The Leap Motion Makes Robots Bend To Your Will

Posted on by

We just wrapped up the Human Computer Interface challenge in this year’s Hackaday Prize, and this project is pushing boundaries we’ve hardly seen before. [Giovanni Leal] is using a Leap Motion controller to move a robotic arm around in space.

The robot arm in question comes from Owi, and it is by every measure not a good robot arm. It is, however, an excellent toy filled with motors and plastic linkages that serves as a good stand-in for a proper robotic arm.

Control of this toy robot arm is done through a Leap Motion controller. While the Leap Motion is …read more

Hackaday Links: September 30, 2018

Posted on by

If you’re looking for an Open Source computer, good luck. The RISC-V stuff isn’t there yet, and with anything else you’re going to be dealing with NDA’d Intel, AMD, or some other proprietary cruft. System76, however, makes the most big-O Open computer, and they will be announcing a new Open computer called the Thelio next month. It was on display at the Open Hardware Summit, although smartly there were no pictures taken of this box. Liliputing has reported on it, but there are a few things wrong with that speculation. No, it’s not RISC-V. We’re looking at x86 here. …read more

Give Yourself A Sixth Sense With An Arduino

Posted on by

If you carry a smartphone around in your pocket, you have a GPS navigation system, a compass, an altimeter, and a very powerful computer at your fingertips. It’s the greatest navigational device ever created. To use this sextant of the modern era you’ve got to look down at a screen. You need to carry a phone around with you. It’s just not natural.

For this entry into the Hackaday Prize, [Vojtech Pavlovsky] has an innovative solution to direction finding that will give you a sixth sense. It’s a headband that turns your temples into the input for a clever way …read more

FPGA Jacked Into Pinball Machine Masters High Scores

Posted on by

How do you preserve high scores in an old arcade cabinet when disconnecting the power? Is it possible to inject new high scores into a pinball machine? It was the b-plot of an episode of Seinfield, so it has to be worth doing, leading [matthew venn] down the rabbit hole of FPGAs and memory maps to create new high scores in a pinball machine.

The machine in question for this experiment is Doctor Who from Williams, which, despite being a Doctor Who pinball machine isn’t that great of a machine. Still, daleks. This machine is powered by a Motorola …read more

The New, Improved Open Hardware Certification Program

Posted on by

Today at the Open Hardware Summit at MIT, OSHWA, the Open Source Hardware Association has announced a huge revision to the Open Hardware certification process. The goal here is to design a better platform for creating Open Hardware.

While all hardware already certified as Open Hardware will remain Open Hardware, this revamp of the ‘hub’ of the certification process is greatly improved. There’s a new website. There are learning modules telling everyone what it means to be Open Source hardware. There are community examples — real-life walk-throughs of projects that have already been created. There’s a streamlined certification process, and …read more

The Exquisite Badges Of Open Hardware Summit

Posted on by

The past few years have been all about electronic conference badges and this year is no different. Right now, we’re setting up at the Open Hardware Summit at MIT, and this year’s badge is nothing short of extraordinary. It’s a WiFi and Bluetooth-enabled e-paper badge, individually programmed for every attendee. The 2018 Open Hardware Summit badge is a work of art, and it was all created over on hackaday.io.

This board is based on the ESP trINKet designed by [Mike Rankin] with additional hardware design from [Alex Camilo]. The badge is based around the ESP32-wroom-32 module with a 2.13 inch …read more

Maker Faire NY: Infinite Autonomous 3D Printing

Posted on by

Although it’s not an idea that has yet trickled down to $200 printers drop-shipped from China, one of the most innovative ideas in the 3D printing world in the last few years is putting plastic down on a conveyor belt. Yes, MakerBot was doing it back in 2010, but we’re not going to talk about that. Printing on a conveyor belt instead of a static bed allows you to easily print multiples of an object autonomously, without any human interaction. If you’re really clever, you could rotate the hot end 45° and build a piece of plastic that is infinitely …read more

Apple’s Best Computer Gets WiFi

Posted on by

The greatest computer Apple will ever make isn’t the Apple II, it isn’t the Bondi Blue iMac, it isn’t the trash can, and it certainly isn’t whatever overheating mess they’re pushing out now. The best computer Apple will ever make is the SE/30, at its time a server in a tiny portable shell, and capable of supporting 128 Megabytes of RAM thirty years ago.

Over the years, people have extended and expanded the SE/30 to absolutely ludicrous degrees, but now we have a simple way of adding WiFi to this classic computer. Over on the 68kmla forums, [ants] discovered a …read more

Adding Analog Touch To (Nearly) Any Mechanical Keyboard

Posted on by

The new hotness for DIY electronics is mechanical keyboards, and over the past few years we’ve seen some amazing innovations. This one is something different. It adds an analog sensor to nearly any mechanical key switch, does it with a minimal number of parts, and doesn’t require any modification of the switch itself. It’s a reddit thread and imgur post, but the idea is just so good we can overlook the documentation on this one.

The key development behind this type of sensor is realizing that nearly every mechanical keyswitch (Cherry MX, Kalth, Gateron) has a spring in the bottom. …read more
