TI 84 indication leds
« on: June 16, 2011, 10:55:02 am »
I made this little device that indicates the state of the linkport of my TI 84. Works with all calcs with a stereo jack link.
I made a better version :) This one inverts the signal. When your calc is turned off the leds won't emit light anymore.

There is only one problem. The transistors invert the signal emitted by the link cable, so you will need a 5v battery

Wow!! Cool!! we should have an Omnimaga store with things like this!!

I need help with Random (x86 Happy), pm me if you want to help :D
LOOK IN MY SPOILER, MY SIG IS UPDATED (almost) EVERY DAY
Spoiler For MiniTale:
No mini competition please, teamwork is better :D
I suggest we do not use "MiniCraft" as the name:
Notch has asked us to not do that.
It will get changed to "MiniTale"
@Hayleia, you don't _have to_ organize :P
THIS POST IS IN MY SIG TOO

Things we'll need to do/make
Draw the sprites saintrunner is working on this
A save file format.
A level generator.
A Tilemapper.
Some sort of AI.
Crafting system.

And even more:


[07:53:14] <+Frey> Y'know, when people descend from my heavens , they're never Chuck Norris
[07:53:55] <+Frey> I usually get another catgirl or an angel pops down for a visit
[07:54:06] <+Frey> Some angels are really nice
[07:54:33] <+Frey> Some are into the whole "scare the locals" bit
[07:54:54] <+Frey> And some just absent minded
[07:55:38] * +david_ has nothing to do
[07:55:40] <+Frey> It's the absentminded ones you gotta look out for, because the'yre the ones that forget they're 40ft tall
[07:56:04] <+Frey> They're also the ones that forget about social taboos, like nudity
[07:56:28] <+Frey> Have you ever tryed to explain to an angel...anything?
[07:56:45] <+Frey> They don't listenunless they want to
[07:57:16] <+Frey> And don't learn unless they think they don't know
[07:57:51] <+Frey> Except for the nice ones, they're nice
[07:59:27] <+OmnomIRC> (O)<yrinfish> lol
[07:59:32] <+Frey> And they're all so pretty!
[07:59:38] <+Frey> It's ridiculous
[07:59:44] <+OmnomIRC> (O)<yrinfish> I hate PUSHES, THEY HAUNT ME
[08:00:06] <+Frey> Want an angel to come over and exorcise them?
[08:00:36] <+OmnomIRC> (O)<yrinfish> or, more specific: the fact that sometimes, happy outputs: pushes != pops
[08:00:47] <+OmnomIRC> (O)<yrinfish> I know why
[08:01:01] <+OmnomIRC> (O)<yrinfish> and I can solve it by adding a lookahead
[08:01:10] <+OmnomIRC> (O)<yrinfish> But I don't want to
[08:01:24] <+OmnomIRC> (O)<yrinfish> but continue your story
[08:01:35] <+OmnomIRC> (O)<yrinfish> lol
[08:03:13] <+Frey> Ok, so one day, I was walking to the school bus, and, long story short, got my life saved by an angel
[08:03:27] <+Frey> This one was a scary one
[08:03:42] <+Frey> Same height/age as me
[08:04:14] <+Frey> OMG She was the scariest person I had ever met
[08:04:28] <+Frey> She made the entire football team pee their pants
[08:04:43] <+Frey> I was so glad she was on my side
[08:05:04] <+Frey> Right up until she tryed to enter the bathroom with me
[08:05:37] <+OmnomIRC> (O)<yrinfish> lool
[08:05:45] <+Frey> After a muchness of arguing, I finally got through to her
[08:05:56] <+Patrick-D> is this a rap song?
[08:06:06] <+OmnomIRC> (O)<aeTIos> idk
[08:06:09] <+Frey> She tap danced outside my stall the entire time, though
[08:10:04] <+Frey> She was in all my classes too, which was weird, especially as they were all advanced courses and she joined in the middle of the semester
[08:10:28] <+Frey> Even the teachers were scared of her
[08:10:45] <+Frey> Note that she was gorgeous
[08:12:09] <+Frey> So, this angel and I, we managed to stop the apocalypse
[08:12:48] <+Frey> And she kissed me before going back,
[08:13:08] <+Frey> To heaven, but as it turns out that kiss sealed her to Earth
[08:13:47] <+Frey> We still don't know what to do

:) My work is open-source. You get the schemes so that you can build your own. The parts cost less than 2 euro +2,50 for the circuitboard.
If you like my work: why not give me an internet?

My next project is slightly bigger. I needded a subject for my profile essay. I decided to make a piece of hardware that collects data from sensors and then convert the analog data into a binair signal which is translated by the calc and then stored in an appvar or a list. This allows students to measure the voltage from a dynamo while the calculator converts the voltage into the exact speed of the bike. The software will also be able to count pulses and respond when a certain number is reached. This all sounds complicated. Believe me: it is :) I need the help of the Technical University Delft. Our school is in Delft, so we have good connections there.

When it's done I will ask TI if they like it :) I have to spend at least 80 hours at this profile essay.

Thanks :)
I had this in mind:
analog signal input:

Signal__________+------------+
                |AD-converter|___1_____==] USB port
                |(4-bits)    |___2_____==]
                |            |___4_____==]
                |            |___8_____==]
                |            |
                +------------+

digital signal input:
Single 4-bit,Double 2-bit or 4 1-bit signals.

1______+---------------+______1___==]USB port
2______|Voltage limiter|______2___==]
4______|               |______4___==]
8______+_______________+______8___==]


Output:

digital output:
Pulse:
(Replace the led's by a relais or use of other circuit)

Light:
Indication led that is on when the circuit is powered. Every in and output will have an indication led.

Sound:
There will be a little buzzer in the interface. This indicates overflows and several crucial errors.

The software will be written in axe and basic to save time. Maybe some asm parts for the live data stream and the usb port, but that will be it. The software will be capable of the following things:
-Showing graphs
-Voltage meter
-Imitating a certain circuit. You can make it compare 2 2-bit signals or 4 1-bit signals.
-Responding on a certain voltage by showing an image or sending sound to the 83 linkport.
-Saving data to one of the lists.
-Maybe some easter eggs :)
