Jolly Logic Altimeter One

The AltimeterOne is a rechargeable digital altimeter that reports the peak altitude of flight on an LCD display. Its tiny size and rugged construction have helped to propel its use in rocketry and other activities. The Jolly Logic AltimeterOne has been approved by the National Association of Rocketry for use in rocketry competitions.

Next Generation advances:

1. More advanced display

a. You can see from the images that screens are more clearly labeled.

b. 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.

c. Battery level is now indicated as a percentage, such as “Battery Level 75%.”

2. Stores last 100 flights

a. If you choose History from the menu, the last 100 flights (from most recent to oldest) are shown one after another.

b. Flights are sequentially numbered.

c. You can also choose Erase to clear all flights.

3. New battery

a. 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.

b. The new battery has a connector, so it can be replaced. It’s a custom battery, we offer replacement units.

4. Slightly larger

a. 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.

b. 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.

c. 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. Happy to send you samples on request.

d. The size increase was driven by the upcoming AltimeterThree, which shares the same case and which includes a flash drive and Bluetooth wireless. More info on AltimeterThree soon.

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.

6. 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 Real Time Mode.

2. Pressure is sampled 25x per second (faster that the previous version)
