It all begin with this.

                            The drone we work with.                                                                                The geometric constraint

Prototyping the circuitry

                              The signal processing circuitry

                                    On a breadboard                                                                                  That's the infrared photodiode (BPV22NF)

Signals on the oscilloscope

                                                                                                                         There are many cycles. Each sweep can be either a horizontal or a vertical sweep, from either base station.

               See the omnidirectional pulse and the sweep pulse                                                      Need to identify them by durations of the omnidirectional pulses.

PCB Version 1

                                       Front Copper Layer                                                                                           Back Copper Layer

                                    Fabricated by JLCpcb

PCB Version 2

                                        Front Copper Layer                                                                                          Back Copper Layer

                             Also fabricated by JLCpcb

( I forgot to update the silkscreen.. It should be muro_r1_v2 instead )    

Procedure of soldering with an reflow oven

                                Taping it down.                                                                       Putting stencil on top. And smear solder paste over it.

             Solder paste applied! (after quite a few attempts)                                    Now put the IMU on the right position. (pad size = 0.2mm)

                            Baking in the reflow oven.

Assembly

     This is not the final version. But the idea is exactly the same.

Testing Setup 

Include photos, movies, CAD and animations here.

Build this site up during the project so you include early concepts and show how they progress.

Most recent material should be towards the top of this page.

Include a copy of the images used on the front page here as well.

Provide captions for each figure

Also, upload high resolution photos and CAD images in High Res. These files should be available for publicity events where high quality printouts or web images are needed.
