Retro-style computer features 5-inch round display, Framework laptop motherboard

Ubuntu 22.04 retro computer round display

After completing a DIY Raspberry Pi Zero 2 W handheld PC earlier this year, Penk Chen has designed another, rather odd but cool-looking, DIY computer. The “Mainboard Terminal” is a retro-style computer with a round display powered by the mainboard found in Framework modular laptop. The computer has been tested to work with Ubuntu 22.04 out of the box with just a few configuration tweaks for the display, but other operating systems should also work considering the mainboard is based on an Intel Core i5-1135G7, i7-1165G7, or i7-1185G7 Tiger Lake processor. There are four main off-the-shelf electronics components: Framework laptop mainboard ($399 and up) OLKB Preonic Keyboard MX Kit V3 key ($140) 5-inch round LCD with 1080×1080 resolution plus its HDMI adapter board (550 RMB = about $82) So most of the work consisted in designing the enclosure, and Penk released the STL design files on Github under an MIT […]

You can now buy Khadas VIM4 SBC for $199.90

Khadas VIM4 single board computer was first unveiled last October with Amlogic A311D2 octa-core Cortex-A73/A53 processor, 8GB LPDDR4X, but it’s only been launched today, and you can now buy the Khadas VIM4 board for right under $200. It is an upgrade to Khadas VIM3 Pro launched with Amlogiv A311D hexa-core processor a few years ago, and our testing in Android 11 revealed the main benefit may be the upgrade GPU that delivered a 67% boost in 3DMark, but CPU multi-core performance and memory bandwidth will also see some benefits over Amlogic A311D, even against in overclocked systems like ODROID N2+. Here’s a reminder of Khadas VIM4 specifications: SoC – Amlogic A311D2 octa-core processor with 4x Arm Cortex-A73 cores @ up to 2.2 GHz and 4x Cortex A53 cores @ up to 2.0 GHz, Arm Mali-G52 MP(8EE) GPU, (Note: no NPU at this time) System Memory – 8GB LPDDR4X @ 2016 […]

Bee Motion ESP32-S2 PIR motion sensor offers GPIOs, over a year of battery life

Smart Bee Designs’ Bee Motion is an ESP32-S2 board with a PIR motion sensor, some GPIOs for expansion, and promising over a year of battery life under the right circumstances. If the name “Bee Motion” rings a bell, it’s because we covered the Bee Motion Mini board last month with an ESP32-C3 processor and a PIR sensor, but no USB port for programming and no expansion ability. It was just designed to be used as a battery-powered wireless PIR motion sensor. The Bee Motion expands the use cases of the solution, although it only features WiFi connectivity, and loses Bluetooth LE. Bee Motion specifications: Wireless module – Espressif ESP32-S2-MINI-1 module with Espressif ESP32-S2FH4 single-core 32-bit LX7 microcontroller @ up to 240 MHz, RISC-V ultra-low-power co-processor, 320 kB SRAM, 128kB ROM, 2.4 GHz WiFi 4 connectivity, 4MB flash, PCB antenna PIR sensor – Passive infrared motion sensor with dome lens, 5-meter […]

Android 13 Beta for TV available for Google ADT-3 devkit

Google released the first Android 13 Developer preview in February, and we know quite a lot about Android 13 including virtualization support, as well as security and privacy updates. But the company has now released Android 13 Beta for TV (aka Android 13 for Android TV) for Google ADT-3 developer kit and the Android Emulator for TV in Android Studio. The beta release allows app developers to test their apps and provide feedback on the latest release before it is released to customer devices. Google does not provide any changelog specific to Android 13 for Android TV, but you’ll find the OS image for ADT-3 and installation instructions on the release page. Mishaal Rahman tried it on his ADT-3 box expecting some new features, but he noted that expanded PiP support, low power standby ( which could disable wakelocks and cut off network access to apps in order to preserve […]
