Pretty useful. Praying for quick recovery.

Amazing project though.

Tissot watches are vey expensive. Where did you get this watch. It cost fortune to buy one.

Really interesting! Would you mind sharing the schematic

Really cool! I have an LCD from an old car stereo head unit that I've been wanting to repurpose for a while, and this gave some good ideas.

I haven't tried any of the open source home assistants - but I might have to. Cool build.

It looks like the touch pad sensitivity is set based on an offset to the raw_value reading when the TouchIn object is created.

If you are powering up when holding the device in different positions, then this could alter the initial threshold setting.

If you haven't already done so, you may want to check the threshold value that has been set to see if it is consistent or not.

You could over-ride it so that you get the same setting every time.

I'd never heard of this book:

The focus of my module was users and interaction, rather than technology, electronics and coding, but textbook we used 'Interaction Design: Beyond Human-Computer Interaction' by Yvonne Rogers, Helen Sharp, and Jennifer Preece featured some electronics and maker projects, including the Lilypad Arduino kit that inspired me to try this! It was a bit of a learning curve.

I looked it up on Amazon and it's a silly price (more than £60 for latest 6th Edition). I bought the 4th edition for £3.36 including shipping from Ebay.

I've had a quick skim (of the book) and I congratulate you on breaking out from this awful book (my opinion of it) and actually getting stuck into trying to make something.

Was this book the primary text used in your module ?

It is always a beautiful thing when one can repurpose something that would have otherwise been trash. [emoticon:fbd079a1c4f748c5a234faee215de9cc] Nice job. [emoticon:1435ff2429184e17bc948e4f19178e1e]

Cool project. I admire the honest functionality video where the AI did not recognize all of the commands. Well done regardless. [emoticon:1435ff2429184e17bc948e4f19178e1e]

This is such a cool project and so well explained, using offline VOSK speech recognition seems to open up options for running it on dev board. Now wondering if it would be possible to have a 'mood badge' you could set the colour of by voice [emoticon:5ce50ea3f9eb49809e861e8733750338]

Is there no risk in running the "brute force" program?

Amazing build, thank you for your reference to the high pass filter, I need that in one my project, but I was facing some issues.

Very good first post, but a lot of your images did not appear when I read the post.

You should also add a link to your GIT.

Noice Undercutter dude, I'm planning on joining my high school's battlebots team. I'm in the engineering design elective and it seems really cool.
