The world is an immense place, distances and global connectivity is often difficult to comprehend and global friendships tend to be forgotten due to daily, closer in proximity matters and demands...
The ANTGlobe serves as a sort of pedestal for your foreign friends and experiences abroad. By pinning your locations on the globe and storing information within the pins you can track your global network in a more visual and interactive sense, storing your far away memories within the reach of your hand.
An interactive globe to collect the places we have been.
To Interact with the memories we have made.
To never forget the people we have met.
The idea is, that when you make a new global connection, you can simply add a pin to the board, create a connection to your Arduino board and track your global connectivity. Once a pin on the globe is touched, visual and audio feedback is given, this can be a simple picture of your friend, voice message in a foreign accent or even a video.
A short introduction to Capacitance
If two objects are conductive you can measure the capacitance between them. In our circuit a weak signal is sent to one pin, while another pin is used to measure how the objects voltage changes. When we touch the coper pin, the signal gets higher and if the input number raises beyond our set threshold, touch is measured as positive.
Using this method, you can use many objects as capacitive sensors, anything from a pencil drawing to a potato could work, I highly encourage you to check all the incredible projects available online!
Components and Tools
The DIY capacitive sensing board
The DIY C.S board is made on a piece of R200-RP perfboard according to the wiring diagram on the right, make sure to bridge the pins correctly. The basic idea of the capacitive sensors is to connect a sending pin to a receiving pin with a resistor in between (1 Ohm in our case), which is then connected to the capacitive sensor.
You can download the entire code from GitHub, I also wrote about the writing of the code and some debugging on my developers blog. Make sure to save your images and sound bits in your project data folder, and to upload the minim library for playing sound.
I recommend Daniel Shiffman's 'Learning Processing' if you are new to the processing language and need a guide.
