At a science-fiction convention, you queue for hours to hear a bit-part actor describe what it was like on the set of a forgotten sci-fi show. At a science-fact convention, you have a beer with a person who is literally changing the world with a laser cutter, some diodes, and a smattering of Python. Welcome to ElectroMagnetic Field! (I've stolen the subtitle from Ken MacLeod's description of…

My mobile provider - Three UK - offers WiFi calling, but only if you have a phone purchased directly from them. For everyone else, they have a crappy app which hasn't been updated in two years. So, let's break out of their artificial restrictions and get some WiFi calling on the OnePlus 5T! Step-by-step Open your phone dialler app. Dial *#800# You don't need to press send, you should…

Spotted in London, yesterday. A large, Microsoft Windows-powered advertising hoarding has been hijacked. It's not uncommon to see broken-down Windows displays - I run https://windowsisbroken.tumblr.com/ - which is dedicated to pointing and laughing at such mistakes. But this is the first time I've seen a display repurposed for profit! It appears to be running NiceHash Miner Legacy. A…

Amazon Alexa is a fun little bit of kit. But it can be tricky getting it to work with all your smart devices. Not every company has an Alexa skill - just like not every company has an app. Using Flask-Ask it is possible to bring Alexa smarts to a range of previously mute devices. Alexa coding works on "intents" - the following is a simple intent. That is, you can only ask the skill one…

Many years ago, when Foursquare was still cool, I built an app to let people check into chocolate bars. You know, "@edent is eating a Wonka Bar classic. 4/5?" It was a quick and dirty hackday project. Ever since, I've had the hankering to build something a bit more generic. I currently use Untappd to check into beer and Vivino for wine. I'd like to be able to check in to: Artwork Boardgames …

Just me scratching my own itch. I want to create an RSS feed of all the blog posts which I'd published on this day in the past. For example, if today is 21st of November 2016 then this plugin will show blog posts written on 2015-11-21 2014-11-21 2013-11-21 And so on. You can view a demo at https://shkspr.mobi/blog/on-this-day/ Code The code is pretty simple. The WordPress API is fairly …

In September 2016, I was delighted to deliver this talk to ThingMonk 2016. This is the 20 minute distilation of my adventures Singing to my lightbulbs, hacking my vacuum cleaner, finding my car's source code, hacking my electric car, getting hacked by my light switches, securing my security cameras, and a whole host of other IoT nonsense. Huge thanks to Bennycrime for filming, and the whole…

Last year I published details of the BMW i3's API. I've now swapped my i3 for a Renault Zoe - so I thought I'd perform the same exercise. edent's Car@edent_car🔋 100%🚗 76 miles🔌 Plugged in⚡ Not charging⚠ Secured and Locked#RenaultZOE❤️ 1💬 0🔁 020:18 - Sat 15 October 2016 All these API calls can be found by using the Renault ZE Services website.

As regular readers know, I've turned a BLE Beacon into a wireless business card. Physical Web used the Bluetooth beacon standard to continually broadcast not an ID number, but a URL. If you're in my proximity, you can grab my contact details. The one problem with the beacon I have is that it has an exposed button. Every time it got bumped in my pocket, the token would emit a couple of shrill…

I like to tinker. My wife picked me up the new Raspberry Pi Zero. It's an ultra small and ridiculously cheap computer. How small and cheap? They give it away free on the cover of magazines...

Many years ago, as I was wandering around the Louvre, I came across a painting which bore an uncanny resemblance to me! Spooky, eh? Yeah, yeah, it's not the greatest likeness ever, but people who know me seem to think I look like the chap on the left. This got me thinking... Wouldn't it be great if when you entered an art gallery, a computer could tell you which painting you look most like? …

Perhaps the most legendary piece of plastic in the hacker community is the humble "Cap'n Crunch" whistle. The free-in-cereal whistle was able to emit a piercing shriek at 2600Hz - the exact tone required to unlock the US phone network. So, because it's all I seem to do these days, I turned my my trusty RepRapPro and decided to see whether it was possible to 3D print a whistle which could…
