Recently I needed head regulation and it was super easy & cheap to implement using ESP8266 & Blynk. And yes, I know that both exist for a quite long time, but I didn't do "simple analogue in/out IoT" for a long time.
Just the beginning of mess I made |
DHT11 with Blynk app |
Blynk is IoT platform, it has Android and iOS client apps, libraries for most popular development boards (including ESP8266) and the most for important for me it is open source. Unfortunately, they still don't have a web client.
Today I successfully replaced Xiaomi Note 4X screen!
A touchscreen was completely was completely broken. However, screen used to work until I accidentally cut a screen cable during the disassembling process. Therefore, I had to buy both, screen and touchscreen which cost around 20e.
The screen is not the same quality as it used to be, but I am still happy as I disassembled and assembled a the l parts of phone.
