Comment of the year.
...but he didn't. He used someone else's code.
What I learned from this channel over the years is that in order to do less work you have to do more work than you originally had to.
because it’s only ever less work for future you never present you
a
It's just converting the work into other work that you like more. In this case he could just suck it up and write them out, or he could make a machine to do, that he not only is much more suited too, but also enjoys it's and allows him to hone his craft.

@@whatadude4841yes but it’s not a person. It’s a perfectly calibrated auto rig
@notnotme1715 you two are pretty funny
I'm surprised pen pressure on the paper wasn't more of a problem. Seems like the robots perfect line darkness would stand out more.
My guess is they actually talked about how good they were, and what we saw was what we were allowed to hear.
I came here to say this, but in my heart I knew it had already been said
Probably not the most notable thing, especially if you consider if they were actually sent out you’d only see 1 and would have no comparison for the pen pressure,
And repetition is much more noticeable to the brain
@@BossKnightalso ballpoint pens, especially decent quality ones, tend to have little variation in darkness with pressure.
You would be able to see lots of different pressures between each letter. When handwriting, you have to lift up your hand for each letter so you wouldn't be able to use the same pressure on every one
This video is the embodiment of "we do things not because they are easy, but because we thought they were"
and we make necessary concessions when we realize it was a little bit too not-easy

@@thenightjackal8876 yea but budget doesn't change 😭😂
lmao 🤣
🎶WE DO WHAT WE MUST BECAUSE WE CAN! 🎶
Ok, one major tip: natural hand writing is in fact a 3D action not just 2D, meaning that the writer exerts higher and lower pressure vertical to the paper surface as they write, which results in the pen line becoming thinner and thicker at different sections of a letter! Next try to build the Y-axis movement into that robot!!
Brutal
Or the microscopic human skin flakes and grease we leave on the paper while writing?
Yes I thought the handwriting expert would make this point. Maybe the robot does press more in some places?
I was about to suggest the same haha
Not only the pressure of the pen but angle of the pen too (or rather two angles) and the writing speed.

I would like to thank you on behalf of all criminals for giving us starting point of forgery and also explaining us how we might get busted so we could fix this before we go live.
They don’t need forgeries any more. They just steal it out of your bank account online.
I wanted to start a youtube channel where disgruntled industry experts explain how people could hack/cheat/bypass safeguards, if they even exist. It would be called "*IF* I Did It"

It's a cool trap of reverse psychollogy. Yo get so smart and skillful making a machine like this to try to do something illegal, that you end up pursuing a better career in science instead of being a criminal
@@Zal1810yeah like that surgeon who m4rd3red ~300 minors before realizing he can be a doctor
just a tip when using neural networks. In the video, I noticed after every bug you fixed, the editing at least made it look like you spent ~50 hours training the RNN again. Usually, you can use smaller datasets to train the networks and see if the output is slightly acceptable before spending the 2 days training the network with the full dataset.
Bingo
I also notice he didn't plot his training loss / validation loss. It's very important to be able to know if both are decreasing, otherwise you might just be overfitting to noise or something. 😆

