You want a good project that combines multiple disciplines, gives you something useful in the end, and will certainly wow the muggles? Or do you simply need a custom rig with which to “jack in” to “cyberspace”? How about building your own luggable, portable, computer with some style — your own cyberdeck?

Coming to you from the fertile world that William Gibson created in “Neuromancer”, “Count Zero”, and “Mona Lisa Overdrive”, cyberdecks were the portable computers that the heroes and anti-heroes roaming the Sprawl would use to connect to what was essentially the Internet. Since we’re already living in the era where large portions of the world are controlled by vast corporations, we spend our entire lives online, and machine intelligence is poised to become sentient, you might as well get building.

We’ve seen a number of great examples of cyberdeck builds, and they’re all special in their own way, but there are common features uniting them all. First, you’ll need a screen, a portable computer brain, some batteries, and a nice keyboard. The good news is that all of the above have become eminently available, even inexpensive, in the last few years.

Discipline #1 is that of the case modder. You’re designing your ideal portable computer, after all. It’s got to look good, and we don’t mean that black, boxy ThinkPad look. If you’ve got a 3D printer, and maybe a willingness to spray paint, the world is your oyster here.

Discipline #2 is that of the keyboard builder. You’re not going to want to enter the Matrix with anything less than a pleasant typing interface. Again, 3D printing, laser-cutting, or CNC milling your own keyplate and building yourself a keyboard from scratch is a viable option, but there are tons of Bluetooth and USB keyboard options if you want to cut corners, or find one you really like.

Discipline #3 is the software hacker. Putting together exactly the right set of software, setting up the system to do what you want, and getting that sweet background screen just right are the last steps to making yourself at home in Cyberspace.

With so much latitude to introduce your own design ideas into your bespoke luggable, no two will be alike. Mine’s going to have programming ports for every microcontroller I frequently use, a decent speaker, maybe a variable power supply, and probably some reasonable amount of LED bling. What’s going to be on yours?

Hackaday Podcast 070: Memory Bump, Strontium Rain, Sentient Solder Smoke, And Botting Browsers

June 5, 2020 by Mike Szczys No comments

Hackaday editors Elliot Williams and Mike Szczys bubble sort a sample set of amazing hacks from the past week. Who has even used the smart chip from an old credit card as a functional component in their own circuit? This guy. There’s something scientifically devious about the way solder smoke heat-seeks to your nostrils. There’s more than one way to strip 16-bit audio down to five. And those nuclear tests from the 40s, 50s, and 60s? Those are still affecting how science takes measurements of all sorts of things in the world.

Take a look at the links below if you want to follow along, and as always, tell us what you think about this episode in the comments!

This Week In Security: Exim, Apple Sign-in, Cursed Wallpaper, And Nuclear Secrets

June 5, 2020 by Jonathan Bennett 9 Comments

So first off, remember the Unc0ver vulnerability/jailbreak from last week? In the 13.5.1 iOS release, the underlying flaw was fixed, closing the jailbreak. If you intend to jailbreak your iOS device, make sure not to install this update. That said, the normal warning applies: Be very careful about running out-of-date software.

Apple Sign In

An exploit in Apple’s web authentication protocol was fixed in the past week . Sign In With Apple is similar to OAuth, and allows using an Apple account to sign in to other sites and services. Under the hood, a JSON Web Token (JWT) gets generated and passed around, in order to confirm the user’s identity. In theory, this scheme even allows authentication without disclosing the user’s email address.

So what could go wrong? Apparently a simple request for a JWT that’s signed with Apple’s public key will automatically be approved. Yeah, it was that bad. Any account linked to an Apple ID could be trivially compromised. It was fixed this past week, after being found and reported by [Bhavuk Jain].

3D Printering: Sticky Resin Prints And How To Fix Them

June 4, 2020 by Donald Papp 39 Comments

After going through all the trouble of printing a part in resin, discovering it feels sticky or tacky to the touch is pretty unwelcome. Giving the model some extra ultraviolet (UV) curing seems like it should fix the problem, but it probably does not. So, what can be done?

The best thing to do with a sticky print is to immediately re-wash it in clean isopropyl alcohol (IPA) before the UV present in ambient light cures stray resin. If the part remains sticky after it is dry, more aggressive steps can be taken.

We’ll get into those more extreme procedures shortly, but first let’s understand a bit more about how resin works, then look at how that applies to preventing and removing tacky surfaces on finished prints. Continue reading “3D Printering: Sticky Resin Prints And How To Fix Them” →

Hackaday Prize And UCPLA Are Driving Assistive Technology Forward

June 3, 2020 by Kristina Panos 1 Comment

Take a second to imagine all the people in your life. Your family, friends, coworkers. Your buddies down at the hackerspace, and anyone you chat with on IO and over the airwaves. Statistically speaking, one in four of these people has a disability of some kind, and needs help doing everyday things that you might not think twice about — simple things like opening doors or interacting with computers. Or maybe that one in four is you.

For the past 75 years, United Cerebral Palsy of LA (UCPLA) have been helping people with various developmental and intellectual disabilities to live independently with dignity. They work directly with members of the disabled community to develop assistive technology that is both affordable and dependable. UCPLA helps the disabled community with everything from employment to providing a creative outlet, and gives them the tools to do these things and more. Their mission is to help people be as independent as possible so they can feel good about themselves and enjoy a life without limits.

The people behind this non-profit are all about inclusion, access, and opportunity, and this is why we are proud to partner with UCPLA for the 2020 Hackaday Prize. With the world in upheaval, there is no better time to build a better future for everyone. You never know when you might need assistive technology. In addition to the open challenge that calls for everyone to work on a design, this year there is also a Dream Team challenge which offers a $3,000 per month stipend over the next two months to work on a team addressing one specific challenge. Apply for that asap!

What kind of challenges has UCPLA outlined for the Hackaday Prize? Let’s dive in and find out, and we’ll also hear from the UCPLA team in a Q&A video at the end of the article.

Surviving The Pandemic As A Hacker: Peering Behind The Mask

June 3, 2020 by Jenny List 30 Comments

We’re now several months into the global response to the COVID-19 pandemic, with most parts of the world falling somewhere on the lockdown/social distancing/opening up path.

It’s fair to say now that while the medical emergency has not passed, the level of knowledge about it has changed significantly. When communities were fighting to slow the initial spead, the focus was on solving the problem of medical protection gear and other equipment shortages at all costs with some interesting yet possibly hazardous solutions. Now the focus has moved towards protecting the general public when they do need to venture out, and as society learns to get life moving again with safety measures in place.

So, we all need masks of some sort. What type to do you need? Is one type better than another? And how do we all get them when everyone suddenly needs what was once a somewhat niche item?

Inputs Of Interest: ErgoDox Post-Mortem

June 2, 2020 by Kristina Panos 18 Comments

In the last installment, I told you I was building an open-source, split, ortholinear keyboard called the ErgoDox. I’m doing this because although I totally love my Kinesis Advantage, it has made me want to crack my knuckles and explore the world of split keyboards. Apparently there are several of you who want to do the same, as evidenced by your interest in the I’m Building an ErgoDox! project on IO. Thank you!

Well boys and girls, the dust has settled, the soldering iron has cooled, and the keycaps are in place. The ErgoDox is built and working. Now that it’s all said and done, let me tell you how it went. Spoiler alert: not great. But I got through it, and it keyboards just like it’s supposed to. I’m gonna lay this journey out as it happened, step by step, so you can live vicariously through my experience.
