Simple PWM Generator for
Testing Speed Controllers The Thrifty Throttle from AndyMark is a low cost no-frills method to test an electromechanical system before the control software is
complete. The Thrifty Throttle generates a PWM
signal that can be used to drive motor controllers.
It has a simple interface to switch between Arduino
extended range PWM generation (~540 ms to 2,300 ms)
and the standard servo range (100 ms to 2,000 ms) used in
most speed controllers.
• Input Voltage: Standard 9.0 VDC battery
• Pulse Width Endpoints: Standard servo range
or Arduino extended range.
• Size: 3. 25" x 1.25" x 0.9".
• Weight: 0.04 lbs.
• PWM generation
• Comfortable handheld
device with one hand
• 9V battery

PRIME Mix for STEM
and Robotics Pitsco Education’s latest innovation is poised to transform STEM robotics in the classroom,
as well as in national and international
TETRIX® PRIME is a revolutionary new
robotics building system designed to teach
various STEM concepts without the construction
complexities inherent in other building systems.
PRIME is engineered to be simple and intuitive,
enabling students to construct and modify
robots easily and quickly.
Making the robust PRIME Building System
unique is a patented “quick rivet” snap fastener for fast and
secure assembly. In addition, parts can be connected with a
specialized thumbscrew that provides additional strength
and durability, making robots sturdy enough for even the
most demanding competitions.
The PRIME Starter Set includes a gamepad-style four-channel wireless controller for easy operation of the motors
and servos that bring robots to life. A builder’s guide
enables students to begin construction on any of three hero
models within minutes of opening the box.
Additional part packs expand design possibilities, and
compatibility with various programming platforms (National
Instruments’ myRIO, LEGO® Education’s NXT and EV3,
Arduino, and Raspberry Pi, among others) empowers
students to engineer robots capable of performing
whatever their minds imagine.
TETRIX PRIME Building System elements are designed
to connect with existing TETRIX MAX components,
providing an ideal continuum of classroom robot integration
and learning. All TETRIX building system elements are
compatible with kits and sets used in FIRST® Tech
Challenge; SkillsUSA Robotics: Urban Search & Rescue; and
the World Robotics Olympiad Open and College categories
