Scinece fiction isn’t always about the future. Sometimes science fiction elements are meant as metaphors for the human experience. William, Burroughs imatined the cyberspace as a metaphor for memory in his seminal novel Neuromancer. 1984 was as much a warning as it was an analysis of contemporary political situatons. And Sherwood Anderson’s “Famine on Mars” was all about the depression. Here’s more from Science Fiction and More Ruminations:

Simultaneously drawing on the rise of fascism in Europe, Kelly’s “Famine on Mars” creates an even more draconian governmental manifestation. Earth’s government, The Combine, acts as a genocidal and malevolent political entity that brainwashes its inhabitants in the name of “the brotherhood of man” (79). His use of “combine” evokes two interrelated images of monolithic and mechanical power: new 1920s harvesters pulled by tractors instead of mules and a combination of both political and economic powers. Like a new-fangled tractor-driven thresher, the Combine mechanizes society diminishing its human concerns. Kelly suggests the working class in this future receive numerical names while political elite received standard nomenclature.

If you love the vibe of vintage Macs but want something a little more practical then this project is for you. MechaNickW was inspired by Pi Day to update is old Macintosh with a Raspberry Pi, a small HDMI screen and a few other bits.

Via MechaNickW on Instructables:

I was lucky enough to have someone give me a working vintage Apple Macintosh SE several years ago. They are neat machines, and were around when I was very young so somewhat nostalgic for me. While it was fun to have one, it’s not a very useful computer in the modern age. I’d wanted to integrate a Raspberry Pi into the plastic enclosure as a desktop machine for my electronics bench for years, and was inspired by Pi Day and the Instructables contest to finally make my dream of an Apple Raspberry Pi come true as a Pi Day celebration!

NEW PRODUCT – Pimoroni Pico Plus 2 – RP2350 Dev Board with Pico Shape and Pins – PIM724


The Pimoroni Pico Plus 2 is a top of the line Pirate-brand RP2350 microcontroller with 16MB of flash memory, 8MB of PSRAM, USB-C, Qw/ST, and debug connectors. It’s an excellent ‘drop in’ upgrade to the classic Pico 2 when you need MOAR power and memory.

We adore the versatility and value of Raspberry Pi Pico 2, but we also enjoy a souped-up RP2350 board with all the extras baked in. The team at Pimoroni crammed in as much extra functionality as they possibly could whilst keeping to the original Pico footprint to maintain compatibility with existing Pico add-ons.

Check out our collection of PiCowbells for ways to extend/expand your Pico Plus’s hardware capabilities

Pimoroni Pico Plus 2 has the same shape and pinout as the classic Pico 2 but with the ‘B variant of the RP2350 which lets them shoehorn in so much more:

  • powered and programmable via USB-C
  • comes with an upgraded 8MB PSRAM
  • 16MB of flash storage
  • Easy-to-read pin labels. It’s super easy to connect up to things without soldering
  • Qwiic/Stemma connector (for adding I2C sensors and breakouts via cable)
  • SP/CE connector (for hooking up SPI/serial devices via cable)
  • JST-SH Debug connector (for if you like to program using a SWD debugger)
  • Reset button (luxury!)
  • BOOT button, which can also be used as a user switch.

When I was young I broke my arm, as many do at that age; I immediately got the plaster cast wet at a birthday party, as many do at that age. I had to take ANOTHER trip to the doctor for a new cast to be set costing time, money, and wear and tear on my parents. Diana Hall created the company ActiveArmor to supply activity approved 3D printed casts.

Profile from Joan Horvath on Make:

To create each custom cast, first a scan is made of the patient’s injured body part, using ActivArmor’s phone app. Then the device is created by an ActivArmor provider using the company’s proprietary software, which has been a crucial invention. The cast can be locked on, or not, depending on whether the patient is allowed to remove it.

The material has to be not just biocompatible but also non-porous, so that customers can bathe, swim, and live fairly normally, versus a traditional cast that can’t get wet. To accomplish that, the casts need to be post-processed to remove layer lines. If you’re a 3D printing person, you know that the conditions in the room and even the batch of filament can affect the outcome, so ActivArmor and its providers need to manage those variables. And there are more issues in the case of a cast, such as transparency to X-rays.

NEW PRODUCT – Adafruit Metro RP2350 with PSRAM


Choo! Choo! This is the RP2350 Metro Line, making all station stops at “Dual Cortex M33 mountain”, “528K RAM round-about” and “16 Megabytes of Flash town” and a bonus stop at “8 Megabytes of PSRAM village”. This train is piled high with hardware that complements the Raspberry Pi RP2350 chip to make it an excellent development board for projects that want Arduino-shape-compatibility or just need the extra space and debugging ports.

