In the 1960's, I used to go with ham friends from my home in northern Oklahoma to surplus stores in Wichita, Oklahoma City, Kansas City, and once, the epitome, the Collins Radio surplus store in Cedar Rapids, IA. It was sad to see them disappear, one by one. I still fondly remember picking through a huge pile of scrap electronics at a place in Oklahoma City and coming up with a couple of dozen ceramic-metal transmitting tubes. The guy hefted one in his hand to guess how much copper was in it, and sold me the whole lot for scrap copper price (a buck or two - total).
There's a place that sounds much like your Mock Electronics in Orlando, FL , called Skycraft Parts and Surplus (they have a website, google for it). I have been rejoicing finding this place since I moved here -- you can't "just go pick up something", it's just too hard to get out!
That's all right, Max, I'm just happy that we can have conversations like this. I didn't get to see too many editions of Practical Electronics as a young lad,or Practical Wireless for that matter, as my favourite was the Radio Constructor and that's what soaked up my pocket money...
I note that my earlier comment has a 9:38 time tag but it was sent before your 9:33 statement appeared on my screen. Hence the sequence of this thread may appear a bit strange.
Cheers for now.
Well, I am mortified -- I just got an email back from the publisher of Practical Electronics -- he confirms that there was no "Take 20" series there, so you are correct -- I must have been reading it in Practical Wireless (take me outside and spank me now! :-)
I really regret the disappearance of these shops.
Re the long link -- in the future you should go to https://bitly.com/ and use them to shrink the large URL to a smaller, more manageable version -- for example, I just used it to shrink your monster URL to the following http://bit.ly/138rhDo
At one stage there was another magazine called Everyday Electronics - mostly beginners type projects. I think "Take 20" was in there (but could be wrong). EE eventually merged with PE to a new mag called Everyday Practical Electronics (mouthful!) which I think carried over the Take 20 column. Anyway, Max, your contacts there will give us the real story I am sure.
Really? Did they not have this in Practical Electronics also? I'm "gob-smacked" as they say. In fact, I'm just about to send an email to the original publisher of Practical Electronics asking him about this.
I'm not saying you aren't right, you understand -- and I did read Practical Wireless also .. .but I would have sworn this was in Practical Electronics -- watch this space...
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
