Hackaday Store Sale Ends Sunday!

Since the Hackaday Store Spring sale launched, hundreds of items have been flying out the door (sadly only metaphorically, not by drone delivery), and the warehouse robot uprising has been somewhat quelled.

But, all good things must come to an end. Sunday night, the big discounts will disappear and regular prices will return. Until then you can get up to 30% off a range of electronics toys, hardware tools, DIY kits, and Sparkfun items.

Tiny BLE UART Makes Bluetooth Low Energy Simple

Last time I talked about the internals of how Bluetooth Low Energy (BLE) handles data. I mentioned that the way it is set up is meant to conserve power and also to support common BLE devices like heart rate monitors. On the other hand, I also mentioned that you often didn’t need to deal with that because you’d use an abstraction layer.

This time, I want to show you how I used the Hackaday special edition Tiny BLE (from Seeed Studios) and its mbed library to do a quick simple BLE project. If you didn’t read the first part, don’t worry. The abstraction is so good, you probably won’t have to unless you want to circle back around later and get a more detailed understanding of what’s happening under the covers.

I wanted something simple for an example so you could build on it without having to remove much code. For that reason, I decided to allow my phone to control the state of a three-color LED via BLE. To do that, I’m going to use a virtual UART and some off-the-shelf phone software. The whole thing won’t take much code, but that’s the point: the abstraction makes BLE relatively simple.

The Hackaday 2015 Omnibus: A Puzzle So Dense, Even We Don’t Know The Answer

Print is dead, so we put a skull on it. That’s the philosophy behind the 2015 Hackaday Omnibus, the printed collection of the best Hackaday has to offer.

We have a few ideas of where we would like to take the print edition of Hackaday. Mad magazine-style fold-ins are on the list, specifically a fold-in style schematic that does two completely different things. Remember when records were included as a magazine insert? Those are called flexi-discs, and there’s exactly one company that still does it. All of these and more are plans for the future, and for the 2015 Hackaday Omnibus, we chose to include something we’re all very familiar with: a puzzle. This is no ordinary puzzle – even we don’t know what the solution is.

An Omnibus In Every Stocking

We know that hackers like to procrastinate. But right now is the limit. This is the last day you can order the Omnibus Volume 2 and have it (most likely) in your hands in time to put one in everyone’s stocking. Tomorrow will be too late.

Take advantage of the promo code which expires at the end of tomorrow. Use coupon code OMNIBUS2015 and get $7 off the price. There were 100 of those codes left at the time of writing.

What is the Omnibus all about? Check out [Brian’s] explanation of what makes the Omnibus so special. This body of work is a huge achievement and I’m proud that we’re able to recognize the effort of everyone here at Hackaday with something you hold in your hands which will live forever.

Hackaday’s Omnibus Vol. 2, Now In Stock

Last month, we announced a preorder for volume two of the Hackaday Omnibus, a collection of content written over the course of this year that is the best we have to offer. Now, there is a warehouse full of deceptively heavy boxes, and the Hackaday Omnibus Vol. 2 is now in stock.

bus9Inside the second edition of the Hackaday Omnibus is 128 pages of actual, real content. There are zero ads, no sponsored content, and absolutely nothing that tells you to go out and buy something. Opening it is an experience unlike anything. Where can you read something for minutes at a time with no interruptions, no email, no Twitter, no Facebook, no text messages, and no ads? You won’t find something like this anywhere else.

The electronics, trade, and tech magazines have a long and storied history. In the 1930s, there were magazines that would teach you how to build a radio. In the 1950s, there were print articles saying fusion power was just fifty years away. The Hackaday Omnibus continues this tradition with relevant content for today: everything from car hacking and open source insulin, to retrospectives on oft-forgotten parts of our digital heritage are included. This is the best we have to offer, and we’re doing it without selling out.

Volume Two of the Hackaday Omnibus isn’t the end for our print endeavours – we’re just getting started. We’re committed to producing the best content in an interruption-free format. Print is dead, after all, and that’s why we put a skull on it.

You can purchase the Hackaday Omnibus Volume Two on the Hackaday Store.

Pre-order this Graphically Stunning Print Edition of Hackaday

Now is your chance to hold a piece of Hackaday in your hands. Last year we announced our first ever print edition. We continue that tradition with a much bigger offering. Hackaday Omnibus vol #02 gathers the best content from Hackaday over the last year. This includes in-depth original content, incredible art, the events that mattered over the last 12 months, and a few cryptic easter eggs.

omnibus-vol2-on-your-coffee-table[Joe Kim], Hackaday’s Art Direct, really outdid himself with the cover this year. Inspired by an epic movie, the illustration includes a shoutout to almost every article found within. Of course there is a lot more of his work inside, along with the efforts of dozens of writers, artists, editors, and more.

All 128 pages of Omnibus vol #02 were painstakingly laid out by [Aleksandar Bradic] who enlisted the help of a dedicated core of Hackaday.io members to help pore over the final drafts, ensuring the presentation is immaculate. Along the way some of them teamed up to roll in those easter eggs that I previously mentioned. We don’t even know what all of it means, you should be the first to solve the mystery.

Most of the 31 articles that grace these pages have run past the front page of Hackaday. But there are a few that were written specifically for the print edition. These will be published on our front page starting in 90 minutes and continuing for a few weeks. It is important to us to share these great works without the need to purchase anything. But the Omnibus is truly one of the coolest pieces of tech literature that you can own. It deserves a place on your coffee table, reception area at work, and as a gift for all who love to know how things work, how things were built, and the legacy of knowledge that has come from generations of hacking.

We’re only running a single printing of this gorgeous volume. Make sure you get one of your own by placing a pre-order now. Be one of the first 500 using coupon code OMNIBUS2015 and get it for just $10! Show that you support great content and help make future projects like this possible.
