Who? Who would give this wonderful man a thumbs down? Carlson has effectively revolutionized the way I do electronics. We are so fortunate that he is willing to spend the time to teach in such a didactic and clear manner.
Trolls..Stupid little trolls is who With nothing better to do
👦
Bubbatech Electronics look don’t try to understand. Cats savers, you know, they get almost dead cats and bring them to life, get thumbs down.
lol shit cats are cool little critters @@chauffeurmarco
I think a lot of thumbs down are accidental. UA-cam should have a confirmation button for thumbs down.
I was just thinking the exact same. It disappoints and frustrates me viewers would give him a "thumbs down" when he donates many hours to provide us with FREE valuable content. The very least UA-cam can do is hide the number of down thumbs. All it does is potentially discourage the uploader from providing us with more to watch. Anyway, it is what it is. I'll just continue clicking like for vids I enjoy or simply clicking on another vid if i don't, never the dislike.
You make me realise how unintelligent I am. On another note, you really should do a kickstarter campaign for this. Designs like this are normally never explained to the public. Simply amazing.
Thanks for your kind words Daniel!
I don't suppose you could upload the board layout to easyEDA? Its quite an amazing site!
easyeda.com/
I haven't seen any negative comments, so what's with the 'Thumbs down' the man is not only very clever but he has the ability to teach, which is a bonus. Thank you .
Oh my god. Mr carlson i absolutely love and appreciate your videos so much. I have always been an electronics junkie since i was a little kid and have done quite extensive repairs and built circuits of my own for various projects. All of my knowledge is self taught through reading and trial and error but most of my good fortune i think comes from having a very meticulous nature. I can do a lot but there are gaps in my knowledge. It is so difficult to find explicitly detailed and thorough, intermediate and advanced electronics information about repairs for free for someone like me. (I wanted to become an EE but life got in the way.) Your videos help me immensely. You are by far the most knowledgeable, the most meticulous, the most intelligently logical in your decision making as per troubleshooting and when i am watching your videos i feel like i am finally getting the opportunity to shadow a briliant mind and peek in on the process. Thank you yet again sir.
Mr. Carlson, I sure wish I had had you as an instructor when I was going through Aeronautics school! 55 years later here I am learning more from your videos that what I had learned back then! I know the world of electrical engineering and especially HAM Radios of which I am living now is so fascinating and ever evolving! Thank you for lending your knowledge to all of us!
Built the circuit with BC547's and slightly different resistor components (what I had available). Built it on perforated circuit board and connected it to a previously built low noise headphone amp. Housed in a mint box (not an actual cylindrical probe). Had a lot of trouble shooting to do in view of sloppy soldering but finally worked pretty good. Can sense a 40 watt fluoroscent light from 2 m away. Thanks Mr. Carlson for sharing and the explanations given. Much appreciated. Have a great 2017.
Take my Money!! Make this a Kit, and I will buy it! Outstanding project!
I agree with you Mike Dillion. I can do SMD devices but some are actuall too small for my old eyes.... I wish he would sell the them ... I would buy one in a heartbeat .
Hello, im not electrician, but would like to buy two of them.. one for friend.. i have alot of noise in my apms coming through speakers. Like videos even i sometimes understand what you say and geting new information, its very useful, thank you.
I would buy one in a heartbeat. I wish he would do a kickstarter for it. There’s nothing like it out there that I know of.
@@Budro4764 I'm an oldie also. I'm just self teaching myself electronics and I need to get one of these so I don;t electrocute myself or mess up anymore stuff.

A great learning experience. Super Probe is an amazing invention and a real time saver. It would be great if this probe was available as a kit that can be assembled, or as an assembled unit for purchase.
