A rechargeable digital altimeter (for model rockets only) that
analyzes flight altitude, acceleration, top speed, flight duration and 6
other important flight statistics.
The AltimeterTwo retains the rugged design, easily-readable LCD,
small size, and rechargeability of the AltimeterOne. With the addition
of a 3-axis accelerometer and a 4X speed increase in processing speed,
it can provide a full suite of important flight statistics that can help
you analyze and improve your rocket’s performance.
As of March 2012, the Jolly Logic AltimeterTwo has been approved by the National Association of Rocketry for use in rocketry competitions.
This is the New and Improved AltimeterTwo with the following updates:
1. More advanced
can see from the images that screens are more clearly labeled.
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
c. Battery level is now indicated
as a percentage, such as “Battery Level 75%.”
2. Stores last
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
can also choose Erase to clear all flights.
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
new battery has a connector, so it can be replaced. It’s a custom battery, so
we’ll offer replacement units.
new design has a larger, sturdier slot that’s easier to attach with a line.
Hooks and rings are no longer needed or included. If any of you want to offer
Kevlar line or loops, they would be a handy accessory.
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.
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.
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 as it nears launch.
5. USB Port
rather than a built-in plug to recharge (cable included)
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,
6. More parts
The battery and
display have connectors. Like the outside case, it’s easy to snap replacements
Specific to AltimeterTwo
data is automatically shown (no longer need to select a menu item to see
units are changed (e.g. instead of KPH, metric uses m/s)
figures are shown to two decimal places, such as Thrust Time (e.g. “1.99
4. Instead of flashing, the display
uses a “>” symbol to note acceleration overload when actual speed,
acceleration may be higher than shown (e.g. “>723 mph”)
5. Pressure is sampled 25x per
second, acceleration 250x (slight speed up)
