I was thinking of a wearable
An arduino is cool if you just want one or two. Especially the
Lilypad. For instance, the wearable inbox project uses lilypad. They have a power supply that can run on one AAA battery. Also this beginners kit has a Lithium Polymer battery. That gets power out of the way.
Then there are other things such as
wearable thread and wearable LEDs. You can actually get right into the game for just $75.
This was great when we are prototyping or making a one-of educational project. But what if we want to make a larger number of them like 50 or more?
Intuitively I know my
launchpad might be an answer. If I’m understanding it’s supposed to be used to program a chip which you then add to your own project. The system provides debugging and stuff. I’ll have to take a look at that.
Others are already making little badge type stuff that’s

This stuff isn’t so wearable since the power supplies have not been worked out for that. They probably are quite prickly too.
But they’re using pics I think and their component lists look sorta long:

What to do….
I’ve got lots of ideas of stuff to do with
MAX7221 is a good candidate to start with (I think).
I just ordered one and will give that a whirl.
ideas. More. More.
I’m adding a few resistors and LEDs to the ArtEngine community parts shelf tonight.
I’m getting some LEDs for projects. It seems it’s way cheaper to buy them in bulk rather than onesies and twosies.
I’d like to figure out how to easily control lots of LEDs. I think it has lots of potential as a feedback mechanism.
LED’s might be a fun project. A larger number of them may be more interesting.
I guess the basics
led hook up is to use a resistor since they are lower impedance.
I was just looking at that and think that
Charlieplexing might be a way of getting lots of LEDs going for a fun project ( another).
Shift registers are another thing to consider. Here’s a project.
There is also some talk in the
adafruit forum. Also the Arduino forum ( another, another, another).
Here’s a cool video of a
8x8x8 cube of LEDs.
Bill from Winona wrote a blurb on incandescent bulbs.
It will be interesting to see where lighting goes.
The compact florescent are pretty nasty (full of chemicals).
Have you been bringing your florescent bults to the right recycling depot? Or just throwing them out?
He brings up a good point that LED’s are starting to emerge. I see them in traffic lights, tail lights and lots of other applications already. Perhaps that will be the best lighting source.
This looks like something interesting to put on your wall.
I think it would go well with the generator concept on my “Electric Rooster” kinetic art.
I will look into this.
