Hackaday Links: Valentine’s Day, 2016

A few months ago, we posted all the videos from the 2015 Hackaday SuperConference. Putting all of these videos up on YouTube isn’t the greatest idea, and thanks to [Jason Scott] of the Internet Archive and a little bit of sneakernetting, all the talks are also available on archive.org.

As an aside, the SuperCon was filmed on two Blackmagic URSA cameras. The resulting files for the talks on both cameras came in at a little over one Terabyte. These were edited down into the finished videos for YouTube, at around 20 Gigs per video. Once those hit the YouTube servers, they were converted once again (trust me, this made the most sense), and I was able to download the YouTube files and sneakernet all the talks to [Jason] on an 8GB thumb drive. The next time we do this, we’ll build a Xeon-based SLI Titan rig for video editing.

The German TV show NEO MAGAZIN Royale asked their viewers to send in old hardware. These old floppy drives, scanners, typewriters, hard drives, modems, and speakers would be turned into instruments. The German hip hop group, Fettes Brot performed Die da on these instruments with sufficiently electronic results.

You know we’re having a con in Belgrade on April 9, right? Wait, I’m sorry. 9 April. The call for proposals ends very, very soon. If you have something cool to talk about, fill out the form.

Montreal has a lot of great architecture, all of which is coincidently held together by Robertson screws. Now one of those famous old buildings, the Saint-Sulpice Library is turning into a hackerspace or tech incubator sort of thing thanks to a $17 Million Canadian Peso investment from the city and province.

Just a reminder that the NL6621 WiFi SoC exists. It’s been called the ESP8266 killer, but some of the most recent posts on the English language development forum are for buying phentermine – an appetite suppressant – without a prescription. The people demand information, so if you have some, put it in the comments below.

For a very long time, the original, 11 foot-long on-screen model of the USS Enterprise from Star Trek the original series – “NCC one seven O one. No bloody A, B, C, or D.” – was housed in the Smithsonian’s Air and Space Museum in Washington, DC. Recent visitors may have noticed the Enterprise is no longer on display. It’s being restored by the finest aircraft conservators in the world. There are a few great videos showing off how much goes into restoring a cultural icon.

Last weekend Hackaday visited Sparklecon in Fullerton, CA. This means I was in LA on the last Saturday of the month. What’s so special about that? The W6TRW Swap Meet at Northrop Grumman in Redondo Beach. Here’s the pics from that. The best thing I found? A wooden acoustic coupler modem for $15. Once I told the guys at the booth what it was, the price went up to $20. Still worth it.

What’s the worst thing about modern computers? They’re all LCDs, and that means worse resolution, terrible colorspace, and monitors that are very, veeeerrrrryyyy wide. The consequence of this is a complete and total lack of screen savers. Never fear, because the flying toaster is back, this time as an SD card holder. It’s 3D printable, so if you have some white, silver, and black filament sitting around, you know what to do.

The USB Killer hit the tips line a few times this week for inexplicable reasons. We’ve seen it before, but we haven’t seen it again. Surprisingly, no one – outside a bizarre Indiegogo campaign that shouldn’t exist – has made their own USB killer. Here’s your call to action: build a USB killer, and I’ll test it out.

An SDIP-64 chip compared to a DIP-28 chip. Note the finer lead spacing on the SDIP device.

There’s more variety to your standard DIP-packaged chips than you might expect. The weirdest of these – at least when it comes to perfboard construction – is the SDIP, or Skinny Dual In-line Package. Instead of having a standard 0.1″ pitch between leads, the SDIP has a 0.070″ pitch. [Chuck] was having some problems looking for SDIP to DIP adapters until he found this amazing trick the connector companies don’t want you to know aboutJust plop the chip in at a 45º angle, bend a few pins, and you’re good to go.

[Damien] has been working on MicroPython for a while now. We did an interview with him a while ago about porting Python to tiny microcontrollers, and soon the BBC micro:bit will be getting Python into the hands of millions of British schoolchildren. Now [Damien] has a Kickstarter to get MicroPython to the bare metal of an ESP8266. That would be extremely interesting; there’s a lot you can do with an easily scriptable Internet Thing running Python.

