Hackaday Links: The Last One Of 2014

The guy behind the Microslice, a tiny Arduino-controlled laser cutter, has a new Kickstarter out. It’s called the Multibox PC, and it’s exactly what you need if you want to turn a Raspi, Banana Pi, HummingBoard, or Odroid U3 into an all-in-one desktop. 14″ 1366 x 768 LCD, and speakers turns dev boards into a respectable little Linux box.

If you’re learning to design schematics and lay out PCBs, you should really, really think about using KiCAD. It’s the future. However, Eagle is still popular and has many more tutorials. Here’s another. [Mushfiq] put together a series of tutorials for creating a library, designing a schematic, and doing the layout.

Another kickstarter wristwatch. But wait, this thing has a circular display. That’s really cool. It’s a 1.4″ 220×220 pixel, 262k color display. No, the display doesn’t use a polar coordinate system.

[Jari] wrote a digital logic simulator, Atanua, started selling licenses, and figured out it wasn’t worth developing on his own anymore. As promised, Atanua is now open source. If you want to look at the finances behind Atanua, here you go.

In 1970, you didn’t have a lot of options when it came to memory. One of the best options was Intel’s 1405 shift register – 512 bits of storage. Yes, shift registers as memory. [Ken Shirriff] got his hands on a memory board from a Datapoint 2200 terminal. Each of the display boards had 32 of these shift registers. Here’s what they look like on the inside

There’s a lot of talk about North Korean hackers, and a quick review of the yearly WordPress stats for Hackaday puts a tear in our eye. This year, there were fifty-four views from the Democratic People’s Republic of Korea. That’s just great. It’s awesome to see the hacker ethos make it to far-flung lands and through highly restricted firewalls. There’s still a long road ahead of us, though, and we’ll redouble our efforts on bringing the hacker mindset to Tuvalu and Saint Helena in the year 2015.

Christmas Lights And Ships In A Bottle

Thanksgiving was last week, and Christmas has been invading department stores for two or three months now, and that can only mean one thing: it’s time to kill a tree, set it up in your living room, and put a few hundred watts of lights on it. All those lights, though; it’s as if Christmas lights were specifically invented as fodder for standup comedians for two months out of the year. Why can’t someone invent wireless Christmas lights?

We don’t know if it’s been invented, but here’s a Kickstarter campaign that’s selling that same idea. It’s called Aura, and it’s exactly what it says on the tin: wireless Christmas lights, controllable with a smartphone. If it works, it’s a brilliant idea.

Phoenard, A Prototyping Gadget

The Hackaday Prize party wasn’t just about the five finalists; actually, there were more THP entries in attendance – All Yarns Are Beautiful, OpenExposer, M.A.R.S., a 3D scanner, and a few more that I’m forgetting – than actual finalists. In addition, a number of people brought projects that had never seen the light of day, like [Ralf] and [Pamungkas]’ Phoenard.

Phoenard is a Kickstarter project the guys launched at the prize party, something they could attend as a little side trip after manning the ‘maker’ part of the Atmel booth at Electronica. They’ve come up with a tiny handheld device that can only be described as a ‘gadget’. It has a touchscreen, a battery, an MegaAVR, a few connectors, and not much else. What makes this project cool is how they’re running their applications. A bootloader sits on the AVR, but all the applications – everything from a GSM phone to an MP3 player – lives on a microSD card.

The Phoenard guys have come up with a few expansion modules for Bluetooth LE, GSM, GPS, and all the usual cool modules. Plugging one of these modules into the back of the device adds capability, and if that isn’t enough, there’s an old 30-pin iPhone connector on the bottom ready to accept a prototyping board.

Video of these guys below.

Tesla Truck Wants to Bring The Makerspace To The Children

With so many budget cuts, many public schools find themselves having to cut “unnecessary” programs such as shop, art, and music classes. They simply can’t afford to keep those things running and also teach other important concepts like math, language, and history. The obvious side effect is that kids don’t have a safe place to be creative and learn to make things with their hands.

Luckily, the maker movement has been rapidly growing over the last few years with makerspaces popping up all over the globe. These places are picking up the slack left behind by the budget cuts that hurt our public schools. But while makerspaces are getting more and more common, they still don’t exist everywhere. Even in those places lucky enough to have a makerspace, not everyone is aware that they exist and not everyone can afford to be a full-time member. This is where Tesla Truck comes in.

The Tesla Truck’s mission statement is “to provide a cutting-edge, mobile, hands-on STEM lab, where students, teachers, and makers can teach, learn, collaborate, create, and innovate.” It’s a noble cause for sure, but how do they plan to do this? This group intends to outfit a truck with the kinds of tools every maker dreams of. These would include a 3D printer, laser cutter, CNC plasma cutter, mill and lathe, electronics bench, and more.

