Saki Tech!

A short video about an advanced domotic project I’m working on.
It’s involve Android, Arduino and many sensors.

“How to do” Spoka Box, step by step.

Spoka circuit exposed, test on switch on/off current and status (on/off) sensing;
the “E” made from an IKEA spice rack;
the main box core. Seeeduino Mega + RTC + Graphic LCD + buttons and trimmer circuit + Spoka control circuit;
Spoka mod: a second hole to connect with main box;
Spoka on;
main box semi-assembled;
main box a step before ending;
main box jacks image, one for speakers and one for Spoka;
Spoka Box assembled! “E” painted, main box wrapped in cloth and 2 magnets embedded into the upper part of the “E” to keep the main box securely in place.

First post on Spoka Box

Finally!! The SMS received a great upgrade!!

Its name is now Spoka Box, from the funny animal (brought at IKEA) you can see into the photo.

“How to” into next posts.

The main functions are:

current time;
day, month, year;
alarm;
random sentence under clock;
Spoka switchs on 10 minutes before alarm time;
Spoka blinks during alarm;
Waka waka (by Shakira) plays during alarm;
Spoka switchs off 15 minutes after alarm time;
random sentence by menu option;
alarm simulation by menu option;
simple cartoon by menu option;
set time, date and alarm menus;
set lcd light by turning a trimmer;
Spoka is totally autonomous from main box actions, you can switch it on manually (with a button on its head) and the alarm function will gets its status (on or off) from a little board into it.

Finally!!

A new project done. ;)
Exams passed and free time increases a bit.

This is a capacitive button done with an Arduino, the CapSense Library, a 1M Ohm resistor and a thin aluminum foil.

The principle is very easy: this is a capacitive sensor that measures the electric charge of human body or other metal items.
It needs an 1M Ohm resistor to work as a button, from 10 to 20M Ohm resistor to sense at 6-7 cm, or 50M Ohm resistor to activate the input from 20-30 cm of distance.

In the video you can see a direct application.
A ledbar shows the distance read and a relay (you can hear its “clack” on the background) is activated when the sensor is completely touched.

You can see a complete “how to” and the Arduino code here:

Sorry, italian only! But you can translate it with google.

Electric scheme of S.M.S. project!

This is the video of my S.M.S. project in action.

I hope you enjoy it.

This is my Christmas project for my little darling!

S.M.S. (Scatola Magica della Solitudine) [in english: Magic Box of Loneliness].

The goal was to give her a present to remember me and don’t feel loneliness.
The box have two buttons.
Button A shows some random sentences to encourage her.
Button B shows a simple romantic “cartoon”.
;)

The core is an Arduino Duemilanove board.
The lcd used is this one, with some code from here, and the code used for cartoon and “sentence random function” are totally mine.

P.s.: a video of its functions in the next post.
