Great news, I played with the Pi Pico a few months ago: the idea was to make certain 3D printing products I produce not just dumb miniatures, but "alive", doing something. The Pi Pico price point and capabilities were perfect, but the lack of wireless capabilities AND the fact there is no display with a sane price point, made the project economically impossible.

I've been using the Pico to drive a screen successfully: https://slint-ui.com/blog/porting-slint-to-microcontrollers.html https://slint-ui.com/blog/porting-slint-to-microcontrollers....

  Sure, it can drive screens without issues. The problem is the cost of the screen. If I'm selling, right now, a plastic miniature for $20, if I can make it "smart" and selling it for $30 or $35, that's ok, but $50? Nope.

    you can get screens for under 10$ eg https://www.waveshare.com/pico-lcd-1.3.htm https://www.waveshare.com/pico-lcd-1.3.htm or https://www.waveshare.com/pico-lcd-0.96.htm https://www.waveshare.com/pico-lcd-0.96.htm

    How much screen do you want? Have a dig round on aliexpress, some of them are dirt cheap if you want a small TFT, and some are designed specifically for use from the pico.

The tiny OLED screens are often under a dollar and you can stuff them into basically anywhere, and run them off anything. Sure they're low resolution and monochomatic, but often it's all you need to bring something to life. The total BOM cost for showing some short animations on one is likely under $3.

  I was just eyeing this product this product the other day: https://www.keebmonkey.com/products/megalodon-triple-knob-macro-pad?variant=42941582409943 https://www.keebmonkey.com/products/megalodon-triple-knob-ma... That right there is one of those cheap screens, right?

    That's one of them.

    In my experience, the very cheap oled screens are usually quite a bit bigger than that. Closer to the size of a smaller smart watch (with much lower resolution of course)

Not hadd that issue myself and quick check https://thepihut.com/pages/search-results?q=oled&page_num=3 https://thepihut.com/pages/search-results?q=oled&page_num=3 shows few cheap options, sure bit more than the controller but equally, not bad and more so not the cheapest place either (though not the worst and more walk in highstreet ballpark fair price). Though your bangood and aliexpress's will have cheaper options and in volumes you start to see the price slide down nicely.