A great approach to troubleshooting a variety of circuits. The major advantage, no direct contact with the isolated area, which means no loading of the circuits, a huge advantage when troubleshooting tricky issues. Well done Paul! very professional construction and design.
if you ever write a book or if you ever do a paid course I will buy whatever you put out. I hope you understand how amazing you are as a teacher. thank you so much. truly amazing
btw I think I'm going to make mine dead bug style in a copper pipe with the shielded coax out the front
Thanks Nathan!
He has plenty on patreon apperantly. As soon as my economy allows i will join. He has a few designs i really wanna build for my newfound hobby ♥️ 4years late reply, but i dont know if he had that option back then either. 👍
Gosh, you really do run THE most splendid electronics channel, I bow and tip my hat to you. I wanted something just like this back in the 90s, to pick up POTS telephone line audio from the line cord; I would assume this would be sensitive enough to do so?God bless you, thank you for all your incredibly hard but rewarding work.
Thanks!
Mr Carlson's Lab You're welcome - a REAL component-level engineering professional, not a "module-plugger" as my ex boss calls them, haha!
+Mr Carlson's Lab I know some things about working with electronics, but watching your video's? That has taught me quite a bit. I really enjoy them & you explain things very well. Thank you
+unlokia I can't agree more. "Module pluggers" drive me nuts, those who brag about their "creations" like they engineered it. Using modules is just fine, but why try to look like a pro if you aren't. I rearrange my schedule when Paul uploads a video :)
MrJohhhnnnyyy The 'net is overflowing with enthusiasm for Raspberry Pi, Arduino etc - it becomes somewhat tiresome sometimes, as many of these folks think THAT is "electronics". Yes, they *contain* electronic components, but the user didn't design the Pi, the foundation did, and you don't need to know much (if anything) about Ohm's law or junction drop to know how to connect a Pi to a PSU, power it up and write a script that drives a GPIO high or low. I don't want to come across as an arrogant pleb - it's a really good thing to have a passion, but when REAL engineering and electronic design is swamped by the latest, lowest common denominator "trend", it fast becomes a facepalm moment in engineering.
I ain't an engineering snob, but software isn't engineering any more than a toothpick is a broom handle. Real engineering is stringing together discrete components and designing something yourself, or fault-finding - both of which Paul does with aplomb!
Right, I reckon I've waffled on a bit and I now sound slightly pompous, not intended... so I'll walk away with some humility left. :)
Oh, yes - I would (and just tonight, HAVE) set aside an hour or so to watch these superbly narrated and compiled works of art that are his UA-cam videos - kinda got a bit worn out hearing a certain Australian ranting and screeching, as nice as he is, it all tends to get a bit wearing and sameish... and I can't bear to hear pompous "opinions" - I'd rather just hear engineering and diagnosis, since that's what you're there for, no? :-P
God bless you all.
I know nothing about electronical stuff, but I do enjoy your and other peepls videos. I will keep watching because I will learn bit by bit
Boring and Stuffy. Reminds me of my HighSchool electronics teachers' names
Mr Carlson is the teacher I wish I had wayyy back then.
Massive thanks Mr Carlson! Another absolutely must-build for my workbench in my lab. Many years ago when i worked after school for a repair shop it seemed we were always using the professional model signal tracer but as time has passed and the kinds of gear i work on the idea of using one has just gone out of fashion. I can see so many applications for one once again (rather than pulling out the 'scope etc) with extreme sensitivity as this design offers... just need a bit of spare time to do it justice!
I have been a electronics tech for 32 plus years. Would have liked this years ago. Nice work. Enjoy your channel. Keep them coming.
Glad your enjoying Dave!
I am like a kid on Christmas morning when Paul releases a new video.
Thank you.
Not long ago, i used an RIAA MC preamp connected to a very simple probe, ( an audio cable with a little isolated antenna at the end ) to do something like that, to find where the audio path of a reel to reel recorder was broken. I had not seen this video yet, your probe is fantastic!!! Really, i can't understand the thumbs down on this video...
Perhaps a guy with low/no interests on electronivs.....
I resist calling anyone Mr. but I am in awe of you, Mister Carlson.
