I really apologize for not posting anything for a veritable forever on my site here. I am trying to catch up.
I bought a Radiator with my Covid stimulus check because it looks like a perfect addition to my addiction to drawing things on an oscilloscope.
The device was designed and built by four titans of electronic circuitry and you can read about it here.
I also bought a little HDMI recorder to save the patterns directly to an SD card, because I don’t have an ILDA laser. I record the audio of the X and Y audio signals because I love the sound.
