Basic skills all in one set.

Compact function generator

Sensor for triggering the digital counter in time measurements on moving objects. Suitable for opto electronic scanning of light and dark markings on moving objects or in conjunction with a reflecting foil to form a wide spaced obstruction sensor. The intensity of the laser beam is adjusted automatically according to the distance of the object. Includes reflecting foil, stand rod with screw thread, and connector lead with 8 pin miniDIN plugs.

Vibration generator for exciting oscillating and waves mechanically, such as in coil springs, a rubber cord, a wire ring or a Chladni plate. In robust plastic housing including mounting pin with 4mm socket for attaching accessories (Chladni plates, resonance wire, rubber band, etc.). Including holder for stand rod (up to 8mm dia.) on the rear side of the apparatus for the demonstration of standing waves in a coil spring. The generator is equipped with overload protection and is driven by a loudspeaker for smooth oscillations and fine travel stepping.

Digital counter/timer for measuring duration of motion, transition times, periods, pendulum periods, frequencies, as well as for counting events or Geiger tube pulses. Includes a speaker that can be turned on and off, and power supplies for direct connection to light barriers. For event counting, a fixed counting period can be programmed in a range from 0.1ms to 99999s. Counter events (e.g. start or stop) can either be triggered by a signal to the input sockets or manually via switches. The unit includes a plug-in power supply.

You can use these multi-colored dice for games, exercises in probability, basic operations, fractions, statistics, practicing and strengthening mental calculations, and more.

A colorful set of 51 plastic stacking pieces representing one whole, halves, thirds, fourths, fifths, sixths, eighths, tenths, and twelfths.
