Hardware Startup Review: Spark

May 12, 2014 by 12 Comments

The Hardware Startup Review - Spark - Hackaday-01

Like it or not, a whole new wave of Hardware Startups is coming our way. Crowd Funding campaigns are making it possible for everyone with an idea to “test the waters”, tech-savvy Angel investors are eager to help successful ones cross over, and Venture Capitalists are sitting on the other side, always on the lookout for potential additions to their “hardware portfolio”. It’s these billion-dollar acquisitions that made everyone jump on the bandwagon, and there’s no going back. At least for now.

That’s all great, and we want to believe that good things will come out of this whole frenzy. But instead of staying on the sidelines, we thought Hackady should get involved and start asking some hard questions. After all, these guys didn’t think they’d be able to get away with some nicely produced videos and a couple of high-res photos, right?

For our first issue, we picked a relatively innocent target – Spark, the team behind the Spark Core development board. By embracing Open Source and Open Hardware as the core part of their strategy, Spark has so far been a positive example in the sea of otherwise dull (and potentially creepy) IoT “platforms”. So we thought we should give [Zach Supalla], CEO of Spark a call.

Hackaday Links: May 11, 2014

North Korean drones! Yes, your local hobby shop has the same aerial reconnaissance abilities as North Korea. Props to Pyongyang for getting v-tail mixing down.

There’s nothing quite as satisfying as the look of a well laid out resistor array, and the folks at Boldport have taken this to a new level. It’s an art piece, yes, but these would make fabulous drink coasters.

Here’s something even more artistic. [cpurola] found a bunch of cerdip EPROMs and bent the pins in a weird chainmaille-esque way. The end result is an EPROM bracelet, just in time for mother’s day. It’s a better use for these chips than tearing them apart and plundering them for the few cents worth of gold in each.

[John] still uses his original Xbox for xmbc, but he’d like to use the controllers with his computer. He never uses the third and fourth controller ports, so he stuck those in his computer. It’s as simple as soldering the controller port module to a connector and plugging it into an internal USB port. Ubuntu worked great, but Windows required XBCD.

[Kerry] has modified an FT232 USB/UART thingy as an Arduino programmer before. The CP2102 USB/UART is almost as popular on eBay, a little less expensive, and equally suited for ‘duino programming. It requires desoldering a resistor and soldering a jumper on a leadless package, but with a fine solder tip, it’s not too bad.

Retrotechtacular: ROTOPARK Is A Futuristic Parking Structure From 40 Years Ago

Pictured above is a functioning model of an automated underground parking structure which was built and used, but obviously it never caught on widely. That makes us a bit sad, as it removes the need to find an empty parking spot every time you use the garage; and having a robot park your car for you seems very future-y.

The gist of the ROTOPARK system is a carousel and elevator system for parking cars. just drive into a single-stall garage at ground level, take your ticket, and walk out the people-hole. The garage stall floor is a sled which moves down an elevator (shown as blue stalls on the left half of the image) to be stored away in the rotating carousels of cars.

Obviously mechanical failure is a huge issue here. What if the elevator breaks? Also, at times of high traffic we think getting your vehicle back out of the system would be quite a bit slower than the “static” parking garages we’re used to. Oh well, maybe some day. Check out the classic marketing video after the break which shows off the concept, construction, and use of the system.

Hackaday Space: The Winners!

May 3, 2014 by 11 Comments

arg-winners

We promise this is the last post about the ARG we ran throughout April to promote The Hackaday Prize. But we’re excited to announce the winners and all the goodies they are going to get!

The Prizes!

Now that the scoreboards are finalized we can announce the overall winners of the Alternate Reality Game and the prizes they will receive!

crazyflie_pageFirst, we’re giving away a Crazyflie Nano quadcopter to each of the people who were the first to post all the details for the first three Transmissions on the Major Tom profile pages.

Transmission 1 Winner

[kline] wins Transmission 1 as he was the first to post all the details from the transmission and did some great work to convert the QR code into an image using Python.

Transmission 2 Winner

[Tyler Anderson] wins this round as he was the first to decode the status message from Major Tom.

Transmission 3 Winner

This was a tough one since we know some people got very close to the answer on IRC but were led down rabbit holes instead, however [Ted] wins as he was the first to finally locate the launch site longitude and latitude hidden in the audio files.

