> After creating the first prototype I realized a number of things. While it was cool there wasn’t enough utility to justify creating another one. The only way I could have figured that out is by making and using this prototype for several months.

I did something similar with LEDs [not a cube, just a board with lights] to alert on various things before just having the Pi power an old wall mounted LCD I wasn't using anymore + a dashboard.

It is one of those ideas that is awesome in theory but its really hard to justify the time/effort beyond "FUN!"

Exactly, I agree wholeheartedly. There is a limited amount of granularity you can get with using colors. Incidentally, I'm also messing around with tiny displays now. - https://www.dropbox.com/s/r5993ylrqmjoegn/screentest.jpg?dl=...

Very cool. What I've been really searching for is a large e-ink display. I'd love to do a RaspPi powered "cork board".

Oh nice, not sure how large you're thinking but if it's under 6 inches you could probably get one decently cheap from Alibaba(the Chinese Amazon). I think the larger displays (10 inches+) were only manufactured for special use cases like the Kindle DX hence the limited availability. Cool idea though!

That looks neat. I honestly just used a standard wall mount display. ;)

I did exactly the same using LEDs and an Ikea lamp housing, with a Pi running Python to poll different APIs. It wasn't too difficult to get something simple running, but yes, hard to justify significant time!

This looks like a great first project to get introduced to some basic electronics, thanks for sharing.

the design of your website is incredible! a little hard to navigate around however, how did you build the cube animation in the top?

I think the white text against blue background is a rough choice. On the right monitor and brightness, it's fine; on the wrong one, it's illegible. Text either needs to be thicker or the color schema needs work.

I agree. I like the blueprint theme, but those ultra-thin fonts need to go away. If there is a potential for your font to render with sections being only fractions of pixels thick, you get a very illegible result.

Thank you! Sorry for the difficulty navigating, what did you have a problem with?

The cube animation are six square divs animated with css. Just take a look at the source if you're curious.

I just wanted to see more similar pages and couldn't find any! (Admittedly I hadn't considered there wouldn't be any!) I also like the thin font.

Thank you for the advice about the cube, I will definitely have a look!

Oh gotcha, yea no other pages yet. I did consider the implications of a thin font on readability but it looks great on retina displays. No problem, hope it helps.
