2017: As The Hardware World Turns

Posted on by

The year is almost over, and now it’s time to look back on the last fifty-odd weeks. What happened in this year in hacking? 2017 will go down as the beginning of another AI renaissance, although we’re not going to call it that; this year was all about neural nets and machine learning and advancements resulting from the development of self-driving cars and very beefy GPUs. Not since the 80s have we seen more work in ‘AI’ fields. What will it amount to this time around the hype cycle? Find out in a few years.

Biohacking was big this year, …read more

Hackaday Links: Not A Creature Was Stirring, Except For A Trackball

Posted on by

Hey, did you know Hackaday is starting an Open Access, peer-reviewed journal? The Hackaday Journal of What You Don’t Know (HJWYDK) is looking for submissions detailing the tools, techniques, and skills that we don’t know, but should. Want to teach everyone how to make sand think? Write a paper and tell us about it! Send in your submissions here.

Have you noticed OSH Park updated their website?

The MSP430 line of microcontrollers are super cool, low power, and cheap. Occasionally, TI pumps out a few MSP430 dev boards and sells them for the rock-bottom price of $4.30. Here ya go, …read more

Improving Cheap Laser Engravers For PCB Fabrication

Posted on by

A few months ago, [Marco] picked up a cheap, cheap, cheap laser engraver from one of the familiar Chinese resellers. It’s a simple affair with aluminum extrusions, a diode laser, and a control board that seems like it was taken from a 3D printer controller designed five years ago. Now, [Marko] is building some upgrades for this engraver and his PCB production skills have gone through the roof.

The laser engraver [Marko] picked up is called the EleksMaker, and lucky for him there are quite a few upgrades available on Thingiverse. He found two 3D printable parts, one that keeps …read more

Exporting Eagle Libraries to FOSS Tools

Posted on by

Since Autodesk’s acquisition, Eagle has been making waves in the community. The de facto standard for Open Hardware PCB design is now getting push-and-shove routing, a button that flips the board over to the back (genius!), integration with Fusion360, automated 3D renderings of components, and a bunch of other neat tools. However, according to the community, Eagle is not without its warts, and there is a desire to port those innumerable Eagle board layouts and libraries to other PCB design packages. This tool does just that.

The tool is an extension of pcb-rnd, a FOSS tool for circuit board editing, …read more

Emulating A Forgotten UNIX Box

Posted on by

The AT&T 3B2 series of computers are historically significant, being the main porting platform for System V Release 3 UNIX. Unfortunately, the documentation for these computers has been nearly lost to the sands of time. They are, however, architecturally interesting machines, and [Seth Morabito] has been working for some time on reverse engineering them. Now, [Seth] is calling it: his AT&T 3B2/400 emulator is almost complete, resurrecting an ancient machine from the dead by studying UNIX source code.

The architecture of this computer is unlike anything you’ve seen before, but well-suited to a UNIX machine. The chipset is built around …read more

Copyright Exception May Overrule Ability To Jailbreak 3D Printers

Posted on by

At the end of October, the US Patent and Trademark Office renewed a rule allowing anyone to ‘jailbreak’ a 3D printer to use unapproved filament. For those of you following along from countries that haven’t sent a man to the moon, a printer that requires proprietary filament is DRM, and exceptions to the legal enforceability DRM exist, provided these exceptions do not violate US copyright law. This rule allowing for the jailbreaking of 3D printers contains an exception so broad it may overturn the rule.

A few months ago, the US Copyright Office renewed a rule stating that using unapproved …read more

Books You Should Read: The 3D Printing Handbook

Posted on by

3D printing was invented in the 80s, twenty years passed, patents expired, and then several diverse uses for 3D printing technology were found. As such, the tips and techniques for 3D printing — especially filament-based printing — have been discussed and documented almost entirely on the Internet, mostly in chat rooms, forums, and YouTube videos. Everything you could ever want to know about 3D printing is available on the Internet, but that doesn’t mean you’ll be able to find it.

There have been dozens of books published as a guidebook to 3D printing over the years, and some of those …read more

Hackaday Links: December 17, 2017

Posted on by

Where do you go if you want crazy old electronic crap? If you’re thinking a ham swap meet is the best place, think again. [Fran] got the opportunity to clean out the storage closet for the physics department at the University of Pennsylvania. Oh, man is there some cool stuff here. This room was filled to the brim with old databooks and development boards, and a sample kit for the unobtanium Nimo tube.

The Gigatron is a Hackaday Prize entry to build a multi-Megahertz computer with a color display out of TTL logic. Now, all this work is finally paying …read more

Friday Hack Chat: Eagle One Year Later

Posted on by

Way back in June of 2016, Autodesk acquired Cadsoft, and with it EagleCAD, the popular PCB design software. There were plans for some features that should have been in Eagle two decades ago, and right now Autodesk is rolling out an impressive list of features that include UX improvements, integration with MCAD and Fusion360, and push and shove routing.

Six months into the new age of Eagle, Autodesk announced they would be changing their licensing models to a subscription service. Where you could pay less than $100 once and hold onto version 6.0 forever, now you’re required to pay $15 …read more

Truly Terrible Dimensioned Drawings

Posted on by

I’m in the planning stages of a side project for Hackaday right now. It’s nothing too impressive, but this is a project that will involve a lot of electromechanical parts. This project is going to need a lot of panel mount 1/8″ jacks and sockets, vertical mount DIN 5 connectors, pots, switches, and other carefully crafted bits of metal. Mouser and Digikey are great for nearly every other type of electrical component, but when it comes to these sorts of electromechanical components, your best move is usually to look at AliExpress or DealExtreme, finding something close to what you need, …read more
