Picture of USB Ambient Light

A old USB cable, few resister and after a few days/weeks this clear silicone blob finally lost its smell and I put in 2 slow changing RGB LEDs from superbrightleds.com It made a nice ambient light that is not to bright to run at night and a very odd conversation piece.

Instead of making a new instructible. Here is a little video of it.

Didn't realize that the LEDs flicker guess they use pulse with modulation.

maybe ping pong balls, then silicon around it to save on materials.
that yellow foaming insulation material just begs to be used for
some type of blob project. i like this 'ible.

I am tempting to redo the blob. I messed  it up when I was thinking about using the LEDs in a flash drive.  I will keep the ping pong balls in mind to maybe make it bigger that before.

great little project. I Like it but why bother posting it if you aren't going to actually include instructions on how to build it?. How many Resistors? How did you wire it up? ..
My guess, squeeze silicon onto paper, let dry,

when dry, drill hole for led,

hook the red wire to the positive side of the led, and the black wire to a 222 ohm resistor (or somwhere around there, above 150 is good and below 250)
then hook teh other side of the resistor to the negative (do all that after splitting open your old USB cable).

Put a small dab of silicon on led, put led into now dried silicon blob, let sit till new silicon is dry (small amounts 1 day, the blob, several)

plug usb into computer and ignore "Device is not respoding to windows, And is not recognized" error.

Then Enjoy your flashy LED blob

Comign soon to My stuff:
The NEW and IMPROVED superball!
Here forth to be referred to as, The Shockwave Superball!
It can bounce Father and Higher than the orginal 1965 supreball, and was created in home!
it only uses

silicon,
Homemade epoxy mold,
a ball (to make the mold)
a cup (to hold the mold....rhymes)
tin foil! (to get the ball out easyily
and muriatic acid!@!@!@ (to burn off teh left-over tinfoil)
and all of your time! it only took 1 month to make!

My shockwave ball is low density, and rubberish, allow for compreison, unlike the pre-compressed superball which is very Dense, do to the complete differsne one would think that the two have oppisite physics, which is partaily true.

The superball is all about tranfering engery from the impact zone, to the outer layer, this creates an upward force, my ball is about creating a sudden burst of energy that the ball compreses and release that engery like a spring, launching the ball upward. Do to the fact that its the shockwave that does this, the ball cannot be ddropped and expected to lunge uward, its not linear, so if you throw it hard it goes far, whereas if your throw it very hard it would go alot further than epected, unlike a superball where you can say if i throw it with 5 pnds of forceit goes 10 feet, so 10 pounds of force it will go 20, this is much mroe like "5 pounds of force, 10 feet, 10 pounds of force 30 feet"
not to hawk my channel stuff, its more of re-lating to your project, if you think i was tryign to recruit peopel to my channel, please delete it =)

cheers
So others can envy its awesomeness, same reason i left my http://www.instructables.com/id/Modded-nerf-Gun/ as a slideshow, jk, in all reality, it was laziness, although, Rob K, probably has a better excuse xD

very nice clear silicone and LEDs always go good together

Odd, but somehow I like it
