Ethernet (LAN RJ45) cable tester circuit

In this article you can find instruction on how to make a simple ethernet cable tester driven by an Arduino. I was inspired by this page that simply and clearly describes how to make a tester for e…

I was walking through the hardware store the other day and I walked past an energy meter which clips onto your home’s electricity mains and then provides you.

Believe it or not, an ammo box can still be of use to you once its rounds are gone. You can use it for storage, as a toolbox, or possibly even as a Faraday cage. But if you want to use it as more than just a container, why not turn it into a portable set of speakers that you can take with you anywhere? The ammo can speaker pictured above was made by Instructables user Dustin White. He started with an empty .50 cal box, though you could probably even use thinner 5.56 or 7.62 mm cans. He…
