A Slew Of NYC Meetups With Tindie And Hackaday This Week

September 18, 2017 by Brian Benchoff 3 Comments

This is a busy, busy week for Tindie and Hackaday. We’re going to New York, and we have a ton of events planned.

First up is the monthly Hackaday meetup. This time, we’re teaming up with Kickstarter for a pre-Maker Faire Meetup. We’ll be hosting this at Kickstarter’s HQ, and already we have an impressive line of speakers set up to talk about Assistive Technology. These speakers include:

Anita Perr and R. Luke Dubois from the NYU Ability Project
Andrew Chepaitis from ELIA Life Technology

Also on deck for the for the Hackaday x Kickstarter meetup are live demos from WearWorks, who are developing the WAYBAND, a haptic navigation device and from Elia Frames, a tactile reading system.

The Hackaday x Kickstarter meetup will be Thursday, September 21st, starting at 6:30pm. Here’s the link to RSVP.

This weekend is also World Maker Faire New York and Tindie will be out in force showcasing all the wonderful bits and bobs developed by the Tindie community.

On deck will be [Jasmine] and [Brandon] from Tindie, and of course we’re inviting Tindie sellers to drop by the booth throughout the weekend and showcase their wares.

Also on deck for the World Maker Faire will be [Shulie], [Shayna] and myself. We’ll be tossing brand new Tindie stickers into the audience and giving out Tindie Blinky Badges. If you’ve ever wanted to show your enthusiasm for DIY hardware, now you can with an electronic blinky lapel pin. Solder it up and listen to Benchoff rationalize why it doesn’t need a current limiting resistor! Such fun!

Need For New Hobby Leads To Stone Marbles

May 18, 2017 by Mike Szczys 14 Comments

[Tom Lange] said he was looking for a new hobby when he saw a marble made out of stone and wondered what goes into making one for himself. Fast forward three years and he set up shop at the Madison Mini Maker Faire to show off the tools he built and the fascinating glossy orbs he’s produced. Read on to see the awesome process he uses to turn a hunk of stone into a perfect marble.

Hackaday Links: March 19, 2017

This is from the Daily Fail, but a working Apple I is going up on the auction block. It’s expected to bring in $317,693 USD. In other news, we’re going to be at the Vintage Computer Festival East at the end of the month. There is usually an Apple I there.

The most popular crowdfunding campaign of the month is Lego tape. It’s an adhesive-backed tape with studs on the top, allowing you to clip Lego pieces into place. How easy would this be to create at home? It’s really just a silicon mold and some 3M stickytape. Anyone up for a home casting challenge?

You guys know the Hackaday Overlords have a Design Lab, right? What’s a Design Lab? It’s a place filled with tools where we allow residents to come in for free, build stuff, give them training, and let them keep all their IP. It’s like a hardware accelerator, but focused on Open Source hardware. It is our gift to the community and we ask nothing in return. But that’s not important right now. We’re doing shots.

2017 will be the first year Maker Faire will have three flagship faires. New York is a given, as is the Bay Area. and A few weeks ago, Chicago grabbed the third flagship faire. If you’ve already bought tickets and scheduled your trip, terrible news: the Chicago Maker Faire has been postponed until late fall.

Flip clocks are cool. What’s a flip clock? The clock in Groundhog Day, or a bunch of flaps, gears, and a synchronous motor that displays the time. You know what’s not cool about flip clocks? They’re usually stuffed in horrible 70s plastic enclosures painted Harvest Gold or Avacado. [bentanme] found a flip clock and stuffed it in a glass jar. It’s kept in place by a few 3D printed parts that ingeniously keep the clock from moving around while still allowing you to see the gears. Neat.

Ottawa Maker Faire: Droids And Pick And Place Machines

October 22, 2016 by Steven Dufresne 4 Comments

Three things that I love about participating in Maker Faires are seeing all the awesome stuff people have done over the past year, spending time with all my maker friends in one big room over two days and the reactions to what I made. The 2016 Ottawa Maker Faire had all this in spades.

BB-8 – Droid With Magnetic Personality

My BB-8 droid

There’s just something about BB-8 that touches people. I once heard of a study that showed that when buying kid’s toys, adults were attracted to circles, that that’s the reason teddy bears often have round heads with big round eyes. Similar reactions seem to happen with BB-8, the droid from last year’s Star Wars movie. Adults and kids alike pet him, talk baby-talk to him, and call to him with delight in their voice. I got those reactions all throughout the Maker Faire.

