Digitizing Domesday Disks

After the Norman invasion of England, William the Conqueror ordered a great reckoning of all the lands and assets owned. Tax assessors went out into the country, counted sheep and chickens, and compiled everything into one great tome. This was the Domesday Book, an accounting of everything owned in England nearly 1000 years ago. It is a vital source for historians and economists, and one of the most important texts of the Middle Ages.

In the early 1980s, the BBC set upon a new Domesday Project. Over one million people took part in compiling writings on history, geography, and social …read more

VCF East XIII: Another Day in Retro Paradise

While the weather alternated between mist and monsoon for most of it, the thirteenth annual Vintage Computer Festival East was still a huge success. People came from all over the country, and indeed the world, to show off computers and equipment that was easily older than many of those in attendance. From 1980’s robots to recreations of the very first machines to ever carry the name “computer” as we understand it today, there were a dizzying array of fascinating exhibits to see for those who made the pilgrimage to the InfoAge Science Center in Wall, New Jersey. The people who …read more

Friday Hack Chat: Hacking The Wild

It’s nearly summer, and that means we’re right at the start of conference season, at least for the tech and netsec crowd. Conferences, if you’re not aware, are a conspiracy for the hotel-industrial complex and a terrible way to spend thousands of dollars on a crappy hotel room and twenty-five dollar hamburgers.

[Andrew Quitmeyer] is working on an experimental academic conference that might just put an end to the horrors of conference season. He’s creating his own conference called Dinacon, and it’s going to be cheaper to attend, even though it’s on a tropical island in the Pacific.

For this …read more

A Wild Hackaday Belgrade Confirms Status as One of World’s Greatest Hardware Cons

Hackers, Designers, and Engineers flooded into Dom Omladine on Saturday for what can only be described as an epic celebration of hardware culture. This is the second time Hackaday has organized a huge conference in Belgrade, and lightning really did strike twice.

A Gathering of New Friends and Old

We got things started off with a meetup the night before the conference. The first Hackaday Belgrade was held in 2016 and we didn’t reserve a bar on Friday night — we ended up taking over one just through sheer numbers. This year we called ahead for a large outdoor space, …read more

Hackaday Belgrade 2018 is Sold Out: We Can’t Wait for Saturday

Greetings from beautiful Belgrade! With the Hackaday crew arriving over the last couple of days, preparations are in full swing, and the excitement is building for Hackaday Belgrade 2018 on Saturday. Here’s all the news you need to know.

If you haven’t gotten tickets yet, you can’t say we didn’t warn you! We’ve sold out. But don’t despair: there’s a waitlist, so get your name in now if you still want to get in.

  • The final conference schedule has just been released and it’s super.
  • We’re having a meetup Friday night at 20:00 at the Bajloni Bar and Beyond, join

Double The Resolution, From An Arduino ADC

Analog-to-digital converters, or ADCs, are somewhat monolithic devices for most users, a black box that you ask nicely for the value on its input, and receive a number in return. For most readers, they will be built into whatever microcontroller is their platform of choice, and their resolution will be immutable, set by whatever circuitry is included upon the die. There are a few tricks that can be employed to get a bit more from a stock ADC though, and [Neris] has taken a look at a couple of them.

The first circuit doubles the resolution of an ADC, in …read more

Hardware Acceleration in the Cloud

Computers are great at a lot of things. However, general-purpose computers can benefit from help on certain tasks, which is why your video card and sound card both have their own specialized hardware to offload the CPU. If Accelize has its way, some of your hardware acceleration will be done in the cloud. Yes, we know. The cloud is the buzzword of the week and we are tired of hearing about it, too. However, this service is a particularly interesting way to add FPGA power to just about any network-connected CPU.

Currently, there are only four accelerators available, including a …read more

Home Made 5-Axis CNC Head Is A Project To Watch

[Reiner Schmidt] was tired of renting an expensive 5-axis CNC head for projects, so he decided to build his own. It’s still a work in progress, but he’s made remarkable progress so far. The project is called Bridge Boy, and it is designed to use a cheap DC rotary mill to cut soft materials like plastic, wood and the like. Most of it is 3D printed, and he has released the Autodesk 360 plans that would allow you to start building your own. His initial version uses an Arduino with stepper drivers, and is designed to fit onto the end …read more

One-Pixel Attack Fools Neural Networks

Deep Neural Networks can be pretty good at identifying images — almost as good as they are at attracting Silicon Valley venture capital. But they can also be fairly brittle, and a slew of research projects over the last few years have been working on making the networks’ image classification less likely to be deliberately fooled.

One particular line of attack involves adding particularly-crafted noise to an image that flips some bits in the deep dark heart of the network, and makes it see something else where no human would notice the difference. We got tipped with a YouTube video …read more

You Don’t Need to be Tony Stark to Afford This Hand Controller

Proving that duct tape really can do anything, [StudentBuilds] uses it to make a workable controller out of a glove. To be fair, there are a few more bits too, including paper coated with pencil graphite and tin foil, which forms a variable resistor you can read with an Arduino analog input. You can see the entire thing in the video below.

The source code is simple at this point — eventually, he plans to control a robotic hand with the controller, but that’s later. However, there’s no promised link to the code in the description, so you’ll have to …read more
