  • What's inside this "active stylus" and how does it work? No spoilers ;)
    Thanks to my patrons for making these videos possible.

    Thank you for creating more UA-cam videos. I'm not into the whole watching a stream thing so this is a godsend for such good content.

    You are actually insane and I want to be that insane some day. Especially the overhead catcam part.

    My cat bit a hole in my cable, is that it? Yes. Deep sigh.

    I can't remember the last time someone inspired me as much as you do. Thank you for everything you do; you have my eyes and signal boost.

    most of these capacitive sensors (screens) keep track of the contact area (probably how much of the sensing grid is changed) which helps it reject things that are too thin (probably false positives?) and too thick (probably your palm)
    in android that data can be shown live under the developer settings

    I've used a baby carrot as a stylus in a pinch.
    It works surprisingly well.

    hey, this was a good video, regarding the stylus. I don't understand everything you were talking about, but it was super interesting.

  • @jaro6985

    Super interesting. Its rare to see SRFs in low cost parts, but if this thing is putting out ~60V, it makes sense to protect the output if it happened to short. Wonder if its enough to get a tingle if you touch the end, maybe not quite.

    My active capacitive pen had its tip screwed on, looked exactly like yours. I presume screw it on is cheaper that applying glue, for the tip at least. Thanks for the video!

    Thank you for this video , can you do similar analysis on apple pencil and explain that thing works with so much accuracies

    Can we get a more in depth look at the tuco flyer? I know you've put out the videos and documentation for the gimbal itself but I'm interested to see the full mechnanics of it - looks like it has quite a large area of motion and I'm curious as to what you did to achieve that
    edit: nevermind, looks like my missing piece was the winch bot

    what are the cameras being used at the beginning? it seems like they're robotic/on a rail?

    So good! VERY interesting, I have a Perixx tablet, it had a battery powered stylus, lost the stylus... too stingy to throw the tablet away. I wonder if this might work with the Perixx? Awesome investigation!

    I love this. I have a pen like this (cheap no name) and did the same thing. except I don't have an oscilloscope :(
    wish you lived in Toronto :( Have this other board that I'm trying to figure out 1 mystery missing component (I think inductor).. manufacture quoted my brother $500 for a repair. I'm convinced it's only a 50 cent part on AliExpress tho.

    Unfortunately it seems like this model isn't available. I've been looking for a decent pen like this and then disassembling it to re-package into a shorter unit. Battery would need to be smaller though

    Awfully soldered smd components! Do you have a video on the robotic cat tracking? Is Opencv used in shape tracking? Too many questions 😁.

    i used to wonder how hard it'd be to modify styluses to work with different tablets, like modifying an intuos 2 stylus to work on an intuos 4 or something like that

    I wish it wasent so hard meeting other introverts. Especially ones interested in the same shit and as chill as i am.. i thought i got lucky and found someone who could spend our time together but she out of nowhere started doing heroin and kept me from finding out she was doing it until i found her lifeless and gone with the thing hanging out of her arm.. really killed something in me also.. had no clue. Only realized that she all the sudden started asking really dumb questions which was unlike her. Last thing she said to me was “what does the moisture adjustment do inside the fridge drawers?” Lol. I just asked her if she was tired or feeling ok.. then had to go to work.. telling her mother was the hardest thing ive ever had to do because her other daughter, the younger sister, drowned in a freak accident in a hotel pool 7 years earlier and was the only family she had left. They were best friends and neither had a clue about the drugs..
    So thats my story.. if anybody reads it or cares.. lol. Sorry.. im one lonely ass motherfucker tho.. ¯\_( Ⓘ︠ Ĺ̯ ︡Ⓘ)_/¯

    Do you not have isopropyl alcohol? It makes most of the glues melt apart

      i don't think i had anything that would dissolve CA glue, and this was a really inconvenient space to use any kind of adhesive remover on. I'd definitely give some chemicals a try if i did this teardown again.

    • @8Dbaybled8D
      @8Dbaybled8D 3 роки тому

      @@scanlime they make these toothpicks with cotton on (like q-tips but pointier) which have been a godsend during any cleaning of electronics, well worth a try as it would've injected the right amount of iso to lessen the glue's purchase
