VCF

This weekend takes some of the Hackaday crew to the Vintage Computer Festival East in Wall, New Jersey. There’s going to be lots of cool stuff, some dork walking around handing out Hackaday t-shirts and stickers, and more awesome retro computation devices than you can shake several sticks of RAM at.

On the agenda for Friday are a host of talks that include bootstrapping CP/M, assembly programming, disk imaging, and a talk from our very own [Bil Herd] on how to not kill yourself with a CRT monitor.

Saturday is when things really heat up with exhibits including a PDP-8, a 1960s UNIVAC, Chromeco Dazzlers, VAXxen, and a whole slew of computers that weigh less than several hundred pounds. There’s even a real Apple I. Seriously. There are also workshops that include some really obscure work from the late, great [Jef Raskin], and more talks, including [Dave Haynie]’s recollections of Commodore’s circling the drain.

The VCF is hosted at InfoAge, an exceptionally cool vintage technology treasure trove that’s more than worth the visit, even if there weren’t a vintage computer festival going on this weekend. We caught up with the InfoAge guys a while back, and needless to say, if you come, you’ll have fun.

If you see somebody walking around with a Hackaday t-shirt on, be sure to tell them you’re a fan. If they don’t know what you’re talking about, ask them who they got the shirt from. Regular updates to follow, including a video of someone loading the Hackaday Retro site with an Intel 4004 microprocessor. I didn’t think that was possible either.

Oh, watch our Twitter or something. That’s a thing now.

Telepresence Robot Proves It’s A Small World After All

March 27, 2014 by Adam Fabio 18 Comments

jolvoy [Chris] works as part of a small team of developers in Cambridge, Massachusetts in the US. [Timo], one of their core members, works remotely from Heidelberg, Germany. In order to make [Timo] feel closer to the rest of the group, they built him a telepresence robot.

It was a link to DoubleRobotics that got the creative juices flowing. [Chris] and his team wanted to bring [Timo] into the room, but they didn’t have a spare $2499 USD in their budget. Instead they mated a standard motorized pan/tilt camera base with an RFduino Bluetooth kit. An application running on [Timo’s] phone sends gyroscope status through the internet to the iPad on the robot. The robot’s iPad then sends that data via Bluetooth to the RFduino. The RFduino commands pan and tilt movements corresponding with those sensed by the gyroscope. A video chat application runs on top of all this, allowing [Timo] to look around the room and converse with his coworkers.

All the source code is available via GitHub. The design didn’t work perfectly at first. [Chris] mentions the RFduino’s Bluetooth API is rather flaky when it comes to pairing operations. In the end the team was able to complete the robot and present it to [Timo] as a Valentine’s Day gift. For [Chris’] sake we hope [Timo] doesn’t spend too much of his time doing what his homepage URL would suggest: “screamingatmyscreen.com”

Facebook To Buy Oculus VR

March 25, 2014 by Adam Fabio 103 Comments

Facebook has agreed to purchase Oculus VR. The press values the deal at about $2 Billion USD in cash and stock. This is great news for Oculus’ investors. The rest of the world has a decidedly different opinion. [Notch], the outspoken creator of Minecraft, was quick to tweet that a possible rift port has now been canceled, as Facebook creeps him out. He followed this up with a blog post.

I did not chip in ten grand to seed a first investment round to build value for a Facebook acquisition.

Here at Hackaday, we’ve been waiting a long time for affordable virtual reality. We’ve followed Oculus since the early days, all the way up through the recent open source hardware release of their latency tester. Our early opinion on the buyout is not very positive. Facebook isn’t exactly known for contributions to open source software or hardware, nor are they held in high regard for standardization in their games API. Only time will tell what this deal really means for the Rift.

The news isn’t all dark though. While Oculus VR has been a major catalyst for virtual reality displays, there are other players. We’ve got our eggs in the castAR basket. [Jeri, Rick] and the rest of the Technical Illusions crew have been producing some great demos while preparing CastAR for manufacture. Sony is also preparing Project Morpheus. The VR ball is rolling. We just hope it keeps on rolling – right into our living rooms.

Fluke Issues Statement Regarding Sparkfun’s Impounded Multimeters

fluke-reponds-to-sparkfun-dmm-impounding

Fluke just issued a response to the impounding of multimeters headed for market in the United States. Yesterday SparkFun posted their story about US Customs officials seizing a shipment of 2000 multimeters because of trademark issues. The gist of the response is that this situation sucks and they want to do what they can to lessen the pain for those involved. Fluke is providing SparkFun with a shipment of genuine Fluke DMMs which they can sell to recoup their losses, or to donate. Of course SparkFun is planning to donate the meters to the maker community.

Anyone with a clue will have already noticed the problem with this solution. The impounded shipment of 2k meters will still be destroyed… eh. The waste is visceral. But good for Fluke for trying to do something positive.

