I'm still trying to figure out what to do with this channel. Making something with this much animation and synchronized video clips took ages but I'm happy with how it turned out. Please let me know if this is interesting, if it's too much (or too little!) detail, or what sorts of things you might be interested in hearing about from me. Thanks!
The amount of detail was just right. In principle I could design such a circuit myself, but the selection of the actual components and resistor values and so on always takes a lot of time. So I really appreciate that you showed the selection process and gave a reason for why you chose each component. And releasing everything as open source is a great move.
Really well done. Held my attention the whole time, and I think pacing was just right. One of the very few videos where I watched the whole thing without turning on 1.5x speed. Subscribed!

It's my first time on your channel, but you just got yourself a new subscriber! It was a fantastic little project which was really nicely presented, so everything was super clear to understand. Keep it up, man!
I love engineers because theyll legitimately design a whole sensor from scratch to turn the machine on and off instead of just securely mounting the device to something heavy on concrete
@@UnitSe7en That would be trickier in software and my microcontroller is already busy doing other things. (Someone already covered the pros and cons here: forums.kinograph.cc/t/shakefinder-a-vibration-sensor-for-stop-motion-scanners/2761/7 ) The solution in the video gives exactly the signal I want plus it was fun to build and I learned a lot.
It looks like a good project and an efficient solution that had a high chance of success. The other option that comes to mind is vibration dampening methods, but those could be tricky for the type of system you're using.
Nothing has been explained here. He just gave you all the information in order to do particular thing, unlike college, where they teach you how to find this knowledge by yourself.
The weight, the platform, the knobs, the LED and the proper connectors.The attention to doing things properly is really amazing. I think this detector alone could be a standalone part/product.
I literally never write comments but you deserve some praise, I watched through the ENTIRE thing and you made all of your points so abundantly clear it was INSANE. I was in shock when I scrolled down to see, what, 4 comments and 1k subscribers? I wish you the best! Please, more little easily integrable projects like this
Being fresh from all those electronics class and watch a video that covers all these subjects feel like a joy to see them in practice in such a simple and problem solving way.
Honest to god, this video has gave me back the courage to continue my studies as an EE. Really amazing video, please keep up the good work, RUclips needs more channels like this!
As an engineering student, I loved seeing the whole process of planning, building, and solving problems that come up along the way. You've gained another subscriber!
For a channel with only 5 videos, your production quality and cadence were great. It feels like the result of many years of experience producing educational content. Keep up the good work and best of luck to you!
GREAT VIDEO!!! When I saw the title, my first thought was, He's gonna use an accelerometer, secondly, a piezo device. The video was of MUCH higher quality than I expected...I related to it instantly from decades of design and PCB-making. The video had much more value, in addition to design of a device. THANKS MUCH!!!....thumbs up and a sub. --dalE
This is one of the best made DIY electronics videos I have seen. Dude, you have got the talent for videos like this. The amount of information was not too much to get boring yet enough to keep me interested and watching. You have found a good balance - great video! Keep doing these type of videos and you WILL grow big.
I work as a full time EE and I LOVE this so much. You solve the problem in a real a straightforward way while reminding us we have to use real world parts that do real world things. Can’t wait for more content!
As someone who is studying electrical engineering (first year) this video was sooo incredibly fun and interesting to watch. It's really satisfying to see the whole process from the idea to the finished product. And I love the intuitive problem-solution based approach to explaining the electronics! Thanks a lot!
This is probably the best electronics video I've ever seen. As a student in electronic engineering it always give me so much anxiety picking parts, the part where you explain how to select an OP Amp is outstanding!
This video is a masterclass in engineering education. Your pinned comment mentions that the animations and synchronized video clips took a while, but I think it was absolutely worth it. Seeing the signal conditioning happening live over 4 scope traces synced with the video really drove home the principles you explained. Awesome video!
Please, more of this - Embedded systems (hardware especially) needs more love, both in the field- as well as at home ;) Was a sweet watch, signed myself up for more. Thank you from NLD - Jr. embedded systems engineer
Seeing the actual electric signals and all the circuit diagrams make it so much interesting and cool to watch. Please make more of these types of videos.
The amount of followers and subs does not make justice to this channel's quality, nor the engineering behind it. Simply put: Brilliant! Writing to hopefully bump something in the algorythm.
You did an amazing job explaining each step of the process of designing and problem solving. You must be a teacher. I particularly liked the diagram in the upper right that kept growing as you addressed each incremental challenge. Great job! I would watch more.
