I graduated high school in 1970 and still have my slide rule. I wish my eyesight was as good as it was then. I used it a bit at the beginning of college, just as calculators were becoming available. My best friend's dad worked for Wang Laboratories and had some of the first desktop nixie tube calculator models. He let me come over and use them for my homework assignments. My mom remarried in 1994 to Byron F. Deming. He worked for Rocketdyne and was part of the early space program. He had wonderful stories about Werner von Braun, Kelly Johnson, and others. When he passed away and his daughters were going through his things, they offered me his slide rule. I always wonder if some important orbital calculations were performed with it. It's one of my most cherished possessions.
That was terrific. My introduction to slide rules was watching a GA Tech student who was wearing the longest one I ever saw, jump in his car and slam the door on it. It was bamboo and smashed. He sat on the tarmac and cried. My first one was a picket I bought for HS chemistry. It forced me to get a grip on scientific notation. Yes, you did have to get a good grip on the decimal. After college, I started attempting to design circuits and discovered the HP RPN calculator. Life was good. And I have noticed a lot of 2 pi calls in EE formulas. I think it was Oliver Heaviside, the Brit who boiled Maxwell's 24 equations down to 4, who wrote a paper denouncing this and explaining why it shouldn't be there. That's a great slide rule. It would have helped with the resonance problem(s) on the extra class exam. Thanks for this video. I'm going to hunt up my 6" picket!
When I was in the Navy, and attending Advanced Electronics Class "B" School on Treasure Island back in 1968, we used Pickett and Dietzgen slides rules. I also took the CIE Electronics Correspondence Course back in the early 70s, but then I was picked up for the Navy's Associate Degree Completion Program and didn't have the time to finish the course. It was a good course, and I got about 2/3 the way through it. I didn't take the slide rule course though as I was already proficient in using a slide rule.
I used one a Lot in HS and College... I Still Love slide Rule to this day... no batteries needed, i also Studied electronics in the 1970s with The International Correspondence schools while still in high school. I think ICS is now CIE... i love that school very much !!!!
International Corrrespondence School is now Penn Foster Career School. I also completed the Electronics Technician course with Penn Foster just recently. It's a very thorough and challenging course, as I'm sure yours was as well.
I bought mine on Ebay, absolutely love it! Like you, I bought it as a collector's item, but I found it so handy that I brought it to work with me. Now people ask me to solve reactance and resonance problems just to watch me use it. They're always amazed that I can solve it faster than they can. :D I defaced mine a bit with a sharpie. I added indices for kOhms on the reactance finder and penned in nF next to mH. You have to be careful with that Cr scale because you may need to point at 12 in your example or 1.2. Check them both to see which one is close to 5 kHz.
Just picked up one of these slide rules at a local ham fest. Used the MB-4/E6B circular slide rule in the Air Force. Slide rules were slightly before my time. Downloaded the instruction books and will work thru them. I also have a HP-32 do not use calculators with equal buttons. Very good video.
I took classes from CIE and I still have my slide rule. I have to admit I haven't used it for years, but this video makes me think I should get it out.
I took that home study course for kicks while I was in High School. I was surprised how professionally it was done and helpful they were. I had a slide rule but don't recall if it was included in the price. Don't recall being that fancy and having a case. I went on to college and an EE for 40 years. Good times.
I also grew up just at the very end of the slide rule era. I remember doing things on a slide rule in high school but then got a calculator so out went the slide rule! Too bad I ditched them all because they are very useful and can be accurate enough for most normal work.
I had one of these, acquired by way of my high-school chemistry class. The back of the slide rule had a periodic table, and there was an insert card with all the fundamental constants and other reference information. It was the only thing we could use on chemistry exams, no calculators. (This was around 1976 or so.) I went looking for it one day, couldn't find it, and bought one from someone on eBay. And then of course I find the one that was missing, so now I have a spare 🙂 Very nice slide rule; you never went off the end, it just wrapped around.
I have a selection of Picket slide rules from the mid-70s... The plastic student model, an aluminum EE model (for electronics class) and a circular aluminum rule just for the novelty of it. We weren't allowed at that time to use calculators.
I aways heard of those ruler calculators but never saw one or learned to use it, thank you for sharing this knowledge, it seens to be faster to use it than type on a eletronic calculator
Hi. I just found my cie slide rule. Got it while doing 1st class fcc course. Yes 4 booklets came with it. Never did learn how to use it. Got mine in 74. It came free with the course as a bonus. It's been packed away since then.
Wow. An awesome slide rule with so many features. When I think of slide rules I understand why they use log scales such as dB. It's so you can add instead of multiplying. And also you can get several decades in a short space.
I have the exact same one! I brought it to my general exam as a joke, since they obviously wouldn't let you use it with the cheat sheet on the back. I used a K+E DECI-LoN when I was in high school out of sheer perversity (I graduated in '07).
I never knew of (let alone attended) CIE, but I have one of these slide rules. I just picked it up off of eBay. I have the same model as yours. And thanks for the links to the instructions. :)
The image of the engineer on the CTI manual has him sitting in front of a representation of a Heathkit SG-8 signal generator and an IO-10 oscilloscope. The meter on the right was supposed to represent a Bird 43 perhaps?
Lol... I got one from them when I took 2 courses, industrial electronics & Ro optics then enrolled in their Bachelor's degree program Electronics engineering, later specialized in Bioengineering. CIE wad actually pretty good, if you wanted to learn you'd get a good education thete, it wasnt easy.. they really stressed maths & calculus at that time anyway & the GI bill would even pay your way 🤔

It is called a cursor. Interesting stuff. When there's an EMP you can still calculate stuff with this!!

Used my in tech school, 1967 1970

Amassing my own slide rule collection. I got one of these on Ebay too, and printed all the manuals. Yes I enjoyed your video! Thanks, that was fun.

I had a plastic circular slide rule in my pocket in high school. Fast and reasonable length in a small package.
I had one of these, acquired by way of my high-school chemistry class.

I still have some slide rules stored somewhere
Plastic and original Hemmy Bamboo made in Japan.
you´re video made be buy one of these slide rules. A great tool. Thanks.

I used a K+E DECI-LoN when I was in high school out of sheer perversity (I graduated in '07).
i attended, and was taking classes when they went under. it was an experience, lets say.
I never knew of (let alone attended) CIE, but I have one of these slide rules. I just picked it up off of eBay. I have the same model as yours. And thanks for the links to the instructions. :)
I used Capitol Radio Engineering Institute. They gave a K&E 68-1100 Deci-lon.

probably a VTVM
@@IMSAIGuy probably.
Batteries not included, no assembly required!
Amazing! Batteries not required!
I have. I had a bad experience. Would NOT recommend it. I actually got their name off a slide rule I bought for Ham radio.
Don't tell anybody...I wore my slide rule on my belt...but don't tell anyone!
as long as you didn't have checkered pants!
@@IMSAIGuy No, but I thought about buying Curious Marc's checkered pajamas! ;-)

I just looked CIE up. Sadly, Wikipedia says they closed permanently in 2022. en.wikipedia.org/wiki/Cleveland_Institute_of_Electronics
