Although these meetups are highly informal (and bringing some of the cool stuff you’ve built is encouraged), we do have a few speakers lined up. Holly Cohen and John Schimmel of DIYAbility are speaking about using homebrew devices for making everyone’s life easier. Johnny Falla of the Enable Community Foundation will give a talk about using 3D printing technology to make hyper-affordable prosthetic devices for underserved populations. Chad Leaman will be representing the Neil Squire Society and will speak about using technology to empower people with disabilities.
As always, snacks and drinks will be provided, and like all Hackaday meetups, bring some cool gear or whatever project you’re working on along with you. This bring-a-hack isn’t a competition, but if it was, we know who would win. Nisan Larea will be attending the meetup, demoing the Wazer desktop waterjet cutter. We caught a glimpse of this machine in San Francisco, and it’s amazing. If you want to see the Wazer waterjet before Maker Faire, this is your chance.
This month’s Hackaday NYC meetup will be at Pivotal Labs, 625 Avenue of the Americas, on Thursday, September 29. It would be really, really cool if you could RSVP beforehand.
This is Hackaday’s pre-game for the World Maker Faire. We’ll be attending, scoping out all the coolest projects and products from this year’s NYC Maker Faire. Find one of the Hackaday crew at the faire, and we’ll hook you up with some swag.
Part performance art and part social experiment, [mocymo]’s Smilemachine V6 helmet is as delightful as it is expressive. The helmet is made primarily from laser-cut MDF assembled around parts from a safety helmet. The display is an Android tablet with fine operation controlled by a Bluetooth mini keyboard, and the helmet cleverly makes use of the tablet’s ability to adjust the display to compensate for head tilt angle. It recently made an appearance at Maker Faire Tokyo, where the creator says the reception (especially by children) exceeded expectations.
There are several interesting things done with this device. One is the handheld controller, which is essentially a mini Bluetooth keyboard. To help allow fine control without needing to look down at the controller, the keyboard sits in a frame with some nuts and bolts used as highly tactile button extensions. By allowing the user to change the physical button layout (and setting up keyboard shortcuts on the device to match) the arrangement can be made more intuitive for the user. Some photos of this assembly are in the gallery after the break.
Another interesting bit is that despite a tablet being right in front of your eyes, it is possible to see out the front of the helmet while wearing it. The solution is completely low-tech: two mirrors form a periscope whose angle can be adjusted by turning a knob on the side of the helmet.
Version 1 of the helmet was started back in 2012; this is version 6 and [mocymo] is already filling out a to-do list for refinements. The nose area is uncomfortable, the angle of periscope is slightly off and the gearing needs to be reworked, among other things. We can’t wait to see Version 7. Video and gallery are embedded below.
I had a great time at Denver’s 3rd annual Mini Maker Faire, which was held inside the Denver Museum of Nature and Science. The official theme this year was “Building the Future” and looking back, I can tell you that they pulled the theme off well. There was a strong turnout in two categories that are crucial to building the future: the growth that comes from education at all ages and the physical places where learning becomes immersive.
The Really Fun Stuff
[Casey] from Caustic Creations were showing off Poison Arrow just in time for season 2 of the BattleBots reboot. Poison Arrow is 250-lb. drum spinner that destroys things at 9,000 RPM. Here’s a nice introductory video shot by their sponsor, Arrow Electronics. [Casey] told me that Poison Arrow will be on the June 30th episode, so set your DVR.
Who knew that Colorado had so many maker- and hackerspaces? Colorado Makerhub, that’s who. They provide a portal to everything maker-related in Colorado, and they were in attendance along with most of the ‘spaces within a 50-mile radius of the city. Denver’s own Denhac brought a huge multiplayer rig that they had built for Comic Con last year. It runs Artemis, a spaceship bridge simulator game that divides up the tasks necessary for successful intergalactic travel. Here’s a video of Denhac member [Radio Shack] describing the game and giving a tour of one of the consoles. The group landed a space in one of the darker areas of the museum, which made the blinkenlights irresistible, especially to boys of a certain age range.
Saturday was the first Madison Mini Maker Faire. In this case, it’s Madison, Wisconsin (sorry Madison, SD I didn’t mean to get your hopes up) where I live. Of course I’m not the only crazy hardware hacker in the area. As soon as I got there I almost tripped over Ben Heckendorn who also lives in the area.
