Build your own tilt switch

Tilt switches come in various forms and sizes. Well known are the mercury switches, that are obsolete in most countries now due to the hazardous metal in it. These days most mechanical tilt switches contain a metal ball that makes or breaks the contact.
 
These tilt switches are relatively cheap to buy, but in the true spirit of this building community , we'll make our own.

Step 1: What do we need.

We need:

 

1. A metal ball: Look in old ball bearings, or buy a new one.
2. A 90degr male header
3. A piece of veroboard
4. A tube: Mine is an acrylic tube with an inner diameter of 7mm and that is perfect for the 6mm ball
5. Glue, solder and soldering iron

The perfboard is uneccessary, btw

And for the pins, a broken sewing needle/pins, or paperclip.

for the plastic tube, a discarded stick pen with the ink cartridge removed. Great instructable, btw

BB ammo should work fine
