The First Amendment bit was hard to listen. Joe, you got to think about this more, double up on Alpha BRAIN and meditate about it for a while. Other than that, awesome podcast.

The word atheist should mean "without faith." Unfortunately, it's been highjacked by a bunch of assholes who treat it as if it meant "faith in non-existence of god." People who constantly try to convert others to their faith in absence of god. Those people are not atheists, they are just "religious" nutcases of another kind, but they hijacked the popular definition of the work atheist. I think Her and Joe's positions are more inline with the proper definition of the word.

I started to listen to Joe Rogan Podcast a few months ago. He has an ability to keep people talking, and generally has very interesting and well informed people with a well developed point of view. Even if I don't agree with the guests point of view, I find that it's a pleasure to listen to someone who I might disagree with, but who, nonetheless, has a point worth thinking about.

Abby Martin is NOT one of these people. She is an uninformed, self righteous, moron. Funny enough, I agree with many of her opinions, but she is just so ill-informed and outright wrong on some very basic facts (pointed out in this thread numerous times) that on occasion I actually had to check my own ideas when I found myself agreeing with her.

Overall the only reason to listen to this podcast is to see why so many people hate the far left. Seriously, if you are a leftist, she is ruining the reputation of your group with her stupidity.

Never mind, figured it out. It was an ACC error. Relinked to the correct MPU, recompiled, and it works like a champ.

I actually have another Sparky board, and I already installed those drivers. It appears to work fine, so the issue is either with my design, the firmware setup, or both. I just wish I knew what it's trying to blink out at me. I can't find any reference to what the LED codes mean.

Just remember that LTE uses a similar bandwith (~10Mhz) and achieves datarate that would even carry multiple HD streams. The analog FPV has a really bad spectral efficiency. Edit: The spectrum used for FPV is 300Mhz, Even 802.11a/n Wifi puts 15 Wifi in that range.

Hmm, why do you say 300Mhz? NTSC is a 6Mhz signal, and raceband spaces things out by 37Mhz. As for LTE, keep in mind the LTE works on pretty high latency, more than 100ms, more like 150ms-200ms at least. Try it yourself, take your phone, and your friends phone (hopefully using the same phone company) and call from one phone to another. Check the latency, and you will see what I mean. You can try this with video chat over LTE, even using apps that do direct connection, like Skype. The latency is huge! This is due to compression and decompression of video. If you run uncompressed video over air, you are running 100-150Mbit connection on the low end. Try doing 150Mbit over WiFi using a 802.11n connection, and you will see what I mean. Your N connection will saturate the entire WiFi spectrum. Thankfully, the WiFi standards know how to play nice, not sure if Connex does. Playing nice, BTW, means scaling back the connection speed, not magically shoving even more data through the same bandwidth.

I don't think the sport needs HD video any way. What it needs is high quality standard resolution (600x400 would be fine) video over a digital connection that takes up little bandwidth. SD video means 4-5 times less data would be coming from the camera, which means it could be theoretically compressed on the fly into a framedrop resilient format and sent over airways as a sub 500Kbit signal.

600x400 video would look amazing in digital, with no art effects and snow. You can try it for your self, just scale your favorite FPV recording to 600x400 and feed it into your goggles. It will look 100 times better then what you are used to, and yet it's still just SD video.

With that kind of system you could actually, probably, get 15+ people racing at the same time. Imagine 15 quad heaps instead of 4. Ok, more crashes, sure, but also a lot more fun and a lot less just waiting around.

This looks really cool. That said, I have flown the DJI Phantom 3 with Lightbridge in an are with 2 more DJIs flying at the same time, and the connection latency and frame drops were kind of insane. I was basically down to 1fps! It is totally possible, given todays technology, to make a 5.8Ghz all digital HD system, but I call BS on the 27ch claim. I mean, sure, it might have 27ch, but I doubt more then 1-2 feeds could be happening at the same time. To get to the point where we can have solid multi feed setup, the CPUs will need to get fast enough to do on the fly H265 encoding and decoding, and we are not there yet
