Photography can be an expensive hobby but if you've got a tiny bit of DIY skill, a few tools, and some free time then there are plenty of DIY photography projects to have a go at. Here are five worth a try:
Camera Chest Strap - designed to allow you to take photos while spinning a child around with two hands, though I imagine you could use to photograph any number of things while using your two hands in other activities. Looks like fun to play with and only requires scissors, some strong material, a needle and thread, and a luggage strap to make.
Remote Shutter Release - mainly for Canon cameras but apparantly also works with some Pentax and Nikon ones too. This requires a cheap handsfree phone headset and a knife and claims to be "so easy a 1st grader could do it"!
Photo Puzzle Blocks - You know those puzzles for little kids that are made of wooden blocks? Well, here's how to make one with your own photo (or photos) printed on.
Digital Picture Frame - This won't be saving you any money (it costs around $100 to make) but it will make you way cooler than your other digital picture frame owning friends!
