Does the N.S.A. know this I wonder? Really? They should? They better. 1st place posted in the world.

You can buy really cheap little computers basically on various places on the internet. Programmable chips. With what they call I/O ports. The pin connection can be a input or output. Common everyday speakers, even earbuds type speakers, can be microphone.

Some videos off youtube showing this. Yes little tiny speakers that fit into your ear canal are the same, and at head level. Make even better mics that way.

So when some little device, like a cell phone, or ever tablet, or laptop, or even desktop, has a speaker, it can be used as a microphone. (All have cell phone wireless or internet wireless access) or wired internet access. https://www.youtube.com/results?search_query=convert+speaker+to+microphone

So you can disable your microphone, and even physically remove it. It does not matter. You can still be listened to Generals. Or Mr. president.

The speakers you have can still be used as microphones in reverse. Along with having a little programmable chip that give output directly to a speaker. Then it plays your music or whatever. But when it's quite. That I/O pin it's connected to can listen to the output generated by that speaker, like it's a somewhat poor quality microphone.

Even if the output from the computer chip pin, goes to audio amplifier. Well that audio amp chip to, can be manufactured to work both ways. As a audio input/output device using the speaker to as the transducer. Just not tell you about it. Simply by activating some code, built into the chip even (BIOS), by sending a special packet by wireless or wired means. Even cameras can watch for a patterns, that activated this feature. Like a BIOS on a motherboard loaded, waiting, running, watching, listening.

Like watching for QRP codes or bar codes, but not tell you. Then the device when activated, sends text files of recorded audio conversations. When the camera sees no one is around for example, or while you make a call, or browse online, use email. On a regular and routine basis. To one or more ip address online, people use routinely or the computer uses itself. Extra data being sent. Can be hidden in normal data flows. Called stenography in the IT security community. Well when done like that.

This also means, any type of digital optics for example (digital processing) can have code like this running, and the optics see a pattern, and shut off, and never turn on again. Bricked forever, unless fixed at a factory, or shop, or something. Replace dead chips, maybe other parts too. The optical sensors themselves bricked. That part in tanks, jet fighters, rifle scopes, etc.

Digital security cameras, are connected to all kinds of high security systems, including at the white house, and the pentagon, the police, the military, and such. They are everywhere.

Maybe digitally processed (real world signals to digital world signals) RADAR and SONAR too can have the same problem. Easily Bricked or whatever. If you can not see like a picture with RADAR or SONAR. Hidden code can do all kinds of bad things as the operator monitoring has a much harder time then detecting something being wrong.

You may have seen in a sci-fi movie, a police officer, flashing there badge, to a camera, at a persons home, and be let in. The same type if thing basically. Doesn't have to be a camera. Any type of receiver and have this done. A camera is a receiver. Lots of things are. Mics, antennas, cameras, video cameras, radio telescopes, solar cells, photo transistors and diodes. You TV has a IR receiver, and maybe internet access, and a speaker. You microwave oven, if it can make a ding noise, has some type of speaker. Is it internet ready? Is it wireless?

Digit signal can be sent over power cables and the power grid, in some cases, and places. To one degree or another.

I think government agencies have built-in these types of applications to various CMOS chips, so yes it's very possible. Consider having a few lead-lined bags for keeping electronics in, the same time we used to keep 35mm film in when traveling abroad.

If they can store what you say as a text file. As soon as you take the device(s) out of the bag or you make a call or whatever. The stored conversation as text, can be uploaded in a few packet. Less than 1/10 a second.

Having the device in another room or far away from you, is a solution. Along with some noises. Like a AM radio tunes into static, and turned up, so you can hear the static. Along with volume being turned up. Etc. No power. Having a removable battery, and keep the battery out for weeks, to months. Or not anywhere near you, or others.

So a foil bag, with sound absorbing material, as a liner, is also critical. Maybe with a noise maker (music player) playing inside the bag, at the same time. If you want to carry one in a secure manner. Will not receive messages and such then. Still can, if it's far away, turned on, outside a metal foil bag.
