Card Reader Lockout Keeps Unauthorized Tool Users At Bay

May 20, 2018 by Dan Maloney 19 Comments

It’s a problem common to every hackerspace, university machine shop, or even the home shops of parents with serious control issues: how do you make sure that only trained personnel are running the machines? There are all kinds of ways to tackle the problem, but why not throw a little tech at it with something like this magnetic card-reader machine lockout?

[OnyxEpoch] does not reveal which of the above categories he falls into, if any, but we’ll go out on a limb and guess that it’s a hackerspace because it would work really well in such an environment. Built into a sturdy steel enclosure, the guts are pretty simple — an Arduino Uno with shields for USB, an SD card, and a data logger, along with an LCD display and various buttons and switches. The heart of the thing is a USB magnetic card reader, mounted to the front of the enclosure.

To unlock the machine, a user swipes his or her card, and if an administrator has previously added them to the list, a relay powers the tool up. There’s a key switch for local override, of course, and an administrative mode for programming at the point of use. Tool use is logged by date, time, and user, which should make it easy to identify mess-makers and other scofflaws.

We find it impressively complete, but imagine having a session timeout in the middle of a machine operation would be annoying at the least, and potentially dangerous at worst. Maybe the solution is a very visible alert as the timeout approaches — a cherry top would do the trick!

There’s more reading if you’re one seeking good ideas for hackerspace. We’ve covered the basics of hackerspace safety before, as well as insurance for hackerspaces.

Detoured: Caltech’s Hackerspace

April 23, 2018 by Brian Benchoff 1 Comment

Over the last few months, the folks over at the SupplyFrame Design Lab, home to Hackaday meetups, the Hackaday Superconference, and far, far too many interesting tools, have been spending their time visiting workshops and hackerspaces to see how they tick. Staff Designer of the Design Lab, [Majenta Strongheart], recently took a trip down the road to Caltech to check out their hackerspace. Actually, it’s a rapid prototyping lab, but a rose by any other name…

The prototyping lab at Caltech exists for a few reasons. The first, and most important, are the graduate students. This is a research facility, after all, and with research comes the need to make stuff. Whether that’s parts for biomechanical fixtures, seismology experiments, or parts for a radio telescope, there’s always going to be a need to make mechanical parts. The rapid prototyping lab is also available to undergraduates. Many of the courses at Caltech allow students to build robots. For example, when the DesignLab staff was filming, the students in Mechanical Engineering 72 were taking part in Tank Wars, a robot competition. Here, students built little rovers built to climb over obstacles and traverse terrain.

As far as tech goes, this is a real shop. There are vintage knee mills, manual lathes, but also fancy CNC lathes, Tormach mills, and laser cutters galore. The amount of tooling in this lab has slowly accumulated over decades, and it shows. Right next to the bright white Tormach, you’ll find drill presses that are just that shade of industrial green. It’s a wonderful space, and we’re happy the faculty and students at Caltech allowed us to take a look.

You can check out the video below.

When Hackerspace Directors Burn Out

April 18, 2018 by Jenny List 78 Comments

A friend of mine once suggested that there should be a support group for burned-out former hackerspace directors. We could have our own Village of the Damned at summer camps, where we’d sit moodily in the gathering twilight sipping our bourbon and Club Mate and decrying whatever misfortunes came to our space to leave such visible mental scars, or gazing hollow-eyed into the laser-tinged haze and moving gently to the pulse of the chiptune music. “See that’s Jenny over there, she don’t say much“. Hackerspace noir, where the only entry criterion is being crazy enough to stand for election to your space’s board.

There must be spaces somewhere that live in such perfect harmony, in which a happy membership support a board for whom everything falls into place. Maybe the makerspace in [Dr. Seuss]’s Whoville would have that kind of atmosphere, but the reality of life is that every group is made up of both Grinch and Who. Keeping a diverse group of people harmonious is a huge challenge, but that’s what hackerspaces are really about — the people make the space.

There are several defined periods in the gestation of a hackerspace, and at least from where I’m sitting they relate to its member count. Some spaces pass through them all as they grow, while others are lucky enough to reach an equilibrium and spare themselves some of the drama.

If you recognise yourselves in some of the following then you have my commiserations, while if your space hasn’t got there yet or has managed to dodge some of the bullets then consider yourselves lucky.

Dublin Knows How To Bring-a-Hack

April 9, 2018 by Mike Szczys 11 Comments

When on the road, we love to stop by a local hackerspace and connect with the hacker community. On Friday, TOG Hackerspace in Dublin, Ireland opened their doors to host a Bring-a-Hack with Hackaday and Tindie.

The city center of Dublin is anything but a grid. The cobblestone roads meander every which way and are a puzzle of one-way and surprise construction, none of which seemed to faze Google’s navigation algorithms. I was happy to be operating the smartphone instead of the rental vehicle. A big thanks goes to Jenny List for taking on the stress of driving on our refreshments run without coming in contact with people or cars.

You’re likely wondering why the street layout of the city deserves such attention. I’m used to centrally-located Hackerspaces being tight on space, and indeed the members of TOG cautioned us that 50 people would feel cramped. Much the opposite, the pubs, restaurants, hotels, and performing arts centers are not small, nor winding, nor made of cobblestones. Dublin is a fantastic place to party, with plenty of space for us hardware geeks to congregate. TOG itself, which about 20 minutes walk from the central Temple Bar area (where this image was taken), even has a small parking lot which made our beer drop off and pizza delivery a breeze.

