FM Radio Hack (Dirt Cheap) 

EU AND US!

lol

Honestly “Sine Wave” sounds like a 1980s synth new wave group and their debut album “1 kHz”

@@loganbaileysfunwithtrains606 Pure music!

Topped the charts but as soon as it appeared hit rock bottom 😢

FCC says it's OK as long as the power isn't too much. If it's within limits, the effective range is only a few tens of meters.

Just to add to user2C47, there's FM transmitters like this available for non-techies like you and me. They're all over American discount stores like Ollies, Five Below, and Big Lots... because they're meant for people who have cars (or moving vans) that only have radio tuners (without a audio cassette slot)

@@professionalelectronics3158They make them for Bluetooth too. Connect to the thingy with Bluetooth, tune your radio to the proper setting, and it’s like your old car has Bluetooth

i have no FFC in my country, win win!!

You’re way more likely to get into trouble blowing up the citizen band with a overpowered short wave transmitter than you would with one of these 😂

Lol

I'm crankin my sine wave

How dare he do something and not get taxed millions of dollars for it!

Omg exactly what I was going to comment! Every day, he gets a millimeter closer to being like 5 Minute Crafts with these loose definitions of "hack"!

i've seen people staring at me when i plug in some cheap FM dongle to my MP3 to play on the stereo. «IS THAT LEGAL? YOU CAN TRANSMIT OVER A BROADCAST?» literally, yes. and I even did it years ago rickrolling a football match in a building with a VCR's coax output. Now with DVB standard, it's going to be more difficult. BUT HEY wouldn't it be cool to have some HDMI dongle that transmits the video of your PC/laptop/console into DVB-T to any screen/TV you want at home? I should make something like that for cheap.

@@Diamond_TiaraApple has a lightning to HDMI dongle that doesn’t need Wi-Fi to work, I use it almost daily cause I don’t have Wi-Fi for airplay in my tv, maybe that could be a step in the right direction

@@anattempttomakecontent776there is nothing special about a lighning to hdmi dongle.

I mean it worked, it was a hack against your brain, you commented on this video improving its 'engagement' in the algorithm. People are only rewarded to say more assinine stuff in titles n thumbnails this way, but personally find it hard to blame this individual channel

Them not 24/7-on days. That wasn't all too bad.

Is that specifically to do with the Bluetooth module or is it using some other part of the phone to do it? Phones can take microphones on the 3.5 mm jack so couldn’t it just be using that functionality with the headphone wires acting like an antenna?

@@conorstewart2214 It's specifically the Bluetooth module. If you want to know look up the Bluetooth module in a HTC M9 and then get the data sheet for the Bluetooth module and you will see its capabilities

Quite a few devices use the headphones as an antenna, I even accidentally made an am radio receiver by touching the metal part of a potentiometer on an old amplifier that came from some speakers. Tbh am is very simple, you just need a band pass filter.

like, rewriting the driver to operate on the low VHF range? I learned a thing, I think it is fake unless a certain access to rewriting, hacking, modding a BT driver... buit I hope it is. that sounds neat.

@@Diamond_Tiara No, this is a feature that is built into many Bluetooth chips, but not very well known and not very well documented. Look up the Spirit FM Radio which can be used on Android phones with capable chips, or as in HTC phones a replacement for the stock FM radio app. The replacement apps need root access as the OS isn't setup to use the FM but the drivers are already capable. HTC devices Android build is already setup so no root is required, unless you want to broadcast FM signals from the device. Read over this thread on XDA spirit1-spirit2-real-fm-radio-general-thread Here is the datasheet for the Bluetooth chip BCM4356XKUBG found in the HTX M9 and the Google NEXUS that has FM functions built in and the datasheet cover the use and operations of it. alldatasheet CYPRESS BCM4356XKUBG

Link?

​@@gooidoekoe3631there these things called search engines, learn to use them. Most RU-vid channels disallow to post links in the comments for obvious reasons.

