Ok, I have not been diligent in producing some software. Most of the algorithms that I have seen to do this job are rather slow. I have defined a MAX_LETTERS as a constant of 10 which will give me generous room for my ID Code. Since I like to modular…
Hi, these are terrible days, in Italy we have been locked in the house for days to avoid the spread of Coronavirus.
What's better than designing and building something with Arduino? I thought of creating a small circuit that, based on the values of…

BUILD(I): The Annoying 'CAPS' Lock Buzzer
The CAPS LOCK key is the most annoying key on the keyboard. Majority of the times, you have noticed…
This is an Adafruit Neotrellis M4 synth board. It can run Arduino and Circuit Python. I run some audio samples with the following code on it:
import time
import board
import busio
import audioio
import adafruit_fancyled.adafruit_fancyled as fancy…
I'll be the first to admit ... perhaps this music from a power supply thing has gotten a little out-of-hand. First, I played a poor rendition of the Mario theme . It was a proof-of-concept, not really intended to go anywhere but perhaps to bring a smile…
Since I posted my first version of making music with a power supply , it seems there has been some interest in the topic. Unfortunately, not all of it necessarily that positive. I understand ... art is a little bit like that ... sometimes it's hard to…

My holiday may be looming, but actually, after seeing the relatively positive response to my last quick project which looked at abusing a Rohde & Schwarz RTM3004’s arbitrary waveform generation features to produce audio , I thought it might be a good…
The 1DUltraBot is now finished, apart from the final 3D printed flat top piece. The circuit diagram is illustrated below and is very simple. One digital output (D2) from the Nano to control the servo motor and two (D6 and D7) to control the ultrasonic…
Even though I’m about to leave on a month-long holiday, I decided to spend a little time to put together a short project for element14’s Project 14 Acoustics Challenge. I was inspired by a Christmas video where someone used an oscilloscope’s arbitrary…
After moving and lighting stuff for months, I moved to some, hopefully nice, acoustic/audio project. In this context, the project I am presenting, as well as the next projects I have in mind, are more acoustic projects than pure audio builds.
This…

I first saw this discussion and it turned out sound was a good choice to transmit data one way> How to transmit data underwater over 40m So, I wanted to make a little project that demonstrates that possibility.

This is the final post in a three part series on how to create an audio amplifier using the classic TI LM386 which has been further adorned with PCB art. The method for transferring art work to a PCB was described in the first post. The LM386 amplifier…

Hard of hearing people face all sorts of problems beyond the basic problems of communicating. One of these problems, which is potentially fatal, is not hearing sounds like someone blowing a horn as warning. I’m partially deaf in one ear…
