Companies internal TV transmition

Abbabbj

hello all
i had a simple idea 3 years ago it state that we could get a PC add to it a TV out card (A/V out) And use a single band 100 watt VHF transmitter (70$) for indoor analog TV transmition it would all cost about 100 $ (without the PC) and it has a range of 100 m (more than that would be illegal)
uses of such devices are numerous ex: electronics and TV shops
government agencies
Companies ...
anyway i was 15 years old so it may seem silly but i every week i have a new idea(most not telecom related) for example: the use of ************* in elevators
delaying menopause
improving whitebords
new materials in construction
....................
but in our society i am always faced by ***** people who only live to smoke nergiele and to be just like most Lebanese (beyhebbo 2el mazzaher ) ******the Lebanese univ and also our government

(maybe the situation near you is different )

i had the schematics for that, i hope i'll find them coz it dates back to at least 5 years.
it just needed audio and video in (RCA) as inputs, hope that's what you want.

100 watt will bring TRA to your office and huge fines
100mW is fine, but most of transmitters - analog

I welcome any idea you may have , and help you develop it ( electronics related ) .

A friend once showed me a cheap spy cam, it's a little cam that you would hide somewhere, and it would broadcast on TV frequencies, and you can see the image on a TV in a nearby room.

Hmmm that reminded me of American Pie.

thanx all for your help i am actually capable to construct such a device easly but what would i get other than(3am betdaye3 wa2tak \leek hayda shu ahbal\shu betheb tosrof massari..... )
any way i dont care ,every day i have a new idea and i always try to improve things invented long time ago(ex replacing our hordi walls with 2 carbon fiber plates with a fiber glass insulation between them) but unfortionatly all my ideas are not applied(No one to hear from you) i am sure that after i get my phd abroad then i will be capable of doing any thing i want but thanx again for your help
And jad do you know any place where i can learn PIC courses during summer?

internet is your best friend , find a guide , get a programmer , build a platform and start experimenting :) !

A piece of advice?

Start working on your ideas. Pick one and do it. NOW! It's a thousand times better to have just one idea and finish it. I should know. I never act upon my ideas, and realize now how much time I've wasted.

Once again, better work on a tiny project than think about great ideas.

thanx rahmu for your advice but what will i do if i finished a project?
For example i have a solution for elevators problem in poor countries where electricity is not avialable all time i can make a demosntration for less than 1000$ making the elevator totally indepent from electricity and more energy effiecient (i also have a way to delay menopause for 20 years but it is just in theory i will experment it next year and i also have an idea to make a 360deg screen from single LCD screen with its own cam but i think we dont have the technology to make one right now[other than that sony invented another principle] i also have an idea for........... but what do i do when i finish my project ? And lets say i have made a less expensive project like the one i mentioned above (it is so simple and cant be cosidered as an invention)any way thanx a lot
And i archive most of my ideas and i search for patents on the web to see if someone has done my idea before and i alaways find that my ideas are completly new
Any way i can get a UHF single band transmittor with A/ V input and i cant get any VGA with video out and audio out from a sound card (but do i need a modulator?) a network engineer told me that i need one but i am not convinced with his idea because i think that the transmittor sold actually contian its own modulator
And 100watt transmision for A\V is not like 10watt transmition of radio (sound only) with respect to the range

Abbabbj , have you made anything yet , or is it just ideas ? what degree do you have ? and do you have the technical background or expertise to do what you are mentioning ?

a network engineer is ignorant about these stuff , he gave you info related to wireless data transmission :P you should take advice from a computer/communications engineer (like myself), most graduating engineers nowadays know shit , if you get a ready built transmitter its going to have every thing you need within it . the thing you are talking about used to be popular in the 80's . main use was to transfer the VCR video signal from one room to the other wireless without using cables and utilizing a single TX and using the UHF/VHF RX built in the TV .

Abbabbj

yes i will use this kind of transmitter i know that it has its own modulator but i think that the engineer i asked i dumb
Any way i havent applied any scientific or tech idea yet but i applied many social projects which had a mass effect on many people life
Back ground
18 years old lu student hadath (biochem)general biology chemistry i will take a BE biology and complete bioengineering in france
I worked as a pc tech in a company for 6 month with school i also took a simple 1 month phone repair course in 2005 which gave me simple knowledge in electronics

J4D

good , if you need any help just ask .
