Gliderscore is a program developed by Gerry Carter that not only scores a model plane flying competition, but provides timing for the various flying tasks One feature of Gliderscore Timer is that it outputs a Serial ASCII string that contains the countdown time, the group , the round and whether it is working time or

A Chaser Circuit consists of a clocked IC or other electronic unit like an Arduino that drives an array of LEDs in such a way that individual LEDs (or small groups of LEDs) turn on and off in a predetermined and repeating sequence, thus producing a visually attractive display in which one or more ripples

ROOAAARR!! Before you learn how to train your dragon, you need to first obtain a dragon, and there’s no better way than to make it yourself! This guide will explain the steps I took to create a scale model animatronic dragon, and in doing so I hope you might also learn how to follow similar

When making videos with a tripod fluid head, there aren’t that many movements you can do. You’ve got tilt and pan – so basically either a vertical movement or a horizontal movement. Both of these have one common characteristic: the camera stays in pretty much the same space for the whole movement, meaning you can’t

[email protected], January 2021 Here, we propose an open-source, portable, autonomous, cheap and easy-to-use device to monitor and record the concentration of CO2 in ambiant air in real-time. Using CO2 as a proxy for respiratory aerosols, the device can help define best practices regarding the ventilation of closed space (an important anti-Covid19 measure). Starting from early
CO2 Monitoring As an Anti-Covid19 Measure Continue Reading
In addition to gambling, dice (die – singular) are used in many board games, e.g., Backgammon, Monopoly, Yahtzee, Liar’s Dice, Dungeons & Dragons, Trouble, etc. Common dice are usually white with black “pips”. They are sometime known as d6 or D6. In this Instructable, the results of a simulated toss of a die (i.e., a

This fun little project will allow you the trivial joy of letting a electronic network announce that you have rain! The AI controlled, tear eliciting price’d Tesla has been rumored to have sensors that awaken the windshield wipers at the onset of rain. Being in a fully glass-enclosed cabin you would think that the obviousness

The following instructable describes a easy to build and inexpensive device to perform pressure measurements and demonstrate Boyle’s law, using the micro:bit in combination with the BMP280 pressure/temperature sensor. Whereas this syringe/pressure sensor combination has already been described in one of my previous instructables, the combination with the micro:bit is offering new opportunities, e.g. for class

Wireless power transfer systems are well on their way to replacing conventional wired charging. Ranging from tiny biomedical implants all the way to wirelessly recharging huge electric vehicles. An integral part of the research on wireless power is minimizing the magnetic field density. The International Commission on Non-Ionizing Radiation Protection (ICNIRP) provides scientific advice and
3-Axis Magnetic Field Sensor Continue Reading
Some might say that it belongs to Ron Weasley now, but to me & most of the Harry Potter fans, it’ll always be Dumbledore’s Deluminator. It was designed by Albus Dumbledore, and the first time we get to know about it is when he uses it to Put Out the lights on Privet Drive so he could
