1btn is a Battery Powered Open Source ESP8266 WiFi Button

If you have some WiFi power switch like Sonoff TH16 at home, you’d normally control them using a mobile app or a web interface. This is all good, but getting your phone, unlocking it, and launching the app to turn on or off an appliance is not the most efficient way to operate, and in some cases, some people in the household may not know how to use a smartphone. Physical WiFi buttons are the solution, but there aren’t so many for sale. We’ve seen previously it was possible to hack an Amazon Dash, but it’s not really that flexible, and 1btn could potentially be a better option, as it’s open source and based on Espressif ESP8266 WiSoC. 1btn specifications: WiFi Module – ESP-12F based on Espressif ESP8266 MCU – Microchip Atmel ATmegaxx8 AVR MCU Connectivity – 802.11 b/g/b WiFi up to ~50 meter range USB – 1x USB port […]

Sonoff B1 is an $18 Hackable WiFi RGB LED E27 Light Bulb based on ESP8285 WiSoC

Earlier this year, I wrote about an ESP8266 based RGB LED “AI Light” lightbulb that was hacked to run ESPurna open source firmware. That’s all good, except some people tried to get one, and ended with a different hardware. So if you’d like something that’s more of a “sure thing”, ITEAD Studio has designed Sonoff B1 dimmable RGB LED E27 light bulb based on ESP8285 processor, and with a “4 pads” to allow for custom firmware flashing. Sonoff B1 hardware specifications: Typical Lumen Output – 600lm Beam Angle – 120 degrees typ. Color Temperature – 2800K-6500K & RGB full color Connectivity – WiFi 802.11 b/g/n @ 2.4GHz Power Supply – 90-260V AC 50/60Hz via E27 base Power Consumption – Light off: 0.5W Max; rated power: 6W Temperature Range – Operating: 0ºC~ 40ºC; storage: -20ºC~ 80ºC Operating Humidity – 5%-90% RH Sonoff B1 with stock firmware can be controlled using the […]

A95X R2 TV Box Review – Part 2: Android 7.1, Video & Audio Tests, and Benchmarks

In the first part of A95X R2 Rockchip RK3328 TV box review, I listed the specifications of the device, took a few photos, and reported about the chip used in the PCBA. I’ve now had time to play with the box, so I can report about my experience with Android 7.1, video & audio capabilities, and the performance of the device in the second part of the review. First Boot, Setup, and First Impressions I connected a USB 3.0 hard drive to the USB 3.0 port of the box, a USB keyboard to one of the USB port to take screenshots, and a USB hub with the RF dongles for my air mouse and gamepad in the remaining USB 2.0 port. I completed the hardware setup with Ethernet and HDMI cables, as well as the power supply. I then pressed the power button on the unit to start it up, […]
