Light sensors add “lift and learn” feature to digital signage player

Light sensors with digital signage lift and learn

Light sensors are used to turn on/off lights, adjust the brightness of displays, and more. But I’ve come across a use case I never thought of: object presence detection. In the digital signage work, such features if called “lift and learn”, and light sensors are used to detect when an object is present and play a video or display information about the product. That concept came to my attention when I saw a photo of Mekotronics R29 digital signage player with several cables coming out of the device and attached to what looked like white hockey pucks and turned out to be light sensors. Apart from the light sensors, Mekotronics R29 specifications are pretty standard: SoC – Rockchip RK3399 hexa-core processor with 2x Cortex-A72 cores, 4x Cortex-A53 cores, Arm Mali-T860MP4 GPU, 4K VP9, H.264, H.265, and 1080p60 VC-1, MPEG-1/2/4, VP6/8 video decoder System Memory – 4GB DDR Storage – 64GB […]

Armbian 22.05 release adds support for Orange Pi R1 Plus LTS, Radxa Zero & Rock 3A, DevTerm A06

The latest release of Armbian, version 22.05, is now out with hundreds of Linux kernel and user space-related bug fixes, a focus on stabilizing existing platforms, while still adding four new boards with Orange Pi R1 Plus LTS (RK3328), Radxa Zero (Amlogic S905Y2), Radxa Rock 3A (RK3568), and DevTerm A06 (RK3399). The community also added two new maintainers for ESPRESSObin and Radxa Rock Pi 4 (Model A) SBCs which should mean the images for those boards will be tested more regularly and potential issues fixed more quickly. You may want to read the more detailed changelog to see if any changes may impact the board(s) you are using. The new Armbian 22.05 release succeeds Armbian 22.02 outed on February 28, 2022. If you’d like to upgrade simply run those two commands on your existing installation:

sudo apt update
sudo apt upgrade

1 2	sudo apt update sudo apt upgrade

For new installation, browse the list of supported boards, select the Debian/Ubuntu image you’d […]

ROCK Pi 4 Model C+ SBC features 1.5 GHz Rockchip RK3399-T CPU, dual HDMI output

ROCK Pi 4 Model C+ is a single board computer (SBC) by a Rockchip RK3399-T hexa-core processor @ 1.5 GHz, equipped with 4GB RAM, and two micro HDMI ports to drive up to one 4K display, and one 2K display. It is yet another ROCK Pi 4 SBC from Radxa, and the first to use the down-clocked RK3399-T processor with other models based on Rockchip OP1 processor clocked at 2.0GHz (overclockable to 2.2/2.4GHz) or the traditional Rockchip RK3399 @ 1.8 GHz (overclockable to 2.0 GHz), and also the first of the family to offer dual HDMI output. ROCK Pi 4 Model C+ specifications: SoC – Rockchip RK3399-T big.LITTLE hexa-core processor with 2x Arm Cortex-A72 @ up to 1.5 GHz (up to 2.0 GHz overclock) 4x Cortex-A53 @ up to 1.4 GHz (up to 1.6 GHz overclock). Note the processor datasheet says the Cortex-A53 cores are limited to 1.0 GHz, but […]

ASUS Tinker Edge R SBC with 3GB RAM, Rockchip RK3399Pro sells for $179

ASUS Tinker Edge R Pico-ITX single board computer with Rockchip RK3399Pro AI processor was first unveiled in 2019 with 6GB RAM, but a cheaper 3GB RAM version with 2GB RAM for the CPU, and 1GB RAM with the integrated NPU just showed up in my news feeds. Whether it comes with 3GB or 6GB RAM, the Tinker Edge R board should mostly be interesting for AI accelerated workload thanks to the 3 TOPS built-in NPU, as well as the two MIPI CSI camera interfaces. ASUS Tinker Edge R (3GB) SBC specifications: SoC – Rochchip RK3399Pro hexa-core big.LITTLE processor with 2x Cortex A72 cores up to 1.8 GHz, 4x Cortex A53 cores @ 1.4 GHz, an Arm Mali-T860 MP4 GPU up to 800 MHz with OpenGL ES 1.1 to 3.2, OpenVG1.1, OpenCL 1.2 and DX 11 support, and NPU delivering up to 3.0 TOPS System Memory – 2 GB dual-channel LPDDR4 […]

Capyloon mobile Web-based OS works on Pinephone Pro, Librem 5, Pixel 3a

Capyloon is an experimental Web-based OS leveraging b2gOS that served as the base for the now-defunct Firefox OS. The developers’ goal is to provide an open-source OS improving privacy and user control through web technologies. It’s still early stage, and some of the technologies used include the IPFS protocol, WebAssembly plugins, and the Tor network. Capyloon is more like a new phone shell as it replaces Phosh when installing it in a Linux smartphone. The first version of Capyloon released last month worked on Pixel 3a, other Android phones through a generic system image, and 64-bit x86 Debian machines. But since then, the developers added support for Apple M1, and yesterday they released Debian packages for PinePhone Pro and Librem 5 Linux smartphones to run Capyloon on top of a Mobian image. Instructions are as follows: Download the Debian package for PinePhone Pro or Librem 5 Install the package withsudo […]

Linux 5.17 release – Main changes, Arm, RISC-V, and MIPS architectures

Linus Torvalds has just released Linux 5.17: So we had an extra week of at the end of this release cycle, and I’m happy to report that it was very calm indeed. We could probably have skipped it with not a lot of downside, but we did get a few last-minute reverts and fixes in and avoid some brown-paper bugs that would otherwise have been stable fodder, so it’s all good. And that calm last week can very much be seen from the appended shortlog – there really aren’t a lot of commits in here, and it’s all pretty small. Most of it is in drivers (net, usb, drm), with some core networking, and some tooling updates too. It really is small enough that you can just scroll through the details below, and the one-liner summaries will give a good flavor of what happened last week. Of course, this means […]
