hi.... may nag.suggest kasi sakin!!! di2 ko daw mahahanap ung sagot sa tanong ko... ???
magagaling kc daw ung Electrical engineer d2 eh....

possible po bang ma-transmit ung 5 volts dc via wireless dun sa receiver circuit ko para pang supply sa microcontroller?possible po ba?
mga 1 meter or 1/2 meter lng ang layo galing sa tranmitter dun sa receiver circuit ko!!!

ang alam ko ay microwave ang tina transmit para magkaroon nang power sa receiver.

'yung sa MIT 10MHz pero not transmitted the same way as RF.

'yung sa RFID naman nasa 125kHz ata. pero mababa lang 'yun. just enough to power the IC.

yes.. masyadong mababa ang power ng RFID.. based on what i have read parang transformer ang wireless power transmission kaya lang with "resonant frequency" para maiwasan mag-spread out yung field.. take note na ang transformer with primary and secondary winding is a form of "wireless power transmission" kaya lang at very short range..

I wish for this night-time to last for a lifetime
The darkness around me
Shores of a solar sea
Oh how I wish to go down with the sun
Sleeping
Weeping
With you

I walk alone
Every step I take
I walk alone
My winter storm
Holding me awake
It’s never gone

I fear that soon you'll reveal
Your dangerous mind
As your true colours show
A dangerous sign

Pwede if just small amount of energy by means of Radio Wave (RF) but SA MADALING SABI MGA PANYEROS THERE'S NO IDEAL WAY OF WIRELESSLY TRANSMITTING ELECTRIC POWER (I WOULDN'T BE TALKING ABOUT TRANSFORMER IN HERE) - NOT A SMALL CHANCE OTHERWISE IT'S POPULARITY CULMINATES A THOUSAND FOLD! - magkakaroon na ng power producers from outer space enough to transmit power for users below hehehe - nice one but a too good to be true.

mangangailangan ka ng malaking loop antenna para sa malayong distance at malaking power.


curious lang ako sa invention ni tesla na 10Hz, wala pa nakapagprove nun. ???

planning to make one... maybe next year.. kailangan ko pa ng financers.hehehehe    I'll start with a small tesla coil.. Ive already made a small van de graaff generator.. gumagawa na sya ng mga small sparks.

According to the theory, one coil can recharge any device/coil that is in range, as long as the coils have the same resonant frequency.
alam ko po naprove na yan ng MIT(massachusetts institute of technology) team nung 2007..
WiTricity title nila sa thesis nila naun..

Buhat ng madiscover ang radio wave propagation naprove na po ang concept na to,