Great video format, seeing the thought process behind circuit design is always enjoyable and good editing made it that much better. It also makes it easy to comment about where I'd use a different approach, which is at 7:30 - if the problem is that your signal goes below ground by a bit too much, just shift it - still have the op amp's Vee connected to your power ground, but add a forward biased diode between "signal ground" and real ground, use that for everything up to and including the op amp - piezo, resistor, two diodes, cap, and potentiometer (leave the digital part connected to real ground). A resistor is also needed to bias that offset diode, from the "signal ground" to Vcc, and maybe a capacitor across the diode for decoupling, so three additional components in total. Again, it's just a different approach, not strictly better - you trade off the lower component count of your solution for the ability to use a jellybean op amp. I see that someone in the comments already suggested biasing the piezo to half-rail using a buffered resistor divider, but not only do you need a dual op amp then, your zero vibration output level is also Vcc/2, which the SN74LVC1G123 won't really consider a proper logic low, nor should it. With my solution it's around 0.6V, well within the allowable range (0.8V for 3.0V < Vcc < 3.6V and 0.3*Vcc for 4.5V < Vcc < 5.5V). Again, great video, I subscribed without a second thought!
This is a fantastic and well-thought-out project. I like that you explained your whole thought process instead of dumping SMD parts on board without explaining why, as most electronic channels do. This was really refreshing. Please keep making more of these!
this is a really nice project and a really nice circuit. I have one thing to add if one wanted both the negative and positive peaks of the piezo you could ac couple it into the opamp with a series capacitor and two resistors going to positive and ground rails to dc bias the signal. As you said though not super necessary for this project but it would allow a wider selection of opamps.
I'm absolutely in love with how precise and compact everything you did was, I've got literally no experience with anything you were doing here and I was able to understand every word.
As someone who's getting into circuit / PCB design in the past half a year, I appreciate this video so much! You rarely see someone explain the real world problems you encountered or anticipated AND their solutions with such clarity. Thank you!
Only 3k subs? I thought I was watching like a 400k channel. This is a really good, very entertaining, high-quality video. It really shows you've put a lot of effort into it. You got a new sub for sure and I'm looking forward for more.
As a former drum scanner operator from the 90’s, we faced exactly the same problems. The solution from our supplier was to place it on a concrete floor 100+ feet away from a busy road. So I would move that setup into the garage or the basement. You should see a huge difference if not completely illuminating any vibrations.
This is probably the better answer. I was hoping to make a nice, little desktop machine (and this sensor gets it most of the way there at the expense of making it slower), but if I were serious about throughput, your idea is a good one.
this is super awesome. ive always wanted to see the electrical design process and the transformation from ideal to real world, this explains everything very succinctly.
This is an excellent video about that cool little circuit you designed! Very nice to see the design process from an idea to a finished board! Would also be cool to learn more about your film scanner!
I don't have a need for one of these, but there are a few bits you used that will help me out with a hardware design. Thank you! Also, I really like how cleanly this came out, very nice design.
Absolutely great. I took a circuits course and this gives me a very good example of putting an actual component together. Great video as well. Very concise. Thanks.
To avoid the op amp issues, I’d have tied the piezo to Vcc/2 instead of ground. Use a dual op-amp IC and you get to buffer a 50/50 voltage divider for free with your spare op-amp. Thanks to the signal being nowhere near the rails, you could get away with a non-rrio op-amp like an LM358, though having a wider output range would be handy. Being able to use 3.3V on all your parts would also be pretty handy. As for the 555, I believe you can make both conventional and retriggerable monostable circuits, depending on whether you use the trigger/threshold pins, or whether you use reset as the input instead. Putting a Schmitt buffer between the amplifier and the latch might be a nice feature, that’s also something you can make with a spare op-amp if it can handle being used with positive feedback.
I'm 1.5 years deep into my Electrical Engineering Bachelor's and this video has given me a more intuitive understanding of how circuit components work than any of my courses lol
Maybe use a Schottky diode for clipping the reverse voltage? For detecting the pulse, use the Arduino interrupt, it comes in handy. It interrupts anywhere the program is executing without disrupting program flow, could save a flag that a vibration occurred, then the program runs until code checks and clears the flag. You could establish time limits, then output if vibration detected in those limits.
The Schottky diode is a good idea. That opens up the choice of op-amp quite a bit. And I agree that an interrupt (with a single volatile bool assignment in the ISR) is definitely the way to go. The sample code in the GitHub repo shows how to use it in the clear-the-flag/do-a-thing/check-the-flag way you described. That way you can be sure you didn't miss any events.
