Lenovo Project Limitless 5G Laptop and Snapdragon 8cx Benchmarks

Snapdragon 8cx PCMark 10 Application benchmark

Last December, Qualcomm unveiled Snapdragon 8cx processor for laptops, or as the company calls them “always-on always connected mobile PCs”. Only 4G LTE was mentioned at the time, but a few months later it was confirmed that the processor would find its way into 5G always-connected mobile PCs. Qualcomm made two main announcements at Computex 2019 about their new Arm processor for laptops. First, they announced a partnership with Lenovo for Project Limitless, the first 5G PC powered by the Qualcomm Snapdragon 8cx 5G compute platform, and the company released some benchmarks to demonstrate the high performance and long battery life of their solution. Lenovo Project Limitless 5G Laptop The press release did not reveal that much information, but we do know Project Limitless features Qualcomm Snapdragon 8C 5G compute platform with Snapdragon X55 5G modem enabling download speed of up to 2.5 Gbps, and it will be the first 5G laptop available once it becomes available in early 2020. …

PGCPSU is a Tiny LiPo PSU Module (Crowdfunding)

PGCPSU

Last year we wrote about a two dollars USB 18650 battery shield that allows you to easily power your board over USB using a 18650 LiPo battery. But if you need some more flexibility, and extra features such as reverse polarity protection, PGCPSU, which stands for “Pretty Good Cheap Power Supply Unit”, may be worth looking into. PGCPSU key features & specifications: Power Input – micro USB input or pin header for charging (4.7V to 6V max.) Power Output 5V rail providing at least 350mA, and up to 650mA 3.3V rail providing at least 400mA, and up to 800mA Safety Integrated battery protection including reverse polarity protection Over-discharge, short circuit/over-current protection Power Efficiency High efficiency even at low load, important for long battery life Low quiescent current (49uA for the 5V rail + 57uA for the 3.3V rail) Enable/disable pin for the 3.3V rail with selectable default state solder jumper Charging –  Quick charging at up to 1.9A (fully charges …

$100 Reolink Argus 2 is a Wire-Free IP Camera with Optional Solar Panel

Reolink Argus 2 Security IP Cam

This morning I had a look at battery-powered IP cameras since they avoid the hassle of wiring power and/or Ethernet around the house. I could remember I covered Immedia Blink IP camera with up to 2-year battery life back in 2014, and the company did very well since it got acquired by Amazon, and Blink IP security camera is now sold on Amazon US for $99.99 and up. It’s probably one of the best, if not the best options, for low-cost battery-powered cameras but the problem is that they only ship to a limited number of countries. Last year, there was a new entrant with Eufy Evercam outdoor IP camera with up to one year of battery life, but again it’s not easy to purchase from overseas, and the price starts at $279.99 for a single camera system. I also covered a solar and battery powered IP camera made by Wanscam a few years ago, and it could do the …

ESP32 CoinCell is a Tiny, Coin Cell Powered ESP32 Pico D4 Board

ESP32 CoinCell

ESP32 boards can easily be powered by batteries, either through an external USB battery shield, or direct connection to an ESP32 board fitted with battery charger circuitry. But Miek Rankin has done something a bit different, as he designed ESP32 Coincell board based on an ESP32 Pico D4 SiP (System-in-Package) powered by a rechargeable LIR2450 coin cell battery with 100mAh capacity. ESP32 CoinCell board specifications: SiP – Espressif Systems ESP32 Pico D4 Wifi/Bluetooth processor Connectivity 802.11 b/g/n WiFi up to 150 Mbps Bluetooth 4.1 LE On-board antenna Display – 0.69″ OLED display with 96×16 resolution USB – 1x micro USB port for charging and debugging (via CP2102N USB to TTL chip) Sensor – LIS3DHTR accelerometer Battery / Power Supply SE5218ALG-LF 500mA LDO power supply SL4054ST25P LiPo battery charger Socket for  for LIR2450 (3.7V/100Mah battery) Consumption – 0.45mA in sleep mode Dimensions – Small If you don’t connect the battery, the board can still be powered through the USB port. No battery …

Shelly H&T is a Battery Powered ESP8266 WiFi Temperature & Humidity Sensor

Battery Powered ESP8266 Temperature Humidity Sensor

WiFi and long battery life do not usually go hand-in-hand, but as we’ve seen recently, companies have managed to design battery powered WiFi cameras that are said to last up to a year on a charge. So for simpler WiFi devices it should be feasible to last over a year, and that’s what “Shelly H&T” – an ESP8266 based battery-powered WiFi temperature and humidity sensor has apparently achieved, with claims of up to 16 months battery life. Shelly H&T specifications: Connectivity – 802.11 b/g/n WiFi (Wifi 4) Sensor – Temperature & humidity  Battery – 1x CR123A battery good for up to 16 months Dimensions – 35 mm Ø sphere with flat top/bottom  The firmware supports MQTT, and a Rest API, and works with Alexa, Google Home, and home automation suites like OpenHAB, Home Assistant, or Domoticz. The sensor is “open source ready”, meaning you’ll be able to flash your own firmware through the serial interface as shown below. The device …
