I think it would be good for people to start posting (or maybe we should make another topic) should start posting ideas, maybe small pictures or there descriptive idea, and then from those people make better pictures, and finally a 3d image. And it would probably help to have pictures of what will be on the calc screen, such as the homescreen, the menus, ect. It should still kind of look like a calculator, else teachers are going to think you took your Nintendo DS XS with you to your exams...
By what we are describing it as, unless we have a very lowering press to test mode, I don’t think that this would be allowed on any test. The qwerty keyboard alone would disqualify it from every major us test.

like this one with numeric pad and a bit smaller.
http://blog.geeksaresexytech.netdna-cdn.com/wp-content/uploads/2008/10/ikitnotebookmain.png So is this going to be a laptop, or a calculator? And is it going to look similar to a nspire or a casio It would be important, or at least good, to get a general concept design or art, even though those would really only be implemented in the final stages of design. This could get more people interested in the project, If you're going to be able to connect official TI accessories to it there is a chance TI will sue ya. Just a thought. If it has a usb, and it is less locked than an nspire, then you can use usb thermometers and such, and I think it might be cool if he could get an accelerometer in the calc.

I just had a great idea that would probably not work.
Would it possible to port the nspire emulator onto the calculator with Linux?
So maybe you could use the keyboard on an nspire.

I was just wondering, would you be able to have a detachable keyboard? Or moreover, just part of it?
I was thinking a joystick like think for one thumb and a d pad for the other thumb would be awesome. And you could replace that with a left handed version of it. Or a touchpad.

I was just wondering if you had any idea how you wanted this to look, the calculator and the screen, al though it might be better if this is decided later.
I like the look of the cx, and some aspects of the screen of the prizm
Also, are you going to have a touchpad, arrows, or a flat circle that moves like a joystick?

So I was cleaning out my room today and found this binder my dad gave a year ago in a random corner.
It is kind interesting that it has a similar color and name.
However, it is a strange coincidence and almost creepy that I used this to put the nspire Lua documentation in, 6 months before I even knew omnimaga existed

Just wondering, in nspire c, can one use combo boxes?
I know you can program the message boxes with numeric inputs, but can you program ones with drop down boxes wih text choices?
Also, how can you efficiently make lists or such.
Like if i want 3 messages or 3 values there might be something like char * message[1]="string" or int value.1=number

Well, I think it should have maybe two programming languages.
TI basic is very very simple to use. Just give me something to program and I’ll program it in a few minutes.
But the thing about it is that it can’t program very much.
A few weeks ago, I was making a program to multiply numbers and keep more decimal places, by inputting strings, changing them into strings before and after the decimal point, changing those into integers, multiplying large integers, then changing them back into strings and adding the decimal point.
C++ can that easily, and much more, but it is much more difficult.
So users with little knowledge in c would not be able to program anything. And even those that can would have to sped some more time fixing syntax errors until it works.
So I think a easy programming language and a more difficult programming language would be good for the calculator

Yeah, that is the problem I have when running the bootloader, it just freezes. If you have a mac, then you can use their tutorial to allow your flash drive to work.
Elsewise, boot it from the white screen, with typing initrd initrd.tns and what not. When I do that, it doesn’t freeze, I still can’t get a flash drive to work, but I can get the keyboard to work.

I only get the delay when I run the bootloader_usb.ll2.ext file, but you have to have changed the ndless.cfg file.
Do you have the initrd and zimage files on your calc?

We can’t use our own calculators on class exams, but the people administrating the AP tests are not allowed to erase or check anything on your calculators.
So I could bring a whole book on the notepad or nTxt, and use that during the test.
Of course, I wouldn’t, but my chemistry teacher did suggest that we bring our calc with a few constants already saved in variables. And my calculus teacher was either suggesting or joking that I’ll make some programs to speed up the calculator portion of the exam.
Of course, if they saw anything like a internet dongle connected to the calculator, they would surely see that as unusual.
I have a little rechargeable battery meant to recharge phones with a mini usb, but I use it for my calculator instead, but last year at the AP Chemistry test, my cx was low on power, but I was afraid to connect that for fear they would think I was cheating.
Also, I don’t cheat; I even deleted the periodic table before the exam, so that I would not be tempted by legal but evil help.

If you are going to use a keyboard, I think the best way would be to make a text editor for linux (yeah, it has nano, but if you don’t press enter, you get one long ugly line) and try to make it so that you can save your files

When you run linuxloader2, you need to get your ramdisk and kernel loaded. So type initrd then type the initrd file location (initrd.tns, or maybe linux/initrd.tns) and press enter. Then type kernel, the location of zimage.tns, and press enter. The type boot and enter. Use this https://github.com/tangrs/nspire-linux-loader2An alternative way is to just use the bootloader script, but you have to add this to ndless.cfg ext.ll2=linuxloader2

No, I’m using everything in the snapshot download, and the most recent initrd, and I was able to get the keyboard working, but I never did
1. Prepare your rootfs. Get a USB drive that you don't mind completely erasing. In my config, I didn't have a partition table. I just ran dd if=rootfs.ext2 of=/dev/X (replace X with your USB device).
And my dongle has 4 usb ports, with my calc connected to the mini usb port, using the cord meant for calc to calc transfers, if that makes any difference.
And I don't think I imaged the rootfs onto the USB drive.
Could you make a tutorial?

Also, do you have a usb to headphone jack?
Because I notice in the video it says nosound, so would it be easily possible to get sound on the nspire?
Because it would be awesome to watch videos with sound and listen to music on an nspire.

This is some of the output when I plug flash drive
sd 6:0:0:0:[sdb] Media changed
sd 6:0:0:0:[sdb]
sd 6:0:0:0:[sdb]

Just wondering, how to you get video to work?
I didn’t do anything about the rootfs because I didn’t know where I needed to change that. (also I don’t really know what it means by “your usb device”)
Many different things happen when I try many different things. If I boot with linuxloader2, wait for it to get to the login request, and then put my flash drive in the dongle, it just spews out that the cache failed
If I put the flash drive in immediately after running bootloader in linuxloader2, it seems to register it, I think, but when I run mplayer, it outputs –sh mplayer: not found.
Then it outputs some error about the flashdrive, with /64
Whenever I do it the normal way by just running the bootloader_usb.ll2.tns file, depending when I put the flash drive in, it displayes different things, but it always, ALWAYS, results in it kind of freezing with the last text being (ret_from_fork+0x14/0x24)
Anyone know what I’m doing wrong?
