SmartPhone Controlled RGB MOOD Light

Mood lamps are always fascinating for me and is a very good project for starters to start with Arduino. What is a Mood Lamp ? Mood lamps are lighting devices that are used to establish a particular feeling or mood within a room. In some cases, this type of lamp may be a small device that is plugged into an outlet and creates points of light near the floor line of the room. Other examples of a mood lamp may ...

Arduino Radio

https://youtu.be/3WbK-S2WDLQ Update 16.04.2015 just thought how would a "cool" kit look a like, so I get an altoids tin box eat all the thinks inside and put all necassary parts inside. ;) a new project from good old Germany. I got some of those very popular FM radio modules at banggood.com, and was thinking how to use them. I found some nice instructables about the TEA 5767 most of them use a NOKIA LCD Dis ...

Motorized Pulldown Curtain (Phone & Radio Controlled)

https://youtu.be/v0-TlGm9BxM I pull my curtain up and down a couple of times a day. If I watch a movie I pull it down and then, I pull it up to get better lighting. I also pull it down when I go to sleep and I pull it up again when I wake up. I want this process to be automatic, if my curtain rises before I wake up, it will be easier for me to wake up when the clock goes off. Just like those night lights th ...

World’s first fully digital radio transmitter built purely from microprocessor technology

For the first time in history, a prototype radio has been created that is claimed to be completely digital, generating high-frequency radio waves purely through the use of integrated circuits and a set of patented algorithms without using conventional analog radio circuits in any way whatsoever. This breakthrough technology promises to vastly improve the wireless communications capabilities of everything fr ...

STEAMPUNK RADIO LOOKS THE BUSINESS

Radios are, by and large, not powered by steam. One could make the argument that much of our municipal electricity supply does come via steam turbines, but that might be drawing a long bow. Regardless, steampunk remains a popular and attractive aesthetic, and it’s the one that [Christine] selected for her radio build. The build cribs from [Christine’s] earlier work on a VFD alarm clock, using similar tubes ...

FAIL OF THE WEEK: THE ARDUINO WALKIE THAT WON’T TALKIE

There’s something seriously wrong with the Arduino walkie-talkie that [GreatScott!] built. The idea is simple: build a wireless intercom so a group of motor scooter riders can talk in real-time. Yes, such products exist commercially, but that’s no fun at all. With a little ingenuity and a well-stocked parts bin, such a device should be easy to build on the cheap, right? Apparently not. [GreatScott!] went wi ...

Teenager converts Porsche Boxster to electric drivetrain

While luxury carmaker Porsche works towards bringing an all-electric Boxster to production 11 years after it first started thinking about it, a sixteen-year-old from California’s Napa County has side-stepped the long wait (and the high price tag) and converted his own. Joining the likes of Simone Giertz (who, tired of waiting for a Tesla ute, made her own), St Helena teen Isaac Kelly decided that he wo ...

ELECTRIC WHEELCHAIR MAKES A GREAT BASE FOR A BIG ROBOT

Building robots can be fun, and remains a popular pastime among many in the hacker and maker set. However the hardware side of things can be daunting. This is particularly the case for those attempting to build something on a larger scale. A great shortcut is to start with a robust mechanical platform from the outset – and using an electric wheelchair is a great way to do so. [Nikita] started this project w ...

Sine wave oscillator using LM741

The oscillators are the devices that generate oscillatory (AC) output from given DC input. There are different kinds of oscillators based on the output waveform they generate. Like ·         Sinusoidal oscillators – they generate sinusoidal (sine) wave output ·         Square wave oscillators – they generate square (or rectangular) wave output ·         Triangular wave oscillators – they generate triangle o ...

Early Diagnosis Now Possible With Smart Bandage

IoE era is here since we are able now to add mobile radio capabilities in our applications! The latest incarnation of the cell phone network will offer internet connectivity and possibilities that could only be dreamt of previously depending on your standpoint, and many more factors. And now let’s embed these concept in medical applications, like “Smart Bandage” . It is conceivable that sensors embedded in ...

WISP – Re-programmable Microcontroller That Runs On Energy Harvested From Radio Waves

A new research initiative between the University of Washington’s Sensor Lab and the Technical University of Delft in the Netherlands has created a microprocessor that can power itself through stray radio waves and receive programmable updates in the same fashion. While the RISC-derived 16-bit microcontroller CPU is very weak compared to modern standards, it’s much more powerful than any other device that’s ...
