The ancient art of sailing can be very intimidating for the uninitiated given the shifty nature of wind. To help understand the interaction of wind direction and board orientation, [KifS] designed a hands-on sailing demonstrator that lets students grasp the basics before setting foot on a real sailboat. The demonstrator uses a potentiometer as a tiller to […]

In this Instructable, I will walk you through the steps to build an IoT Air Quality Sensor. This is an inexpensive air quality sensor with reasonable accuracy and is accessible to internet through WiFi. This project is to integrate 3 sensors that detect different kinds of gases and particles with Nodemcu and then, send the
One of the biggest upsides of open communications standards such as CAN or SPI is that a whole world of vehicle hacking becomes available, from simple projects like adding sensors or computers to a car or even building a complete engine control unit from the ground up. The reverse is true as well; sensors and
Hello everyone, welcome back to Techatronic. Today, we’re diving into a highly practical project – the Bidirectional Counter. Our goal with this project is to tally individuals passing through the sensor. Bidirectional counters have become increasingly prevalent, especially aiding us during the pandemic. They find specific utility in seminar halls and conference rooms, accurately recording

Following on the heels of their Raspberry Pi 5 launch and some specifications for their RP1 all-in-one peripheral chip, the Raspberry Pi folks have now released an update to the HAT peripheral hardware specification reflecting the new model. Called the HAT+, it represents a major step forward with some significant changes. Most visible will be changes to
TDK-Micronas‘ HAL1880 is an entry-level Hall-effect sensor with ratiometric analog output, offering the best compromise related to sensor function vs system cost. It includes programmable clamping to extend error signaling capability and diagnostics associated with the state of various internal circuits (magnetic signal out of range). A one-pin programming interface enables the simultaneous programming of several devices
