Here is something not robot related but extremely cool!

I first saw this projet in a little book from by libray about 12 years ago. I really don't remember when, I know that I was in Fredericton at Ecole Sainte-Anne, the only french school there. It was a small little book, 1/4 to 3/8 thick. It was dedicated to rubber band projects. It was based on funny and ugly rubberband caracters that where everywhere in the book. I remember 3 projects in that book, one that really suck, one that is ok and the last one is really a brillant idea. This is the one I will show you.

If you seen my beetle robot version 2, you know that I have rise my personal bar for the making of instructables and the quality of pictures.

ps- All the picures taken in this instructable where taken outside in a sunny day. NO editing was done!

I do have a video of the device in action, I need to do some editing. It will then be posted on youtube this week.

Step 1: The Parts You Will Need

Here are the parts you will need :

1 x wooden clothes-pin
1 x elastic rubber band
Some old pogs ( remember those? )
http://en.wikipedia.org/wiki/Pogs

The tools you will need :
1 x pair of scissors
1 x drills bit the diameter of the rubber band width.

To understand what POGs are here are the rules.

Here are the rules directly from http://en.wikipedia.org/wiki/Pogs
The game can be played by two or more players. Each has their own collection of pogs and a slammer (a heavier game piece).
Before the game, players decide whether to play 'for keeps', or not. 'For keeps' implies that the players keep the POGs that they win, and forfeit those that have been won by other players.
The players each contribute an equal number of POGs to build a stack with the pieces facing down, which will be used during the game.
The players take turns throwing their slammer (also called a 'kini') down onto the top of the stack, causing it to spring up and the POGs to scatter.
Each player keeps any POGs that land 'face up' after their throw.
After each throw, the POGs which have landed 'face down' are then re-stacked for the next player.
When no POGs remain in the stack, the player with the most POGs is the 'winner'.
All players keep the POGs which they have collected (if playing for keeps), or redistribute them to their original owners.

It will bring back memories!

Step 2: Drilling a Hole

You will simply need to drill a hole throught the clothes-pin.

You can start with a smaller drill bit and then finish with the a bigger one.

Step 3: A Other Way to Drill

You can disassemble the clothes-pin to drill it.
This could help you out.

I took a smaller dril bit to make the first hole so I do not break the wood.

Step 4: Passing the Rubber

You will now pass the rubber band through both hole you just made.

Step 5: Getting a Got Grip on the Rubber

You simply follow these next few step.

Open the clothes-pin and get one loop in it.

Step 6: Secure the Rubber on Top

Secure the rubber on top and do the same thing like the previous step.

Step 7: The Throwing Appendice

Pull on the one of the two piece of rubber between the clothes-pin.
You will need to give some slack by pulling on the rest.

Give yourself a nice big loop.

To small and your pog will fly harder but you might break the rubber band.

Step 8: Making the Weapon

Get those priceless pogs of yours.

You need to cut a V shape in them.

If your not old enough you probably don't know POGs!
Just take a peace of thick cartboard and cut circle out of it.

Step 9: Ready

Your know ready to test your device.

You simply put the POG in the clothes-pin.

Step 10: The Thrower Is Now Activated

Pull back on the rubber band. Remember to press and hold the POG in place. If you donât the POG will ejected automatically.

You simply press down on the clothes-pin to hold down the POG, then you pull back the rubber band and insert it in the noch.
