How I ported T9 Predictive Text to run on a microcontroller 

This is really nice dude, you honestly deserve more subscribers

When I was teenager I was struggling with the pre-T9 phones and sending a single 160 char SMS was a real pain. Once the T9 came out (got it on the Nokia 3330) it was a real relief... so I really loved this project! As per the iPod one, I love the open source approach. I think I'll try in the future to build one of these! Thanks!

Great video! Very interesting. I'm excited for the fall and winter things. Thanks!

Just placed an order! Can't wait to assemble my new keyboard! Keep up the great work Guy :)

Hey, Suki here. Really love how you give a deep explanation of the technical part! I really enjoyed it. It's good idea to split the technical part from your initial demonstration video, cause it would be a very long video if it is combined. Looking forward for your future project!

I grew up (genX) to mobiles before t9. T9 was a great improvement. Ive been fascinated by these small "one hand typing" style projects, thats why I tried to recreate the "frogpad". But Id like to see this, its like a plover stule chording keyboard too.

I had this idea long ago when I realized how great Nokia T9 is Thank you for creating this. Hoping it works with chrimebooks

I really enjoyed this deep dive!

Really great explanation , you've got yourself a new subscriber

I literally had the idea of making something like this, and you've beaten me to the punch :P

Hi, absolutely brilliant job.……. Love the video.… Very informative… I’m currently enjoying the T9 pad that I bought from you, it’s really helped… :]

I'm an absolute f*cking idiot, but I love watching your videos. It's like watching actual magic.

I love it! Would be awesome to have this on the side. Two questions. What switches is the completed product using? And when you use this, do you have a case for it, with rubber feet and such?

Amazing video, but I walked away with 2 questions: 1.) How do we enter numbers? 2.) How does it handle words that are a complete word by themselves(like "go") but can also be prefixes to other words(like "going")? In other words, how does it know when the current word is complete and the next word is about to be typed in?(I was 5 years old when I last used the T9 keyboard, and I did not know how it worked back then.) Great work, and I am genuinely surprised that you are under 10k subs,.

It would be cool to use a library of commands or functions instead of regular words so you could write or use programs faster, or even to avoid having too many keyboard shortcuts. Maybe even implement a similar algorithm for a full size keyboard.

definitely going to mess around with this! Though I'm thinking of using a 2x4 macropad instead to make it easier to use one handed while wearing a brace. If there's anywhere I can tip you that would be great! (something like ko-fi?)

I like the standalone tech breakdown format, definitely understand everything as a person that didn’t go to computer science related school. Question: what happens if the word you are typing is not in the trie/tree?

Really cool project. Thank you for this. One question, if I may. How does it handle a custom library with latin extended characters that includes words with as ü, ş, ğ, ö etc.?

You kick the llamas A$$.

Do you think it would be possible to attach some kind of Bluetooth module to this to make it wireless? I'm trying to find a solution to typing on the steam deck that is portable, not an actual keyboard and not the digital built in one. It'd be cool if this could be shrunk down to like an old Nokia phone sized keypad and connect to a computer wirelessly.

How much power does this keyboard consume? Trying to make a cyberdeck and would love to use this as the keyboard.

Hey Guy - my father-in-law is a popular author who writes full novels, one text at a time, on his old Nokia using non-predictive texting. He then sends these to my mother-in-law, who compiles them for his publisher... it's an arduous process. I was wondering if your keypad could be made to work without the T9 algorithm/library and work exactly like the earliest, manual, Nokia texting experience including punctuation and capitalisation? He has major dyslexia and dyspraxia, so learning the qwerty keyboard/a new smartphone without tactile feedback just isn't an option for him. His eyesight is starting to deteriorate so I'm trying to move him off the tiny phone and onto something larger. The UK are also switching off 2G network support soon, so his old phone will become nothing more than a fancy brick. Ideally, he would also need the four arrow keys and a backspace button to really make it complete for him as a full rich text editing device, but I could add these keys separately. Is there anything you can think to do? Also happy to pay to support any work you may need to do.

Hey, do you want to teach CS on my college? Haha

How can I order one?
