Meet StandiT: a smart kit that turns your existing desk into a sit-stand desk you can control using a control panel, a smartphone, or your voice. Its apps are available for iOS and Android devices. Each leg can carry up to 100 lbs of load. StandiT recognizes when you are close to automatically adjust its position.
StandiT is Bluetooth enabled and Arduino compatible. It has a height range of 27″ to 44.5″. StandiT simply lets you create your own smart standing desk. This is a Kickstarter project.
