Hey Elon, three weeks ago I was in Burning Man in the Nevada desert and after I dug myself a nice K-hole I notice that Mars is a lot like the Nevada desert which got me thinking that if we can live here we can live on Mars but then I realized that Mars really isn’t a lot like the Nevada desert because there are toilets here but if we could build toilets on Mars it would be a lot like the Nevada desert? This week Elon Musk unveiled the Interplanetary Transport System at the International Astronautical Congress in Guadalajara. Instead of filling the room with industry experts the highlights of the Q&A session consisted of a woman who wanted to give Elon a kiss onstage and some guy who was super, super high. Discussion of the technical feasibility of a big, heavy window on the Heart of Gold has not appeared anywhere. Zero thought has been given to the consequences of building a civilization consisting entirely of the wealthiest 1% of Earth’s population. I fully support the Interplanetary Transport System; I’m going because this planet sucks.

[FoamieNinja] over on /r/radiocontrol is experimenting with single bladed propellers. Single bladed propellers are the most efficient way of pushing air behind an engine but haven’t really seen widespread use because they’re really weird, and I don’t know if you can do a variable pitch prop like this. You can find these types of props rarely on big-sized aircraft such as vintage J-3 Cubs sporting a 40HP engine. I haven’t seen them on anything bigger.

Next weekend is the Open Hardware Summit in Portland, Oregon. Hackaday is going to be there, and there’s a BringAHack at OSH Park on Thursday. Last year at the summit, the Open Source Hardware Certification was announced. This year, OSHWA is ready to launch their certification program. The takeaway from last year is that Open Hardware Certification will be free, self-certifying, with penalties based on fines for non-compliance.

The ESP32 is here, but most of them are still in a shipping container somewhere in the Pacific. Here’s a breakout board for the Espressif ESP-WROOM-02.

The J-Core is a clean room, open source CPU and SOC. Currently, it’s only implemented in VHDL until someone has a ton of money to burn on an ASIC. Now, the J-Core is supported by Linux. That makes an ASIC just a bit more likely. Thanks [Stefano] for the tip.

MakerBot is not at the New York Maker Faire this year. This is the greatest proof of the imminent failure of MakerBot, but it does deserve some context. In 2009, MakerBot demoed their first printer, the Cupcake, at the New York Maker Faire in Queens, NY. This was, by any reasonable historical reckoning, the introduction of a simple, easy to use, consumer 3D printer to the masses. The current trend of cheap desktop printers began seven years ago this weekend. MakerBot was so successful that it can be argued that Make:, the magazine and the faire, has tried to take credit for the consumer 3D printer ecosystem, simply because they hosted the launch of the Cupcake. Over the years, everyone has tried to ride MakerBot’s coattails. Since then, a few things happened. Last month, MakerBot introduced a new line of (China-manufactured) 3D printers, and they don’t have a booth. The reasons for this could be that Maker Faire is horrifically expensive for any vendor, and MakerBot is going to be at CES next year anyway, but this is it. The MakerBot obituary was not premature. We won.

You know about the Hackaday Superconference, right? It’s the greatest hardware con ever, and it’s happening on November 5+6. Details incoming shortly.

The Hackaday Retro Edition exists. It’s the Hackaday blog, HTML-1-izized for weird and old computers? Why did I do this? Because Google is the quickest page to load on a Powerbook 180. There’s a new Retro Success, this time coming from @LeSpocky and his Nokia 3109c phone from 2008.

This is your official notice. The Open Hardware Summit is less than a month away. It’s going down in Portland, OR. Why Portland? The Vaporwavescene, of course. Hackaday, Tindie, and the rest of the crew will be out in Portland next month getting the latest news on the state of Open Hardware. We won’t be sitting in church pews this year, but then again there is no lady made out of soap.

Speaking of OHS, [Dave] just solved all their problems. The ‘problem’ with Open Hardware, if you can call it that, is that people use it as a bullet point on a sales deck. That neat gear logo can be marketing wank, without any of the sources, schematics, or anything else that makes a project Open Hardware. Last year, OSHWA announced they would be creating a certification process, with a trademarked logo, so they can sue people who don’t post schematics and mechanical designs (slightly inaccurate, but that’s the jist of the program). [Dave] is suggesting keeping the cool gear logo, but adding letters the teeth of the gear to designate what makes something Open Hardware. Add an S for schematic, add a B for a BOM, sort of like the creative commons logo/license. Is it a good idea? If OSHWA keeps using the gear logo for the ‘official’ Open Hardware logo/designation, there’s no recourse for when people misuse it. I’m of several minds.

