"High Striker" with PocketLab & ScratchX

Submitted by Rich on Sat, 09/01/2018 - 19:29

Carnival Games

Most everyone enjoys a carnival!  Some like the food--from cotton candy, to funnel cakes, to ice cream.  Others enjoy rides such as the carousel, Ferris wheel, and bumper cars.  Many like to test their skills in games like "Milk Bottle", "Balloon and Dart", and "Ring Toss".  One of the most well-know skill games is "High Striker", sometimes called "Ring the Bell" or "Strongman Game".  This game is commonly played by guys trying to impress girlfriends and wives with their macho strength.  In this game, a large mallet is used to strike one end of a lever.  Th

A Tactile Sensor ON/OFF ScratchX Switch

This lesson provides an example of how to ScratchX program PocketLab Voyager's tactile sensor as an ON/OFF switch.  If you have a device such as a light bulb, motor, or robot that is under control of ScratchX, then the code in this lesson may be a starting point for you.  The ScratchX program assumes that the device can be in any one of two possible states, which we will call ON and OFF.

Theremin Synth Music with Voyager/ScratchX

Submitted by Rich on Thu, 08/23/2018 - 15:25

Introduction

theremin , named after its Russian inventor in the early 1900's, is an electronic musical instrument that is controlled without any contact by the musician.   Volume is controlled by moving one hand near one antenna, while pitch is controlled by moving the other hand near a second antenna.  The sound is generated by a pair of high-frequency oscillators.

A PocketLab Voyager Hand Dynamometer

Hand and finger strength is vital in many aspects of life--from sports such as rock climbing to jobs including airline baggage workers.  PocketLab Voyager's tactile sensor can be used to construct a very simple hand dynamometer to measure strength of a person's hands and fingers.  Figure 1 shows a simple dynamometer constructed by the author.  It consists of a 2" x 2" x 4" block of wood to which the PocketLab tactile sensor has been attached using removable double stick poster tape.

Heel Pressure: Running versus Walking

Submitted by Rich on Fri, 08/10/2018 - 18:28

Heel Pressure

Do you really know how to walk or run?  PocketLab's tactile pressure sensor provides for an opportunity for your students to investigate foot pressure during these activities.  Improper form can ultimately lead to unwanted visits to a podiatrist.  Whenever you take a step, your body places pressure on muscles, joints and tendons in your legs, knees, ankles, feet and toes.   Controlling heel pressure is a key factor to prevent injuries in this regard.

PocketLab/Ozobot LIDAR Demonstration

Submitted by Rich on Fri, 07/06/2018 - 23:05

Introduction

LIDAR—an acronym for Light Detection and Ranging—is a method for remote sensing to measure distances.  While LIDAR commonly uses reflected laser light to accomplish this, students can investigate LIDAR principles by using Voyager’s IR rangefinder in conjunction with Ozobot Evo.  Ozobot is a tiny programmable robot that can follow lines.  In this activity, PocketLab Voyager is mounted on top of Ozobot.  While Ozobot t

RC Car Fun!!!

Here is a fun summertime activity!  Race an RC car with PocketLab Voyager. Challenge your friends to see who can negotiate a series of cones in the shortest amount of time without hitting any of the cones.  Start and end times are obtained by Voyager's magnetometer as the RC car passes by magnets.  

PocketLab/Phyphox Tracer Lab

Submitted by Rich on Thu, 06/07/2018 - 18:08

Introduction to this Lab

This is a quick and fun lab for makers!  In this lab, a pair of PocketLabs and Phyphox software are used to make a tracer.  As shown in Figure 1, the pair of PocketLab Voyagers are mounted to a small movable rectangular piece of plastic, perpendicular to one another and parallel to two edges of the plastic.  A small black circle is taped to the plastic to serve as the point for following the item to be traced.  In our example, a five-pointed star is traced.  One of the Voyagers is labeled X, and it
