Once again, here we are with another tutorial to “Awaken the Force” within you! With the new Star Wars movie just around the corner, we thought it would be fun to use the force to control PHIRO. In this tutorial, we will be using PHIRO Pro with Arduino along with some awesome Flex sensors. “To the tutorial go, we shall. Yes, hmmm!” […]
For a long time I’ve had old back up cell phones taking up space in my desk drawer. I was curious if I could put any of these old phones to some use. I can’t just throw them away so I decided to try and re-purpose one of them as a portable charger for my
