Remote Audio Transmitter with an ESP8266

The motivation for this project was to have a wireless way to listen to my building's intercom remotely, be it from another room or from another state. Having the ability to do this doesn't necessarily add security to my residence like cameras would (maybe keep an eye out for a post on that), but it's interesting nonetheless. So what we can do is capture the audio over WiFi with an ESP8266 and capture it on a server. All with the power of Docker, of course!

Making a Smart Speaker - Part 3

The Orange Pi Zero came in the mail yesterday, so I guess we're ready to move on to the next part in the design of the smart speaker: audio input and output. We won't cover any of the intelligence behind the AI right now because all I want to do is get audio out of the Orange Pi and into the speaker at a reasonable volume, and maybe get voice recognition to work. By the end of this, we should have something that can play music files and maybe transcribe what I say. We'll see.

Making a Ukulele Tuner with Javascript

)I just got a ukulele and I love it. I play it nonstop. Because of the temperature changes in my room and how often I play it, the instrument goes out of tune quite often. I wanted to write a simple tuning program that could play a solid sine wave at the frequencies I needed it to. I found it very easy to tune off of a loud sine wave instead of the sound of a ukulele string being plucked over and over again like most ukulele tuners. This one is going to be very short because this program is very simple and to the point.
