Altimeter One Generation Two

The second-generation AltimeterOne is a rechargeable digital altimeter that reports the peak altitude of your rocket flight on a new advanced bitmapped LCD display. Its tiny size and rugged construction have helped to propel its use beyond model rockets and planes to kites, balloons, falconry, and other sports and activities. Measures Altitude up to 29500 feet above sea level!

Here are some of the more interesting ways in which the AltimeterOne has been used:

• Tethered to the leg of a hunting falcon
• On board high-altitude balloon flights
• As an on-screen altitude display in RC planes
• In science projects
• In world-record attempts for high altitude kite-flying

The Jolly Logic AltimeterOne has been approved by the National Association of Rocketry for use in rocketry competitions.

Features:

• Highly accurate 19-bit barometric pressure sensor can detect altitude changes of less than one foot
• Sunlight-readable advanced bitmapped LCD display displays maximum flight altitude
• Advanced rechargeable Lithium Polymer (increased in size and capacity from the original version) battery lasts for hundreds of launches and has a connector so it can be replaced.
• Recharges from any standard USB port with included USB cable, no batteries to replace!
• Highly accurate pressure sampling over 25 times/second (slight speed up from the 20x sec. on old version)
• Power button turns device ON/OFF and RESETs the display between flights
• Automatically powers down to conserve power
• Larger, sturdier tether point allows secure attachment, or independent streamer recovery
• Rugged fiberglass and ABS construction to survive crashes
• “Current Altitude Mode” displays current altitude in real-time

Altimeter One Generation Two User Guide

Specific changes to the new Generation Two Altimeter One

1. More advanced display
   1. You can see from the images that screens are more clearly labeled.
   2. When you hold down the button a menu appears which now smoothly scrolls. When you select a menu item, it flashes to confirm your selection. For instance, you select “Launch” instead of the cryptic “0000” to prepare for launch.
   3. Battery level is now indicated as a percentage, such as “Battery Level 75%.”
2. Stores last 100 flights
   1. If you choose History from the menu, the last 100 flights (from most recent to oldest) are shown one after another.
   2. Flights are sequentially numbered.
   3. You can also choose Erase to clear all flights.
3. New battery
   1. In the new design, the battery is much larger and will retain charge for months. When you pull this generation out of your range box, you can be more sure that it will still have power. The old design did not have great shelf life.
   2. The new battery has a connector, so it can be replaced. It’s a custom battery, so we’ll offer replacement units.
4. Slightly larger
   1. The new design has a larger, sturdier slot that’s easier to attach with a line. Hooks and rings are no longer needed or included.
   2. The slight size increase may mean it may not fit in some very small spaces that the old generation could. You should plan to check this out.
   3. There is a new accessory, the Snap Mount. If there’s a place to mount the Snap Mount, it securely holds the altimeter so you can quickly snap it in and out.
       
5. USB Port rather than a built-in plug to recharge (cable included)

The more universal USB Micro-B port is compatible with lots of chargers already out there (it’s the most common on small devices). The included cable will fit in EVERY (not just most) normal USB ports on laptops, etc. Also, it only fits one way, eliminating confusion.

1. More parts are replaceable

The battery and display have connectors. Like the outside case, it’s easy to snap replacements in.

Changes Specific to AltimeterOne

1. Current Mode is now called Realtime Mode.
2. Pressure is sampled 25x per second (slight speed up)
