Hackerspace Intro: The Geek Group In Grand Rapids, Michigan

April 27, 2012 by Mike Szczys 9 Comments

We’re happy to see some links rolling in from our call for Hackerspace introductions. This is sort of a reintroduction of The Geek Group. They’ve been around for a while and we’ve featured several interesting projects coming out of the collective (check out this pulse capacitor autopsy). You may remember some tax woes they ran into when the home base was located in Kalamazoo, but they’ve moved past the issue and moved out of town. This is their new location in Grand Rapids, MI and you can get a peek at the tour starting about 4:45 into the video after the break. Be warned, there is some mildly vulgar language in the video in the form of the ‘S’ word (you’re welcome cubicle dwellers).

We hope you’ll look at the video and see that we don’t need to you spend a week in post-production. Give us a tour by video as if we were there in person. Show us what you’re up to and we’ll be eternally grateful.

Hackerspace Intro: Hackerspace.gr In Athens Greece

April 26, 2012 by Caleb Kraft 4 Comments

This is a fitting video to be the first of our Hackerspace introductions. After our call for hackerspace tours yesterday, [Nikos] emailed us to let us know that their hackerspace already had a video ready. While this is more of a general video, explaining the idea behind hackerspaces, we do get to see a little bit of what is going on there. You can catch the video after the break (english subtitled), or head on over to their site to see what is going on at Hackerspace.gr in Athens Greece.

Though this video is very well made, yours doesn’t have to be. We don’t care if you are filming in your basement with 2 other members, showing off a couple projects, we want to see it! If you’re making a video for us, remember that we already know what a hackerspace is, so show us what you are doing!

Hackerspaces And Hackaday

April 25, 2012 by Caleb Kraft 20 Comments

It should really go without saying that Hackday LOVES hackerspaces. We want to support hackerspaces to the best of our ability. There have been many ideas tossed around, like a hackerspace directory, or hackerspace calendar of events, project lists, tool exchange programs, etc. For the short term, we can’t implement either of those in a smooth enough fashion that we think it would beneficial. There are several Hackerspace directories out there, with hackerspaces.org seeming to be the most up-to-date. We even have an “events” area in our forums, though we feel there could be a much better format or delivery device than a forum for that kind of information.

So what can Hackaday do to start helping? Well, the first small step could be to share more information about hackerspaces. We would like to do video tours of your hackerspace. Unfortunately, we don’t have a budget to travel around with a film crew and visit you all. I really wish we did, since I would probably be the one doing the traveling. So what we can offer for now is that you film a tour, showing off some cool projects going on in your hackerspace, and we’ll share the video. Contact me directly at Caleb@hackaday.com to work out the details. Your hackerspace doesn’t have to be a huge one in a big city. We want to help everyone here. If you have a few people gathered and a couple cool projects, we don’t care if you meet in someone’s basement. We want to see what the hacker community is doing!

Toward the end of May I will be spending a few days in Huntsville Al, then a few days in Hilton Head Island SC. I’d love to visit a hackerspace or two while I’m there to do a quick video tour. Again, contact me directly if you’re in those areas.

CoolBot Keeps Your Laser Cutter From Overheating

April 24, 2012 by Mike Szczys 9 Comments

[Charles] wrote in to share the project he just built for the London Hackerspace. He calls it CoolBot, and as the name indicates it’s responsible for keeping the laser cutter from overheating.

At its heart the system is a water pump. It uses a plastic storage container as a reservoir, with an outfeed from the laser tube coming in the top of the lid. [Charles] mounted a temperature sensor using a 3D printed part to anchor it in the center of the return stream. An Arduino clone uses this sensor, as well as ambient room temperature and laser tube temperature sensors to decide when to switch on the cooling pump. As with any hackerspace add-on, this wouldn’t be complete without Internet connectivity so he included an Ethernet shield in the project box. Speaking of, that box uses panel-mount connectors to keep dust and water away from the electronics. But the lid of the controller box also includes a character LCD for quick reference.

Don’t miss [Charles’] explanation of the system in the video after the break.

Kits To Fund Hackerspaces

April 23, 2012 by Adam Munich 8 Comments

[Overflo] recently tipped us about HackerspaceShop; his plan to help fund the Viennese and European hackerspaces by creating a marketplace for electronic kits. The idea is to not only sell kits, but to also create an easy way for others to sell their own kits through the platform, which is pretty awesome if you ask us.

Their kit they sent us to play with is a sun tracking flower developed by [daniel schatzmayr] in the metalab hackerspace. All and all, it’s a pretty awesome kit that’d be perfect for any geeky girlfriend, and of course, it’s arduino controlled. Whether or not that is a good or a bad thing is up to the hackaday trolls to decide, but it does have an FTDI header; something we’d personally like to see on a lot more of these electronic kits.

Currently there’s not to big a catalog on their site but hey, wickedlasers started out as a guy selling modified laser pointers and Hewett Packard started out as two guys selling a better function generator. It’s always awesome when a hacker uses their skills to become an entrepreneur, especially for a good cause.

Good luck [overflo]!

Shocking Use Of Ice Cube Trays

April 16, 2012 by Mike Szczys 13 Comments

Looks like ice-cube trays are once again proving their versatility as this one is serving as the vessel for a home made lead-acid battery. With a collection of uniformly sized non-conductive containers, it makes the perfect base for a set of small cells. This project is the culmination of a Hackerspace class about batteries, and was put together to turn theoretical knowledge into a hands-on lab.

This is a captured image from the low-quality video found after the break. [Carpespasm] describes the setup; the black pieces are lead plates which are bent into a U-shape to straddle two ice-cube compartments. The each end of the plate is dipping into the acid to make the connection. Once assembled the battery was connected to a charger for about two hours. It puts out 8.5V and is tested by powering an LED cube. This works for just a short period and really drives home the lesson that battery concepts are easy to understand, but reliable battery technology is a bit harder to achieve.

CNC’d Business Cards Will Definitely Get You Noticed

April 8, 2012 by Mike Nathan 21 Comments

The guys over at North Street Labs were bored, so they figured why not go ahead and built a CNC machine just for kicks. While they haven’t put up build details on the CNC just yet, they do have some newly milled business cards to show off just how well the machine works.

Part ruler, part LED throwie, we think their new business cards look great. Milled out of thin acrylic sheeting, their cards feature the North Street Labs logo and URL along with 1/32” ruler markings along the top. The card is also fitted with space for a button cell battery and RGB LED, which illuminates the entire card nicely from the side.

They say that the cards take about 5 minutes apiece to make, which is not bad at all. At $0.50 a pop, the cards are not nearly as cheap as those made from cardstock, but when you’re looking to impress what’s a couple of quarters?

Continue reading to see a short video of their CNC-milled business cards in action.
