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

Recently on the Raspberry Pi 2 toss video, used to do FPV, but found that the 2.4G control will seriously interfere with 2.4G WIFI, in the open control when my desktop + external USB card is frequently dropped. Consider a bit, although the 5.8G frequency band is lower than the 2.4G penetration, but at this stage 5.8G is cleaner, and 5.8G and 2.4G do not have a frequency-doubling relationship, it is not easy
