I'm talking massive resolution that will play seizure inducing animations

Hit me up with your circuit designs

if this wasn't mad expensive, I'd wear it

6/20/2009 1:01:30 PM

I'm going to go out on a limb and say the lilypad won't cut it....without shitloads of them.

6/20/2009 1:15:26 PM

Are you kidding?

6/20/2009 1:32:03 PM

hey, i'm a moron when it comes to circuits, but i don't see how you could control a couple hundred -> maybe a thousand or so LEDs with 14 I/O pins

6/20/2009 2:01:12 PM

yea, you're an idiot

2^14 = 16384


I would love to see you wire it .

6/20/2009 2:40:24 PM

Yea, I was looking at that yesterday. Probably will start with it just to learn a bit...

But it's purpose built for that....and the controller is still gigantic....that's why I'm confused as how you guys are saying you can build a huge multiplexed array with a lilypad

6/20/2009 2:41:12 PM

Uh, Quinn...what?

6/20/2009 2:43:26 PM

^ what he said

6/20/2009 2:43:39 PM

8 IO

2^8 = 256


if you cant figure this out you have no hope. do you know what a cathode and anode is?

6/20/2009 2:47:41 PM

Let's just talk about 3 bits. You tell me the connections that would allow you to address 8 different LEDs with 3 I/Os from a mcu.

You didnt say they all had to be on at the same time!!!!!!!!

6/20/2009 2:56:01 PM

Wait, I think I may be retarded.

6/20/2009 2:57:44 PM

persistence of vision is ghey

so, quinn, learn me

lolz

now THAT is what i want in shirt form

why don't you just follow the cube schematic? a shift register designed for LED current levels.


A decoder isnt going to make for a very exciting shirt . You could make a chaser script though!

1 2 3 <- pin pixel v
0 0 0 0
1 0 0 1
0 1 0 2
1 1 0 3
0 0 1 4
1 0 1 5
0 1 1 6
1 1 1 7

how the fuck did i pass those switching theory classes

this shit was easy a few years ago when i was actually forced to do it

Yeah, no shit. When I made the statement, I was thinking of how you could do it without additional circuitry, but no one really implied that it couldn't be done - which is why I said I was being retarded. Looking at the Peggy 2, they get around any sort of I/O limitation as it is by using SPI enabled LED drivers on the rows and use MUXs on the columns.

No, but I did read through the links this time, just like you did.

Oh, and the original

Was meant with the idea that you wouldn't use one lillypad, you'd use a lot of them. Actually, I only glanced at the stuff on that sparkfun page. I know that they dabble in wearable stuff, but I don't really bother with looking at what it is because it doesn't interest me that much. Once the technology gets a little bit better where you can seamlessly embedd LEDs for cheap into clothing, then I might be interested.

Ok, I stopped being a retard just long enough to get it all thought out.

This is going to be relatively easy (minus the programming bit...still haven't worked with microcontrollers much).

Now all I have to do is buy a shitload of equipment

6/27/2009 8:36:09 PM

i tried to find the monster magnet lightbulb suit but i couldn't really. this will have to do.
