Interview: Ask Forrest Mims About Rockets, Electronics, and Engineering

With his popular Getting Started in Electronics, and Engineer's Mini-Notebook series and a number of different electronics kits sold at Radio Shack, Forrest Mims inspired countless scientists and engineers. Even though he received no formal academic training in science, Forrest has appeared in 70 magazines and scientific journals. He has worked as a consultant for the National Geographic Society, the National Science Teachers Association, and NASA’s Goddard Space Flight Center. Today, Mims works on many scientific projects including climate change research. He's agreed to answer all your questions about science and engineering. As usual, ask as many as you'd like, but please, one question per post.

    You are the quintessential tinkerer with a non-standard education. What was the key inspiration that started you on this path?

  3. Past vs present by ArcadeMan · · Score: 3

    What's your opinion on the old ways, i.e. buying parts locally from Radio Shack and meeting people in local clubs compared to the new online way of buying parts and kits, publishing tutorials and forums full of people helping each other?

    More to the point, what do you think has been lost from the old way and what has been gained from the new way?

      Having a local real electronics store available is nice even when bulk parts are cheaper online. There's always that one random thingamajig that you left off the bulk purchase, that you discover on the evening you're soldering everything together; and you don't want to pay $5 shipping for a 10 cent part and wait a week to finish the project. Being able to pick up a 10 cent part for $1 at a local store is really handy. Unfortunately, RadioShack hasn't been that store for a couple decades.

      Ah, of course, so you make foxhole radios from locally-sourced blue steel and galena crystals you mine from your own garden? Perhaps you build your own carbon-arc transmitters or make your own vacuum tubes? The problem with "doing things the hard way" is there's almost no end to how hard you can make it. So are you more interested in the destination or the journey? If it's the journey, read this:

      Of course you can still buy Varicaps. When did you check?

      Maybe it's time to re-think your approach??

    Of all the projects you have worked on, what has been your favorite? Personal or professional. (I would like to express my gratitude, getting started with electronics, got me started in electronics and I am now an engineer. I also have a "non-standard" education as they say, having mostly taught myself from reading and taking online free courses.

    Second that. I was introduced to Forrest's work back in the TRS-80 days, but his quintessential work for me was the Radio Shack publication, "Getting Started in Electronics." Handwritten on graph paper and printed on 8.5" by 11" newsprint with a soft cover, this was the ultimate intro guide for anyone who had any interest in electronics. Many years ago, I worked at Radio Shack as a summer and holiday job, and every time my manager was away, I'd sneak away the a copy and read it (along with some ham radio books as well). One time a customer came in asking about a fake car alarm box, and I grabbed out the book and we used that to build one. He bought dozens of parts that day (oddly enough, I got in trouble with my manager for that, despite really cleaning house). An original copy of that book still sits prominently on my shelf--one of the biggest influences in my life. So, yes, thank you very much Mr. Mims!

    Mims, why do you trust science when it comes to electronics, but not when it comes to biology?

    What do you feel about the Maker movement and Makerspaces in general?

    It seems to me as the Maker/tinkerer is the new equivalent to the electronics hobbyist. Do you believe new project designs need to keep this in mind? (i.e, present the design of an entire gadget instead of just the electronics)?

    the theory was that electrons travelled through conductors at almost the speed of light

    I don't know when did you learn that, but no physicist worth their salt would say that by mid 1930s at the latest, I'd hope.