A little over a month ago, [Renier] won the Hackaday Prize Best Product competition with the Vinduino, a device that cuts water usage of vinyards (and orchards, I guess) by 25%. Now he’s won the IoT awards for Best DIY Project.

We have lost a great inventor. [Artur Fischer], inventor of the plastic drywall plug, fischertechnik, the plastic wall plug, photo flash light, and holder of over 1100 patents (more than the great Edison), passed away this week.

Who remembers Glider? That old Macintosh game where you fly a paper airplane around a house is now available on GitHub. The creator of Glider, [John Calhoun] put all the code up a few days ago. If you have Metrowerks Code Warrior sitting around on an old box, feel free to dig around.

 In the ‘this guy totally won’t get sued’ column is MagSafe for iPhones. The MagSafe power adapter is Apple’s largest contribution to humanity, but they are a little protective about it.

We have two calls for the community: [jimie] had a go at programming the latest, coolest, open source radio. Programming it is hard. Has anyone found an improved guide? Second, I now have a Tadpole Computer that was former property of Quallcom. I can’t find any info on getting *nix or *BSD on it. Anyone have any experience?

The RepRap wiki was spammed this week. Everything is fine now, but I feel I should call attention to the fact that the RepRap wiki needs some people to contribute, organize, and maintain everything. The wikis for obscure anime shows are better than the RepRap wiki, so if you’re looking to contribute to an important open source project, there ‘ya go.

The 200cc, 5.5HP, 4-stroke OHV Honda GX200 engine is found in a whole lot of tools, and is a fantastic power plant to build a go-kart around. It also costs about $350. There are clones of this engine available direct from China for about $100. Here’s how you add a turbo to one of these clone engines.

Freescale makes some pretty cool sensors and [Juan Ignacio Cerrudo] figured they needed breakout boards. He has some boards for a low-power three-axis accelerometer, an accelerometer and magnetometer, and a pressure sensor.

The Tektronix TDS744A is an older but still extremely capable 500MHz, 2Gsps, 4-channel scope. You can upgrade it to the 1GHz TDS784A by desoldering a few resistors. Very cool if you’re looking for a cheap-ish 1GHz scope.

[TheBackyardScientist] hung out with some cub scouts a few weekends ago and launched a high altitude balloon over Florida. The payload included a game camera, APRS tracker, GoPro, and a few other bits and bobs. The balloon reached 106,000 feet and landed only a few miles from Cape Canaveral.

Big RC planes – UAVs especially – are a pain to launch. Flying wings above a certain size are just dangerous to launch by hand, and landing gear is heavy and for the most part unnecessary. What’s the next best solution? A trebuchet, of course. It mounts on a car and is able to give a UAV a little bit of altitude and some speed. A pretty good idea that could be easily implemented with some load-bearing PVC pipe.

Everybody likes the Game of Life, so here’s one built with a 6502. It’s built around a Western Design Center 65c816 board we’ve seen before, nine MAX7219 LED controllers mapped to the VIA, and nine 8×8 LED matrix displays. Here’s a video of it in action.

About a month ago, a search of AliExpress turned up Apple’s A8 CPU. I bought one. Here’s what I got. It’s a stupidly small pitch BGA, and I don’t have a datasheet. What am I going to do with it? Make a non-functioning board with a few ports, resistors, no traces, and the A8 chip planted square in the middle.

The BBC has commissioned a new series of Robot Wars. This is not Battlebots; that show was revived last year, and a second season will air again this summer. Robot Wars is the one with the ‘house’ robots. We would like to take this opportunity to remind the BBC that Robot Wars is neither Scrapheap Challenge nor Junkyard Wars, and by virtue of that fact alone is an inferior show.

[Fran] is a favorite around these parts. She’s taken apart a Saturn V Launch Vehicle Digital Computer, visited the Smithsonian Air and Space Museum warehouse, and is the occasional host of the Dinosaur Den with [Bil Herd]. Now, she’s relaunching her line of guitar pedals. ‘Boutique’ pedals are a weird market, but with the help of a few manufacturers, [Fran] is bringing her Peachfuzz pedal back to life through Kickstarter.

