Yule-Inspired Tool Time With [Becky Stern]

And now for something completely different: [Becky Stern]’s musical tour of her favorite tools around the Adafruit factory is the best holiday tune we’ve heard since The Waitresses’ “Christmas Wrapping”. Of course, good tools are near and dear to us as well, and we found ourselves nodding frequently in agreement and smiling as broadly as [Billie, Ruby, and Gus], the anthropomorphic LED backup singers.

In other Adafruity news, it looks like their new Samsung SM482 pick and place machine was given the gift of eyes as big as pizza pies. What tools would you like to see under the tree, leaning against the Festivus pole, or all wrapped up a safe distance from the menorah this year? Do tell.

Logic Simulator Atanua Goes Free, Possibly Open Source

The history of software is littered with developers that built a great product, gave people a reasonable option to license the software, and ended up making a pittance. There’s a reason you don’t see shareware these days – nobody pays. It looks like [Gates] had a point with his Open Letter to Hobbyists.

Such is the case with Atanua. [Jari] built a nice little graphical logic simulator that has tens of thousands of downloads, and is being used in dozens of universities. [Jari] has sold only about 60 licenses for Atanua, netting him only a few thousand Euro. You can’t develop software with a pittance, so now [Jari] is giving Atanua away. This neat little logic simulator has reached the end of its life, the license is free, and [Jari] is out of the business.

This isn’t an ideal situation, but [Jari] is strongly considering open-sourcing Atanua. The code is a little bit of a mess at the moment, and cleaning it up will require a bit of work. [Jari] is leaving the option to buy a license for Atanua open, and anyone who wants to see this bit of software open sourced could buy a license or hundred.

While this isn’t great news for [Jari], if you’re looking for a neat tool to learn digital logic, you now have a very nice free option. Atanua simulates individual logic gates, 74-series chips, and even an 8051 microcontroller in real-time (up to about 1 kHz), with enough buttons, LEDs, and displays to do some very cool stuff. It’s more than enough to learn digital logic on, and good enough for a test bed for some odd and bizarre projects you might have floating around your head.

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”

Bluetooth Thingies at Maker Faire

In case you haven’t noticed, one of the more popular themes for new dev boards is Bluetooth. Slap a Bluetooth 4.0 module on a board, and you really have something: just about every phone out there has it, and the Low Energy label is great for battery-powered Internets of Things.

Most of these boards fall a little short. It’s one thing to throw a Bluetooth module on a board, but building the software to interact with this board is another matter entirely. Revealing Hour Creations is bucking that trend with their Tah board. Basically, it’s your standard Arduino compatible board with a btle module. What they’ve done is add the software for iOS and Android that makes building stuff easy.

Putting Bluetooth on a single board is one thing, but how about putting Bluetooth on everything. SAM Labs showed off their system of things at Maker Faire with LEDs, buttons, fans, motors, sensors, and just about every electrical component you can imagine.

All of these little boards come with a Bluetooth module and a battery. The software for the system is a graphical interface that allows you to draw virtual wires between everything. Connect a button to a LED in the software, and the LED will light up when the button is pressed. Move your mouse around the computer, and the button will turn on a motor when it’s pressed.

There are a few APIs that also come packaged into the programming environment – at the booth, you could open a fridge (filled with cool drinks that didn’t cost five dollars, a surprise for the faire) and it would post a tweet.

The Hackaday Store Lives Again!

Once upon a time there was a store where you could find the most amazing Hackaday shirts and other swag. If you managed to get one of the rare Jolly Wrencher adorned shirts back then, it’s probably about worn out by now. Prepare to rejoice, Hackaday has a completely new store packed with T-shirts, tools, and stuff to help you fill up those waking hours with hardware hacking goodness.

We’ve had a little fun over the last couple of days with posts that hint (maybe a bit too subtly?) that this was coming. We always try to have a little bit of fun for those of you who are really paying attention. Now we’re wondering who will be the first to implement the one-time pad as a dedicated piece of hardware… project ideas need to come from somewhere, right?

Take a look around the general store and you’ll see this time we have more than just stuff you wear. Hackers need tools and we’ve selected a small but inspiring group of must-have’s. The kits and toys we’ve selected are surely a rabbit hole of personal challenges and evolving hacks for you. And the best part is that these choices are one more way for us to promote the virtue of Open Design (it is the way). The only question now is what other open hardware do you want to see added to those ranks?

Cloning Tektronix Application Modules

Tektronix’s MSO2000 line of oscilloscopes are great tools, and with the addition of a few ‘application modules’, can do some pretty interesting tasks: decoding serial protocols, embedded protocols like I2C and SPI, and automotive protocols like CAN and LIN. While testing out his MSO2012B, [jm] really liked the (limited time) demo of the I2C decoder, but figured it wasn’t worth the $500 price the application module sells for. No matter, because it’s just some data on a cheap 24c08 EEPROM, and with a little bit of PCB design <<removed because of DMCA takedown>>

The application module Tektronix are selling is simply just a small EEPROM loaded up with an <<removed because of DMCA takedown>>. By writing this value to a $0.25 EEPROM, [jm] can enable two applications. The only problem was getting his scope to read the EEPROM: a problem easily solved with a custom board.

The board [jm] designed <<removed because of DMCA takedown>>, with the only additional components needed being an EEPROM, a set of contacts for reading a SIM card, and a little bit of plastic glued onto the back of the board for proper spacing.

Hackaday Links: May 4, 2014

We’ve seen a few builds from the Flite Test guys before, like a literal flying toaster, airsoft guns mounted to planes, and giving an electric plane an afterburner (that actually produced a little extra thrust). Now the Flite Test crew is gearing up for the Flite Fest, an all things remote-controlled flight convention in Malvern, Ohio during the last weekend in July. Seems like a pretty cool way to spend spend a weekend.

Unless you get one of those fancy resistor kits where every value has its own compartment in a case or plastic baggie, you’ll soon rue the day your loose resistors become disorganized. [Kirll] has an interesting solution to hundreds of loose resistors: packaging tape. If you want a resistor, just grab a pair of scissors.

Okay, these Adafruit “totally not Muppets™” are awesome. The latest video in the Circuit Playground series is titled, “C is for Capacitor“. There’s also “B is for Battery“, because when life gives you lemons, light up an LED. Here’s the coloring book.

A few years ago, a couple of people at the LA Hackerspace Crashspace put together an animated flipbook device – something between a zoetrope and the numbers in those old electromechanical clocks – and launched a kickstarter. Now they’re putting on a show, presented by Giant Robot, featuring the animated art of dozens of artists.

Vintage electronics? Yes. Vintage Soviet electronics? Here’s 140 pages of pictures, mostly of old measurement devices.
