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...
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...
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...
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...
I am so excited that the nootropic design Defusable Clock was used as a prop in an episode of the new TV show The Tomorrow People on the CW Network! The episode “Kill or Be Killed” aired on October 30th, 2013. If you watch the episode online the Defusable...
A while back, I did a project using a 32×16 RGB LED matrix panel from Adafruit but found that connecting an Arduino to the panel was a real wiring mess. So I decided to design a small Arduino “backpack” board that snaps right onto the back of the...
