Odds on

[@BaselineNL620]

We once told a trainee that the arrow on a radar cable (between the display and the scanner unit) had to point in the right direction otherwise the image would be turned upside down .... it took quite a while before he realized it. For those who wonder: the arrow does indicate the correct installation direction, but only for convenience of connection. (because the wires through the cable spiral) it is easier to connect in the right orientation (the left one is a bitch)

[@airgunnut9489]

in that case he's better reading than most adults. (come on, how many adults read instructions?)

[@gorillaau]

@@airgunnut9489 there seems to be two types of motorists that car mechanics hate: Those that think the car will blow up if a warning light comes on, and those that will ignore all warning lights on the dash untill they car no longer runs. I suspect both are just as guilty of not reading the user manual.

LMFAO...... AHHH YES and in no time he'll be saying Dad i think this wire is BULLSHIT i think the quality in this wire is BULLSHIT and you know what i think of batterizer.... IT'S BULLSHIT Sagan will be in school they'll do a project on solar power and solar panel roadways and sagan will say MISS, THAT'S BULLSHIT it's not even feasible , the production costs are ridiculous etc the pinciple will put him on detention sagan will be like... THA'TS BULLSHIT SIR, THA'TS COMPLETE AND UTTER BULLSHIT hehe IT HAS FUCKING BEGUN IT'S OFFICIAL Even dave himself can't stop the process now hehe

Sagan is 7 now?! Wow I've been watching your channel for a long time!

[@reallyniceaudio]

wow this never occurred to me till I read your comment, 7 years of amazing content!! education levels are off the hook!

[@mohammedshakir5663]

I feel that I got the Master degree in Electronic Engineering with Dave for free, thank you Dave...

[@neilfraser1235]

I had that exact same kit, as well as the 150 and 50 you showed earlier. This one was my favorite by far. So many good times building circuits projects. Looks like Sagan is enjoying it. Thanks for the trip down memory lane!

[@00Skyfox]

Awesome! I have that exact kit from when my brother and I were kids. I also have the 60-in-1 kit. Some years ago I posted a good quality scan of the 200-in-1 manual to the forum, but I see in the post for this episode, Tandy has posted a link to a bigger version. Hey Dave, I have to say, you're a really good dad. You're patient, you teach rather than scold, and you show a genuine interest in spending time with your kids and helping them learn new things. A lot of other dads could learn a lot from you. In another 20 years, I could see Sagan starting to take over the channel...EEVblog, The Next Generation.

[@jenniferlachance351]

What a sweet boy! He brought many smiles to my face!! Thank you for sharing!

[@AldarisGoldfish777]

I had one of these kits when I was about his age as well! I had been playing with electrical things since I was about 5, but this kit really cemented my love of the hobby. Great moments to have with your young fella.

[@deepmystic5850]

AHH man good to see you with your little one, you are a great role model and I am forever thankful for all the stuff I have learnt from you!

[@TehMG]

I learned electronics as a kid on the EXACT SAME projects kit!!! Very good kit, with an easy to read very detailed manual that progressively teaches you increasingly complex circuits. Lots of fun too and lots of possibilities beyond the 200 circuits in the book. Once I was done them all I started combining circuits, and eventually coming up with my own circuits.

[@CookingWithCows]

it looks like Sagan has made great progress from just holding his fingers up to show how old he is. Great job, nice to see him so interested and outgoing

[@davidcole6236]

Dave, Watching you and Sagan work together and his joy at discovery, it brought a lump to my throat and a tear to my eye. i remembered my first science/electronics kit and working w/ my dad to do the "experiments" . Somewhere between about 1958 and 1961 (I was born at the end of 1954), my dad got a kit for electrical learning; it had a "D" size carbon-zinc cell, wire, light bulbs, nuts and screws (around #6-32 size), some spring brass strips, a fiber tube, a nail, some colored plastic dome lenses for the lamps, and an injection molded plastic "breadboard" to build simple circuits with single and multi-positiion switches , an electromagnet, a solenoid, lamp selectors and other simple demonstrations. A few years later it was a Bakelite "Heathkit" 5-tube AM AC/DC table radio, and from there on I was hooked for life on electronics. Thanks for that video and the warm memories it brought me back to. Cheers, Dave C. Lubbock,TX.,USA

[@spokehedz]

Brought a nostalgia tear to my eye, watching the little dude mess about with the wires... Lots of good memories pulled from the long term storage of me being about that age... Thanks Dave. (who could thumbs down this... Probably some bitter RadioShack investors no doubt.)

[@NuGanjaTron]

Maybe one of the guys who repaired my 200-in-1 after I blew out some of those LEDs. ;^)

[@seancsnm]

You have a smart kid in the making. Some hope yet remains for the future. I got a kit like this as a kid but wasn't able to figure the harder concepts out until college. And it was in college that I discovered that I could have learned them at a much younger age.

[@breakbumper]

I remember a similar kit back in the early 90s. Absolutely heart warming to introduce your kid to this. Nice one!