Before we sign off let’s touch on the trademark issue for just a moment. We can’t really blame Fluke too much for this. The legal crux of the matter is you either defend your trademark in every case, or you don’t defend it at all. In this case it was the border agents defending the filing, but for ease of understanding we’ll not go into that. On the other hand, speaking in general business terms, the way things are set up it is advantageous to acquire a trademark specification that is as broad as possible because it helps to discourage competitors from coming to market. So trademark is good when it keep hucksters from trying to rip off consumers. But it is bad if applied too broadly as a way of defending a company’s market share.

Where does Fluke come down in all of this? Who knows. There is literally no right answer and that’s why the discussion around yesterday’s post was full of emphatic arguments. A Fluke meter is a cream-of-the-crop device and they have the right (and obligation) to ensure that reputation is not sullied. SparkFun serves a market that probably can’t afford a Fluke at this time but may some day in the future. And this is the reason we can feel okay about this outcome.

Multimeters Without A Country: Fluke’s Broad Trademark Bans Yellow Multimeter Imports

March 19, 2014 by Mike Szczys 249 Comments

Check out this SparkFun Digital Multimeter. Does it make your blood boil to see them ripping off Fluke by using the color yellow? From SparkFun’s side of the story that’s exactly what’s happened here. They have a shipment of 2000 of these things stuck in customs. The trademark being infringed upon can be found in their article. Fluke owns the trademark on multimeters with a dark face and yellow border. Great. This seems like a wonderful idea, right up there with Apple owning tablets that are shaped like a piece of paper.

Okay, so if you’re not crying big fat tears for Fluke being taken advantage of in this way let’s talk about more immediate issues than fixing trademark, patent, copyright, and all of the other screw-the-little-guy type of laws (not that SparkFun is necessarily the little guy but you know what we mean). The DMMs sitting in a warehouse are costing SparkFun $150 per day. We believe they have no option of choosing a warehouse with a lower cost as we must be talking a pallet or two, right? The only two options they do have are shipping them back to China where they were manufactured, or having them destroyed. The former will cost more in re-import tariffs than the cost of the product, and the latter comes with a $150/hour disposal fee and no metric on which to judge how long it would actually take. We hate seeing this kind of waste, but sure enough 2000 DMMs are headed for the shredder in a couple of days.

We know you already have your flaming sword in hand, but simmer down for just a second. Fluke makes great products, ask anyone. And companies the world over defend their trademarks. Hopefully there will soon be a positive response from Fluke on this one. If you would like to politely encourage them to do the right thing we found Fluke’s Facebook page URL in the SparkFun comments thread. Both are worth browsing.

Hackaday In Shanghai: Electronica And A Gathering

Whether you live in Shanghai, are at Electronics China representing your company, or by dumb luck just happen to be in town this week you can meet some of the Hackaday crew and score yourself some sweet swag.

Anyone in town on Thursday night will want to get a ticket to Hackaday: The Gathering. Right now it’s all sold out, but we hope anyone with a ticket who is unable to use it will cancel so that another may take your place. Free food, drink, t-shirts, stickers, and other swag await… no wonder the tickets are already gone!

The Electronica China conference started Tuesday at Shanghai New International Expo Centre, but it runs through Wednesday and Thursday as well. We’re attending, but we don’t actually have a dedicated booth. Hackaday is piggybacking with EEFocus, the Chinese contingent of our parent company. Both [Matt] and [Alek] will be hanging around the EEFocus booth (#W3.3686) shucking out hackaday T-shirts if you ask for one. Before he left, [Matt] mentioned that he’s excited to attend lectures on connected medical devices, the Automotive and EV boards, as well as the embedded systems forum.

MRRF: Repables, The Nonprofit 3D Object Repository

March 17, 2014 by Brian Benchoff 40 Comments

Repables

There’s a problem with online repositories of 3D printable objects: The largest repo, Thingiverse, is generally looked down upon by the 3D printing community. Thingiverse, owned by Makerbot, has seen protests, and calls for a an alternative repository. A few people have stepped up to provide a better Thingiverse, but these alternatives are either connected to specific 3D printer manufacturers like Ultimaker’s YouMagine, or have done some shady things with open source licenses; Defense Distributed’s DEFCAD, for example.

Repables, launched at the Midwest RepRap Festival this last weekend, hopes to change that. They are the only repository of printable objects and design files out there that’s backed by its own nonprofit LLC. It’s free for anyone to upload their parts and share, without the baggage that comes with an ‘official [company name] .STL repo’.

Just about everything can be hosted on Repables – .STL files for printable objects, .DXF files for laser cutter files, and even PCB files and Gerbers for circuit boards. Now, .STL files are able to be rendered in the browser, with support for viewing other formats coming soon.

It’s a really great idea that solves the problem of printer manufactures building their own hosting sites and the segmentation that ensues. It’s also headed up by a Hackaday alumnus, [Gerrit Coetzee]. We’re everywhere, it seems.
