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…
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…
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…
