Just now discovered this thread... interesting that what the OP requests is already available on the open market... just not in the form that was requested. I guess I sort of agree with
@Harald Kapp (and
@kellys_eye and
@Martaine2005) about
@Delta Prime's presentation persona here on Maker Pro. When he (if a "he" he is and not a "her" or an "AI") first started posting here, my first impressions were not good. But I have seen much improvement in the public presentation of Delta Prime. I think this will continue, but folks here should realize that we have a young genius in our midst. And most genius that I know, or have known, have a very low tolerance for stupidity. Which is not to say that such genius should call people out on their stupidity, or use such speech constructs as to imply stupidity. I learned a long time ago that stupid is curable with education, but dumb hangs around forever. My solution has always been to avoid the dumb (the unteachable) and seek out to learn from the genius among us. It is what attracted me to ElectronicsPoint initially... well, maybe, or maybe not. I do remember the conversations having more substance and a healthy back-and-forth dialog back then, compared to what I mostly find here today.
I am amazed at the Z-Generation's whole-hearted embrace of electronic gaming. Not too amazed, mind you, since I was addicted to playing
Computer Space in the 1970s at the Dayton Mall kiosk, when it first hosted the twenty-five-cents-to-play video game. This awful addiction required an entire roll of quarters to satisfy each time I visited the mall and led to the purchase of an Atari video game... for my children of course. Just like Dad purchased that Lionel electric train set as a Christmas present for me and my brother sometime in the late 1940s. Dad did keep adding rolling stock and engines as the years passed by, just as I bought every game cartridge that Atari sold back then. At one time I even thought about making my own game cartridges, but before the thought could evolve into hardware along came the personal computer. Out with the Atari. In with the Commodore. And, later, the clone "IBM compatible" PC.
Please excuse me if I don't get excited about yet another "electronic dice" project. IIRC, in the 1960s someone published several circuits based on NE51 neon lamps wired up as "ring counters" that ran faster than the eye could see (thus appearing to be continuously illuminated) as long as you held the "roll the dice" button down. Release the button and just one of the NE51 lamps remained lit, indicating whatever you wanted it to indicate... numbers, letters, words... whatever. Today we would use a PC and a pseudo-random number generator. Maybe dress it up with fancy video graphics showing one or more dice rolling and finally settling on a specific (pseudo-random) value. Online "one-armed bandits" gambling games do this, and there are probably other online "gambling" apps that simulate other "games of chance" such as baccarat, roulette, craps, etc.
It is definitely in the realm of possibility to make a d20 die, of appropriate size for a board game, that can be remotely "read-out." But, as
@Bluejets said in his post #11, it requires miniaturization techniques and the ones required are waaaay beyond the capabilities of this hobby forum. The sensors (accelerometers), the computation hardware (CPU), and communications (Bluetooth) already exist. This is intellectual property that just about any semi-conductor fabrication facility can manufacture at just about any feature size currently available... nanometer features are possible. Prepare to spend a lot of money to get there.