[Colin Furze] is famous for his zany builds. His latest Youtube is anything but. It’s a shed. Of course, it’s the entry for his underground bunker, but this is a quality shed with a concrete pad, a few bits to keep it off the ground, and insulation. The roof is slate (because why not?), but if your design decisions are based on the phrase, ‘you only live once,’ copper may be a better choice.

The ESP32 has been released. The ESP32 is the follow-on to the very popular ESP8266. The ’32 features WiFi and Bluetooth, dual core processors, and a few undisclosed things that will make it very interesting. You can buy ESP32 modules right now, but no one has them on their workbench quite yet. To get you started when they finally arrive, [Adam] created an ESP32 KiCad Library for the ESP32 chip, and the ESP32-WROOM and ESP3212 modules.

The Open, Hackable Electronic Conference Badge

Electronic conference badges have been around for at least a decade now, and they all have the same faults. They’re really only meant to be used for a few days, conference organizers and attendees expect the badge to be cheap, and because of the nature of a conference badge, the code just works, and documentation is sparse.  Surely there’s a better way.

Enter the Hackable Electronic Badge. Ever since Parallax started building electronic conference badges for DEF CON, they’ve gotten a lot of requests to build badges for other conventions. Producing tens of thousands of badges makes Parallax the go-to people for your conference badge needs, but the requests for badges are always constrained by schedules that are too short, price expectations that are too low, and volumes that are unknown.

There’s a market out there for electronic conference badges, and this is Parallax’s solution to a recurring problem. They’re building a badge for all conferences, and a platform that can be (relatively) easily modified while still retaining all its core functionality.

One more go at new enclosures for the Amiga 1200. Yes, it’s a Kickstarter campaign, and we mentioned a similar the same campaign last month. The previous campaign received a little more than half of the desired funding in a 30-day campaign. The new campaign received half its funding in a week. The only difference? Now you can put a Raspberry Pi in a newly manufactured A1200 case. And they say Raspberry Pi consumerism isn’t a thing…

Cheap SLA printing service. [Ian] and Dangerous Prototypes have made a name for themselves with dirt cheap, acceptable quality PCBs. Now they’re going for custom prints on a resin machine. It’s $0.95 per gram (density is 1.3g/cc). That’s cheap.

[James Willis] built a floppy drive orchestra. There are 16 drives in this orchestra, all controlled by an FPGA. Here’s the writeup.

Here’s a video overview of a real, huge, rideable hexapod robot. ‘Wow’ is just about the only thing we got for this.

Western Digital introduced a hard drive made specifically for the Raspberry Pi. It’s a hard drive with a USB interface, and a USB cable that connects to the Pi, the drive, and a power adapter. In other news, externally powered USB hard drives exist. You can buy a 2TB drive for the price of the 1TB PiDrive. What was that thing about Raspi consumerism?

Next week is the Open Hardware Summit in Philadelphia. We’ll be there (or rather, I will). We’ll have a post on the OHS badge up on Monday. Would anyone like to go see the lady made out of soap? It’s right around the corner from the venue.

Free Hackaday stuff at next week’s Open Hardware Summit

supply-frame-at-ohs-2013

If you’re headed off to the Open Hardware Summit next week we’ve got some free swag for you. Readers paying any attention know that Hackaday was acquired by Supply Frame over the summer. There had been some nervousness in the comments about what this all means. But I think you’ll agree it’s a good sign that Supply Frame is one of the major sponsors of the event at the ‘FANATIC’ level.

Several of the Supply Frame guys will be attending (which makes me jealous since I want one of those ePaper display badges so badly!). Details haven’t quite firmed up yet, but we believe there will be a Supply Frame booth were you can stop by, chat, and see if they’ve got any Hackaday T-shirts left to hand out.  I don’t think they’ll run out of stickers so you won’t go away empty handed.

Also ask them for a beta code for the hush-hush new online tool which they’ve been working on. I got a preview when I visited their headquarters in Pasadena last week. It’s something that EE and hobby electronics enthusiasts will appreciate as it simplifies the planning and part choosing process of a design. Actually, now that I think of it, it solves a problem I’ve heard [Dave Jones] rant about before on the Amp hour. Obviously I’m under a bit of an info embargo until they get the service fully online but I’m sure we’ll cover it once they do. Incidentally, one of the devs on this project — [Ben Delarre] — founded CircuitBee.

Our own [Eric Evenchick] will be on hand as well. He’s still networking for future employment so you might not find him just sitting at the SF booth. He will have Hackaday stickers to hand out as well since I felt bad about not sending swag along with him to Def Con. Look for his recollection of the event once it is all wrapped up.

Worry not if you can’t attend OHS. [Brian Benchoff] is planning a trip to World Maker Faire later in September and he’ll be packing a stash of freebies as well!
