- Saying CRT Tube is redundant as CRT already means Cathode Ray Tube... :P
In today's video, we take apart an old VHS camera to get the view finder's CRT display, and we use that to make a very small pocket oscilloscope. Thanks for watching! :)

Yay! You got my letter!!! What did you use to put it on the wall? And this is a awesome video
Haha I used a microwave oven Transformer xD thanks so much for sending it!! :)
Inventing Things I checked out your channel lol. Good stuff 👍
Denzel Morok THANKS! Im glad you like my videos. They should get even better soon
Keystone Science well im glad it wasn't plugged in xD. And no problem glad you enjoyed it
keystone science can you make a vibro-acoustics sound levitator? it would be awesome if you did it!
This is exactly what UA-cam needs. Brilliant work Nate!
I love your channel and use your projects to get my kids interested in electronics! I am an automotive technician and an ocillascope is one of those tools I haven't been able to afford to get for myself. That scope would make an amazing addition to my kit!
*Fffuuuulllllllll Bridge Rectifier* I want the scope.
FULLL BRIDGE RECTIFIEAAA
Electro BOOM ?????????
Mr.Skull: The King of creativity what about your grandpa?
Jake Mitch 😁😁😁😁😁
In the early 90`s I used an earlier model camcorder CRT (2.5 cm diagonal) in a similar setup, on the front side of an audio amplifier (built by myself) to give an interesting video display of the music. Those CRT`s were so good, that Panasonic used them to build miniature portable TVs... I wanted to build an oscilloscope using that CRT, but electromagnetic deflection limited the band drastically. Nice to see people still interested in old school electronics - a lot to learn from there. Nice video!
I am a recent college graduate and active technical hobbyist. A pocket oscilloscope would not only be absolutely cool to have, but tremendously useful!
GIVVE MEH DA METAAA
jako3xb wrong channel 😂
FULL BRIDGE RECTIFIEAAA
Hauahauahauahauahsu
jako3xb Ey shawty, are u a rectifier? Because
Those pocket oscilloscopes look super useful for projects in the field.
It would be awesome if you could make a Tesla coil like one of them in the background of your videos
There is really nothing special to it... Just two coils, capacitors and the transformers of a old microwave.
You can eliminate a lot of these factors rather easily... You can tune the coils by measuring the individual capacitance of the second coil with a multimeter, then adjust the number of windings to get a good resonant frequency (or just create some Leydener flasks, you can control the capacitance rather easily). And just replace the spark gap with an IGBT/thyristor etc. Expensive, but can perfectly be regulated with some sort of microcontroller (via a Darlington-circuit).
But yeah, a video about this coil would be nice, i am interested how good this makeshift toroid is... (I want to make a bigger one myself, but i do not want to get shocked by a f*cked up toroid).
Eulemit Beule wait you still call capacitors condensators
Christian Wang I can change it if it really annoys you... If you constantly have to change between german and english, there is a good chance you get something wrong from time to time.
Max Power ohhhhhhh that makes a lot of sense
I've made my own mini scope from the CRT's quite a while ago. They are fun to work with. When I was in High School, I made one out of an old TV, with the same use of the deflection coils.
My next project is to add two of then to my DJ setup, to watch the left and right audio outputs.
I have bought one of the LCD digital scopes from amazon. Very surprising how well they work.
I enjoyed the video you just gave. I watch them a lot, and have come up with some uses for the things you've shown us.
Thank You!!!
Michael
Wow this is really cool. Wish I had as many old electronics as you do to take apart. I love your videos. I just ordered some boost converters to build the pocket taser and that come in tomorrow. I can't wait to show my friends . Thanks for making these cool videos. They are very informative and teach me stuff that I would never learn in school
Also could you do a video about some projects involving 555 timers or 741 op amps? I have some but I don't know what to do with them
Jonathan Cluiss i ordered some too but i was wondering if you could use them in a tesla coil circuit
As an electrical engineering student one of those pocket oscilloscopes would be rather useful. Love the videos!
I'd love to be a runner-up for of of the miniature Banggood oscilloscopes. I can't seem to find anyone with an oscillascope to get hands on experience with it and I'm holding off buying one that's a four pronged analog until I'm familiar with the basics.
*Studying to be mechanical engineer but trying to dip my toes into electronics and programming a bit as well
taking a bite out of a load of fields there! you might be interested in eevblogs channel?
I'd call it a nibble instead of a bite to be honest. I'm slowly making my way around the each basic electronic component to make sure I don't skip over anything. And programming (c++) is a whole new world. Saying I've taken a fraction of a chunk out of either one would be foolish of me XD And I've already been subscribed to eev as well. Going through his Friday Fundamental videos currently.
And if someone's wanting to publish my novel long comments make sure to get in touch with me.
Just found the channel thanks to the back yard scientist. Great content! It inspires me to want to tinker with electronics in my spare time. Keep it up!