[@tubelife70]

Holey Blast From The Past!!! That was the first electronics kit I ever destroyed. I think I got mine in 1981... Oh Man, I had forgotten all about this kit. Thanks Dave, now I remember my parents did love me! :))

[@borayurt66]

Brings back memories... 200-in-1 Radio Shack kit was a birthday gift to me. I was already putting together simple circuits on perfboards then but I enjoyed the kit very much!

[@Chris-tx9ou]

I had this very same kit , This brings back so many memories thanks for sharing , All the best from Scotland

[@onecircuit]

My passion for electronics was kick-started when I got my 160-in-1 kit. Still have it to this day. Awesome for those kids in the 80's that couldn't get enough of this stuff.

[@arongooch]

Oh the memories! Awesome stuff Dave. Used to have one in the very early 90's. Something you will never forget.

[@williamcarrington3087]

Compliments on spending time and teaching.

[@mrmobodies4879]

I had a 130 in one kit a long time ago which I damaged from deviating without understanding from the book. Another good learning resource and for children. Please do more videos.

[@scottbaileyExplores]

Like father like son. Nice to be remembered how clever we are as small children. Nice one Dave.

[@Ybalrid]

The kid's genuinely exited by electronics! Dady's doing a good job ;-)

[@ollopa1]

Duuude!!! This was my first kit I bought for $2 at a flea market when I was around 10 years old. I learned everything I could from that wonderful book and eventually dismantled the kit for parts when it had nothing left to teach me. Three years ago when I had my first kid I went on eBay and bought another one in great shape hoping to do exactly what Dave is doing here -- and I'm glad I got mine before this video was made because I'll bet they're all gonna be gone now! These were great kits and obviously had a lot of impact on all of us...

[@4BoltClevo]

I lusted after these kits as a kid. I read the 1977 Tandy catalogue a billion times and just had to know what all the components did so I went and got library books out on the subject. I learnt a lot without actually doing anything practical. Then one day I found $20 under an old mower in the junk pile at the local mower shop. I told the owner and he let me keep the money so I ripped down to Tandy under Sundale Shopping Centre on the Gold Coast and bought $20 worth of transistors, diodes, resistors, capacitors, battery clips, blah blah blah. It's amazing how expensive the components were in the day. I think you'd get 100 times as much these days.

[@EEVblog]

Same, I learnt a lot from just reading and imagining. Didn't have the tools or money to get them in the early days.

[@0RDClark]

Still got mine in the loft. Replaced the LEDs and added a power socket to save on batteries way back when, but apart from that it's as is, and I'm sure it'll still work nearly 40 years later!!!

[@ScottEvans-vk7hse]

Yup I had one of those 200 in 1 kits, way back in the mid 80's many hours spent learning on this kit, my favourite was the AM Broadcaster! 🤪

[@FindLiberty]

APPROVED - Great job Sagan!

[@MultigrainKevinOs]

I had the exact same model and I think my manual is in about the same condition! Got it from a garage sale as a kid. It was the catalyst for me becoming an electrical engineer! Those were all such wonderful little kits and accessible introductions to electronics, glad to see Sagan excited to play with it.

[@AdammP]

Lovely video Dave, good to see you fathering skills are going to good use. We need more figures like you in this world.

[@emmanueldekerchove9691]

Can’t believe that Sagan is already 7! I now realise I’ve been following the eevblog for a long time now:-). I also started around 7 with the 50, 75 and 150-in-ones then switched to the Phillips EE 2000 series all the way up to the EE2007 (scope..) as they were quite popular in Europe at the time. All kits still laying around and working (hopefully). Add a few years of tearing down everything and messing around with uv lamps, perchloride and shortwave radio and aiming for EE studies at 18 had become a no-brainer. Looks like Sagan is on his dad’s trail !

[@damien0505]

Wow memories! I had one of these (still have somewhere) as well as a 100 in 1 and a 20 in 1. Was a great way to learn. When I ran out of components I'd use two or three of the kits together. Was a great foundation in electronics. Thanks, Dave and Sagan.

Great video! Brought back lots of memories of childhood. Had the 150 and 200-in one kits at various points. I remember making a wrong connection and blowing out one of the transistors and actually troubleshooting it by checking the junctions with an even more primitive Radio Shack VOM than the one Dave used. Had to go to RS and part with $1.39 or whatever for a new 2N2222 off the pegboard. Good times.

[@EEVblog]

Did it come in blister pack like Tandy?

[@bobweiss8682]

Oh yes. Blue pegboard card and an "Archer" part number...

[@alexmihai22]

Love it! When I was 8 I was already interested in electronics after I saw on TV how a kid constructed a radio with a large variable capacitor, a diode and few components, and I wanted to build one too, it seem amazing to me! 2 years later a guy came and started an electronic club at school, and there I learn a lot about components and I did some practice. Since then I've got in love with electronics.

I didn't know that it existed. On the photos on internet it's clearly some years older than the EE2000 series.

