Times have changed, but there’s still something magical about gathering invisible signals from the air and listening to the radio on a homemade receiver. [mircemk] has brought the idea right up to date by building an FM radio with …
You don’t have two ears by accident. [Stoppi] has a great post about this, along with a video you can see below. (The text is in German, but that’s what translation is for.)

Adafruit just put out a tutorial for adding pattern blinking LED lights to headphones. This instructable takes it one step further. This project is really the Adafruit Ampli-tie project morphed …
We’ve seen a great many Arduino synthesizer projects over the years. We love to see a single Arduino bleeping out some monophonic notes. From there, many hackers catch the bug and the sky is truly the limit. [Kevin] is one such hacker who now has an Arduino orchestra capable of playing all seven movements of Gustav …
Boundary Devices is the company who launched the i.MX6 based Nitrogen6 in 2012, a globally adopted i.MX 6 SABRE Lite development board (now BD-SL-i.MX6). The company has recently announced the availability of its new Nitrogen8M SBC (Single Board Computer) that runs Linux or Android on a quad-core i.MX8M processor.

Hello everyone. I am a graphic designer with a restless soul (my site www.inoace.com). I loved doing electronics years ago and than got busy with life and job. I am now blessed with some time ( rare now a days 😛 ). This is my first microcontroller / arduino based project. Edit: Just a tip, I was …
Summary Infrared headphones can be used for listening to music or television cordlessly. The headphones utilize a transmitter that connects with audio cables to the audio source, such as a home entertainment center. The transmitter utilizes light-emitting diodes (LEDs) to direct a focused beam of invisible pulsating light towards a receiver built into the headphone …
