A blue flashing light has been mounted beneath the drone. The electronics from it has been removed and will be replaced with a more powerful diode. The light also had a siren which was removed because it was too low. We have found a real siren that we will order. @tobiasrj20 will specify the details.
The needed components have been fetched from the component place and it needs to be built. @TobiasLundby knows the circuit and should be able to make it within a couple of hours. A logic converter board (3.3V to 5V and the other way around) has been ordered from SparkFun which should make any logic level problems easier and it is maybe also suitable for other applications or digital components.
The LED we want to use it a link (10W white LED powered by 12V thereby drawing ~0.83A)
A system using an Arduino Nano along with programmable LEDs and normal LEDs has been developed and this is documented in the wiki.
The program used for controlling the LEDs, siren etc. have been tested on a more realistic system. There has also been made a quick circuit for mounting on the drone.
A circuit along with serial wiring to all the LEDs on the drone has been completed using just one UBEC; the new ones had not arrived yet. Upon testing it was discovered that the MOSFETs did not react as intended. Fixing this error was postponed since testing and gathering flying hours with the whole system was deemed more necessary.
I think I've found the bug in the made PCB; P.S. drain and gate of a MOSFET should be connected correctly. This has been fixed on the PCB but the PCB has not been tested. Alongside both a circuit has been made and documentation of the headers on the PCS for easier connection by the rest of the group.
The HI (human interaction) has been put on the drone. It has also been connected to the RPi for control and sucessfully tested.
