shadilay brother, so if pi zero can transmit FM radio then what else could it transmit and how does it do this ?like if you wanted to control RF things 2.4 Ghz you still wold need a super hetrodyne right? i wonder if this would be able to be used for some car audio projects , plug your phone into the USB and play MP3 on your phone through your car stereo maybe add a mic to the GPIO pins and a button and maybe a bluetooth dongle or a way to get audio out form the 3.5mm jack to the pi
Anyone here from the Lone Survivor's Director's radio? that allways made me interested since in the case of a cataclism or an event,you could just transmit stuff over the radio,so the survivors are hearing it,good stuff to see,this pi radio really reminds me of that,good job,I'm subscribed now.
You will not be able to reach 2.4GHz, however, you could possibly use an upconverter but you would end up spending a few hundred bucks when you could buy an actual SDR for the same price. However yes you could transmit for listening on your cars radio, however, you'd most definitely would need a license for it to be in regulation.
"I will only do if for like 10 seconds" -running for about a minute -I earlier tested the range about my house Definitely only 10 seconds :D But great Video!
Do not underestimate the range your signal can travel. A Raspberry Pi with clean filtered output using a ham radio mode called WSPR has been heard over 5055 miles away on 14.0971 Mhz! It would literally take just an extra minute to make a primitive bandpass filter from some scraps of cat6 wire. Cat5/6 has a capacitance of 15pF/ft between the wires in a pair. To make an inductor wind 7.5 turns around a pen to make a 400nH inductor, then take 4.8 inch of a pair and connect the same color ends together from that wire (Blue-Blue, White-White) there is your 6pF capacitor. Solder it to the end of your inductor. This will form a simple Bessel bandpass filter that will reduce harmonics by -10dB for 0$ However you would need -43dB to use one as a real transmitter and that will take more than some cat5 scraps. Please take some time to learn about RF before you go transmitting with this kind of thing. You can unexpectedly do great harm and get yourself in lots of trouble. You should also look into earning your amateur radio licence. The test is not that difficult and there are a whole world of frequencies opened up for experimentation if you get a licence. It is the best hobby in the world.
Nathan Trone i am not sure but he may have used the usb connection to share his pc network and he ssh'd into it. or he also may have just used the power from usb and sdh'd normally
Flash Raspbian onto the Micro SD. Mount the boot partition, edit cmdline.txt and add "modules-load=dwc2,g_ether" behind "rootwait" but before "quiet". Make sure to use Notepad++ as it will not break the line endings, and don't add any new lines in this file. Next, edit config.txt. Add the line "dtoverlay=dwc2" at the bottom. Lastly, shift-right click in the folder, and click "Open command prompt here". Type "copy nul ssh", enter, then "exit", enter. Now, put the SD into the PI and connect it to your PC via USB. Install the "Bonjour Printer Service" software, restart the PC. Open PuTTY, connect to "raspberrypi.local". Boom. Connection made! If you want to let it access the internet through the USB port, make sure you can connect to your Pi over USB and that it is recognized as an RNDIS Ethernet Gadget. Now, open the "Control Panel", go to something like "Network- and access center", on the left choose "Change adapter settings", select your main network, right click. Properties, then choose "Sharing" (or something like that) in the top, enable connection sharing, and select your Pi Zero's emulated ethernet adapter as the target. You can now access the internet on your PI. If the connection fails and you can't find something like an "RNDIS Gadget" in your Device Manager (devmgmt.msc), download the Acer RNDIS driver from the Microsoft update website. Now, press the Windows key, type "devmgmt.msc", right click the device manager, run as administrator. Look for "Serial Devices" or something like that, find something along the lines of "Serial USB Device", right click it, update drivers, choose a file from the pc, let me pick, choose the file you downloaded (extract it to a folder and choose the ini file in there).
Hey, I just discovered your channel and wanted to say that it is absolutely fantastic! Your videos are very detailed and easy to follow. Anyways, keep up the outstanding work! -Max
I tried this out and it works, but my goal was to transmit an internet radio stream. However, I couldn't get it to work. I was getting constant errors about the wave header missing, whenever I used SoX. Then I thought of a different and possible better method. I installed Pi MusicBox and used an aux fm transmitter, which I bought years ago to use on a car radio. I extended the range of it by soldering an antenna to the board. Now I can stream music and internet radio on my Pi and transmit this to my old tube radios. Multiple benefits: no unwanted harmonics and an allowed signal. Meaning I won't interfere with any other frequencies and the signal itself won't leave my apartment. The sound quality is also a lot better using this dedicated transmitter. In the future I might buy a HifiBerry DAC to further increase the sound. Another good idea might be to build a transmitter from scratch to have more control over frequencies and a knob to control signal strength.
I've tried this a few month ago. I used a USB soundboard and transmitted the mic input to FM. This way I can just connect my phone to it. The only problem was the quality. It's a nice pi project but for constant use, I'd recommend an FM transmitter from Amazon. They're like 10 bucks.
where is the link to the fm transmitter software??

