Picture of LED Rollie

The LED Rollie is a pretty silly, but funny thing.

Simply roll it through your neighbourhood and you'll gain a lot of attention.

I got the idea of the LED rollie when I was bored, and I saw this roll of solder, but without solder. I found out, that 2 AAA batteries fitted perfectly into the center of the roll.




Step 1: Parts you'll need

To make one LED Rollie you'll need:

a Roll of solder, with no more solder on it.

Some LEDs (I used 2 5mm diffuse blue LEDs and 2 5mm diffuse green LEDs)

2 AAA batteries.

Some hookup wire.

an on/off switch (optional)

Kinda ironic how it's made from a solder spool

really shouldn't solder on the batteries...
BUT...
hey the more dangerous it is the better = )

Yeah. I know It's a bad idea, but if you do it for a short amount of time there shouldn't be any problems, hopefully ;-)
there are more dangerours tyhings to do than that
LOL =D

What can you use to substitute the roll of solder?
bandage tape or cloth tape without any more tape can be a good substitute.
Almost anything, that's round. Just use your imagination.

what happens when the batteries die off?
then you'll need to desolder them and insert some new ones, however they last pretty long.
you can desolder???

I love it! I bought some new LEDS just for this!!!

may i ask how long the batteries will last? thanks.
Actually, I don't know that, because I don't use it so much, but I think it will last for 2 days of continuous use.

wouldn't it be more fun to add a low speed motor with a weight, and make that thing spin by itself, at least in a circle? a counterweight is probably needed on the other side lI mean like that:

That's a very good idea. how did you make the 3D drawing?
u mean that's good?? it took my like 10 min and I didn't even rendered it anyways, I use google sketchup. it's really easy to use and u can render the images with some add-on(forgot the name).

Dude, sketchup? why that when you could used decent software like solidworks, pro desktop or even (if you had one million dollars), Catia. Nice instructable though!
another simple wat to make it roll would be to have some type of foot attached to the motor instead of a weight and have the foot hit the ground and kind of drag and the motor and the whole rollie thing woud spin and the foot would stay stationary. then you could use a high speed motor. I think two motors would be needed tho... and i also suppose that its alot of bs to go threw for a lighted spool... but then again if you unleashed a whole fleet of the things on a large parking lot, or a street, mabey at the mall...better yet the second story, now thats worth the effort
nah it won't work. it'll have to "scrape" the surface it touches, so I think the weight or nothing at all is better
yes it does work I've built something similar to this for a school project. It was a two wheel vehicle for a hill climb. It had a single aluminum rod about an 1/8th thick and it was at about a 35 degree angle below horizontal with a small upward bend at the part where it made contact with the ground it was far lighter than building a third wheel and the body to support it.
sorry then..
Looks to me like it was modelled in 'Rhinoceros 3D', and rendered using 'Penguin'... if it wasn't, it could have been!
what do u mean in: "if it wasn't, it could have been!"?
I meant if it wasn't done using Rhinoceros 3D/Penguin, then you could get the same effect by using Rhinoceros 3D/Penguin. You can download an evaluation version from their site to try it out. www.rhino3d.com. I use it for work.
doesn't Rhinoceros 3D/Penguin mean exactly Rhinoceros 3D/Penguin?
I give up.
yeah, I've always been good at annoying people..
Or take a zip pull, put it around the axel of the motor, and let it push against the ground, like an elecric Cotton reel tank

alas, thy can begin mage career. i should build one with red and orange to give the illusion of mario's fireballz

yeah, it kinda looks like that, but AI can simply increase the framerate to make it look faster

Wow, those look really neat! Nice job!
I'm sorry for the really late answer, but thanks for the comment and thank you for featuring it.

The rolly is an awsome idea, but on step 5 shouldn't it be they fit to perfectly?
What do you mean?
well you said "the fit so perfectly" and don't you mean they fit so pefectly.
