- 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 TH-cam needs. Brilliant work Nate!
It's nice to know you have mini tv's in your camera, I had 3 broken one and now I have projects for all of them!
Robotan I seen some guy hook a video game up to a 1 inch tv like in the vid lol
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 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!
Tip: The smoothing capacitor mostly tells you the maximum input voltage range. Is it for example rated 6.3V, you can be sure it must be below that.
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
This is awesome! I've been thinking about playing with a viewfinder CRT, and this has set me over the edge!
I've recently gotten into electronics, and your TH-cam channel is my largest source of inspiration for doing so. These videos are always so interesting. I'm going to try to build a full theremin soon, which is something I don't believe you have covered in a video yet. I really hope it ends up working.
I would love that pocket o-scope! I have been getting into RC planes and cars recently; one would help immensely.
KilledWithStyle just curious what do you use an oscilloscope when working on rc cars/planes?
I am a little bit beginner and hobbyist when it comes to this so I like to know my homemade radio is working the way it should (so far its been guess work and hooking up devices that makes noise).
Honestly until I saw this, I never thought of making my own o-scope. Although at this point, it sounds like fun :D
I really like your channel. I think you are doing a really nice job of creating these demos. It's not overly simplistic and not overly detailed. You also point out good resources to use and safety guidelines (for the most part). You might want to have the text captions you sometimes add show up for longer in a gentler manner, but that's my opinion, you might be doing it on purpose. I think an oscilloscope like you reviewed would be a perfect way to test the pocket one you built. I'd love to get one of those and see how it holds up.
Thank you for continuing to make videos, I love your channel.
*Fffuuuulllllllll Bridge Rectifier* I want the scope.
FULLL BRIDGE RECTIFIEAAA
Electro BOOM ?????????
Mr.Skull: The King of creativity what about your grandpa?
Jake Mitch 😁😁😁😁😁
I love you and your content
Quality over quantity
Btw gimme dat oscilloscope pls
Always cool stuff from you, well done!
Great video once again mate! I really enjoy this channel.
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.
Gimme da oscilloscope!
I would love to get one of those scopes-
Amazing scope from the old camera. I love how you repurpose stuff. Your very inspiring.
I've watched your videos from Damn near the begining. Im a long time watcher. what i like the most about your channel is your so much like us normal DIY ers. No big budget just what we can salvage and redesign. Your amazing!!!!!!!
Thanks for all the great videos! I can't wait for more.
GIVVE MEH DA METAAA
jako3xb wrong channel 😂
FULL BRIDGE RECTIFIEAAA
Hauahauahauahauahsu
jako3xb Ey shawty, are u a rectifier? Because
GIMMA DA SCOPE
Noet Games Fan of electroboom?
full bridge RECKTIFAIAAAA!!!!!11
(EXPLOSION) i think so
Have u subscibed to him? You've probably eaten some leadpellets if u say no
My autocorrection is so stupid iT constantly change things so thats why Some things aren't good written
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!
Quite the fun little project to reuse some old parts. Big Thumbs up.
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
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
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
I love your videos, my son likes watching them too because they are great at breaking down complex ideas into easy to understand concepts.
Can has scope?
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.
I just started studying electronics last year and I love your channel so much! Keep up the good work :)
I love your videos. They are really informative and entertaining to watch! Keep it up!
If I say banggood sucks will I get a free scope?
Dave B Probably
GIVE ME THE oscilloscope to check the FULL BRIDGE RECTIFIER!
Is it free to China?
Nick Chemistry wrong channel bro
XD -electroboom-
Awesome video! I love watching these videos with my kids. Keep it up.
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!
I love your videos, they're so inspiring. They're what pushed me over the edge to finally buy my own breadboard and a starting set of components!
I love the stuff you build!
I have had a mini crt for a long time now and wanted to make an oscilloscope with it. Now I can! Thank you!
Love your videos. I have built quite a few of your projects along with you and could put one of the pocket scopes to good use. Keep up the good work
Awesome Video...Nice build on the scope!
I'd really get some use out of a pocket scope! Congrats on your sponsorship!
I love tinkering with electronics, and this scope would really help! Thanks!
this is an extremely satisfying video & with all due respect, i need that pocket oscilloscope!!