This is awesome! I've been thinking about playing with a viewfinder CRT, and this has set me over the edge!
How dare you say CRT tubes, that's redundant. Kidding I assume you know, your probably super smart, lol. I also would like to enter in the giveaway. Cathode ray tube
Cathode Ray Tube Tube - lol
Pretty cool project, kudos on getting the Banggood sponsorship. They're pretty cool guys, I just bought a load of drone stuff from them.
I love you and your content
Quality over quantity
Btw gimme dat oscilloscope pls
That was... Unexpectedly simple... Nice job!
That small oscilloscope is really neat. It would be handy for testing devices when the measurements don't have to be as good as with a $5000 oscilloscope. If it breaks it isn't a big deal since it isn't that expensive.
Cool idea using the viewfinder from a camcorder for something! One could even calibrate it with the commercial oscilloscope to be able to make some sort of measurements, but having a frequency option would be really useful.
Gimme da metar!
I need a scope... 360 noscope is just no fun
I realized. One could actually use this little CRT tube in conjunction with an A/V camera, and make a scope with it.
That is pretty cool. I love the random doohickeys you build.
I find this funny because just yesterday I was looking for an affordable oscilloscope to measure the power of the EMP I built based on your design and I couldn't find anything decent under 75$. Glad I didnt decide to purchase anything yet. Love your videos btw and how you give a understandable yet detailed explanation on all the gadgets you build for people who are not as experienced as others> Keep up the good work and I would love to see you experiment with high powered lasers!
GIVE ME THE oscilloscope to check the FULL BRIDGE RECTIFIER!
Is it free to China?
Nick Chemistry wrong channel bro
XD -electroboom-
I started playing around with electronics just a few years ago and an oscilloscope would be such a cool tool to have. Especially if you don't want to pay all your money for it.
Quite the fun little project to reuse some old parts. Big Thumbs up.
Balsa wood + HV = fire HV + pixie mover = smello scope. Good job keystone "keyp" up the good work.
Can has scope?
Just discovered your channel, and I love it. You remind me of an easier to understand bigclive mixed with electroboom. Keep up the good work dude
Those pocket oscilloscopes look quality to me. Great video bro.
I used to have one attached to my car instrument panel, and the frequency was based on the revolutions of the front drivers side wheel. the faster you went the faster the waveform moved. real cool
Awesome
I might have missed out on the o'scope but enjoyed the video quite a bit. Keep posting them.
I'm an electronics hobbyist, and I've wanted an oscilloscope for monitoring the signals sent from pagers that I received on my DIY short wave radio for ages. Anyhow, I've been a big fan of your work for a while now, and I was even around when you made your original oscilloscope from a CRT TV, I tried it, but blew a component when accidentally powering the wrong pin :P (my garage/workshop smelt terrible for days)
Very cool! I appreciate that you assume I'm not doing this for the first time!
I actually prefer your homemade CRT pocket occiloscope, I LOVE CRT displays. Great video, keep up the good work man. 👊
I'm going to dig around for that old videocamera I used to have. Also, commenting for a chance at the pocket oscilloscope - compact and super useful!
The pocket oscilloscope looks great, keep up the good work
Cool little device you made there, it is amazing that you can make it from that.
Wouldn't mind having that oscilloscope, really cool little tool, might even buy one
I LOVE KEYSTONE SCIENCE
pocket oscilliscope
I think its amazing how small they could get these CRT tubes. When I first heared that they used CRT tubes in these camcorders I was pretty amazed.
I'd love one of the oscillioscopes, they are awsome!
this channel reminds me of Cody's Lab. Both of you help keep me motivated to learn electronics and science.
I'd be very interested in receiving a pocket oscilloscope. I've been needing one for some random projects I've been planning/doing.
this is an extremely satisfying video & with all due respect, i need that pocket oscilloscope!!
Thank you for continuing to make videos, I love your channel.
This is such a neat idea! I had no idea those little CRTs could be powered with just 5 volts. Also that pocket oscilloscope is really neat, seems to have a bunch of functions for its size and price, I would love to have one lol. I do have a much older, bigger oscilloscope - an eico 435 from 1965 that I bought from an antique store. It works pretty well considering its age, but there's a little interference at lower settings, I'm thinking an electrolytic capacitor, possibly the filter, went bad, as they do on older electronics.
This is a neat project. I will say though, if you can't get a salvaged camcorder there are kits you can buy that let you build a pocket oscilloscope. They are fun little soldering projects from what I've seen.
a tiny oscilloscope would actually be extremely useful
Great little pocket Oscilloscope.
Cool video. The pocket scope would be great for scoping camshaft and crankshaft sensors.