Merry Christmas from Poland to you and whole whole USA . Thanks for all your fantastic video's .
Damn, my jaw was on the floor when you were assembling that probe box on top of the speaker. From the PCB to the slick enclosure, that's some badass work!
Thanks Rob!
I finally got around to building a version of your super probe ! Built dead-bug style on a copper plane, and then fitted down an aluminium tube approx 17mm bore (you're Canadian so you will understand mm !).
I machined ends for the case from solid ali, and had to machine a tiny control knob to thread into the switch for complicated assembly reasons. Mine has the probe gain pot in a tiny box at the far end of the probe coax, which then plugs into my workshop audio amp, and takes supply voltage from there too. The probe works exactly as in this vid of yours - I can't believe some of the signals it has sniffed where I had not expected any to be :o)
I have photos of my version if you are collecting them. It was certainly a challenge getting a non-smd pcb to fit down such a small tube !
Great! I'm glad you enjoyed the project!
This is also useful as a short or open circuit detector, e.g. to trace broken wires inside audio cables. It's accurate up to a couple of millimeters ;) Very useful! Thanks!
Incredible video! You are a Grand Master. I would buy one of these from you in a second.
In the far past I made a circuit that use audio converted from 1/ohm, for locating shorts but this probe is a most have. Thank you for all your illuminating work and its B12 injection of wisdom and knowledge. Wish you blessings and time to spend them!
The Best Engineer Designer on Earth.....thumbs up.........
Thanks MrMac!
Great video, and what killer little probe made with very basic jelly bean parts. I shared this with some colleagues, across the pond. Roly, said, maybe put a FET on the probe input, for less hiss, and better performance, but he was still quite impressed with it. He used to run a company called Mitrex, that made sound systems for discoteques in the 1970s. Thanks!
When you see someone teaching you how to do something that nobody else is doing, something so cool and handy; subscribe.
I saw this video last week and started collecting parts immediately to make one. The transistors and output amp were not so readily available in the UK. I substituted 3904 for the transistors and slightly reworked the output to accept TDA7052. It works prefectly. What a fantastic tool . You sure know your stuff, you seem too young to be so knowledgeable. I have watched many of your videos now, some of them twice over. A+ all the way.
Thanks Mr. Carlson for your great videos, even Tesla would be proud of you. Greatings from Sweden, thumbs up....
Just an extension for those who can't read a scope or any number of simplistic instruments.. For that fella down the list here explaining really that all his time learning theoretical analysis of circuit theory, there is an avenue of a good techincian called having an "astute" ability. You don't need 4 years of calculus to dream up this project, as it's many small test devices rolled into one. I've even gone to simpler routes to repair even more complex tube radio receivers in my own electronics shop long long ago. Mr. Carlson is an astute person and may have been all his life. Hats off to him. For those who don't know the word, look it up. Still, I have to give him an immense amount of credit passing his knowledge to so many others via the power of the internet. As for compiling a book, I believe the days of circuit building as well as kit building is over. That has had it's day. It's all instant self-gratification these days for the most part without putting much into effort in anything.
Do a kickstarter and build them there’s nothing like that that I know of. Very cool, you’re a genius with all the test equipment you have invented.
Just ordered all of the parts to build your probe! This will come in handy in the future. Thank you!
The new "Ultra Probe" has just been released on Patreon, you may want to build that version, it's much more sensitive.
@MrCarlsonsLab can I use this to find the location of a break in a trace under the laquer on a board?
Mr Carlson, thumbs up for this design. From the 60's I mostly had to form an image of the working of audio equipment in my head, but in this video you have put a new compressed view trough my ears. I think that you've made not only a useful troubleshooter, but as much a very educational tool.
That is a cool probe. And you're right I can see it being used for all kinds of test. Thanks for sharing with us. I know I speak for many by saying, this probe will help our diagnostic time immensely. Thanks again!