  • RP2350 main chip, 150MHz clock, 3.3V logic
  • 16 MB of QSPI Flash for program storage
  • 8 MB of QSPI PSRAM for extra dynamic memory
  • 37 Available GPIO: 23 on the socket/SPI headers, 12 on HSTX port, and another 2 for USB host. 6 of which are also analog inputs
  • Micro SD card socket wired up for SPI interfacing, also has extra pins connected for advanced-user SDIO interfacing (note that there’s no code for SDIO in Arduino/Python, so this is a super-cutting-edge setup)
  • 5V Buck Converter featuring TPS563201 6~17V DC input and up to 2A output
  • Onboard RGB NeoPixel
  • Onboard #23 LED
  • Stemma QT port for I2C peripherals and sensors
  • 22-pin 3-lane differential HSTX FPC port with ‘Pi 5’ compatible pinout, makes for quick DVI video output. Or, this also provides 12 extra GPIO that can be used for more pins.
  • Reset and Boot buttons on PCB edge
  • Pico Probe debug port – 3 pin JST SH compatible
  • USB Type C power and data
  • 5.5mm / 2.1mm DC jack for 6-17VDC power
  • On/off switch for DC jack
  • RX / TX switch for swapping D0 and D1 locations
  • USB Host breakout pads – with controllable 5V power and D+/D- for bitbang USB Host.
  • GPIO pin numbers match classic Arduino pins, other than GPIO 12 and 13 as those are needed for HSTX connectivity

You may be wondering about the RX-TX switch: we added this because traditional Arduino board start counting the GPIO for the digital pins with 0-7 and then 8-13. However, the D0/D1 pins are also traditionally the hardware UART Serial1, where D0 is Rx and D1 is Tx. On the RP2350, however, the UART pins are the other around: D0 is Tx and D1 is Rx. Thus a DPDT switch: flip one way to have the GPIO go in order of 0-7, flip the other way to have the logical locations of the hardware UART correct but now the pin order is 1, 0, 2, 3..7. Of course, it’s also handy if, like us, you often swap the pins – now you don’t need to require or cut/solder traces!

Inside the RP2350 is a ‘permanent ROM’ USB UF2 bootloader. What that means is when you want to program new firmware, you can hold down the BOOTSEL button while plugging it into USB (or pulling down the RUN/Reset pin to ground) and it will appear as a USB disk drive you can drag the firmware onto. Folks who have been using Adafruit products will find this very familiar – we use the technique on all our native-USB boards. Just note you don’t double-click reset instead hold down BOOTSEL during boot to enter the bootloader!

There is great C/C++ supportunofficial (but really good) Arduino support, an official MicroPython port, and a CircuitPython port! We of course recommend CircuitPython because we think it’s the easiest way to get started and it has support with most of our drivers, displays, sensors, and more, supported out of the box so you can follow along with our CircuitPython projects and tutorials.

While the RP2350 has lots of onboard RAM, it does not have built-in FLASH memory. Instead, that is provided by the external QSPI flash chip. On this board there is 16 MB, which is shared between the program it’s running and any file storage used by MicroPython or CircuitPython. When using C/C++ you get the whole flash memory, if using Python you will have about 14 MB remaining for code, files, images, fonts, etc.

RP2350 Chip features:

  • Dual ARM Cortex-M33 with floating point unit or Dual RISC-V @ 150MHz
  • 520 kB on-chip SRAM
  • 8 kB of one-time-programmable (OTP) memory.
  • Support for up to 16MB of off-chip Flash memory via dedicated QSPI bus
  • Support for external QSPI PSRAM
  • DMA controller, 16 channel, 4 IRQ
  • Fully-connected AHB crossbar
  • On-chip switched-mode power supply and programmable low-dropout regulator (LDO) to generate core voltage
  • Two on-chip PLLs to generate 48 MHz USB and 150MHz core clocks
  • Optional boot signing with protected OTP storage
  • Hardware SHA-256 accelerator
  • Hardware random number generator (TRNG)
  • 48 GPIO pins, 8 of which can be used as analog inputs
  • Peripherals
    • 2 UARTs
    • 2 SPI controllers
    • 2 I2C controllers
    • 24 PWM channels (compared to 16 on RP2040)
    • USB 1.1 controller and PHY, with host and device support
    • 12 PIO state machines

Please note: The Adafruit Metro RP2350 comes with the A2 version of the RP2350, which is affected by the E9 erratum. This errata affects some uses of GPIO and PIO such as high-impedance inputs and the internal pulldowns. You may need to use 8.2K or smaller resistors if pull-downs are required. At this time, Feb 2025, there is no other version of the RP2350 available – only the A2 version.
