3D Printer Guardian Watches for Worst-case Failures

Posted on by

Some devices have one job to do, but that job can have many facets. To [jmcservv], an example of this is the job of protecting against worst-case failures in a 3D printer, and it led him to develop the 3D Printer Watchdog Guardian. When it comes to fire, secondary protection is the name of the game because it’s one thing to detect thermal runaway and turn off a heater, but what if that isn’t enough? The MOSFET controlling the heater could have failed closed and can no longer be turned off in a normal sense. In such cases, some kind …read more

Human-Computer Interface Challenge: Change How We Interact with Computers, Win Prizes

Posted on by

Pay no attention to the man behind the curtain. It’s a quote from the Wizard of Oz but also an interesting way to look at our interactions with electronics. The most natural interactions free us from thinking about the ones and zeros behind them. Your next challenge is to build an innovative interface for humans to talk to machines and machines to talk to humans. This is the Human-Computer Interface Challenge!

The Next Gen of HCI

A Human-Computer Interface (or HCI) is what we use to control computers and what they use to control us get information to us. HCIs …read more

Harvesting Power From Microwave Popcorn

Posted on by

One of the challenges in this year’s Hackaday Prize is Power Harvesting where we’re asking everybody to create something that harvests energy from something. It could be solar, it could be harvesting energy from a falling weight. If you’d like to give a TED talk, it could be harvesting energy from sound waves. It could be harvesting energy from ambient RF, and where’s the best place to harvest ambient RF? That’s right, next to a microwave.

[Jurist]’s entry for the Power Harvesting Challenge in this year’s Hackaday Prize is a simple device that mounts to the front door of a …read more

Charging USB-C Devices Off Of LiPo Battery Packs

Posted on by

When it was introduced in the late 90s, USB was the greatest achievement in all of computing. Gone were the PS/2 connectors for keyboards and mice, ADB ports, parallel ports, game ports, and serial ports. This was a Tower of Babel that would unite all ports under one standard universal bus.

Then more ports were introduced; micro, mini, that weird one that was a mini USB with more connectors off to the side. Then we started using phone chargers as power supplies. The Tower of Babel had crumbled. Now, though, there is a future. USB-C is everything stuffed into one …read more

This Is Your Last Chance To Design The Greatest In Power Harvesting

Posted on by

This is your last weekend to get your project together for the Power Harvesting Challenge in this year’s Hackaday Prize. We’re looking for projects that harvest energy from the ether, and power electronics from solar, thermal, wind, light, or random electromagnetic fluctuations. Is it going to save the world? Maybe, but it’s a great excuse to build some really cool electronics. If you have an idea in mind, this is your last weekend to enter it in the Power Harvesting Challenge.

The Hackaday community has thrown itself full-force into the Hackaday Prize, and there are hundreds of projects entered in …read more

Air Quality Readings at a Glance

Posted on by

Since the industrial age, air pollution has increasingly become a problem on society’s radar. Outside of concerns about global warming and greenhouse gases, particulate emissions can be highly hazardous to human health. Over time, various organizations have set up measuring systems to check and report the particulate pollution level in cities around the world – but what if you could get an immediate idea on the pollution in your immediate vicinity? Enter less-smog.org.

In an integration sense, it’s a straightforward project. An ESP-12F is used as the brains behind the operation. This then talks to a combination of sensors to …read more

Robotic Muscles from Fishing Line and Nichrome

Posted on by

Did you know that under the right conditions, nylon can be used as a type of artificial muscle? We certainly didn’t until we came across [Brandon T. Wood]’s Material Linear-Actuator for Robotics entry for the 2018 Hackaday Prize.

When [Brandon] first learned about Nylon Linear Material Actuators (NLMAs), he became determined to find a repeatable and practical method of making and experimenting with them. This is how it works: hyper-wound coils of nylon, when heated, will contract along their length while expanding in width. Upon cooling, they return to their original shape.

[Brandon] has been busy mainly with the kind …read more

Open Hardware Takes Charge in Papua New Guinea

Posted on by

You probably don’t think much about charging your phone. Just find an outlet, plug it in, and wait a while. Can’t find a cable or wall wart? A rainbow of cheap, candy-colored options awaits you down at the brightly-lit corner drugstore.

This scenario couldn’t be further from reality in third world countries like Papua New Guinea, where people living in remote jungles have cell phone coverage, but have to charge their phones by hooking them up directly to cheap solar panels and old car batteries.

[Marius Taciuc] wants to change all of that. At the suggestion of his friend [Brian], …read more

Putting More Tech Into More Hands: The Robin Hoods of Hackaday Prize

Posted on by

Many different projects started with the same thought: “That’s really expensive… I wonder if I could build my own for less.” Success is rewarded with satisfaction on top of the money saved, but true hacker heroes share their work so that others can build their own as well. We are happy to recognize such generosity with the Hackaday Prize [Robinhood] achievement.

Achievements are a new addition to our Hackaday Prize, running in parallel with our existing judging and rewards process. Achievements are a way for us to shower recognition and fame upon creators who demonstrate what we appreciate from our …read more