When I was a teen I took a neon light tester and put one lead on the chassis and the other lead on an earth ground if the neon light lit up, I just reversed the plug. and no more hot chassis, thats how I kept from getting shocked. I didnt have a transformer I didnt have much test equipment just a VTVM by Heathkit and an Oscilloscope by Eico. I only fixed radios I didnt want to get into TVs just yet.
Another wonderful learning experience provided by Mr. "Wizard" Carlson. Thank You sir. I'm a Patreon member now! The information there is just mind blowing, and for only $2.00. Thanks again Mr. C.
Welcome aboard!
Hands down the best electronics channel on UA-cam!
Thanks so much for all your hard work. I really love the clarity of your explanation and your circuits are always super reliable. BRILLIANT!
Looking at your videos I wish I went into electronics engineering.
Excellent, thanks.
Thankyou for your instructional videos, I have begun some simple ham radio restoration projects and found a new avenue of the hobby to pursue. You are an excellent presenter and instructor!
Paul,
I really hate to grade your videos, but I consider this #1. Absolutely awesome and well done. Thanks. WB3BJU
Thanks Donald! Your opinions are always appreciated.
A+ EXCEPT for one bothersome detail! I am from New Jersey, USA. I have spent all of my 76 years hearing only one pronunciation for one of your favorite words, solder. When you say the word the way the English often do, with the letter "l" not silent, it sends me into spasms. LOL But the darned videos are so habit forming, I'm forcing myself to accept it despite myself. I know it's VERY American to talk about our quaint habits, but I will bet that the majority of the viewers (???) might agree with me. I wish I could SOLDER my ears shut! KQ2E
Hi Paul. Just a quick note that after so many time I now built this probe and it works amazing. It really speed up the process of trouble shooting. Thank you.
You're very welcome Mr. Driessen!
Projects like this are excellent and a great ways to learn about EE. Thank you so much for making all your videos and taking the time to explain the design process / physics behind all your circuits. This one was especially helpful for me!
Mr. Carlson = "the electron whisperer"
The very best explanations I have ever heard. I have been learning all this stuff from the 'school of hard knocks' since 1949. Your explanations are all very clear and understandable.
You are not kidding when you state there are lots of other uses. I have been using an inductive amplifier to trace noise on power circuit lines in commercial buildings. This is just amazing. Thank you sharing.
Hi Paul - that was a great video. I can tell you just live for electronics. My job for 45 years was electronics and systems. I must say you remind me of me and how every day at work was just another day at my favourite hobby. Nice work from start to finish on the super probe and the demo was the icing on the cake. Super.
What a beautiful project!! As always Paul, your work is so amazing, engineering clean and A+++ quality. I can't wait to build my own. Would also make a neat first PCB etching project!! Thank you so much for always sharing your superb expertise and "Tech Secrets"
A short piece of copper tube works well, although I put heatshrink around it or otherwise insulate it to reduce the chance of shorting something or getting shocked by being well grounded.
I also like using felt tip markers as probe bodies. You'll need to shield them internally. There are some interesting marker bodies, especially for highlighters.
Mr. Carlson, I have to admit I'm a huge fan of yours (and a recent one at that). I've always been interested in electronics and computers, but I was never very much interested in academic pursuits, and due to family connections I spent about 10 years of my adult life applying practical computer network architecture to offer affordable business and customer management solutions for healthcare professionals, along with picking up the sales, support and other needed skills to grow the business. I often find myself wondering what projects I would be working on if I had taken a different approach, one that had me working with a more technical understanding of electronics engineering, and I have to thank you because your videos have taught me so much about electronics, from soldering tips to abstract concepts I never thought I'd fully understand. For that, I tip my hat to you and thank you again for sharing your wonderful knowledge about the foundation and inner-workings of our connected world!
