Making 32 bespoke hand crafted bits.

Hand made bits are so much nicer than store-bought bits.

In the early days of woven core memory they sent it off to women to weave because the dudes took one look at it and thought “this is girl stuff like sewing and weaving”

I find this hilarious.

Here is a link (cued to the time where it starts) of the best and most clear explanation of how core memory works. Reading & writing a bit has many steps!

I always felt there was something poetic about how one must destroy this kind of memory in order to read it. Observation is never passive... to observe a system is to change it...

HALLOWEEN - Kiddo Robot Pt 1.

We're all going to be robots.

Kiddo wants something on his chest (like Iron Man) and something that makes robot noises. Had this LOL Shield (remember them?) from YEARS ago. Going to invest learning and doing new things in other aspects of our costumes. Wired-up a switch and battery pack. Using the DNA Spectrum Sketch. Just need a cardboard assembly, silver spray paint, and onto the next.

Arduino Due vs. Mega: A Comprehensive Comparison

What is Arduino Due and Mega?

The Arduino platform has revolutionized the world of DIY electronics, providing hobbyists and professionals alike with versatile and powerful microcontroller boards. Among the myriad of options, the Arduino Due and Arduino Mega stand out for their advanced features and robust performance. The Arduino Due, introduced in 2012, is the first Arduino board based on a 32-bit ARM core microcontroller, the Atmel SAM3X8E. In contrast, the Arduino Mega, built around the 8-bit ATmega2560 microcontroller, is known for its abundant I/O pins and memory. Understanding the differences between these two boards can help in selecting the right one for specific projects, enhancing both functionality and efficiency.

Processing Power and Performance

The processing capabilities of the Arduino Due and Mega are distinctly different, primarily due to their core microcontrollers. The Arduino Due, with its 32-bit ARM Cortex-M3 processor running at 84 MHz, offers significantly higher processing power compared to the Arduino Mega's 8-bit ATmega2560, which operates at 16 MHz. This difference in architecture and clock speed means that the Due can handle more complex calculations and tasks faster and more efficiently than the Mega. For projects requiring high computational power, such as real-time data processing or handling multiple sensors simultaneously, the Due is the superior choice. However, for simpler tasks, the Mega's processing power may suffice.

Memory and Storage Capabilities

Memory is another critical aspect where the Arduino Due and Mega diverge. The Arduino Due is equipped with 512 KB of flash memory for code storage and 96 KB of SRAM for data. On the other hand, the Arduino Mega has 256 KB of flash memory and 8 KB of SRAM. Additionally, the Due features a Direct Memory Access (DMA) controller, which allows for efficient memory operations, freeing up the CPU to handle other tasks. These memory enhancements make the Due more suitable for applications requiring large codebases and significant data handling, such as advanced robotics or sophisticated control systems. The Mega, with its more modest memory, is ideal for less demanding applications.

Input/Output Capabilities and Expansion

Both the Arduino Due and Mega are renowned for their extensive input/output (I/O) capabilities, yet they cater to different needs. The Mega boasts a whopping 54 digital I/O pins, 16 analog inputs, and 4 UARTs, making it ideal for projects that require multiple sensors, actuators, or communication interfaces. The Due, while offering fewer digital I/O pins at 54, includes 12 analog inputs and 4 UARTs, along with additional features like two DAC outputs for analog signal generation and enhanced PWM capabilities. These features provide the Due with superior analog output capabilities, making it suitable for applications like audio processing or advanced signal generation.

Power Consumption and Compatibility

Power consumption and compatibility are practical considerations when choosing between the Arduino Due and Mega. The Due operates at 3.3V logic levels, which makes it more power-efficient than the Mega, which uses 5V logic levels. This lower voltage operation is beneficial for battery-powered projects where energy efficiency is crucial. However, the 3.3V logic also means that the Due is not directly compatible with 5V components without level shifters. The Mega, with its 5V logic, offers broader compatibility with existing Arduino shields and components, making it a versatile choice for a wide range of projects. Understanding these power and compatibility nuances can help in making an informed decision based on the project's specific requirements.
