DESKTOP WEATHER MONITOR LEAVES NOTHING TO CHANCE

[Mirko Pavleski] has put together a little weather station for himself that combines Internet-sourced forecasts with physical sensor data to give him a complete view of his local conditions. There’s no shortage of weather applications for our smartphones and computers that will show us the current local conditions and the forecast for the next couple of days. It’s so easy to pull weather data from the vario ...

THE PIANIST OCTOPUS

MIDI has been around for nearly forty years, but what do you do if you have an old ‘toy’ keyboard without MIDI? Or really any way to make it sound good? You could turn it into a player piano, and that’s exactly what [Alessandro] did with an old toy keyboard. It’s The Pianist Octopus, and it is perhaps the coolest, neatest pianist you’ve ever seen. This build uses 24 individual 9 gram hobby servos, which of ...

Soil sensor mini kit shows if plant needs watering

Adafruit Circuit Playground Express Soil Sensor Mini Kit is designed to measure the soil moisture content. This kit, available now from Mouser, is based on the Circuit Playground Express platform and delivers the measurement utilising a nail and alligator clip. As the moisture encompassing a nail in the plant pot rises, the board detects the change and outputs the result as through the design. The platform ...

DEAD BUG ARDUINO IS LIVELY AND SHIELD-COMPATIBLE

Microcontroller demo boards such as the Arduino UNO are ubiquitous on Hackaday as the brains of many a project which inevitably does something impressive or unusual. Sometime someone builds a particularly tiny demo board, or an impressively large one. In the case of the board featured here, the Arduino is a gorgeous labor of love which can’t really be called a board since there is no PCB. Instead of the tra ...

UNCONVENTIONAL DRONE USES GAS THRUSTERS FOR CONTROL

You’ve got to hand it to [Tom Stanton] – he really thinks outside the box. And potentially outside the atmosphere, to wit: we present his reaction control gas thruster-controlled drone. Before anyone gets too excited, [Tom] isn’t building drones for use in a vacuum, although we can certainly see a use case for such devices. This is more of a hybrid affair, with counter-rotating props mounted in a centrally ...

The ‘tough road’ to Nagaland Science Centre, Dimapur

Even as the number of visitors to the Science Centre located behind Super Market here, which also houses the Innovation Hub & Space Education Centre, has steadily increased from 6,775 in 2014 to 17,866 in the past 12 months, its shabby immediate surroundings remains a perennial eyesore. Little or nothing seems to have been done to improve the condition of the road. Nagaland chief minister Neiphiu Rio ha ...

REPURPOSED PLASTIC PROTECTS PCBS

An errant wire snipping across the wrong electrical pins spells the release of your magic smoke. Even if you are lucky, stray parts are the root of boundless malfunctions from disruptive to deadly. [TheRainHarvester] shares his trick for covering an Arduino Nano with some scrap plastic most of us have sitting in the recycling bin. The video is also after the break. He calls this potting, but we would argue ...
