Intel Speech Enabling Developer Kit Works with Alexa Voice Service, Raspberry Pi 3 Board

We’ve known Intel has been working on Quark S1000 “Sue Creek” processor for voice recognition for several months. S1000 SoC is based on two Tensilica LX6 with HiFi3 DSP, some speech recognition accelerators, and up to 8x microphones interfaces which allows it to perform speech recognition locally. The solution can also be hooked to an application processor via SPI, I2S and USB (optional) when cloud based voice recognition is needed. Intel has recently introduced their Speech Enabling Developer Kit working with Amazon Alexa Voice Service (AVS) featuring a “dual DSP with inference engine” – which must be Quark S1000 – and an 8-mic array. The kit also includes a 40-pin cable to connect to the Raspberry Pi 3 board. Intel only provided basic specifications for the kit: Intel’s dual DSP with inference engine Intel 8-mic circular array High-performance algorithms for acoustic echo cancellation, noise reduction, beamforming and custom wake word […]

Sonoff Wireless Switch Family Gets a $3 IP66 Waterproof Enclosure

ESP8266 powered ITEAD Studio Sonoff wireless switches have been popular because they are inexpensive, highly customizable thanks to work from the community leading to open source projects such as ESPurna and Sonoff-Tasmota, and come fully packaged so you don’t need to make your own case for it. That works well for indoor projects, but if you needed to control outdoors lights, gate, water pump, etc… you had to protect the device from humidity/rain. That may not be necessary anymore as the company is now selling Sonoff Basic with an IP66 waterproof enclosure for $7.75, or the case only for $2.90.Sonoff waterproof case: Ingress Protection Rating – IP66 Material – PC V0 Dimensions – 132.2 x 68.7 x 50.1mm (See details) Weight – 145.0g IP66 rating is not suitable for prolonged immersion, but it should be good to protect against rain or high humidity. The box ships with two standardized PG7 […]

RedRat-X IR, Bluetooth & RF4CE Box Can Control Multiple TVs and Set-top Boxes

IR blasters can be used to control multiple IR devices through infrared, or other interfaces, for example DVR can use such device to change the channel of a set-top box just before recording. RedRat-X is one of those devices for automating control of TVs, STBs and other infrared equipment, but it’s quite more versatile, as beside its built-in IR blaster, it adds 3 IR outputs were you can connect your own IR transmitters, as well as USB and Ethernet for remote controls. Furthermore, it can also take add-on modules to emulate Bluetooth and RF4CE remote controls. RedRat-X specifications: IR blaster via the front of the unit. 0 mA to 250 mA in 100 steps. 3x plug-in IR jack sockets which can be used in two modes: Current mode (default): For use with plug-in IR flashers – 0mA to 100mA in 100 steps. Voltage mode: To interface to IR distributions systems, […]

Industrial Shields Industrial Panel PCs are Based on Raspberry Pi, Banana Pi, or HummingBoard

Boot&Work Corp., S.L. is a company based in Catalonia that sells industrial automation electronic devices under “Industrial Shields” brand. What makes their product noticeable is that they all appear to be based on maker boards such as Arduino or Raspberry Pi. The company offers various Arduino based PLC modules with or without Ethernet that can be controlled with 10.1″ industrial grade panel PCs based on ARM Linux development boards. Currently three sub-families are available: HummTOUCH powered by Solidrun HummingBoard-i2 NXP i.MX 6Dual Lite board BANANATOUCH with either Banana Pi M64 (Allwinner A64 quad core Cortex A53) or Banana Pi M3 (Allwinner A83T octa core Cortex A7) TOUCHBERRY with Raspberry Pi model B or Raspberry Pi 3 model B Beside the different processors, the 10.1″ Panel PCs share some of the same specifications: Display – 10.1″ resistive multitouch LVDS, 315 nits, 170° viewing angle, 1280×720 resolution Video Input – MIPI CSI […]

Review of Sonoff B1 Smart RGB Light Bulb – Part 2: Sonoff-Tasmota Firmware

I’ve already reviewed Sonoff B1 light bulb using the stock firmware combined eWelink app for Android, and as promised in the first part of the review, I’ve also tested the ESP8285 based WiFi light bulb with Sonoff-Tasmota open source firmware, and report my findings in this new post. Before we can play with the new firmware, we need to install it, and I’ve just explained how to upgrade Sonoff devices to Sonoff-Tasmota firmware either using some soldering skills and a USB to serial board, or some network configuration skills and perform an OTA update using ITEAD Studio/eWelink original firmware update mechanism. So for this part of the review, I’ll assume we have just freshly update the light bulb with Sonoff-Tasmota using the binary images released by the developer. First, you’ll need to find the IP address of the light bulb with your router or tools like nmap or arp, and […]

Upgrading Sonoff Stock Firmware to Sonoff-Tasmota – USB to Serial, and OTA Update Methods

This post was initially supposed to be part 2 of Sonoff B1 light bulb review, where I would have explained how easy it was to use OTA mechanism to update to Sonoff-Tasmota open source firmware, and shortly show about its features and capabilities. However, it took me over 10 hours to make that work, mostly due to misunderstand in the documentation, and time spent to configure routers. I also failed the first time with Sonoff B1, so I used the serial console method, and instead managed to use SonOTA method with Sonoff POW switching from stock firmware to Sonoff-Tasmota without having to solder or tear down anything. Updating software with a USB to Serial Board Using a USB to serial board is the most common method to switch from stock firmware to open source firmware such as ESPurna or Sonoff-Tasmota in Sonoff devices or other ESP8266 based devices. It’s quite […]

Sonoff B1 Smart Light Bulb Review – Part 1 : eWeLink Android App and Teardown

ITEAD Studio has a popular family of home automation devices call Sonoff with WiFi switches, smart sockets, RF to WiFi bridges and so on. All WiFi devices are based on Espressif ESP8266 or ESP8285, and while the company provide a stock firmware working with eWelink app, at least two communities have formed around Sonoff and other similar devices providing two open source firmware alternatives: ESPurna and Sonoff-Tasmota. The company has sent me Sonoff B1 smart RGB light bulb for review. Today, I’ll check out the light with eWelink app for Android, and do a teardown, before trying one of the open source firmware in the second part of the review. Sonoff B1 Unboxing Some Chinese products come in a blank cardboard boxes, but Sonoff’s light bulb comes with in a nice looking retail package that would look good on store’s shelves. One of the side lists the specifications with an […]
