In recognition of Father's Day, I thought I'd give a shoutout to possibly the Father of DIY Laser Building, C. Harry Knowles of Metrologic. Check out his biography "Genius in America" by Mary Ellen Hendrix for more info. His article in the December 1969 Popular Electronics (seen below with one of his early tubes) really started the hobby. A great example is seen below featuring a start button, excellent craftsmanship, and purple paint that screams the early '70s. And from a technical conference from around the same time, a pointer built by John Hall.