Obviously just having a bunch of high-end tools is not going to cut it. Someone is going to have to teach people how to properly use these tools. The group behind the Tesla Truck is made up of educators, engineers, and published researches who have been doing this kind of thing for a while now. This group has been packing up their own personal tools into their hatchbacks and setting up shop in school classrooms around New York City, only to have to break down at the end of the day and bring them all home again. Together with the students, this group has built things like robots, quadcopters, and water purifiers. The Tesla Truck will give them the ability to reach more people much more easily.

The Tesla Truck is looking to raise a total of $62,804.01 to make their dream a reality. They have raised more than half of that outside of crowd funding. They’ve now turned to Indiegogo to raise the last $24,300. They have ten days left and they are almost halfway to their goal. You can watch their campaign video below to get a better feel for what they are all about. Continue reading “Tesla Truck Wants to Bring The Makerspace To The Children”

Carvey, the CNC Machine for Everyone

Over the past few years, [Bart Dring] has contributed immensely to the homebrew CNC machine scene, with the creation of MakerSlide linear rail, the buildlog.net open source laser cutters and CNC machines, and a host of other builds that have brought the power of digital fabrication to garages and workshops the world over. After a year of work, he, along with Inventables, is releasing Carvey, the CNC machine for everyone else.

Carvey is heavily inspired by Inventables other CNC machine, the Shapeoko, but built to be the Makerbot to the Shapeoko’s RepRap, without all the baggage that goes along with that analogy, of course. The machine has a 300W spindle capable of cutting wood, plastic, foam, carbon fiber, and linoleum, as well as aluminum and brass. There are a few interesting features like a color-coded bit system, and this time the machine has an enclosure for containing MDF dust.

CiebwEA13yxYp576g_7HRNUx06KmzO3QEqGCLfs4kRoCAD programs might be a little too foreboding for someone just getting into the world of CNC, so Inventables has created their own design program called Easel. It’s a web app that allows you to design all your parts for the Carvey and send them all to the machine without worrying about speeds, feeds and all the other intimidating machinist terminology. You can, of course, output GCode from Easel, so those of us with slightly more complex toolchains can still use the Carvey.

Inventables is Kickstarting their production, with the non-early bird Carveys going for $2400. That’s a bit cheaper than some extremely similar machines we’ve seen on Kickstarter before.

Anonabox: How To Fail Horribly at Kickstarter

Late last week, Anonabox hit Kickstarter, glomming on to concerns over security, privacy, and censorship. The project was picked up on the usual tech blogs, lauding this project as the pinnacle of the Open Source, Open Hardware movement and a great investment for the privacy-minded technocrat in a post-Snowden world.

Then, the creator of Anonabox did an AMA on reddit. It was quickly discovered that the entire project was an off the shelf router found on AliExpress with reflashed firmware. The router sells for $20 in quantity one, and the Anonabox Kickstarter is giving them away with a minimum $51 pledge. The new firmware is basically a standard OpenWrt installation with a few changes to the config files. The project claims to solve the problem of hardware backdoors, but ships with a backdoor root password (the password is ‘developer!’), open WiFi, and ssh open by default. The Anonabox also claims to be a plug and play solution to security and privacy on the Internet, meaning if this project ever ships, there will be a lot of people who won’t change the default configuration. That’s rather hilarious in its implications.

According to the Kickstarter campaign, the Anonabox has gone through four years of development and four generations of hardware. [August] even has a great graphic demonstrating that each successive generation has reduced the size in half and doubled the system resources:

Anyone with the slightest eye for detail will quickly realize that components, like Ethernet jacks, SD cards, and CF cards are always the same size. I wonder what this graphic would look like if all the boards were scaled so they were in proportion to each other?

Image rescaled so all boards are proportional to each other

Oh. That’s not fishy at all.

As with most Kickstarters that have seen this much negative attention, the project was suspended just a few hours ago, but not before gathering more than $600,000 in pledges at its peak.

Although the Anonabox failed, there is a market for a Tor-enabled router, and luckily we have one on hackaday.io. It’s so great that some of the copy for the Kickstarter campaign was lifted directly from this project. With a wealth of market research available, we can only hope that [CaptainStouf] runs his own campaign for the UnJailPi.

Kickstarter Monitor Will Brighten Your Day

Keeping up with a kickstarter campaign can be quite a task, especially if your project is real (looking at you, Scribble Pen!) and you’re trying to keep up with product fabrication and all the other logistics involved in bringing a product to market. [macetech] are currently in the middle of a campaign themselves and built a loud, bright alert system to notify them of any new kickstarter backers.

The project uses a LED marquee to display the current number of backers, but every time a new backer contributes to the project, a blindingly bright green arrow traffic signal is illuminated and a piezo speaker plays a celebration tune. All of these devices are controlled by an Arduino Yun which, with its built-in Atheros chipset, easily connects to the network and monitors the kickstarter page for changes.

[macetech] used some interesting hardware to get everything to work together. They used a USB-to-RS232 cable with and FTDI chip to drive the LED marquee and a PowerSwitchTail 2 from Adafruit to drive the power-hungry traffic signal. Everything was put together in a presentable way for their workshop and works great! All of the source code is available on their project page, and you can check out their RGB LED Shades kickstarter campaign too.
