive, but it’s also versatile, modular, and multi-purpose. It has become popular not only as a credit-sized computer board but also as a controller in electronic, robotics, and IoT projects. The size, features, and price drive the popularity of the Pi, especially in the DIY community. To keep up with the current technological trends, the tiny board has undergone plenty of upgrades over the years, and there have been many varieties so it can cater to the needs and demands of its users. In 2019, the Raspberry Pi Foundation released the fourth generation of the multi-purpose board, the Raspberry Pi 4 B. It is the most powerful Pi to date, sporting huge upgrades from its predecessors. The compact board is touted to deliver a PC-level performance, and it didn’t disappoint.

  • Kentaro Hayashi: Grow your ideas for Debian Project

    There may be some "If it could be ..." ideas for Debian Project. If idea is concreate and worth to make things forward, it should make a proposal for Project Funding. [...] I'm not confident whether mechanism works, but Debian needs change.

  • Sam Thursfield: Calliope, slowly building steam

    There are some interesting complexities to this, and in 12 hours of hacking I didn’t solve them all. Firstly, Bandcamp artist and album names are not normalized. Some artist names have spurious “The”, some album names have “(EP)” or “(single)” appended, so they don’t match your tags. These details are of interest only to librarians, but how can software tell the difference? The simplest approach is use Musicbrainz, specifically cpe musicbrainz resolve-ids. By comparing ids where possible we get mostly good results. There are many albums not on Musicbrainz, though, which for now turn up as false positives. Resolving Musicbrainz IDs is a tricky process, too — how do we distinguish Multi-Love (album) from Multi-Love (single) if we only have an album name? If you want to try it out, great! It’s still aimed at hackers — you’ll have to install from source with Meson and probably fix some bugs along the way. Please share the fixes!

  • Neovide Is A Graphical Neovim Client Written In Rust

    Neovide is a really cool GUI client for Neovim. Although it essentially functions like Neovim in the terminal, Neovide does add some nice graphical improvements such as cursor animations and smooth scrolling. It even has me thinking about making it my new "vim" alias.

Linux 5.11.13, 5.10.29, 5.4.111, 4.19.186, 4.14.230, 4.9.266, and 4.4.266

Get involved with Mageia, become a Packager

With Mageia 8 just released and development for Mageia 9 getting underway in Cauldron, the unstable branch of Mageia, now is a great time to get involved with packaging. We are starting to look at the features that we want to include for Mageia 9, and as it is so early in the development cycle, now is the time for major developments, or big updates to key pieces of software. This is a great time to join the project as you can propose features you would like to see, help to implement large changes or see how a distribution evolves through development, stabilisation and then is released. If there is an application that you are interested in, if you want to help maintain part of the distribution, or if you want to learn something new, there are many opportunities to do so with the packaging team.

Google does not want you to tell your players about your donation page

I recently updated Pixel Wheels banner image on Google Play. That triggered a review of the game: shortly after the update I received a message telling me Pixel Wheels was "not compliant with Google Play Policies". What nefarious activity does the game engage in? Sneak on users? Mine bitcoins? [...] Meanwhile you can still get the game from F-Droid or itch.io, since they do not have a problem with a link to a donation page. Read more
