My friends! Thanks for interesting in this topic! I am sorry I explained the project without the rest: I want to use solar panels in a sunny, windy and hot place. I live in a island and there is a lot of wind and sun! We use four big Diesel Engines to product electricity. It is mutch more nonsense to use megawatts for frac/Bcoins rather than low voltage, but free, for Monero or Zcash. I automated my OrangePi that it boot after the sun rises! The ARMBIAN should lounches the miner after boot. It boots with 5volts! I would like to mine some Altcoins ASIC resistant. But the only miner seems to be BFCminer. Please could anyone spend few minutes to tell me where I can find a miner for ARM processors? Many thanks and greetings from Italy!
