I made this compost bin after being frustrated by all the $100 models out there. I needed the compost contained to keep it away from my dogs(and other critters) but I couldn't afford the price tag of the nice ones. So I made my own.

What you'll need

A closeable container, I purchased this one at Costco for $15.
Dremel Tool or Hand Saw
Liquid Nails
Screen
A hoe or something to toss your compost
A container to transport your scraps in(optional)

Step 1: Cut Holes and Screen Them Up

Cut as many holes in the bin as you like but generally the more the better. Air is important factor in a bin, it keeps the bugs away and helps aerate the bin so you'll do less work. Plus it'll smell less. After you've cut your holes screen them in using the liquid nails. I used two sheets of screen for the holes on the side to ensure the compost wouldn't press its way out.

For placement, I've found that a little sun is ideal for my compost, it doesn't dry out being in a very humid climate, but the heat of the sun helps break things down. If you find your bin is drying out, put a tarp over the top or place in the shade. Dry materials won't break down as fast.

Step 2: Now Add Scraps!

Now you get to add stuff to your bin!
Fruits, vegetables, coffee grounds, filters, eggs shells(ground up), newspaper, grass clipping and any other plant material.

Do not put:
Meat, eggs, fish, dairy products or manure except those from herbivores.

Use the hoe to regularly rotate the compost and in a few months you'll have great soil to use in your garden.
