The Internet of Things (IoT) and Bitcoin (Bitcoin) are all fun new things today, so what's the point of putting them together? In short, it is the use of Bitcoin networks for secure, autonomous trading of transactions involving computing resources, storage resources, bandwidth, data, and even public displays that can help other devices display content. The middle will involve sensors, IoT short-range communication protocols, cryptographic currencies and block chains, MapReduce and Hadoop, machin

capable of a short range transmission. Here, I can see a test broadcast from several feet away even without attaching an antenna.Still able to receive from a few feet away even without an antenna. Image by Sadmin/null ByteYou should use the GPIO pin to test your messages whenever possible to avoid interfering with other frequencies Unnecessar ily. While good for testing, the pin alone cannot overpower a station. Once you ' ve confirmed your ' re transmitting, let's try hijacking a signal.Step 4

If the device is not received, after using VNC login, the display resolution is very small, should be 480p, resulting in a very inconvenient use.By modifying the/boot/config.txt file, the desktop can also be displayed at a set resolution when the monitor is not connected. Here's how:1. Open Config.txt FileMethod One: Use the SD card reader to open the Config.txt file in the boot folder in the Windows environmentMethod Two: After entering the raspberry
