Kerala's First 3D Printed Building

Created as a showcase project, AMAZE-28, the single-room summer house, was successfully constructed within 28 days on the grounds of the Kerala State Nirmithi Kendra. The 3D-printed building at the Kerala State Nirmithi Kendra in Thiruvananthapuram. (Photo: Shekunj)  The inauguration of Kerala's inaugural 3D-printed structure, a 380-square-foot single-room summer house, is scheduled to take place on October 10 at the Kerala State Nirmithi Kendra (Kesnik) campus located in PTP Nagar, Thiruvananthapuram.  Conceived as a showcase initiative, the summer house named AMAZE-28 was successfully finished within a mere 28 days. This impressive project was executed by Tvasta, a construction technology startup based in Chennai, founded by alumni of IIT-Madras, who have entered into a memorandum of understanding (MoU) with Kesnik.  AMAZE-28 is perched upon a concrete foundation atop a gentle elevation within the Kesnik campus.

Micro-Python on NodeMCU ESP8266 (Windows guide)



This tutorial will guide you through setting up MicroPython on NodeMCU, getting a prompt, using WebREPL, connecting to the network and communicating with the Internet, using the hardware peripherals, and controlling some external components.

Requirements –

1.       NodeMCU Module
2.       Laptop with Python installed. (Here I am using python 2.7).
3.       Internet connection

Connecting the board to Power-

Connect the board to your laptop through USB to power it up. You can also give it external power supply at Vin pin (shown in fig. below). Please refer to the documentation for your board for further details.
Figure 1: NodeMCU Module

Firmware download –

Download the most recent MicroPython firmware .bin file to load onto your NodeMCU device. You can download it from here, and place it in your python/Scripts directory from earlier (screenshot).

Flashing the Firmware –

Before flashing the firmware I assume that you have python (2.7) with pip tool.
So, follow the following steps –
·         cd /
·         cd Python27 (or whatever directory you installed it to)
·         cd Scripts
·         pip install esptool
esptool – it is a Python-based, open source, platform independent, utility to communicate with the ROM bootloader in Espressif ESP8266.


  • Plug your USB cable into the NodeMCU board, and then into your computer.
  • Go into device manager and confirm what port your device is on. We'll need this information later. I'm on COM port 3 (screenshot).
  • Place the NodeMCU board into bootloader mode by holding the flash button, pressing the RST button, then releasing the flash button. You'll see the blue light briefly flash once when you've done this (screenshot).
  • Open a command prompt, and return to the scripts directory.
  • Run the following command, keeping in mind to substitute COM3 with YOUR particular COM port:
esptool.py --port COM3 --baud 460800 write_flash --flash_size=detect 0 esp8266-20161110-v1.10.bin
Congratulations!!!! You've successfully flashed Micropython onto a microcontroller!

Connect Using TeraTerm + WebREPL - (coming soon...)

Controlling LEDs over WiFi using NodeMCU and Blynk App.

This article is the base on the Internet of things ( IoT ) . IoT describes the network of physical objects—“things” or objects—that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the Internet. In this article 3 LEDs will be controlled by an android application (made using Blynk) over a wifi connection. How to use NodeMCU with Blynk  If you want to start learn the Internet of Things (IoT) concept, then controlling a LED over the  internet is the " Hello World!" of the IoT journey. Performing the " Hello World" task will be easy using NodeMCU micro-controller as the first client and Blynk as the 'broker' or server and Blynk android application as the second client. Now communication between two clients will happen through broker over the internet. Now lets, make this happen.  Components Required For this activity we will need following components: Nod...

How to Know the NodeMCU IP Address for Your Next IoT Project

  NodeMCU IP Address: The NodeMCU is a popular development board for IoT projects. It’s small, affordable, and comes with built-in Wi-Fi connectivity, making it the perfect choice for creating connected devices. But before you can start building your NodeMCU projects, you need to know the IP address of your device. This IP address is essential for communicating with the NodeMCU from another device, such as a computer or smartphone. In this article, we’ll show you how to find the NodeMCU IP address, so you can get started with your next IoT project. Method 1: To Know the NodeMCU IP Address One of the easiest ways to find the NodeMCU IP address is by using the serial monitor in the Arduino IDE. First, connect your NodeMCU board to your computer using a micro-USB cable. Then, upload the following code to the NodeMCU: #include <ESP8266WiFi.h> void setup() { Serial.begin(115200); Serial.println(); Serial.print("Connecting to "); Serial.println(...

Blinking of LED Using Arduino UNO

Hi !!!! Here we are going to learn very very simple use of Arduino, that is blinking of a LED. Here we will do simplest project using Arduino. So, here we go.... COMPONENTS REQUIRED - Bread Board Arduino UNO Jumper Wires Power Source (5V) / Battery Resistor (1K) CIRCUIT PREPA RATION - Take bread board and Arduino. Connect the +5V from Arduino to the +Ve line on Bread Board and GROUND from Arduino to -Ve line on bread board. Red Wire     : +5 V Black Wire  : GROUND     Now put a LED on bread board. Connect the Anode (+ / Longer terminal) of led to the pin 13 of Arduino. Connect Cathode (- / Shorter terminal)  to 1K ohm resistor and connect another terminal of resistor to the GND on breadboard.   Now our circuit is ready to work.  Our next aim is to build the code. Let's make our code. CODE -     To download the complete code -  CLICK HERE -----------------------------...
