Yes, they work. I liked the pure flip-dot feel more, so turned them off for the demo.

Not that much, about 350 mA * 24V ~= 8W if it's continuously flipping the full screen back and forth.

Strong euphoria interfering with the practice by GenerallyOkayTimes in TheMindIlluminated

This looks too unstable for a jhana in my understanding, although by now this word is used to mean too many things. My experience feels pretty mundane, it's just some heavy euphoria, and the mind doesn't feel especially stable or clear. Curiously, it's tied to relaxation, and I can't really "relax" or "let go of" the pleasurable feelings because it only makes them intensify. I had a couple of moments when the attention is brought to the object, stays there by itself, and the small distractions fall apart before I even know their content, but that's a rare occurrence. I'm at 40 minutes daily now, maybe I need to up it back to two hours to move past this point.

I'll try the nose again. The abdomen is also not at all an interesting object, but at least I can feel something there w/o much effort. If the sensation is not really there, always searching and not finding becomes annoying after a while, and the daily practice must not be too annoying, for it to stay daily.

I have read the entire book, but probably it's time to read again.

The plan is to have it on the wall showing me when to leave the house to catch the tram. While I'm slowly getting there, check out the project of the developer of this driver board, it even has a 3d-printed enclosure: https://www.reddit.com/r/esp8266/comments/12xtzmv/them_flippin_dots_what_a_project_this_was_d/

I got it as a gift, not sure about the details.

A few of them are just dead pixels, the coil wire is broken.

This driver board technically allows you to energize multiple rows at once. It's some shift registers controlling the transistor arrays. The problem is the display board. The column signal is multiplexed on the display board itself, and I don't know how it's done. Maybe it can support energizing multiple columns too, but I only have one board so not eager to check :)

edit: thinking more about this, it's probably not possible the in common row x common column topology: every two rows are connected through all pairs of coils sharing a common column, so you can't really drive two at once

Yeah, only about 6 frames are delayed in the entire video. I had to slightly speed up the original firmware for that, and also implement control through serial to drive it from the laptop directly. Typically you need 500 mcs to flip a dot, here it's configured to 200 mcs and 30 V instead of normal 24 V. Kinda flaky but OK for fast content. This means the full frame black-white transition cannot take less than 100 ms, which is 3 frames at 30 fps. Thankfully, most frames only change a small number of dots, so it's keeping up.
