JYE Tech JYE Tech DSO Coral 112A Oscilloscope
DSO Coral (112A) is an upgraded model of DSO112 with re-designed schematic and PCB. Due to the new design this oscilloscope becomes more accurate and reliable. As high as 2 mV/div sensitivity and ultra low background noise made the device particularly useful for measuring weak signals. Up to 24 presets with customizable titles allow setups be retrieved in seconds. While keeping all performance of DSO112 this new model brings in the following improvements: Maximum sensitivity was increased to 2 mV/div (older version is 5 mV/div) with lower background noises. Fixed the vertical position mismatch problem found in the older model. Save/recall up to 24 parameter presets. This allows quick setup for frequently performed measurements. Preset titles can be customized for easy remembering and identifying. Expanded and improved on-screen measurement displays which include frequency, Vmax, Vmin, Vavr, Vpp, and Vrms. Added external trigger feature. Provided a two-way serial control interface which can output data/measurements and receive commands. This will make the device suitable for integration to customer applications. Replaced out-dated miniUSB connector with more popular microUSB connector. Enclosure strength enhanced.

Elektor Digital IoT Home Hacks with ESP8266 (E-book)
There are many so-called 'Arduino compatible' platforms on the market. The ESP8266 – in the form of the WeMos D1 Mini Pro – is one that really stands out. This device includes WiFi Internet access and the option of a flash file system using up to 16 MB of external flash memory. Furthermore, there are ample in/output pins (though only one analogue input), PWM, I²C, and one-wire. Needless to say, you are easily able to construct many small IoT devices! This book contains the following builds: A colourful smart home accessory refrigerator controller 230 V power monitor door lock monitor and some further spin-off devices. All builds are documented together with relevant background information for further study. For your convenience, there is a small PCB for most of the designs; you can also use a perf board. You don’t need to be an expert but the minimum recommended essentials include basic experience with a PC, software, and hardware, including the ability to surf the Internet and assemble PCBs. And of course: A handle was kept on development costs. All custom software for the IoT devices and PCB layouts are available for free download from at Elektor.com.
