LEGO: The Kristiansen Legocy

Posted on by

Whether you are young, old, or a time traveling Vulcan, something unites all of us globally: the innocent LEGO blocks that encourage creativity over spoon-fed entertainment. Have you noticed the excess of zombified children and adults alike drooling over their collective screens lately? Back in the ancient times, all a child needed to create hours of joy were plastic interlocking bricks and a place for their parents to trip over them. The LEGO Group harbored the inspiration of our childhood inventiveness, and none of it would have been possible without the founder, Ole Kirk Kristiansen (or Christiansen). The humble carpenter …read more

360 Live VR Teleportation Uses Drones, Neural Networks, and Perseverance

Posted on by

This past semester I added research to my already full schedule of math and engineering classes, as any masochistic student eagerly would. Packed schedule aside, how do you pass up the chance to work on implementing 360° virtual teleportation to anywhere in the world, in real-time. Yes, it is indeed the same concept as the cult worshipped Star Trek transporter, minus the ability to physically be at the location. Perhaps we can add a, “beam me up, Scotty” command when shutting down.

The research lab I was working with it the Laboratory for Immersive CommunicatiON (LION). It’s funded by NSF, …read more

Tube Amps are Still Tubular in 2018

Posted on by

Our friend [Pete] was reminiscing over the golden days with his old and broken antique Grundig Majestic console when he realized it deserved proper refurbishing. Now, any generic stereo record player might not be worth the time and effort to fix, but this was not any generic stereo record player. [Pete’s] inherited Grundig Majestic was his childhood favorite due to the distinct sound it had from the tubes that were used as the active elements. So he set out to fix both tube amps inside of the system.

[Pete] has had some experience working with audio equipment in the past. …read more

The 348,296th Article About Cryptocurrency

Posted on by

The public has latched onto the recent market events with an intense curiosity brought about by a greed for instant riches. In the last year alone, the value of Bitcoin has risen by 1,731%. We’re talking gold rush V2.0, baby. Money talks, and with a resounding $615 billion held up in cryptocurrencies, it is clear why this is assuredly not the first cryptocurrency article you have read — maybe even today. An unfortunate side effect of mass interest in a subject is the wildfire-like spread of misinformation. So, what exactly is a blockchain, and what can you still do now …read more

Meet the Modern Meat Man’s Modified Meat-Safe

Posted on by

Charcuterie is delicious — but is it hackable? When talking about the salty preserved meats, one might be more inclined to indulge in the concept of bacon before pondering a way to integrate an electrical monitoring system into the process. However, [Danzetto] decided to do both when he did not have anywhere to cure his meats. He made his own fully automatic meat curing chamber lovingly called the curebOS with the aid of a raspberry pi. It is basically a beefed up mini fridge with all of the bells and whistles.

This baby has everything.  Sitting on top is a …read more

AMSAT MPPT Goes to Infinity and Beyond

Posted on by

AMSAT, the Radio Amateur Satellite Corporation, joined forces with students from Rochester Institute of Technology to create a MPPT attached to a Fox-1B CubeSat. It successfully launched into orbit on November 18th strapped to the back of a Delta II rocket. This analog MPPT, or Maximum Power Point Tracker, is used for optimizing the draw of a power cell in correspondence to the output of solar panels on the 10cm x 10cm satellite. In a nutshell, this works by matching the voltage of the two together. If you haven’t gotten a chance to play around with one of these first …read more

This DIY Turntable Just Got Freaky Fresh

Posted on by

Photography turntables are made for both the precise and lazy. Whether you are concerned about the precision of consistent angles during a photo shoot or you simply do not want to stand there rotating a plate after every picture — yes, it does get old — a lazy susan style automatic photography turntable is the ticket. This automatic 360° design made over at circuito.io satisfies both of these needs in an understated package. 

The parts required to make this DIY weekend project are about as minimal as they get. An Arduino Uno controls it all with a rotary encoder for …read more

LEDs Give HP 3457A DDM’s LCD Display the Boot

Posted on by

Have you ever been so frustrated with a digital display that you wanted to rip the whole thing out and create a better one? That is exactly what [xi] did. Replacing their constantly used HP 3457A multimeter’s LCD display with a brighter LED one was a necessary project — and a stress reducing one at that.

While this digital multimeter is well-known for its reliability, its standard display is rather lacking. In fact, there are several mods already out there that simply add a backlight. However, as [xi] notes, LCD screens always have a certain angle where they still don’t …read more

Blast From the Past with Space Station PROM Reader

Posted on by

The Ursa Major Space Station SST282 is a dinosaur of a digital reverb.  Okay, so maybe 1978 isn’t ancient yet, but it is getting to the point where one has to worry about the possibility of component failure.  At least that’s what [Obsoletetechnology] thought when they created a backup of its memory contents.

As can be seen from some of Hackaday’s previous articles, a part does not have to be an older one to fail.  However, there is no such thing as being too paranoid when it comes to older parts reaching their lifetime.  Especially when there is valuable …read more
