NODE Mini Server V2 is a Raspberry Pi Based Storage Server for the Decentralized Web

We’ve previously covered networked hard drive enclosures with Ethernet and/or WiFi running OpenWrt or Ubuntu that allows you to easily and fairly cheaply connect SATA drives to your local network with models such as Blueendless X3. NODE has done something similar with a DIY project featuring a Raspberry Pi 3 Model B+. NODE Mini Server V2 connects the popular SBC to a 2.5″ SATA hard drive over USB and is designed to build out the physical infrastructure for the decentralized web (e.g. IPFS) that would allow users to replace remote servers with nodes that they themselves own and operate. Having said that nothing would prevent you from using this as a simple NAS although performance will not be as optimal as the aforementioned products due to the lack of SATA or USB 3.0 interface, as well as having “Gigabit” Ethernet limited to 300 Mbps. Having said that the design could […]

Google Glass Enterprise Edition v2 Features Snapdragon XR1 Processor

To be honest, I was pretty happy when it was clear that smart glasses for the consumer market would not take off, and I would be living in a better, smart glasses-free, world. But I also reckoned that those could have use in professional settings, and Google Glass Enterprise edition was first spotted in 2015 with an Atom processor. The company has now launched an upgraded model with Google Glass Enterprise Edition v2 powered by Qualcomm Snapdragon XR1 eXtended reality (XR) platform. Google Glass Enterprise Edition v2 specifications: SoC – Qualcomm Snapdragon XR1 quad-core Kryo processor @ 1.7GHz with Adreno GPU, Qualcomm AI Engine for on-device processing; 10nm manufacturing process System Memory – 3GB LPDDR4 Storage – 32GB eMMC flash storage Display – 640×360 Optical Display Module Audio out – Mono Speaker, USB audio, BT audio Microphones – 3 beam-forming microphones Camera – 8MP, 80 DFOV Connectivity – Wi-Fi 5 […]

MBCFET Process Technology to Enable 3nm Chips in 2021

We often read new processor are manufactured with a FinFET process. The new process was created due to short channel effects in traditional planar transistors, and FinFET (Fin Field-effect transistor) was introduced to enable further voltage scaling but with the process node becoming smaller and smaller, electrostatics effects started to cause problem. A solution was to use GAA (Gate All Around) nanowires to limit those effects, but those are apparently really hard to integrate into silicon, so Samsung ended up using thin layers (nanosheets) instead of nanowires enabling greater current per track in their GAA implementation called MBCFET (Multi-Bridge Channel Field-Effect Transistor). While FinFET starts to encounter limitations under 4-5nm, MBCFET will enable manufacturing of chips using a 3nm process. Silicon designers can get started straight away as Samsung Foundry has recently announced the release of their 3GAE PDK (Process Design) version 0.1. Compared to 7nm FinFET technology, Samsung’s 3GAE […]

Programmable-Air is an Arduino Nano Powered Pneumatics Kit (Crowdfunding)

Programmable-Air Arduino Nano Pneumatics Kit

Programmable-Air is a hardware toolkit that allows you to inflate and deflate objects. Powered by an Arduino Nano board, the kit comes with high pressure and vacuum pumps, valves, and a pressure sensor that enables users to experiement and learn about pneumatics and inflatables. Some of the potential applications include vacuum pick and place machines, soft robots able to walk, soft robotics hands, using a syringe as a linear actuator, inflatable bras, arts projects and more. Programmable-Air specifications: MCU Board – Arduino Nano board based on Microchip ATMega328P microcontroller Pneumatics – Full channel control, i.e. high pressure through atmospheric pressure to vacuum output in the same tube.

Raspberry Pi based Hyper Keyboard Pi & hgTerm Handheld PCs, and RasPi Arcade Stick

hgterm DIY Raspberry Pi Handheld Computer

There are so many products and projects based on Raspberry Pi that it’s difficult to keep track, and many are often not that interesting, not because they are not useful, but instead because it just feels we’ve seen those before. But this week I’ve come accross three projects that looks to be newsworthy including two handheld computers with a 4″ display, and one retro-gaming console with standard arcade buttons and controls similar to what is found in Pandora’s Box/Key 5S. hgTerm DIY Raspberry Pi Handheld Computer hgterm is a portable computer based on a stripped down Raspberry Pi 3 where the Ethernet port, HDMI port, and most of the USB ports have been removed. It features a 4″ touchscreen display, a Bluetooth keyboard all housed in a 3D printed case. It’s not actually a product that you can buy (yet), but a project made by Igor Brkić which you can […]

Blueendless X3 Networked “HDD NAS Case” Runs Ubuntu on Marvell ARMADA 3720 SoC

We’ve previously covered inexpensive Kimax’ Ethernet & WiFi HDD enclosures for 2.5″ SATA drives, powered by MediaTek processor and running OpenWrt. If you need something more powerful and versatile yet still affordable, the easiest way is now likely to go with SBC based solutions such as ODROID-HC1/HC2 or dual SATA NAS enclosure for RockPro64. There may be another interesting option, as I’ve just been informed about another model of those networked HDD enclosure called Blueendless X3 “HDD NAS case” with Ethernet only (no WiFi), and that is equipped with the same Marvel ARMADA 3720 dual core Cortex-A53 processor as found in Marvell ESPRESSOBin board. Blueendless X3 specifications: SoC – Marvell ARMADA 3720 (88F3720) dual core Cortex-A53 processor @ up to 1.1 GHz System Memory – 512 MB DDR3 Storage – 16GB eMMC flash for OS, SATA 3.0 interface for 2.5″ drives based on ASMedia ASM1092R port multiplier Networking – 1x […]
