Reflections on #EMFcamp - a Science-Fact Convention


Terence and Liz in front of Lasers at emfcamp.

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.

Enabling Voice-Over-WiFi on the OnePlus 5T and Three UK


VoWifi Logo on the top of the Android display.

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 […] Read More

Advertising Screens Hacked To Mine BitCoin


The display shows a windows desktop with a variety of icons. There is a window open

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 […] Read More

Creating a generic, open source, check-in app


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 […] Read More

An "on this day" plugin for WordPress

Reverse Engineering the Renault Zoe API


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. ? 100%? 76 miles?

Inside a Physical Web BLE Beacon


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 […] Read More

Raspberry Pi Zero Hidden In An Xbox Controller


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... In related news, @summerbeth is the best wife of them all! #PiZero pic.twitter.com/utsF2m13jo — Terence Eden (@edent) November 27, […] Read More
