Cool tech, clear advice.
Charity-shop amplifiers can be brilliant value—until a tired capacitor turns a bargain into a repair bill. Here’s how to spot failing electrolytics before you hand over cash, and where a sensible DIY check stops.
Plenty of 2026 gadgets wear the word 'repairable' on the box and a bead of adhesive under the screen. This guide shows you how to spot a genuine five-minute cell swap from the spec sheet alone — the fasteners, the spare-parts listings, the warranty language, and the handful of models that actually get it right.
A video doorbell is usually judged on its app, subscription and camera—but the real gatekeeper is often a neglected transformer near the consumer unit. Here’s how to read its voltage and VA rating, test it sensibly, and decide whether a wired smart bell will stay charged through a British winter.
A short UK power cut shouldn't take your broadband, Wi-Fi and file backups down with it. Here's how to size a UPS around a fibre ONT, router and small NAS without buying a data-centre brick you'll never need.
Fairy lights are supposed to make the front room feel cosy, not turn an extension lead into a hand warmer. This is a practical UK load audit for festive lighting: wattage, daisy chains, IP ratings, timers and the 13A socket ceiling.
By half four in November, half the dash cams on British roads are filming expensive grey soup. Here's how to set one up so the footage is actually worth something when an insurer asks for it, from sensor choice and bitrate to parking-mode drain and the right way to hand a clip over.
A charity-shop bargain or car-boot find can be perfectly sound—but the plug on the end of its cable is where the real risk hides. Here’s how to inspect, judge and, if needed, rewire a BS 1363 plug without binning a good gadget.
Loose 18650s, power-tool packs and USB power banks do not enjoy a damp British winter any more than you do. Here is a practical storage plan covering voltages, temperature swings, charger myths and the warning signs that mean a cell should leave the house.
A 2kW heater draws roughly 8.7A, which looks positively roomy next to the 13A stamped on a smart plug. The trouble is that a heater runs for hours, not minutes, and continuous resistive load exposes relay contacts, spring terminals and cheap plastics in ways a kettle never will. Here is what the box tends to leave out, and how to automate winter warmth without turning a £12 accessory into a fire risk.
A travel adapter is brilliant for a fortnight abroad and a terrible thing to leave feeding a monitor for three years. Here’s how to spot the weak links on a UK desk and what to use instead.
Autumn gales and power cuts are part of UK life, but a cheap surge-protected extension lead is not a magic force field. Here’s what a £20 strip can genuinely do, when a UPS or consumer-unit SPD earns its keep, and what your home insurance may actually ask for.
British homes are built to keep warmth in, not push 35°C out. Here's how ambient heat affects routers, consoles and PCs—and the low-cost moves that stop a hot afternoon turning into a random shutdown or a dead SSD.
A £25 multimeter can be genuinely useful for USB-C cables, battery checks and low-voltage tinkering. It can also lull you into a false sense of safety around 230V mains. Here is the honest split between handy budget test gear and a shortcut you should never take.
A headline GPU can make a pre-built look like a bargain, but the parts around it decide whether you are upgrading a PC or babysitting one. Here is the BlueIce five-minute teardown you can do from the product page, plus the questions UK retailers should answer before you pay.
Closed windows, central heating and a winter's worth of pet hair can turn a perfectly decent desktop into a hot, noisy box. Here is a practical 20-minute cooling check you can do before the heating settles in for the season.
Everyone says the Raspberry Pi wins on electricity. At 2026 UK tariffs, the gap is smaller than the folk wisdom suggests—and it may not be the thing that should decide your build. Here's the maths, the noise, the storage, and two honest £150 shopping lists.
No novelty robots, no app-subscription traps, no drone that needs a licence to fly in a park. Just six small, boring, genuinely useful bits of UK tech under £50—each one with what it replaces, who it suits, and the cheaper option you should check first.
A smart thermostat can be a lovely little gadget, but it is not a universal remote for your heating. In UK homes, combi boilers, OpenTherm wiring and older systems can turn a simple swap into a costly lesson. Here is what to check first.
Refurbished phones can be a brilliant way to get flagship hardware for sensible money, but grade labels are about as standardised as pub quiz rules. Here is the five-point check we would run before handing over card details in 2026.
Outdoor cameras, video doorbells and garden sensors are tested in labs, not in a British January. Here’s how to judge IP ratings, beat condensation, sort out Wi-Fi at the end of the garden, and install gear so it survives frost, rain and a gutter with ideas above its station.
