Introduction Time for another instalment in my highly-irregular series of irregular clock projects.  In this we have “Clock Four” – a scrolling text clock. After examining some Freetronics Dot Matrix Displays in the stock, it occurred to me that it would be neat to display the time as it was spoken (or close to it) […]

Back in January 2014 I was at a meetup of Baby Boomer Makers at TechShop in San Carlos, California. We were going around the table, each taking a turn to talk about projects we’d like to do. Bob spoke up to describe a problem his elderly mother was having – she couldn’t remember to take […]

Usually inventions are invented to serve a need or to solve a problem. So this small gadget that i constructed came to serve a need of mine.I have a NAS, Atom based file server, that runs on Ubuntu, but from time to time the operating system freezes and i have to cold restart it. The […]

This instructable teaches how to make our Bear With Me system, a prototype that allows two users to tangibly send and receive hugs (as well as motion) in near real-time. The bears will be able to send tweets when physically hugged.  Their hearts will glow when they receive the other bear’s hug.  The bears can […]

There is a lot of buzz going around Arduino and the series of boards. One of the most used board from the Arduino series is the Arduino Uno. But what many people don’t notice is that there is a board similar to Arduino UNO but has many more features. That board is called Freescale K64F. In this […]

In this project, we will learn how to use a speaker (peizo sounder) and use switch button to change the pitch of the sound. Sorry about this one, you might find it a bit difficult to digest at first, and I didn’t realise it’s actually harder than it sounds. Anyway, spend some time on the code, […]

Public Window (http://www.publicwindow.net) is an open source project which allows artists to display their creations in a window and have people from all around the world interact with it. This is a step-by-step guide on how to set up a Public Window of your own. A Public Window consists of an artwork connected via an Arduino […]

If you have two cats and one of them is on a diet but the other needs free food, you can build a feeder with RFID capability that only opens for the cat that needs free access. The free-food cat wears a collar with an RFID tag. Features: – An old CD-rom player is used as […]

In this Instructables, you will see how to Interface Moisture sensor to your NodeMCU. And check the moisture value and the same to be displayed on the LCD. We’ll use Liquid Clear Crystal to display the moisture value. This 16×2 LCD is very popular and broadly used in electronics projects as they are good for displaying information like sensor data from your […]