A Tour of TOG Hackerspace

TOG is a Gaelic word which loosely translates as “to make”. Declan met us for the beer drop and gave us a tour when we returned for the evening event. The building is divided into several different spaces, starting with an entry area that serves as a meeting space, gaming room, and showcase of projects.

Where you might see prayer flags strung up on an apartment building, we see floppy disks (both the hard and soft variety) strung around the meeting area. Declan has a shamrock of K’nex parts wired up with a microphone controlled RGB LED strip — it’s like a test your strength game to see who can shout the coolest colors.

How would you do on fabric anatomy?

I also really enjoyed the fabric anatomy display that has snaps on each organ and only lights up the labels if you complete the circuits in the correct locations.

These are just the tip of the iceberg. There’s much more after the break so join me for the rest of the tour, and some of the notable hacks that showed up on Friday evening.

Detoured: RF And Film

April 4, 2018 by Brian Benchoff 8 Comments

The technology behind capturing aerial video is so unbearably cool. Not only do you have fancy cameras that cost as much as a car, you also have remote control camera mounts on helicopters and amazing microwave links going to the ground. This isn’t your typical FPV setup on a quadcopter; there are jet turbines and S-band transmitters here.

One of the people behind these amazing aerial shots is [Greg Johnson] of RF Film based out of Whiteman airport in sunny southern California. He’s done work for Black Panther, several fo the Fast & Furious films, Marvel movies, and is working on the new Top Gun reboot. As part of the Supplyframe Design Lab’s Detoured series, lead Staff Designer [Majenta Strongheart] visited RF Film to take a look at what goes into getting high-quality images from aerial video platforms.

[Greg] got his start at a helicopter company in Michigan, and eventually moved up to working for ESPN, shooting video of offshore speedboat races. There’s no other way to do this than by the air, but there are problems. You need to get video to the ground somehow, and that means microwave transmitters. [Greg] learned all of this by simply doing it, demonstrating some hacker cred. In fact, some of the first remote control systems he built were built around sprinkler systems.

Now, [Greg]’s work is significantly more advanced than modified sprinkler systems. He’s making custom hardware for 1080 cameras worn in a hat for drag racing. There are gimbals that roll a camera around its axis, and all of this is custom made in [Greg]’s shop.

There’s a lot of work that goes into producing video for aerial photography, and it’s much more complex than sticking a runcam on a quad. There’s antenna design, FCC regs, and custom robots that point the camera where it needs to be. RF Films is one of the best in the business, and we’d like to thank them for giving us a glimpse into their shop and workflow.

You can check out the video tour of the shop below.

Hackaday X Tindie Meetup In Dublin This Friday

April 3, 2018 by Jenny List 4 Comments

Hackaday and Tindie are coming to Dublin at the end of this week. Join us on Friday night as we host a meetup in the company of our friends at TOG hackerspace. Please RSVP to tell us you’re coming.

This is a Bring-a-Hack style event, so come out for a casual meetup and bring a project to show off. It’s a great way to get conversation started and often the most amazing projects are the ones whose creators imagine them to be inconsequential. Keep them to a manageable size though, space may be at a premium.

We’ll supply beverages and light snacks to oil the wheels, and Hackaday Editors [Mike Szczys] and [Jenny List], Tindie Product Manager [Jasmie Brackett], and SupplyFrame Product Manager [Sophi Kravitz] will be on hand. It doesn’t matter what it is you’ve got to show us, whatever you have we’d love to see it. Thank you to TOG for opening their doors to this event!

Saturday is the Hackaday Dublin Unconference!

Act fast to grab one of the last five tickets to the Hackaday Dublin Unconference this Saturday. All tickets have been sold out, but a few people who had a ticket but are now unable to attend were nice enough to return them so that someone else may take their place. Everyone one who attends should be ready to give a 7-minute talk on what they’re excited about right now. We can’t get through everyone in one day so don’t worry if public speaking mortifies you (but still come prepared). We’ll do our best to get through a ton of presenters. We’ll have food and drink on hand and head to the pub afterward for those still standing that evening! Need proof that this is not to be missed? We did it in London last September and it was epic!

This is Hackaday’s first visit en masse to the Irish capital, and we’re looking forward to correcting that oversight and meeting the masses of our Irish readership. Thanks to the generous support of DesignSpark, the innovation arm of RS Components and the exclusive sponsor of the event, we hare happy to offer Hackaday Dublin Unconference free of charge to all who attend.

We’re excited about what will come from this weekend and are looking forward to it. See you soon!

Water Level Sensors, Alexa In A Fish, And Modular Synths During World Create Day

March 19, 2018 by Mike Szczys 3 Comments

On Saturday we saw a flood of interesting hacks come to life as more than 100 community organized meetups were held for World Create Day. Thank you to all of the organizers who made these events possible, and for everyone who decided to get together and hack.

Students Learning Hardware Design in Islamabad, Pakistan

The students at LearnOBots took on a slew of great projects during World Create Day like a smart medicine dispenser, electronics that control mains appliances, parking sensors, and a waste bin that encourages you to feed it. The group did a wonderful job of showing off their event by publishing several updates with pictures, stories, and video presentations from all the students. Nice work!
