JohnG on ESPClicker – An Elegant Solution For Integrating Dumb Devices Into Home Assistant.Microbubbles And Ultrasound: Getting Drugs Through The Blood-Brain Barrier 18 Comments However, almost as good can be gotten if you don’t care about slow drifts, with just an additional 3 axis magnetometer chip. The GPS simplifies the position solution a fair bit. There may almost be enough spare left after this shrunk to add a GPS – at 3 grams. The radio module is quite large – – for example would let you shrink that footprint a bit. You possibly wouldn’t want to go that far. There are smaller packages for the arm cortex part, going down to as little as 3*3mm or so. The above is digital output, removing that hastle. The parts used are quite old, and this field is moving fast.įor example – – a three axis magnetometer and 3 axis gyro in the same part.Īlso – I think the gyros used are analog output, meaning extra parts are needed for stuff. The CPU has plenty of grunt for doing the control, and there are a number of ways the PCB can be shrunk. Posted in Robots Hacks Tagged awesome, cortex-m3, miniature, quadrocopter Post navigation Penn’s quadrocopter creations if you are interested in seeing more. Stick around to see a quick video of their mini quadrocopter in action, and be sure to check out our coverage of U. Either way, this thing rocks – we most definitely want one! We’d love to see if they could retain this small footprint if everything was handled by the quadrocopter itself. Wireless communications are handled via a 2.4Ghz radio transmitter, and the quadrocopter’s power is supplied by a tiny 110 mAh LIPO battery pack scavenged from an R/C plane.Īll of the control and telemetry is handled by a PC, which relays control messages it receives from the pilot’s game pad to the CrazyFlie. Since the goal was to use a PCB as its frame, the copter’s footprint from the edge of one motor to the other is a modest 8cm, and it weighs in at a measly 20 grams! The entire platform runs on a Cortex-M3 CPU that takes input from an accelerometer and pair of gyroscopes to help keep its balance. Their CrazyFlie is a miniature quadrocopter that uses its PCB as the main structure of the device. Quadrocopters are all the rage lately, and while we have seen our fair share of large devices, have been dutifully working to buck that trend.
