USB Bell: Dingdong:
If you’re fond of receiving emails or make use of chatting via Facebook, I think you already know what particular sound indicates an email or a Facebook message.
However, how would you react if you will actually hear the sound of a ringing bell when you receive your email? Well, you must check this USB powered and controlled bell or in short the USB bell.
Apparently, the USB bell is a project that aims to be useful in receiving email notifications.
It mainly consists a mounted micro-controller inside the base of a counter bell that will produce the sound by the pulling of electromagnet on the bell’s clapper, then it communicate with the computer over USB.
This may sound geeky to you, but the project creator of this device is so kind and helpful in sharing his innovation.
While some may think that this project is absurd and the designer is one of those attention seekers, none of us can tell what he truly has in mind. But interestingly, he explained the step by step instructions in making the USB bell, of which he claims that it is so easy at the instructables.com.
He posted the following requirements in order to put up a USB bell:
1. Soldering: solder six electrical components together.
2. Knowledge of electronics
3. Knowledge of programming (optional)
1. A counter bell with a steel clapper
2. A short bolt
3. A transistor
4. A resitor
5. A large capacitor
6. A diode
7. A forebrain dev board
8. Some prototyping board and wires.
Obviously, this project is of very great interest to those geeks, but there is a warning in proceeding with the USB bell. This is risky both for you and your computer. It may cause injury to you if mistakes were done and damage to your PC too.
