ReSpeaker Messenger: Sending and receiving Slack and Telegram messages using ReSpeaker Voice Interaction Board My previous project using ReSpeaker was a Home Automation project to control different lights using your voice. This projects is about sending messages to Slack or Telegram using voice input and read out the message from the messenger. User can…
In this project, I am going to show how I made Alexa enabled home monitoring and controlling system using RSL10 Sense Development Board from ON Semiconductor. RSL10 is used to sense the environmental parameters (temperature, humidity, air pressure, and light intensity) of a room. An Alexa Skill was developed to remotely access these…
https://youtu.be/tNOX1KDlOIM Time is like a torrent, pushing people forward. Is there an instant in which you want time to stand still or go backwards? Look closely at the water droplet. Is it dripping down or going up? The work is inspired by the phenomenon of visual persistence. The sound movie has 24 frames per…
•The percentage of disabled people has increased in both rural and urban part of India. The disability could be by birth or due to some medical or accidental reason. •The aim of this project is to make a hand gesture controlled wheel chair and using Accelerometer as sensor to help the physically disabled people…
One of the essential elements of building IoT project is the ability to connect devices. Wi-Fi and Bluetooth are good low cost choices, but they work only at close ranges, or in hotspot areas. When the device needs to be at a remote location GSM is a good and easy to setup option. In this Tutorial, I will…
Build a cloud weather station dashboard to visualize your ESP32 or ESP8266 sensor readings from anywhere in the world. You’ll see your sensor data displayed on gauges and on a table. The ESP32 or ESP8266 will make an HTTP POST request to a PHP script to insert your data into a MySQL database. More info
An Arduino-based GPS clock using a microcontroller with a gps attachment and a 12-neopixel ring. I based this project on Adafruit’s awesome Neopixel watch. This project uses an Arduino-friendly microcontroller (the smaller, the better – I used an Adafruit Flora), with an added GPS chip to determine the time, and a 12-neopixel ring. A pink/salmon…
Command centers need to know where their people are and where danger exists and may be approaching them. This system tracks fire boundaries & fire hotspots and firefighters or other persons on-the-ground and relays this data back to command centers where it is mapped in real time. The drone roams via a planned route…
Resin 3D printers are finally cheap enough that peons like us can finally buy them without skipping too many meals, and what means we’re starting to see more and more of them in the hands of hackers. But to get good results you’ll also want a machine to cure the prints with UV light;…
While best known for Charlie and the Chocolate Factory, Roald Dahl wrote quite a few similarly oddball stories in his time. One of them, The Sound Machine, is about a device that allowed the user to hear the anguished screams of trees as they were cut down. Sounds kind of weird to us, but [Roni Bandini] liked the…
We see a lot of 3D printers here at Hackaday, but as over the years the 3D printer has moved from being an exciting item in its own right to being an everyday tool, it’s increasingly rare for us to feature a build of one as a project. It’s especially rare for us to…
[Lewis] of [DIY Machines] was always on the lookout for that perfect something to hang above the couch. After spending a lot of time fruitlessly searching, he designed and built this awesome shelving unit with recessed lighting that doubles as a huge 7-segment clock. The clock part works as you probably expect — an Elegoo…