Final Transmission Winner

Printrbot Simple Maker KitNext up we have the winner of the Final Transmission. Someone suggested that when the pixel art contest was over we should 3d print all the entries, so this inspired us to give away a low cost 3d printer that the winner could use to do just that. Therefore we are presenting a Printrbot Simple Makers Kit.

This prize goes to the person at the top of the scoreboard and winner of the pixel art contest [XDjackieXD]. Congratulations and we expect to see your Portal Cube rendered in plastic sometime soon!

Best Overall Contributor

hexyFinally, since this ARG was a team effort and some people put in outrageous amounts of work we decided we should award a prize for Best Overall Contributor.

This was a hard decision as so many people contributed throughout the month. But we feel that the efforts of [Emerica] really stand out, not only was he responsible for figuring out the use of OpenPuff in Transmission 2, he also contributed massively to the Pixel Art Contest and even built a stunning rendition of the Space Needle over the location of Seattle. [Emerica] wins a Hexy the Hexapod robot kit for his contribution, we hope to see many creative uses for this little fellow in the coming months.

Mission Complete.

It may be all over, but we just want to say how much fun putting together this ARG has been and how much it has shown the creativity, ingenuity and pure genius that exists in this community.

It was wonderful to watch everyone come together to work things out and the life that has sprung up in the IRC channel is really great to see. We hope we can all continue to play and build together as we truly believe there is nothing this community cannot accomplish when we come out of our respective sheds and workshops and work together on something.

Thank you all for participating and good luck in with your entries in The Hackaday Prize!

Hackaday Space: Final Transmission Minecraft Puzzles Explained

May 2, 2014 by 10 Comments

This is the last part in our round up of the ARG that we ran throughout April. Just in case you’ve had your head buried in a hole this last week, it was a month-long series of puzzles that lead up to the announcement of the frankly awesome Hackaday Prize. During the week we’ve covered Transmissions 1, 2 and 3 detailing how we put the puzzles together and the things that went wrong. For the final stage we wanted something a bit different. Throughout the ARG we had been inspired by the book Ready Player One, so in this stage we wanted a high score table that people could compete over.

Since we’d managed to get reasonably far ahead of ourselves during Transmission 3 we had just over a week to plan this round. We pitched some ideas around the office for video games we could make with high score tables. None of these really stuck and we soon realized we didn’t have the resources to get the graphic design work done for most games. Someone suggested that we try making a MUD themed around a space port with rescue for Major Tom being the last stage. This seemed like a great idea at first and I began work on it using the RanvierMUD framework. It soon became clear however that writing all the text for a full featured MUD is actually a massive endeavor and I frankly am not that great of a writer.

Hackaday Space: Transmission 3 Puzzles Explained

transmission-3-puzzles-explained

Yesterday we did a run down of Transmission 2 as part of a series of posts covering the ARG that we ran throughout April. Today I’m going to reveal all the details in Transmission 3, how we put it together and what the answers were.

In classic Hackaday fashion we hadn’t planned any of this, so by this point all our initial ideas we already used up and we were now running out of creativity so it was a real slog to get Transmission 3 out the gate. However we somehow managed it and opened Transmission 3 by posting a series of 5 images of space telescopes:

The Hacklet #2

April 30, 2014 by 1 Comment

A new edition of The Hacklet is now available It covers some of our favorite stuff going on in the Hackaday Projects community.

In this edition, we round up a few hacks involving cars. There’s Bluetooth Low Energy connectivity, vehicle telematics, and tools to hack into your car’s CAN bus. If you’ve ever wanted to clear that pesky check engine light without paying the dealer, or unlock your car with a smart watch, these are worth a look.

Next up are a bunch of LED hacks. This starts with a DIY theater light, then looks at a portable DJ booth, finishing off with our Evil Overlords’ own LED visualization platform.

Finally, we check out a new 3D printer design. This one uses polar coordinates instead of the Cartesian coordinate system that most printers use. This gives it the unique ability to print with multiple extruders at the same time.

Once again, let us know what you think of this edition in the comments. Our goal is to keep you entertained with some of the coolest hacks on the site.
