This gives the vibe of an inverse version of Bird and Layzell's evolved radio. Minus the evolution, of course.

does it work with c++?

Hey man. I really appreciate your videos. I truly believe that your channel is underrated. I'd personally love to hear more often from you re your projects, discoveries, ...

The links You had provided are dead... =[

I teally want to port a C program with UI in raylib to android... so I find myself here .

Now remake the entire video in english please 😂😂

thanks, this is exactly what i need, but i want to know if its possible to run on those really old android like 4.4?

whats the app and hw for spectrum display at 7:07?

Thank you very much for making it open source, I will try to use it for my own project that takes a low-res digital video from USB and converts it into analog. My version will be PAL as I live kn europe. I just have to wait for my ESP to arrive.

esp32 has DACs and Sigma-Delta Modulation. Any plans to implement this on esp32? Guess the results will be way better.

Back again

Amazing video asides - The security implications of this being able to be performed on commodity hardware are pretty terrifying!

this looks like minecraft but highly cursed

I like the use of Tiny C Compiler (tcc) and using radraw with it! I recall you made a bare-metal app for Android written in c..no java.. was that also using redraw? BTW, if you're developing for Windows, any reason why you wouldn't start with the free Visual Studio 2022 Community IDE instead of Visual Studio Code editor? Does the tcc/mingw compiler work better? Regarding overlays, any thoughts on Augmented Reality? I've seen some cool applications like inspectAR (Cadence) or "Augmented Reality BreadBoard circuit building guide". I imagine using TiltFive (formerly CastAR) which support Unreal and Unity one could make these types of applications?

I wonder, really possible to remove out this plastic glass on late release base stations, using vacuum suction cups and heating joint between glass and rest of case?

how the hell did you fit a usb stack inside the boot sector lmao

Can doom run it?

Wait, what do you mean by "-175C (at 900MHz)" ?

If there were a hall of fame for filthy, sleazy weapons-grade jank, you’d deserve a whole wing

All links are 404 not found😢

Wow this is some serious back magic fuckery. I love it

yoooooooooooooooooooooooooooooo thats so outside of the box thinking!

So basically I didn't understand any of the techie stuff but I watched the whole video for the captivating "pirate radio" innovation. This smells of freedom.

💖💖💖💖

This is so hacky I love it

What font do you use in ubuntu like terminal ? 😅

This was an amazing project and you are a brilliant engineer. You mentioned your dad was a “true EE” so I assume you are not one. I have a MSEE and worked in the RF industry. Let me tell you sir that you would outshine most all of the engineers I’ve ever worked with. I cannot recommend enough for you to get your EE degree - it would be a breeze for you. Our country needs brilliant engineers like you!!!

what font is being used in linux here?!

:) There are a lot (incredibly many) links in this video.

NSA disappointed this is getting out.

Nice work. I've been developing 'cross platform' apps using Xamarin Forms for a number of years. But tbh I've never been satisfied with a lot of the options, just as with web development I feel everything is so overcomplicated and needs you to redevelop apps every few years which is exhausting. I'm a bit fed up with Java and C# /.NET and all the frameworks built on top of them and this is how I found your video. I'm not a C programmer although I did a bit of C and C++ when I was learning. I might give this a try. Do you know if there is any way to use native UI components?

my jaw is on the fucking floor

It's truly baffling that after 8 friggin years after this video was released, people still come to seethe at Charles' personal life choices as if they were of any consequence at all to the people seeing the video. Some people even saying that they "didn't like religion being brought into the channel" are you people for real? Have you got no shame at all? As if it was your prerogative to communicate such thoughts instead of keeping them to yourselves, as if you had the right to push a man toward changing or hiding an integral part of his life simply because you're too childish to accept others' dreams and prides? This guy, like many others, has given immense amount of knowledge FOR FREE to the whole world, driven by his own passion for sharing and discovering, and you people have the audacity to come to him to angrily vent your own rebukes and ask him to change for your own benefit? You people should be disgusted at yourselves. Learn to comprehend and admire others for what they are instead of trying to trip them into feeling guilty of your own prejudices. FFS

awesome!!!

One improvement I would add is getting an RJ 45 connector with the built-in magnetics as makes it smaller

I work with LoRaWAN in my day job. This is the coolest thing I have seen in a long time 😂 Bravo!

*The concept is SO COOL!* I have used a website about 10 Years ago, that used a Java web application to Transmit Audio to a AM Radio (I think, maybe it was FM). It used CPU EMI. 😮 (Sadly can't find it anymore) Security researchers also used GPUs to get data off of Air-Gapped systems.

You CMAC code is chef's kiss! Thanks man!

The military industrial complex would like to know your location.

I wonder what you could do with an Arduino MKR 4000 Vidor

This is freaking awesome. You can essentially create the baseband using a cheap micro + 900MHz SAW + gain block. BTW, it's "megacycles" not "megasamples".

You need resonant output lc filter to suppress other harmonics and leave only desired frequency.

I understood nothing but good job magic man

I don't think java is a bad language, I just don't think it is good for me.

Every now and then I come back to this video and think about making one on my own. It seems Waveshare actually started selling a 7.3 inch version in a wooden picture frame! They sure know their audience

Wow! i kept skipping this video cause i thought it would just be opinion and reaction style youtube garbage. this is WAY cool! like genius cool! my mind is blown

i reached 90km with 2 ttgo and direct line of sight (from mountain to another mountain), some reached 400km+ with weather balloon

16:50 That's because Nyquist ist always explained incorrectly, even in academic literature. The original theorem clearly says "bandlimited signal" meaning bandwidth and included different Nyquist-zones that can be used for sub-Nyquist sampling. The only condition is that the bandwidth of the generated or sampled signal is smaller than fs/2. And many people don't seem to understand this.
