Google Titan Security Key Prevents Phishing Attacks

Phising is a social engineering method that aims to trick users into giving their passwords. This can normally be mitigated with things called “brain” and “paying attention”, but since we are all humans mistakes may happen on a bad day. Even Google employees who should be tech savvy fell for the tricks from time-to-time, so Google made employees use 2-factor authentication with a hardware security key since January 2017, and none of Google workers failed for a phising attack since then. CNET was provided with a sample of Google’s “Titan Security Key”, which comes in both USB and Bluetooth/NFC versions, and will be available for sale in Google’s online store within the next few months. The full technical details have not been provided for the key, but we do know Titan Security Keys support FIDO protocol, and are built with a secure element and a firmware written by Google that […]

Google Unveils Edge TPU Low Power Machine Learning Chip, AIY Edge TPU Development Board and Accelerator

Google introduced artificial intelligence and machine learning concepts to hundreds of thousands of people with their AIY projects kit such as the AIY Voice Kit with voice recognition and the AIY Vision Kit for computer vision applications. The company has now gone further by unveiling Edge TPU, its own purpose-built ASIC chip designed to run TensorFlow Lite ML models at the edge, as well as corresponding AIY Edge TPU development board, and AIY Edge TPU accelerator USB stick to add to any USB compatible hardware. Google Edge TPU (Tensor Processing Unit) & Cloud IoT Edge Software Edge TPU is a tiny chip for machine learning (ML) optimized for performance-per-watt and performance-per-dollar. It can either accelerate ML inferencing on device, or can pair with Google Cloud to create a full cloud-to-edge ML stack. In either case, local processing reduces latency, remove the needs for a persistent network connection, increases privacy, and […]

LoStik USB Dongle Adds LoRa Connectivity to any Computer or Linux Board (Crowdfunding)

We’ve covered plenty of hardware with LoRa radio from gateways, to Arduino shields, tracker boards, and mini PCIe cards, but after reading an article on Time4EE this morning, I realized we never wrote about any LoRa USB stick. LoStik – previoulsy LoRa Stick – is an open source hardware USB dongle based on Microchip RN2903 / RN2483 LoRa module, and offered on CrowdSupply for $39. LoStik specifications: USB – USB 2.0 port LoRa Connectivity Microchip RN2903 – 915 MHz for US, Canada, South America and Australia Microchip RN2483 – 868 Mhz for Europe Receiver Sensitivity – down to -146 dBm TX Power – adjustable up to +18.5 dBm Range – up to 15 km coverage in suburban and up to 5 km coverage in urban areas Misc – 2x user LEDs Power Consumption – 140 ma typical TX, 20 ma idle (with power LED) Dimensions – 80 mm x 25 […]

Add a 3.5″ Hard Drive to Your Raspberry Pi with Suptronics X830 Add-on Board

If you ever plan to make your own NAS with an Arm Linux board, the Raspberry Pi board should not be your first choice, as regular readers will already know they are already cheaper and/or better solutions such as NanoPi NEO2 NAS Kit, ODROID HC2, or Popcorn Transformer to name a few. But if you already own one of the Raspberry Pi boards and a 3.5″ hard drive, you considering going with Suptronics X830 add-on boards – also sold under Geekworm brand – instead of a DC powered USB enclosure since it avoids extra cabling and the use of two power supplies. SupTronics X830 board features: SATA connector for 3.5″ SATA drive up to 10TB implemented via USB 3.1 Gen1 to SATA 6Gb/s bridge controller USB 3.0 port to connect to Raspberry Pi board Power Supply Input – 14 to 40V DC input via 5.5/2.5mm power barrel jack (Powers the […]

ASM2362 USB 3.1 Gen2 to PCIe Chip is Designed for USB NVMe SSD Drives

Most USB enclosure or expansion drive are designed with a SATA interface that tops out at 6 Gbp. That’s fine in most cases, but if your host computer comes with USB 3.1 Gen2 SuperSpeed 10 Gbps (SuperSpeed+) port capable of even better performance, ASMedia now has a solution for faster USB drives with their ASM2362 USB 3.1 Gen2 to PCIe NVMe SSD chip. The solution is pretty new, and ASMedia has not setup a product page on their website yet, but they showcased a demo at Computex 2018. In the photo above a Samsung 960 Pro SSD M.2 is connected to another USB board ASMedia – likely based on AS3142 Gen2 xHCI Host Controller – itself connected to a computer with a USB 3.1 Gen2 port. The photo below shows CrystalDiskMark benchmark results comparing ASM2362 USB to NVMe solution to a standard USB to SATA enclosure. While the USB to […]

UM25C is a Better USB Power Meter with built-in Display, Bluetooth, and Android & Windows Apps

Products such as USB Charger Doctor are good way to test your USB chargers or cables, as well as checking the power consumption of USB powered development boards. You just plug them into a USB port, and connect the load, and you’ll see the real-time voltage and current shown on an LED display. Those do the job, but I’ve just been made aware of UM25C USB meter tester that improves a lot on the concept with a dot matrix display capable of showing charts, and Bluetooth connectivity to send the data to Android or Windows devices. UM25C specifications: Display 1.44″ color LCD display 0-5 brightness setting Auto screen off time – 0 to 9 minutes Refresh rate – 2Hz Measurement Range & Accuracy Voltage – 4-24.000V ±0.5‰ + 2digits Current – 0-5.0000A ±1‰ + 4 digits Capacity – 0-99999mAh Energy accumulation – 0-99999mWh Load impedance – 0.8Ω-9999.9Ω Time range – […]
