it started with the thought of how to create a simple unpredictable electronic device.
its so simple its embarrassing
but
once you start playing around with it, you just cant stop
trust me

1.A bunch of LED's - there is no right amount - it works with 1, starts to look cool around 15 and just gets cooler as you add more. here i used 150 of the cheapest LED's i could find.
2. A 3v battery - one is enough but once i had all these LED's i felt like adding an extra 2nd battery.
3. A transparent sphere - i used those u can get in ant hobby store that are made of two parts, the come in many sizes and are quite cheap and handy.

Just some ideas
---> 73's, A-BOMM <---
this way short-circuits are impossible as there is always at least one led
if there were more than one battery you just have to make sure the led is always at the same pole
the downside is if the led on the battery breaks, the battery is useless too
Due to the random nature of the connections, wouldn't it be possible to have a SHORT CIRCUIT of the battery or batteries itself???
If so, I think a soon GREAT LEAK spill from the battery or could even let explode the little battery... SURE nothing that could harm enybody, but not a comfortable thing lying over there.
Or, as a minor fault, the formed random-circuit could simply DISCHARGE THE BATTERY in little or no time: so we could have a short-circuit WHILE the gadget is on the shelf....
anybody agree?
For what I think, this could be *the solution* of the little discharge-battery-dilemma!
Even if the project is so easy and straightfoerward to build up, I think, It would be a bit annoying to have it with discharged battery whyle showing it to somebody!
I'll suggest the author to add a step and complete the whole thing with this wire mod.
This way, from my pov, the project could be considered COMPLETED.
anyway a +GOOD IDEA+ ! ! !
Congrat's gedda!

I mean to be honest even though someones said there is a possibility that its going to happen, no one really cares. This is supposed to be treated as a fun project and not a "think of ways of making somthing dangerous" project.
Im not saying you are wrong in any way just let the people have there fun without bringing all this danger into the equation.
I think you would need something else fixed to the inside of
the ball to trip up the LEDs. Otherwise, wouldn't they all just
sit at the bottom of the sphere while it rotated beneath them?
I also think that the sporatic nature of the resultant circuits
would cause the intermittent lighting of the LEDs to resemble
that of fireflies.
*COOL*
Very cool. If I can find a ball like that, I'm going to make one!
I hope you are able to find such a ball
for your Spinning Water Sphere project.
If not, there's always glue to affix your
very own, home-crafted protrusions.
Think outside the box or, in this case,
inside the sphere.
Good Luck, JermsG.
as for the LED's. i bought them in a professional electronic shop. I'm guessing the details are irrelevant since i live in amsterdam.

Great job!
i am absolutely sure its completely harmless. though you are right about the fact that i shortens a bit the working lifetime of the LED's because of the inaccurate voltage.
be safe
