Why Do UL and CE Certifications Matter For Anything That Connects to the Mains (110V/220V) ?

I’ve been featuring a few cheap automation appliances such as Orvibo Wiwo S20 WiFi smart socket or lately Sonoff & Slampher WiFi and RF switch and lightbulb adapter, and people mentioned that Wiwo S20 socket was unlikely to be compliant with CE up to 10A since it lacked the ground pin, and I was also informed that Sonoff & Slampher was probably not compliant with UL certifications. Why does not matter? The picture below may give a clue… UL and CE certifications are used to make sure the device complies with safety regulations, and in some case make also improve reliability, as in UL compliant power supplies will feature inexpensive TVS device to protect against thunder. And if you think you are covered because you have an house insurance, it’s quite likely it will be void if the on-site expert find a non-compliant device on the site of the fire. […]

FTDI NerO is an Energy Efficient Arduino UNO Compatible Board That Can Handle Higher Loads (Crowdfunding)

FTDI found out that the original Arduino UNO R3 boards had issues handling higher loads with 9V and 12V power input being limited to about 800mA and 300mA respectively before the voltage of the 5V regulator drops, so they decided to make their own supporting up to 1A. NerO board specifications: MCU – Atmel ATMega328 MCU @ 16MHz with Optiboot bootloader I/Os 14 Digital I/O Pins including 6 PWM outputs 6 Analog Inputs USB – micro USB port for programming using FTDI FT231XS USB UART interface (4) Misc – Status and PWR LEDs, on/off switch Power Supply – 7V to 20V ( 9V or 12V recommended ) via power barrel or VIN pin. 5V switching regulator. Dimensions – UNO R3 form factor FCC/CE certified The board is manufactured in Europe by MikroElektronika, a company which I started the hear about more and more, especially since they’ve launched their mikroBUS standard […]

LG Rolly is a Bluetooth Keyboard that Folds into a Stick

There are already some flexible Bluetooth keyboards that you can roll into your bag or pocket after being done typing on your smartphone or tablet, but LG is about to launch Rolly Keyboard, a solid Bluetooth keyboard for mobile device that can be rolled into a stick, which should may be sturdier than flexible keyboards, and it can also hold a smartphone or tablet in upright position with a display of up to 10″ in size. LG’ latest keyboard (model KBB-700) is comprised of 17mm keys – a standard keyboard comes with 18mm keys – arranged into four rows, that can be folded into a stick as shown above. The company also claims the keyboard offers “satisfying tactile feedback not found on flexible silicone keyboards”. The keyboard is powered by two AAA batteries supposed to last about 3 months during typical use, and pairing over Bluetooth 3.0 occurs automatically to […]

ARDHAT adds Arduino Shield Compatibility, an ISM Band Radio to Raspberry Pi and ODROID-C1 Boards (Crowdfunding)

NinjaBlocks created Pi Crust add-ons board adding a 433MHz radio and Arduino compatibility to the Raspberry Pi Model A & B a few years ago, but the product has since been removed from their store. But a startup called ubIQio has now created a similar product compatible with Raspberry Pi Model A+, B+ and B2, as well as ODROID-C1 which also comes with a 40-pin R-Pi header. The ARDHAT board is a HAT compatible add-on board with an Atmel MCU, Arduino headers, as well as an optional long range mesh ISM radio (433, 868 and 915 MHz) and various sensors. There are four versions of the board: Basic Ardhat, Ardhat-I, and Ardhat-W and Ultra, which share the following specifications: MCU – Atmel MCU @ 16MHz Headers and I/Os Arduino compatible header accepting 5V Arduino shields 12 ch PWM O/P, 6 ch analog I/P Real-time Clock Programmable Power/Navigation combo switch Programmable […]

PiJuice Battery HAT Module for the Raspberry Pi Boards Comes with an Optional Solar Panel (Crowdfunding)

The Raspberry Pi is a low power board that can be powered a few hours or a few days with batteries, and the easiest solution is probably to use a USB power bank connected to the micro USB port of the board, but the solution is not really integrated. That’s where PiJuice comes into play. It’s a HAT compatible module that connects nicely to the latest Raspberry Pi boards with 40-pin header (A+, B+ and B2), and include a 1,400 mAh battery that can be used as UPS (Uninterrupted Power Supply), an RTC, and more. Key features of PiJuice HAT: 1400 mAh  Lipo battery, good enough to last up to 24 hrs in constant use. 5,000 mAh batteries are also said to be supported. Full UPS (Uninterrupted Power Supply) solution Integrated RTC (Real Time Clock) On board intelligent on/off switch Low power deep-sleep state with wake on interrupt/calendar event On […]

What Do You Do with Your Old Devices and Boards?

New and faster processors and products come out regularly, and prices have come down so much that people are likely to discard old devices, or let them collect dust, as new devices can be bought for half the price you bought your now sluggish single or dual core mini PC, remember CX-01?, last year or two. However, people may not like to through perfectly usable product by principle, while others may be concerned by the pollution effects of our consumerism, and craze for the latest gadgets. There must surely things that can be done instead of simply trashing old devices. I’ll give some ideas mostly for mini PCs, but since a group of person is smarter than one only, I’m sure I get some interesting input. Give your old devices to friends of family. Downside: they may never used it themselves either. Sell your device on Ebay or other websites. […]
