The Intel Edison is out, and that means there’s someone out there trying to get a postage-stamp sized x86 machine running all those classic mid-90s games that just won’t work with modern hardware. The Edison isn’t the only tiny single board computer with an x86 processor out there; the legends told of another, and you can connect a graphics card to this one.
This build uses the 86Duino Zero, a single board computer stuffed into an Arduino form factor with a CPU that’s just about as capable as a Pentium II or III, loaded up with 128 MB of RAM, a PCI-e bus, and USB. It’s been a while since we’ve seen the 86Duino. We first saw it way back at the beginning of 2013, and since then, barring this build, nothing else has come up.
The 86Duino Zero only has a PCI-e x1 connector, but with an x16 adapter, this tiny board can drive an old nVidia GT230. A patch to the Coreboot image and a resistor for the Reset signal to the VGA was required, but other than that, it’s not terribly difficult to run old games on something the size of an Arduino and a significantly larger graphics card.
Thanks [Rasz] for sending this one in.

It’s pretty common to grab a USB webcam when you need something monitored. They’re quick and easy now, most are plug-and-play on almost every modern OS, and they’re cheap. But what happens when you need to monitor more than a few things? Often this means lots of cameras and additional expensive hardware to support the powerful software needed, but [moritz simon geist] and his group’s Madcam software can now do the same thing inexpensively and simply.
Many approaches were considered before the group settled on using PCI to handle the video feeds. Obviously using just USB would cause a bottleneck, but they also found that Ethernet had a very high latency as well. They also tried mixing the video feeds from Raspberry Pis, without much success either. Their computer is a pretty standard AMD with 4 GB of RAM running Xubuntu as well, so as long as you have the PCI slots needed there’s pretty much no limit to what you could do with this software.
At first we scoffed at the price tag of around $500 (including the computer that runs the software) but apparently the sky’s the limit for how much you could spend on a commercial system, so this is actually quite the reduction in cost. Odds are you have a desktop computer anyway, and once you get the software from their Github repository you’re pretty much on your way. So far the creators have tested the software with 10 cameras, but it could be expanded to handle more. It would be even cooler if you could somehow incorporate video feeds from radio sources!

Upgrading a desktop with a diamond cutting wheel
[Michail] needed a new graphics card. The only problem was his motherboard didn’t have any free PCI-E x16 slots available. Unable to find a PCI-E x1 card, he did what any of us would do and broke out the Dremel. Yes, he got it working, but don’t do this unless you know what you’re doing.
[Steve] recently got a Galaxy S3 and was looking for something to do with his old phone. It’s got WiFi, it’s got a camera, and with a free app, [Steve] now has an IP Webcam. Neat way to recycle a phone.
This is now bookmarked
We’re not much for plugging other blogs, but Math ∩ Programming – that’s intersection, remember – is really cool. Apparently it has been around for a little more than a year and already there are quite a few really cool posts. How to use cellular automaton to generate caves in video games and facial recognition through Eigenvalues are amazingly in depth, and show the theory behind some really cool techniques. Very, very cool.
Troll Physics: now wireless!
Remember [Fredzislaw100], the guy who puzzled the Internet with impossible circuits? He’s back again, this time with wireless LEDs. We’re guessing something similar to an induction charging system in the battery clip, wirelessly coupled to something under the paper, and that is wirelessly coupled to the LEDs. Your guess will probably be better than ours, though.

Pv2 [Zachary Ricks] of the U.S. Army thought we would get a kick out of the last name of one of the guys in his company. Yes, it’s ‘Hackaday,’ and yes, it’s a real surname. Here’s the full pic [Zach] sent in. Apparently it’s a name along the lines of ‘Holiday.’ Honestly, we had no idea this was a real surname, but we’re thinking Private Hackaday could use a care package or two (dozen).
Anyone up for sending a few hacker friendly (for [Zach] and a few other guys) care packages? Even socks or books or Oreos would make for an awesome care package. Email me if you want the mailing address.