I'm also a licensed ham and I must also confess I've been absolutely mystified by radio since I was really young. I often found it fascinating that we could send information through the air, and to my young mind this was what real magic was about, so I made it a point to learn exactly how that works. It's hard to pick one single thing that I'd like to study but if I absolutely had to, I'd like to really understand how some RF amplifiers work, and some key design goals to have while building one. Also, what are the key differences in circuit design between audio and RF amplifiers? Is it practical idea for a project to start with an audio amplifier and convert it with the aim of making it work on any of the ham bands, and if so in what modes?
Hi Ahmed. Converting an audio amplifier to an RF amplifier, or transmitter really isn't feasible. RF circuits require tuning, and depending on the frequencies, completely different PCB layouts that tailor to 50 ohm impedance's... so on. Most audio power transistors are low frequency devices.
Paul, you and your videos are fantastic, but this one was especially meaningful!! I own quite a few of the items in your lab (along with lots of antique technology going back to the late 1800's & early/mid 1900's) and exhibit a lot of it at schools, museums, Maker Faires, etc. It was projects like your Super Probe that got me into science as a kid and inspired me to become a science instructor as an adult.
When you brought your Super Probe close to the detector tube of that sweet little superhet and the radio station crackled into existence out of seemingly thin air, I felt as giddy as the very first time I ever wired up a simple transistor oscillator as a kid and heard its mysterious little voice start singing!
And listening to the secret sounds emanating from the CD player reminded me of when I would spend hours scrolling through the shortwave bands with an 80 ft. wire strung out of my bedroom window to a tree as a kid listening for strange sounds coming from distant and mysterious beacons and data burst transmitters.
A question for you... Once built, would you mind if I used this in my science shows and events? I would even credit your channel during my live shows and classes. I want students to feel the way I did as a kid, and the way I did again during this video!
(Note: I present science shows, classes, and camps-featuring physics, chemistry, and electricity-as well as antique science & technology exhibits to youth all over the state of Texas. You can see what I actually do here: www.scienceshows.tech)
Thanks again for reminding me why I love electronics. I can't wait to build this! It's a treat that you're sharing your creations with us. Keep up the great work!
~Daniel
Thanks for your kind words Daniel, It's fine for you to build this and "show it" at your science shows.
@@MrCarlsonsLab These great questions, comments and your replies give me hope for humanity. Well done sir.
Excuse my "French", but you sir, are an EE badass! And your build quality is superb. Marie's graphics are also lovely. Really enjoyed the video facts in the description. Only I'm now wondering about that custom microphone. ;)
Back in the old days, an audio 'engineer' was usually an electrical engineer, as well. When you needed something, you built it. When something broke, you fixed it. So many off the shelf solutions available for audio people these days, half of the artform has been lost to the dustbins of history.
I can understand the use of the ART piece; Applied Research and Technology makes awesome gear at a price that's almost a steal.
Cheers, this was an amazing video. Thanks for all the time and effort you out into your channel. :)
Thanks for your kind comment, Marie says thanks too!
Great Project! It makes me happy to see how generous you are by sharing your founded knowledge gathered over years. IMO it's rarely these days. Many thanks for this!
My humble compliments on your clarity of expression, and understanding of electronics technology. Also a warm appreciation of your generous sharing.
Have a Happy Christmas and a Merry New Year.
Thanks. Merry Christmas!
I know i already thanked you for this video but i just cant help myself, i need to do it again. You are the best most completely thorough and knowledgeable instructor. Thank you.
You're welcome!
I may have to apologise for the rude words I said about you Paul in regards to parts this circuit. However they were said in a complimentary fashion 😊.
I have been building a cut down variation of your Super Probe, (through hole on vero board). When I found that the two simple 3904 stages at the start of your circuit produce 65-70db gain I was pleasantly shocked. Even a 1.5mV signal was producing an output of 4V - 4.5V. Granted it was very noisy - but recognisable. Anything lower than 1.5mV was lost in the noise, while 2mV was clearly identifiable.
Thank you Paul.