"these peaks..." are harmonics of frequency you are transmiting. please put some simple filter on the output, otherwise you will polute spectrum with hamonics, which can be illegal
I think that this could use some filtering and an amplifier, you could definitely broadcast a distance away. Maybe have an SSD full of music and a solar panel so you can play all the time in the woods or something
I know this is an OLD post and all... however, if that is a TRUE spectrum representation, then thats actually transmitting AMPLITUDE MODULATION and NOT frequency modulation!
Using sox lets you stream internet radio to FM, if anyone is looking to do that. Example (This stream is an mp3 stream): sox -t mp3 stream.p4.no/nrj_mp3_hq.m3u -r 22050 -c 1 -b 16 -t wav - | sudo ./fm_transmitter -f 103.3 -
Yes, please do a video on how to ssh into the pi (if you can explain where to get the IP adress and etc.) and I would apreciate you could stay active on those yt comments, it would help a lot guys that have the same question and you didn´t talk about on video. (Love your channel and the camera is a good improvement!)
Cool ! Thanks :) ! Just one question : Where do you buy your stuff (pi zero, arduino, etc ?) Cause it look like you have a lot of them ! Banggood :D ? And, with which software do you look at RF ?
There are 0.1 watt FM transmitters to buy in Germany. Commercial radio stations have 1,000 to 100,000 watts. Because few AM frequencies are available, everything has been squeezed into the FM band for 50 years. Good luck finding a free frequency there. But little is going on in the 27 MHz CB band. Legal devices are also cheap there.
Hey, can you please make a video on making the radio run on boot? I have tried it like a million times, but i simply cannot get it to work. Thanks in advance
Pi Zero W with in built WiFi released in Feb. Find IP of the Pi, open Putty, put in IP, connect, login with standard login(pi, raspberrypi if I remember correctly), boom you've SSH'd into it. Surprised there's that many people that don't know simple SSH.
love your videos, you have inspired me to get a raspberry pi! I also brought the Raspberry pie projects book so i can try and make lots of things. Please make more raspberry pi type videos.
By Kek's will this Channel has hit my sidebar. I am starting to like RUclips's attempt to get their PC AI together. Not so sure it can cope with the variability of 5h1tl0rDz
Quick question... how would i go about making it transmit WAV files from a particular folder? for example instead of the star_wars.wav, i would like it to play multiple wav files within a given folder. Thanks in advance!
i think you are ok since fm is only 1 of a very redundant means of emergency broadcasting methods so if you drown out your local radio station no big deal because if there was to be an emergency alert tv, cell phone even police driving up and down the streets and air raid sirens are other methods.
Could you research and make a video on how to make the add-on filters that HAM operators use on these Rpi's to connect them to conventional antennae and use them as an actual transmitter station? I have a feeling you will come up with a much cheaper solution then what's currently available. Maybe even another Indiegogo project? I have a concept involving a PiZero with one of the mini RTL-SDRs attached to it listening on the same GMRS channel my Baofeng radios are on for DTMF tones from the keypads on the radios to activate the Pi's GPIOS and or record transmissions and relay (parrot repeater) or record and play back (message system) using this method to transmit but with a proper filter and antennae in place.
No ! Those transmitters emit a sinusoid signal, that is a single frequency. This "transmitter" transits a square wave, which has almost infinite amount of harmonics (multiples of the base frequency) therefore this transmitter is literally illegal by design
Could you use this and write a program to basically communicate between two pi's over a decent distance? making one listen while the other talks and vice versa then maybe play a game of quake over the connection!
Does it take over a frequency? like if our car is listening to 100.7 and I transmit to 100.7 what will they hear? my song, the song that was already playing or just scrambled noise?
The cars radio would pick up your signal, but chances are even if your signal is right there the radio stations will be many times stronger, and all you would hear, is your audio mixed in with the original stations. A faint background noise.
Nice, but only playing one song? How do you get it to randomly get a folder of songs and play each one? Use Python to run the command like and insert the song as a parameter or can you do it in the app source code?
Be careful with them (the wifi variant) when you do. I've treated my well but one of mine completely lost it's ability to use wifi. I looked at it under a magnifying glass and it looks like the wifi chip might have had a tiny bit of damage (literally grain of dirt sized mark on it). They're only $10 online, btw. $5 8 day shipping though.
Hey, I have some questions about the transmitter. I use mine as a 24/7 broadcaster but sometimes it might just stop looping the playlist, do you know how to fix this so it is just a permanent loop? Can the transmitter broadcast multiple signals at once or must I use another pi? and finally could I use a UHF antenna to increase the range? sorry its a lot to unfold but I hope you can help :)
Hi will it work as a prank if im near a radio for instance in a car with a friend and i transmit it to a radio station thats playing or it wont cause he original station is stronger?
This is illegal in the UK for anyone that's wondering. You need a broadcast licence from ofcom to be able to do this. Or you could do this on the ham freq but again you need a licence and is frowned upon playing music on the ham bands. You can however use this to listen to the ham bands if you so choose
@@sixsixsixjet It also will transmit on many harmonics, and these higher frequency signals will carry much faster and will interfere with military airplanes! So no, even with a broadcast licence using this is ilegal!
Just a question. Can you put multiple projects on one pi? SD card wise. Like I want to mix P4wnP1 with this radio project. It wouldn't get rid of the other? I doubt it because it's just another program but i was curious.
This is super kernel depended I ran a pi 3b with the PiFmrds software it works with tweaks sounds great. But on pi zero w with kali linux aloa pi OS you get terrible audio skipping. I wish Aola pwn pi would implement this considering it be sweet to have all the tools available.
Dynamo Drone 300/MHz gives you the wavelength. Divide the wavelength in four. you now have the length of your antenna. solder it to the output pin. you can also attach the same length to the ground pin to act as "counter weight" or the other half of your half-wave dipole antenna.

