Product Description

A peanut-sized altimeter with super-sized features!  This tiny, easy to use altimeter audibly reports your rocket's peak altitude and maximum velocity after flight via a sequence of beeps.  A post-flight warbling siren sound makes finding small rockets in tall grass easier.

The Pnut collects flight data (altitude, temperature, and battery voltage) at a rate of 20 samples per second throughout the flight and stores them for later download to a computer.  It retains data from the most recent 31 flights (up to 9 minutes per flight) even with power removed.  The optional DT4U data transfer kit includes software for graphing and printing a wide range of characteristics including altitude, velocity, and more.

Despite its small size and low price, the Pnut is capable of recording flights of up to 100,000 foot altitude with industry-leading precision and accuracy.

A built-in Lithium Polymer rechargeable battery will run the Pnut for up to 100 hours between charges.

NOTE:  Due to changes in the USPS shipping regulations, this item cannot be shipped to Italy or Germany.

Features

  • Works to 100,000 feet MSL, audibly reports peak altitude and maximum velocity after flight.
  • Stores 31 flights of 9 minutes each (altitude, temp­erature, and battery voltage at 20 samples per second) for download to a computer with the optional DT4U USB interface.  Data are preserved with power off.
  • No mach delay necessary for mach+ flights:  Automatic MachLock assures proper operation with any flight.
  • Built-in rechargeable Lithium Polymer battery.
  • Precision sensor & 24 bit ADC yield superb 0.1% accuracy.
  • Built-in voltmeter reports battery voltage on powerup – no more guessing about battery condition.
  • Post flight locator siren aids in locating your rocket.
  • Pressure sensor is immune to false triggering from exposure to sunlight.
  • Highly resistant to false trigger from wind gusts; tested in 100+ MPH winds!
  • Low power design runs for days on a single charge.  Post-flight locator siren will run for up to two weeks, giving you multiple “second chances” to find a lost rocket.
  • Telemetry output for real-time data in flight with your RF link.
  • Rugged SMD construction, stringent QC testing, and internal self-diagnostics assure uncompromising reliability.
