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.

PCBs can be art – we’ve known this for a while, but we’re still constantly impressed with what people can do with layers of copper, fiberglass, soldermask, and silkscreen. [Sandy Noble] is taking this idea one step further. He took C64, Spectrum, and Sinclair PCBs and turned them into art. The results are incredible. These PCBs were reverse engineered, traced, and eventually turned into massive screen prints. They look awesome, and they’re available on Etsy.

$100k to bring down drones. That’s the tagline of the MITRE Challenge, although it’s really being sold as, “safe interdiction of small UAS that pose a safety or security threat in urban areas”. You can buy a slingshot for $20…

[styropyro] mas made a name for himself on Youtube for playing with very dangerous lasers and not burning his parent’s house down. Star Wars is out, and that means it’s time to build a handheld 7W laser. It’s powered by two 18650 cells, and is responsible for more than a few scorch marks on the walls of [styropyro]’s garage.

Everybody is trying to figure out how to put Ethernet and a USB hub on the Pi Zero. This means a lot of people will be launching crowdfunding campaigns for Pi Zero add-on boards that add Ethernet and USB. The first one we’ve seen is the Cube Infinity. Here’s the thing, though: they’re using through-hole parts for their board, which means this won’t connect directly to the D+ and D- USB signals on the Pi Zero. They do have a power/battery board that may be a little more useful, but I can’t figure out how they’re doing the USB.

[Keith O] found a fascinating video on YouTube and sent it into the tips line. It’s a machine that uses a water jet on pastries. These cakes start out frozen, and come out with puzzle piece and hexagon-shaped slices. Even the solution for moving cakes around is ingenious; it uses a circular platform that rotates and translates by two toothed belts. Who would have thought the latest advancements in cutting cakes and pies would be so fascinating?

It’s time to start a tradition. In the last links post of last year, we took a look at the number of views from North Korea in 2014. Fifty-four views, and we deeply appreciate all our readers in Best Korea. This year? For 2015, we’ve logged a total of thirty-six views from the Democratic People’s Republic of Korea. That’s a precipitous drop that deserves an investigation. Pyongyang meetup anyone?

If you don’t have a Raspberry Pi Zero right now, you’re not getting one for Christmas. Who would have thought a $5 Linux computer would have been popular, huh? If you’re looking for a new microcontroller platform you can actually buy, the Arduino / Genuino 101 is available in stores. This was released a few months ago, but it still looks pretty cool: DSP, BTLE, and a six-axis sensor.

If you don’t know [David], the Swede, you should. He’s the guy that launched a glider from a high altitude balloon and is one of the biggest advocates of tricopters. Now he bought an airplane wing for his front yard. It was an old Swedish air force transport aircraft being broken up for scrap. Simply awesome.

Chocolate chips. Now that the most obvious pun is out of the way, here’s how you make DIP8 cookie cutters.

[Barb] is over at the Crash Space hackerspace in LA, and she has a YouTube channel that goes over all her creations. This week, it’s a layered wood pendant constructed out of many layers of veneer. Take note of the 3M 77 spray glue used for the lamination and the super glue used as a clear, hard finish.

Star Wars was released and we have a few people digging through the repertoire to see what [John Williams] lifted for the new movie. Here’s musical Tesla coils playing the theme for the Force.

Flickr gives you a full gigabyte of storage, but only if you upload JPEGs, GIFs, and PNGs. That doesn’t prevent you from using Flickr as your own cloud storage.

We know two things about [Hans Fouche]: he lives in South Africa and he has a gigantic 3D printer. His latest creation is an acoustic guitar. It may not sound great, but that’s the quality of the recording. It may not play great, but he can fix that with some acetone vapor. It would be very interesting to see 3D printing used in a more traditional lutherie context; this printer could easily print molds and possibly even something to bend plywood tops.

Starting in 1990, [deater] would make a yearly Christmas-themed demo on his DOS box. You can really see the progression of technology starting with ANSI art trees written in BASIC, to an EGA graphical demo written with QBASIC to the last demo in 96 made with VGA, and SoundBlaster effects written in Turbo Pascal and asm.

So you’ve been rocking a tin foil hat for years now, and people have finally gotten used to your attire and claims that fluoridated water is a government mind control experiment. This holiday, how about something a little more stylish? Yes, it’s a Kickstarter for the World’s First Signal Proof Headwear. This fashionable beanie or cap protects you from harmful electromagnetic rays. Next time you shoot an eighteen minute long YouTube video of a wheezing rant about chemtrails, look fashionable with Shield – the world’s first stylish signal proof hat.

That last tip came to us from a Crowdfunding marketing agency. That means money was exchanged for the purposes of marketing a modern tin foil hat.

[Mike] has an old IBM 5155, the ‘luggable’ computer with design cues taken from the first Compaq. With an Ethernet adapter and a little inspiration, He was able to get this old computer to load the Hackaday retro edition.

[gyrovague] has a Chromecast that’s a bit janky. When it comes to electronics, strangeness means heat. The solution? A heat sink for the Chromecast. You don’t even need a proper heat sink for this one – just epoxy a big ‘ol transformer to the aluminum plate in the Chromecast.

This year, Keysight gave away a pile of test and measurement gear to the i3Detroit hackerspace. Keysight is doing it again, with a grand prize of around $60,000. Entries close on the 15th. Protip: you, personally, don’t want to win this for tax reasons. A non-profit does.

The Internet recently caught wind of a satellite modem being sold by Sparkfun. It’s $250 for the module, with a $12/month line rental, and each 340 byte message costs $0.18 to receive. Yes, it’s cool, and yes, it’s expensive. If you ever need to send a message from the north pole, there you go.

Need to remove the waterproof coating from LED strips? Don’t use a knife, use a Dremel and a wire brush.

[Camus] had it all wrong. After a few hundred years of rolling a stone up a mountain, Sisyphus would do what all humans would do: become engrossed in novelty. The stone would never reach the summit, but it could roll off some pretty sweet ramps. That mountain goat that ticked him off a few decades ago? If Sisyphus let go right now, the stone would probably take that goat out. Sisyphus, like all of us, would be consumed in meaningless novelty. One must imagine Sisyphus happy.

The pumpkin spice must flow. It’s the holidays and for a lot of us that means copious amounts of baked goods. How about an edible sandworm? It looks like something close to a cinnamon roll.

This December’s Marie Claire – whatever that is, I have no idea – features haute circuits. These circuit boards are the work of [Saar Drimer] and Boldport, makers of fine circuit board art. We’ve seen his work a number of times featuring squiggly traces and backlit panels. This seems to be the first time Boldport and the entire idea of PCB art has infiltrated the design world. He also does puzzles.

Raspberry Pi cases simply do not look cool. There’s ports coming out everywhere, and plastic really doesn’t look that great. You know what does look great? Walnut. [Karl] made a few of these out of walnut, MDF and solid aluminum. He’s thinking he might bring this to market, you can check out his webzone here.

Self-driving cars being sold right now! That’s an eBay link for a DARPA Grand Challenge vehicle, a heavily modified Isuzu VehiCross loaded up with computers, a laser scanner, camera, and connected to actuators for steering, brake, pedals, and shifter.

A few years ago, a snowboarding company realized they could use YouTube as a marketing device. They made some really cool projects, like a snowboard with battery-powered heaters embedded in the core of the board (yes, it works). There’s only so many different snowboards you can build, so they turned to surfboards. In fact, they turned to cardboard surfboards, and last week they made a cardboard electric guitar in the Fender custom shop. It’s a completely understandable linear progression from A to B to I don’t know what kind of glue they’re using.
