Orbigator is an open-source, physical satellite tracker

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.

The Great Search – ICS-43434 I2S Microphone Replacement #TheGreatSearch #adafruit @adafruit

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.

International Women’s Day 2026 #GiveToGain #IWD2026 #WomensHistoryMonth

Today is International Women’s Day. While we celebrate Women’s History Month throughout March, today in particular we can celebrate the women in the world. Keep battling for equality.

International Women’s Day (IWD) has been around for over a hundred years, as have many of the issues still impacting women’s advancement. Since 1911, IWD belongs to all who care about gender equality. Celebrate women’s achievement. Raise awareness about discrimination. Take action to forge gender parity. All IWD activity is valid, that’s what makes IWD so inclusive.

Every year focuses on a theme and for 2026 the theme is Give to Gain:

Give To Gain emphasizes the power of reciprocity and support. When people, organizations, and communities give generously, opportunities and support for women increase. Giving is not a subtraction, it’s intentional multiplication. When women thrive, we all rise.
