The hardware badge for the Hackaday Belgrade conference is a Retro Computer that you wear around your neck. I have one in my hands and it’s truly a work of art. It’s beautiful, it’s fun to play with, and it will be an epic platform for a glorious weekend of badge hacking! Check out the first look video, then join me below as I drill down into the details.
Get your ticket now for Hackaday Belgrade, our premier European hardware conference at the end of this month. It’s a day filled with talks, works, food, fun, and of course everyone …read more
At this point, you’ve almost certainly heard the tale of Eric Lundgren, the electronics recycler who is now looking at spending 15 months in prison because he was duplicating freely available Windows restore discs. Of no use to anyone who doesn’t already have a licensed copy of Windows, these restore discs have little to no monetary value. In fact, as an individual, you couldn’t buy one at retail if you wanted to. The duplication of these discs would therefore seem to be a victimless crime.
Especially when you hear what Eric wanted to do with these discs. To help extend …read more
Self-driving cars have been in the news a lot in the past two weeks. Uber’s self-driving taxi hit and killed a pedestrian on March 18, and just a few days later a Tesla running in “autopilot” mode slammed into a road barrier at full speed, killing the driver. In both cases, there was a human driver who was supposed to be watching over the shoulder of the machine, but in the Uber case the driver appears to have been distracted and in the Tesla case, the driver had hands off the steering wheel for six seconds prior to the crash. …read more
It’s depressingly easy to make bad videos, but it only takes a little care to turn that around. After ample lighting and decent audio — and not shooting in portrait — perhaps the biggest improvements come from stabilizing the camera while it’s moving. Giving your viewers motion sickness is bad form, after all, and to smooth out those beauty shots, a camera slider can be a big help.
Not all camera sliders are built alike, though, and we must admit to being baffled while first watching [Rulof Maker]’s build of a smooth, synchronized pan and slide camera rig. We just …read more
The computer security vulnerabilities Meltdown and Spectre can infer protected information based on subtle differences in hardware behavior. It takes less time to access data that has been cached versus data that needs to be retrieved from memory, and precisely measuring time difference is a critical part of these attacks.
Web browsers can’t change processor cache behavior, but they could take away malicious …read more
With apologies to Clement Clarke Moore, Richard Stallman, and the English-speaking world in general — ed.
‘Twas the night before Christmas
While up in my bed,
I stared at the ceiling
With feelings of dread.
I’d really no reason for portents of doom
Lying there, sleepless, in gathering gloom.
We’d wrapped all the presents, and decked out the tree,
But still, there was something niggling at me.
Then a stab of fear struck me, right through like a knife.
“Holy crap!” I exclaimed. “I FORGOT MY WIFE!”
Yes, somehow through all of the retail hell,
I’d forgotten to get …read more
Although we tend to think of 3D printers as high-tech toys, most of them are not especially powerful in the brain department. There are some exceptions, but most 3D printers run on either an 8-bit Arduino or some Arduino variant with a lot of I/O. There are a few 32-bit boards, but if you grab a random 3D printer, its brain is going to be an 8-bit AVR running something like Marlin or Repetier. It isn’t uncommon to see a Raspberry Pi connected to a printer, too, but — again, in general — it is a network interface that handles …read more
There are some notable figures in history that you know of for just one single thing. They may have achieved much in their lifetimes or they may have only been famous for Andy Warhol’s fifteen minutes, but through the lens of time we only know them for that single achievement. Then on the other hand there are those historic figures for whom there is such a choice of their achievements that have stood the test of time, that it is difficult to characterize them by a single one.
Such is the case of Isambard Kingdom Brunel, the subject of today’s …read more
Years ago, while the GPLv3 was still being drafted, I got a chance to attend a presentation by Richard Stallman. He did his whole routine as St IGNUcius, and then at the end said he would be answering questions in a separate room off to the side. While the more causal nerds shuffled out of the presentation room, I went along with a small group of free software aficionados that followed our patron saint into the inner sanctum.
When my turn came to address the free software maestro, I asked what advantages the GPLv3 would have to a lowly hacker …read more
Time zones have been a necessity since humans could travel faster than a horse, but with computers, interconnected over a vast hive of information, a larger problem has emerged. How do you keep track of time zones? Moreover, how do you keep track of time zones throughout history?
Quick question. If it’s noon in Boston, what time is it in Phoenix? Well, Boston is in the Eastern time zone, there’s the Central time zone, and Phoenix is in the Mountain time zone; noon, eleven, ten. If it’s noon in Boston, it’s ten o’clock AM in Phoenix. Here’s a slightly harder …read more
