Beer And Hacks In London and Beyond

We’ve been all over the UK this month, our most recent Hackaday gathering just two nights past. With much hardware and hacker show and tell (recounted below) I wanted to make sure nobody missed the chance to join in as we’ll be in Bletchley on Saturday and in Cambridge on Wednesday. Whether you need more convincing to walk out the door and join in the fun, or just want to the see the excellent hardware so far displayed, keep reading to share in the fun from Wednesday night.

London pubs have an unfavourable image among provincial folk, one of being strange neon-lit places populated by vast crowds of very loud people in suits drinking cheap wine at expensive prices. The truth is though that the capital’s pubs are as diverse as those anywhere else in the country, from shabby quiet backstreet boozers with their aged customers nursing pints of Fullers to achingly hipster faux-Victorian gin-palaces in which young men sporting preposterous beards they’ll regret in five years time drink microbrewery ales you won’t have heard of served in glass tankards. On a hot August evening the patrons spill out onto the pavement and provide a handy reference to the would-be drinker as to the nature of the establishment.

This warm-evening exodus served our community well night before last, for when a group of Hackaday readers and Tindie sellers converged upon a pub in Fitzrovia there was enough room to reach the bar and though it was hardly quiet we could at least discuss the things we’d brought along. My colleague [Jasmine] had organised the event and was on hand with a pile of stickers and other swag.

A select group of hackers and makers made the journey. Some of them, such as my friend [David], I had encountered frequently online but never met in person so it was good to put a face to a name, while others I knew only by the reputation they had garnered through the projects they’d put on Hackaday.io or Tindie. I will undoubtedly fail to mention a few names in this quick round-up of a few of the projects, so before I start I would like to thank everyone for coming along and making it such a good evening.

Electric Stuff from Mike’s Workshop

Most visible because of an extensive range of very bright LED projects was [Mike], of [Mike’s Electric Stuff] fame. His PCB density was impressive, though he did admit to having a pick-and-place machine. Especially useful for those large LED matrices. Of note was a pentagonal LED screen with integrated camera, originally part of an LED screen polyhedron. This board offered a rare glimpse of a Raspberry Pi Compute Module in the wild.

Scope Probe Sans Pound Sink

Opposite me for most of the evening was [Leonerd], with his oscilloscope current probe adapter. This board as you might expect contains a very low value shunt resistor and an amplifier, allowing the accurate measurement of low current transients without laying down the GDP of a small country to buy one from a high-end test equipment manufacturer. I was party to a very interesting conversation between him and [Mike] on the subject of instrumentation amplifiers, something of personal interest from my experience with RF test equipment.

A Wild Z80 Appeared

Also present was [Spencer] with his RC2014 Z80-based computer. He’d brought along the fully tricked-out version with keyboard and screen, and had it running a fractal graphic generator written in BASIC. It’s a project that touches a spot in the heart of people of a certain age, if your first computer came from Sir Clive Sinclair then maybe you’ll understand.

The value of the evening was not solely in the kits and projects on display though. Whenever you get a group from our wider community together in a convivial environment the creative discourse flows in unexpected direction, knowledge is shared, and new ideas are formed. Part of the global Hackaday and Tindie community got to know each other yesterday evening, and from that will come fresh projects. They may not necessarily change the world, but everything has to start somewhere.

This event was one of a short series following our successful bring-a-hack at EMF Camp. We were very pleased to see the projects people brought along, they comprehensively eclipsed the little radio board that was my offering. The run of UK events isn’t over, we have ones coming up at Bletchley and Cambridge, and as always keep an eye on the Hackaday.io events page for global events within our community.

Hackaday Links: August 7, 2016

The Starship Enterprise (no bloody A, B, C, or D) recently got a makeover. It was donated to the Smithsonian, and the workers at the Air and Space Museum took it apart and put it back together. Why? It’s the 50th anniversary of TOS. Hopefully the new show will be using some practical effects.

