Litecoin mining on "whatever"

I started mining litecoins for fun, so this is really not a post on what the best way would be or how to get rich.

This post is more about what happens if you use "what is lying around", so I installed "minerd" on my raspberry and banana Pi and also looked what phones are still in the desk and installed a mining software from the individual store.

In the last 5 days I managed to get

0.000157304676 LTC

by using some devices, whereas the PIs have been running all time and additional Hardware has been switched on and off sometimes.

  1. Banana pi M1
    ARM Cortex-A7 Dual-core (ARMv7-A) 1 GHz
    Mining average in 24 hrs : 0,8 KH/s
  2. Raspberrys Pi 3 B
    64bit ARMv8 QUAD Core CPU op 1.2GHz
    Mining average in 24 hrs: 1,2 KH/s
  3. Microsoft LUMIA 640

  4. Lenovo A390t
