After several y ears of development and testing with schools, homeschoolers, and parents we are proud to announce that the JackBord Pro, JackBord Basic, the Virtual JackBord and a range of sensors on our very own Universal Sensor Interface using our Octagon programming platform are now available. JackBord is the perfect partner to unleash the curiosity and inspire creativity in students of all ages and all abilities through authentic learning. These robust, long life multifunctional electronic devices and educational system helps students and educators with electronics, robotics, programming, science, data logging and analytics, construction, art, games, communication, teamwork. JackBord is the so lution to educators and industry needs for STEM tools that provide kinaesthetic, real world learning experiences to help equip our young learners of all abilities for the future. JackBord, your partner in STEM, opening a world of opportunity Engaging our neurodiverse rangatahi in STEM education STEM Alliance Aotearoa "The JackBord provides an excellent opportunity to engage akōnga in STEM, removing the silo-ed learning of “maths” and “science” lessons through a transdisciplinary project."

CRIsIsLab Challenge - Massey University, August 2021 The Crisis Response and Integrated Simulation Science Laboratory (CRISiSLab) is a research and learning laboratory based in the Joint Centre for Disaster Research (JCDR), Massey University, Wellington. In an effort to encourage more students into the field of Technology and Crisis Management, they ran a competition, in which students were required to design and build an earthquake alerting device or system. The purpose of the students’ device was to monitor live data from a Raspberry Shake seismometer, one of which was given to each school, and when it reached a given threshold create an alert that would warn people nearby of the impending earthquake risk. The teams from Paraparaumu College and Te Kura Māori o Porirua used JackBords extensively in their alert devices, in conjunction with JackBord’s programming language Octagon, for data processing and creating their alerting program. The results of the competition saw "Earthquack" from Paraparaumu College win the joint award for the best dashboard , and Te Kura Māori o Porirua win the award for the best alerting device. The Te Kura Maori o Porirua alerting device was based upon Rūaumoko, the god of earthquakes in Māori Mythology, holding a Waka with three warriors in it high above his head. When an alert was triggered the four JackBords used in the alerting device came into action with each one being the responsibility of one or more students. The first JackBord monitored the data coming from the Raspberry Pi Shake and sent an alert to the other 3 JackBords when an earthquake occurred. The second JackBord controlled the three Māori warriors in the waka with the number popping up depending on the severity of the quake. It was also responsible for the LEDs below Rūaumoko which represented the sea. The warriors were controlled using RC servos mounted on JacKano metal parts. The third JackBord controlled the lights on the side of the waka and the fourth was responsible for the alert sound played based upon the strength of the quake.

This is the basic program for a car with an infrared obsticle detection sensor mounted at the front. The sensor is the Infrared Proximity Obstacle Avoidance Sensor 2cm to 30cm which sends an infrared beam out the front and if this hits something it reflects back and is detected.

When it detects an obsticle at the front it will stop, go back a little, turn and then move forwards again.
