Raspberry Pi 3 Model B and Rock64 1GB SBCs Promotions

Raspberry Pi 3 Model B Free microSD Card

Ameridroid has some promotions for two of the most popular single board computers on the market. The Raspberry Pi 3 Model B (not B+) is now offered for $33.95, or $32.95 with CNXSUPPORTER1 coupon, with a free 16GB class 10 micro SD card pre-loaded with NOOBS. The company also discounted Rock64 board (1GB RAM model), with the same form factor as Raspberry Pi 3 Model B, but a faster Rockchip RK3328 processor, and high-speed interfaces like USB 3.0 and Gigabit Ethernet, making it one of the best alternatives to Raspberry Pi 3 board. You can now get it for $24.95, a discount of $5 compared to the normal price on Ameridroid. $24.95 also happens to be the price the board is sold on Pine64, but you may save on shipping depending on where you live. You’ll also be able to save a bit more by using one of the following […]

HKCam is a Raspberry Pi Zero W based DIY HomeKit IP Camera

HKCam Raspberry Pi HomeKit IP Cam

HKCam is an IP camera based on Raspberry Pi Zero W board and compatible with any HomeKit apps. The developer, Matthias Hochgatterer, did not make the hardware himself, and instead purchased a Raspberry Pi Zero W + camera kit sold for around $30 on Aliexpress. His main work was to design a 3D printed case and write the software running in the camera, as well as his own Home 3 smart home automation app for iOS compatible with HomeKit. The only hardware needed is the Raspberry Pi Zero W with a power supply, the official Raspberry Pi camera module with is flat cable, and a microSD card, so you could also get those locally instead of purchasing them from Aliexpress. The firmware is based on Raspbian, FFmpeg to access the camera stream, as well as hc, a lightweight framework to develop HomeKit accessories in Go. You’ll find the documentation, source […]

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

Node Mini Server V2 3D View

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 […]

E-ALE is a Free & Open Source Linux Training Program for Embedded Engineers

E-ALE official hardware kit

As I wrote about the Embedded Linux Conference 2019 schedule a few days ago, I found out one of talk planned to use E-ALE hardware kit for the session. I had never heard about this kit, but a quick search led me to e-ale.org website which explains E-ALE stands for Embedded Apprentice Linux Engineer. The training program is made for embedded engineers with experience designing firmware for microcontrollers, but now need to transition to embedded Linux. Training only happens in-person (no webinar) at existing Embedded Linux conferences and is comprised of 8 to 9 seminars over 2 to 3 days. It usually starts with a presentation on one subject, followed by lab time to practice the relevant learned skills. The training takes place on the E-ALE kit at each conference, but it does not refer to a specific hardware platform. In most conferences, the PocketBeagle and BaconBits add-on board are […]

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 […]

BB-400 Neuron Edge Dual Ethernet Industrial Controller Combines Raspberry Pi CM3+ and Arduino MCU

bb-400 neuron edge industrial controller

While the Raspberry Pi boards are mostly promoted as tools to teach STEM to kids and adults alike, they have found their way in a fair amount of industrial products, including ModBerry M500 industrial computer, Janz Tec emPC-A/RPI3 industrial embedded controller, and Kunbus RevolutionPi RevPi Core among others. There’s yet another option with Brainboxes BB-400 Neuron Edge industrial controller that was announced last year with Raspberry Pi Compute Module 3, but recently got an upgrade to Raspberry Pi Compute Module 3+. The controller features two Ethernet ports and also includes an Arduino compatible microcontroller to control the system’s eight configurable digital inputs and outputs. BB-400 Neuron Edge industrial controller specifications: SoM – Raspberry Pi Compute Module 3+ with Broadcom BCM2837B0 quad-core , Cortex-A53 processor @ 1.2GHz, 1 GB LPDDR2, 32GB eMMC Flash storage MCU – Unnamed Microchip Atmel Arduino compatible microcontroller Connectivity Ethernet Uplink Port – 1x RJ45 jack, 10/100Mbps […]
