I am easily influenced. At EMF Camp, I saw my friends Skylar and Cameron using some nifty walkie-talkies out in the field. Skye (patiently) explained to me the joys of PMR446 and - because I was quite drunk I hastily bought some radios on Amazon. Hey, they were on special - £30 for a pair! After a few days of use, I've come to the conclusion that they're… basically fine? My main reason for bu…

I've got a fancy new Framework laptop. It comes with little expansion sockets - which allow you to plug in USB devices, HDMI ports, Ethernet cables, and all sorts. I want to add an NFC reader to it. So, step one was to find an NFC circuit board which worked with the hardware and was relatively small. Enter the ACM1252U-Z2. It works perfectly with Linux. It has a USB-Micro socket - but a…

The Framework laptop has several little slots which can be used be used to expand the functionality of the laptop. They convert the internal USB-C ports into a different sort of port. For example, Framework sells an official HDMI card and Ethernet card: But the community have built their own SD card expansion pack as well as 3D printed snack drawers: Brilliant! I have an NFC-only…

I needed to read and write NFC cards on Linux. I only buy USB-C peripherals now, so I found the brilliantly named "ACR1252U-MF" which appears to be the only USB-C reader on the market. Total cost was about £35 on eBay. It's a cheap and light plastic box with a short USB cord. When you plug it in, there's a flashing light which can't be disabled. When it is powered up, or it detects and NFC chip, …

The lovely people at Mokin keep sending me their USB-C hubs to review, and I'm happy to do so. They work splendidly with my Linux and Windows machines, and they provide more ports than I ever thought necessary. This one is positively festooned with extra ports. Let's take a look. USB-C Plug your power adapter into the hub, and then the hub into your laptop. With most hubs, that's it; you've…

You can never have too many USB-C ports, right? It's rubbish having a cheap laptop with only a single USB-C port. So, the good folks at Mokin have sent me a gadget which turns your single and lonely USB-C port into FIVE USB-C ports. Along the side you get 4 USB-C 3.1 ports which are theoretically capable of 10Gbps in aggregate. At the bottom is a USB-C 3.0 Power Delivery port which can take…

Supertoys last all summer long! But batteries do not. The last set of rechargeable batteries I had leaked everywhere, and I could never find the right charging lead for the gizmo which pumped power into them. So let's cut out the middle-man and plug a USB-C cable straight into our batteries! What? These were the cheapest AA batteries I could find which took USB-C. £16 including delivery, for …

I genuinely think that USB-C might be the defining feature of the 21st century. A little port which is cheap enough to add to the most trivial of devices, and that can carry an impressive amount of power and data. All of my gadgets have it - phone, eReader, headphones, laptop, thermal printer, battery, games console - and now, my mosquito bite zapper! This is the "heat it" - it's about £30 on …

The good folks at Fifine have sent me this neat little microphone to review. Unboxing Sound Quality Writing about microphones is like painting about flavour. So here's what it sounds like: 🔊 💾 Download this audio file. No noticeable hiss. Captured my voice perfectly. It picked up a little clack from my keyboard as I typed. Colleagues could hear me clearly - even if they were som…

All USB-C cables are equal. But some, as the saying goes, are more equal than others. This little gadget from Plugable is a fantastic bit of kit. Plug your USB-C power supply into one end of the gadget, plug the gadget in to your laptop, phone, or any other USB-C device. Watch the screen to see how much power is flowing. Action Shot …

I'm writing this post in the hope someone will rip off my idea and start selling it on Ali Express. Many years ago, I got a "Pressy". It was a little dongle which fitted into your phone's headphone jack. It had a single button on the top. It came with an app so when you tapped the button the app would do something. For example, tap once to open email, double-tap to switch to flight mode, etc. …
