I'm thinking more to do with the development and spread of ideas, rather than particular technologies (eg, computers or weapons).
I'm reading Matt Ridley's The Rational Optimist and the first few chapters have provided an interesting overview of the history of innovation over the past 100,000 years or so. I want to find out more about how ideas in technology and innovation developed and spread.
These are a little obvious, but if you haven't read them, you're definitely missing out:
A Short History of Nearly Everything by Bill Bryson
Not really original, but great fun, great stories and exactly what you seem to be looking for.
Thomas Hughes, American Genesis.
Steve Usselman, Regulating Railroad Innovation.
Lou Galambos, Networks of Innovation.
There are hundreds of other very good title out there, but these three are, IMO, foundational to your question. Start with Galambos, then Hughes. If you're really into it, go for the dry-ish but hugely informative Usselman.
Is this sort of stuff is of serious interest to you, look into the Society for the History of Technology. Their journal, Technology and Culture, is fantastic.
The Discoverers by Daniel Boorstin is a really great history of science read. It manages to be very thought provoking without being too dense- can't recommend it enough.