​@@madmax2069most humans nowadays depend on others

@@gooidoekoe3631go to any autozone and they'll have a bunch

Same here. Those Bluetooth FM transmitters really work. I can't find them in stores anymore, so now i can only get them online. Good thing about it is that mine has luckily lasted for a few years up to this point. Definitely worth buying if you don't have Bluetooth or an aux port in your vehicle.

Hi, where can I find the schematics? Thank you 😊

what is radio shack?

RIP Radio Shack. Loved that chain!

@@supremeleader5516 Oh my god.

@@supremeleader5516 A old electronics store chain they were amazing apparently sadly never saw one personally

It does happen. As many others have mentioned, it's fairly common to use an FM transmitter to send audio from things like a cell phone to a car stereo that doesn't have inputs like audio jacks or bluetooth. Those transmitters often use either very low frequencies or very high ones, and by a coincidence some radio stations that I listen to tend to be found very low on the FM band. So every so often when I'm driving in traffic I'll cross paths with someone using an FM transmitter (we usually call them "FM Modulators" when talking about this application) . For just a moment I hear the music or podcast or whatever the other person is listening to. The signals aren't very powerful and don't go very far, so unless you find the other car and nearly drive next to them you won't hear it long, it'll come and go giving you only just enough time to notice it and hear the general nature of what the other person is listening to.

Probably not only in UK

I'm guessing just like in the US, you can broadcast as long as it's below a certain power level and it can only be picked up from a few feet away.

@@chitlitlah I don't know what the rules are in England, or Germany for that matter but I thought civilians could only transmit on certain frequencies? I suppose doing it for a few minutes for a RU-vid video you'd be fine either way.

@@laernulienlaernulienlaernu8953 Here in the US, you're able to broadcast on the AM or FM band without a license as long as it's under, I think, a quarter watt. That's maybe enough power to make it to the other side of your house, but that's about it. That's why those FM transmitters are legal, the ones you connect to your phone or mp3 player and pick up with your car radio, in case you don't have an aux port. I would think most countries would make such allowances.

Overregulation. If the power is only a few mW, and it isn't interfering with anyone, who cares? I could see interference being an issue in an apartment building within a densely packed city where the bands are densely overcrowded.

there's plenty of diagrams on the net, even accidentally you could transmit something in LW/MW band with a ferrite coil and the output of some speakers, but go check online, even you can do it! >but i need to bui thing

@@Diamond_Tiara Thanks for tip, I am well aware of that, and have built several including some valve stuff that uses voltages that would terrify you. I would just like a nice simple high quality AM kit that will transmit decent quality audio, seems to be a lot for FM but not much for AM. An yeah go figure sometimes people just want to buy something.

@@RC-nq7mg it's funnier to DIY electronics, I only do it when I can't have things like, a >Bluetooth DAC or some taiwanese silicon. but yeah. tubes are something else, i had a Marshall guitar amp that had a heater requiring around 100V. better not kick that thing. my brother borrowed it and i never seen it again.

There's a few of them, and some that'll do C-Quam AM stereo.

@@madmax2069 yes, itr was a good idea, but FM sound is more clear, and less noise unless you pick local. also FM over shortwave should have been a major upgrade, for quality of transmissions, even across the world, you'll never saturate the SW band with wideband FM even if you pack em all from 5 to 25MHz. And even could have room for RDS. Anyways China would fill it up with propaganda.

I was a big 800Hz fan because 1kHz, it sucks.

I like 120hz more.

he added an antenna

Not really. Very short range because its low power

Not if it is a few mW and has a small antenna.

Oh yeah, I'd be damned to get my hooves on a /k/ommando tier Panasonic DR29 radio, even if it's just for decoration, these are badass!

In most countries LPFM is unlicensed and legal 5v with a dinky wire for an antenna is not pirate radio material

I've done it. It sounds more like one of low parts count fuzzes recommended for beginner pedal builders.

he added an antenna!!!

The board designer couldn't remember the term AUX, so it's MP3
