putting dicts in post requests for data in micropython doesn't work

I'm trying to access the Geometry Dash severs from my Raspberry Pi Pico W but I need to pass data={"secret":"Wmfd2893gb7", "str":"RobTop"}. However when passing dicts, it gives me this error.

Traceback (most recent call last):
  File "<stdin>", line 27, in <module>
  File "requests/__init__.py", line 184, in post
  File "requests/__init__.py", line 123, in request
TypeError: object with buffer protocol required

This is my code snippet

py
data_dict = {
        "secret":"Wmfd2893gb7",
        "str":"RobTop"
        }
res = urequests.post(" https://www.boomlings.com/database/getGJUsers20.php ", headers={"User-Agent":""}, data=data_dict).text
print(res)

Recommended Apps (error fetching while offline)

Hi there! I seem to be having difficulty getting my cyberdeck loaded Pi to load up the recommended apps. when I run status NetworkManager.service I did notice that it's kicking out Error/Warn messages, would that have something to do with it? (couldn't initialize supplicant interface 2/3/4/5)

PiKiss Dolphin not working and other things.

I tried to get Dolphin on PiKiss and it said it downloaded successfully and i can see that it had downloaded the necessary files except the dolphin-emu part which is weird because the rest downloaded. I don't have a 5V power supply but i don't think this is the issue. Other games also don't work like half life and fallout 2. Fallout said it didn't have the right text font. Please help

how do i connect different sensors to my raspberry pi zero w without soldering

I wanted to create an accident detection sensor wherein the raspi would read data from the accelerometer(mpu6050), gps(neo6m) and then notify the registered mobile number using the gsm module(sim800l) in case of an accident All the other sensors came with headers except for the raspi and there isnt enough time/funds to go buy the headers for the raspberry so i was wondering is there any way i can connect the raspi to the sensors using male to female jumper wires without soldering Maybe by using breadboard Im new to soldering so i dont want to accidentally damage the board Would also appreciate it if you can help me assemble the project by giving some basic advice

Raspberry Pi Zero 2 W not booting

I have a 02W and the only OS so far it will work with is Raspian Bullseye 32-Bit, but I want something more up-to date. Both 32 and 64 bit versions of bookworm doesn't do anything past the rainbow screen and the logo (it just goes black). It doesn't show up on my wifi either so I can't SSH in despite setting networking and SSH up in the official imager. What do I do?

Pico stuck on bootloader?!

Hello everyone! I have a Raspberry pi Pico and I was trying to connect it to a QTR-8RC sensor (IR sensor array). Anyways, I got some code online for the arduino ide, it used a library called QTR sensors from Polulu (manufcater of the sensor), and when I uploaded to the pico as I usually do it crashes midway and I can't seem to get it connected to the pc properly (doesn't get allocated to a port). Then I tried to do flash_nuke.uf2 and now I'm stuck in the bootloader... Windows 11, no cable problems, same test in 2 picos. Thank you in advance

school project on Pi

I need a school project on my pi due tuesday next week. Just something software based. Im not really into linux and would like to have a good idea or even a finished project. I originally wanted to make the pi into my own acces point and use pi hole on it. But it didnt work. Maybe someone could help me doing this i keep running into problems over and over again. I need a very strict tutorial tho, something like "configure program xy to be it the Standard for application z" is already to hard for me. Just an impressive cool looking project but not the hardest to do would be cool<:babyblob:1053364680200044564> thx

Desperately need help with xScreensaver

Can anyone help? I have a Raspberry Pi 3 with Bullseye OS installed. Cant seem to find a definitive way to install it and get it working? I work for a small charity and all we want is a slideshow of images playing on our TV in the window on a loop. I've tried LibreOffice Impress but it seems to cause no end of problems for the Pi. I guess because it cant handle the graphics? Thanks so much!

Help w/ kernel panic after 2nd startup (Pi 3B+)

I have tried booting up with with different images on different SDs (including latest Raspbian), but they all seem to freeze at the first startup, and print out some flavour of kernel panic on the 2nd. Is my board gone for good? Or is there anything I can try to fix this? Thanks!

Pull up resistors

Greetings. I am currently using chatGPT to assist programing with my scrollwheel project. In this project I am using 2 photo sensors (EE-SX461-P11) to create scroll wheel functions up and down. I've rewired the board a few times. Both sensors work fine independently, but when they're wired together on the same board they have difficulty working fully correctly. They can work, but not as well. I need help with pull up resisotrs. I have no idea where they're supposed to be placed for the circuit to work correctly. Any help is greatly appreciated. Dupp.

LED not dying without resistor

Hi! I have a quick question regarding LEDs. My understanding has been that whenever using an LED I should use it in combination with a resistor to limit the current. I have a bunch of different coloured LEDs and have noticed (accidentally) that when I wire up a blue LED directly to 5V, with no resistor, it seems to work fine. A yellow or green LED for examples dies effective immediately. What could explain the blue LED not dying? For reference the 5V source I'm using is a 65 watt capable USB PD power supply at 5V.

enabling Samba shares on Pi 5

okay, so...I'm trying to make it so that I can access my pi remotely from Windows because I'm trying to add all my games back on there that I backed up from my Pi 3B... however since I don't know what I'm doing, I got it working once I installed Samba and now I've locked myself out again... what is happening? I would just use Ubuntu and add the games that way but Ubuntu, when booted from a USB stick, keeps freezing up, my USB ports, my screen, everything, and I have to use the power switch to turn it off

connecting Motors to motor drivers

Hi all, so i am working on a little project which involves a robot chassis that comes with 4 wheels and motors.The name of the chassis is called Robot Chassis Kit NP and here is direct link for you to see https://thepihut.com/products/robot-cha ... 1900217539. I am very new to robotics and raspberry pi in general so i did struggle a lot.The motor drivers i am using is called the Pololu DRV8835 Dual Motor Driver Kit for Raspberry Pi. https://thepihut.com/products/pololu-dr ... 4113612995. I bought two of them because i was told i needed two run all four wheels, however, from this point i faced lot of issues, as i didn't realise i wouldn't have to solder parts like the female header and terminal headers which was long and difficult because i didn't know how to solder,but managed to.The real issue is the actually connecting the motor drivers to the motors, the motors come with this JST connector with this white paper clip but i didnt know or understand how this would fit into the blue terminals shown in the video demo, i then cut the paper clip of the JST connector like this.https://imgur.com/a/qjcZqGL i couldn't show actual image because it was saying it was too large, but as u can see i cut it of.I connected my motor drive to the grove base hat for raspberry pi https://thepihut.com/products/grove-bas ... 0299200707 to my raspberry pi 4b model, like this i'm not even if this correctly setup but here.https://imgur.com/a/omPlJ9h . If anyone could give me any tips, suggestions or advice on how to correctly set this up, id really appreciate it as i have struggled
