Ah I remember this sent me on a big Tim Rogers binge

Yea I was curious about something like this — can’t justify starting another blog/feed beyond the two I self-host, but would like to participate in some of the leaflet fun.

this is perfect down to the Reddit source icon

I remembered/looked up shaderbooth.com and it is good!

Also did a 3 card one - different tags all get IDs which makes me think of doing some sort of weird physical variable assignment thing.

More experiments with Apriltags:
a color-picker where
x=red
y=green
rotation=blue

freeform physical slider feels interesting

You can also just write stuff down -- post-it note album covers might be fun.

folk has a nice guide on this stuff folk.computer/pilot although there projector suggestions seem out of stock

I'm happy it's bright and also in eco mode (which is generally bright enough) the fan doesn't run all the time.

It's possible you could go cheaper and be fine -- I found it tough to decipher what projector spec differences would mean in practice.

Sure - I got this one www.amazon.com/dp/B0CQ3Y6GN...

it's about 3 feet above the desktop and 21 inches tall on the desk.

I settled at 1080p bc the jump in price for 4k was big. Text seems real readable but i'm not doing prolonged time on it. This is the DIY mount.

This works pretty well just asking Gemini. Sometime I'd like to do a version based on embeddings of my personal collection.

I think this could be cool in a shared space?

Book-to-soundtrack experiment - a projector setup where I send the book image off to an LLM for recommendations and then play with Spotify.

Meant to be kind of like putting on a record but for objects. (I clipped out the loading times.)

I got two - going to probably mount at 45 degrees and experiment. Still getting used to the sizing rules - maybe I should get a big mirror to flip up from the desk to shift from desktop to wall.

A curtain is kind of a physical shader.

I got a mirror to experiment with the projector

Now I'm thinking about SandScape tangible.media.mit.edu/project/sand...

Trying out april tags. Thinking about how it could complement hand tracking and vision models.

This is using github.com/arenaxr/apri... and I know what april tags are because of folk.computer.

Two-hand gets a bit more interesting

grant @grantcuster.com · 24d

I did (imo) get a nice setup for adding a class that automatically sends up and checks in elements coordinates against hand-tracking positions.

grant @grantcuster.com · 24d

Getting a feel for projector and hand-tracking possibilities by experimenting with a color picker. I can use pointer finger without pinch if I give it a path where it doesn't have to go through other things - kind of like a maze.

Trying out hand-tracking triggered buttons and some simple LLM calls. There are definite limits imposed by hand-tracking and projector display - but they're kind of interesting ones.

grant @grantcuster.com · 27d

With colors - this wasn't working well at first but I realized it was because the shift in light was throwing the webcam's auto-exposure. Turning on the overhead light fixed it.

grant @grantcuster.com · 27d

Table buttons for the projector - hand-tracking and triggering on overlap seems generally promising.
