We met up with Freescale guy [Witek] at our party in Munich last year, and he wrote in to tell us about the Freescale booth at Embedded World this week in Nuremberg. They’re going to have a bunch of Freedom boards to play around with and an extremely powerful RIoTboard with a 1GHz iMX6 Solo processor, 1GB of RAM, and 4GB of EMMC Flash. It’s not a Raspi or BeagleBone killer, but if you need a small Linux board with a lot of horsepower, there ‘ya go.
SmarterEveryDay is finally getting around to doing a series of videos about space. This guy knows his stuff, and with the access he can get, it should make for interesting viewing.
Here’s something for your Sunday listening: [Vint Cerf] at Carnegie Mellon talking about the Olive Project and the Interplanetary Internet. The Olive project is an archive for executables, and solves the problem of having to preserve hardware along with software. Cool stuff.
10 GHz pulse magnetron destroys electronics. That’s the only information you’re going to get with this one. There’s a fine line between ‘don’t try this at home’ and ‘this project needs replication’.
Most of the northern half of the United States is covered in a billion tons of snow. [Jamie]’s electric snowmobile/Power Wheels is the perfect vehicle for this occasion. It’s 36V with two 500W motors. Figure out how to replace the wheels with small treads, and there’s really something interesting here.
[Matthias Wandel], also known as the genius/demigod that can make anything out of wood, put together a mount for a Raspberry Pi and a camera. Yes, it’s just a holder for a Raspi, but some of our readers who aren’t up to speed with [Matthias] might want to check out his Youtube channel. There are hundreds of awesome videos. Report back in a month.
[Evan], the guy working his butt off for the MidAtlantic Retro Computing Hobbyists, and the organizer for the Vintage Computer Festival East (we’re going, April 17-19, Wall, NJ) has been working on a book. It’s about mobile computing, and he’s crowdfunding it.
Your keyboard has buttons, and so does and Akai MPC. Daft PunKonsole! Press the space bar for instrumental part. There is, as yet, no video of someone doing this correctly.
Valentine’s Day was yesterday, and that means Valentine’s Day builds started rolling in on the tip line. Here’s something that’s actually a very simple circuit that’s inspired from an old ‘Electronic Games and Toys’ book by [Len Buckwalter]. Here’s a video of it in action.
A few years ago the name of the game was tiny, credit card-sized ARM boards. It had to come to this: a 64-bit board. ARM Cortex A53 running at 1.2GHz. It also costs $120 and only has a gig of RAM, but there you go.
[CNLohr] is famous for his extremely strange projects, including something that does something with Minecraft that even he can’t describe. Over the years, he’s built up a vast collection of projects that have been both incredible fails and successes. Here’s a video tour of all those projects.
For this week’s edition “Kickstarter is going insane”, you only need to look at the title of the campaign: Tesla Coils for North Korea.
Last week, a few slow scan TV signals were received from the International Space Station. Here’s the reddit thread.
The worst thing about using an Arduino in a semi-professional environment is the IDE. Here’s cuwire, a better IDE.
Wanna see something insane? How about an SSH library written in x64 assembly?
Radio Shack is in its death throes, and since you haven’t gone in the last few years, you might as well head out one last time and pick up some items on clearance. Here’s the list of store closings (PDF) and all 1,784 stores slated to be closed plotted on Google Maps.
It’s Sunday evening, and that means Hackaday Links, and that means something crowdfunded. This week it’s UberBlox. It’s a modular construction system based on Al extrusion – basically a modern version of an Erector set. Random musings on the perceived value UberBlox offers in the comments, I’m sure.
[Trevor] sent in something from his Etsy shop. Normally we’d shy away from blatant self-promotion, but this is pretty cool. It’s reproductions of 1960s Lockheed flying saucer plans. We’re not sure if this is nazi moon base/lizard people from the inner earth flying saucer plans or something a little more realistic, but there you go.
3D computer mice exist, as do quadcopters. Here’s the combination. It looks like there’s a good amount of control, and could be used for some aerobatics if you’re cool enough.
Who doesn’t love LED cubes? They’re awesome, but usually limited to one color. Here’s an RGB LED cube. It’s only 4x4x4, but there’s a few animations and a microphone with a beat detection circuit all powered by an ATMega32u4.
A while ago we had a post about a solar powered time lapse rig. Time lapse movies take a while, and the results are finally in.
Misumi is doing something pretty interesting with their huge catalog of aluminum extrusions, rods, bolts, and nuts. They’re putting up BOMs for 3D printers. If you’ve ever built a printer with instructions you’ve somehow found on the RepRap wiki, you know how much of a pain it is to go through McMaster or Misumi to find the right parts. Right now they have three builds, one with linear guides, one with a linear shaft, and one with V-wheels.
