Everything for Electronics


Want to be sure you’re playing musical chords correctly? This unit will tell you if you are and display a light show in the process. I stumbled upon this circuit while trying to design a custom frequency tuner for my guitar and is hands down the best sound to light device you could ever build.


Build the LED Matrix Game Player

Those 8 x 8 matrix displays are good for more than just making scrolling signs. With a little imagination and a whole lot of extra time on your hands, you can actually use them to create simple yet amazing little action games. If the game is interesting enough, at some point you stop noticing that it is taking place on a field of only 64 LEDS. The only thing that matters is victory.
