TV-B Gone
The TV-B gone is a small handheld universal remote that can turn on and off any TV within a certain radius (100 feet). This device also allows the user to control when they see instead of what they see, this device works by shining pulses of invisible light which is recognized by the TV causing it to turn on or off. This device uses the principles of electronics to emit a digital signal that is received by the TV, is interpreted, and then depending on the state causes the device to turn on or off.

How it works
The way this device works is by using power from batteries it is fed to the ground and VCC which is also connected to the micro-controller (pin 4 and pin 8 are connected to VCC and Ground) which is already preprogrammed with software to make the TV it comes in contact with turn on or off. Pin 1 is connected to a switch which then in turn is connected to another ground. Pin 3 and pin 2 are connected via a jumper to the oscillator or the XTL1. Pin 7 for this micro-controller is the output pin connected to a 1k resistor and a green LED which will transfer the IR signal to the TV. Pin 6 is connected to a 10k resistor and then to ground. This leaving pin 5 which outputs a signal to the other 4 LED’s which are connected VIA transistors and the other ends are connected to resistors of different values. There are also 4 NPN transistors whci hare connected before the LED's and 1 PNP transistor that is connected to pin 5 on the microcontroller. All these different components work together to make the TV-B gone a device which can turn on or off monitors and screens using infrared rays. |
How this relates to my future career
This device is a great first step into the field of electrical engineering, this is due to the fact that IR technology can have numerous uses upon advancements of this technology. This technology is currently being used in space to control shuttles and other unmanned technology, it can also be used to create new type of technology such as for infrared data transfer and even for IR peripherals such as Celluon’s Epic (keyboard) or evoMouse that uses IR technology as sensors to perceive what the user is indicating and then converts it into a digital signal working as a peripheral device. Looking at these inventions it is truly fascinating how technology like IR can be still developed and integrated into new devices such as the holographic keyboard and mouse. Microsoft is even developing their own IR tech for data transfer to try to send files, pictures, and then receive them using IR tech would be revolutionary. It are devices like these are related to my future career of Electrical engineering. |
Environment and Social impacts
This type of technology is great due to it using harmless rays to transmit signals as compared to its alternatives which are much harsher when compared to IR, however when used improperly IR can still be dangerous. IR is also environmentally friendly as is does not produce any byproduct that can be harmful and is also it had a long wave length and lower energy meaning it can be used for longer distances as compared to some of the other types of waves used for signaling.
