If you compare the early PC market for the US and the UK, you’ll notice one big difference. While many US schools had Apple computers, there were significant numbers of other computers in schools, as well. In the UK, pretty much every school that had a computer had an Acorn BBC Micro. [RetroBytes] takes us down memory lane, explaining how and why the schools went with Econet — an early network virtually unknown outside of the UK. You can see the video, which includes an interview with one of the Acorn engineers involved in Econet.
Nowadays, you don’t have to convince people of the value of a network, but back then it wasn’t a no brainer. The driver for most schools to adopt networking was to share a very expensive hard disk drive among computers. The network used RS-422, a common enough choice in Apple computers, spacecraft, and industrial control applications.
Hackaday takes over London at the end of this week. Join us on Friday night as we host a meetup at the Marquis Cornwallis, a pub in Bloomsbury.
This is a Bring-a-Hack style meetup, so grab something you’ve been working on to get the conversation flowing as you enjoy food and drink with members of the Hackaday community from the area. Also on hand from the Hackaday Crew will be [Mike Szczys], [Elliot Williams], [Jenny List], [Pedro Umbelino], and [Adil Malik]. We’re consistently delighted by the many and varied projects that show up — we want to meet you and hear about your project no matter how trivial, or involved. We do suggest you bring something handheld though, as tabletop space will be limited.
We’ve rented the upper floor of the pub and ordered food and fine beverages for all who attend. This is possible thanks to the support of DesignSpark, the exclusive sponsor of the Hackaday UK Unconference.
Tickets for that event have been sold out for ages now, so we’re glad to host a meetup to involve more of the UK Hackaday community. There are still a few left for this Friday Meetup so claim your free ticket now!
Hackaday’s first ever conference in the United Kingdom will take place on September 16th. Get your free ticket right now for the Hackaday UK Unconference!
An Unconference is the best way to put your finger on the pulse of what is happening in the hardware world right now. Everyone who attends should be ready to stand and deliver a seven-minute talk on something that excites them right now — this mean you. The easiest thing to do is grab your latest hack off the shelf and talk about that.
Talks may be about a prototype, project, or product currently in progress at your home, work, or university. It could also be an idea, concept, or skill that you’re now exploring. The point is to channel your excitement and pass it on to others in a friendly presentation environment where everyone will cheer as your story unfolds.
Hackaday doesn’t often have the opportunity to organize live events in Europe which is why we’re so happy to partner with DesignSpark, the exclusive sponsor of the Hackaday UK Unconference. DesignSpark is the innovation arm of RS Components and will have some staff on hand at the Unconference. They share our excitement in bringing together the Hackaday community throughout the UK. It is with their support that we are able to book an incredible venue and offer admission at no cost to all attendees. Hackaday events fill to capacity quickly, so get your ticket now before they are gone.
We have already asked a few of our friends in the area if they will be there. Seb Lee-Delisle who wowed us in Belgrade with his laser projection wizardry plans to be there. James Larsson is part of the crew that started the Flashing Light Prize and will be on hand. Phoenix Perry is always on the cutting edge of where people and technology meet and we can’t wait to hear her talk. Mike Harrison of Mike’s Electric Stuff will be around and likely teasing some secret Hackaday hardware he’s spearheading. James Bruton of XRobots (and a Hackaday Prize Judge) is coming, as is Saar Drimer who you may know as the person behind the beautiful hardware art of Boldport. Several Hackaday editors will be there; Elliot Williams, Jenny List, and I will all be on hand. All that’s missing is you.
We’ll flood into the Culture Space at Canada Water on the east side of London starting at 13:00. Tea, coffee, and snacks will be served throughout the afternoon and we’ll provide dinner as well. Anyone who is still standing when we close the doors at 21:00 is invited to join us at the pub afterward (we’ll get the first round).
As always, Hackaday’s success is based on the community of hackers, designers, and engineers that make it up. Please share the link to tickets on your social media and pester your friends to attend. Most importantly, don’t shy away from this speaking opportunity. We want to hear your story and this is the place to tell it. See you in London in just a few short weeks!
UPDATE: Wow, that didn’t take long. The tickets are claimed, but make sure you get on the waitlist. A lot can change in the next five week’s and we’ll be pestering all ticket holders to be there or give their seat up for someone on the waitlist.
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.
