It’s now fairly easy to find the hardware to create WiFi or Bluetooth controlled relays, but you usually have to design your own enclosure and Android app, and if you’d like something that’s ready to use out of the box TinySine wireless relays such as TSRB430 (Bluetooth) or TSRW430 (WiFi) might be an interesting option. There;s also a version with USB control. TSRB430 / TSRB430 / TSRU430 specifications: 4x Omron G8P 30A/250VAC | 20A/28VDC relay; SPST-NO (normally open) types. Connectivity – XBEE module either: Bluetooth Bee module based on CSR BC417143 Bluetooth 2.0 chipset Roving Networks WiFi Bee module with 802.11 b/g radio USB Bee module with a CP2102 USB to UART chip Power Supply – 12V/1A via 2.1mm jack with positive core polarity Dimensions – 122mm x 87mm x x 31mm (board) There are also versions with 2 and 8 relays. I kind of wish they had models taking 220V AC input instead […]
Vinclu Gatebox is an IoT Gateway using a Hologram Girl as the User Interface
Let’s face it, home automation or IoT gateways are just boring cubic, rectangular or cylindrical boxes without soul that just transmit packets and gather data between different devices. But don’t despair, as Vinclu, a Japanese start-up, has come up with Gatebox an IoT gateway with a virtual girl, named Hikari Aizuma, that welcomes you back home, turns on the TV on request, wakes you up in the morning and gives the day’s weather forecast, and more! The product is still in development, and we don’t known many details, but the Gatebox is said to uses video projection technologies and various sensors, and you’ll be able to select other characters. The company has raised 90 million JPY (~$770,000 US) and is currently recruiting engineers to complete hardware and software development. The device is expected to be launched at the end of the year via a crowdfunding campaign. You can watch the concept […]
Review and Teardown of Simplelink Self-Powered Power Switch
After I wrote about SimpleLink Batteryless power switch and receiver, the company decided to sent me a kit to try out by myself. So in this review, I’ll checkout the kit, install a demo to show how it works, and finally have a look at the internals. The kit include a power cord with a US plug and a holder and corresponding light bulb that you need to connect to the corresponding red and blue wire of the receiver (white cylinder), and you can control with the green power battery-less switch. Two 3M double face stickers are also included for the receiver and switch, as well as a strap for the switch, a screw set for either the light holder or receiver, and a user’s manual shown below. Installation is pretty self-explanatory, and you just need to connect the blue and red cables to the input (mains) and output (light) […]

SimpleLink Battery-less Power Switch Leverages RF & Energy Harvesting Technologies
SimpleLink may be the name used by Texas Instruments for their wireless MCU family, but there’s also a Chinese company called SimpleLink Technology that develops wireless smart home solutions including battery-less power switches that communicate over sub GHz band to receivers using energy harvested from pressing the button(s) on the switch. They have different models with 1 to 4 buttons, and round and square shapes. Let’s have a look at SIM1010-K1 specifications: Switch Type – Push-Button; operating force: 7N; typical total travel: 4mm Number of Keys – 1 gang Power Mode: Self-Powered Control Distance – Up to 30 meters indoor (works though walls), 100+ meters outdoor Frequency Bands – 433/315/868/915MHz Lifetime – >200,000 times Connectivity – SimpleLink (most probably entirely unrelated to TI SimpleLink); +10dBm Tx power Operating Temperature: -25~70℃ Operating Humidity: 0~95%RH Dimensions – Ф 70 x 15.5 mm Weight – 44g That self-powered wireless switch will prevent the […]
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. […]
PINE A64 Development Board Kickstarter Campaign is Up
As previously announced, PINE64 $15 64-bit ARM Linux computer was due to launch on December 9, and the Kickstarter campaign is now up, and the shipping costs are $7 to the US, and $12 to the rest of the world. The name have changed to PINE A64 and PINE A64+ since the first announcement, but the specifications have mostly not changed for th two boards with an Allwinner quad core Cortex A53 processor, 512MB to 1GB RAM, a micro SD slot for storage, Gigabit Ethernet, HDMI 1.4, USB ports, and some other expansion headers for I/Os, displays or cameras. The PINE A64+ however now has an option for 2GB for $29, and we’ve got a bit more information about optional modules and accessories: Wireless module with WiFi and Bluetooth adapter Zwave adapter 7″ LCD touchpanel (PINE64+ only) Dry contact I/O board 5MP MIPI CSI camera Various sensors Various remote controls […]
Sonoff & Slampher are $5 RF and WiFi Smart Switches and Lightbulb Adapters (Crowdfunding)
ITEAD Studio has launched two new low cost home automation products with Sonoff smart switch, and Slampher smart E27 light bulb adapter both supporting control via WiFi and your Android smartphone, or 433MHz with a simple remote control, while still retaining the capability to control your electrical appliances and lights with a manual switch. Installation is pretty easy, and safer than some other products like Semlamp. Sonoff – You simply need to cut the cable to your appliance, and insert two wires into the IN part, and the other two wires into the OUT part. Turn if on, and add it to the app if you are going to use a smartphone Slampher – Remove your light bulb from its current socket, screws the bulb to Slampher, and put it back into your socket. Register the light in to the app and your done. Both devices will send data to […]
