Arduino driven 5v and 12v Smartpower

He was updating my personal home “pico data center” in order to get more processing power (swarm cluster) and arrange all my ARM based servers in a cabinet.

He wanted to use only on power supply for all my servers (mostly arm based) instead of multiple 5v power adapters. I also had some 12v needs for my router and my NAS running an Odroid N1 (more to come about it in a future article…)

So He built a custom 1U rackable smart power which provides some remote services through HTTP…

Features

The smart power actually has the following features :

  • 5V 20A capacity
  • 12V 8.5A capacity
  • 6 USB connectors for 5V supply
  • 2 Barrel connectors for 12V supply
  • One temperature sensor
  • Live display of power consumption and temperature
  • Hardware switch to turn on or off any of the 8 power connectors
  • “Cold” power-on sequence for all connectors (eg. turn on servers in the right order)
  • Gather temperature and consumption history through REST API (json)
  • Toggle any connector’s status thought HTTP command
