We’re Headed to Maker Faire, Will You Be There?

The Hackaday Crew will be descending on San Mateo next weekend for Bay Area Maker Faire. Will you be there? Gerrit and I will be looking in every booth and byway for amazing hacks, new hardware, and anything else that tickles the fancy of hackers everyone.

We certainly didn’t miss the massive tin spider seen above at last year’s event. But it’s a huge venue, and I’m always afraid we’re going to miss something epic. If you’re exhibiting and want us to stop by, leave a comment below. If you know of something awesome that we shouldn’t miss this year, we’d love to hear about that too.

I’d also like to invite you to hang out with Hackaday on Saturday night. When the Faire closes its gates, something amazing happens every year at O’Neil’s Irish Pub. Don’t miss it!

Need a Ticket?

Texas Instruments sent us 4 Friday passes, and 9 weekend passes which we want to give away. The fairest way of doing that is a drawing using Twitter.

To enter, simply Tweet something about your favorite 2016 Hackaday Prize entry, including @Hackaday @TXinstruments #FairePass in the message. Here’s what an example Tweet looks like (don’t worry, I’m not eligible to win).

On Sunday, 4pm PDT we’ll make a list of all the Twitter handles that sent out a Tweet, then use random.org to choose 6 random numbers from that list. The second giveaway will happen at 4pm PDT on Wednesday 5/18, using the same procedure to choose the remaining 7 winners.

All of the obvious contest stuff applies: employees and family of Hackaday, Supplyframe, and TI are not eligible. Results of the drawing are final. We can’t substitute other prizes (we’re just giving away extra tickets) and this giveaway has no bearing on any other contests or winner selection.

Finally, an Upgrade for the TI-86

The eternal and everlasting TI-86 graphing calculator is a great calculator: first made back in 1997, and still used by students today. But its battery life kinda sucks. So [Dalius] decided to bring his TI-86 into the 21st century.

If you’re not familiar, the TI-86 runs off of 4 AAA batteries, preferably alkaline. If you use rechargeable NiMH they don’t last very long since they have a lower voltage per cell, which means it ends up draining even faster to a voltage level the TI-86 cannot operate at.

Hackaday Links: November 8, 2015

[Burt Rutan] is someone who needs no introduction. Apparently, he likes the look of the Icon A5 and is working on his own version.

Earlier this week, the US Air Force lost a few satellites a minute after launch from Barking Sands in Hawaii. This was the first launch of the three stage, solid fueled SPARK rocket, although earlier versions were used to launch nuclear warheads into space. There are some great Army videos for these nuclear explosions in space, by the way.

[Alexandre] is working on an Arduino compatible board that has an integrated GSM module and WiFi chip. It’s called the Red Dragon, and that means he needs some really good board art. The finished product looks good in Eagle, and something we can’t wait to see back from the board house.

The Chippocolypse! Or however you spell it! TI is declaring a lot of chips EOL, and although this includes a lot of op-amps and other analog ephemera (PDF), the hi-fi community is reeling and a lot of people are stocking up on their favorite amplifiers.

[Jeremy] got tired of plugging jumper wires into a breadboard when programming his ATMega8 (including the ‘168 and ‘328) microcontrollers. The solution? A breadboard backpack that fits right over the IC. All the files are available, and the PCB can be found on Upverter.

In case you haven’t heard, we’re having a Super Conference in San Francisco later this week. Adafruit was kind enough to plug our plug for the con on Ask an Engineer last week.

Mergers and Acquisitions: TI Looks to Snatch Up Maxim

BloombergBusiness is reporting rumors that Texas Instruments is in talks to acquire Maxim Integrated. Both companies have declined to respond to this leaked information. Earlier this year there were rumors that the two companies had been in talks in 2014 that didn’t result with an agreement.

We find it interesting that the article mentions Maxim doesn’t need to scale — yet we often find Maxim parts in short supply. If TI were to acquire the company this could change for some Maxium parts. Still, this move looks a lot like TI trying to bolster its hold on the portions of the analog chip market which both companies currently occupy.

