The AnaSonde Blink-ETM and
Buzz-ETM are variants of the basic
AnaSonde-ETM, Anasphere's original low-cost radiosonde
for making meteorological measurements in the lower atmosphere.
The Blink-E and Buzz-E are very low-cost measurement devices optimized
for use in the classroom and student laboratory. They also provide an
excellent introduction to the fundamental features and capabilities of the
AnaSonde radiosondes, without requiring the user to have any special skill
or additional materials - the kit and a 9-volt battery are all you need to
start making measurements and enter the world of AnaSondes!
The Blink-E and Buzz-E are both based on a standard AnaSonde-E radiosonde
circuit board. Each type measures temperature using an on-board temperature
sensor. An on-board microcontroller takes the raw measurement from the
sensor and converts it to a temperature in degrees Celsius. This number is
then presented to the user via an on-board LED (Blink-E and Buzz-E) and can
also be presented via an on-board speaker (Buzz-E only).
The number is presented either in Morse Code or as a countable number of blinks or buzzes.
This method of data presentation is useful in several ways. First, for
those intending to move on to more advanced versions of AnaSondes, this
technique provides an introduction to how the AnaSondes can transmit data
over radios. It also provides an introduction to how numbers are presented
by audio methods, and it is an easy step to go from listening to the data
from a Buzz-E to listening to the Morse code transmissions from the more
The data presentation methods are also of use in special-needs classrooms
for blind or deaf students. Yes, even blind students have built AnaSondes
from specially modified kits!
The AnaSonde Blink-E and Buzz-E are based on the AnaSonde-E radiosonde.
While the Blink-E and Buzz-E inherently have the full capability of the
AnaSonde-E, at the present time we only offer the temperature measurement
as a standard option, as the goal for these sensors is to provide the
simplest possible introduction to the world of AnaSondes. Inclusion of
other sensors (see optional configurations on the AnaSonde-E page) is
possible upon request. The temperature measurement has a 1 degree
Celsius resolution. The circuit board is 0.85 x 2.5 inches.
The data is presented to the user via an on-board LED (see the Buzz-E for
an audio output option). The number is presented as a series of blinks
of the LED. The number is presented either in Morse Code or as a countable number of blinks or buzzes. In the latter case, the numbers 1-9 are simply presented as the corresponding
number of blinks; a special blink pattern indicates the digit zero, and
another special pattern indicates a negative sign for temperatures below zero.
There is no need for any associated software or other devices to receive
data from the AnaSonde Blink-E.
Items Supplied With Each AnaSonde Blink-E.
The AnaSonde Blink-E is only offered in kit form; it consists of 10 parts
plus a circuit board. All you need to add is a 9-volt battery.
- The temperature sensor should always be installed in Channel 1.
- NO AMATEUR RADIO CALL SIGN REQUIRED for the AnaSonde Blink-E and Buzz-E!