I love his wife’s facial expressions. It’s just the look of someone who loves a benign lunatic genius.
Your training process, and failures afterwards remind me of my early days in computers in high school. We "wrote" programs on a paper teletypewriter, using a computer program named BASIC. Each line was numbered, resulting in hundreds or thousands of lines of commands. The we hIt "RUN". and would wait to see what the computer would do. each run resulted in "successive approximations" until we got it to run. That was in 1973! Wow, I thought that those days were over! Great video.
wait... I thought that was how things were done....
Basic is basically programming on root, tough stuff
Yup! lol. PDP-11 in 1976. We had to punch a paper tape to save the program for the next class. Newsprint as I recall. Didn't always work, yah, then you had to retype it.
I have to say, one of the most helpful parts of your video was when you gave up and used code off the internet. It's nice to see others realize that some other people just do things better sometimes and you don't have to re-invent the wheel every single project. Buying a plotter, borrowing code. This is how things move forward. Good luck in your new shop!
That's how science and engineering works. You use what other people have done in the past to create something new.
Anyone have tips on how to do this more? I often feel like I'm spending just as much time figuring out how to integrate or implement their code into mine. I suppose that's just down to the quality of the documentation?
yeah, I started writing a custom library for playing audio files in vanilla JS, and then I thought "wtf am I doing - just find an open source one". And lo and behold, there are like 5 of them.
@@EmersonPeters Be sure of what you need. Once you know what goes in and what goes out you can use other works as a black box. GPT can also help with code integration nowadays.
That is why i share every line of my codes to github... it feels great to see someone uses something you did and turn it into something more useful 😂
My favorite part of this channel is how you show yourself making mistakes, finding the error, and trying again. Over and over and over.
You're inspiring.
As a full time programmer, that "But why!?!?" - "Ooooh..." really made me nod and giggle haha
Lol yea makes me feel fine about my work process 😅
we're not alone 😭
My favourite part is your comment!!!!
Jesus loves you alot trust in His death 4 salvation and be saved from eternal hell
I feel like, in this case, a forensic handwriting expert being able to make a profile for your handwriting bot is a feature, not a bug. After all, you're *not* trying to make 20,000 unique sets of handwriting, you are trying to make *one* set of handwriting that is consistent across 20,000 use instances. And if he sees enough shared characteristics between the different pieces of writing to work out a profile, that means they are identifiable as having been written by the same person (or, I guess, robot). Which means that you succeeded in creating a unique and consistent handwriting style
A very very few people in the world got what it takes to produce videos like this. Technical and theoretical knowledge, a good sense of humor, and video editing skills. this man deserves a medal!
I love the field of Computer Science.
Spending 4 months to create something to do a 3 hour task for me just gives such a huge feeling of accomplishment.
Until a year later when you need to do the task 10,000 times. Or 1M times.
thats how mostly any machine got made.
There's two reasons why investing a lot of time to gain small benefits:
- If you repeat the task, there will come one point where your work amortizes itself
- You probably invest all the time (i.e. 12 hours for 10 minutes faster tasks) at a point where you have it available and you also have fun with it. I've done the same for my collagues with some forms - they may only save a couple of minutes but we all get done faster and have less repetitive tasks since they're done automatically.
in my junior year of hs i had an obsession with writing code to basically make specialized calculators for whatever we were doing in math. definitely spent more time on making those programs than time i would've spent actually doing the work, but it was fun lol
This really gave me a mood boost as a starter CS student
The shot @9:37 has me holding my sides. A $35k robot arm, TWO computers, a big power cabinet, an air compressor, a shop-vac... "But that would be over-engineered!" 😆
funny.
Totally missed that, you are definitely correct.
18k arm
My guy said “But that would be over engineered” 💀 9:33
These animations are amazing! Can’t image how much work went into this video.
You know you're an engineer when you spend hundreds of hours designing and building a custom solution to do a simple menial task
In fainress he actually ended up just using someone else's code on someone else's robot. All he did was feed it paper with a second robot.
@@Electric999999 he also handed the robot a pen haha. Seriously though he did engineer the trays to hold the cards, the system for picking them up and dropping them, the system for holding the cards for the writing bot and integrated those 2 robots together with the code etc. so it's not quite as easy but yeah.
Giving up and using an existing code base is actually very typical of engineers in other jobs too lol.
I feel like I am cut out to be an engineer then, since I have ocd and I have spent hundreds of hours during my free time, to optimize my free time, so I have more free time. No joke.
@@briondalion3696if you are old enough to go university, give it a shot. You can't be a certified engineer without an engineering degree.
I'm a software developer and I have a job and that job often makes me do tasks that take hundreds of hours only for no one to use it.
Honestly I think that having a postcard written by a project you made is way cooler than having one hand written

His job is inventing, " He is an inventor with five patents and 13 pending applications. " -wikipedia
the most educational part of this is when he says, "on the first try, too! that never happens!" I always got discouraged as a kid when I didn't get things on the first try and i gave up. i didn't have any confidence to try again because i always tried my hardest the first time. If my best try wasn't good enough, no further tries seemed like they'd fare any better, so i, being a very reasonable and smart kiddo, concluded i just wasn't very good at that thing.
I love the 13:30 moment of what the article is called xD

I've worked on a ton of machine learning projects over the years and seeing him go through the same process of training a model for a stupid amount of hours, having it not work and then finding one small mistake in the code each time is insanely relatable

That is the basic process of all programming.
@@kellymoses8566 with programming you don’t have to wait 3 days to find out if your changes worked?
@@fincottle5534 yea, with ordinary programming you can usually tell almost immediately when something is wrong, but in machine learning you cant really tell until you've given the algorithm enough time to learn
I have to say this channel is really one that makes me feel like i did as a kid when I think about Engineering. Thank You for that.
I was hoping you would go more into the actual mechanics of penmanship since the ML and graphical/font side of this is likely been researched quite a bit. As a dynamic font the results were great but still the giveaway to me was the super consistent perpendicular constant pressure strokes. Wouldve been cool to see u tackle variable stroke tilt, speed, presssure mechanics. The tapered stroke you get from the flick of a pen is completely absent.
Your video and editing skills are coming such a long way.

