Here is a wireless, portable tool that lets you debug circuits like a pro. The Aeroscope is an oscilloscope with a rechargeable battery that lasts a fully day. It has a wireless range of 200 feet. The device is small enough to be embedded inside robots and drones, allowing users to monitor signals on their drone or measure the power of their robot as it moves around.
Aeroscope is expected to be compatible with iOS and Android devices. The companion app will be open source. This smart oscilloscope is available for as low as $259.
