Television Sensor

These days Kavin has become very careless about switching off the TV. He watches it for some time and goes away either to his room or to play on the PC while the TV is still running. So me and his Appa keeps telling him to switch-off the TV and help in saving the electricity. One day he totally got fed up with our reminders and said-"I want a TV sensor. It should sense that there's nobody in the room and switch-off the TV." Kabi asked him how to make such a sensor.
He said-"We can use the car's reverse-sensors to develop our TV sensor."

Kabi is trying to develop such a sensor using a relay switch and a motion sensor with the help of Kavin, let's see where it goes!

Intruder Alarm!

Yesterday Kavin came up with a new idea. For many days, he's been working on a intruder alarm design for his room(his main intruder is our maid-Rathnamma). Initially he made a maze with a sewing-yarn in his room, so that no one should be able to enter his room.
Then he got an even better idea- he took a thick rope, tied it on his door and at the end he tied a Pooja bell so that whenever someone enters his room the bell would make a sound and he'd be alarmed. It was cute!

Wise horn!

Recently we went to a small hill station called Yercaud. The drive was quite good. The route to this place comes under golden quadrilateral. So the roads were very good to drive. On the way we encountered many crazy drivers who kept honking their heart out.It's quite irritating on a highway. Inside the city, we are used to it, but on a free highway, it feels like a menace.

So our man came up with an idea. He said he is going to make an intelligent horn. This horn will be connected to sensors outside the vehicle. So whenever the driver presses the horn, it will first calculate whether there is anybody within a pre-calculated range of the vehicle, then only it will make the sound. If there is no vehicle around the pre-calculated distance, then the horn will not honk, but it will give a tight slap to the driver. So the driver will always be careful before pressing the horn :)

Nice one no?

Little Einstein

Kavin has started using his "Grey-matter" .........finally!
Yesterday over dinner he kept asking about work-from-home options for doctors. His dad told him that it's not possible since the doctors have to see the patients and observe their condition to evaluate the sickness. Then he said that a device can be made which the nurse can use to check the patient up....this device will check the patients eyes, tongue nad measure heartbeat, temperature, blood-pressure and maybe take a blood-test and the doc can see the results (and maybe the patient also using a camera) immediately sitting at his home and then he can advise the nurse/patient about the treatment.

Cool naa!!!!
