Hello, the prototype of the bracelet!!
Written by viola on September 19th, 2008| “Little by little!!” My flamenco teacher always says this to me. This is principle can be used in almost everything.
1) This is first step. How to use an audio amplifier to send a signal??? I used LM386, a low voltage power amplifier. Thanks Liubo! |
 |
| 2) After making sure everthing was ok, I soldered the circuit on a board.:) I learned during my internship. Thanks Ayah! |
 |
| 3) I did a little more programming testing with Arduino. Making sure that the lighting effect will be as I expected! |
 |
| 4) Then I used the same trick that I worte about it before. Tada!! Yes, the wire wrap tool and wrap to connect the LEDs with the cute Lily Pad. (Lily Pad! What a good invetion!!) |
 |
| 5) Almost there, but how can I power it? I used the DL2032 3v button battery in the beginning. However, sadly the current is not strong enough. After testing with several kinds of batteries, PANASONIC CR2450 is the winner!! |

6) haha… It is sitll not the end but today I will teach everyone a saying, which comes from Zhou Dunyi, a philosopher of the Song Dynasty of China. In his famous articl, LOVE LOTUS SAYING, he said “ .” It describes why the lotus is so beautiful. The reason is that although the lotus was grown in silt, it is not impure but elegant. This is like the story of my desk and my flower-like bracelet. |
