I still have a small hand wire wrap tool & used it 3 weeks a go, I also use a modiffied ball point pen cartridge as a"mini" wrap tool. Steve Ciarcia wrote an article about it in an early BYTE, and I was bite.
I still find wire-wrap useful on occasion. You can get a lot of excellent demo/dev boards with 0.1" pin pitch (or Euro versions with 2,54 mm pitch :-), pop them onto a perf board, and wire-wrap them together. It's a lot easier IMO than point-to-point soldering, and you can easily modify the connections and reuse the parts. I used wireless breadboards when I was a kid, but I find it too easy to tear wires out accidentally. Plus they don't have enough contact points -- it's not like the 24-28 gas-tight connections you get with wire-wrap.
Tom - The article really isn't about marketing - that's just my day job. Although, I happen to consider a solid technical background and understanding of what customers do to be vital parts of marketing. I just run across a lot of different components, boards and levels of complexity. I see a lot of what's done right and a lot of what's done wrong. Hopefully now and then I can save a few people some time, frustration and money by passing some of this knowledge along.
I'm still not sure what this has to do with marketing, but I enjoyed the ideas presented on building prototypes. More on that, please. It took me right back to my days soldering transitors into my Heathkit FM tuner (which I still have somewhere.)
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
