The vast majority of what we cover here on the XDA-Developers News Portal relates to software development. Be it new apps, kernel modifications, ROMs, or Xposed Framework modules, we see a lot of cool software tweaks here at XDA. Unfortunately, we don’t quite see so many hardware modifications, probably because many users are unwilling to turn their expensive devices into guinea pig test platforms for potentially hazardous hardware mods. However, not every hardware mod has to be dangerous, and today’s Lego Mindstorm NXT automated charging dock goes on to prove exactly that.

Not everyone likes to leave their cell phone chargers plugged in 24/7. There are various reasons for this, ranging from parasitic/leech power draw to simply not wanting to have things plugged in unnecessarily. While there are devices out there that can automate when certain plugs receive power (and you could always just unplug and plug the wall warts manually), this is XDA and we don’t often like simple solutions. XDA Forum Member macieek1235 created a rather interesting solution using the Lego Mindstorm NXT system to plug and unplug the device charger on command using a series of servo motors. The charger was originally made for the Samsung Galaxy S III Mini, but naturally it can be modified to fit any device with just a little bit of creativity.

If you’ve wanted to create such a charger and/or you just want to see how macieek1235 kept himself busy for a few hours, head over to the Lego Mindstorm NXT Charging Dock thread, take a look at the included charger schematics, and give it a shot.
