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.
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
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.
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, UA-cam 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!
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.
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
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 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!
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!
I love how you actually highlight, color, and label the various parts of the circuits to explain easily why they exist in teh circuit at all. this is the superior method of teaching circuits compared to anything I've seen thus far. Please keep doing this. It will prove incredibly valuable to people learning.
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.
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
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!
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.
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!
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!
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.
How neat ! I made a vibration sensor also, but not nearly as sensitive as yours. It is just a 3 cm bare wire in parallel with a narrow strip of copper board, with the wire running approximately 0.5 cm away from the board. It works very nicely with a PIC microcontroller being woken from sleep with the change on the input pin. Thank you for showing us your 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.
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.
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.
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.
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.
Amazing sensitivity outta bone stock components, nice. I also quickly discovered how many ways there are to solve the same problem! The 'beyond negative' rail problem could have been avoided by simply having the non-signal leg of the piezo resting on a vcc-to-gnd resistive divider, essentially lifting it 1V or so above gnd, that would enable more op-amps to be used, you will also approach the middle of the op-amp work range for better everything regarding op-amp'ery. Still it was a great experience following your train of thoughts.
Hey Nicholas! First - thank you, thank you, thank you for such am unbelievably detailed and thought-out video. I went back over this video three times, and I can't believe how much information you packed into less than a couple dozen minutes. Then I went back through your other four, and I was amazed at how succinct and effective you were at explaining each of your projects. You remind me of another UA-camr I found 8 years ago, who uplifted my entire career path, just by explaining my interests in such an effective manner. Second - you mention "I'm still trying to figure out what to do with this channel." As someone who is walking down the learning path of becoming a "maker", I can say that you are exactly the kind of person who I would like to learn from. Your videos every couple of years will be amazing to learn from, but I feel that one really fruitful path would be to get yourself and your thoughts out there at a more regular cadence. Even if it's just a video of your thoughts about how to tackle a project, I'm sure every one of your viewers would love to learn from how you think and how you tackle the work that you do. Just a few video topics that I would love and that come to mind are: "Here is my current electronics & 3D printing workshop, and here are the things that I am tinkering with", "Here is a face-to-face chat / Q&A of this part of my project (e.x. why you scanned each film frame with RGB, how you set up your film pulley system, the work you did on the camera aperture devices, how you set up your extruded aluminum framing, etc.)", "Here are some things I've realized could be done, but I that I don't have time to complete." I feel that just by hearing more of your day-to-day thought process, a lot of people like me can learn more in their path towards understanding 3D printing and electronics. Third - thank you, again. You have exactly the kind of experience and teaching capacity that can help others learn well. I really, really appreciate all the work that you put into each and every one of your videos.
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
Nice video mate. This was very interesting - the breakdown of the full engineering process and explaining each part of the circuit as it popped into relevance was a great learning experience.
I don't comment on videos often, but this one deserves the praise! Thank you for the thorough explanations at every step. One of the best project videos I've seen in a while. Really hope to see more from you in the future.
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.
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.
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
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!
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
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!
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!
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! 👍🐻
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.
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!
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.
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
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
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.
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.
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.
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
Great video. Extremely informative and I love the way you walked us through your thought process when designing the circuit. Take my subscribe, You've earned it sir.
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

Man... I don't want to scan all of this in my basement. This machine is soo slow! 🤣
The real value here is this beautiful educational content@@NicholasPiegdon
Or he could have just used an off-the-shelf MEMS package(!)

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.
Now this is a real-world problem solving with better explanation than a college

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
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!
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
Just enough motivation to start my own engineering channel, great!
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!
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!
This is an incredible video and you made the design process really clear and accessible.
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! 👍🐻
First video of yours I've seen, and you earned yourself an immediate sub, sir.
Can I give you a high five? There's so much here that I'm learning and still trying to unpack!
Man, I feel like you would be a great professor
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 went immediately to the comments to check if someone suggested the approach with the Schmitt buffer. It just solves it much more eloquently
Love the step through of the engineering process
Awesome video, clean concise walkthrough of all challenges,ideas.
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!
Hey Nicholas! Amazing work! This is the first video I have I seen of yours and learned a lot from this.
Great video, love it when planning and engineering comes together to solve a real-world problem :D subscribed!
Awesome video! Wish you can continue to share your curent project to the world!
You have an incredible talent for clearly presenting information
Wow this was exceptionally well done! Awesome job putting this together. Your content is great.
This is an absolutely perfect example of top-tier educational videomaking. Thanks for sharing!
Wow, I learned so much from this video. Thank you for posting!
Very well explained...
This design can help me to realize a MIDI trigger that I had in mind.
The final product is beautiful!
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.
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
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, how simple and self-evident -- once you build it on camera! Great video. Subbed.
Wow, the quality of this video is phenomenal! Everything was explained perfectly. Definitely curious what this channel could bring next
This made electronics look less like magic and more like something I could do myself. I need to learn more about the specifics on how this works now!
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.
That was superb! Well explained and enjoyable
Fascinating video! I hope you'll continue making them.
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.
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.
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
This is a really great video - you’ve got a gift man. Please share more!
As an electronic engineering student Im so excited to know about the existence of this channel
Great video. Extremely informative and I love the way you walked us through your thought process when designing the circuit. Take my subscribe, You've earned it sir.
This is incredible. I loved every minute of this video.
Very nicely done! And, thank you for sharing the design with us 😊
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 video is amazing. So good to see you come back to this channel. Looking forward to more in the future