After years of trying, we’ve finally attained max buzzword. Here’s a pentesting hacker quadcopter drone, “a hacker’s laptop that can fly.” Why would anyone do this? Because, “You need to be close to the wireless signal to be able to read it. [Danger Drone] removes that barrier of physical access.” For just $500, you can do the same thing a coat hanger yagi can do. Amazing.

Q2 reports for 3D printer companies! Lulzbot is going gangbusters yet again. We’re looking at the greatest success of Open Source Hardware here. Stratasys, on the other hand, lost less money in Q2 2016. That’s their good news.

About a year ago, we heard about an LCD that was one inch high and ten inches long. That’s bizarre, but great for rackmount gear. The company behind this weird LCD is updating this weird and wonderful LCD and giving it touchscreen capability.

On this week’s edition of, ‘you’re going to cut your arm off with that thing’, here’s an angle grinder converted into a chainsaw.

A few weeks ago, we posted a link to this video, demonstrating an absurdly clever method for creating a mold for a fiberglass dome. You can just use a pendulum and a pile of dirt. Now, the mold for this fiberglass dome is complete. [J Mantzel] has already pulled 1/8th of his gigantic fiberglass sphere out of his mold, and there are only seven more to go. After that, he’ll find out if these sphere sections actually line up.

UK peeps! Hackaday and Tindie are doing a London Meetup! Details to come, but follow the event page on Hackaday.io.

I arrived in Vegas a day (or two) early for DEF CON. Instead of contemplating the banality of existence on the strip, I decided on a meetup at the grave of James T. Kirk. The meetup was a huge success. Walking two miles in 115° heat was not a great idea, but I didn’t die.

LEDs Strips Tell You the Trains Aren’t Running

[James] is a frequent user of the London Underground, a subway system that is not immune to breakdowns and delays. He wanted a way to easily tell if any of the trains were being disrupted, and thanks to some LEDs, he now has that information available at a glance without having to check a webpage first.

Inspired by the Blinky Tape project at FT Engineering, [James] thought he could use the same strip of addressable LEDs to display information about the tube. A Raspberry Pi B+ gathers data from the London Underground’s TfL API and does a few calculations on the data. If there is a delay, the LEDs in the corresponding section of the strip will pulse, alerting the user to a problem with just a passing glance.

The project is one of many that displays data about the conditions you’ll find when you step outside the house, without having to look at a computer or smartphone. We recently featured an artistic lamp which displays weather forecasts for 12 hours into the future, and there was an umbrella stand which did the same thing. A lot is possible with LEDs and a good API!

Hackerspace Tours: London Hackspace

On the way back from Hackaday Munich a couple of us got the chance to stop off in the UK, so we thought we’d take the opportunity to visit London Hackspace. With close to 1100 members and more than 6500 sq ft of space over two floors, it has to be one of the largest hackerspaces we’ve seen. [Russ Garrett] and [Jasper Wallis] were kind enough to show us around.  Continue reading “Hackerspace Tours: London Hackspace”

Radio built from the London Underground map

We love it when PCB artwork is actually artwork. Here’s one example of a radio whose layout mimics the map of London’s subway system.

The build is for an exhibit at the London Design Museum. They have an artist in residence program which allowed Yuri Suzuki time and resources to undertake the project. He speaks briefly about the concepts behind it in the video after the break.

The top layer of copper, and silk screen was positioned to mirror the subway lines and stops on a traditional transportation map. Major components represent various transfer hubs. In this way he hopes the functioning of the circuit can be followed by a layman in the same way one would plan a trip across town.

This may be a bit more abstract than you’re willing to go with your own projects. But there are certainly other options to spicing you track layout.

Robot Strippers not too enticing

We really aren’t sure what the statement is here.  This is one of the displays at the MuTate London Exhibition. There is tons of stuff to see there, from interactive displays to giant art-piece vehicles. This specific display seems to have garnered the most attention though. we can understand the megaphone headed flailing DJ, but what is with the CCTV camera heads?
