I have almost finished! On this part I will explain how I built everything up. First of all, a list of all the material that I needed to setup my installation:
1. The Processing console;
2. An Arduino board;
3. A breadboard;
4. 3 BDX53F transistors;
5. A 12V/1.5A adapter;
6. 3 computer fans;
7. 8 threaded bars;
8. A couple of blue […]
The final Processing code. To process the sound I used the ESS library that reads the spectrum of a sound source. The website of this library can be found here: Link.
The following code is taken by the library website, and changed by me to make it work with my installation
Here I import the Ess library […]
On this post I will write the final Arduino code. It is set up to receive byte from Processing divided into three range of numbers. Probably is not the cleanest of the solutions, but unfortunately I did not manage to send strings of byte or to set up a protocol to read the three bands […]
For my project, the Arduino output is not enough so digging on the net and asking to a friend some help, I managed to build an amplifier to feed my 3 computer fans.
This circuit can be used as an amplifier to switch on and off a DC motor and to regulate its spinning speed with […]
The second problem is that the piezoelectric pad produce such a short signal that is quite impossible to read it and transform the signal into something visible. So I decided to use a microphone as the input device to read longer signal and to have a more representative way of the inner features of sound. […]
As said on the previuos post, the flying toys won’t fly or at least they will not fly using the output that the Arduino board would feed them So I switched over to using fans instead. So I went to the electronics stuff show and asked about the biggest computer fan that they would have. […]
Unfortunately I didn’t manage to find any solution about the radio controller of the flying toy working only as a switch, so I have to, and forgive me for my play on words, switch idea.
Instead of having the toys fly when they receive the message from the radio controller, I will stop them, control them […]
Playing with the flying toy, I found out that there is no potentiometer to control the power of the output. The only signal that the receiver mounted on the disc receives is a on/off message. I have tried to twik the output voltage, but it only becomes a lower emitted message from the antenna.
So I […]
