ZX Spectrum Next Retro Keyboard PC Relies on Xilinx FPGA, Raspberry Pi Zero “Accelerator” Board (Crowdfunding)

ZX Spectrum keyboard computer was launched in April 1982 in the United Kingdom, and 35 years later, a team of developers has now been working on ZX Spectrum Next somewhat resuscitating ZX Spectrum by emulating Z80 processor in a Xilinx FPGA, using an optional Raspberry Pi Zero board as an accelerator, and adding some modern features like HDMI output and WiFi. While the case is only a 3D rendering for now, they have a working board prototype with the following specifications: FPGA – Xilinx Spartan-6 FGPA emulating Z80 processor in 3.5Mhz and 7Mhz modes System Memory – 512KB RAM (expandable to 1.5MB internally and 2.5MB externally) Storage – SD Card slot, with DivMMC compatible protocol used in the original ZX Spectrum Video Hardware sprites, 256 colours mode, Timex 8×1 mode etc. Output: RGB, VGA, HDMI Audio – 3x AY-3-8912 audio chips with stereo output + FM sound Networking – Optional […]

GPU Accelerated Object Recognition on Raspberry Pi 3 & Raspberry Pi Zero

You’ve probably already seen one or more object recognition demos, where a system equipped with a camera detects the type of object using deep learning algorithms either locally or in the cloud. It’s for example used in autonomous cars to detect pedestrian, pets, other cars and so on. Kochi Nakamura and his team have developed software based on GoogleNet deep neural network with a a 1000-class image classification model running on Raspberry Pi Zero and Raspberry Pi 3 and leveraging the VideoCore IV GPU found in Broadcom BCM283x processor in order to detect objects faster than with the CPU, more exactly about 3 times faster than using the four Cortex A53 cores in RPi 3. They just connected a battery, a display, and the official Raspberry Pi camera to the Raspberry Pi boards to be able to recognize various objects and animals. The first demo is with Raspberry Pi Zero. […]

Flint OS is a Chromium OS Build for Raspberry Pi & Firefly-RK3288 Boards

Chromium OS for SBC aimed to bring Chromium operating systems to low cost development boards such as the Raspberry Pi 3 board, but the website is now down, and the developer announced he had stopped working on it several months ago due the hardware limitations of the Raspberry Pi 3 board. But others decided it was still worth the effort, and created Flint Innovation company (based in UK/China) to develop Flint OS, a build of Chromium OS with optimizations for Raspberry Pi 3 and Firefly-RK3288 boards with more boards likely coming soon. The developers also provide an x86 image, but after asking more details, it turns out they only changed the boot splash screen for now on the x86 image, with most of the early work done on Raspberry Pi board: At this moment our public Flint OS releases are still pretty much vanilla Chromium OS (we changed the boot […]

$40 NanoPi K2 Board Powered by Amlogic S905 Processor Competes with ODROID-C2, Raspberry Pi 3

Hardkernel ODROID-C2 board is getting some direct competition with FriendlyELEC’s NanoPi K2 development board powered with Amlogic S905 processor with 2GB RAM, a very similar form factor, and many of the same features, which together with Khadas Vim (Pro) brings the number of low cost Amlogic based development boards to three. NanoPi K2 board specifications with differences compared to ODROID-C2 highlighted in bold or stricken-through: SoC – Amlogic S905 quad core cortex-A53 processor @ 1.5 GHz with penta core Mali-450MP GPU System Memory – 2GB DDR3 Storage – eMMC module socket, micro SD slot Video Output – HDMI 2.0 up to 4K @ 60 Hz Connectivity – Gigabit Ethernet (Realtek RTL8211F), 802.11 b/g/n WiFi + Bluetooth 4.0 (AP6212 module) with chip antenna + IPX connector USB – 4x USB 2.0 host ports (GL825G USB hub) + micro USB OTG port for power and adata Expansion Header 40-pin header with GPIO, […]

OpenELEC 8.0 Released with WeTek Play 2 & Hub, and Raspberry Pi Zero W Support

In recent months, I’ve written more about LibreELEC, a fork of OpenELEC, but the latter project is still being worked on, and OpenELEC 8.0 has been released adding builds for WeTek Play 2 & WeTek Hub TV boxes, as well as Raspberry Pi Zero W board, and upgrading to Kodi 17.1. and newer packages such as Linux 4.9 and ffmpeg 3.2. The developers also removed some unused or dropped features such as HFS and HFS+ filesystem, iSCSI, NFS/NBD/iSCSI network boot, and LIRC. X11 AMDGPU, ATI (Radeon) and Intel GPU driver driver has been replaced by X11 Modesettings GPU driver. They also updated some drivers & firmware files for WLAN and DVB, as well as update Nvidia Legacy driver to xf86-video-nvidia-340 (VDPAU only supported now). You can download or update OpenELEC 8.0, not only for the new WeTek and Raspberry Pi platforms, but for also x86 64-bit images for Intel & […]

FalconGate Open Source Anti-Hackers Smart Gateway Runs on Raspberry Pi, Banana Pi, and other ARM Debian Boards

Everyday we can read stories about password database hacking, malware, ransomware, and so on, and companies can try to protect themselves by paying professionals that do a more or less good jobs, but individuals can’t afford professional service, so it is harder to protect oneself. One solution is to educate yourself as much as possible, but everybody has the time and/or skills to do it, so developers have worked on  FalconGate open source smart gateway that’s supposed to protect home devices against hackers, and alerts the user in case of intrusions on your home network, or devices misbehaving. FalconGate is said to be able to: Block several types of Malware based on open source blacklists Block Malware using the Tor network Detect and report potential Malware DNS requests based on VirusTotal reports Detect and report the presence of Malware executables and other components based on VirusTotal reports Detect and report […]
