(Note - ‘Remove before Flight’ tag is not included with product. It is shown here to highlight the pyro safety shunt plug, which is included.). A Safety shunt with the “Remove Before Flight” banner can be ordered for $8.00

The G-Wiz MC Recording Altimeter is shown here.  The RS-232 connector is visible in the upper left, the new beeper in the lower left. All power is supplied via the header, shown in the lower center. There are two LEDs - a green status LED on the right of the header, and a red armed LED above the header.  Specifications below.

Below are some sample screens from the FlightView software, available free as a download, or $5 for a CD.  Continuously updated, runs on PCs, Macs, and Linux machines.  Others possible, contact us for info. Click on image for larger picture.

Specifications:

  • Pyro output 1 - Jumper select between Launch detect (for clusters) and Burnout detect (for staging)
  • Pyro output 2 - Fires at Apogee detect.  Apogee detection is always based on Accelerometer data, and is not subject to problems with Mach transition.
  • Pyro output 3 - Fires at a fixed low altitude, jumper selectable between 400’ or 800’.  Also, may be configured to fire a given number of seconds after Apogee instead.
  • Status LED / Speaker shows and beeps readiness at launch, and maximum altitude upon landing. Readiness consists of Continuity checks, and both CPU and Pyro battery voltage levels.
  • Arming jack provided on board. Not vibration sensitive, and continuity checks work even when dis-armed.
  • Analog to Digital converter reads accelerometer and barometric sensors to 12 bit precision. Equivalent to about 7 ft/count barometric, or .03 G per count acceleration.
  • Acceleration and Barometric data sampled and recorded 16 times per second along with all detected events.  Enough memory on board for up to 4 min of flight.
  • Standard serial port connector.
  • Graphing software provided works on PC/Windows, Mac
  • Software updates provided free on web.
  • High performance RISC processor uses proprietary techniques to calculate altitude properly.  It does not rely on linear simplifications, but follows atmospheric pressure to altitude models very closely.
  • High current FET driven pyro outputs are capable of delivering up to 8 amps for a full second, each.  Outputs capable of delivering up to 50 amps are available on request.
  • Can use 2 batteries to ensure that the battery driving the pyro output does not interfere with the computer.
  • Optional low current mode (jumper selected) allows use of one battery by limiting current draw.  Works with DaveyFire 28B and Pratt Hobbies WEC-1A.  May work with other low-current matches as well.
  • Reverse voltage protection on all connections.
  • Positive retention header is standard.
  • Complete with mounting standoffs and battery clips.  Mounting is compatible with G-Wiz LC.
  • MC HiG has a 100g sensor, for those extreme machines!
  • Unit dimensions: 4.9” x 0.9”
  • Prices:  MC: $194.95 SRP, MC HiG: $269.95 SRP
