 ## Feedback from Bas and Henk
 I've gotten some feedback on my design and about the use of screens. Maybe I should only use speakers or use LED matrixes. After thinking about it I think im going to give LED matrixes a spin.
 
-## CAM and machines
+## Drone electronics
+For the drone I will need a lot of electronics. But I will also need a pcb for inside the drone so I don't have any loose connections. The main board needs a couple of components. Something to step down the voltage from the big battery or I will use two separate batteries one for the motors one for the control board. I will also need a sensor to know the position of the drone and a microcontroller. I also need a lot of power to power the screens so that will also be something interesting.
+
+### Components 
+* MCU
+* BNO085
+* Something to drive the LED matrixes
+* SD card/ secondary MCU to control the matrixes
+* LED (mandatory)
+
+### Drone remote electronics
+I'm also building the remote for the drone
+
+* Potslider for the throttle
+* Joystick for left-right-forward-backwards
+* battery
+* screen to see status of drone
+* LED (mandatory)
+
+#### Joystick
+I really wanna use a joystick for this project because having 2 potmeters under each other looks a bit weird.
+
+### KiCad
+The first thing I did was import the design rules for our milling machine. I used the file from the lecture to import it from because there we set everything up together.

+
+Now im going to grab all the components needed for the board
+* [Joystick](https://www.digikey.nl/nl/products/detail/c-k/THB001P/11687191) x2
+* LED
+* small oled screen
+* xiao espS3
+
+
+I was struggling a lot when thinking on how to connect the joysticks because the data sheet says it needs 5 volts. Until I realized they where potentiometers and they should work with any voltage. So I could directly connect the Joysticks to the MCU
+
+Instead of it looking like this.
+

+This configuration wouldn't have worked anyway because the voltage regulator forces the voltage to 3.3 so the mcu will only read one value.
+It now looks like this:
+
+![alt text](image-2.jpg)
+So I have 2 joysticks that are directly connected to the mcu. A screen that works on the I2C protocol and a LED.
+
+First when routing the joysticks I realised that the Xiao has analog on both sides of the board. So if I change the schematic so it connects to the other side I have a lot less longer traces.
+
+![alt text](image-3.jpg)
+
+![alt text](image-4.jpg)
+So like this instead of needing them to go across the entire mcu.
+
+I forgot to apply the design rules so I imported them again and now I have to retrace everything. Thanks Irja for checking them together.
