I know this take has been done a million times, but like…computing and electronics are really, truly, unquestionably, real-life magic.
Electricity itself is an energy field that we manipulate to suit our needs, provided by universal forces that until relatively recently were far beyond our understanding. In many ways it still is.
The fact that this universal force can be translated into heat or motion, and that we've found ways to manipulate these things, is already astonishing. But it gets more arcane.
LEDs work by creating a differential in electron energy levels between—checks notes—ah, yes, SUPER SPECIFIC CRYSTALS. Different types of crystals put off different wavelengths and amounts of light. Hell, blue LEDs weren't even commercially viable until the 90's because of how specific and finicky the methods and materials required were to use. So to summarize: LEDs are a contained Light spell that works by running this universal energy through crystals in a specific way.
Then we get to computers. which are miraculous for a number of reasons. But I'd like to draw your attention specifically to what the silicon die of a microprocessor looks like:

Are you seeing what I'm seeing? Let me share some things I feel are kinda similar looking:
Tumblr media Tumblr media
We're putting magic inscriptions in stone to provide very specific channels for this world energy to flow through. We then communicate into these stones using arcane "programming" languages as a means of making them think, communicate, and store information for us.
We have robots, automatons, using this energy as a means of rudimentarily understanding the world and interacting with it. We're moving earth and creating automatons, having them perform everything from manufacturing (often of other magic items) to warfare.
And we've found ways to manipulate this "electrical" energy field to transmit power through the "photonic" field. I already mentioned LEDs, but now I'm talking radio waves, long-distance communication warping and generating invisible light to send messages to each other. This is just straight-up telepathy, only using magic items instead of our brains.
And lasers. Fucking lasers. We know how to harness these same two energies to create directed energy beams powerful enough to slice through materials without so much as touching them.
We're using crystals, magic inscriptions, and languages only understood by a select few, all interfacing with a universal field of energy that we harness through alchemical means.
Electricity is magic. Computation is wizardry. Come delve into the arcane with me.

you have 7+ computers ? ? i am so curious about the uses for them o_o
linux:
drawing laptop
older laptop w shitty battery
mini PC i use to clone a bunch of laptops in my home office (work related)
windows
work laptop
gaming PC/general use
old art mini PC, i don't rly use this much bc drawing worked nicer on Linux and I'm on hiatus w music for the foreseeable future
mini PC mounted to the ceiling by a projector in the living room, for movie nights n stuff :3 this is the one that could be moved to Linux

Bro, I hate to say this but sometimes things that aren't connected to the internet also need firmware updates!
My server room's AC has a bug where it won't start cooling if the room temp goes too far below the set-point of the AC and then goes back up above the set point again. Its a repeatable bug (reboot it fixes the setpoint, turn down the AC until it activates ALSO fixes the setpoint.) I'd do something other than complain about this on tumblr if I could update! the! firmware!

Understanding ESP32 Pin Configuration: A Developer's Guide
The ESP32 microcontroller has become a cornerstone of IoT development, thanks to its versatility and powerful features. One of the most crucial aspects of working with ESP32 is understanding its pin configuration and capabilities. Let's dive into the essential aspects of ESP32 pins that every developer should know.
Tumblr media
GPIO Pins Overview
The ESP32 boasts up to 34 GPIO (General Purpose Input/Output) pins, but not all are available for use in most development boards. Some key points about ESP32 pins:
GPIO 6-11: Reserved for internal SPI flash connection
GPIO 34-39: Input-only pins with no internal pull-up/pull-down resistors
ADC Capabilities: Two 12-bit SAR ADCs, supporting 18 measurement channels
Touch Sensors: Up to 10 capacitive touch GPIOs
Special Function Pins
Several pins serve dual purposes or have specific functions:
Boot Mode Pins GPIO 0: Bootloader mode when pulled low during reset GPIO 2: Connected to on-board LED in many development boards
UART Pins GPIO 1 (TX) and GPIO 3 (RX): Default UART0 communication Often used for flashing and debugging
SPI Pins VSPI: GPIO 5 (CS), 18 (CLK), 19 (MISO), 23 (MOSI) HSPI: GPIO 14 (CLK), 12 (MISO), 13 (MOSI), 15 (CS)
Best Practices for Pin Usage
Strapping Pins Always check the strapping pin status before using GPIO 0, 2, 4, 5, 12, and 15. These pins may affect boot behavior if incorrectly configured.
Input-Only Pins When designing sensor interfaces, prefer GPIO 34-39 for analog inputs as they're input-only and less susceptible to noise.
Pull-up/Pull-down Configuration
ADC Usage ADC1: Can be used with Wi-Fi/Bluetooth active ADC2: Only available when Wi-Fi/Bluetooth is disabled
Common Pitfalls to Avoid
Don't use GPIO 6-11 in your projects as they're connected to the internal SPI flash.
Avoid using strapping pins for critical functions that can't be changed during boot.
Remember that GPIO 34-39 don't have internal pull-up/pull-down resistors.
Be cautious with voltage levels - ESP32 pins operate at 3.3V.
Conclusion
Understanding ESP32 pinout is fundamental for successful project development. By following these guidelines and best practices, you can avoid common issues and make the most of your ESP32's capabilities. Remember to always consult the official ESP32 technical reference manual for detailed specifications and updates.

Understanding Embedded Computing Systems and their Role in the Modern World
Embedded systems are specialized computer systems designed to perform dedicated functions within larger mechanical or electrical systems. Unlike general-purpose computers like laptops and desktop PCs, embedded systems are designed to operate on specific tasks and are not easily reprogrammable for other uses. Embedded System Hardware At the core of any embedded system is a microcontroller or microprocessor chip that acts as the processing brain. This chip contains the CPU along with RAM, ROM, I/O ports and other components integrated onto a single chip. Peripherals like sensors, displays, network ports etc. are connected to the microcontroller through its input/output ports. Embedded systems also contain supporting hardware like power supply circuits, timing crystal oscillators etc. Operating Systems for Embedded Devices While general purpose computers run full featured operating systems like Windows, Linux or MacOS, embedded systems commonly use specialized Real Time Operating Systems (RTOS). RTOS are lean and efficient kernels optimized for real-time processing with minimal overhead. Popular RTOS include FreeRTOS, QNX, VxWorks etc. Some simple devices run without an OS, accessing hardware directly via initialization code. Programming Embedded Systems Embedded Computing System are programmed using low level languages like C and C++ for maximum efficiency and control over hardware. Assembler language is also used in some applications. Programmers need expertise in Microcontroller architecture, peripherals, memory management etc. Tools include compilers, linkers, simulators and debuggers tailored for embedded development. Applications of Embedded Computing Embedded systems have revolutionized various industries by bringing intelligence and connectivity to everyday devices.
