Some realizations that I had after being in the “normal” world after growing up in an engineer’s house: 1. Electromagnets aren’t generally toys. Still my favorite one, though. 2. A custom built closed circuit cable TV system that pulled OTA TV from one of several antennas and included a single…

There was no subreddit for the PDP-1 so I made one.

The days of hope and grace seem like they’re gone for the time being. I just hope that they come back.