Already this year we’ve seen Dialog acquire Atmel, Avago acquire Broadcom, and the merger agreement between Freescale and NXP. We probably missed a few, and this has us wonder who is next. Let us know what you think in the comments below.

New Part Day: The BeagleBoard Gets Bigger

Officially, the latest hardware revision we’ve seen from BeagleBoard is the BeagleBone Black, a small board that’s perfect for when you want to interface hardware to a Linux software environment. This last summer, the BeagleBone Green was introduced, and while it’s a newer hardware release, it’s really just a cost-reduced version of the BB Black. Over the entire BeagleBoard family, it’s time for an upgrade.

It’s been talked about for more than a year now, but the latest and greatest from the BeagleBoard crew is out. It’s called the BeagleBoard X15, and not only is it an extremely powerful Linux board, it also has more ports than you would ever need.

The new BeagleBoard features a dual-core ARM Cortex A15 running at 1.5GHz. There is 2GB of DDR3L RAM on board, and 4GB of EMMC Flash. Outputs include three USB 3.0 hosts, two Gigabit Ethernet controllers, one eSATA connector, LCD output, two PCIe connectors, and an HDMI connector capable of outputting 1920×1080 at 60 FPS. The entire board is open hardware, with documentation for nearly every device on the board available now. The one exception is the PowerVR SGX544 GPU which has a closed driver, but the FSF has proposed a project to create an open driver for this graphics engine so that could change in the future.

The expected price of the BeagleBoard X15 varies from source to source, but all the numbers fall somewhere in the range of $200 to $240 USD, with more recent estimates falling toward the high end. This board is not meant to be a replacement for the much more popular BeagleBone. While the development and relationship between the ~Board and ~Bone are very much related, the BeagleBone has always and will always be a barebone Linux board, albeit with a few interesting features. The BeagleBoard, on the other hand, includes the kitchen sink. While the BeagleBoard X15 hardware is complete, so far there are less than one hundred boards on the planet. These are going directly to the people responsible for making everything work, afterwards orders from Digikey and Mouser will be filled. General availability should be around November, and certainly by Christmas.

While it’s pricier than the BeagleBone, the Raspberry Pi, or dozens of other ARM Linux boards out there, The BeagleBone has a lot of horsepower and plenty of I/Os. It’s an impressive piece of hardware that out-competes just about everything else available. We can’t wait to see it in the wild, but more importantly we can’t wait to see what people can do with it.

Hacklet 70 – Calculator Projects

Hackers, makers, and engineers have long had a love affair with number crunching. Specifically with the machines that make crunching numbers easier. Today it may be computers, smart watches, and smartphones, but that wasn’t always the case. In the 50’s and 60’s, Slide rules were the rage. Engineers would carry them around in leather belt pouches. By the early 70’s though, the pocket calculator revolution had begun. Calculators have been close at hand for hackers and engineers ever since. This week’s Hacklet celebrates some of the best calculator projects on Hackaday.io!

calc1We start with [Joey Shepard] and RPN Scientific Calculator. No equals sign needed here; [Joey] designed this calculator to work with Reverse Polish notation, just like many of HP’s early machines. Stacks are pretty important for RPN calculators, and this one has plenty of space with dual 200 layer stacks. The two main processors are MSP430s from Texas Instruments. The user interface are a 4 line x 20 character LCD and 42 hand wired buttons. The two processors are pretty ingenious. They communicate over a UART. One processor handles the keyboard and display, while the other concentrates on crunching the numbers and storing data in an SRAM. The case for this calculator is made from soldered up copper clad board. It’s mechanically strong especially since [Joey] added a bead of solder along each joint. If you want to learn more about this technique check out this guide on FR4 enclosures.

[Joey] definitely improved his solder skills with this project. Every wire and connection, including the full SRAM address and data bus were wired by hand on proto boards. We especially like the sweet looking laser cut keyboard on this project!
