Today transition mechanism and vertical to horizontal swivel mechanism was tested.

40(A) BMS for just was bought.

The following parts were purchased:

1. Arduino Nano
2. NRF24 with antenna
3. 2 Switches
4. Display
5. Resistors

The parts arrived and were mounted to the frame. The hop test will be conducted in the 2nd week of December.

The mount for the motors and to make the transition design, a 3d structure is ordered costing 320 INR for the whole order.

And he delivers. Raw Scientist does what he always does. Best soldering work, with clean and simple design. Check this out: Photos of the reciever module

The ordered parts are delivered and now the work of building the receiver pcb starts. The greatest solderer of all time Raw Scientist will now handle the task of putting all the parts together.

Raw Scientist Calibrated the gyroscopic system, which will help the vtol to be stable in mid air, and not lose its balance due to strong winds and other external factors. Now we are waiting for other parts to be delivered like: header pins, bigger servos and voltage regulator.

Raw Scientist made the battery and bms was integrated in it. The beasty power supply is ready to put on the frame.

Raw Scientist conducted a test by suspending the whole frame to a thread, and tested the motors. The model looked like a dragonfly. The frame looked quite disbalanced due to absence of gyros.

Raw Scientist changed the design by using a modified male-female joint mechanism. It was sturdy, and good to go forward.

The team met on sundays and made upgrades to the design, like trying new design for holding servos and motors, improving radio module and changing the whole body design. The team then tried modelling various transition mechanisms.

To start making the VTOL frame, PVC pipes were bought.

3S 25 Ampere Battery Management System was bought.

Raw scientist calculated the net thrust to be 600gms of one pair of thrusters. So we have around 600gms to play with!

The following parts were bought today:

1. Lithium Ion cell × 3
2. Load cell
3. Load cell module
4. XP Connector (ESP)

All the parts are now recieved. Raw scientist and SC tested all the parts. The propellors and the servos were all running fine. For the next steps a vc will be held tomorrow.

A vc was conducted today, the following parts were purchased:

1. SimonK 30A BLDC ESC Electronic Speed Controller with Connectors × 2
2. A2212 6T 2200KV Brushless Motor for Drone (Soldered Connector) × 2
3. SG90 Micro Servo Motor × 5
4. Quadcopter propellers 10 x 4.5 (1 Pair) × 2
5. Male to Female Jumper Wires (20cm) 40pcs × 1

The team will pay equal amounts.

A vc was conducted today, the topics discussed are:

• The problem with NRF24L01 module with antenaa: The modules of transmtitter and receiver were replaced, as the NRF24l01 module with antenna wasn't transmitting data.Raw scientist then swapped the module with SMD module with antenaa which was placed in the reciever.
• The purchase of BLDC motor: The team needs to contribute for the money which will be needed to buy the motors. In total 2 motors need to be purchased, and everyone will try and find motors with the required specs and budget.
• Design of the VTOL: NR and IVORY will be looking at the designing of the vtol as well as the marterial. They will collaborate with one another for the same.

Another vc will be held tomorrow to discuss the purchase of BLDC Motors.

Raw scientist with the help of NR's and SC's code has succesfully tested the working of servo. The transmitter is giving the instructions properly while the receiver is capturing the movements of the server and showing proper output. The servo was wirelessly controlled using NRF24L01!

Raw scientist and SC have achieved complete radio communication. They have successfully assembled transmitter module on PCB board!

Raw scientist has achieved partial radio communication.

The following parts were purchased by:

1. Data Cable (1)
2. NRF24L01 3.3v Adapter Module (2)
3. 100μF Capacitor (2)
4. 10μF Capacitor (2)
5. GPIO Header pin (8)

SC has completed the coding of transmitter. He has also completed testing of all the parts he had with him and performed tests by completing the circuit for transmitter.

Today 7 June SC, Raw scientist, IVORY went for shopping Parts bought today:

1. Arduino Nano (2)
2. NRF24 with antenna (1)
3. NRF24 without antenna (1)
4. Joystick module (2)
5. Port B to USB cable (1)

IVORY — Today at 10:58 PM: This is the bill of the above mentioned items which mentions the amount 810. The item 5. Port B to USB cable (1) is not mentioned as it was purchased after obtaining Microchip and cuz we didn't check while buying The cost of the item 5. Port B to USB cable (1) is 30/- INR. IVORY — Today at 11:06 PM: As of now SC will be testing a few parts from the above mentioned list which include:

• Arduino Nano (1)
• Joystick Module (1)
• Port B to USB cable (1)

Raw scientist has the remaining parts. He has posted a photo suggesting that the parts need to be cleaned up using "rubbing alcohol". I am "assuming" that he will be doing it by himself as I haven't received any update on it by him at the moment of writing this message.

From today's vc: NR is going to do movement control. A irl meeting is going to be conducted at Eren Jeager's house in the forthcoming days SC has completed the coding of reciever, and Raw scientist will be working on the design when he will return home. IVORY will be there to help you all. Till now No one has asked to But I am Here.
