Wi-Fi Toys: 15 Cool Wireless Projects For Home, Office, And Entertainment

In my childhood days, there was no internet yet. Television and radios were the most advanced communication devices. And that time, I usually had read several books like Thate Pan (Science) Magazines and Thu Ta Swe Zone (Wikipedia) from my school library and too interested in radio and television broadcasting and receiving technologies. But, as of I was living in country side, and there were nobody who could teach me such subjects and did not have books to study such kind of subject, the result was that my hobbies were not properly grown up.

By that time, there was only one TV channel in Burma, MRTV and it usually transmitted in the evening only. We can receive those signals in the evening only. One day, I tried to build my homemade television antenna which can receive satellite signal. I took old 7/029 cables and removed the insulations to get copper wires only. When I got a few numbers of copper wires of about 1 meter length, I tried to make it mesh look alike to satellite receiver dish. I took one 7/044 cable and take out copper wire and put it in the middle of the mesh as I saw on most of the LNBs. Rear part of my own receiver dish, I took one small tin and tied it nicely. Ok. Its appearance was quite similar to the satellite receiver already.

My next step was to find out long bamboo because I needed it to put it higher in the air. Usually there were a few long bamboos with flap and hooks in every house in country side which meant for fire preventive measures, so that I could use that bamboo in my project. I tied my receiving antenna at the top of that bamboo and connect the antenna with old, long coaxial cable to connect to my B/W television in my living room. Installing my antenna was done. Next step was to tune the television frequencies. I turned my TV on and tried to tune. It was a lucky day that I could receive TV signals from neighbor country, Bangladesh. They were transmitting sport channels; I could even watch the football matches even though it was not so clear. But, as of lack of knowledge of electronic engineering, I didn't know how to boast signals, how to filter and reduce noise, how to make antenna more efficient, my own satellite antenna project was ended up in that stage.

The morale of the my own story is that there were a lot of things we want to create, we want to try in our childhoods, but as of lack of support and guidance that can give us a hand to move ahead, our dreams and ideas were faded away. One of my friends who I met in high school, he also tried too much to build up own helicopter in his home. He had collected so many books regarding to that subject and he even built up own toy airplane that can run very fast on the horizontal plane. He used dc motors from walkman cassette player as engine for airplane’s propellers. He tried several times, but his airplane run very fast on the horizontal level, cannot go up to the air. The problem was that the running speed produced by the motor cannot lift up its own weight into the air. Finally, he gave up. The final conclusion is that the normal dc motor won’t be able to use as propeller engine if we want airplane to fly up.

Today, we can see some toy helicopters with DC motor that can go up into the air; I thought that the motor assembly will be different from the ordinary dc motor. Now he was working as seaman already. His dream was to be an aeronautical engineer but ended up with the seaman profession.

Until now, sometime we are trying to play with such kinds of electronic equipments in our environment. I hope that some of my friends will also like to play around like this. For those who want to play, this book is for you.

I still have not received my replica watches sale and the bogus tracking information tells me nothing about where it ended up it says the item has been signed for and delivered. I would like a refund I have no more patience for this. I am calling my credit card tag heuer replica and opening a claim on this company for a replica watches if I do not get a response. This is rediculous. My replica Rolex Yacht-master arrived today at my UK address it looks and feels great but I am a bit disappointed I did not receive this in a rolex replica saleand I have no Rolex certificate as I am rolex replica sale this was included in the sale. The chronograph features appear not to operate I.E. the second hand- the ten minute timer E.T.C. do not appear to work. Have I misunderstood the details of this sale ? I did expect all functions to work. I have also bought the same replica watches sale addressed to my U.S.A. address as a gift so I am awaiting feedback from my son on Rolex replica when it arrives n the USA.
