Long-Range Walkie-Talkies using a Raspberry Pi Zero (including Clubhouse Clone)



Today, we will build Walkie-Talkies with an enormous range using a Raspberry Pi Zero. Cool stuff! Let’s start and build one or two of them. BTW: They can also connect to smartphones and PCs.
If you stick around till the end, we will create our own Clubhouse clone using this technology. Only on invitation and only for the first row, of course!

    My daughter's walkie-talkie talks to my wife's cell phone hotspot. My walkie-talkie talks to my cell phone hotspot. Now I can talk to my daughter without calling her on the cell phone. My wife can be using her cell phone while I am talking to my daughter on the walkie-talkie.

    With most makers being so energy saving conscious, what about a tutorial on energy measuring devices using ICs like ADE9000?

    I think we should also look at the LoRa integration and voice to text to voice making a complete system which can integrate into full secure communication system outs use of Ham Radio which we cannot encrypt.

    Very disappointed that this is just an internet walkie talkie. I was expecting it to communicate peer to peer, not over the internet. The title is quite misleading to call it long range when it is just using the internet. If you need a wifi hotspot on your phone then you may as well just download mumble on the phone instead.

    The fact that this requires internet connection is a letdown. I was hoping for a p2p rf communication.

    Is this real can you just load those two SSH and wpa_supplicant.conf files and the pi's will just work? No having to configure with a keyboard and monitor? God I know nothing about programming.

    Cool project, but I don't see the advantage over a conventional smartphone

    I've built this using the image and I'm getting occasional choppy audio from the Pi (it is fine receiving). Wondered if anyone had any ideas.

    The only thing withholding me is that I have to learn to speak with a Swiss accent when I use that Walkie-Talkie. I must quickly practice some Swiss words: Rolex, Credit Suisse, Julius Baer. I think I got it now.

    Dear Andreas
    This time your tutorial is a little confusing, which is either very unusual, or I am a real beginner.
    1) The command 'cd seed-voicecard' is misspelled (missing an 'e')
    2) With your pre-made SD card configuration, the command 'arecord -f cd | aplay' cannot be typed
    On my keyboard, the '|' key gives the character ~ and the no other key yields '|'
    How do you configure the US keyboard?
    3) How do you chose the right server for the mumble app in my Android phone (Mumla)?

    Can you please reply here or to my email <rpensotti@yahoo.com>
    Thanks

    Roberto

    Great project!
    I have a PI 0 W but not the HAT so trying this out has to wait and that's no fun. Would it be possible for the mumble client to connect to a BT headset instead and thus remove the need for the HAT hw? That would be perfect for my application – a small intercom system on a sailing yacht- we already have some rpi's (3 & 4) and a local WiFi for mqtt and signal-k/NEMA communication so adding a few rpi 0 w's as communication clients would be a no-brainer. Have to look into this but will order a few hat's tomorrow just in case.

    Looks like not every "8GB" card has exactly the same size. Mine (intenso) was a bit smaller then your image. Trying another one I find that the folder is named seeed-voicecard (with 3 'e'), looks like a typo.
    For some reason arecord cannot open the audio device. Maybe I have messed things up by updating the software and playing around with raspi-config. Will start again now 😉

    To make it a go-anywhere device, you can link it to your smartphone. Or, you can, you know… use your smartphone. 🙂

    Still a cool and fun little device, and a good starting point for even more advanced projects.

    I like the project, but for me the special feature of the walkie talkie is the freedom and independency, can be used anywhere and needing nothing other than at least 2 devices and energy.

    How about adding in a camera with motion detection. Then you could use this as a security camera. …or in my case i want to set it up in the woods and take pictures of animals. Would like to be able to drive somewhere close and download the pictures without disturbing the wildlife. So this would appear to be half of my solution?

    Good day! This is kind of off topic but I need some help from an established blog. Is it hard to set up your own blog? I’m not very techincal but I can figure things out pretty fast. I’m thinking about setting up my own but I’m not sure where to begin. Do you have any points or suggestions? Cheers

    I have figured out some points through your blog post. One other stuff I would like to mention is that there are lots of games that you can buy which are designed especially for toddler age kids. They consist of pattern acceptance, colors, family pets, and shapes. These usually focus on familiarization instead of memorization. This keeps children engaged without sensing like they are studying. Thanks

    I’ve learned new things by your site. One other thing I’d like to say is the fact newer computer system operating systems often allow additional memory to be played with, but they as well demand more memory space simply to run. If one’s computer cannot handle much more memory and also the newest computer software requires that memory increase, it might be the time to shop for a new Personal computer. Thanks

    Howdy would you mind stating which blog platform you’re working with? I’m looking to start my own blog soon but I’m having a difficult time making a decision between BlogEngine/Wordpress/B2evolution and Drupal. The reason I ask is because your design and style seems different then most blogs and I’m looking for something unique. P.S Apologies for being off-topic but I had to ask!

    Hmm is anyone else encountering problems with the images on this blog loading? I’m trying to find out if its a problem on my end or if it’s the blog. Any feed-back would be greatly appreciated.
