Amateur Digital Electronics with the MightyPEZ
My journey in amateur digital electronics. The focus is broad, from retro computers to electron circuits. I produce videos on topics that I am currently working on in my "Rat Lab", and find sharing information helps focus my personal learning. I am not an EE (probably didn't need to state the obvious). I enjoy learning through failure (I fail a lot, so I must be getting smarter).
My first computer was an Atari 400 (which I still own)
