Today's electronics are wonderful; you can fit a lot of measurement capability into a very small package. There are a goodly number of choices available from various vendors and it is a very natural thing to compare capabilities and accuracy, especially when new products hit the market. That's one reason I built the clone of the Centuri RX-16 and the beefy Big Bertha look-a-like, Beulah. Their large payload sections and interchangeable motor mounts enable me to fly multiple instruments on the same flight, facilitating comparisons.
I was perusing the Estes website last month, and came across these teacher's bundles, which feature the large 24mm powered Green Eggs rocket and some electronics gizmo called the PocketLab. The prices were a little rich for my wallet, but I was intrigued by the PocketLab - I had not heard of it. A Google search instantly produced the manufacturer's website, where I learned that the PocketLab included in the Estes bundles was the PocketLab Voyager, a 1.5 x 1.5 x 0.6 inch mini laboratory capable of making measurements of the following:
- Angular Velocity
- Magnetic Field
- Barometric Pressure
- Infrared Rangefinder
- Internal Temperature
- Temperature Probe
- Light Intensity
