Use this audio bubble level for your DIY projects

My friend Ron is blind and does a lot of carpentry and DIY work. One challenge he ran into is the need for an accessible level for putting up shelves and the like. So I put together web-based audio level that uses the orientation sensor in your phone or tablet.

The level is designed to be used with the screen up and the back of your device against the plane you’re trying to level. Orient your device so the long axis is parallel to the direction you want to level, with the top end of the screen on the left. In this orientation the level will play high-tone beeps when leaning to the left, and low-tone beeps when leaning to the right.As you get closer to the horizontal position, the beeps will become less frequent, going down to one beep per second at a 1 degree angle, before becoming silent. This way you can get feedback as you align a workpiece. If you are more than 15 degrees off in either direction you’ll hear a continuous tone.
