Andrew Back posts about restoring a vintage Sun SPARCstation IPX workstation.

If you worked in computing in the early 1990s, studied computer science around then, or just had a keen interest in computers, the chances are that Sun Microsystems was a familiar name and their workstations were highly coveted.

At this time PCs were fast becoming the standard desktop computer and pretty much all looked the same, while if you worked in a creative industry you might have been lucky enough to use a Mac — but even then, the differences were not so profound

However, there was a breed of computer that really stood out from the rest and not only looked far more exotic, but had a clear lead in terms of performance and capabilities — the UNIX workstation.

While most people were running Windows 3.x and being frustrated at the limited resources, lack of true multitasking and all too frequent instability, UNIX workstations provided a far more advanced, feature rich and robust environment. This included proper multitasking and typically greater RAM, more powerful CPU and advanced graphics, plus higher performance disks etc. Of course, this all came at a cost and a UNIX workstation could easily have a price tag 10x that of a typical PC.

An AI powered robot roaming through crowds of tourists. What could go wrong?!

Ok so Olaf isn’t fully autonomous but it is waddling in that direction. A new roaming snowman animatronic is coming to Disney World of Frozen in Paris and Tokyo. The AI in this instance is primarily focused on walking movement and heat management.

Learn more from Fast Company:

But building a weird skeleton is useless if it can’t walk. To nail the specific, goofy gait of the character, human coding simply wasn’t enough. Disney turned to reinforcement learning, an artificial intelligence technique that works like an evolutionary sandbox. In a virtual simulation, the software was fed the exact animation files from Walt Disney Animation Studios and tasked with figuring out how to fire the motors to balance the heavy head and match those movements without real-world Olaf face-planting every few steps. Through relentless trial and error, the AI discovered the precise mathematical inputs needed.

The Orbigator is an open-source, physical satellite tracker that turns complex orbital mechanics into a desk-side companion. It is powered by the Raspberry Pi Pico 2 and precision DYNAMIXEL servos, it physically points to the ISS (or any satellite) in real-time with zero drift.

Continuous, Uninterrupted Motion

Unlike traditional trackers that use static globes (requiring wire unwinding every orbit), the Orbigator features a rotating globe. This allows for smooth, continuous tracking across multiple revolutions without ever needing to reset or “unwind.”

LVLH Attitude Control

The orbital mechanics are implemented directly in the hardware geometry (inclination angle). This ensures the satellite pointer maintains a true LVLH (Local Vertical, Local Horizontal) attitude throughout the entire pass—exactly how real satellites orient themselves.

Zero-Drift absolute Positioning

Leveraging the 32-bit absolute resolvers in DYNAMIXEL XL330-M288-T motors, the system recovers its orientation instantly after power cycles. No homing, no limits, and no drift—just persistent, mathematical accuracy.

The Pico 2 is programmed in MicroPython.

OMG, we’re zooming through the backlog… new protos ordered (STC31+SHT41, MT6835) and boards/libraries shipped (Terminal Block BFF, TMAG5273, VCNL4030, MAX44009, TMF8806). Still in progress: RV-8803, WF100DPZ, ADS7128, TMF882x, and VL53L5x, then we’re back to Feather designs, home sensors, and Raspi accessories.

We’ve gotten a few requests for alternatives to the popular TDK InvenSense ICS-43434, which just went into last-time-buy mode. We love this microphone ourselves because it’s an all-in-one I2S mic, so it works with a vast range of microcontrollers or microcomputers without needing a separate codec or I2C configuration.

Let’s find another I2S microphone, ideally with about the same footprint and 3V logic.

See the chosen DigiKey part.
