ESP32 WiFi Range Testing - 10km using Directional Antenna
How to send arbitrary data by exploiting a function in ESP32's WiFi Stack: github.com/Jeija/esp32free80211
Consumer grade WiFi hardware being able to decode down to "femtowatts" of signal strength might be a bit exaggerated, but e.g. the USB WiFi adaptor in this video has a receiver sensitivity of -99dBm @1Mbps which is approx. 100fW. If we count the directional antenna as part of the receiver and add the antenna gain to that figure (this part of the calculation is somewhat disputable), we get the less-than-femtowatts mentioned in the video.
English subtitles for this videos are available, translations are always welcome!
The camera recording code is based on igrr's esp32-cam-demo: github.com/igrr/esp32-cam-demo
More speifically, I'm making use of the modified version by Oitzu with OV2640 JPEG support: github.com/Oitzu/esp32-cam-demo/commits/ov2640-jpeg-playground
The animations in this video were created using 3blue1brown's amazing manim software (github.com/3b1b/manim). Check out some of his mathematical videos on his channel: ua-cam.com/users/3blue1brown

How to make the Minecraft world look spherical

On a side note, the log-polar coordinate system (en.wikipedia.org/wiki/Log-polar_coordinates) also uses this kind of transformation. It has various applications, e.g. in image processing where the density of squares in the grid correlates with the density of light receptors on the retina.

    Why not just fake a round world? There needs to be a seemless portal plugin for minecraft, where your world is limited in size and has to be quadratic. The seemless portals need to be on every 4 sides and the seed needs has to create a seemless transition on those 4 sides. Now get a shader that morphes the horizon and now you got the illusion of a round world. If you get to one corner of the world, you will be able to see 4 portals at the same time. The hard part will to program those portals. For example, it needs to be possible to render chunks that arent really on your screen. You literally see those chunks through a camera that moves opposite to your movement. Also the portal needs to render chunks that are actually behind you.

    I just remove the antenna from the grid reflectors and mount the esp32 or esp8266 itself in a PVC tube in its place. It's still using the standard PCB antenna, but it's now in a nice high-gain place! So, "technically", I'm not really breaking the rules, but get a few kilometres range on my mesh networks. 🙂

    3:20 Here is the thing tho... The MC world is 7 times that of Earth, it's huge. Not only that, you don't really need to be able to dig very deep or build extremely tall. If we don't modify the max height and depth of MC too much, there would be no distortion problems anywhere in 99% of places 99% of the time... Right?
