level

​Everybody knows, it's dangerous to climb an unsupported ladder. Balco Lifestyle is trying to make things at least a little bit safer, however, with its currently-crowdfunding Step Smart – it's a device that lets you know when the ladder is starting to lose stability.

When it comes to hanging things on a wall in a straight line, a laser level can go a long way towards making that easier to accomplish. A new device called Sure Hang aims to make the laser level even more useful by allowing it to integrate directly with a tape measure.
