  1. I see that the 2020 Hovergames challenge is open until the end of July. I think that this type of challenges are great especially for educational institutions. https://www.hackster.io/contests/hovergames2 Also, I really liked NXP's recent collaboration with FliteTest in which they together designed a tail sitter drone. I've built drones using open source software as well as several FliteTest's DIY planes and this looks like a great combination so look forward to the plans being available. Also I just followed the NXP presentation at this weeks PX4 summit and will post the link to this thread to the YT recording once its a standalone video.
  2. It starts, today (Monday, July, 6) at 8:00 am PDT and registration is free. https://px4.io/virtual-2020/ I don't think that you actually need to register and can watch it on youtube live.
  3. You may have seen this interview that Gary Mortimer, founder of sUAS News did with Henri Seydoux CEO, Parrot. Henri explains how Parrot got into the business of making drones and more recently how they got involved with making a drone for the US Army which resulted in a commercial version called the ANAFI USA.
  4. Looks like DJI may have some serious competition in the area of search and rescue with this new drone from Parrot. It seems to be an ideal drone for first responders as it has 3 built-in cameras that combine provide a 32 times zoom as well as thermal imaging plus its manufactured in the USA.
  5. Interesting new drone from Parrot https://www.parrot.com/us/drones/anafi-usa Price $7000
  6. Welcome @Nightwatch Rick to this forum. If you not already aware of this podcast you may find it interesting as Chris interviews drone pilots from around the world. https://thedronetrainer.com/drone-podcast/
  7. Ok, I understand but that's quite a task. For a start you need to add sensors to the Pi. The basic sensors would be a gyro and accelerometer but then you might want to add a barometer or range finder for altitude and compass and GPS for direction and positioning. As I previously posted there is a "HAT" for the PI than makes it easier to add these sensors. https://emlid.com/navio/ Even though you need to develop the software from scratch you may want to leverage from existing open source software like https://ardupilot.org The software, which will run on the Navio boards, can also be run without the hardware in a simulation environment which could be a good way to start. https://ardupilot.org/dev/
  8. Hello @Muritadha I prefer keep any communication to this forum.

    Powering my drone

    That's too bad. That hardware has been "end of life" for awhile now and the last version of ArduCopter that will run on it is 3.3 and the latest is 4.x. That being send APM and 3.3 should still work. If you have a 3DR type power module then it will pass battery power to the ESCs and also supply +5v to the APM but you should have a separate BEC for the raspberry pi. Some ESC have a built in BEC but I see that the ones you are using are "opto" and don't have a BEC.
  10. Have you calibrated the ESCs ?. If not you do this by connecting a ESC directly to the receiver's throttle channel. Do one ESC at a time without the the flight controller involved. First make sure that the props have been removed. Turn on the transmitter and move the throttle to full. Connect the battery so the ESC and RX are powered on. You should hear some beeps and then move the throttle to minimum. You may hear some more beeps. Disconnect the battery. Reconnect the battery and check that when you move the throttle up the motor RPMS increase. The above procedure sets the min and max range for a ESC. If you already did the above and its still not working then what happens when you change that motor with one that's working ?. Does the problem move or stay with the ESC ? what happens when you connect that ESC to another port on the flight controller ?. Again does the issue move or stay with the FC's port ? If the issue follows the same ESC its possible that the configuration has changed or was not set like the others - what make and model of ESC are you using and what firmware is loaded ?.
  11. If you are referring to the FAA part 107 certificate then you don't have to take the "Initial" test again but the "recurrent" test which is a subset of the initial test (less topics and questions). https://www.faa.gov/uas/commercial_operators/become_a_drone_pilot/
  12. Hello @Sana and welcome to the forum. To use a Pi as a FC you need of course to add sensors (gyro, accelerometer, etc) that are typically built into a FC like the Pixhawk but it looks like there is still a solution from https://emlid.com/navio/ Like most I personally prefer to use a Pi as a "companion computer" connected to a FC like the Pixhawk. Maybe you could provide some more details about your project and what you need to demonstrate to your professors.
  13. Some new hardware (design) from the PX4 company https://auterion.com/skynode/
