How to Make a Soft Tip Stylus for the iTouch

Test your kitchen sponge by brushing it across the iPod touch's screen to make sure it can be detected by the device. Organic sponges typically perform the best, but you may need to experiment with different types and brands to find one that the iPod touch can detect.
Cut a rectangular piece of sponge approximately 1 inch by 2 inches. The depth is determined by the depth of the kitchen sponge, but is ideally around 1 inch.
Squash the sponge and roll it into a tight cylindrical shape 1 inch long.
Wrap the thin copper wire around half of the sponge to help it keep its cylindrical shape. Leave at least 6 inches of copper wire free.
Twist or unscrew the artist's charcoal holder to open it wide enough to slide the copper-bound side of the sponge cylinder into it. Tighten the holder to grip the sponge, leaving approximately one-quarter of an inch of sponge protruding from the holder. The free piece of wire should also protrude from the end of the holder.
Wind the remaining length of wire around the holder. Keep the wire tight, though the spiral can be quite wide. Secure the wire at the opposite end of the holder to the sponge using a piece of sticky tape. The stylus is now ready for use on your iPod touch.

How to Increase Memory in a Macbook (5 Steps)

Turn the computer over so that you can see the screws around the perimeter of the bottom of the computer. Remove them using the phillips-head screwdriver, then place them to the side. There are two different length screws, so make sure you keep them separate and note which ones go where.
Lift the bottom of the case off of the laptop at the vents near the back of the case, which will also release the two clips which hold it in place. Set the bottom of the case to the side.
Locate the ram in the computer. This is on the left side, just below a fan, and is about two to three inches wide. Push the tabs on either side of the ram away from the ram chip itself, which will pop up the ram. Pull the ram straight out of the socket. If you're installing two ram chips, repeat the process for the second layer of ram just underneath the first.
Push the replacement ram into the socket and push the clips onto the sides of the ram. Repeat this process with the additional piece of ram if you are installing it as well.
Place the bottom cover back onto the computer and reinstall the screws using the phillips-head screwdriver. Turn on the computer. If the ram is not installed correctly, you will get an error message right off the bat, so go back in and double check to make sure that it's installed firmly in the socket.