But my favorite reaction happened every time I removed the head and lifted the top hemisphere of the ball to expose the electronics inside. Without fail the reaction of adults was one of surprise. I don’t know if it was because of the complexity of the mechanism that was revealed or because it was just more than they expected. To those whom I thought would understand, I gave the same speech:

“This is the remote control receiver taken from a toy truck, which puts out negative and positive voltages for the different directions. That goes to this ugly hack of a board I came up with that converts it all to positive voltages for the Arduino. The Arduino then does pulse width modulation to these H-bridge driver boards, for speed control, which then talk to these two drill motors.”

Those I wasn’t sure would understand were given a simpler overview. Mine’s a hamster drive (we previously covered all the possible ways to drive a BB-8) and so I showed how it sits on two Rollerblade wheels inside the ball. I then flipped it over to show the heavy drill batteries underneath, and then explained how the magnets at the top of the drive mechanism attracted the magnets under the head, which got another look of revelation. All went away satisfied.

But BB-8 sometimes needs a break from human interaction and seeks out its own kind, like Bowie which you can read about below along with more awesome Maker Faire exhibits.

Tiny Smoothies At Maker Faire

October 5, 2016 by Brian Benchoff 43 Comments

For almost the last decade, desktop 3D printing has, at its heart, been centered around 8-bit microcontrollers. The ATmegas and other Atmel chips are good enough to move a few steppers and squirt some plastic. With faster processors, you get smoother acceleration, leading to better prints. Modern ARM devices have a lot of peripherals, allowing for onboard WiFi and Ethernet connectivity. The future is 32-bit print controllers.

Right now there are a few 32-bit controllers, from the very weird, out-of-nowhere controller for the Monoprice Mini 3D printer to the more traditional SmoothieBoard. Only one of these boards has the open hardware cred for a proper 3D printer controller, and a this year’s Maker Faire, Cohesion3D introduced a few machine control boards built on top of Smoothie that add a few interesting features and techniques.

The Tiny 3D Printers Of Maker Faire

October 2, 2016 by Brian Benchoff 16 Comments

Building a big 3D printer has its own challenges. The strength of materials does not scale linearly, of course, and long axes have a tendency to wobble. That said, building a bigbot isn’t hard – stepper motors and aluminum extrusion are made for industry, and you can always get a larger beam or a more powerful motor. [James] is going in the opposite direction. He’s building tiny, half-scale printers. They’re small, they’re adorable, and they have design challenges all their own.

At this year’s New York Maker Faire, [James] is showing off his continuing project of building baby 3D printers. He has a half-scale wooden Printrbot, a half-ish scale Mendel Max, a tiny Makerbot Replicator, and a baby delta and baby Ultimaker in the works.

Click past the break for a gallery, and more info on [James’s] tiny creations.

Arduino Vs. Arduino: Arduino Won

October 1, 2016 by Brian Benchoff 89 Comments

For the last two years, Arduino LLC (the arduino.cc, Massimo one) and Arduino SRL (the arduino.org, Musto one) have been locked in battle over the ownership of the Arduino trademark. That fight is finally over. Announced at the New York Maker Faire today, “Arduino” will now go to Arduino Holding, the single point of distribution for new products, and a non-profit Arduino Foundation, responsible for the community and Arduino IDE.

Since early 2015, Arduino — not the Arduino community, but the organization known as Arduino — has been split in half. Arduino LLC sued Arduino SRL for trademark infringement. The case began when Arduino SRL, formerly Smart Projects SRL and manufacturers of the Arduino boards with a tiny map of Italy on the silk screen, began selling under the Arduino name. Arduino LLC, on the other hand, wanted to internationalize the brand and license production to other manufacturers.

While Arduino and Arduino have been tied up in court for the last few years, from the outside this has look like nothing else but petty bickering. Arduino SRL forked the Arduino IDE and bumped up the version number. Later, an update from SRL was pushed out to Amazon buyers telling them Arduino.org was the real Arduino. Resellers were in a tizzy, and for a time Maker Faires had two gigantic Arduino booths. No one knew what was going on.

All of this is now behind us. The open source hardware community’s greatest source of drama is now over.

I spoke with Massimo after the announcement, and although the groundwork is laid out, the specifics aren’t ready to be disclosed yet. There’s still a lot to work out, like what to do with the Arduino.org Github repo, which TLD will be used (we’re rooting for .org), support for the multitude of slightly different products released from both camps over the years, and finer points that aren’t publicly visible. In a few months, probably before the end of the year, we’ll get all the answers to this. Now, though, the Arduino wars are over. Arduino is dead, long live Arduino.
