Intro: The WORLD FASTEST and Cheapeast NodeMCU Housing
Here is the world fastest NodeMCU Housing!
You need a NodeMCU :) and a Tube from a fizzy tablet. (I have always Magnesium in my castle)
A drill or hand drill, may be a cutter to make it "looking good".
My Tube have a diameter from 2,7 centimeter.
First cut the tube to the right length, i cut my first to 5.2 centimeter.
If you want that the cap can close the tube, make the tube in my case: 6,7 centimeter then.
Then make a hole in the bottom, you can hold the NodeMCU from outside and make some wild signs to find a
good place to drill the hole. With a cutter you can make the swarfs going away.
Easy isn't it? :)
