It’s hard to beat the fidelity and durability of printed text on paper. But the e-paper display gets pretty close, and if you couple it will great design and dependable features, you might just prefer an e-reader over a bookshelf full of paperbacks. What if the deal is sweetened by making it Open Hardware? The Open Book Project rises to that challenge and has just been named the winner of the Take Flight with Feather contest.
This e-reader will now find its way into the wild, with a small manufacturing run to be put into stock by Digi-Key who sponsored this contest. Let’s take a closer look at the Open Book, as well as the five other top entries.
The old way was to write clever code that could handle every possible outcome. But what if you don’t know exactly what your inputs will look like, or just need a faster route to the final results? The answer is Machine Learning, and we want you to give it a try during the Train All the Things contest!
It’s hard to find a more buzz-worthy term than Artificial Intelligence. Right now, where the rubber hits the road in AI is Machine Learning and it’s never been so easy to get your feet wet in this realm.
From an 8-bit microcontroller to common single-board computers, you can do cool things like object recognition or color classification quite easily. Grab a beefier processor, dedicated ASIC, or lean heavily into the power of the cloud and you can do much more, like facial identification and gesture recognition. But the sky’s the limit. A big part of this contest is that we want everyone to get inspired by what you manage to pull off.
Yes, We Do Want to See Your ML “Hello World” Too!
Wait, wait, come back here. Have we already scared you off? Don’t read AI or ML and assume it’s not for you. We’ve included a category for “Artificial Intelligence Blinky” — your first attempt at doing something cool.
Our guess is you don’t really need prizes to get excited about this one… most people have been itching for a reason to try out machine learning for quite some time. But we do have $100 Tindie gift certificates for the most interesting entry in each of the four contest categories: ML on the edge, ML on the gateway, AI blinky, and ML in the cloud.
Hackaday editors Elliot Williams and Mike Szczys work their way through a dizzying maze of great hacks this week, bringing you along for the ride.
We take a look at simplifying home automation with Node-RED and marvel at the misuse of the SED — Linux’s stream editor for filtering and transforming text — to find your way through a maze. Have the hippest portable; grab your really old Apple laptop and stuff a not-so-old Apple desktop inside. We bring it on home with our love (or hate?) for the resistor color code.

For years we’ve seen a trickle of really interesting home automation projects that use the Node-RED package. Each time, the hackers behind these projects have raved about Node-RED and now I’ve joined those ranks as well.
This graphic-based coding platform lets you quickly put together useful operations and graphic user interfaces (GUIs), whether you’re the freshest greenhorn or a seasoned veteran. You can use it to switch your internet-connected lights on schedule, or at the touch of a button through a web-app available to any device on your home network. You can use it as an information dashboard for the weather forecast, latest Hackaday articles, bus schedules, or all of them at once. At a glance it abstracts away the complexity of writing Javascript, while also making it simple to dive under hood and use your 1337 haxor skills to add your own code.
You can get this up and running in less than an hour and I’m going to tackle that as well as examples for playing with MQTT, setting up a web GUI, and writing to log files. To make Node-RED persistent on your network you need a server, but it’s lean enough to run from a Raspberry Pi without issue, and it’s even installed by default in BeagleBone distributions. Code for all examples in this guide can be found in the tutorial repository. Let’s dive in!
Hackaday editors Mike Szczys and Elliot Williams sort through all of the hacks to find the most interesting hardware projects you may have missed this week. Did you know you can use machine learning without a neural network? Here’s a project that does that on an ATtiny85. We also wrap our minds around a 3D-printed press brake, look at power-saving features of the ESP32 that make it better on a battery, and discuss the IoT coffee maker hack that’s so good it could be a stock feature. Plus we dive into naturally occurring nuclear reactors and admire the common, yet marvelous, bar code.

Join Hackaday in Belgrade, Serbia on May 9th, 2020 for the Hackaday Belgrade conference! The biennial hardware conference is just seventeen weeks from now. Early Bird tickets will go on sale shortly, but beginning right now you can hack your way into the conference by submitting a talk proposal. Accepted speakers receive free admission, plus everyone who submits a quality talk proposal will be given priority when tickets go on sale.
Yes, I’m talking to you. Hackaday strives to include first-time speakers in the slate of presenters at our conferences. We’re looking for unique, cutting-edge, whimsical, crazy, formidable, or world-changing topics revolving around hardware creation. From learning new tools or techniques to fabrication adventures, from code-wrangling that firmware project to pulling off an art installation, and from forgotten hardware history to the impossible made possible on your own workbench, we need to hear your stories!
That project for which you went into the deep weeds and worked your way back out again? Everyone at a Hackaday conference wants to hear about it and in the greatest detail possible. After all, we’re your fellow hackers. In fact, you should probably bring the hardware along for the ride.
We Need You
None of this happens in a vacuum. This is the third Hackaday Belgrade conference, which have now settled into a tick-tock cadence of even-numbered years. The first two both sold out, this one will as well, and the result is always an action-packed, nearly 24-hour marathon sprint of talks, workshops, and hardware hacking. But the only reason this works is because amazing people just like you make it a priority in their life to be there.

So take the plunge, put together your talk proposal and submit it before March 2nd. But don’t stop there, pester your friends and your heros to do the same. Block out May 9th on your schedule (roughly 9 am-2 am) and take the day before off of work. While you’re at it, convince your boss and coworkers to come along with you. See you in Belgrade!
Let’s be honest, Ruth Grace Wong can’t teach you how to be a manufacturing engineer in the span of a twenty minute talk. But no-one can. This is about picking up the skills for a new career without following the traditional education path, and that takes some serious time. But Grace pulled it off, and her talk at the 2019 Hackaday Superconference shares what she learned about reinventing your career path without completely disrupting your life to do so.
Ruth got on this crazy ride when she realized that being a maker made her happy and she wanted to do a lot more of it. See wanted to be “making stuff at scale” which is the definition of manufacturing. She took the hacker approach, by leveraging her personal projects to pull back the veil of the manufacturing world. She did a few crowd funding campaigns that exposed her to the difficulties of producing more than one of something. And along the way used revenue from those projects to get training and to seek mentorships.