Want to be an astronaut? Here’s the application.

Here’s your monthly, ‘WTF is this thing on eBay’ link. It’s a clamshell/toilet seat iBook (c.2000), loaded up with an Intel i5 Broadwell CPU, 128 GB of Flash storage, 4 GB of RAM, a 12″ 1024×768 LCD, Gigabit Ethernet, WiFi, Bluetooth, and runs OS X El Capitan. I might be mistaken, but it looks like someone took the motherboard out of a 2015 MacBook Air, crammed it into a sixteen year old computer, and put it up on eBay. I’m not saying that’s what it is; this is from China, and there are people over there making new improved motherboards for a Thinkpad x61. Weirder stuff has already happened.

In the last installment of the Travelling Hacker Box, I asked if anyone can receive mail in Antarctica. A person with friends in the British survey team emailed me, but nothing came of that. It’s summer, so if Antarctica is going to happen, it needs to happen soon.

Everybody loves cheap stuff, and we hate telling everyone about coupon codes. That said, TI has a new LaunchPad development board they’re promoting. It’s based on the MSP432, the ARM extension of their MSP430 line. The MSP432 is an ARM Cortex M4F, low power, and planned for production later this year.

Here’s your daily CES garbage post. Through a collaboration between Sony and Nissan, a car has become a video game controller controller. A controller plugs into the ODB II port, reads throttle, brake, and steering wheel positions (and buttons on the dash/steering wheel, I guess), and translates that into controller input for a PlayStation 4. What games do they play with a car? You would think Gran Turismo, Rocket League, or other games with cars in them. Nope. Football.

Dangerous Prototypes is a legal Chinese company! [Ian] didn’t say anything about the process about becoming a legal Chinese company because he wrote a blog post, not a book. Shenzhen Dangerous Prototypes Electronics Technology Limited allows them to have an office in the Shenzhen electronics market, hire local and foreign hackers, host Hacker Camp Shenzhen, and allow people to apply for ‘Authorized Authority’ visa letters for the people who need them. Great news for a great company.

The Forge hackerspace in Greensboro, NC is growing. In just over a year they have 160 members and they’ve already outgrown their 3,400 square foot space. Now they’re moving to a larger space that’s twice the size and they’re looking for donations.

People have been taking old iPad screens and turning them into HDMI displays for years now. [Dave] got his mitts on a panel from a Macbook Pro 17″, and turned it into a monitor. It required a $50 LVDS adapter, but the end result is great – a 1920×1200 panel that looks pretty good.

Cx5 is a strange material that’s a favorite of model makers and prop replicators. It’s kind of like a wax, kind of like a clay, and a little bit like a plastic. Now it’s a 3D printer filament. It looks very interesting for sculpted and highly detailed models, something the 3D printing scene hasn’t had yet.

So you want a CNC machine, right? Tormach makes a good one, and here’s what it takes to put a PCNC440 in your garage. This is an incredible amount of work and a great excuse to buy an engine hoist.

[Zemnmez] could find dozens of apps and webpages that would calculate resistor color codes for him automatically. What he couldn’t find is one that would do it in reverse – i.e. type in a resistor value and return the correct color code. He made this.

[aggaz] needed a way to connect multiple MIDI devices to his computer. The MIDI spec provides a neat piece of hardware for just this occasion – the MIDI thru box. The only thing you need to build a single MIDI thru box is an opto-isolator and a buffer. It’s easy enough to build, although the DIN5 jacks used for MIDI devices are pretty expensive nowadays. (FWIW- We get an invalid certificate error when loading this page but you should still be able to load it.)

AliExpress always has some interesting stuff on it, and [Ethan] found something very cool. They’re A8 CPUs found in the latest iPhone. Are they real? Who knows. I bought one, and you’re going to get pictures in another links post in a month or so.

The Game Boy Micro was released by Nintendo in 2005 and quickly became one of the coolest and most desired handheld consoles on the planet. You need only look at the eBay listings for the Micro as evidence of its desirability. [ModPurist] took an old DS Lite and converted it into a Game Boy Micro – same idea, larger package.
