Science is amazing

To think that we've been for 3.3 million years, and even more, going from stones spears to intelligent computational stones in around 500 years (the invention of the scientific method) is impressively elegant.

We've como so far we are understanding how the universe itself works.

But then you say, "theres still a lot we dont know"

But, think it on another way. A 100 years ago, there were things we tought we couldn't understand.

But whe did it anyways.

If the theory of the Big bounce is real, then the universe resets every time and let's us try again.

But, you could think the universe is fully deterministic and everything would happen exactly as it is now, but it isnt. At the cuantum level, everything is random.

And, thanks to the butterfly effect, a small change, like the position of an atom, could change the weather of earth, make everything slightly different.

We have proven that not everything is truly random, but quantum physics says otherwise.

But, as we always do, we will discover everything.

We will get every secret of the universe, some day, just like senku did.

And even if we dont, the universe will reset, maybe thousand of times until we figure out everything.

Life is truly incredible

This is a PCM synthesizer i've been working on for the past 5 months for the cardputer ADV, its been an interesting journey, i made everything from the ground up, the audio library, menu library, file type, etc.

song : You've got mail! by phantoskii , check her out in youtube

Any software that allows for making .WAV loop points and store them properly in the smpl riff header?

Ive tried audacity, and ocenaudio, but none of them export the loop points.

The only tool that worked was Wavosaur, but Its only on windows.

PCM-MCU-C Version 3.0 (SF2 support)! - Python utility for converting audio files to: .h .pcm .spack

Ever wanted to play audio on your arduino embedded proyect using a .h file, but the converters require too many steps?
well, not anymore.
My python utility handles everything for you using ffmpeg-python and numpy, allowing for in place conversion, drop your audio at /input and get it at /output, you can tweak the bit depth, sample rate and padding for .spack files!

With the release of V3.0 of PCM-MCU-C, the app is much more stable due to the usage of my new libary: MenuCLI, and also with the adition of converting .sf2 files directly.

WARNING FOR DEVELOPERS REGARDING CORE 0

I was breaking my head over a problem for 3 days, i optimized everything, but my RTOS task was still slow.

Until, i designed to swap over from core 0 to core 1.

I tought it seemed counter intuitive because program runs at core 1.

And that i correct, but tasks on core 0 run much slower than on core 1.

And, my assumption would be that the M5Stack library uses core 0 for SPI, stuff like sd card, screen, speaker, etc.

So watch out, if your RTOS task is weirdly slow, then change the core to 1.

Also, is thus assumption correct?

CardMera - effect showcase

As of now i have these effects (could be more but im lazy)

Flip endian

Bleed (bleeds color data)

Flip RB

RB mask (just makes everything red lol)

I have a layer system and strength, so you can use multiple effects and use them as you like.

For example, if you do Flip endia twice it looks normal, but you can put another effect btween it and archive some nice effects

Cardmera Alpha V0.10

https://github.com/Mejolov24/Cardmera

Turn your cardputer a pocket camera with an ESP32-CAM.

This is an alpha release, you can only takes photos up to around 1920x1080, sincei need to implement double buffering.

Also, video isnt implemented yet.

But I tought it would be nice to make a mini release before i work on my other proyects.

Only works on Cardpuer ADV, but can be ported, I would just need to change the serial ports to use grove port and add keyboard support for normal cardputer

I cant post a photo because reddit thinks my post is spicy and deletes it for some weird reason

Testing the camera i made

The first photo is also taken with it, its just that when i apply effects, they need to be captured as a screenshot due to hardware limitation

I booted onto windows to get some files. My fans didint turn on. Took me 5 minutes until my cpu became an esp32 😂

Im making a camera, but i never had one. Help me define the keybinds

The device shown in the photo is a cardputer, i attatched a camera module to it.

These are all the avalible settings:

  • Flash
  • Brightness
  • Contrast
  • Saturation
  • Sharpness
  • Auto White Balance
  • White Balance Mode
  • Auto WB Gain
  • Auto Exposure
  • Exposure Bias
  • Exposure Speed
  • Enhanced Exposure
  • Auto Gain
  • Manual Gain
  • Gain Ceiling
  • Denoise
  • Lens Correction
  • Mirror Image
  • Flip Image
  • Color Effect

to what keys should i assing them?
and, wich ones should be in the UI?
They are all avalible at pro settings but not as quick actions
For obvious reasons flash is already added as a quick button, but im unsure wheter its good or not (toggles with "esc").

EDIT: I know cameras dont have a keyboard. But, what settings do cameras usually have a button for?

Somewhow it works (tried to move an smd component, didint realise the solder was going somewhere else)

I managed to finish the job, and "everything" work with no issues so far.

Actually it was ging excellent at first, I desoldered the smd resistor, and then i somehow lost it, so i soldered a small wire that kept sticking due to surface tension and kept acumulating solder.

Quite horrible, im never soldering smd without proper equipment.
