Summary

are you bilding LEGO Mindstorms robots? are your batteries always empty? don't have a battery at hand?
build your own PMB (poor man's battery) ... print out this fake battery to power up your Mindstorms RCX, NXT or EV3 from a power supply!

Instructions

STL files tested on a Dimension 768 BST printer with support material ... OK!
STL files tested on a Ultimaker printer without support material ... OK!

  • print out all 4 parts ...
  • organize M3 and M5 allen screws and nuts ...
  • organize LED and resistor for 9V, some wire and a jack ...
  • I would suggest a 9V DC power supply with at least 2000mA current ...
  • solder ... play ... have fun!

WARNING:
Do not try to build this adapter if you don't know what you are doing!
I shall not be held responsible if you burn your RCX, NXT or EV3 with incorrect voltage or bad polarity!
