Mobile phone flasher
(OP)
Does anyone knows how to build a mobile phone flasher?
I guess it has some sort of coil which transforms the waves in power, but I haven't found out how.
Thanx in advance, Carlos Cardoso

If the light source is neon or similar, then it might be using the RF itself to fire up the light. Last evening I was unpacking a new neon novelty light ("BAR") and every time that it rubbed against the styrofoam packing material it flashed. It doesn't take much energy to fire a neon, but it does require at least about 70 volts (a cell phone would require some sort of step-up transformer).

I've never paid close attention, but aren't those novelty antennas used on cell phones non-battery powered? From what I could see in the packaging, you simply replaced the stock antenna with that one, no wiring necessary, which to me means no battery connection and all power comes from the RF.

I can think of a few people who would carry cell phones around even if they didn't actually make a call... just because they look cool doing it. There were the days (late 80'of fake cell phone antennas for cars

It's like this, My new office will be a bit noisy, so I'm planning on working with some sort of headphones on my hears. Since the headphones will most likely damp the noise from the cell phones ringing, I thougt on doing a gadget that will flash a light every time the cell phone rings.
I've seen some gadgets of this kind and I'm almost sure that it doesn't have any sort of battery.
Thanx and merry christmas! ;)

Seems like you need to visit your local shopping mall and drop by the booth that sells such cell phone gadgets.

When my phone rings in the car it "screws up" the sound coming out my stereo. I discovered this quite by accident and it has been very useful when the volume is way up on my stereo. I simply leave the phone near the radio on my dash and I always know when it is ringing.
Try setting your phone on top of your computer tower or near your laptop and hear what happens when it rings, maybe this is a simple solution for you and it doesn't cost a cent.

It's not the flashiest solution, but... It's a solution :P

Any sign (or not) of a small battery?
RE: Mobile phone flasher
I would be interested in exactly how those flashers do work though...

If you have an old non electronic phone, place a cell 1- feet away from it, while you are talking in the phone, let tthe cell rings, (like calling the cell number from other phone) , you will be surprised of what you will hear on the regular non electronic phone, picked only by the wired driving an old ear piece no amplifiers no power source of any kind. I was shocked when I heard the picked noise are greated that the sound received from the other end
