Factory Prices of Some TV Boxes and Accessories

September 12th, 2017 13 comments

Some companies that contact me have not read the about section of the blog, and either tell me they can give me a good price for TV boxes, and some even send me their price list. And this morning, I’ve received a EXW (Ex Works) price list this of Amlogic S912/S905X/S905W and Rockchip based TV boxes, as well as some air mice, and Android projectors. The cheapest models are based on S905W and RK3229, with MXQ Pro 1GB/8GB going for $17.5 per unit for 200 pieces orders. For reference that models goes for around $26 shipped online before any discount coupon you may find. At the other end of the scale, you have TX2 model with 3GB RAM, 64GB flash going for $77.5 EXW for 200-unit orders, and sold online for $86 including shipping, again before coupon. Margin must be really low, or the prices above are not that competitive, but nevertheless it gives an idea of factory prices of…

Review of Sonoff RF Bridge, Sonoff 4ch Pro, and Sonoff POW with Sonoff-Tasmota Firmware

September 12th, 2017 No comments

Karl here. Today we are going to look at 2 new and one older Sonoff devices. Sonoff RF Bridge – $9.90 433MHz RF to WiFi Bridge Sonoff 4ch Pro – 4 Gang WiFi RF Smart Switch Sonoff POW – Wireless switch with power metering capabilities I spent very little time with the stock firmware on the device. I don’t like the fact that an Internet connection is needed, and I am not in control. As of the time of this writing I found the Ewelink was not configurable enough to meet my needs. There is one feature that is really nice that I could easily see keeping stock firmware. It is the Alexa Skill. It worked. I am also currently reviewing Vobot Smart Alarm Clock with Alexa integration and had no trouble controlling the Sonoff devices with Alexa. But unfortunately I am lazy and want everything automatic so I can’t keep it. With the RF bridge I was unable to…

How to Remove Watermarks & Timestamps from Photos with GIMP

September 12th, 2017 5 comments

Watermarks can be seen on some photographs for copyright reasons, but in some cases even people or companies who clearly don’t own copyrights add watermarks, such as online resellers who add watermarks on top of photos provided by manufacturers, and some camera adds date & time automatically to photos if you’ve used the  settings to enable it. I’ve recently read a blog post on Google Research about making watermarks more effective, as some computer algorithm could remove watermarks automatically. Since I often waste time while searching for watermark-free version of the photo, I decided to check if I could find such program running in Linux. I did not but I found a somewhat old blog post explaining how to use GIMP to perform the task with three different methods: Crop, if the watermark is on the edges… Easiest method, but for most case this won’t do… Content-aware filling using resynthetiser plugin. Automatic and easy, but results will depend on source…

September 11th, 2017 No comments

Venus Supply Co., Ltd, better known as ThaiEasyElec, is a company based in Thailand, selling embedded systems and development board, as well as providing development services based in Thailand. The company sent me their latest board called ESPino32 powered by Espressif ESP-WROOM-32 WiFi and Bluetooth module for evaluation. While the board is supported in Arduino-esp32, I’ve already tested Arduino with ESP32-Bit module & ESP32-T board, so after checking out the hardware, I’ll load it with something different: Espruino, a firmware allowing for JavaScript programming over the serial console, or a Web based IDE. ESPino32 Unboxing and Soldering The board shipped with four female headers, and I/O stickers. The board includes ESP-WROOM-32, exposes I/Os through four 10-pin headers, features CP2104 chip for serial to USB debugging via micro USB port, two buttons (reset and program), a user LED connected to IO16, and a jumper to select between regulated power supply (micro USB or Vin), or battery power (Vbat).
