RGB LED Strip Light Alarm Clock

My son, home for the holidays, wanted to build an alarm clock that would wake him gently in the morning with lots of light. He lives in a basement flat out West and does not receive much natural lighting early in the morning. He plans to install 5-10 metres of inexpensive RGB LED light strip (see previous discussion) around the periphery of his raised bed. When the alarm activates, a cycle of slowly pulsing light emanates from below the bed. He is holidaying at the right place!

A software and hardware design made for hacking!

Here’s a video of the (nearly) finished clock:

White Oak Cedar-lined Blanket Box

Now, while not strictly a WoodUino project (for where are the flashing lights, I hear you ask?) it is nevertheless a project that has recently taken up a considerable amount of my time. I was commissioned to create a custom cedar-lined blanket box for a relative. Apart from rough dimensions (48″ W x 20″ D x 26″ H) and an instruction to “make it out of nice wood”, I was given a free hand so the rest was left to me.

ESP8266 WiFi Module: Data Logger

Now that I can fully exercise the AT command set of the ESP8266 Serial WIFI Wireless Transceiver Module, it is time to do something interesting with it – the WiFi Data Logger. To the ESP8266 module I added a temperature and humidity sensor and wrote code for the Arduino Nano to sample the sensor and transmit temperature and humidity to a data logging channel set up on www.thingspeak.com. This simple set-up makes it very easy to collect and display remotely-collected data using your local WiFi network to get to the net.

Here is a window onto the data being collected remotely by the WiFi Data Logger.

Dice Clock

Introducing the DICE CLOCK, shown here displaying the time in several different modes.

Dice Clock with boxes around time sections

Dice Clock with boxes around each time section (13:25 and 57 seconds)

Dice Clock with boxes around each mumeral

Dice Clock with boxes around each numeral (13:27 and 3 seconds)

Dice Clock showing hours, minutes and seconds

Dice Clock showing hours, minutes and seconds (13:54:18)

Dice Clock showing "domino" mode where hours, minutes and seconds are shown together

Dice Clock showing “domino” mode where hours, minutes and seconds are shown together (16:44:40)

The time is displayed as pips on a dice; a pair of which are used for hours, minutes and optionally, seconds.

Simple, elegant, cheap and, above all, HACKABLE!
