Hackaday at Maker Faire

hackaday-at-makerfaire-2014

If you are planning your trip to Maker Faire Bay Area — May 17th and 18th — why not hunt down the Hackaday crew? We’ll be packing a ton of swag to give out to anyone who asks for it. But ideally we’d like to show off the best hardware we can find so don’t come empty-handed!

Want your Maker Faire stuff featured on Hackaday? You can Tweet in advance to let us know when you’ll be there and what you’re bringing. You can also track us down during the weekend as we’ll be frequently Tweeting our locations. Here is the contact list and information on some festivities we’re planning:

Hackaday Scouts For Hacks at SXSW

had_sxsw-2014

It seems like everyone is going to South by Southwest this year. We even heard about it on The Today Show this week. But we still have hope that there’s awesomeness to be found. A few of our crew will be there this year and they’re on the lookout for something special. The festival starts on Friday and runs more than a week to the following Sunday but our guys will be on the ground Sunday, March 9th through Tuesday the 11th.

Sure, we’ll take a gander at the interactive hardware areas, but preliminary research tells us these may be watered down to the lowest common denominator. What we really want to see is if a Burning-Man-like culture is beginning to coalesce around SXSW. Are you carrying around your own hacked hardware at this year’s event? Do you roll up in a custom party-mobile and spend the week trying to keep the 24-hour tailgate alive with your fold out pig roaster and awning-based entertainment system? We’d like to check that out.

[Eren], [Alek], and [Ivan] are handling coverage of the event. They’ve been killing themselves making Hackaday Projects an awesome place to share and interact. What they wanted was a bit of down time, but handing out T-shirts and Stickers in exchange for a look at your hacks doesn’t get in the way of that. Connect with them on Twitter using the hash tag #HaD_SXSW. They’ll be using it to tweet their activities but of course it works both ways. Your best bet of just crashing into these guys is to check out [Alek's] talk on StageTwo.

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!

POV fan EEPROM hack

pov_fan_eeprom_hacking

Hacking with Gum got their hands on one of the persistence of vision display fans that Cenzic was giving away at Blackhat this year. It’s not the biggest fan-based POV display we’ve seen but it’s still a fun device to tinker with. They hacked into the EEPROM on the device in order to change the message the fan displayed.

This is very similar to the other EEPROM reading/writing we’ve seen recently. Hacking with Gum read the data off of the EEPROM and then disassembled it to discover how the message data is stored on the chip. This was made easier by noting the messages displayed when the fan is running. The first byte of data shows the number of words in the message, then each chunk of word data is preceded by one byte that represents the number of letters in that work. Data length was calculated based on the number of pixels in each display character. Once he knew the data-storage scheme, it was just a matter of formatting his own messages in the same way and overwriting the chip.

This is a great write-up if you’re looking for a primer on reverse engineering an unknown hardware system. If you had fun trying out our barcode challenges perhaps deciphering EEPROM data from a simple device should be your next quest.
