Building an ersatz scanning table


A tripod hooked on a tub.

I found a bunch of my old school-books that I wanted to digitally capture. I do have a flatbed scanner, but most of my 1980s workbooks were far too large for it. So I decided to build a cheap scanning table. Ingredients Old Phone Tripod - £8. White table Selfie-stick button! - £2 The Bluetooth […]

If you think you've spotted something that's not listed here, or think I've made a mistake, drop it in the comments. You can follow along with all 10 series. Rose From the start […]

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 […]

Interesting Failures - Group Calling


Another in an occasional series of blog posts where I discuss products I've worked on which failed. It boiled down to this. Was there a way we could make normal people want to be on a conference call with their family and friends? Let me explain. ARPU - Average Revenue Per User - that's all […]

Interesting Failures - Visual IVRs


Another in an occasional series of blog posts where I discuss products I've worked on which failed. It was the early 2000s and the large mobile telco I worked for had just spent billions of pounds on a 3G license. 3G was the future! Sure, faster data would be nice, but the real money was […]

Review: Svpro 3D Camera - for Android and Raspberry Pi


I've been sent a 3D camera addon to review - the Svpro SV-2560X3D-001 is a £65 stereo camera designed for Android. It will also work with a Raspberry Pi! It looks a little like a Microsoft Kinect - a single bar with two embedded cameras. The camera resolution is 720p on each lens. You can […]

Charity Fundraising Using VR


Walking back from work yesterday, I noticed an unusual set of chuggers - those faux-cheerful folk who try to stop you in the street asking for money. They were fundraising for Unicef. Rather than handing out flyers they were carrying high-tech VR headsets! Using the headset, I was able to take a virtual tour of […]

Photo of a nano SIM card and its plastic housing.

I want to correct a common misconception. Many people think that you can dial the emergency services even if you do not have a SIM in your phone. I see this advice scattered around the web - often telling people to keep an old, SIMless phone for an emergency - and it is dangerously wrong. […]

Many years ago, when I worked for a mobile phone company, a group of us were encouraged to come up with crazy ideas which the organisation could patent. I had one idea come this close to getting through until someone found an unnervingly similar patent and the whole thing was dropped. Well, it has been […]

App Showdown - Zapper 🆚 MusicMagpie


It is time for me to have a clear out. I've got hundreds of books which I've replaced with eBook, CDs which I never listen to, and DVDs I'm ashamed to own. Selling them individually on eBay or Amazon sounds like a lot of hard work... That's where Zapper and MusicMagpie come in. Both offer […]
