Kinect Visualizer Demo Gives Winamp A Run For Its Money

November 11, 2018 by Drew Littrell 9 Comments

Winamp eat your heart out, because thanks to the Microsoft Kinect in the hands of [Samarth] there’s a new way to make your screen dance along with you. He created a music visualizer demo that takes advantage of the 3D depth camera on Kinect by outputting a fun pixelated silhouette and color changing strobe. When there are big high-hat hits or bass thumps the camera feed reacts accordingly (as any good visualizer would). He even uploaded his code for the project just in case anyone would like to take a look at it.

The visualizer utilizes the OpenKinect-Processing library which has provided the backbone to many other similar Kinect art projects. It was specifically created to provide a quicker way for coders to access the raw color and depth data output by Kinect. It’s creator, Daniel Shiffman, has posted a number of tutorials to aid anyone looking to create their own real-time animations as well.

The visualizer demo (see video below) was created as part of Maker Faire Hyderabad which is happening over the weekend. The expo is the city’s first Maker Faire and is set to feature over 200 maker exhibits across multiple disciplines. It’s always great to see maker communities outside of the ones that are closest to you geographically speaking, so hopefully we’ll see many more like [Samarth] taking part in more maker events in the future.

NVIDIA 1060 with Udoo Single Board Computer

Single Board Computer Plays Nice With NVIDIA GPU

November 10, 2018 by Drew Littrell 39 Comments

It’s about convenience when it comes to single board computers. The trade-off of raw compute power for size means the bulk of them end up being ARM based, but there are a few exceptions like the x86 based Udoo Ultra. The embedded Intel 405 GPU on the Udoo Ultra is better than most in the category, but that won’t begin to play much of anything outside of a browser window. Not satisfied with “standard” [Matteo] put together his build combining an Udoo x86 Ultra with a NVIDIA 1060 GPU. It seems ridiculous to have an expansion card almost three times longer than the entire computer its attached to, but since when did being ridiculous stop anyone in the pursuit of a few more polygons?

M.2 adapter board trim comparison — M.2 to PCIe adapter board (Top) Trimmed adapter board (Bottom)

Since the Udoo Ultra doesn’t feature a PCIe slot [Matteo] slotted in a M.2 to PCIe adapter board. There are two PCIe lines accessible by the Udoo Ultra’s M.2 port although trimming the adapter board was required in order to fit. The PCIe female slot was cut open to allow the 1060 GPU to slide in. All of the throughput of the 1060 GPU wouldn’t be utilized given the Udoo Ultra’s limitations anyway.

Windows 10 was the OS chosen for the machine so that all those NVIDIA drivers could be installed, and there’s also the added benefit of being able to sneak in a little Trackmania Turbo too. So to accompany the build, [Matteo] created a graphics comparison video to show the remarkable improvement over the embedded graphics chip. You can see the Time Spy benchmark results in the video below.

What’s Inside That New Mac Mini Anyway?

November 10, 2018 by Drew Littrell 65 Comments

It’s been four long years since Apple has refreshed their entry-level desktop line. Those that have been waiting for a redesign of the Mac Mini can now collectively exhale as the Late 2018 edition has officially been released. Thanks to [iFixit] we have a clearer view of what’s changed in the new model as they posted a complete teardown of the Mac Mini over on their website.

One of the most welcomed changes is that the DDR4 RAM is actually user upgradeable this time around. Previously RAM was soldered directly to the motherboard, and there were no SO-DIMM slots to speak of. The 2018 Mac Mini’s RAM has also been doubled to 8GB compared to the 4GB in the 2014 model. Storage capacity may have taken a hit in the redesign, but the inclusion of a 128GB PCIe SSD in the base model fairs better than the 500GB HDD of old. The number of ports were flip-flopped between the two model generations with the 2018 Mini featuring four Thunderbolt ports along with two USB 3.0 ports. Though the biggest upgrade lies with the CPU. The base 2018 Mac Mini comes with a 3.6GHz quad-core Intel Core i3 as compared to the 2014’s 1.4GHz dual-core Intel Core i5.

Although Apple lacked “the courage” to drop the 3.5mm headphone jack this time around, they did retain the same footprint for Mac Mini redesign. It still provides HDMI as the default display out port, although the additional Thunderbolt ports provide additional options via an adapter. A quick overview of the spec differences between the 2018 and 2014 base Mac Mini models have been summarized below.

Model	2018 Mac Mini	2014 Mac Mini
CPU	3.6GHz quad-core Intel Core i3	1.4GHz dual-core Intel Core i5
Storage	128GB PCIe SSD	500GB HDD
RAM	8GB DDR4 @ 2666MHz	4GB DDR3 @ 1600MHz
Graphics	Intel UHD 630	Intel HD 5000
Ports	Thunderbolt 3 (x4), USB 3.0 (x2)	Thunderbolt 2 (x2), USB 3.0 (x4)
Card Slot	N/A	SDXC

How The Sony PlayStation Was Hacked

November 5, 2018 by Drew Littrell 34 Comments

Playgrounds were the comment sections of their day. Every weekday from exactly 1:17 PM until 1:43 PM there were swings to be swung, rumors to be spread, and debates to be settled by whomever was the loudest (some things never change). Allegiances were formed and battle lines were drawn based solely on what video game console you supported. It was this playground system that perpetuated the urban myths of the time.