Check out that incredible Giant Game Boy the he was exhibiting. Okay, you think to yourself: Raspberry Pi and an LCD. Wrong! He’s actually using an FPGA to drive the LCD. Even cooler, it’s using an original Game Boy brain board, which the FPGA is connected to in order to translate the handheld’s LCD connector signals to work with the big LCD.
[AvE] noticed someone was having trouble with their Nepeploid Shilden Inversker, and after a sinusoidal lambda deplanarization test, noticed the dinglebop wouldn’t pass through the grumbo. [AvE] is probably just some guy who wears overalls to bed, but he does know a polyfractal magnetorestrictor when he sees one. To wit, he has a novel application of Eularian magnetronics resulting in a friction factor over unity. Game changing stuff here, from the guy who brought you the beer stein made out of an oil filter.
Boldport, and founder [Saar Drimer] are the cream of the crop when it comes to artistic PCBs. Boldport’s catalog and [Saar]’s portfolio include a tribute to [Bob Pease], a beautiful board with multicolor solder masks, and an emergency business card. Now Boldport is doing a beautiful PCB of the month club. It’s called Boldport Club, and each three-month membership gets you three months of pretty PCBs. The shop will also stop taking orders for the Boldport club 25 hours after this post goes live. If you missed the boat on the club, you can still get in on the pretty PCB action – we have the Boldport cordwood puzzle available in the Hackaday store.
The Apple IIgs was the last gasp of the Apple II before that platform was phased out for the Macintosh. Despite being mostly forgotten, except for thousands of units in middle school computer labs until the 2000s, it was a very interesting machine, with a wavetable synth, real multitasking, a GUI, and very high resolution graphics. After 30-odd years the IIgs now has quadraphonic sound. The 4soniq card was introduced at the WOzFest III conference last month, and it will give an Apple IIgs with four channels of audio output.
There’s a lot of stuff happening next weekend, and Hackaday is going to be there. If you’re at the Maker Faire Bay Area, Hackaday is taking over a pub. It’s on Saturday night, so it doesn’t conflict with the bring-a-hack at an undisclosed location on Sunday night. Me? I’m going to hamvention, mostly for the purposes of documenting the two parking lots full of swap meet. Find me and I’ll get you some Hackaday swag.
The first-ever Berlin Maker Faire was last weekend, and Hackaday was there. Berlin’s a city with an incredible creative vibe, so it’s no surprise that there was good stuff on display. What was surprising, though, was how far many of the presenters traveled to be there. I wandered around with a camera and a notebook, and here’s what we saw.
There were plenty of projects and products to be seen at the 2015 World Maker Faire. In the maker pavilion, we found [Rocco Tuccio] showing off Prometheus, his PCB CNC router. Machines like this make prototyping circuits easy. Just place a blank piece of copper clad in the machine, load up your design, and a few minutes later you’ll have a board ready to stuff. Prometheus sports some impressive specs: 7 mil (0.18 mm) trace and space, and a Total Indicated Runout (TIR) of .0001 inches (2.5 micron). Not bad for a spindle turning 40,000 RPM. [Rocco] has spent the last two years designing this machine, and has sourced most of the parts from local US vendors. The unique part of Prometheus is the spindle design. Like many other small PCB routers, Prometheus uses a brushless quadcopter motor for power. Rather than go with a belt system, [Rocco] simplified things to a simple friction drive. The only precision parts he has to worry about are the bearings which hold the cutting bits in place. Prometheus isn’t for sale yet. [Rocco] plans to launch a Kickstarter campaign in the coming months.
A few minutes later we ran into [Victor Aprea] from Wicked Device, showing off the Air Quality Egg V2. [Victor] and his partner [Dirk] ran the design and manufacturing side of the Air Quality Egg, which had a successful Kickstarter campaign back in 2012. The eggs from that campaign can be found online at the project’s website. [Victor and Dirk] have greatly improved on the Egg since then. The biggest update are the sensors. Sensors for ozone, nitrogen dioxide, and sulfur dioxide are now much more sensitive units from SpecSensors. These sensors don’t come cheap though. To keep costs down, [Victor and Dirk] have released three separate versions of the product with different sensor suites. On the connectivity side, the egg is now based upon Wicked Device’s Wildfire, allowing it to connect to WiFi networks. These Eggs mean business too – [Victor and Dirk] obtained permission to co-locate a trio of eggs alongside an official New York State/EPA air quality sensing unit. The Eggs all read within 2 parts per million for carbon monoxide, and 10 parts per billion for sulfur dioxide. As with the original Egg, these devices are open source hardware. Source code is available on Wicked Device’s Github.
