Your Smartphone Could Become The Brain and Touchpad of Your Laptop (Dock)

Mobile desktop convergence is likely to happen sometimes in the next few years, at least for some users, when your smartphone will be the brain of your laptop or desktop computer. So far I imagined the smartphone would fit into a dock powering the phone – potentially wirelessly – and connects it to a large monitor, extra storage, and a keyboard and mouse. But based on a patent filled by Apple, it may also take another form: a laptop dock where your smartphone fits right where the touchpad is supposed to be. The patent for an “ELECTRONIC ACCESSORY DEVICE” describes “various embodiments of systems and methods for providing internal components for portable computing devices having a thin profile. More particularly, the present application describes an electronic accessory device available to extend and expand usefulness of a portable computing device”. The patent does not appear to describe the interfaces, but presents […]

MAXOAK K2 is a 50,000 mAh Power Bank Designed for Laptops, Cameras and Mobile Devices

Most of the time I receive samples by courier 3 or 4 days after the company sends it, but sometimes I’m being sent devices over airmail which may take 2 to 3 weeks, or even more. Today, I received such a parcel with no clear description on the package, and a relatively heavy blank carton box. But I remembered somebody told me they’d send a large power bank for laptops. Could it be it? Sure enough. The power bank is called MAXOAK K2, and claims to offer a 50,000 mAh capacity using a Polymer Li-on battery. All connectors and buttons can be found on one side with the DC jack, four charging/capacity LEDs, the power button, 20V/3A and 12/2.5A barrel outputs, and four USB ports with 5V/2.1A or 5V.1.0A output. Most of the laptops I’ve used were powered by 19V or 19.5V adapters, so I’m not sure it’s safe to […]

Intel to Launch Optane Memory M.2 Cards for Desktop PCs Next Month for $44 and Up

Intel launched their first Optane SSD based on 3D Xpoint technology for the enterprise/datacenter market last week, and now the company has announced 16GB and 32GB consumer grade Optane memory will start selling in April starting at $44. The cards will follow M.2 card (80mm) form factor, use a dual PCIe NVMe 3.0 interface, and currently only works with Optane compatible motherboards with 7th generation Intel Core processors. Intel promises boot times that are twice as fast, 28% better overall performance, and 65% faster game level loads thanks to vastly improved random I/O performance. We can see some of the specs for both cards on Intel website. I reproduced some of the performance reliability data in the table below. 32GB Optane Memory 16GB Optane Memory Sequential Read (up to) Up to 1350 MB/s Up to 900 MB/s Sequential Write (up to) Up to 290 MB/s Up to 145 MB/s Random […]

Rikomagic R1 Android Projector Review – Part 1: Unboxing and Teardown

Rikomagic R1 Android mini projector runs Android 4.4 on Rockchip RK3128 quad core processor, and the company sent me a sample for review, so today I’ll first do an unboxing, and partial teardown, before testing the projector in more details in the second part of the review. Rikomagic R1 Projector Unboxing The projector comes with a white package marked RKM R1. The bottom of the package indicated its unsurprisingly based on Texas Instruments DLP technology with a LED light, and is equipped with a touch panel and a battery. More importantly, there’s a QR code that links to R1 Setup Guide, which for once will be useful, as this device has some unique features. The projector ships with a 5V/2.5A power supply, an IR remote control, a HDMI cable, a tripod, and an adapter to make the interface between the projector box and the tripod. The top of the device […]

Linux based iWave Systems OBD-II Dongle Comes with 4G LTE and GPS

OBD-II dongles that you connect to your car’s OBD-II port have been around for several years, but they were initially simple devices with USB or Bluetooth connectivity that you control with your smartphone or computer. More recently we’ve seen more complex OBD-II head-up-diplays, and boards such as Macchina M2 open-source hardware OBD-II board that takes various XBee modules for 4G, Ethernet, WiFi, Bluetooth, GPS, and so on. iWave Systems, a company better known for their system-on-modules, has now unveiled their own OBD-II dongle with NXP i.MX 6UL processor running Linux, and integrating 4G LTE and GPS by default. iWave Systems OBD-II dongle specifications: Processor – NXP i.MX 6UL ARM Cortex-A7 processor @ 528/696MHz Memory – 256 MB DDR3 (Optionally upgradeable to higher capacity) Storage – 256 MB NAND Flash (optionally upgradeable to higher capacity). Connectivity – Built-in 4G Modem with antenna, optional WiFi & Bluetooth 4.0 LE module Positioning – […]

Karl’s Home Automation Project – Part 3: Adding Light Detection to a Motion Sensor

This is the 3rd part of my Home Automation light project. In the first part, I wrote about basic setup with basic Sonoff Wifi MQTT switches and setting them up. In the second one, we added some 433 MHz motion sensors and a 433 MHz to MQTT bridge. And finally in part 3, we are going to modify the 433 MHz motion sensors to only work when it is dark in the room. Motion Sensor The motion sensor I linked in part 2 is run by a common chip called a BISS0001. We are interested in pin 9. If voltage is below .2v it will not trigger a motion. This solves the problem discussed in part 2, when we have a gloomy day or if blinds are closed etc. By adding an GL5537 LDR (Light Dependent Resistor) shown as R3 in the diagram above, you will achieve the desired effect.