This looks like a very useful tool that I need at my fingertips! I love the light bulb protecting the VR from shorts! Great work, Mr. C!
Thanks for your kind comment Anthony!
Dang it, aren't I glad I became a patreon. I must say you've got a treasure trove of knowledge there. Thanks!
excellent video, one of the very best DIY electronic test equipment videos on youtube,
Wow ! You are amazing and have a great gift with all of this. I am so glad that I found you so I can continue to watch your videos. Yes I will start looking for some old probes and test equipment when I go to the next hamfest. I agree with some of the other people that have asked for a kit. Thank you.
Paul this is exactly the kind of probe we been looking for... now if I can just get one of the young guys to make me one!
Hi Everyone. All the Files to this invention are released on Patreon as of "NOW!" There is also an instructional video aiding assembly. Join up and learn things about electronics you won't learn anywhere else. Here is the link: www.patreon.com/MrCarlsonsLab
EDIT: The all new Carlson Ultra Probe has been released on Patreon with all the files. It's more sensitive that the Carlson Super Probe, and has higher bandwidth, check it out at the link above.
I think he said that he super glued it with a single dot on the backside of the board.
Neat trick with that incandescent protection bulb. Don't want to let that factory installed smoke escape! That can be a problem. ;)
I'd be interested but I don't own any valves of any kind or know enough about there workings of them. Thats why I like your content. Old school but new at the same time.
I prefer through hole and non surface mount stuff like switch mode power supplies!
Love the videos that you do tho and am very interested in the design/idea/concept of the probe. But I would have no use. I don't trouble shoot radios or signals to this degree (RF Stuff).
You should have done a kick starter for it!!! Why didn't you?
This link just seems to go to Mr Carlsons Patreon home page, does anyone have a link to the actual files? I have been searching on Patreon for what seems like days with no luck so far :-(
Maaaan you are brillian, I wish I have this tools when I started to repair electronics 32 years ago 😏
Mr Carlson is like the Mr Rogers of electronics - he takes all the terror out of it. Such cool vids!
Hi Paul, Have you ever worked as a technical instructor in a tech school or college environment? I think you would be a very good one. It's also pleasing to my ears to hear "Soldering" rather than "Sodering".
I have a small job shop so I do a lot of machine work. I love playing around with electronics but I'm not any kind of expert. your videos are just excellent. I appreciate your ability to explain things in a basic way. you have helped me over several hurdles so far. Thanks for your time and efforts to share your expertise. it is truly appreciated.
Glad your finding the video's helpful!
amazing design. no need for audio mode and switch. it could have a small Li battery and small speaker all in one probe.
You are so sharp when it comes to this subject. Just watched one of your power supply videos and your ability to read the circuitry so well like it's second nature is a rare skill indeed. You're the Steve Howe (guitarist) on the bench.. I joined your Patreon and will step up the level soon. And yes - I'll be making this one.
This is a very clever little circuit. The I/P Z is very high as is the gain of each stage of amplification. Normally providing base bias via an open resistor is a big "No-No" in transistor amplifier design but in this case it works perfectly. Next project is to build one. Nice one Paul.
This super probe would be a very cool bench addition. Too bad it isn’t available as an assembled unit or a kit. Thank you!
I may make a run in the future, I'm also in the process of designing an "Ultra Probe."
Mr Carlson's Lab, anything available yet? Would love to purchase one of these. Or at least a kit with a populated board?
Hi
Paul , I finally got around to building the non contact probe amazing thing, now retired I'll have a go at the super probe. Paul
Such an awesome device, Mr. Carlson. And as always, and in-depth and incredibly thorough walkthrough of the technology and concepts involved. Excellent job, thank you.
Thanks for your kind comment!
Just brilliant , well done Mr. Carlson
My first oscilloscope was a 1MHz tube CRO bought at a yard sale at an old TV repair shop. It came with several probes like this, RF sniffer and such. It seems to be a forgotten test instrument. Thanks for doing a video about this.
