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.

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)

Drill the holes for the LEDs. It might be a good idea to drill the holes a little bit smaller than the LED size, cause some "5mm" LEDs are actually 4,5mm or so.

OK, now it's time to mount the LEDs in the holes. Move your mouse over the yellow boxes in the pictures to view the instructions.

Solder the LEDs together. move your mouse over the yellow boxes to view instructions

Simply press the batteries into the center of the roll. They fit so perfectly, that they're held in place by friction.

In this step, I will show you how to solder the LEDs, the batteries and the switch together. Move your mouse over the yellow boxes in the picture, to view instructions. I know, it's a bad idea to solder onto batteries, but i tried to tape it together and it didn't worked.

Now it's time to get your big geeky glasses on and roll this thing.
