3D Silhouette Light Box



In this project, I am going to show you how turn a photograph into a 3D silhouette light box. This is done by separating the picture into different layers based on how far away the objects are in the scene. Each layer is then turned into a silhouette cutout. The layers are reassembled with spacers in between each one. This gives the image the appearance of depth and creates a 3D effect. You can also add lights behind the cutouts to make your images glow and create shadows between the layers.

DIY Simon Memory Game


Electronics memory games like Simon can be a lot of fun. But it is even more fun if you add a second player and make it a competition. So I designed a two player version of the game that runs on Arduino. This lets you play Simon head to head.

To make it even more interesting, I added jacks that allow you to use external switches. This lets you use almost anything as a switch to play the sequence. All it has to do is connect the signal wire to ground. You can use large push button switches. You can hook up piezo vibration sensors to a drum set and play Simon with a drum set. You could even wire it up to the switches on a "Guitar Hero" style guitar. The choice is up to you.

Frozen Pipe Alarm



Winter is coming. So it is time to make preparations. If you live in a colder climate, you need to be concerned about the possibility of your pipes freezing. There are a lot of preventative measures that you can take such as insulating your pipes and leaving the water dripping. But for a little extra peace of mind, I designed a simple alarm that will notify me if the pipes are getting too cold and are in danger of freezing.

Color Recognition Lock Box



There are a lot of ways that you can activate an electronic lock. You can use passwords, radio signals, or even voice commands. In this project, I am going to show you how to make a lock box that opens and closes based on color recognition.

With a color recognition lock, anything can be a key. You can set the lock to recognize the color of a cereal box, or the cover of your favorite book. You could even use pictures on your phone as the key. With so many different color combinations, a color lock is also very difficult to break into.