Yeah! An oscilloscope would be awesome as I learn electronics! Hope I am fortunate enough to receive one. Thank you Keystone Science and Banggood. 😃😃😃
I love your hammer you used to nail the letter to wall! A mot!! I love those things. Also I really enjoyed this tutorial about pocket oscope cause man that one you're giving away looks nice. Plus it pretty cool how the crt used runs on 5 volts not high voltage!
Excellent project, when I was going through college I was going to build something similar using a 555 timer as the horizontal sweep timer and enter it in a 555 competition, unfortunately due to studying and exams I never got to do it. Keep up the good work!
Also, I live in Niagara Falls, we have a nice statue to Tesla as the hydroelectric power station he designed is here.
I desperately need one of those pocket oscilloscopes.
I didn't even know they made pocket scopes. I would really like one!
The only thing I would have tried was keep the internal mic and used that to modulate the coils, then it would be truly handheld. Nice job.
I remember seeing some video where someone was gaming on one of these. This oddly seems like a somewhat more practical use. But more realistically just cool.
That magnetron hammering action tho!
Ooh I'm probably actually buying that small oscilloscope!
My niece is really into science stuff so your videos help me do more with her... I am currently looking for an old microwave to get the transformer out of
That's cool, I didn't even realize that old camcorders had crt tubes for the eyepiece.
I would love that Oscilloscope. It would be a very useful tool.
Whoa looks like a cool effect for listening to minimal
Awsome project. I was amazed it ran on 5 volts!
I would love to have one of those pocket Oscilloscopes. It would come in handy building a theramin. (Another project my son wants to do.)
Would love the oscilloscope, as I'm getting into electronics and would help me greatly. Thanks for the video!
I'm putting this comment in so I can hopefully win an oscilloscope, but since I'm here I would like to say that I love your how to videos! Keep them coming because I like learning these things that you are showing us all the time!
I would love that SCOPE!
Thanks for the idea, it's look like retro futuristic things
i recently found your channel and loving the crazy stuff you make i especially like the way the videos are put together short but still informative without being boring
I want one of those pocket Oscopes.. would be amazing fun to use at work and on DSP projects:D
Thanks for all the great videos! I can't wait for more.
As a startup electrician with multiple labs (one at home one at school), it would be amazing to have a portable alternative to the oscilloscope at my campus :D
Awesome little project.
Finally a use for my tiny CRT.
One of those oscilloscopes would be a life saver for doing my projects at home for my electronics and computer technology major😃
once again, great video! can't wait for the ion propulsio device and tesla coil gun! also, this is my submission to enter the drawing for the oscilliscope... keep up the good work!
Oh boy, I hope I'm not late. I enjoy your videos and I certainly wouldn't mind a oscilloscope to learn with.
I am new to electronics and I want to study on nature of waves so I will certainly want the oscilloscope it's all up to you
Cool little scope and the one from Banggood would be a good small scope as well.
I would love an oscilloscope, great video btw!
Getting one of the oscilloscopes would be extremely cool since I haven't got an old camcorder to turn into an oscilloscope myself.
Keep making some really cool stuff and be safe
This is fairly interesting
Now I regret passing up that old studio camera at the secondhand shop even more.
I would love one of those oscilloscopes!
Thanks for the video. Your videos are entertaining and educational at the the same time. I also like Tesla and I think that he was a great inventor and was way undervalued in his time.
Love the video's you make, this one in particular reminds me of how I've always enjoyed tearing things apart even as a kid. I am 16 years old and very much enjoy the electronics field and circuit building. I always find it very entertaining and inspirational to find channels like this that produce content that teaches you and gives you some creative ideas for projects. Keep doing what you are doing and producing great content. Would love to have on of the pocket oscilloscopes. Thanks.
I would love that pocket o-scope!
Interesting! We we need a little work to add sync. On another point, while the brightness was more that adequate focus looked a bit blurry! Also, a fundamental limitation is imposed by inductance in the coils the reactance of which needs to be substantially less than the output impedance of the signal source. But, if it can reasonably cover the audio band, we would have something worthwhile for sure!
I would love to receive one of the Oscopes. I'm currently in high school and working through some electrical engineering courses at my local college and this would help my studies. THank you
I just started studying electronics last year and I love your channel so much! Keep up the good work :)
Be really keen on one of those pocket scopes, its the one thing my test bench is lacking and it really shouldn't be with some of my crazy projects. i don't have room for an oldschool scope, as it is my power supply takes up more space than i would prefer. building things like induction heaters and tesla coils, from recycled components where possible.
Awesome, I'd love to see more experiments with ion propulsion
Thanks for this project . I have all the components to do
this project. Hopefully I can get the time to do it.
Cool idea to make your own pocket scope.
Another great vid. Thanks for sharing with everyone. Would like that Oscilloscope!
I love watching all of your videos, and an oscilloscope would be really useful
I'd be A-OK with getting one! Your videos are awesome.
you are so good at what you doing
