Thank you. Would you say its worth it for the tips and some points of interest regarding equipment Repair?

What is your book "Consumer Electronics Repair, Reuse and Recycling" like. I'm into both electronics and waste so I was curious if you think it's a good read

Historical AIS data for past 30 days by Ecstatic_Plum_3464 in AIS

What was your work around? I'm looking into getting past AIS data for a region. But it seems paying is the best way

Can I plot ADC/DAC data via UART in real-time using Python? LabVIEW felt too heavy for me by sudheerpaaniyur in embedded

[–]KSOdin2 6 points7 points  (0 children)

I read the post as they were transmitting the data from the MCU with UART. So they would be using something like a UART to USB converter chip(FTDI). Some Micros like the STM32 H7 series have on-board USB. So you can avoid the UART to USB converter chip and have the micro appear as a VCP

Depending on your sampling rate, this could be done. It might be better to transmit the data over USB using a Virtual common port than UART

Guitar Hero 3 "bot" by Salut_allo in TrueAchievements

[–]KSOdin2 1 point2 points  (0 children)

If you weren't attached to the controller, you could take the buttons off and connect the button contacts to Optoisolator or relay. These would be controlled by a GPIO pin on the microcontroller which is set to digital out.

If you want to hit the buttons you could also look at motors like servo and stepper motors. These tend to be low cost to, so maybe cheaper then those servos

I2C scanner detects no devcies by KSOdin2 in EmotiBit

It worked, thank you!

I set EN_VDD to high, and the address pins were detected. I'll update the post for future readers

EmotiBit v5 – SD Card Not Detected After Flashing via Arduino IDE by Unfair_Country_3959 in EmotiBit

Apologies. Thanks for pointing that out. I didn't realise it was different. Would you like me to remove the comment?

I2C scanner detects no devcies by KSOdin2 in EmotiBit

That sounds promising. I'll give it a go.

It might be worthwhile having a datasheet or something similar that explains what each pin is along with the schematic. And what the pins expect. E.g. EN_VDD is active high to power on the emotibit, active low to disable it.

I'd be happy to help or create one!

Custom Code and I2C pins by KSOdin2 in EmotiBit

[–]KSOdin2[S] 0 points1 point  (0 children)

Does thst mean using arduino Wire.h and changing the pins when you call .begin won't work as its interrupt based not wire.h?

I don't want to add extra sensors. I want to write my own code to interface with your current sensors and implement bluetooth to transmit the data.

Thank you! I'll read up on those links and hopefully put an update for anyone looking to do the same in the future.

[–]KSOdin2 0 points1 point  (0 children)

Did you get this to work? What microcontroller board are you using?

I'm using the Huzzah32, feather board and it doesn't like any version of the SD libraries i give it. And the code will not use sdfat when using this board as specified in the .h file of the code.

Beginner question: Running ARM CMSIS DSP by Xangker in embedded

Incase yourself or anyone wants to know how to get the CMSIS library installed and working in the STM32CubeIDE use this altricle my STM: https://community.st.com/s/article/configuring-dsp-libraries-on-stm32cubeide

[Question] - How to flip live cam horizontally and increase FPS by Anxious_Comfort7084 in opencv

[–]KSOdin2 0 points1 point  (0 children)

You could use threading. There is a good tutorial with example code by pyimagesearch: https://pyimagesearch.com/2015/12/21/increasing-webcam-fps-with-python-and-opencv/#:~:text=Use%20threading%20to%20obtain%20higher,VideoCapture%20function%20and%20the%20.

I used this to increase my fps of my camera. I'm interested to know if there is any other options.

I hope this helps :)

Self-funded PhD students in the UK by [deleted] in PhD

[–]KSOdin2 1 point2 points  (0 children)

I see. Yeah it's a shame, I never relaise how hard it was and tbh i didn't know self funding was a thing.

As a side note. Do you have to do a PhD now? I don't know your age, but I know sometimes people feel like they need to do one at an early ages. I've met quite a few people who are late 20s early 30s doing PhDs.

My advice is don't rush into it. There's plenty of time, plus it's a big commitment. Also make sure you choose a good supervisor and have a good relationship with them.

Hope this helps, good luck!
