Radiant Tech Note: One Node, Three Masters – Sharing a Gyro Line with an Altimeter and an MCU How we taught one humble analog node to be a gyro output, an MSP430 ADC input, and an I²C clock line… all at once. 1. Background: When a “Simple” Turn Coordinator Grows Up Radiant’s SafeTurn  started life as a portable digital turn coordinator with an inclinometer (“the ball”). Simple idea: Solid-state yaw gyro Nice LCD Battery power No vacuum, no spinning iron, no drama. Then reali

Radiant Tech Note – November 25, 2025 When a “Drifting” Inclinometer Wasn’t the Problem Editor’s Note At Radiant Instruments, we’re using AI as a genuine engineering partner to speed product development. The story below is a good example. James Wiebe drives the concepts, experiments, and decisions. An AI assistant helps track subtle interactions in a 4,500-line embedded program, suggests hypotheses, and occasionally guesses wrong. James challenges it, corrects it, and togethe

Last week I had the pleasure of speaking at  Tabor College  for the Nachtigall Lecture Series, and I was also invited to lecture in a couple of Computer Science classes.  I walked away from the whole experience — and from conversations with Dr.  David Janzen  and the students — with a real burst of energy. What Tabor is doing in Computer Science is genuinely cool. David also showed me the plans for the new entrepreneurship center… very nice! I’m hoping that center becomes a p

Radiant Technical Note 11.6.2025 Using Radiant Turn Coordinators on 28 V Aircraft Electrical Systems (Not applicable to SafeTurn portable units) Applies to: Radiant Turn Coordinator products, when operated from 24–28 V class aircraft electrical systems (“28 V” systems). Does not apply to: Radiant SafeTurn portable units (self-powered; do not add this resistor). 1. Background Radiant Turn Coordinators use a robust linear power chain: External Bus → 9.5 V Pre-Regulator → 5.0