To improve Sound quality, you can wind a another wire from the negative rail around the Antenna, that will work a lot better.

You can't add a filter, because the lead to the filter is already enough antenna for the higher harmonics.

Is it possible to talk in that radio station, made with the raspberry pi?
Yea
I'd imagine this falls under the same legality as the FM transmitters for car radios that don't have AUX ports.
No ! Those transmitters emit a sinusoid signal, that is a single frequency. This "transmitter" transits a square wave, which has almost infinite amount of harmonics (multiples of the base frequency) therefore this transmitter is literally illegal by design
And how can I modify the transmitter so that its range would cover say 5kms?
so you could interrupt another transmitter with this? i.e. a radio news network or police radios or something ?
Technically yes, however that would be very illegal.
If I use a bigger antenna will the reach of the radio transmitter increase?
Yes, however without boosting the voltage output of that antenna the audio quality will decrease.
Could you use this and write a program to basically communicate between two pi's over a decent distance? making one listen while the other talks and vice versa then maybe play a game of quake over the connection!

Would be nice if you could transmit over Bluetooth over to the PI, or use an AUX cable, rather than using music stored on the pi.
Can you attach an RF amplifier to it (of course, with a filter attached to reduce any harmonics)

for this project does it matter if i use rasberry pi zero or rasberry pi zero w ?
How can i get a larger range ? Maybe like 50 mile radius
This is super kernel depended I ran a pi 3b with the PiFmrds software it works with tweaks sounds great. But on pi zero w with kali linux aloa pi OS you get terrible audio skipping. I wish Aola pwn pi would implement this considering it be sweet to have all the tools available.
Also PiFmrds seems to have less interference I noticed it's not gone but it has other features which I find more useful.
hey..buddy could u help sort the raspberry pi to transmit video n audio over a short distance using ESP 8266 wifi module..!!
Nice choice for a song
Shaliday ;)
could you use a better antenna for a longer range
Dynamo Drone 300/MHz gives you the wavelength. Divide the wavelength in four.
you now have the length of your antenna.
solder it to the output pin. you can also attach the same length to the ground pin to act as "counter weight" or the other half of your half-wave dipole antenna.
I tryed to do that but the transmition is very low and there are too many loud sounds
