It Happened At Supercon: Six Days Of Fun In A Three Day Con

November 8, 2018 by 7 Comments

A weekend for people who love hardware, by people who love hardware. It’s a simple recipe and it makes a delicious event that we call the Hackaday Superconference. If you made it to Pasadena last weekend, I’m sure going back to work on Monday was difficult after three days of far too little sleep and way too much fun. (It was for me.) If you didn’t make it to the con, set a reminder for July 1st to start watching for next year’s early bird tickets. Don’t believe me? Okay, let’s step through the hype of a weekend we’ll all remember.

Check out the recap video above and then join me after the break for a photo-heavy expose of the weekend’s highlights.

The Dual In-Line Package And How It Got That Way

November 8, 2018 by 68 Comments

For most of human history, our inventions and innovations have been at a scale that’s literally easy to grasp. From the largest cathedral to the finest pocket watch, everything that went into our constructions has been something we could see with our own eyes and manipulate with our hands. But in the middle of the 20th century, we started making really, really small stuff: semiconductors. For the first time, we were able to create mechanisms too small to be seen with the naked eye, and too fine to handle with our comparatively huge hands. We needed a way to scale these devices up somewhat to make them useful parts. In short, they needed to be packaged.

We know that the first commercially important integrated circuits were packaged in the now-familiar dual in-line package (DIP), the little black plastic millipedes that would crawl across circuit boards for the next 50 years. As useful and versatile as the DIP was, and for as successful as the package became, its design was anything but obvious. Let’s take a look at the dual in-line package and how it got that way.

Inventor Services – Maybe Right For You – Maybe

November 7, 2018 by 20 Comments

You’ve no doubt been exposed to the ads for various inventor services; you have an idea, and they want to help you commercialize it and get the money you deserve. Whether it’s helping you file legal paperwork, defending your idea, developing it into a product, or selling it, there’s a company out there that wants to help. So which ones are legit, which ones are scams, and what do you really need to make your millions?

Warnings Are Your Friend – A Code Quality Primer

November 6, 2018 by 63 Comments

If there’s one thing C is known and (in)famous for, it’s the ease of shooting yourself in the foot with it. And there’s indeed no denying that the freedom C offers comes with the price of making it our own responsibility to tame and keep the language under control. On the bright side, since the language’s flaws are so well known, we have a wide selection of tools available that help us to eliminate the most common problems and blunders that could come back to bite us further down the road. The catch is, we have to really want it ourselves, and actively listen to what the tools have to say.

We often look at this from a security point of view and focus on exploitable vulnerabilities, which you may not see as valid threat or something you need to worry about in your project. And you are probably right with that, not every flaw in your code will lead to attackers taking over your network or burning down your house, the far more likely consequences are a lot more mundane and boring. But that doesn’t mean you shouldn’t care about them.

Buggy, unreliable software is the number one cause for violence against computers, and whether you like it or not, people will judge you by your code quality. Just because Linus Torvalds wants to get off Santa’s naughty list, doesn’t mean the technical field will suddenly become less critical or loses its hostility, and in a time where it’s never been easier to share your work with the world, reliable, high quality code will prevail and make you stand out from the masses.

How The Sony PlayStation Was Hacked

November 5, 2018 by 34 Comments

Playgrounds were the comment sections of their day. Every weekday from exactly 1:17 PM until 1:43 PM there were swings to be swung, rumors to be spread, and debates to be settled by whomever was the loudest (some things never change). Allegiances were formed and battle lines were drawn based solely on what video game console you supported. It was this playground system that perpetuated the urban myths of the time.

For PlayStation fans there was the myth that you could save Aerith from her fate in Final Fantasy VII if you just cast the right spell, or the secret code in Tomb Raider that would let you see all of Lara Croft. There was the myth that no one could possibly copy a PlayStation game because all the bottoms of the discs were black. Even the very existence of the first PlayStation, the Super Nintendo PlayStation prototype, was an urban legend. The difference was that last one turned out to be true.

Let’s jump in and take a look at the cat and mouse game between modchip makers looking to defeat the original PlayStation’s copy protection, and Sony’s efforts to protect their castle.

The Linux Throwie: Powering A Linux Server With A 0.3W Solar Panel

November 2, 2018 by 63 Comments

Have you ever had one of those moments, when you’re rummaging through your spare parts heap, and have a rather bizarre project idea that you can’t quite get out of your head? You know, the ones that have no clear use, but simply demand to be born, of glass and steel and silicon?

This time, the stubborn idea in question was sort of like a solar-rechargeable LED throwie, but instead of a blinking light, it has a fully cloud-accessible embedded Linux server in the form of a Raspberry Pi 3 Model B+. Your choice of embedded Linux board should work — I just happen to have a lot of these due to a shipping error.

There were two main challenges here: First, it would have to combine the smallest practical combination of solar panel, power supply, and Li-ion cell that could run the Raspberry Pi. Second, we’ll need to remotely activate and access the Pi regardless of where it is, as well as be able to connect it to WiFi without direct physical access. In this article we’ll be dealing with the first set of problems — stay tuned for the rest.

Hands On With The Arduino FPGA

November 1, 2018 by 31 Comments

All of the tools you need to work with the FPGA Arduino — the Vidor — are now in the wild!

We reported earlier that a series of French blog posts finally showed how all the pieces fit together to program the FPGA on the Arduino MKR4000 Vidor board. Of course, I wasn’t content to just read the Google translation, I had to break out the board and try myself.

I created a very simple starter template, a tool in C to do the bitstream conversion, required, and bundled it all together in one place. Here’s how you can use my starter kit to do your own FPGA designs using the Vidor. I’m going to assume you know about FPGA basics and Verilog. If you don’t, why not check out the FPGA boot camps first?

The first thing you’ll want to do is grab my GitHub repo. You’ll also need the Arduino IDE (a recent copy) and Intel’s Quartus software. Inside, you’ll find three directories, two of which contain slightly modified copies of original Arduino files. But before you start digging in, let’s get the high-level overview of the process.