So you’re finally looking at those fancy SLA or powder printers. If you’re printing an objet d’arte like the Stanford bunny or the Utah teapot and don’t want to waste material, you’re obviously going to print a thin shell of material. That thin shell isn’t very strong, so how do you infill it? Spheres, of course. By importing an object into Meshmixer, you can build a 3D honeycomb inside a printed object. Just be sure to put a hole in the bottom to let the extra resin or powder out.
Remember that episode of The Simpsons where Homer invented an automatic hammer? It’s been reinvented using a custom aluminum linkage, a freaking huge battery, and a solenoid. Next up is the makeup shotgun, and a reclining toilet.
[Jan] built a digitally controlled analog synth. We’ve seen a few of his
FM synths VA synths built from an LPC-810 ARM chip before, but this is the first one that could reasonably be called an analog synth. He’s using a digital filter based on the Cypress PSoC-4.
The hip thing to do with 3D printers is low-poly Pokemon. I don’t know how it started, it’s just what the kids are doing these days. Those of us who were around for Gen 1 the first time it was released should notice a huge oversight by the entire 3D printing and Pokemon communities when it comes to low-poly Pokemon. I have corrected this oversight. I’ll work on a pure OpenSCAD model (thus ‘made completely out of programming code’) when I’m sufficiently bored.
*cough**bullshit* A camera that can see through walls *cough**bullshit* Seriously, what do you make of this?
A little while ago, we complained that there aren’t many projects using the Microview, a very cool Arduino and OLED thing that might be just too big for a ring. [Johannes] answered the call with a slot car track timer. He’s using an infrared distance sensor to count off lap times for his slot car track and a mini thermal printer to print out the times. Video right here.
Too many cables in your freshman college dorm room? Here’s the solution.
Our Internet travels frequently take us to strange auctions (we’re still looking for a US Mail truck, btw), but this one takes the cake. 24kt gold plates that were flown in space for five and a half years weighing 6,015.5 grams (212.191 oz). At the current price of $1277.06/oz, this auction should go for $270,980 USD. I’m 99% sure this was part of the Long Duration Exposure Facility, but I have no clue why this much gold was flown. Surely they could have done the same amount of science with only a hundred thousand dollars worth of gold, right?
So here’s this, but this isn’t your everyday, “put an Arduino in a vibrator” crowdfunding campaign. No, they actually have some great tutorials. Did you know that a stroke sensor looks like shag carpeting? [Scott] tells us, “I believe the founders are all graduate students getting PhDs in something or other, starting a sex toy company on the side.” More power to ’em.
Speaking of dildonics, the guy who coined that term will be giving one of the keynotes at the Vintage Computer Festival East this year. Yes, we’ll be there in full force.
Listening tests reveal significant sound quality differences between various digital music storage technologies. Finally the audiophile press is tackling the important questions. This listening test looks at the difference between two four-bay NAS boxes, with one making the piano on Scherzo and Trio from Penguin Café Orchestra’s Union Cafe sound more Steinway-like, while another NAS makes it sound more like a Bosendörfer. Yes, your choice of digital storage medium can change the timbre of a piano. Another gem: “Additionally, the two units also had different processor architectures, which might also affect perceived audible differences.” There must be a corollary to Poe’s Law when it comes to audiophiles…
[10p6] has begun a project that can play every old Atari cartridge. Right now it’s just a few bits of plastic that fits every non-Jaguar Atari cartridge, but it’s a start.
The Android IMSI-Catcher Detector. You’ve heard about Stingrays, devices used by law enforcement that are basically fake cell towers. These Stingrays downgrade or disable the encryption present in all cellphones, allowing anyone, with or without a warrant, to listen in on any cell phone conversation. Now there’s an effort to detect these Stingrays. It’s open source, and they’re looking for volunteers.
[Rob] sent in something that’s the perfect application of projection mapping. It’s called Face Hacking, and it’s pretty much just a motion capture systems, a few projectors, a whole lot of CG work, and just a tiny bit of dubstep. It look cool, but we’re wondering what the applications would be. Theatre or some sort of performance art is the best I can come up with.
A while ago, [4ndreas] saw a 3D printed industrial robot arm. He contacted the guy for the files, but nothing came of that. [4ndreas] did what anyone should do – made his own 3D printable industrial robot arm. The main motors are NEMA 17, and printing this will take a long time. Still, it looks really, really cool.
