Today we will make a room temperature monitor, which we can use to monitor our room from anywhere in the world and to do that we will use a BLYNK IoT plateform and we will use DHT11 to read the room temperature we will use a ESP8266 to access the internet and it will send that temperature data to the BLYNK server.
Let’s prepare the G-code, starting from the Gerber file, so to finally print our PCB. In the previous installment, we left you after having analyzed the hardware that enables us to manage our CNC by means of whichever modern computer that is not supplied with a parallel port (as long as it supplied with…
If you have a circular saw you probably use a tape measure every time you want to cut a piece of wood and make pencil marks after you find the desired length. In this project we will see how to simplify the process by creating a device that accurately measures cuts every time. You won’t…
