RisingHF IoT Discovery is a LoRaWAN Evaluation Kit for Raspberry Pi

There are many current and upcoming long range low power wireless protocols for the IoT, but this morning I learned that South Korea launched a LoRa network (aka LoRaWAN), after another launch in the Netherlands earlier this year. While there are also some LoRa hobbyist kits such as LoraONE and LoPy being worked on, I decided to look on Aliexpress, but only got two products were listed: a LoRaWAN temperature and humidity sensor, and a LoraWAN USB modem. Both of them are made by a company called RisingHF. Among the products offered by the company, there’s a potentially interesting development kit called RisingHF IoT Discovery with the following components: 1x Raspberry Pi board 1x RHF0M301 LoRa Gateway based on Semtech SX1301 1x RHF4T002  adapter for Raspberry Pi and RHF0M301 1x RHF3M076 LoRaWAN USB AT Modem End point to connect to computer. It operates at 434MHz, 470MHz,868MHz, and 915MHz 3x RHF76-052 […]

Have US Customs Declared War on TV Boxes (and mini PCs)?

Customs are useful to make sure illegal or dangerous goods don’t reach customers, and they also “protect jobs” or “special interests” by applying tariffs to imports. If you’ve ever purchased goods out of your country or economic zone, the experience can range from flawless (no duties), to annoying (paying some taxes), up to really frustrating and depressing, if customs decide to have a closer look to your imported item. Most the time I don’t have any problems, especially since I try to be careful to stay below the limit (~$30 here) sometimes splitting my orders, a few times I have to pay custom duties and VAT, and once I got a call from UPS telling me my $100 mini PC was kept by customs (not sure why), and that the total cost to it get was unknown, but it will be at least $150 for handling and taxes, and sending […]

WiReboot is a Watchdog Device Rebooting Your Router if the WiFi Connection is Lost (Crowdfunding)

Routers are usually pretty stable devices, but sometimes they still hang, and I think I must reboot my router about 2 to 3 times a year as I lose (Ethernet) connectivity. I’m usually at home, so it’s not really an issue as I can just walk a few meters to manually reboot the router.  But if you are often on the go, and have a few WiFi devices such as smoker alarms, smart lights, and other home automation products that you may want to control over the Internet, if WiFi goes down nothing works. Luckily there’s a solution: WiReboot, a small device powered by ESP8266 that will check your WiFi and Internet connection, and automatically restart the router if it fails.Key features of WiReboot: ESP8266 module for 802.11 b/g/n WiFi connection USB – 1x USB input port to connect your router power supply, and 1x USB output to connect to […]

Review of Vorke V1 mini PC Powered by Intel Celeron J3160 Processor

After checking out Vorke V1 mini PC hardware in the first part of the review, it’s now time to publish the review starting with system information, benchmarks, and user testing. The device competes with similarly priced devices based on Intel Atom x7 processor such as Voyo V3 and Beelink BT7, so I’ll also include some comparisons to those in the review. Setup and System Information I connected USB keyboard and mouse, an Ethernet cable, HDMI and VGA cables to check dual display support, as well as the power supply. I did not connect my USB 3.0 hard drive since, I’ve already fitted the mini PC with an internal 1TB hard drive. Pressing on the large power button on the top of the device will boot it, and after a few seconds, you’ll get to go through Windows 10 setup by first accepting the EULA. The next steps are Custom or […]

Raspberry Pi Zero Based Google’s Project Bloks Aims to Teach Programming to Young Children

Visual programming development tools such as Scratch or Blockly are now becoming more popular to introduce school children to programming, and Google Research is now working on bringing the software visual programming concept to physical blocks “programming” though Project Bloks targeting younger children who may not be able to write or read yet. It might also help older children grasping programming concepts faster than when programming by typing on a keyboard. Project Bloks is comprised of three main hardware components connected together: Pucks – Those are the buttons, dials, switches, and other inputs from the project. Pucks have no active electronics, and even a piece of paper with some conductive ink could be a Puck. Base Boards –  They read a Puck’s instruction through a capacitive sensor, and forward a Puck’s command to the Brain Board.  Each Base Board is also fitted with a haptic motor & LEDs, and can […]
