Project DreamCalc Revived
« on: August 21, 2011, 03:09:18 pm »
Some people here might remember Project DreamCalc, right? Well, I never wanted it to die, in fact, I want to keep working on it.

I lost my notebook, so I lost all my ideas and concepts, so I have to start over on that.  :banghead:

Question:
I would want some help from you guys: What is a good, small screen for BeagleBoard-xM? and what about the keyboard? It would have to have graphing calculator keys, and it would have to be able to plug into a BeagleBoard-xM.

I also have a poll question.

hm that would be nice as it already includes a screen :)

btw why didnt you go pandaboard? its 20$ more.. for a dual core and a better gpu..
and it has a ti omap proc :P for the ti juiciness


btw the problem i see is where the heck are you going to get your keyboard and housing from?
and what OS is it going to run ?

I like the 92 shape better, myself. Looks like I'm alone :P

You know, if you lower the hardware a bit, it makes it harder to make software but significantly cheaper to build. Example: An atmel Xmega Xplain, a full dev board (think arduino) costs only $30. However, it has better guts than a titanium (on par with a Mega in RAM) and 128 kb of ram. Throw in your own flash chip or an SD host, and you've got a really powerful calc. By the way, the Xmega is 99% AVR-code compatible. Just an xmega chip is only $5 or $6!

Oh, and it can go up to 128 mhz! 32 mhz by default though.

FriendlyARM looks cool, but how much is it in US dollars?

Wow, I don't know.

Something Linux, small, and lightweight. I will have to write my own GUI and drivers.

EDIT: ninja'd and what? Can I see some links, willrandship?

TI-92 would be fine as long as it doesn't have a QWERTY/AZERTY/DVORAK keyboard, so it gets accepted in tests. Also it would have to be smaller than a 92, maybe more like a DS, so it fits in a pocket. Else, 84+ format would be fine.

Nice to see this revived. I am personally looking forward for this, although I can't help much since I'm technology-illiterate.

Here's a link to the Xmega Xplain. Keep in mind the Xplain does not expose nearly all of the I/O pins you could have. It was designed to be an easy replacement for the chip that goes in an arduino mega.

Edit: Sorry, that was the page for the Xmega Line. Here's the Xplain page.

Ok, so I found out graph paper is not the best thing to use for mockups :P.

Hold on guys, a mockup should be coming soon...

Glad to see you starting it again. You should make a Web Converger(OS) version of it.

I would like to see a mockup soon. Just a tiny idea of how it might look like.

But yeah trust me, if you go for a 92+ design, make it smaller. THe 92+ was so bulky it made the Nspire Clickpad/Touchpad models look tiny. :P I personally like to carry my calc in my pockets if I bring it somewhere, to not have to carry a bag or something with me.