Absolutely love how succinctly you managed to sum up the experience of learning machine learning: write code; wait hours/days; find out you made a really dumb mistake; repeat steps until you eventually either ragequit or swallow your pride and decide to see if someone way smarter than you already figured it out (SPOILER ALERT: they did).
Actually I suppose this goes for a lot of things!
To me, the main danger from forgeries is in faking signatures on documents. I'll bet the pressure points of my signature are recognizable to an expert, (from their depth and spacing on the paper, not necessarily from ink flow), no matter how sloppily I sign it. I sincerely hope you don't explore copying signatures too deeply!
I've watched a number of your videos. You tackle some amazingly difficult projects, and with a lot of humor, too! I love the way your wife keeps you humble. I'm sometimes reminded of old "Honeymooners" episodes, where Alice Kramden raises an eyebrow at Ralph's latest "crazy scheme." It's powerful stuff, well engineered, and your videos are nicely produced, too.

I program similar robots for CNC production. One that that made me curious was to the paper getting picked up problem. He built those platforms with the springs which is near but those robots have the ability to compensate for those sorts of things.
We have pallets that we place parts on and we can teach the first point on the pallet and the robot auto compensates and grabs each part and moves up and down the pallets automatically.
@@specialsause949 Same here, programming for cnc tending. The function I used was called servo float or soft servo. And the end effector would stop with a programmed force.

@@SianaGearz I must thank my coder on behalf of you to make me as human like as possible
I kept all my school documents. And that is a lot of hand writing. I wanted to scan it all, and use OCR with a temporal variable. That way I can see handwriting improve over time. And also train a model to write whole words, not just single letters.
But scanning two full boxes of documents takes over a week. And I don't have any scanner.
I feel like a vector sequence model instead of a pixel model would generalize better.

i am an old school sign painter...you have discovered something we old school sign painters have known for hundreds of years...we call it KERNING. kerning is the spacing in letters of a word that changes depending on the letters surrounding it...this was very apparent in the early 1980s when the first computer designing signmaking machines were built..they couldnt "program" in the human spacing/variation "errors" and characterizations that humans added to handwriting depending on or based on "it just looks right" for a particular front style that didnt look right for another. in the 1980 computer memory was so limited and slow that you couldnt have enough to program all the handwriting variances... today you can and it helps than no one writes in "cursive" anymore

Meme daddy???
let me get a shout out
@@CorruptOcean why
personally, i think the idea of you putting all of this work into a cool personalized project that can automatically write cards for people is more endearing than just writing a bunch of cards, because like anyone can do that. you put your own personal touch on the idea and that makes it special.
It's on brand which is why it works
This guy is a literal genius. I have yet to find anyone with the creative AND practical means to have such an amazing end product. Congratulations, you're a badass.
Great idea masterly executed
Really man,SO COOL!!This is really interesting and entertaining.Thank you!
One of my family member is graphologist. She told me that the pressure you put on each letter with your pen is also examined (showing how much emotion you put on some words)
So if you're only looking at the 2D-shape of your letters, you're missing something.
Oh, I literally just mentioned the same thing before scrolling. 1:11 if you pause and full screen it gives a perfect example of what you are saying.
This definitely could be sorted with a bit of pressure from an actuator on the pen
The interesting part about that he can implement that into the machine with the suction function. By adding the amount of suction to each specific word or letter at least 50% of the words wouldn't have the same pressure due to the change of suction for each words and since the care isn't rigid there would be tiny (I assume only noticeable under investigation) changes. It's a crazy thing he has built
@@bryang2280 Honestly I think you could just have the writing machine itself do it. It already can lift and push down the pen (since that's how it works lol) so I don't see why you couldn't just have it push down when writing certain lines more than others
This was my biggest “tell” of real vs fake. Hard to copy the random pressures and pen scratches made by pens when handwriting something. Like the little tail left behind when finishing a word and lifting the pen at the same time.
So I love the realness of this video. As a fellow scientist I understand when you say “I have no idea what I’m doing” and it’s so true. None of us do we all rely so much on each other to solve our problems and the past achievements of others to move forward. That being said pls upload more even if it’s just updates about current projects or anything else you find interesting.
That is normal? I'm currently doing my bachelors degree and feel like that half of the time.
He's not scientist He's engineer better than a scientist
@@tillthiemann6448 Of course it’s going to feel that way. You wouldn’t learn much if you just kept repeating stuff you knew. Math degrees are not earned by repeating “1+1=2” for 50-60 hours a week for four years.
Malcolm Gladwell suggests 10,000 hours to master a skill: practice, feedback, learn new stuff just outside your comfort zone.
this reminds me of a cartoon from the 2000s called lazy lucy about a girl who hates doing tasks so she comes up with incredibly comedically complicated schemes to make them 'easier'
“Building stuff of dubious utility” is the best tag line ever. So happy to see you back!
I think that 2 possible differences from the normal handwriting are pressure variations and speed variations these 2 can be especially seen with fountain pens. In this case even the angle at which the pen is held changes as the word progresses and this changes line geometry
I had the same thoughts
Ditto, the pen needs variability & pressure feedback
@@EngineerMikeF yeah, it could be even implemented as controlling the pen force instead of controlling pen height, made as a weird closed loop system. Or simply move the pen up and down and have it spring loaded, the force of typical spring should be roughly proportional to the amount it was compressed / extended
Maybe the pen could be connected to a spring so as it moved there would be a slight wobble and / or a random offset could be applied each point making up a letter. Would also like to see some deliberate spelling/ writing mistakes to be more human like
Ink smear. Near impossible to have a machine replicate this.
Love the chemistry between you two.
The amount of effort this took is incredible!

