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

Posted on July 9, 2018 by Roger Cheng

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

Programmable Air Makes Robotics A Breeze

Posted on May 24, 2018 by Kristina Panos

[Amitabh] was frustrated by the lack of options for controlling air pressure in soft robotics. The most promising initiative, Pneuduino, seemed to be this close to a Shenzhen production run, but the creators have gone radio silent. Faced with only expensive alternatives, he decided to take one for Team Hacker and created Programmable Air, a modular system for inflatable and vacuum-based robotics.

The idea is to build the cheapest, most hacker-friendly system he can by evaluating and experimenting with all sorts of off-the-shelf pumps, sensors, and valves. From the looks of it, he’s pretty much got it dialed in. Programmable …read more

Repair Job Fixes Compressor, Gets in Online

Posted on November 5, 2017 by Dan Maloney

We’ll never cease to be amazed at the things people try to put on the Internet of Things. Some are no-brainers, like thermostats, security cameras, and garage door openers. Others, like washing machines and refrigerators, are a little on the iffy side, but you can still make a case for them. But an IoT air compressor? What’s the justification for such a thing?

As it turns out, [Boris van Galvin] had a pretty decent reason for his compressor hacks, and it appears that the IoT aspect was one of those “why not?” things. Having suffered the second failure of his …read more

Toy Car Pumps the Wheels with Balloon Power

Posted on March 16, 2017 by Mike Szczys

We’ve had our eye on [Greg Zumwalt]. He’s been working on some very clever 3D-printed mechanisms and his latest prototype is an air engine for a toy car. You can supply the air for the single cylinder with a compressor, or by blowing into it, but attaching an inflated balloon makes the system self-contained.

Last week we saw the prototype of the engine by itself, and wondered if this had enough power to drive a little train engine. We were almost right as here it is powering the front wheels of a little car.

This isn’t [Greg’s] first rodeo. He’s …read more

Brutal Water Cannon Defeats Summer Heat; Kills it on Documentation

Posted on June 21, 2016 by Dan Maloney

There’s a war on, and while this over-the-top water blaster is certainly an escalation in the Water Wars arms race, that’s not the war we’re referring to. We’re talking about the Documentation War. Hackers, you’re on notice.

If you want to see how a project should be documented, look no further than [Tim]’s forum posts over at WaterWar.net. From the insanely detailed BOM with catalog numbers and links to supplier websites, to scads of build photos with part number callouts, to the finely detailed build instructions, [Tim] has raised the stakes for anyone that documents any kind of build.