As a vibration engineer who relies on piezoelectric accelerometers while knowing nothing about electronics, seeing what's involved in making the black box people call "signal conditioning" is really educational! Thanks!
this was an amazing video! thanks for your time and diligence. ive never seen how SMD's are solder to board in a DIY way so that clip of that was awesome and a great teaching moment
It's inspiring to see such creativity in problem-solving, opting to craft a unique solution rather than relying on off-the-shelf components like accelerometers. Subscription earned.
What a video. I genuinely wish this was part of every circuits class. Turning theory into practice and in such an easy to understand format. Wow. What a great video. I'm definitely sharing this!
I was just about to go to bed when youtube recommended this video, I was just gonna watch the start to see what it was about but the excellent structure, narration and production quality had me glued me to the screen through to the end. Great job, earned a subscribe
I saw someone else state that they rarely leave comments. Ditto, here too! You need to become a RUclipsr. Your videos are exceptional. This was the first video I watched. Than the one on Unreal STL's. I had no idea that was possible. When I was earning my Amateur Extra Ham Radio License, videos like this would have helped a lot. Even the color pallet you used to illustrate the electrical diagram was great. My mom has a box of 8mm film reels. I've been scanning the old slide projector slides currently. Next are the 8mm films. This will definitely be added to my scanner build. I don't have the kids problem...yet :) but, I live in the high mountains of Colorado, and the wind blows all the time causing the entire house to shake from the strong guests. Definitely going to need this. Great job. Looking forward to more of your videos!
The best videos spark ideas and understanding beyond what the video is about, and after this one my head is buzzing with possibilities. Amazing stuff! 👍🐻
That’s brilliant, very well explained. I have used these sensors before to detect an air gun pellet hitting a target. Think I used resistors to try and limit the peak. Love the way you did this , I will be using some of this as it’s very useful thank you for posting.
This video is incredibly well made and you very skillfully pieced together the process and kept me hopelessly engaged throughout the video! Thank you for the content and I hope to see more videos from you in the future!
This was fascinating! As someone studying this subject in college I love to see the flexibility all this knowledge gives you to truly create from scratch a solution to a problem you can call your own
This video was easy to follow despite never touching circuits in my life really hope you continue this channel. Glad subscribing because of that stl file conversion video has paid off
Watching the table shake made go back 15 years. making an mpeg from jpegs, with focus stacking for each frame. I built a stepper driven microscope stage and software for a PIC , and finally made "animation focus stacking Blue Bottle Calliphora Fly" . First setup in an attic, the first days shots were awful, blurry but only occasionally, night shots were better but still occcasionally blurred. Moved to the cellar and an order of magnitide difference where now the DSLR shutter was vissible. in the end had a shutter delay then flashed an led, as i had light conterol in the cellar. but now we have st vibration sensors with 70KHz BW or HX711 with a strain gauge or a long beam siezmometer,
AC coupling the input would prevent the signal from going below ground here. In your situation it seems ok as you indicated you didn't want any DC voltages anyway
I had a family member doing old film scanning recently and this is exactly what they needed! Love the walk through of the design process and it looks like it turned out great
Nice video, loved this style. One little tip I like to do is to put a set of resistor pads in parallel with my potentiometer. That way I can use the potentiometer to get things dialed in at the setting I like, then I can swap it out for fixed resistors so the knob can't get jostled out of place.
very interesting video. I've always wondered how people designed circuits and seeing the circuit being built up step by step with each component's function explained was really cool.
Realy great Video! I love the animation and the narration style a lot. And I love the internet for giving creators the opportunity to share such videos.
ya hey man just wanted to say this is epic! I'd love to be able to come up with something like this! To be honest, I never even considered that this is a potential problem that needed solving but your solution is so elegant that it looks like something one could spend lots of money on developing! I'm so grateful you shared this development with the world and hope to see you continue to produce cool stuff like this!
If you use an inverting amplifier circuit (op amp based), you don't have to worry about the input going below ground. It's fed to the inverting input via a resistor, which forms part of the gain calculation and limits the current to that pin. The inverting input acts as a virtual ground, in that sort of circuit so all you have to worry about is the current going into or out of that pin.
As a software engineer, I would have opted for the software approach: put something like a little square of white paper in the corner with a smaller black square inked inside of it. Make sure the paper is outside the margins of the film, but position the camera such that it still shows up in the shot. Then, each time your setup snaps a pic, since the square is always in the same spot, look at those pixels, and determine if the edges where the black square transitions to the white paper are sharp and crisp. Maybe some kind of convolutional filter like Sobel can be used to extract edges, and then all the white pixels above a certain threshold value can be added up as a "sharpness score". If the score isn't high enough, then you can safely assume the photo is blurry, and needs to be retaken. Perhaps this is my own bias, that I fear the hardware more than the software.
