LongHive - Beehive Monitoring Using IOT via Hackster IO



Bees are critical to the livelihood of our ecosystem, but unfortunately in the past decade, bee populations have decreased by 30% [1]. In addition to the ecological impact, this instability poses an economic threat to the commercial honey bee pollination industry, which is valued at over $10 billion annually in the U.S. alone [2]. Much of the decline is attributed to a complicated phenomenon known as Colony Collapse Disorder (CCD), which results in the hive’s rapid abandonment of their queen, but the causes of CCD are not well understood. Whether you are an individual hobbyist or a commercial farmer who relies on large-scale pollination, monitoring your hive with simple sensory data can help beekeepers detect problematic trends in colony health. Our project, known as “LongHive”, is a full-service infrastructure for beehive maintenance, enabled by the Helium Network and Deep Learning (DL). Data-driven beekeepers can install our LongHive system, which fits underneath standard beehives and includes a suite of relevant sensors, a pre-trained convolutional neural network (CNN) for classifying the hive’s acoustic signatures, and a web-based dashboard for easy visualization of the transient signals.

LED Heart Beats With The Beholder via Hackaday


Many a maker likes to use their craft to create gifts for loved ones. [Jiří Praus] was celebrating having been married for 5 years, and crafted this beautiful LED heart sculpture to commemorate the occasion.

The outer shell was created by first starting with a 3D printed heart shape. This was used as a form upon which the brass wire could be soldered together to form an attractive heart-shaped cage. Inside, an Arduino Nano is hooked up to a series of WS2812b LEDs. The LEDs are flashed in time with the heartbeat of the person holding the heart, thanks to a MAX30102 heartbeat sensor. There’s also a TP4056 charge module and a small lithium battery to provide power for the device. 

Adding the heartbeat sensor really makes this project shine, forming a connection between the holder and the device itself. The tasteful craftsmanship of the brass design makes this an excellent gift, one we’re sure anyone would like to receive. We’ve seen [Jiří Praus] make the most of this artform before too, with projects like this stunning tulip or dead-bug Arduino.

When Piracy Literally Saves Lives via Techdirt


Early on in the pandemic we wrote about how some makers of medical equipment, such as ventilators, were making it difficult to impossible to let hospitals fix their own ventilators. Many have used software locks -- DRM -- and refuse to give the information necessary to keep those machines online.

And thus, it was only inevitable that piracy would step in to fill the void. Vice has the incredible story of a rapidly growing grey market for both hacked hardware and software to keep ventilators running:

In the case of the PB840, a ventilator popularized about 20 years ago and in use ever since, a functional monitor swapped from a machine with a broken breathing unit to one with a broken monitor but a functioning breathing unit won’t work if the software isn’t synced. And so William uses the homemade dongle and Medtronic software shared with him by the Polish hacker to sync everything and repair the ventilator. Medtronic makes a similar dongle, but doesn’t sell it to the general public or independent repair professionals. It’s only available to people authorized by the company to do repairs.

Tiny Duck Hunt Looks Like Big Fun via Hackaday

Unless you’ve held on to an old tube TV, did the hack that lets you use a light gun with an LCD via Wiimote receiver and a couple of microcontrollers, or live close to one of those adult arcades, you might be really jonesing to play Duck Hunt by now. It’s time to renew that hunting license, because [Danko] has recreated the game for NodeMCU boards, and it’s open season.

Instead of ducks, you get to shoot cute little Twitter-esque birds of varying sizes and point values, and a tiny cab-over truck if you wish. There’s a 60-second free-for-all, and then time is up and your score is displayed. As a special bonus, there’s no smug dog to laugh at you if don’t hit anything. Be sure to check out the demo and build video after the break.

Do Drones Help Democratize Surveillance? via Slashdot


A University of San Diego (USD) professor has just published The Good Drone: How Social Movements Democratize Surveillance. He tells a local newspaper that drones (as well as other aerial technologies like balloons, satellites, and even kites) actually help effect social change."That was my litmus test," Choi-Fitzpatrick continues. "Can I, or other people like me, use this technology for good? The thing that ties them all together is that they're all affordable and deployable by the public without regulatory oversight."

In order to prove this point, Choi-Fitzpatrick points to how the vast majority of the public uses drones for altruistic causes such as documenting human rights abuses, anti-poaching advocacy, and researching climate change research. With help from his students at USD, he meticulously scraped the internet, logging incident reports and media stories on negative drone usage. He says the data proved that, more often than not, that "the smallest categories were for spying and crime...."

It's his hope that "The Good Drone" will help the public understand the benefit of the technology before rushing to have them banned for public use... "The government already has surveillance drones monitoring protests and I think it's important that news agencies, the public and social movements also have drones to tell their side of the story as well. It's only imagery and video that will tell the full story."

The article points out that while the book will be published Tuesday, it will also be available as a free, downloadable, open access PDF. And the author's original manuscript, uploaded to PubPub's Open Peer Review platform, is already available online.

Raspberry Pi Weasley Family Clock from Harry Potter Runs Like Magic via Tom's Hardware



Sometimes fiction inspires reality—such is the case here with Bryn Dole's Weasley Family clock replica. It uses a Raspberry Pi to replicate the general functionality, going as far as to update in real-time based on your family's actual location data.

If you aren't familiar with the Harry Potter franchise, the clock is found in the home of the Weasley family. Each section of the clock represents a location rather than a point in time. There is a hand for each member of the family which moves magically into position based on where they are at a given moment. If you aren't sure where they are, you can find out in a glance using the clock.

In this project, the location information is gathered and processed using an application called Life 360. This data determines where each individual hand should dial in on the clock. Dole decided to use a grandfather clock found in a thrift store, fitted with a poster of the original clock artwork from the movie.

A beginner’s guide to robot programming with Python via The Next Web

Let’s face it, robots are cool. They’re also going to run the world some day, and hopefully, at that time they will take pity on their poor soft fleshy creators (a.k.a. robotics developers) and help us build a space utopia filled with plenty. I’m joking of course, but only sort of.

In my ambition to have some small influence over the matter, I took a course in autonomous robot control theory last year, which culminated in my building a Python-based robotic simulator that allowed me to practice control theory on a simple, mobile, programmable robot.