@@nohmers18 that's because it's not for an audience of specialists so obviously to make it accessible to everyone, you will dumb it down and if you don't like it well... I don't think you should expect that of this channel because it's not the main goal to go in depth about the smallest things.
Omg, your segment on debugging machine learning programs was so depressingly accurate. Training something for hours, checking the predictions, and getting complete nonsense. Just to learn that you did something dumb somewhere (like maybe you used a '-' instead of a '+' somewhere). Then train again, and repeat until either you get it working, or you give up on life.
Though of note: it is important to monitor NN training. Looking at loss, accuracy, and any other metric while you are training. Also training on smaller datasets first to iron out bugs so that you don't waste as much time.
Her "leaded" reply is highly underappreciated
Reminds me of the old-school drafting printer we had in school, that handled huge sheets of paper. It was like this, but at least 5 or 6 times larger.
It had an arm and a bunch of different coloured pens, and drew each line one-by-one. It would go fast, fast, slow. Stop in weird places and continue in other weird places. Was a lot of fun to watch.
This guy is the epitome of answering questions nobody asked but wished they did
Facts lol
This would’ve been so useful in elementary school for me with those notice of low scores slips I got
You should send these to "handwriting experts" who think they can get insights into a persons personality or backstory from their handwritting.
You'd want to ridicule them?
Anyone writing each letter individually and not joining them up is sure to be a psychopath
@@dariusftw3378 Lol I am the type of person to handwrite everything IN CAPITAL LETTERS.
@@getmeoutofsanfrancisco9917 must take you forever to get anything done lol
@@dariusftw3378 At school I had absolutely horrible handwriting when I was joining each letter up so I started to write individually and am now trying to unlearn 10 years of writing that way because it looks kinda unprofessional.
15:30 I love how it just writes “no”, as if saying, “I’m done”.
I was looking for his onshape for a while!
I work at a print company, all these designs are super similar to tons of the machines i work with as a folder and booklet maker. The feeder on my Horizon buckle folder has a similar suction cup design to pick up sheets quickly. You did your homework, and built a sweet machine. Props to you brother
That TechCrunch article at 13:20 had me dying. Beautifully done. Nice work overall, and what a cool project! Thanks for sharing!
I love those details too !
In the '90's I had a plotter, mixed half a dozen handwriting fonts, and tweaked the baseline shift, and baseline tilt to make writing indistinguishable from... plotted text.
This is very impressive even if you didn't write your own code. It takes me so much work to write, edit, voiceover a quality video, but this is on another level.
Honestly this makes the notes even more charming. Knowing the story behind the cards makes them that much cooler
12:40 The way you explained a loss function for a neural network architecture is just flawless. Great job mate! That is Josh Starmer level explaining right here.
From now on I will always call the loss "garbageosity"!
I like the little camera bit in 13:25 that was left in the final edit
I had a question about what he said though, when you calculate the slope of the error function, it's dimensionality should be based on the 'number of knobs' in the last layer, so when you move in the direction needed to minimize error, aren't you turning all of those knobs simultaneously (and thus, all the previous knobs roughly simultaneously as well since you propogate that change back through the network?)
He is so amazing at explaining what is happening to people that have no idea. respect.
Your resourcefulness is frightening
I started a robotics degree because of you, thanks for changing my life for the better!
@@test1122lol literally noone asked for your pathetic opinion
Keep going! We need more STEM majors!
That's a good field, especially if you're willing to get your hands dirty. As time goes on automation will only increase, and therefore the number of people needed to babysit, clean, repair, and program those machines will increase.
Fun fact about new technology: It ain't reliable, and is in constant need of refinement and maintenance.
@@test1122lol what
@@isthatbraised I'm talking about living in a 9-5 slave lifestyle, compared to being financially free doing what you want, when you want, with who you want
Is anyone really going to talk about how the wife managed to correctly decipher every fake card despite not being completely obvious and apart manage to see the ploptwist of the last 4 letters? If she is not a detective then she is not in the right job
Or what about how much Meth she has been smoking.
Simp. Anyone with half a brain could tell the forgeries.
Glad I wasn’t the only one that had that on their mind. She definitely wife goals