For PlayStation fans there was the myth that you could save Aerith from her fate in Final Fantasy VII if you just cast the right spell, or the secret code in Tomb Raider that would let you see all of Lara Croft. There was the myth that no one could possibly copy a PlayStation game because all the bottoms of the discs were black. Even the very existence of the first PlayStation, the Super Nintendo PlayStation prototype, was an urban legend. The difference was that last one turned out to be true.

Let’s jump in and take a look at the cat and mouse game between modchip makers looking to defeat the original PlayStation’s copy protection, and Sony’s efforts to protect their castle.

LED Stick Person Costume Lights Up The Night

October 31, 2018 by Drew Littrell 16 Comments

Sometimes a simple idea can yield fantastic results. A few runs of LED strips fastened to a black hoody and sweatpants and just like that…a LED stick person costume for Halloween. The creator of the “Glowy Zoey” [Royce] originally put together some glow in the dark stick person suits to stand out when hitting the slopes at night. Now he’s taken that simple idea for a costume and made a small business out of it.

“I had a lot of extra parts laying around. I gathered everything up and got to work soldering.” – Royce Hutain

The suits themselves consist of button snaps and ribbon loops sewn into a pattern that routes the LED strips around the jacket’s hood and down each arm. To make the lighting effect pop, an all black plastic mask is used to cover the wearer’s face. It wouldn’t be that much a stretch to substitute EL wire in place of the LED strips if one were so inclined. We’d wager a number of you could pull this off straight out of the junkbox.

The Glowy Zoey stick figure suits even received some mainstream television press a few years ago when they were featured on Jimmy Fallon’s Late Night show. Note that visiting the Glowy Zoey website may take you back a bit since it features one of those autoplay jingles that were so prevalent in the Web 1.0 days. In fact the same jingle is used in the video below from their YouTube channel:

Prototype Proves Wii Was Two Gamecubes Taped Together All Along

October 29, 2018 by Drew Littrell 26 Comments

Say what you will about Nintendo’s little purple lunchbox, the GameCube, but it was home to many delightful experiences from Super Smash Bros. Melee to The Legend of Zelda: Twilight Princess. We now know it was also home to one of the very first Nintendo Wii remotes as well thanks to the recent listing from [Kuriaisu1122] on Yahoo Auctions.

The prototype Wii remote is a wired design and features a proprietary GameCube controller cable. Notable differences include the two buttons toward the bottom are labeled ‘B’ and ‘A’ respectively. This shows that Nintendo always intended to have players hold the remote sideways in order to play Virtual console games. The large white button next to the directional pad is unlabeled, and along the middle are the traditional ‘Start’ and ‘Select’ labels on either side of ‘Home’. However, these all would go through multiple revisions on the way to the final design. Interestingly there is an Ethernet jack at the base used to connect accessories. That connector would eventually become the often maligned “Nunchuk interface”, but what modder wouldn’t have loved it if that Ethernet port had carried on to the final design?

Parcelcopter Drone Project Delivers In Rough Terrain

October 29, 2018 by Drew Littrell 33 Comments

It’s a known fact that the last mile is also the longest mile in the parcel delivery service. The further removed from a hub city a delivery location is, the more required stops in between. Every part of the process slows to a glacial pace when the drop-off spot is inaccessible by land or air. Now apply this in the case of a medical emergency, and timing is everything.

Enter the joint project between [DHL and Wingcopter] dubbed Parcelcopter 4.0. The half plane, half helicopter drone design was recently tested over a six month period by making medical supply drops to Ukerewe island located in the middle of Lake Victoria. The remote island is home to roughly 400,000 people and many areas around the isle remain out of reach to traditional delivery vehicles. The island’s closest southern port is separated from mainland Tanzania by a four hour trip by barge and over six hours by road which makes drone delivery a potentially life saving option.

The Wingcopter drone itself is capable of vertical take off and landing (see 1:53 in the video below) while holding up to 9 lbs inside the thermally insulated cargo hold on the underside of the craft. It is controlled via 3G and/or 4G LTE, and according to the manufacturer website is capable of flying up to 60 miles on a single charge. Tests showed the drone made the nearly 40 mile trip across Lake Victoria in an average of 40 minutes.

It is interesting to see a real world commercial application seemingly ready to meet the needs of a vastly under served community. There are certainly many tests left to go before drone delivery goes into wider use, but thanks to this project the Parcelcopter 4.0 is 1400 air miles closer to that future.
