Have you ever thought about a speaker which can be controlled by your voice!!! Yes, Amazon Echo is the one of the most popular voice controlled Speaker, but in competition with it Google Home is also getting popular. Voice assistants becoming more popular as we are heading towards an era of AI based systems. You have heard about Google Assistant, Apple Siri and Amazon Alexa. These all are Voice based AI systems, what makes these different from each other is their ecosystems, and this is where Google Assistant standout the most. Google, Apple and Amazon, all these companies already launched their smart speakers. Google smart speakers are also available in the market. We already covered Raspberry Pi based Amazon Echo, this time we will turn Raspberry Pi into a Google Home Speaker.
I recently purchased the NeoPixel LED strip and was quite impressed by the way it works. The tiny LED’s have an inbuilt driver IC which helps us to control each LED individually and can produce a wide spectrum of colors. Being a garish person who is obsessed with colours I really loved watching these tiny LED’s changing colors so I decided to build something on my own and leave it coloring my bedroom during night times.
“Good morning. It’s 7:00 a.m. The weather in Malibu is 72 degrees with scattered clouds. The surf conditions are fair with waist-to-shoulder high lines. High tide will be at 10:52 a.m”. Every time I hear this voice of Jarvis in the movie Iron Man it sends me chills down my spine. I am sure just like me many would have dreamt of living a life as sophisticated as Tony Stark. But sadly we have not advanced with technology for a miniature Arc reactor or an AI as smart as JARVIS. But it is possible to replace our boring morning alarm clocks with the one that is similar to Jarvis using a Raspberry Pi. At the end of this project, we will create a very basic GUI using which we can set an alarm and when the alarm goes on we will have a voice which tells us the current time and day with some pre-defined text. Sounds cool right!! So let us build one: https://circuitdigest.com/microcontroller-projects/raspberry-pi-based-jarvis-themed-speaking-alarm-clock
Interfacing 3.5 inch Touch Screen TFT LCD with Raspberry Pi
The pi itself has a HDMI output which can be directly connected to a Monitor, but in projects where space is a constrain we need smaller displays. So in this tutorial we will learn how we can interface the popular 3.5 inch Touch Screen TFT LCD screen from waveshare with Raspberry pi. At the end of this tutorial you will have a fully functional LCD display with touch screen on top of your Pi ready to be used for your future projects.

Hi guys, during the last few weeks, I’ve been working on reconnecting with my love for the guitar. Playing the box guitar was how I relax few years back before the saxophone took over. Going back to the guitar, after 3 years of rarely strumming a chord, I discovered amongst other things that I no longer knew how each of the string should sound, to put it in my friend’s words, “My hearing was no longer tuned” and as a result of this, I was not able to tune the guitar without the aid of a keyboard or a mobile app which I later downloaded. The weeks went by till few days ago when the maker in me became motivated and I decided to build an Arduino based Guitar Tuner. In today’s tutorial, I will be sharing how to build your own DIY Arduino Guitar Tuner.

Minecraft is one of the most popular game in the world and people are getting additive for this interesting game. You can setup your own Minecraft server and can create your own worlds in the game. For this, you don’t need to spend money on a dedicated PC, it can be easily done with a small, credit card-sized Linux computer Raspberry Pi. If you want to play it on small LAN network with your family and friends then Raspberry is the perfect choice for you. Graphics of this game is not good but still it looks so fascinating to play this game on network with other people.

Controlling Arduino with Raspberry Pi using pyFirmata
We use PyFirmata firmware to give commands to Arduino using Raspberry Pi python script. PyFirmata is basically a prebuilt library package of python program which can be installed in Arduino to allow serial communication between a python script on any computer and an Arduino. This python package can give access to read and write any pin on the Arduino. So here we will run python program on Arduino using Raspberry pi.
So in this tutorial we will take advantage of this library and will use this in our Arduino board to control Arduino using Raspberry Pi.
Today I will be demonstrating how to use the Arduino and a software, which will be developed with my favourite programming language Python, to build a low cost, 4-channel Arduino oscilloscope capable of performing the tasks for which some of the cheap oscilloscope are deployed like the display of waveforms and determination of voltage levels for signals.

DIY Wi-Fi Jammer using NodeMCU ESP12
There is a Wi-Fi protocol called 802.11 which act as a deauthentication frame. This is used to safely disconnect all the users connected with the router. To disconnect any device from some Wi-Fi network, it is not important to know the password or to be in the network, you just need mac address of the Wi-Fi router and client device and it is enough to be in its range of that Wi-Fi network.
