It looks like I'll have to add a detent of some kind, to make sure it always stops in a defined orientation, but the flip-dot d10 works!

@attoparsec @laurenthemself I mean, your host is "clacks.link" so this appears to be 100% on-brand.

:emacs: Douk-douk :t_blink:

@attoparsec Now make it a terminal for [name of really niche retro computer]

krl

@attoparsec that's how the old airport displays worked, right?

Habrok

@krl @attoparsec No, these were split-flap displays. Plastic flaps with half of a letter printed on each side that were mounted in a quite sophisticated mechanism:

@Habrok42 @krl @attoparsec either that, or they used what was referred to as "glow cube" technology, where a cube with two painted sides (black and neon yellow) was flipped over with an electric motor.

Nini

@krl @attoparsec Yep, good ol' noisy af split-flap tech. In this case it's actually a vane display given it's representing a seven segment number, not a flip-dot display.

@attoparsec could the wheel orient vertically with magnets around the circumference? Could almost motorise this for the most high effort 4 digit display ever 🤣

meridi??

@attoparsec The transitional states between numerals is really cool

Michael K Johnson

@attoparsec You are using magnets, it seems almost required to use a magnetic detent system...

Matthew Dockrey

@mcdanlj Definitely an option. I was hoping that the display itself would do it, and while there definitely is an effect, it's not enough by itself.

Michael K Johnson

@attoparsec Repelling magnets between positions might be enough to kick it one way or another, without a separate set of attracting magnets, then?

Matthew Dockrey

@mcdanlj Well, the display itself doesn't have any magnets, so I'll have to add some no matter what. I'm thinking an inner ring, alternating N/S, with a matching one on the bridge holding the display module.

@attoparsec you could have different dials for d4, d6, etc. Add another digit and you could make a d20!

TeflonTrout

@attoparsec You go through all the effort and it rolls a 1? Typical

Michal Nemecek

@attoparsec hmm. didn't occur to me these work using magnets.

Michal Nemecek

@attoparsec you can probably attach ten magnets on the underside (or the edge) and one magnet that will attract them. Once the disk stops in between two numbers, the magnets will naturally pull the disk toward one of the numbers.

Michal Nemecek

@attoparsec don't put the single magnet too close though, that might make spinning the D10 considerably harder (if not impossible 😅)

Lockpick Extreme

@attoparsec very cool build. I can't wait to see what's next!

palenque laser codes

@attoparsec you could use a pair of magnets to make a magnetic detent!

Jayne

@attoparsec again! again!

(my inner child is very impressed)
