I searched for how a graphics tablet works, scrolled through all the review videos and found this which looked like an actual explanation video of the working. Got to say this is the most satisfactory video I watched. The information density in 30 minutes is huge. Definitely subscribed.
Actually I do not know why RUclips gave me this video. It has been a wonderful gift. Even though the technology for these devices has advanced some in the past six years, it is still quite relevant. I am an artist who uses drawing tablets and pen displays and for me it is very awesome to have someone explain how these devices run in a way I can understand. I know the intended audience was more tech-savvy, but as an artist, getting to know and understand the tools and materials used is very important. Thank you very much for this video!
This was awesome. I couldn't understand how my device pen without batteries worked nor how to the technology detect position and angle of pen. Now I have have a greater appreciation of not just the technology behind this device but also how it ties in with USB, mices and other peripheral devices. This genuinely surprise me both how simple yet how brilliant the designs were. Thank you. Even as 40+ year old I learn something new. It gives me ideas of down things to create
"Well, that's all I had for today" after HALF AN HOUR OF FANTASTIC CONTENT The filming, editing, information were all top-notch. This is the kinda stuff I want to see more of. Also your oscilloscope is apparently delicious?
I get super excited whenever a new video from you pops up in my feed. Such a deep look into this topic, and I get the feeling that many hours of video got condensed into this clip. Whenever I see content like this just have to go work on one of my own projects! Thank you for showing us what's possible :)
LOVED the deep background/history you included at the start (first 10min.)! It helped give so much context and made me even more curious when you went inside the tablet.
Holy hot diggity dog, this video is amazing! It's like a one-stop-shop to learn about drawing tablets, and answers literally every single question I had, plus more. And I'm really glad you went though HW and SW because I was wondering what the heck kind of magic it used to scan everything. Instant sub. By the way, I think newer Huion tablets (like the one that got me to look up this video) have adopted Wacom's wireless charging technique. My pen doesn't need to charge and it's so light I thought it was hollow plastic.
This was really good! I recently dove into NodeJS HID for a project and had no idea of it’s history. This cleared a bunch of stuff up that I was curious about. It also really opens the doors to another project I have with modern gaming controllers which also use HID. Thanks Micah!
I did not nearly understand all you presented due to lack of knowledge, but the video is really really well made! Must have taken days to record and cut it, let alone learning the theoretics! Big thumbs up!
3minutes in and i already know i will be very carefully rewatching it! :) great stuff After months of Procrastination on this I gave it a shot but its really hard to follow. I don't have any background in most of the topics I guess. But it did give me a better idea of how my own Wacom works
wow, wow, wow. i'm severerly impressed by the depth of information you have provided with this video. and also this is so inspiring for me to learn more about... well, everything. thank you, scanlime.
Thank you for this review!! you're so professional , I learn a lot of knowledge from the video . Last year I bought a XP-Pen Deco 03 tablet and took me some time to get used to it. The program I used was Krita, which is amazing in my opinion.
Excellent video. That sort of explains some of the driver problems using various mice, touchpads and other HIDs on my old Thinkpads with everything seeming to fight and none of it working properly. As of March 2020, Huion Display Tablets have surpassed Wacom for featues and are relatively dirt cheap. And even cheaper if you want an older model. I will have to try looking at some of the signals with my scope. These tablets are tempting but I still prefer my Polychromos pencils and paper.
Huion/UC Logic is such a simple design. I can't imagine the prior Aiptek/Waltop tablets to have been neither simpler nor more complicated, however those worked absolutely horribly, particularly the larger sized ones, very susceptible to ambient RFI. Perhaps it's the shielding that makes some of the difference, as the edges on Waltop were unstable in particular. And thanks, this is SUCH an awesome video.
