Automated Backyard Studio Model Driven by an ESP32

by

The architectural model was designed using steel-reinforced concrete, glass windows, wooden steps, and an ESP32 for automation.

Architectural models are designed to approximate life-sized buildings in nearly every way, which is done for several reasons, including visualizing how light illuminates spaces, analyzing the best forms, and the relationships between spaces and materials. The Best Ever Architect’s Tiny Backyard Studio is one of those models and provides an understanding of home automation systems. While it may look simplistic, the model was created almost the same as life-sized buildings, beginning with a solid steel-reinforced concrete foundation, complete with pillars.

Hacking an old Nintendo Zapper into a wireless remote

by

Those of us who have experienced the Nintendo Zapper while playing games such as Duck Hunt will probably have fond memories of it. However, with the rapid disappearance of CRT TVs and the aging of the physical mechanisms, YouTuber DuctTape Mechanic wanted to give an old Zapper a new lease on life. His modification integrated a small RF transmitting module into the top of the device, allowing it to be switched on by the trigger’s microswitch. With everything in place inside the Zapper, he moved onto the receiver.

Controlling a ESP8266 with Alexa

by

Here is an easy project using a Echo Dot (Alexa) to control my ESP8266. I give it simple commands (Alexa, lights, off) and the command shows on the LCD screen attached to the ESP8266. Actual relays will be the next step to attach.

The project is based on the Adafruit tutorial at https://learn.adafruit.com/easy-alexa-or-echo-control-of-your-esp8266-huzzah/overview

with LCD and other modifications made by me. My code is found at https://pastebin.com/NjMcsTRh

SS4H-SD Smart Doorbell – DIY project based on ESP32

by

You surely know this feeling when the doorbell rings while you are doing something interesting: watching a movie, playing a video game, or spending a romantic evening with your loved one. And when it turns out that this is an uninvited/unwanted guest, you get even more pissed off.

Of course, you can ignore it and not open the door, but there will always be this hint of uncertainty – “maybe it was important”.

The solution to this problem is the “smart doorbell”. Thanks to it, you’ll know if it is worth getting up from the couch and opening the door or not.

Simple External and Internal Weather Station using Arduino Nano, DHT22, 433Mhz

by

Today I would like to propose a simple project that requires easy skills. It’s a simple weather station, that measures, internal and external temperature. It’s made out of two components: an indoor receiver, and an outdoor transmitter. The transmission is managed at 433Mhz. The components and the electrical diagram for both devices, are showed in the video. The receiver is very easy to use. to toggle between the external and internal temperature, you need to press the button for more than 3 seconds.

Digital LED Staircase lightening in motion using Arduino and Ultrasonic Sensor

by

Automated lightening of staircase not only helps to save electricity but also takes us to advancement in quality living of life. We generally uses normal circuit to turn on and off the light in stairs, but there is loss in electricity since we turn it off only at once during sleep. So, in this tutorial we are going to make the automated staircase that will light up only when it senses motion of people passing through stair.
