The "Pocket Crypto Miner” has everything needed to mine small amounts of crypto and fits in a pocket/purse-sized Altoids tin and mines cryptocurrencies using free "green" solar power whenever and wherever the sun shines. More importantly, it is a great hands-on and participative way to experiment and learn about mining and the role of miners in the cryptocurrency and blockchain ecosystems. Learning is best done by doing. And some crypto is better than no crypto. It is also worth mentioning that some cryptocurrencies are designed and optimized for mining on low power microcontroller rigs. The Pocket Miner is fully programmable for a wide range of cryptocurrencies, with some cryptographic algorithms (such as SHA256) in hardware.
