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.
I rarely comment, but I owe you a thank you on this, you definitely got that pleasant charismatic way of describing details!
I am a busy person and I was just going to skip through the video, but instead ended up watching it all. You must be doing something right.
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
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(!)
@@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.
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.
Now this is a real-world problem solving with better explanation than a college
so true
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
+1 on this. I'm an electrical engineering student. None of my professors have been so clear and intuitive.
I thought the same thing, great video quality, clear walkthough, i thought it must be a bigger chanel
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.
As an electrical engineer, this video does a tremendous job showing off various aspects of the craft in an easy to follow format. Amazing work!
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!
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, TH-cam needs more channels like this!
Put the whole contraption on a spring uncoupling table.
A heavy slab floating over the table on some soft springs
And on a concrete floor
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.

I watch a lot of videos of people making cool projects, but I rarely feel the need to comment. This was awesome start to finish.
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!
As someone studing all this electronic problem and component, this made my day
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.
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!
As an electronic engineering student Im so excited to know about the existence of this channel
Like everyone is saying, this is a standout video. Real Ben Eater vibes hahaha. Continue educating man, this is terrific
He is to electronics what Ben Eater is to Computer Science
This is some proper stuff right here
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.
I am a student studying electronics, this video really helpful. Please, make more videos like this
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.
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!
Best electronics video I saw after the Ben Eater's 👍, the logical reasoning and the thought process goes into the breadboard is simply gorgeous.
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.
Can I give you a high five? There's so much here that I'm learning and still trying to unpack!
you make circuit design sound way less scary, the video is really good, thanks ! Now I want the desk toy...
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!
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.
yes! we have the technology to do these things EASILY yet we stick to old slides with screenshots from textbooks.
Your process and video are so cool!
Incredible video! Please continue!
Awesome video, clean concise walkthrough of all challenges,ideas.
This is really cool, hope to see more stuff from you
extremely well presented! can't wait for your next project
I like your editing and storytelling style. Keep it coming man!
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! 👍🐻
Lovely video. Amazing to see the step by step engineering of this thing, and such an amazing end design! You made an outstanding work!
Such a cleanly made solution, glad it popped up in my feed
Fascinating video! I hope you'll continue making them.
Wow this was exceptionally well done! Awesome job putting this together. Your content is great.
Very well explained...
This design can help me to realize a MIDI trigger that I had in mind.
your explanations are great.
Beautiful project, thanks for sharing it
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!
Seeing the thought process was very inspiring, great content!
I really enjoyed your video! I would gladly watch more videos of yours like this one!
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.
That was superb! Well explained and enjoyable
Loved the way you stepped through your design process. Great work, hope the scans turn out great!
Amazing and very easy to follow vid!
Hope you keep it up!
This is a really great video - you’ve got a gift man. Please share more!
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 video is amazing. So good to see you come back to this channel. Looking forward to more in the future
Awesome video! Wish you can continue to share your curent project to the world!
really well explained and presented
You have an incredible talent for clearly presenting information
Very cool project, and exceptionally clear and interesting explanations!
Wow. Great job on the surface mount photography.
this is one of the best videos on electronics design I've seen
Excellent visuals, well executed and explained. Thank you for this level of production.
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!
Interesting project! I love the way you explained every single decision you made. Knowledge has been shared!
Awesome video! Start to finish.
This is incredible. I loved every minute of this video.
Superb job. Loved this. Excellent video too.
Wow, I learned so much from this video. Thank you for posting!
superb video editing for a channel this size! Keep it up mate!
Everything was top quality, thank you sir
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.
Keep the cool projects coming. You are obviously a very smart guy. The channel will grow!
I aspire to have your expertise one day, great video.
Man, I feel like you would be a great professor
Hey Nicholas! Amazing work! This is the first video I have I seen of yours and learned a lot from this.
This is an incredible video and you made the design process really clear and accessible.
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
Man you would be a great teacher at electronics engineering.
you are not only a good engineer but also a good educator, a pretty rare find :)
This is an absolutely perfect example of top-tier educational videomaking. Thanks for sharing!
You have a great talent for didactics - and a great voice to convey it all. Absolutely bewildering to see only like 3.5k subs...
Wow! This is amazing.
Chefs kiss for the explantion❤❤❤❤
Great video! I am starting a project very soon, where I need to detect when a valve starts to oscillate, and this video gave me some good information about the problems I potentially will run into.
Wow, the quality of this video is phenomenal! Everything was explained perfectly. Definitely curious what this channel could bring next
Thanks for that great video 👍🏻 I would really love to see a more detailed one about your setup to digitize the old films 😍
This is such a great project, it brought back so many memories from when I was on the analog labs in uni!
This is such a cool video! Having a niche problem and showing how it can be solved with basic circuit skills
First video of yours I've seen, and you earned yourself an immediate sub, sir.
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.
Honestly Nicholas, I'm completely in the dark about anything electro engineering or computing related. Yet I enjoyed this video a lot, feels like I might've even learned something. Thanks!
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
Love every single thing about this video.
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.
Video on the machine itself. Looks like an amazing project!!!
awesome work!!!
Very neat project!
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.
INCREDIBLE VIDEO MAN!!!!! Hope to see more in the future :))))
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!
That was so awesome to watch
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.
Great video! I found your method of introducing each hurdle you encountered, describing it, and then working out the solution to be very informative and also a bit inspiring as well. I have subscribed 👍