That is pretty cool. I love the random doohickeys you build.
I might have missed out on the o'scope but enjoyed the video quite a bit. Keep posting them.
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
Great video mate , keep up the great work.
I just made another one with a sony watchman. I thought this thing had absolutely no practical uses but this one works better than the one i made with a camcorder and because it was originally designed to be portable it was very easy to make simple modifications. It runs off 4 "AA" batteries and has a bigger screen with a brighter display! Thank you so much for this video. This new scope should help me understand what I'm doing with the circuits i experiment with!
The pocket oscilloscope looks great, keep up the good work
Keep making some really cool stuff and be safe
Hey man! Love the videos keep up the great work!
Great video! Instructions excellent and producible.
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!
That was... Unexpectedly simple... Nice job!
Well done. Fun little project.
Awesome, keep up the great work!
Cool little device you made there, it is amazing that you can make it from that.
Great video. Nice little oscilloscopes too.
Well done! Great project.
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!
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.
Another great vid. Thanks for sharing with everyone. Would like that Oscilloscope!
Those pocket oscilloscopes look quality to me. Great video bro.
Would LOVE one of those BangGood scopes! Great video!
MAN THIS IS THE MOST COOLEST KID EVER, i love doing stuff like that but i never really got out of my shell to do it, im always afread that im doing to get shocked and die, and man thats the coolest hand held thing ever i would love to have one if you have any more, Keep it up
As long as you discharge the main capacitor you'll be fine.. I think..
That pocket scope would be awesome to have! I am getting into electronics lately but as you said, scopes are pretty expensive if you're just starting with electronics. Keep up the good work!
Wow. Nice project. There was a project in a magazine that used a constant current diode to charge the horizontal trace capacitor. The diode was $10 in the 70's. I love the sponsors scope. It would make a nice addition to my bench.
Pretty cool project, kudos on getting the Banggood sponsorship. They're pretty cool guys, I just bought a load of drone stuff from them.
That oscilloscope looks great!
I actually prefer your homemade CRT pocket occiloscope, I LOVE CRT displays. Great video, keep up the good work man. 👊
I love watching your videos and always look forward to the projects you come up with! I actually got ahold of one of those little CRT displays a while back and made it into a mini night-vision camera. It runs on 12VDC from lithium cells, has a 3W 940nm IR illuminator on it, and uses a super cheap 720p NTSC CCTV module that I removed the IR filter from. I have yet to make a working oscilloscope, but I would love one of those Banggood pocket scopes!
Love your vids dude!!
Keep up the GREAT WORK!
Another cool video, keep on rocking.
Awesome video as always
Those pocket oscilloscopes look super useful for projects in the field.
Great Video! Thats great that they let you have a pocket scope! Thanks for having a great channel (:
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!
Awww such a cute little crt!
Hey buddy i love your channel! Keep it up!
Love the vids. Pocket Osc. looks nice.
Awesome little project.
very good video,thank you for all the hard work you do in making these instruction videos.2 thumbs up,keep up the good work.ps i would like one those oscilloscopes
Love your channel!
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.
you are so good at what you doing
Nice video, that mini crt is amazing! Lol
Sweet build!
Hello sir! Thank you SO much for all your knowledge and inspiration you share with the world! It means a lot since I am a slowly up-and-coming hip-hip rap artist and I'm doing my best to share real awakening, yet basic, knowledge and inspiration with the world as well. It would be such a step up to own ones of those pocket oscilloscopes since frequency is what shapes the universe! And that's what I want to learn to teach thru music. Also you remind me of one of my cousins. Lol. STAY AWESOME!!
ummm, yes. that looks amazing :)
And the mini cry looks perfect for making sci-fi sets. Very lost in space looking
Keep up the good work!
Keep up the great content :) 👌
Great video keep up the good work
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.
Awesome project!
Great project! I'm going to try to make this one... I've always wanted an oscilloscope.
I am a recent college graduate and active technical hobbyist. A pocket oscilloscope would not only be absolutely cool to have, but tremendously useful!
Neat scope giveaway. I could really use one. Thanks for the videos !
I love your videos and that oscilloscope is awesome
fantastic video m8 love ur vids