I agree with everyone else. I watch a ton of making channels, lots of electronics ones and I left this video feeling just plain good. It all made sense it was satisfying and it worked well, really top tier work. Can't wait for the bell to ring

Very well explained...
This design can help me to realize a MIDI trigger that I had in mind.
This video is incredibly well made and you very skillfully pieced together the process and kept me hopelessly engaged throughout the video! Thank you for the content and I hope to see more videos from you in the future!
This was fascinating! As someone studying this subject in college I love to see the flexibility all this knowledge gives you to truly create from scratch a solution to a problem you can call your own
Wow, I learned so much from this video. Thank you for posting!
This video was easy to follow despite never touching circuits in my life really hope you continue this channel. Glad subscribing because of that stl file conversion video has paid off
Watching the table shake made go back 15 years. making an mpeg from jpegs, with focus stacking for each frame. I built a stepper driven microscope stage and software for a PIC , and finally made "animation focus stacking Blue Bottle Calliphora Fly" . First setup in an attic, the first days shots were awful, blurry but only occasionally, night shots were better but still occcasionally blurred. Moved to the cellar and an order of magnitide difference where now the DSLR shutter was vissible. in the end had a shutter delay then flashed an led, as i had light conterol in the cellar. but now we have st vibration sensors with 70KHz BW or HX711 with a strain gauge or a long beam siezmometer,
Awesome video, clean concise walkthrough of all challenges,ideas.
Great video, love it when planning and engineering comes together to solve a real-world problem :D subscribed!
Hey Nicholas! Amazing work! This is the first video I have I seen of yours and learned a lot from this.
The final product is beautiful!
AC coupling the input would prevent the signal from going below ground here. In your situation it seems ok as you indicated you didn't want any DC voltages anyway
in university we only had until the 555 circuit, what a great design!
nice presentation-very thorough-I think I may build one of these just as a novelty on my desk
That was superb! Well explained and enjoyable
I had a family member doing old film scanning recently and this is exactly what they needed! Love the walk through of the design process and it looks like it turned out great
Fascinating video! I hope you'll continue making them.
First video of yours I've seen, and you earned yourself an immediate sub, sir.
Nice video, loved this style.
One little tip I like to do is to put a set of resistor pads in parallel with my potentiometer. That way I can use the potentiometer to get things dialed in at the setting I like, then I can swap it out for fixed resistors so the knob can't get jostled out of place.
I like that. I don't think I've heard of that trick before, but it's a good one. Thanks!
I was thinking of a project like this, the last ones i made were for analog feedback ages ago so I appreciate the digital perspective.
very interesting video. I've always wondered how people designed circuits and seeing the circuit being built up step by step with each component's function explained was really cool.
Realy great Video!
I love the animation and the narration style a lot.
And I love the internet for giving creators the opportunity to share such videos.
Awesome video, would love to see more like this.
Video on the machine itself. Looks like an amazing project!!!
ya hey man just wanted to say this is epic! I'd love to be able to come up with something like this! To be honest, I never even considered that this is a potential problem that needed solving but your solution is so elegant that it looks like something one could spend lots of money on developing! I'm so grateful you shared this development with the world and hope to see you continue to produce cool stuff like this!
If you use an inverting amplifier circuit (op amp based), you don't have to worry about the input going below ground. It's fed to the inverting input via a resistor, which forms part of the gain calculation and limits the current to that pin. The inverting input acts as a virtual ground, in that sort of circuit so all you have to worry about is the current going into or out of that pin.
This video is amazing. So good to see you come back to this channel. Looking forward to more in the future
As a software engineer, I would have opted for the software approach: put something like a little square of white paper in the corner with a smaller black square inked inside of it. Make sure the paper is outside the margins of the film, but position the camera such that it still shows up in the shot. Then, each time your setup snaps a pic, since the square is always in the same spot, look at those pixels, and determine if the edges where the black square transitions to the white paper are sharp and crisp. Maybe some kind of convolutional filter like Sobel can be used to extract edges, and then all the white pixels above a certain threshold value can be added up as a "sharpness score". If the score isn't high enough, then you can safely assume the photo is blurry, and needs to be retaken.
Perhaps this is my own bias, that I fear the hardware more than the software.
Adding test points... going to use this on every test board moving forward
This is a really great video - you’ve got a gift man. Please share more!
I agree with everyone else. I watch a ton of making channels, lots of electronics ones and I left this video feeling just plain good. It all made sense it was satisfying and it worked well, really top tier work. Can't wait for the bell to ring
This is such a great project, it brought back so many memories from when I was on the analog labs in uni!
I aspire to have your expertise one day, great video.
