Natural light alarm clock

Posted on October 21, 2016 by R-B Leave a comment

We are programmed to wake up gently with the natural light of Sunrise. Unfortunately, this rarely happens in modern days, where we are often forced to wake up with a loud noise of an alarm clock. However, things have started to change recently with the introduction of natural light alarm clocks, or sunrise alarm clock. A natural light alarm clock implements an artificial sunrise by emitting light that progressively increases in intensity and tells our body that the sun is rising up. Most of the commercially available natural light simulators are kind of expensive. But if you are a DIY person, there are simple ways to make

PC stats on a tiny OLED

Posted on October 18, 2016 by R-B Leave a comment

Rupert Hirst bought a new Nvidia GTX1080 graphics card, and in order to monitor its performance, he built an external PC stat display using an Arduino Pro Micro and a 128×64 pixel I2C OLED display. Note that unlike in Arduino Uno, the I2C pins on the Pro Micro are available at the D2(SDA) and D3(SCL) I/O pins. In order to minimize the footprint of his project, he directly hooked the 4 pins (VCC, GND, SCL, and SDA) of the OLED display to the 4 I/O pins in a single row (D5, D4, D3, and D2) of the Pro Micro to minimize

A multifunctional Arduino clock

This multifunctional Arduino clock does more than just showing time. Besides displaying time, date, and day of the week, it also measures the ambient temperature and humidity, runs disco LED lights with music, and has a built-in speaker to hook an audio source like a mp3 player.

Rotary dial phone gets GSM upgrade

Posted on October 15, 2016 by R-B Leave a comment

I found this nice Instructable from Acmecorporation on upgrading an old-school rotary dial telephone to a GSM phone using Arduino and a SIM900 GSM shield, while preserving the classical ringing sound, sluggish rotating dialer, and a heavy handset. These kind of telephone cannot be used now days due to incompatibility between pulse and tone dialing. Before trash it i ask to myself: how can i transform it? My aim was to replay old feelings: classical ringing sound, rotating dialer and a heavy comfortable handset. Then i decided to relive that and so, in this instructables, i’ll show how to transform a rotary dialer telephone to GSM

Display traffic status on a wall clock

Posted on October 12, 2016 by R-B Leave a comment

Navigation apps are handy these days to get live traffic updates and minimize the wait time on road. This Arduino based traffic status display clock does the same thing but in a cool way, using colorful RGB LEDs. It’s built with an ordinary wall clock and 12 RGB LEDs installed around the clock. The color changes based on the traffic condition. The Arduino board receives live traffic information using 1sheeld and Google Distance Matrix API. 1sheeld is a bluetooth-enabled shield and acts as a bridge for Arduino to access the smart features of the smartphone as well as allows to use the smartphone as various