[@DanOConnorTech]

Excellent stuff, Dave. The notes on page 7 of the instructions about keeping a notebook reminded me of Pirsig's "Zen and the Art of Motorcycle Maintenance" where he talks about using Scientific Method in problem-solving and the importance of keeping a notebook. It's good to teach them proper methods at a young age!

[@AdamEbelgccengineering]

I had one of these kits for the first time in the year 1990, a replacement in 1996, and also another one around 2009. They are very easy to find and use. You should build the One Transistor Radio circuit, AM Broadcaster Circuit, and Crystal Set Radio circuit if you're into radio communications.

I scrapped mine long ago for the components. kind of a dumb decision in hindsight, but it wasn't a terribly large one.

[@EgonSorensen]

Got one of those kits quite a long time ago for Christmas, and I still have it - in great/mint condition too :-) I also got the Gakken EX-150 system when I was about Sagans age, and boy those denshi blocks with multiple components inside made it nearly impossible to build something on your own. Thanks - It is a great introduction to electronics, and hours of play and learning! en.wikipedia.org/wiki/Gakken_EX-System

[@LarixusSnydes]

I still own one, but the lamp is gone and hard to replace nowadays. Previously I owned a 150 in one kit, but that one had broken battery connections and the paper was eaten away by $%! bugs.

I had one of those when I was a kid (early 90's), it was the Science Fair 130-in-One. I had to google and find it because you put me in nostalgia crisis and funny enough, I found the picture of it on your own forum =D

[@jbmcb]

I collected those electronics labs obsessively when I was young. I think I have a dozen or so. I never had the 200-in-one, lucky kid! Those and the Forrest Mimms getting started in electronics handbooks taught me a lot.

[@MrAdzielinski]

I was so lucky my dad still had all of his from being a kid and let me use them. He had the couple different old 10in 1 radios the wood 50in 1 you showed , a wood 160in1 and the highlight 200in 1 . At the time radio shack was still open he bought me the modern 130in1 too. I didn’t realize as a kid other kids didn’t know how to build electrical circuits.

I had a kit very like that when I was about Sagan's age (more than 40 years ago) and I loved it. I think it is still in my folks' house. I need to dig it out.

[@crittersweb]

Wow! I also had both those kits when I was a kid. I got the 50 in 1 from a flea market when I was about 7-8 years old and then the 200 in 1 for my 11th birthday. I was so happy, it was the only thing I wanted I got it. I spent so much time with that thing. I can't remember whether it was the 75 or the 150 in 1, wood case, I got in between. Some of my better childhood memories. How cool.

[@ronjon7942]

Hey, I had this kit growing up, I’ve no idea what happened to it. Until your video, I forgot exactly what kit it was; now that I’ve seen yours and Sagan’s work here, I can now go hunt for a new one!

[@gutsngorrrr]

That's the electronics kit I had and I wish I still had mine. My parents got it for me because they were sick and tired of me pulling apart all my electronic toys to see how they worked and make new things. Was an amazing kit and I hope sagan enjoys it as much as I did.

[@profblindserv]

I had those as a kid as well. I loved them.

[@TurboBaldur]

I got the same thing from Tandy when I was a kid, although the front panel on mine looked different the board layout, components and projects were all the same. I still have it somewhere but one of the NPN transistors blew out and I have not been able to source a good enough replacement. I must have spent thousands of hours playing with it, doing every project and then some. Later when I started designing my own circuits I would often use this kit to test out my ideas. The transistor blew when I accidentally bypassed a current limiting resistor when making a change to an audio low pass filter I was testing out.

[@darikdatta]

I wish I still had my 150 in 1. I spent HOURS with that kit.

[@NuGanjaTron]

Wow, that brings back memories. I just came back from the basement and checked on my 200-in-1, and I'm proud to say it's still with me after all these years, and in pretty complete and good condition too -- unlike myself. :^\ I even still found the original receipt dated May '82, bought from Tandy in Melbourne for (then) whopping $55. And good on ya for getting your son involved; I wish my parents had fostered my interest in electronics and computers back then. Alas, they didn't care, had no interest in the looming digital revolution, and even actively discouraged me. So I invested in my future out of my own pockets. Sagan is one lucky kid, and I wish him a bright future! :^)

You had IC's in your kit? I'm a bit older, and my 150-in-1 just had transistors. But after I built every project, twice, annoying my parents with scratchy noises and beeps, then came the next phase... my mom worked in building that had a Radio Shack. I would give her lists of things to buy-- components, enclosures, and eventually blank PC boards and bottles of ferric chloride. I made so many mistakes, but that's how you learn. Now I'm 53 year-old software engineer, but I still remember the endless fun of my 150-in-1.

[@bobweiss8682]

I had both the 150 and the 200 kits, and IIRC they BOTH had ICs. The 150 in 1 kit had some kind of analog audio amp in a SIP package. The 200-in-1 had a 7400 and a 7476.

[@ScubaAnt72]

Wow that brings back memories (I was probably Sagan's age when I got my Science Fair)! I'll have to dig through the shed and find my old one and get the kids in to it. I recall blowing the LEDs at the time, now I'm an engineer I can replace them :)
