Me of course! But I figured getting some opinions from subject-matter experts BEFORE starting work was a wise thing to do. If you for some reason need info about hacking or programming an old REX 6000, I'm you're guy, and am happy to reciprocate, including battery questions! 
Cheapest and also isn't a battery, only a battery case (you supply your own 18650 even though the listing tries to imply otherwise). ;-) But point made anyway! I have lots of portable power, but it is a lot of complication I'd like to avoid. Why? More equipment for one, but also I think a good number of devices will be unplugged by players and not replugged in and I don't want device batteries dying at inopportune times. (I'm hope to use these devices to streamline things during events for all involved. Extra complication of charging at night isn't an issue since it isn't happening during the event).
Yeah, hoping that simply hitting the "disable screen saver" option also disables sleep state. Will be testing that. Screen refreshing will be done via JS using data retrieved with an Ajax call, so I won't rely on meta refresh.
Yep. And I did jailbreak the Kindle last night (first one ever! yay!). It was surprisingly easy, which is a testament to the work that other forum members have done to make it so!
Yep, on this and the rest of your post. Those are the sorts of things I was trying to asking about, not wanting anyone to test something for me, just get an idea of when my sort of app might be feasible.
I think this discussion, despite its enlightening meandering, has revealed that in my case it's not clear cut so testing is the only way to know.
Great info there. Thank you. And if power budget turns out to be marginal after my testing, you just gave me an idea that I might be able to save a bit by deliberately underclocking (assuming I figure out how that's done and performance is still acceptable).
Thanks all! Now I move on to battery testing. If someone has thoughts on questions 2 or 3 in the OP, I'm all ears! |
Can I assume the people playing this game are familiar with some powered device or other?
If so then most if not all should know how to use a power bank.
FWIW: I think you are making it more complicated than it is.
Make a website or App compatible with smart phones and tablets. Buy a few cheap tablets for those that don't have a smart device.
Either make your router public or give everyone the password and the Web site or app.
Have a few cheap power banks available.
Problem solved.
