I wanted to create an Altimeter / VSI instrument which would work great and be inexpensive. What could I do to make it stand out? Here's a list of seven features:
Altimeter with classic needle representation, (like a steam gauge)
VSI with classic needle representation, (also like a steam gauge)
Digital values for both, in addition to the steam gauge look-a-likes
Settable Kollsman window, just like any altimeter
Adjustable calibration, as the sensor ages
Feet or Metric selection by user setup
Available for either 2 1/4 or 3 1/8 panels!
This was all achieved, with a price point of $129.95 (or less).
One behind-the-scenes test I had done on my nifty product was a trip in a calibrated altitude chamber. From 500 to 16,000 feet, the maximum error was 70 feet. Through recalibration (which was not done) the max error could have been +/- 35 feet across 16,000 feet. That's accurate (in fact, if I'm not mistaken, would meet the TSO for altimeters!
I cleaned up the numeric font representations (compared to prior Radiant Instrument products) and also came up with a nifty adapter ring for 3 1/8 panel cutouts.
This product is in stock at Aircraft Spruce, as of this writing.
Here's the purchase link:
We also have it for sale on our own website:
I appreciate your comments!

I'm interested to know the depth and power requirements. Hoping to use your multi function in a legal eagle xl. Also, what kind of sensors or tubing is required if any?
Thanks
Are you also working on ardinio two way radio? Any future plans. Maybe bofang like software controlled airbands.
