I’m not going to explain in detail what is ESP8266 because if you have found this post I’m sure you already know it. But just in case, it is an awesome cheap board (less than 4$) with built-in wifi communication (802.11 b/g/n), and SPI, UART. You can also use its processor to run your code. Wiring: Use […]

Minimal power consumption, slim design and a big amount of available versions with multi-color backlight – these are some benefits of the EADOG series displays. EADOG series is familiar to many of you and probably it´s your favorite one from these main reasons: displays are unusually flat (thin) the have a very low power consumption
Industrial applications rely on the EA DOG displays Continue Reading
In this tutorial Dave describes what AC trigger coupling is on an oscilloscope and why it can be useful. Not only on old analog CRT oscilloscopes, but modern digital scopes as well. How and why is it different to AC channel input coupling? Also, use of the 50% trigger control, and how the venerable DS1052E

Today’s “Back to Basics” tutorial topic – why flyback or snubber diodes are used around relay coils when switched or controlled by low power electronics. We’ll talk about how and why dangerously high voltages can be generated from the collapse of the stored magnetic energy in the coil when they’re switched off, and how the
