Helium Hotspot LoRaWAN Gateway also Earns Cryptocurrency

We covered MatchX M2 Pro LPWAN Crypto-miner yesterday, and at first, I really thought that combining LoRaWAN gateway with cryptocurrency mining was really just a gimmick. But after talking with others, I found out that MXC Foundation HashDash used with the MatchX gateway was not the only such solution, and I was introduced to Helium Hotspot. A Helium Hotspot is a LoRaWAN gateway that also allows you to earn HNT cryptocurrency, and it could more than just prove a way to fund the deployment of public LoRaWAN networks, as as we’ll see below some people or companies are making some serious money, while others not so much. A DIY Helium Hotspot can also be made from a Raspberry Pi 3/4 and a RAK2245 Pi HAT. Helium Hotspot key features and specifications: SoC – Quad-core Arm Cortex-A53 application processor System Memory – 1GB RAM Storage – 64GB Storage Connectivity Ethernet Dual-band […]

Folding@Home ARM64 Linux Beta Release for COVID-19 Vaccine Research

A few months ago, we reported that Rosetta@Home supported 64-bit Arm SBC’s and Servers in the Fight against COVID-19. But Folding@home did not support Arm hardware just yet, but thanks to work from Neocortix, Linaro, Arm, miniNodes, and Packet.com, we now get support for Folding@home on ARM64 meaning you can help researchers studying SARS-CoV-2 virus and help them develop a COVID-19 vaccine with Raspberry Pi 3/4 boards, or other 64-bit Arm SBC’s and servers. The solution relies on Neocortix Cloud Services Platform allowing the unused capacity of large numbers of individual mobile phones or other connected nodes to be harnessed into a single, unified computational engine. The very first application that made use of the platform was Neocortix PhonePaycheck were users get paid to let businesses perform calculations on their phones at night while charging and connected to WiFi. That way users of premium phones like Galaxy S10 or S20 […]

How to Fix Unreliable USB Hard Drives, Stalled Transfers in Linux

Last June, I reviewed a Ryzen Embedded SBC with Windows 10, and the USB hard drive I normally use for review had all sorts of problems including very slow speeds and/or stalled transfers but no error messages. Last week, I tried again by installing Ubuntu 20.04 on the same Ryzen Embedded SBC, and the USB hard drive had troubles again, so just assume there were some hardware incompatibility issues between the SBC and the drive, and there may not be a fix or workaround. Sometimes, it’s indeed a hardware issue with the drive getting too many bad blocks, and if that’s the case, and the drive is still under warranty you can return it and get a fresh new (or refurbished) drive for free. But that drive was still working with my laptop getting around 100MB/s. So I ran out of ideas until numero53 commented he had similar problems with […]

Zero Terminal V3 is a Modular Raspberry Pi Zero W Powered HandHeld PC

Zero Terminal V3 Raspberry Pi Zero W Handheld

Hardware hacker NODE has created a slick handheld Linux PC based on the Raspberry Pi Zero W board. About the size of a thick smartphone, Zero Terminal V3 also includes a touchscreen display, a built-in battery, a USB Type-A port, and a microSD card slot. The keyboard found in previous iterations of the Zero Terminal is gone, as the new version focuses on modularity thanks two 40-pin sockets that connect to the GPIO pins, video output, camera connector, USB ports, power indicators, etc… in order to allow people to create and add custom backpacks to change the functionality as needed. Zero Terminal V3 specifications: SBC – Raspberry Pi Zero W with Broadcom BCM2735 ARM11 processor, 512MB RAM, MicroSD card socket, WiFi 4, and Bluetooth 4.0 Display – 5.5″ 1080p AMOLED touchscreen display bought on Waveshare and designed for Raspberry Pi 3/4, but NODE designed an adapter for RPi Zero.
