I finally finished my compost bins over the weekend. I decided to build a triple-bin (turning bin) system, each approximately one cubic meter (3′x3′x3′.)

The bins are constructed entirely of cedar (renewable, weather resistant, and generally termite resistant), using cedar fence panels and 2×4s. The lids are made from cedar 2×2 deck-railing slats, covered in a square, wire mesh (to keep the birds and squirrels out.) The bins are held together with cedar-rated Deck Mate screws, which I had left-over from another project. (It’s pointless to use nice, weather resistant wood if you’re just going to join it with cheap, rust-prone fasteners. Spend the extra money on rust-free nails/screws/staples so you don’t end up with rust stains running from every joint.)
For those new to three-bin compost systems, here’s how they work:
It’s hard to tell in the picture above (by design), but the front of each bin opens for easy access. The doors are held on with a simple gate latch:

The screen lids lay on top of each bin, resting on simple guides made from exposed screws. The mesh is attached using staples:

Using cedar raised the materials cost a bit, but the extra durability should be worth it in the long run. All said and done, the materials were a bit over $100 for the whole unit (which is still significantly cheaper then buying a pre-made bin this size.)

Last year was the first time I intentionally tried growing anything meant for eating, though it was limited to just a few herbs (oregano, mint, rosemary, etc.) This season, I thought I’d expand the gardening to include a small selection of more fruitful plants. I dropped by a neighborhood “community garden” plant sale and picked up a small variety of peppers and tomatoes.
After giving them a nice, sunny plot in the back yard (and a little water in the mornings), the whole batch has tripled in size and begun budding and/or flowering. Since I’m pretty much making up this “gardening” thing as I go, I’m assuming that this behavior is a good thing.
The shot below shows one of the Jalapeno plants that has started to bud:
