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.

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

1. Adruino 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:

• Adruino 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.

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.

The following parts were purchased by Raw scientist:

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

Raw scientist has achieved partial radio communication.

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

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!

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.

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.

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.

The following parts were bought by Raw scientist today:

1. Lithium Ion cell × 3 = ₹320
2. Load cell = ₹120
3. Load cell module = ₹55
4. XP Connector (ESP) = ₹20

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

3S 25 Ampere Battery Management System was bought by SC for 150/- INR. in cash.

To start making the VTOL frame, Raw scientist has bought PVC pipes worth 50/- INR.