I'm glad I jumped to your video after reading about your tablet teardown in MAKE. The MAKE article doesn't do your work justice. You can't put all that detail in a two-page spread. I also had some questions that got answered in the video (for example, I didn't understand the coils in the tablet PC from the article). Please keep up the great work and keep sharing. One question, did you spill something on your o-scope? Why does your cat lick it? ; )
lol, thanks so much! Yeah, it was tough to condense the essense of the tablet work into 800 words :) My cat licks things or people he likes, I think... I try to keep him from licking my desk though :)
I'm looking for a mentor exactly like you but I failed to find all these years. Thanks to RUclips recommendation. Atlast I found my mentor. Please give me hope please . I'm begging you 🥺
Very informative! Thank you! I was thinking about making my tablet better by writing my own firmware(it has some bugs and smoothing enabled), but now I don't think that's the best thing to do, wayy too hard...
Hi can you help me in my project to use my huion small graphic table and using coper thin wire and make a big table out of my small tablet and also can I attached it with my OLED TV or led tv ( can I map the circuit behind my tv display acurately)
Hey! That was a really cool video. Could you go into the Wacom tablet a bit more, perhaps purchasing an older model for analysis? I believe they have a patent on sensing the pen while inductively powering it which is why no other manufacturer offers batteryless pens. I'm curious to see how this technology affects the hardware design.
Need help, my battery free pen isn't respond to the graphic tablet.. so when i hover and move it, the cursor in the monitor doesn't move at all - the click buttons on barrel and the tip also didn't work. I don't know if the problem comes from the pen or the tablet - I don't have all those fancy tools to check if the pen or tablet works properly
My goddess, your videos on Huion h610 are very helpful. it's kinda hard to measure pen parameters with my dodgy analog scope or logic analyzer. I was interested is it possible to emulate eraser pen if h610 does not have one or add buttons or axis to existing pen. Huion driver shows that there is stylus, puck, and eraser(in GIMP). I has hope for they are on different carrier(and ordered spare pen for experiments). But i guess driver is crap and there no extra functionality possible. Can you share schematic for huion pen? Or hi-res photos of pcb? 2 years pass, but Really appreciate if you do.
20:30 This... this is the advice that should have been given to me long time ago. When i was just diving into the hardware world I always assumed that i was just missing something, that there is some underlying secret meaning behind some magick, that there is no way this hacky way made its way into the final product, it's probably that i just missinterpreted the spec! Or there is something wrong with my tooling... Yeaaah.... It took me quite a couple of attempts of reverse engineering to accept the fact that hacky solutions exist and are quite common in the embedded world.
Wow, wait! That thingy at the end? Robot? Random.. did not understand all, but it looks interesting. Please tell us more about this weird robots. Thanks.
Micah is a software reverse engineering specialist who worked on virtual machine software for many years. She has computer science education and a self-taught electronics engineering skillset.
This happed after a serious thunderstorm. I think the tablets is not generating or registering the EM waves. Could you guide me in locating the faulty part in the circuit. I really loved your informative videos. Thank you
my question is ... how far can i revers ingineering and create my own custom graphics tablet and sell it without any cross company's right issue ... i'd like to create something that i wanna be potentially saleable ...
"So if you want to learn more, I definitely recommend reading the USB HID spec. And then after you've read the standards to learn how it's supposed to work, read the Linux driver source code to learn how it actually works."
Hiiii. Love your viedeo :-) ist it possible to change something inside the Wacom pro pen 2 to work on a wacom tablet pc example Galaxy book 12 Emr (s pen) (i need a pen with 2buttoms) is it possible ? what cause it that example i can't use an s pen on a wacom cintiq ant why i can't use a wacom pro pen on a galaxy note 10 / or any other wacom penabled tablets ? i hope u know the arnswer :-) sorry for my bad english🙈
ps ist it because the hardware (different frequency for different tablets ) or because the software (something like a code wich prevent from recognize the pen ) pleeeeeeeeeeaase im searching soooo long for the arnswer. 🐵🤔
Your videos are so clear and informative! Thanks for all of the details!
I was just about to write EXACTLY the same thing!!!
also - hi !
Was about to say that this author makes as in-depth videos as Ben (Applied Science) does, and bam! This comment :D
I'm so subbed!

