Special thanks to Ron Morris for taking the time to analyze a bunch of writing samples that I sent him. I got in touch with him after getting his textbook to learn more about the subject: https://www.amazon.com/dp/0124096026

This robot uses a tormach ZA6 to tend the writing robot: https://tormach.com/machines/robots.html

    Thanks to the generous support of patrons I’ve been able to move my shop multiple times with less fear of going bankrupt. I’ve been wanting to send out something cool as a way of saying thank you, which led to the creation of this robot. If you’re interested in helping to support these projects you can join the patreon at https://patreon.com/stuffmadehere. I’m not sure how long this robot will work, but I’ll be sending out postcards to new patrons until its inevitable demise…

    I cant believe you managed to create machine learning code for doctors handwriting on the first try

  3. Kenneth Caldwell says:

    Honestly I think that having a postcard written by a project you made is way cooler than having one hand written

    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.

    • Jordan says:

      ​@Till Thiemann It’s pretty important to have others to discuss with. Doing it yourself is pretty damn tough! You never know when a classmate will understand something and can easily explain to you, and vice versa. When I was doing my bachelor’s, me and 2 others would do the homework in the library just about every night. Class was insanely hard but because of it we all got A’s. Highly recommend working with others (but don’t cheat pls, hurts yourself for the harder classes) (engineering/physics was the classes we would study together)

      He’s not scientist He’s engineer better than a scientist

    I love that you always show your wife laughing so we know it’s just a skit and she’s not actually emotionless 😂

  6. Homme Banal says:

    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.

    • John Graham says:

      This definitely could be sorted with a bit of pressure from an actuator on the pen

    • Bryan G says:

      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

    • Orange Nostril says:

      @Bryan G 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

    • mikess308 says:

      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.

    I was heartbroken to see the mural of your wife covered up, it was absolutely beautiful. This shop definitely needs another creative tribute.

  8. Misael Capria says:

    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.

    • Casper The Ghost says:

      because it’s only ever less work for future you never present you

    • Seth Harrington says:

      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.

      one time investment basically

    Lets give your wife an award, shes so great on camera an know just how to come at you so that we smile endlessly

    I will never get over how hilarious you two are when youre both on screen. You seem just perfect for each other, its like when the deadpan delivery comes from you both the sum is greater than the parts and its 100 times funnier.
