Individually Addressable Incandescent Lamps

Everyone playing with electronics these days knows about LED strips made of dozens or hundreds of individually addressable RGB LEDs. I love them and make great use of them in the nootropic design Lumazoid music visualizer. But what about incandescent lamps? Old-school...

Frequency Filtering with the Audio Hacker Shield

The Audio Hacker shield for Arduino lets you do some cool things with digital signal processing. This new project shows how a fairly simple Arduino sketch can implement a low-pass filter, high-pass filter and band-pass filter. A low-pass filter allows low frequencies...

Using a Video Experimenter as MIDI Controller

This simple project shows how a video signal captured by a Video Experimenter Shield can be used to send MIDI messages to a synthesizer. A small camera module is connected to the input of the Video Experimenter (the red wire in the picture is for powering the camera...

Digit Shield Used in Concrete 3D Printer

Wow, this is the craziest 3D printing I’ve ever seen. The material is concrete! Andrey has been working very hard for years to developed a 3D printer than can literally print houses. Here is the castle he printed. For more information about this, check out...
