This mini quadrocopter would make a great spy

This little guy weighs only 20 grams and measures 8 centimeters from motor to motor. It runs on a Cortex-M3 CPU that takes input from an accelerometer and uses a couple of gyroscopes to keep balance. The quadrocopter is controlled by a 2.4Ghz radio transmitter, uses a small 110 mAh LIPO battery pack from an R/C plane and uses a PC to handle the telemetry.” via Hackaday

Want early design analysis without simulation?

Sponsored by Siemens Digital Industries Software

Traditional verification methods are failing today's complex IC designs, which require a proactive, early-stage analysis approach. A shift-left methodology addresses IP block integration challenges and the limitations of traditional simulation and ERC tools. Insight Analyzer detects hard-to-find leakage issues across power domains, enabling early analysis without full simulation. Identify inefficiencies earlier to reduce rework, improve reliability, and enhance power performance.
