Building Beautiful Boards With Star Simpson

December 23, 2016 by 17 Comments

Over the last decade or so, the cost to produce a handful of custom PCBs has dropped through the floor. Now, you don’t have to use software tied to one fab house – all you have to do is drop an Eagle or KiCad file onto an order form and hit ‘submit’.

With this new found ability, hackers and PCB designers have started to build beautiful boards. A sheet of FR4 is no longer just a medium to populate parts, it’s a canvas to cover in soldermask and silkscreen.

Over the last year, Star Simpson has been working on a project to make electronic art a reality. Her Circuit Classics take the original art from Forrest Mims’ Getting Started In Electronics notebooks and turn them into functional PCBs. It’s a kit, an educational toy, and a work of art on fiberglass, all in one.

At the 2016 Hackaday Superconference, Star gave her tips and tricks for producing beautiful PCBs. There’s a lot going on here, from variable thickness soldermasks, vector art on a silkscreen, and even multicolored boards that look more at home in an art gallery than an electronics workbench.

Solving IoT Problems With Node.js For Hardware

December 22, 2016 by 10 Comments

Tod Kurt knows a thing or two about IoT devices. As the creator of blink(1), he’s shipped over 30,000 units that are now out in the wild and in use for custom signaling on everything from compile status to those emotionally important social media indicators. His talk at the 2016 Hackaday SuperConference covers the last mile that bridges your Internet of Things devices with its intended use. This is where IoT actually happens, and of course where it usually goes astray.

Alan Yates: Why Valve’s Lighthouse Can’t Work

December 21, 2016 by 51 Comments

[Alan Yates] is a hacker’s engineer. His job at Valve has been to help them figure out the hardware that makes virtual reality (VR) a real reality. And he invented a device that’s clever enough that it really should work, but difficult enough that it wasn’t straightforward how to make it work.

In his presentation at the Hackaday Supercon 2016, he walked us through all of the design and engineering challenges that were eventually conquered in getting the Lighthouse to market. We’re still a bit overwhelmed by the conceptual elegance of the device, so it’s nice to have the behind-the-scenes details as well.

Softer Side Of Robots Is Future Of Space

December 20, 2016 by 7 Comments

What will next generation space suits look like? Kari Love is making the case that new space suits will exhibit the best in soft robot technology. The problem is that most people don’t really understand much about soft robots, or about space for that matter. Her talk at the Hackaday SuperConference explores the research she has been doing into future generations of space suits. Check out the video below and then join us after the break for more on this topic.

Samy Kamkar Illustrates How To Be A Hardware Hacker

December 19, 2016 by 4 Comments

Samy Kamkar is well known for many things, but lately it has been his hardware security hacks that have been turning heads. The nice thing to know is that, despite not having a background in hardware, Samy is able to run with the best of hardware researchers. At the Hackaday SuperConference he offered words of advice for anyone trying to walk the path of discovery with an exciting new piece of electronics. One might say it’s a crash-course in how to be a hardware hacker.

Building The First Ternary Microprocessor

December 16, 2016 by 97 Comments

Your computer uses ones and zeros to represent data. There’s no real reason for the basic unit of information in a computer to be only a one or zero, though. It’s a historical choice that is common because of convention, like driving on one side of the road or having right-hand threads on bolts and screws. In fact, computers can be more efficient if they’re built using different number systems. Base 3, or ternary, computing is more efficient at computation and actually makes the design of the computer easier.

For the 2016 Hackaday Superconference, Jessie Tank gave a talk on what she’s been working on for the past few years. It’s a ternary computer, built with ones, zeros, and negative ones. This balanced ternary system is, ‘Perhaps the prettiest number system of all,’ writes Donald Knuth, and now this number system has made it into silicon as a real microprocessor.

Chris Conlon: Device Security 101

December 14, 2016 by 10 Comments

We all wring our hands over the security (or lack thereof!) of our myriad smart devices. If you haven’t had your home network hacked through your toaster, or baby cam, you’re missing out on the zeitgeist. But it doesn’t have to be this way — smart devices can be designed with security in mind, and [Chris Conlon] came to Pasadena to give us a talk on the basics.

He starts off the talk with three broad conceptual realms of data security: data in transit, data at rest on the device, and the firmware and how it’s updated. A common thread underlying all of this is cryptography, and he devotes the last section of his  talk to getting that right. So if you’d like a whirlwind tour of device security, watch on!
