Cambrionix PowerPad 15S is a 15-Port USB Hub with 2.1A Output, Control API, Serial Console, Power Consumption Monitoring

Many development boards are powered over USB, usually via a micro USB ports, and if you have one board, you’d just use a 5V USB adapter with the right amperage, and it will work fine as long as you have a low resistance USB cable (AWG20 cables recommended for higher loads).  But when you start to running multiple boards using power strips with USB adapter start to take space, so USB hubs are much more convenient. However, you need to find one that delivers enough power, is reliable, and possible allows per port power control. The guys at LAVA (Linaro Automated Validation Architecture) are using a lot of boards to validate software developed by Linaro and their members, with the boards having to run 24/7, and they had various misfortunes with USB hubs, but as Dave Pigott reports they’ve now found that USB hub of their dream with a 15-port […]

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.

Dell Edge Gateway 3000 Series Are Powered by Intel Bay Trail-I SoCs for Automation, Transportation, and Digital Signage

Dell has recently introduced Edge Gateway 3000 series with three models powered by Intel Bay Trail-I processor, running Ubuntu Core 16 or Windows 10 IoT, with each model targeting respectively general-purpose automation, transportation & logistics, and digital signage and retail. The specifications for the three models can be found in the table below. Dell Edge Gateway 3001 Model for General-Purpose Automation Dell Edge Gateway 3002 Model for Transportation & Logistics Dell Edge Gateway 3003 Model for Media & Retail Kiosks SoC Intel Atom E3805 dual core processor  @ 1.33 GHz (3W TDP) Intel Atom E3815 single core processor @ 1.46 GHz with GPU @ 400 MHz (5W TDP) System Memory 2 GB DDR3L-1066 Storage 8 or 32 GB eMMC flash Industrial-grade Micro-SD card: 8GB / 16GB / 32 GB / 64 GB Connectivity 1 x 10/100 Fast Ethernet (RJ-45) with PoE (15.4W) WiFi 802.11 b/g/n Bluetooth 4.0 LE Optional ZigBee […]

$12 AI Light ESP8266 based WiFi RGB Light Bulb Supports MQTT via ESPurna Open Source Firmware

AI-Thinker is famous in the maker world for their ESP8266 modules, but they’ve also recently launched a WiFi RGB light bulb that sells for about $12.5 and up on eBay and Aliexpress. Some people noticed, and bought samples online, including Xose Pérez (aka Tinkerman), ESPurna open-source firmware developer, who could confirm ESP8266 was used in the light bulb, did some investigations, and eventually added the light bulb into ESPurna, which means it can be managed using MQTT or a web interface. AI Light looks very similar to Philips Hue, but comes with WiFi instead of Zigbee. AI Light “M1636” key features: RGBW LED E27 bulb with 16.7M colors Connectivity – 802.11 b/g/n WiFi Encryption – AES Voltage Range – 110-240V LED Power – 5 watts WiFi Power Consumption – ≤0.3W Temperature Range – -5~45degree Humidity – ≤80% Certifications – FCC, CE, ROHS If you’re going to use the stock firmware, […]

Karl’s Home Automation Project – Part 2: 433 MHz / WiFi MQTT Bridge, Door & PIR Motion Sensors

Karl here again for part 2 of my home automation project. We will be looking at how to automate your lights based on time of day and motion. In the first part we setup Home Assistant and uploaded firmware to basic Sonoff Wifi switches. Today we will setup a 433 MHz to MQTT bridge and some sensors. 433 MHz Depending on your country 433 MHz is an open frequency to use to communicate with. There are hundreds of different types of devices that use 433 MHz to communicate information. We will be focusing on 2 today from Gearbest: WMS07 motion sensor (left) and WDS07 door/window sensor (2 parts, right). I am not taking the door/window sensor apart, since it is super basic, but I’ve included some photos of the PIR motion detector. 433 MHz Bridge While contemplating how to get presence on a per room basis I ran across this […]

Karl’s Home Automation Project – Part 1: Home Assistant & YAML, MQTT, Sonoff, and Xmas Lights

Karl here. I am here to write about my home automation project. First thing I want to say is that I am very cost conscious and I don’t mind putting in extra effort into the setup of things to keep costs down. I did invest a lot of time and had to do a lot of reading to get my project going. It took while and I received a lot of groans from my wife while testing. I am still in the process of tweaking things. I started watching a series of videos on YouTube from Bruh Automation. He introduced me to Home Assistant. It got me really excited. He uses a Raspberry Pi as a server but I already had a Wintel Pro CX-W8 Smart TV Box which I use as a server. I run 3 Minecraft Servers, Emby Server, iSpyConnect DVR (2 IP Cameras), Unifi wifi controller, and […]

22€ Olimex ESP32-EVB ESP32 Development Board Features an Ethernet Port and Relays

We already have a good choice of ESP32 development boards, but none of the ones I’ve seen make use of the Ethernet MAC interface found in Espressif ESP32 SoC. Olimex has changed that with their ESP32-EVB featuring ESP32-WROOM32 module as well as one Fast Ethernet port and two relays. Olimex ESP32-EVB specifications: Wireless Module – ESP32-WROOM32 module with 802.11 b/g/n WiFi and Bluetooth LE Wired Connectivity – 10/100M Ethernet RJ45 port External Storage – micro SD slot Relays – 2x 10A/250VAC relays Expansion 40-pin GPIO female header (2.54mm pitch) UEXT connector for sensors and modules Misc – 2x user buttons Power Supply 5V power jack LiPo charger and step up converter allowing ESP32-EVB to run from LiPo battery The company still have to write software samples, and do some testing to make sure the board work before going into mass production. Once everything is cleared, the board will be sold […]
