ed-thelen.org is one of the most fascinating sites on the web to me, look around, its gigabytes and gigabytes of old missile tech.

If we lived in a peaceful world, building miniature missile systems to shoot down clay targets would be a hell of a hobby, but unfortunately, that seems like a bad idea given the ... world.

> Analog computers may seem to be "simple" or "like a toy computer", in fact they are powerful tools that were used during the 1950s and 1960s to design and test systems like ICBMs, supersonic aircraft and spacecraft. this is indeed a very interesting quote that we -dealing with digital- often tend to forget.

As someone who builds essentially analog computers (modular synthesizers) this is just as viable a form of computation as anything else. Of course you have common analog pitfalls, like noise, drift, temperature stability, etc. but the results are nearly instant. And of course there is something magical about putting some analog voltages in and getting the result out as yet another analog voltage.

Not directly related, but brings to mind the training video for the fire control mechanical computers on US Navy ships: https://www.youtube.com/watch?v=s1i-dnAH9Y4

Also not directly related:

David A. Mindell, "Between Human and Machine: Feedback, Control, and Computing before Cybernetics" https://press.jhu.edu/books/title/1207/between-human-and-mac...

Absolutely epic book.

Very interesting to see this here. I bought the Nike missile control unit years ago from some guy here in the Netherlands and it still sits in my garage. It has cool mechanical gyroscopes and microwave components. I disassembled most of the electronics modules and made a guitar amplifier from some of the pencil tubes. Sounds great and it's kind of cool I think, making a musical instrument out of a weapon.

It feels a bit strange when you hear naval people from the 40s talking about 'computing a firing solution'. But these systems must have been reasonably sophisticated for 2 moving warships 10+ miles apart to stand any chance of hitting each other, allowing for wind, changes in atmospheric pressure, the earth's curvature, pitching and yawing and coriolis force.

There are plenty of model rocketry competitions. For example to take an egg to a specific height and land it again by parachute in a specific time (unbroken). My son competed in the UKROC competition with friends: https://www.ukroc.com/

Building a rocket with guidance would be pretty cool. But would probably get you on a government watch list!

So the short story is that the missiles were essentially radio controlled drones, radar measured the location of the target and the missile and from the ground the analog computer flies them together (or close enough that the bang will bring it down)

And the bang could be nuclear[1], so it didn't have to get that close.

[1] What could possibly go wrong?
