Is the case 3d printed? What is the water resistance like for something like this?

 

Yep, the case for this prototype is 3D printed so no water resistance at all. The updated version I'm working on now is steel with engineering tolerances and o-rings. I have one of the desk-top testers and it passes ISO 22810 as high as the pressure on that goes, approximately 90m.

Edit: forgive the image quality, but that's the dial maxed out and hitting the zero pin on the way around.

 

That's the coolest thing I have seen in awhile. Nicely done!

 

Thanks! I really appreciate it.

I did a full write-up of the development process here.

 

Really nice work. Classy and creative.

Good job.

 

Thanks! I'll quote you next time someone says it's nerdy.

 

sorry, duplicate comment.

 

😯

That is awesome!!

How does the virtual dice work and what are the icons at the top?

Is there only a D-20 or are other dice rollable?

 

Thanks! The icons on top represent different dice, D4 - D20, and it can roll each of them, even several of a kind at once. Here's a video overview of the different functions.

 

I love it. I'm going to read your other link now.

I'm a wannable electronics guy. I have a bad habit of buying electronics gear and not using them. (rasp pi, arduino, etc). I think i could have been a Electrical Engineer in another life.

Thanks! For what it's worth, electronics isn't what I went to school for and I also floundered starting with a full arduino board. It was too high-level and I didn't understand what was happening at a root level. It wasn't until I started building up circuits from fundamental components (resistors, capacitors, eventually transistors and simple ICs like 555 timers) that I really started to "get" it.

 

interested in the LCD, who did that for you? Great project btw 👍

 

Thanks! You can find various places to do it on Google or Alibaba. Here's a great video by EEVblog about the process.

my only objection is do NOT called the watch "Timestop"

you know what happened back in the days when Chrysler had the "Nova" car?

Ha! Yeah, names are hard, and it's a D&D reference.

 

Nice work and what a cool watch. Transparent case would up the cool factor.

 

Thanks! I'll note that as a variant request.

 

I have a fair number of tabletop gamer friends (myself included) who would probably love something like this, especially if cased in a more D&D appropriate case

 

Sure! What did you have in mind?

 

I just picked up D&D again since giving up regular play in the... 90s? Or so. Subscribed to the newsletter. Super-cool and nerdy watch!

 

Nice! I was never really exposed to it as a kid, but it's been a lot of fun! Nerd poker, as they say. And thanks!

 

That's awesome. And to think, I'm proud of myself when I can make a paper airplane fly reasonably straight.

 

Thanks! Believe me, it took a lot of abominations to get to this point.

 

Cool.

 

Very cool.

 

Very cool!!
😎

For version 2.0 I will suggest craps mode to roll two six sided die at the same time.

Thanks! What I call Combat Mode can roll up to 12 of any given die at once, and shows the sum total. Is that what you're looking for? Although a casino-themed watch would be fun, too.

 

Love this

 

 

lol, thanks!

 

I don't play D&D, but I subscribed to the newsletter anyway. What an awesome project. I love niche stuff like this. Negative display in a PVD case would look great as well!

 

Thanks! I really appreciate it. Are you thinking a fully blacked-out version?

 

I like the functional focus. Doesn’t try to do too much but knows what is necessary. I also like the compact dimensions and legibility. A giant tacticool plastic carbuncle with tiny piggy-eyed display is the opposite of what a gamer would need.

The style you’ve chosen is what most people these days would think of as ‘dress Casio’ but it goes back to the earliest multifunction LCDs coincident with the invention of D&D. This style is popular with tech professionals such as most of the D&D players I know, apart from my son who is not in tech but wears an F91W, so there you go. Nailed it.

 

Wow, thank you. It's like you read my mind as I was designing it. I wanted something that was understated and would fit in at the office, but had some hints (in those icons) about its fun functionality. Given that LCD watches (b. 1973) and D&D (b. 1974) basically grew up together, I was surprised this hadn't already been done.

 

The 14-year-old me is drooling. Very cool watch.

 

Thanks! Fun for kids 14-41. Or older.

 

I don't even play D&D and I like this watch! Very cool. Subscribed!

 

I hope it can be a gateway drug. You'll be rolling a up a half-orc warlock in no time!

 

Just wow.

 

Curious as to why no alarm, or timers?

 

Fair question - honestly, I don't use them on the digitals I have and wanted to focus on the quickroll and combat mode functions. So I was balancing simplicity with feature set. Are those critical functions for you?

 

Wow that's simply amazing, and I particularly love the custom LCD.
I didn't realize this level of DIY was so feasible, made my day, thank you for sharing.

 

That’s wonderful to hear! Thank you.

 

Very cool and unique! To get a bit technical, how random is random with the microcontroller you're using? What are you using for a seed? As an hardware/software designer myself, this is the first roadblock I thought of.

 

Great question! I use a few different sources of entropy - current time and some internal noise - to seed a pseudo random function. So it’s not cryptographically random, but it is very hard to guess. I focused more on fairness, which it is, over millions of simulated rolls.
