I always planned on open-sourcing it. However, after I got it flying I moved on to other projects and forgot about it.\nToday I decided it's about time. I didn't have the heart to clean it up much (kinda nostalgic for me now) so its still \nvery much in that dirty development stage. I did organize it for the repo though. I hope this serves as a good reference for anyone\ninterested in what makes a minimal quadcopter tick -- from the ground up.\n\n\n### Media\n![hackquad](media/hackquad.jpeg)\n![controller connected](media/controller_connected.png)\n![controller registry](media/controller_reg.png)\n![controller registry edit](media/controller_reg_edit.png)\n\n#### [Flight test video](https://www.youtube.com/watch?v=RQggOqLySJw)\n\n\n### Otherwise unlisted specs\n|Part|Description|\n|----|-----------|\n|Battery|350mAh|\n|Motors|8.5x20mm DC|\n|Propellers|75mm D (60 works too)|\n|USB-C|charging, programming \u0026 debugging|\n|Frame|PLA+ here, ABS or other gummy polymer|\n\n### Notes\n\n#### The camera\nI wired the camera connector up backwards like an idiot, but if you reverse the pin order it should work.\n\n#### Possible improvements\nSomething to make this project more practical would be dropping the camera, adding a better imu w/ magnetometer, a several watt\nRGB led, larger battery, maybe GPS, etc... and using the mesh networking capability of the espressif chips to make a very \ncheap drone light show platform. I say maybe GPS because dead-reckoning imu data combined w/ rssi info in a massive cluster might be\nenough to get stable quad-to-quad relative positional information (saving on cost of the individual unit).\n\n#### Improvements for this implementation\n- neutral boyancy\n- better IMU w/ magnometer\n- proper multi-position IMU calibration routine to correct for axes skew\n- linear acceleration control layer\n- better battery capacity estimation\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdivisionind%2Fhackquad","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdivisionind%2Fhackquad","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdivisionind%2Fhackquad/lists"}
