Got a Burning Idea For An EMF Camp Presentation? Now’s Your Chance!

Posted on by

Sometimes the world of tech conference presentations can seem impossibly opaque, a place in which there appears to be an untouchable upper echelon of the same speakers who pop up at conference after conference. Mere mortals can never aspire to join them and are destined to forever lurk in the shadows, their killer talk undelivered.

Thankfully, our community is not like that. There is a rich tradition of events having open calls for participation, and the latest we’d like to bring to your attention comes from the British EMF Camp, to be held at the end of August. EMF, (standing …read more

Altitude Controlled LED Jacket Changes Color as You Climb

Posted on by
When your climbing gym throws a “glow in the dark” party, how can you stand out? For [Martijn], the answer was obvious. He made a jacket adorned with 32 WS2812 addressable LEDs whose color is addressable depending on the altitude to which he has climbed.
The build is centered on an Arduino Pro Mini with a barometric sensor and an NRF24L01 for radio comms. A pair of pockets contain AA batteries for power, and he’s all set to climb.
A base station Arduino with the same set-up transmits an up-to-the-minute reading for ground level temperature, which is compared to the

Impostor Syndrome And Individual Competence

Posted on by

When you attend a very large event such as EMF Camp, there is so much going on that it is impossible to catch everything. It’s easy to come away feeling that you’ve missed all the good stuff, somehow you wasted your time, everyone else had complete focus and got so much more out of the event.

In an odd twist, one of the EMF 2016 talks people have been raving about is very relevant to that fear of inability to take in a festival programme. [Jessica Rose] gave a talk about imposter syndrome. A feeling of inadequacy compared to your …read more

Bone Conduction Skull Radio

Posted on by

There are many ways to take an electrical audio signal and turn it into something you can hear. Moving coil speakers, plasma domes, electrostatic speakers, piezo horns, the list goes on. Last week at the Electromagnetic Field festival in the UK, we encountered another we hadn’t experienced directly before. Bite on a brass rod (sheathed in a drinking straw for hygiene), hear music.

This was Skull Radio, a bone conduction speaker courtesy of [Tdr], one of our friends from TOG hackerspace in Dublin, and its simplicity hid a rather surprising performance. A small DC motor has its shaft connected to …read more

EMF Camp 2016, A Personal Review

Posted on by

If I can offer one piece of advice to the Hackaday readership, it is this: Never, ever, be the sole member of your hackerspace’s board that owns a large station wagon, unless you relish the thought of packing an entire hacker camp village into your vehicle and transporting it halfway across the country in the blazing August heat.

I’ve done my laundry, aired my tent, and just sorted the contents of a brace of Tesco bags into several categories: rubbish, food, camping gear and interesting stuff. As I write this, yesterday was teardown day for Electromagnetic Field 2016, an …read more

EMF Fire Pong

Posted on by

One of the installations that consistently drew a large crowd after dark at EMF Camp 2016 was a game. This wasn’t a conventional computer game though, instead it was a line of gas jets along which a pair of players had to bat a jet of flame between them at ever-increasing speed until one player missed the return. This was the Fire Pong game created by members of Nottingham Hackspace, and though there seems to have been no online write-up of it as yet they have posted enough pictures of its build for us to deduce something of its construction. …read more

TiLDA MKπ, The EMF Camp 2016 Badge

Posted on by

The Scottish Consulate has stamped its last passport, the Dutch fire tower has belched its final flame, and the Gold Members Lounge has followed the Hacienda and the Marquee into clubland oblivion. EMF Camp 2016 is over, so all the 1500 or so attendees have left are the memories, photographs, and festival diarrhoea to remind them of their three days in the Surrey countryside.

Well, not quite all, there is the small matter of the badge.

In the case of EMF 2016 it was called TiLDA MKπ, and since there was a point earlier in the year when it seemed …read more

EMF: You Shall Find Us At The Sign Of The Jolly Wrencher

Posted on by

It’s frustrating, the reluctance of some of my fellow hackspace members to put the cordless drill battery back in the charger after use.  As this is being written I’ve just coaxed enough energy from the drill to make a few holes in a piece of PVC pipe that will form part of an improvised flagpole, and upon that pole will hang Hackaday’s Jolly Wrencher flag at this weekend’s EMF Camp. We’re sharing a village with Oxford Hackspace, and as both your Hackaday scribe and an OxHack member the last week has been a little busy.

In theory it’s a simple …read more

Hackaday Links: July 24, 2016

Posted on by

Right now HOPE is dying down, and most of the Hackaday crew will be filtering out of NYC. It was a great weekend. The first weekend in August will be even better. We’re going to DEF CON, we’ll have people at VCF West, and a contingent at EMF Camp. If you’re going to EMF Camp, drop a line here. There will be Hackaday peeps wandering around a field in England, so if you see someone flying the Hackaday or Tindie flag, stop and say hi.

Raspberry Pi’s stuffed into things? Not all of them are terrible. The Apple Extended keyboard …read more