CATS.
Don't have money to spare for Patreon right now but I'll definitely be subbing and can't wait to see more.
this is exactly what i was looking for!! where have you beeeeeen!

LOVED the deep background/history you included at the start (first 10min.)! It helped give so much context and made me even more curious when you went inside the tablet.
Might be interesting to connect some HC138s and LEDs to the mux select lines, to give a realtime indication of where the MCU is looking
Holy hot diggity dog, this video is amazing! It's like a one-stop-shop to learn about drawing tablets, and answers literally every single question I had, plus more.

Greetings from Sweden. Fantastic video! I am impressed with the amount of work you have put into making this video. You are an amazing person.
The best and total complete explanation about a graphic tablet that I ever had. Thank you so much!
This was really good! I recently dove into NodeJS HID for a project and had no idea of it’s history. This cleared a bunch of stuff up that I was curious about. It also really opens the doors to another project I have with modern gaming controllers which also use HID. Thanks Micah!
Explained at the rate I learn, definitely found my latest binge channel.
wow those coil arrays are so interesting! thanks for the detailed explanation!
this video deserves 10M views, u made so much effort to upload it. hats off.
I was searching for a review for my Intuos and I found this. The best review ever 😂
Thank you for the awesome explanation on how these tablets work! I really enjoy watching your videos.
World needs people like you please make such video
Fascinating! As a lot of this stuff/details still go way over my head, these didactic videos are great.
Really awesome explanation of how they work right from engineering basics :), loved it !
I did not nearly understand all you presented due to lack of knowledge, but the video is really really well made! Must have taken days to record and cut it, let alone learning the theoretics! Big thumbs up!
3minutes in and i already know i will be very carefully rewatching it! :) great stuff
After months of Procrastination on this I gave it a shot but its really hard to follow. I don't have any background in most of the topics I guess. But it did give me a better idea of how my own Wacom works
this is better than a book about usb hid and pen/mouse comm
This very nice and informative video explains nicely and in a simple way how graphics tablet works. Really appreciated.
WOW, exceptional! Just found this channel, thank you for the great high level content and delivery. Now I just need to watch all your other videos.
I've learned so much from your videos. You do a great service in explaining technology. It is very high quality content. Thank you
No one making about this topic, but you... Thx alot man your video are so impressive
INT33h -- that takes me back! Great mix of general and specific.
wow, wow, wow. i'm severerly impressed by the depth of information you have provided with this video. and also this is so inspiring for me to learn more about... well, everything. thank you, scanlime.
Amazing production, thank you for putting so much work into your vids!
Wow, great stuff. The Huion pen design really does have a minimal elegance to it. Thanks!
I'm screaming in agony as you take apart the tablets. I believe they have the capability to feel to a certain degree.
You inspire me to learn more about how things work around me
Thank you for this review!! you're so professional , I learn a lot of knowledge from the video . Last year I bought a XP-Pen Deco 03 tablet and took me some time to get used to it. The program I used was Krita, which is amazing in my opinion.

great video as always. i got that "must have new toy" feeling watching the protocol analyzer bits.
Huion/UC Logic is such a simple design. I can't imagine the prior Aiptek/Waltop tablets to have been neither simpler nor more complicated, however those worked absolutely horribly, particularly the larger sized ones, very susceptible to ambient RFI. Perhaps it's the shielding that makes some of the difference, as the edges on Waltop were unstable in particular.
And thanks, this is SUCH an awesome video.
Trogdor! I'm out of my depth watching your videos, but I'm still a fan.

good quality and creativity
I'm looking for a mentor exactly like you but I failed to find all these years. Thanks to RUclips recommendation. Atlast I found my mentor. Please give me hope please . I'm begging you 🥺
I've often wondered how they resolved the amplitude information to get sub-coil grid positioning, but never probed a working digitizer to find out.
I am so much thankful to this woman T-T so much of information explained clear and systematically i couldnt find anywhere else
Amazing breakdown, thanks
Very informative! Thank you! I was thinking about making my tablet better by writing my own firmware(it has some bugs and smoothing enabled), but now I don't think that's the best thing to do, wayy too hard...

