Hackaday Links: December 2, 2018

CircuitPython is becoming a thing! CircuitPython was originally developed from MicroPython and ported to various ARM boards by Adafruit. Now, SparkFun is shipping their own CircuitPython board based on the nRF52840, giving this board an ARM Cortex-M4 and a Bluetooth radio.

You like contests, right? You like circuit boards too, right? Hackster.io now has a BadgeLove contest going on to create the Blinkiest Badge on Earth. Yes, this is a #badgelife contest, with the goal of demonstrating how much you can do in a single circuit badge. Prizes include a trip to San Francisco, a badass drone, a skateboard, a …read more

Creating KiCad Parts From A PDF Automagically

For anyone out there who has ever struggled finding a part for Eagle or KiCad, there are some who would say you’re doing it wrong. You’re supposed to make your own parts if you can’t find them in the libraries you already have. This is really the only way; PCB design tools are tools, and so the story goes you’ll never be a master unless you can make your own parts.

That said, making schematic parts and footprints is a pain, and if there’s a tool to automate the process, we’d be happy to use it. That’s exactly what …read more

Advanced Techniques For Using Git With KiCAD

For most developers “distributed version control” probably means git. But by itself git doesn’t work very well with binary files such as images, zip files and the like because git doesn’t know how to make sense of the structure of an arbitrary blobs of bytes. So when trying to figure out how to track changes in design files created by most EDA tools git doesn’t get the nod and designers can be trapped in SVN hell. It turns out though KiCAD’s design files may not have obvious extensions like .txt, they are fundamentally text files (you might know that if …read more

Visual Schematic Diffs in KiCAD Help Find Changes

When writing software a key part of the development workflow is looking at changes between files. With version control systems this process can get pretty advanced, letting you see changes between arbitrary files and slices in time. Tooling exists to do this visually in the world of EDA tools but it hasn’t really trickled all the way down to the free hobbyist level yet. But thanks to open and well understood file formats [jean-noël] has written plotgitsch to do it for KiCAD.

In the high(er)-end world of EDA tools like OrCAD and Altium there is a tight integration between the …read more

Another holy scroll for the Church of Robotron. PoC || GTFO is a semi-annual journal of hardware exploitation, and something you must read. About a year ago, No Starch Press released the first Bible of PoC || GTFO, and now it’s time for a new testament. PoC || GTFO Volume 2 is out now, covering Elegies of the Second Crypt War to Stones from the Ivory Tower, Only as Ballast. It’s still Bible-shaped, with a leatherette cover and gilt edges.

KiCad version 5 is out, and you know what that means: It’s time to start on version 6. To …read more

Hackaday Links: July 22, 2018

KiCad Version 5 has been released! Footprints are going to be installed locally, and the Github plugin for library management is no longer the default. You now have the ability to import Eagle projects directly, Eeschema has a better configuration dialog, better wire dragging, and Pcbnew now has complex pad shapes. The changelog also says they’ve gone from pronouncing it as ‘Kai-CAD’ to ‘Qai-CAD’.

Kids can’t use computers because of those darn smartphones. Finally, the world is ending not because of Millennials, but because of whatever generation we’re calling 12-year-olds. (I’m partial to Generation Next, but that’s only because my …read more

Build Your Own Android Smartphone

Let’s get this out of the way first – this project isn’t meant to be a replacement for your regular smartphone. Although, at the very least, you can use it as one if you’d like to. But [Shree Kumar]’s Hackaday Prize 2018 entry, the Kite : Open Hardware Android Smartphone aims to be an Open platform for hackers and everyone else, enabling them to dig into the innards of a smartphone and use it as a base platform to build a variety of hardware.

When talking about modular smartphones, Google’s Project Ara and the Phonebloks project immediately spring to mind. …read more

When Detecting Lines Is Harder Than Expected

[Conor Patrick] is no stranger to hardware development, and he’s had an interesting project for the past few months. He’s attempting to create a tool to convert images of technical drawings (such as footprints for electronic components) into digital formats that can be imported into other tools. This could automate turning a typical footprint drawing like the one shown into an actual part definition in a CAD program, which could really speed up the creation of custom parts.

Key to the entire concept is the detection of lines in a black-and-white technical drawing. To some people this won’t sound like …read more

Hackaday Links: February 25, 2018

Hipster hardware! [Bunnie] found something interesting in Tokyo. It’s a LED matrix display, with a few PDIP chips glued onto the front. There are no through-holes or vias, and these PDIPs can’t be seen through on the back side of the board. Someone is gluing retro-looking chips onto boards so it looks cool. It’s the ‘gluing gears to everything therefore steampunk’ aesthetic. What does this mean for the future? Our tubes and boxes of 74-series chips will be ruined by a dumb kid with a hot glue gun when we’re dead.

Is it Kai-CAD or Key-CAD? Now you can …read more

These Small PCBs are Made for Model Rocketry

Model rocketry hobbyists are familiar with the need to roll their own solutions when putting high-tech features into rockets, and a desire to include a microcontroller in a rocket while still keeping things flexible and modular is what led [concretedog] to design a system using 22 mm diameter stackable PCBs designed to easily fit inside rocket bodies. The system uses a couple of 2 mm threaded rods for robust mounting and provides an ATTiny85 microcontroller, power control, and an optional small prototyping area. Making self-contained modular sleds that fit easily into rocket bodies (or any tube with a roughly one-inch …read more