Still one of the handiest tools I have........just a no brainer piece of kit if you do anything audio or Radio.......
Great video Mr Carlson, I generally skip through some of the boring stuff in these video's but I had to watch your video's from start to finish. Thank you for sharing.
Glad you enjoyed Billy!
I wish I could of seen this about 30 years ago when I was doing this for a living. Very nice presentation, thank you!
Hi,
once again, you did a really interesting video that explain well how it work.
i'm French and learning electronic. in french it's hard to find interesting video like this
Thanks a lot
That was extraordinary! Well done Paul. I have to make me one of these. Ever thought about writing a book with all your designs? And selling it? I would buy it.
Thanks Buddy! That would be a big book. Possibly one day, but for now I'm happy to share.... Makes for good video :^)
Thank You for sharing Paul! I always feel like I learn more from a good teacher than a book although like Buddy if your knowledge was only available in a book I would buy it as well.
I would also buy this.
Maybe not all your designs but the ones that would benefit beginners. I realize you will have to write explanations for the designs and that could take a while to polish along with the schematics.
Oops wrong thread
Finally a tec teacher that talk's MY language great channel.
Incredibly awesome kind Sir. Thanks Paul for what you have shared with us. As always, you are a "Cut-Above".
I built the non-contact probe and it works great! Thank you. Another tool added to the arsenal.
Hello thank you very much for sharing your circuits on you tube.
I think the super Probe is realy fantastic!!!.
i am getting all the comonents together to Build this Device, .
I am using 22mm copper pipe for the probe body and 22mm end caps for each end of the probe body!.
I realy enjoy watching your work thank you.............
This is a great device.Should be able to buy it as a diy kit.That is easy for those that dont have what,s needed for etching a pcb.absolutly somthing i want in my tool box for audio gear fix.Genius!
Great scott! Make kits and sell them please. If you are afraid of liability, include a disclaimer that your are not responsible in any way for how the kit is used. Or if you don’t have the time, please find someone to create these kits for you. It would be great for us service techs and put money in your pocket as well. Please consider this Paul. Not all of us have the time to hunt down all these parts, etch boards, etc.
Thanks for these videos, unpretentious gerous sharing of your knowledge and ideas, between yourself and Xraytony I dont need to else where to be entertained, very informative and educational. So many videos to watch !
Absolutely a gem of a video. This is useful in so many ways, including learning.
The only minor disappointment was the lack of a smooth finish on the metal probe body.
Love your true inventor mindset, rare these days in its pure sense. Thanks, very cool product!
I am surprised about how many noises there are in that little cd player! Great video as always!
Thanks! I never knew such a simple tool could have so many uses!
Nice project, good work. I can see how useful this would be in troubleshooting.
You can tell he's a real tech too. Running a 4:3 monitor w/Windows XP.
Yes, "if it ain't broken..." :)
Makes sense to buy cheap if you're going to be waving high power RF around near it. PCs struggle enough with dirty mains.
And a CRT makes it just perfect. No need to buy new software, OS, or hardware...
thank-you very much Mr. Carlson. yet another very good video. thank you.
You are very welcome
Watching your old vids while sheltering from Corona Virus. Interesting hand techniques while camera focused on work bench.
Very nice and handy tool for finding weak signals and noisy components! I will build one, for sure!
Thanks. What a fantastic addition to the workbench. just what the Dr ordered.
I second that notion. I have bought many books that don't have the depth of knowledge and insight given in these videos. And book, especially an ebook with links to these videos would sell like hotcakes. Or a DVD with both book and videos for off line.
You're right on time! I have a record player with one channel louder than the other. With this probe I can sniff out the culprit :) I was planning to build a tracer, but this is more elegant.
This guy has the mind abd skills to become a millionaire over night no problem if starts to patient and sail his awsome powerful tools for sure.He dos have a mind of a genius it shows in all his videos.