About caption and translation. If... is it of any use to translate it to Croatian?
Really good stuff as always!
thats even more enteresting than i thought
Can you tell me how analog integrator can be used to measure Signal Strength?
Really good video, thanks!
how many turns and wire diameter on pen huion 420?
Thank you very much for this informative video. I was able ti diagnose and repair a tablet pen thanks to you.
My goddess, your videos on Huion h610 are very helpful. it's kinda hard to measure pen parameters with my dodgy analog scope or logic analyzer.

great, so would you recommend Huron, ugee tablet to anyone apart from wacom

Great video! Is a USB sniffer like the one you used here more helpful than Wireshark's USB capture (Linux)?
Awesome @scanlime Thanks
Can you use a resistive touch panel as a drawing tablet? is it better than a capacitive for this use?
-Thanks!
Wow, wait! That thingy at the end? Robot? Random.. did not understand all, but it looks interesting. Please tell us more about this weird robots. Thanks.
You have far too few subs! Good luck growing the channel. I for one have now subscribed :)
Very informative, thank you very much.
do you know how the wacom pen pressure sensor works
I wonder if you can put the huion tablet inside a monitor and transform a monitor into a pen working monitor.
Very good analysis and explanation, Micah.
Where did you pick up all this technical information?
Are you an electronics technician or engineer?
Micah is a software reverse engineering specialist who worked on virtual machine software for many years. She has computer science education and a self-taught electronics engineering skillset.
Wow holy shit you know a lot about electronics & graphic tablets!!!
Wow...
Very inspirational video.
God Bless you! You just explained why my linux Wacom drivers don't work 100%
Hey hausion PW 100 pen work on samsung S7fe tab please please please reply
I need the .hex file for my h1061p huion pen tablet mine is bricked
Wow, thank you very much
Nice video!
Hi. I have an issue with my tablet. The tablet is being detected by the computer but the touch input is not being registered.
This happed after a serious thunderstorm. I think the tablets is not generating or registering the EM waves. Could you guide me in locating the faulty part in the circuit.
I really loved your informative videos.
Thank you
my question is ... how far can i revers ingineering and create my own custom graphics tablet
and sell it without any cross company's right issue ...
i'd like to create something that i wanna be potentially saleable ...
"So if you want to learn more, I definitely recommend reading the USB HID spec. And then after you've read the standards to learn how it's supposed to work, read the Linux driver source code to learn how it actually works."
Amazing stuff!
Excellent video. I learnt a lot. Thanks.
Hiiii.
Love your viedeo :-)
ist it possible to change something inside the Wacom pro pen 2 to work on a wacom tablet pc example Galaxy book 12 Emr (s pen) (i need a pen with 2buttoms)
is it possible ?
what cause it that example i can't use an s pen on a wacom cintiq
ant why i can't use a wacom pro pen on a galaxy note 10 / or any other wacom penabled tablets ?
i hope u know the arnswer :-)
sorry for my bad english🙈
ps ist it because the hardware (different frequency for different tablets )
or because the software (something like a code wich prevent from recognize the pen )
pleeeeeeeeeeaase im searching soooo long for the arnswer. 🐵🤔
I was so curious. Now even more so!
Nice video I want more
I want to make a tablet like a intuos for experiments with it
CAN U MAKE VIDEO ON YIYNOVA TABLET AND PEN can you make a video on yiynova tablet and pen?
i love this kind of videos nice!
This was a great video
thanks this is great!! thank you very much now i can make my own :D
you are awesome please keep making videos like this!
PD: i already left my like ;)
My Intuos4 died on me. Now I need to know if it's the pen or the table the guilty part.
The cat knows best :)
That was so cool, thank you :)
Thanks
I like your channel, thanks
3:30 cat licking osciloscope
Your bright so I subscribed.
The cat is adorable
How did this 8 year old video get recommended lol
nice one
That's interesting
They send a signal to the computer and there is one chip that almost does everything nice stuff !😎😁
