Tandy Science Fair 150 in 1 Electronic Project Kit

[@videodistro]

My dad designed and wrote the 150-in-One project for Tandy. I developed the black and white photos that he took with his Canon camera out in the sun (um, that may have been for his books). My brother drafted the schematics. It was a family event! :) Glad to see so many young people enjoyed it so much! My dad was always a teacher.

That sounds amazing!

Wow thats cool. My Dad had a TV repair business and I was around 10 years old when I got this kit. I built the fish caller oscillator and took a small speaker from a doner radio. I sealed the external speaker in a planters peanut can. It worked! I used to put the speaker against the side of our fish tank and the fish would come to that side to investigate the sound. I later dropoed the sealed speaker can into a sand pit pond with ckear water behind our house and the fish were definately drawn to the sound! What a great memory. 🙂👍👍 (I also had the 200 in 1 kit so its may have been that kit in which I tested the fish caller).

[@MorryB]

@@sailgoal Haha, I forgot about the fish caller! I think I first used it on my aquarium fish (they didn't care, lol) and then even tried it during a family ice fishing trip (with no success).

I got this kit in grade school (2nd grade) and studied that book obsessively (OCD?). I got my BSEE 15 years later :) thank you

[@BrettHoustonTube]

That is so cool! I had the kit as a boy. My Dad owned a Radio Shack franchise and was a communication engineer for CBS. That kit was a brilliant design and was so much fun. We created an electronic whoopie cushion to rig chairs for dinner guests.

[@MultiScrotch]

I HAD the 150 in One in the end of 70s !!!! LOVED IT !!!!! so much memories, thank's for this video !!!

[@RWKelley]

I had this model! It provided hours of fun. It also removed the mystery/fear of electronic components. I wished they made them today for my kids to use/learn.

[@RetroSpector78]

Maxitronix still makes a 200 in 1 model I think. An exact replica of the Tandy / Radioshack version.

[@michaelbauers8800]

Interesting, the 200 in 1 has some logic chips. The 150 in one had some simple IC, like an op amp?

[@coolelectronics1759]

@@RetroSpector78 radioshack had one recently before they went out of business and I just bought one brand new for $100

[@ctscantechnologist]

I learned so much about electronic from this kit. I wish I could have preserved mine.

[@7smr]

I still have this kit when I bought it around the late 70's from Radio Shack. I lost the original manual but I found a pdf file online and I will pass this on to my son.

[@b5bus]

I was an only child back in the 80s. I had this exact kit back then so I had a lot of time and fun with it.

[@muzzaball]

Thanks so much. I had that exact same kit when I was 10 years old. Great to see it in operation again. I made the exact same circuits as you did - I definitely remember those springs and components. Thanks.

[@MorryB]

I had this! The crystal radio project was my favorite. It blew my mind that you could listen to radio without batteries/solar power.

[@sdrc92126]

RS had a similarly built crystal radio kit!

[@hemiolabooks450]

Enjoyed that tour thanks. I'm restoring an early 70s kit, 50 in 1, wooden box, all germanium. Do you happen to know the coil voltage for the relays in these? I think I need a replacement.

[@genki2genki]

I loved this kit, but I just cannot imagine today's kids having the patience or interest. But I was fascinated.

[@CurvedVacuum]

Had one of these as a kid, got me into making electronic music which I still do :)

[@LayneRuley]

Had an 80s version of this growing up! Thank you so much for the great video! Good Content!

[@robvegart]

I had like 2 or 3 of these kits in comparable. Back when America wanted to learn and have fun doing it.

[@ronnyverminck1450]

Prices are not in € but in Belgium Franks. In those days of Tandy, there was no €. So, i think that invoice was for small components, probably a 9v battery and 2 1.5 AA battery

[@CassetteMaster]

I love how the PNP transistors are germanium!

[@rodsims8471]

This got me started in the magical world of electronics .. I modified Vox so when it heard a sound the relay would turn on my casset recorder then after 5 sec ( delay cap ) turn off .. ohh the fun I had with that … LOL

[@michaelbauers8800]

I had one of these. A cool set with a lot of stuff to try out.

[@robvegart]

As a kid some 40 years ago, I made the vox voice project, the colpitts oscillator, rc oscillator, the digital counter probe, the fm x-mitter, the am/fm radio, the crystal radio(probably everyone's favorite) the different meters, etc... Mines I think had a few IC's. 555 being one of them, and a few 4000 or 74ls packages... Might be 4066 and 4001 or 4002. I could be wrong.

[@raccoon874]

*the box art alone is nostalgia*

[@TheShamrock1234]

I had one just like this, spent hours playing with it.

[@OnTheRocks71]

Dang, I had both of those growing up, still have the 200-1 too.

[@braxma12]

I have bought the 40 in 1 electro magnetic kit science fair NEW and the connections are tarnished. I suspect even the wires... what do I do, Please help. Beautiful, spanking new and doesn't work. I tried 1 lamp with new wires and barely worked. So I know the components work, just 50 years old thats all...

[@adeshization]

where can I get these kits to buy new … or at least with everything included used ,.... guys please ?

[@Cyberpuppy63]

Just use the parts list given in the manual; label all the parts, and apply to a thick card-board backing. :) Home made!

[@3dsmaxrocks699]

eBay!

[@davidmonaghan958]

Loved them

[@tarajoe07]

These still exist in the form of "Snap Circuits"

[@burntoutelectronics]

Ah germanium transistors

[@michaelbauers8800]

If you water them, they grow into flowers. Or is that geraniums? ;)

[@dandanver7359]

I has this one :)
