Twittering Wall Switch Lets Dutch Hackers Know When It’s Time To Play

March 8, 2011 by Mike Nathan 27 Comments

Hack42, a hackerspace in Arnhem, Netherlands recently moved into some new digs, and they wanted an easy way to let their members know whether they were open or not. Fixed hours of operation typically do not fit this sort of organization, so that was out of the question. Instead, they built a switch into the wall** that will let their members know when they are open for business.

The switch separates the TX and RX pins of two Ethernet ports that reside in an old access point embedded in the wall. When the hackerspace is open, the switch is thrown and the circuit is closed. A cron job checks the state of the eth1 port once a minute, sending the “Open” status message to Twitter and IRC once it notices the status change. When the switch is thrown again and the eth1 port goes down, a “Closed” message is broadcast.

It is a simple but cool hack, and quite befitting of a hackerspace.

KiwiDrive HouseBot

February 22, 2011 by Mike Szczys 12 Comments

Forskningsavdelningen, a Swedish hackerspace, had a hackathon last weekend and the KiwiDrive HouseBot is one of the items that resulted from the group effort. They set a goal to use standard, easy to obtain parts, so that the robotic platform would be accessible for reproduction by individuals or at other hackerspaces. The three-limbed device rolls around on a triad of omni-directional wheels -which are probably the hardest part to source but you can always print your own. An Arduino Uno was used as the hardware interface, driving the three stepper motors for locomotion.

It’s not pictured above, but the fourth generation of the little guy also includes a webcam. The camera rides in the center of the body and is mounted on a servo. This makes it possible to turn the camera, meaning there’s no real front or back to this design. Future plans include adding an on-board computer (this is larger than it appears) and implementing emoticons on an 8×8 LED matrix, presumably so you can tell how the bot is feeling today.

Mitch Altman Hosts A Tour Of Noisebridge

January 27, 2011 by Mike Szczys 17 Comments

[Mitch Altman] just popped up once again (seriously, this guy is everywhere!) in a video tour of Noisebridge, and hackerspace he co-founded in San Fransisco. The space is 5200 square feet and they’ve managed to cram a lot of different uses into it. There’s areas for computers and electronics, crafting and sewing, a dark room , a machine shop, a full kitchen, as well as classrooms and other gathering places.

He talks about what a hackerspace is and what goes on in San Fran before going off on a little tour of the hackerspace movement. His recollection pins the Chaos Communications Camp as the impetus behind an initial push for these community spaces popping up in the US. It’s a fun five-minutes to watch so check it out.

Five Free Evalbots

November 18, 2010 by Joseph Thibodeau 12 Comments

If you’re a member of a hackerspace and you’ve been hoping and wishing for an evalbot to tear apart with your bare hands, you’re in luck! [Dave Bullock] is giving out five evalbots to five lucky hackers chosen at random. We thought that the $125.00 deal we saw the other day was good but this is right outta town!

The draw is on Black Friday, so you’ve got a few days to submit your details. We’ve only had a few posts about the evalbot to-date covering the initial examination of the hardware and a USB power modification. We’re interested in seeing where people take this, and we’d love to follow how each of these free ‘bots turns out. For those already working on an evalbot, keep it up and take lots of pictures!

Hacker Housing – Rally To Restore Sanity

October 25, 2010 by James Munns 44 Comments

HacDC, Washington DC’s own hackerspace has been kind enough to open their doors (and floors) to fellow hackers planning on visiting DC this weekend for the upcoming Rally to Restore Sanity. They are taking registrations now, and space is limited, so act fast. They have a suggested donation of $20 a night, which will get you floor space and breakfast each morning, as well as the warm feeling of supporting a community based Hackerspace. Details can be found on their registration page, and please make sure you read the rules before registering. Thanks again to HacDC for supporting the Hacker community!

In other news, Hack a Day will be at the Rally, so keep an eye out for the writers wearing the Hack a Day shirts, as well as the HackaDay Twitter. If you get seen with one of us, you might just make it to the fan gallery. We will also be handing out some HackaDay Swag if you catch us soon enough on Saturday.

Tokyo Hackerspace – Akihabara Station Video Tour

September 25, 2010 by James Munns 32 Comments

This is the kind of footage that makes our mouths water here at Hackaday. [Akiba] of Freaklabs has been kind enough to take us all on a video tour of Akihabara Station, a treasure trove for electronics hackers located in the Chiyoda ward of Tokyo. The highlight includes surplus stores, specialty electronics shops, and enough silicon to bring an engineer to tears. Rather than waste time reading about it, follow the link and check out the videos in stunning 720p.

Hackers in other parts of the world, what kind of stores and marketplaces do you have like this? Send us your pictures and videos of local marketplaces that cater to your hacking needs so we can show them off.

Hackerspaces Sprouting Up Around The Midwest

September 19, 2010 by Mike Szczys 19 Comments

[Chris Cooper] wrote in letting us know that this weekend is the grand opening of QC Co-Lab, a hackerspace in Davenport, Iowa. They kicked the weekend off in grand fashion on Friday by sand casting bronze medallions with a blast furnace. The 4000 square foot facility has plenty of room for new members so if you’re in the area check it out. It’s not too late to join in on the tail end of the festivities.

Sector67 is also making plans for its grand opening. The Madison, Wisconsin based hackerspace will officially open on October 15th. There was a strong turnout for the first viewing of the facilities on September 7th (see for yourself), with plenty of building, arranging, and accumulating to be done before the official start. [Chris Meyer] has been working hard to get the organization off the ground, acquiring several grants, and working with the School Factory (something of a quick-start incubator for hackerspace-type non-profits). Want to see more? Thanks to [Andrew Seidl] you can peruse a set of quality photos from the event.
