  • World’s first fingerprint sensor HAT uses capacitive scanning

    SB Components has won Kickstarter funding for a $60 “PiFinger” HAT for the Raspberry Pi featuring a 2D capacitive fingerprint sensor with 176 x 176 resolution that can detect, compare and register up to 24 fingerprints.

    UK-based SB Components, which has delivered ambitious, Raspberry Pi based products such as its PiTalk phone, LapPi laptop, and PiArm robotic arm, has weighed in with what it calls the world’s first fingerprint sensor HAT. The open source, $60 PiFinger has won Kickstarter funding and will ship in February.

  • Compact Jetson Xavier NX/ Nano open hardware baseboard supports Android

    When it comes to NVIDIA Jetson family of modules, we should understand that NVIDIA Jetson Nano is for makers and STEM education, while Xavier NX is more geared towards professional and commercial use. The compute module Xavier NX was announced before the development kit, which includes the module and reference carrier board and otherwise for NVIDIA Jetson Nano. There are some third-party carrier boards & edge computers available for Jetson Xavier NX and Jetson Nano, including DesignCore Carrier Board and Diamond FLOYD Carrier Board. Antmicro, a custom hardware, software, and AI engineering company, came up with a compact open hardware device: Jetson Nano/ Xavier NX baseboard. It supports both NVIDIA Jetson Nano SoM as well as the Xavier NX SoM.

  • ST adds FreeRTOS thread-aware debug for microcontrollers

    STMicroelectronics has added support for FreeRTOS thread-aware debug to its STM32CubeIDE development environment, completing its acquisition of the Atollic tools.
    ST has completed transferring major advanced features of Atollic TrueStudio for STM32 into STM32CubeIDE after acquiring Atollic in 2017. STM32CubeIDE with support for thread-aware debug of the open source FreeRTOS real time operating system further extends the tool’s features. FreeRTOS is now supported by Amazon as AmazonFreeRTOS for the AWS cloud service.

    The direct access to STM32CubeMX configuration functions simplifies project setup, selecting a target microcontroller from the complete STM32 portfolio, configuring GPIOs, clock tree, peripherals, and pin assignments. The tool allows developers to quickly analyse power consumption depending on the applications usage, as well as select middleware stacks and generate initialization code for the desired configuration.

  • PiFinger is a Fingerprint HAT for Raspberry Pi (Crowdfunding)

    “There’s a HAT for that” they say, or something close to it… We’ve covered many HAT expansion for Raspberry Pi boards over the years, but so far, I don’t think we’ve seen any HAT with a fingerprint sensor, probable because tiny USB fingerprint readers are a thing. But if you’d like a HAT with a built-in fingerprint sensor, the guys at SB Components have you covered with PiFinger HAT equipped with a 2D capacitive fingerprint sensor and a small display.

Movim: An Open-Source Decentralized Social Platform Based on XMPP Network

Just like some other XMPP desktop clients, Movim is a web-based XMPP front-end to let you utilize it as a federated social media. Since it relies on XMPP network, you can interact with other users utilizing XMPP clients such as Conversations (for Android) and Dino (for Desktop). In case you didn’t know, XMPP is an open-standard for messaging. So, Movim can act as your decentralized messaging app or a full-fledged social media platform giving you an all-in-one experience without relying on a centralized network. It offers many features that can appeal to a wide variety of users. Let me briefly highlight most of the important ones. Read more

Revive Classic Nintendo DS Games on Linux With Emulation

Want to play Nintendo DS games on your Linux system but can't figure out how? Back in the day, Nintendo DS was a very popular handheld console with a huge collection of games. But over time, advanced consoles were launched in the market that rendered DS obsolete. Luckily, several emulators are available that allow you to play classic Nintendo DS games on your system. DeSmuMe is a great example of a stable Nintendo DS emulator for a Linux machine. Read more

Patched Linux 5.11 Continues Looking Great For AMD Ryzen/EPYC Performance

While the initial AMD Linux 5.11 performance regression written about at the end of last year was of much concern given the performance hits to AMD Zen 2 / Zen 3 processors with the out-of-the-box "Schedutil" governor, with a pending patch the regression is not only addressed but in various workloads we continue seeing better performance than even compared to Linux 5.10. Here is the latest from several more days of extensive performance testing. Read more

DIN-rail gateway offers dual LAN and dual RS485

The Unipi Gate G110 and G100 are PLC-ready DIN-rail gateways that run Linux on a quad -A53 SoC with 16GB eMMC, GbE and 10/100 LAN ports, and up to 2x RS485 ports with modular extensions. Czech based Unipi, which started out in 2014 with a Raspberry Pi based UniPi automation controller board and followed up with products including an Allwinner H5-based Axon automation controller, has now launched the $243 Unipi Gate G100 and $272 Unipi Gate G110 DIN-rail gateways.
